An increasing number of children with congenital heart disease are surviving into adulthood and subsequently developing end-stage heart failure. Two example populations are adults who have been previously operated on for congenitally corrected transposition of the great arteries (CCTGA) and transposition of the great arteries (TGA). Implantation of a continuous flow left ventricular assist device (CF-LVAD) in these patients can present unusual anatomical and physiologic challenges. In this report, we describe outcomes of CF-LVAD implantation in three such patients. These cases demonstrate the feasibility of implanting a CF-LVAD in patients who have undergone surgery for CCTGA and/or TGA.

In patients with obstructive hypertrophic cardiomyopathy, left ventricular outflow tract (LVOT) obstruction can be created by the hypertrophic interventricular septum (IVS) as well as systolic anterior motion (SAM) of the anterior mitral leaflet (AML). Sufficient septal myectomy is a fundamental surgical technique to treat LVOT obstruction, however, direct surgical management for SAM is another key aspect. Besides the hypertrophic IVS, mitral valve, subvalvular apparatus, and papillary muscle may play important role for SAM and several surgical techniques have been proposed to treat SAM in literature. In this review, each surgical technique is classified by the anatomical structure on which the surgical procedure is applied. The AML is the main surgical site and is applied with plication (vertical plication, resection–plication–release strategy), extension (the AML extension, transverse incision of the AML), sutured (edge-to-edge repair, anterior leaflet retention plasty), or traction (floating stitch, papillary muscle-to-anterior annulus stitches, paradoxical stitches, transposition of a directed chorda tendinea to the AML). Height reduction of the posterior mitral valve leaflet and papillary muscle reorientation are other techniques. We should understand theoretical aspects of each technique on correction of anatomical and functional abnormalities of the structure and should apply them under proper indication.

Objective: To compare the effectiveness of surgical versus nonsurgical treatment for multiple rib fractures accompanied with pulmonary contusion.Methods: The clinical records of consecutive 167 patients with multiple rib fractures accompanied with pulmonary contusion, who were treated from June 2014 to June 2017, were retrospectively analyzed. Of them, 75 and 92 underwent surgery (surgery group) and non-surgical treatment (non-surgery group), respectively. Patient pain score, complications, length of hospital stay, cost of hospitalization, and post-treatment 3-month follow-up results were compared.Results: The mean number of days and moderate pain in the surgery group was significantly lower than that of the non-surgery group (p <0.01). The incidence of post-treatment complications was significantly lower in the surgery group than in the non-surgery group. The length of hospital stay of the surgery group was also significantly shorter than that of the non-surgery group (p <0.01). The cost of hospitalization was significantly higher in the surgery group than in the non-surgery group (p <0.01). The chest computed tomography (CT) scan which was performed 3 months after the treatment revealed that the surgery group had a better recovery than the non-surgery group. Physical recovery of the surgery group was also significantly better than that of the non-surgery group.Conclusion: Surgery to treat multiple rib fractures (≥ 4 fractures) accompanied with pulmonary contusion is safe and effective.

Background: Concomitant mitral regurgitation (MR) is frequently seen in patients undergoing surgical aortic valve replacement (AVR) for severe aortic stenosis (AS). When the severity of MR is moderate or less, the decision to undertake simultaneous mitral valve intervention can be challenging.Methods: A systematic search of Medline, PubMed (NCBI), Embase and Cochrane Library was conducted to qualitatively assess the current evidence for concomitant mitral valve intervention for MR in patients with AS undergoing AVR. The primary outcome for this systematic review was the postoperative change in the severity of MR and other outcomes of interest included factors that predict improvement or persistence of MR and long-term impacts of residual MR.Results: A total of 17 studies were included. The percentage of patients demonstrating improvement in MR severity following AVR ranged from 17.2% to 72%; the studies that exclusively included patients with moderate functional MR and reported longer term echocardiographic follow-up of greater than 12 months demonstrated an improvement in MR severity of 45% to 72%.Conclusion: This systematic review demonstrates that a proportion of patients can exhibit an improvement in MR following isolated surgical AVR, but whether this confers any long-term morbidity and mortality benefit remains unclear.

Purpose: This study aims to analyze the clinical outcomes after isolated mitral valve (MV) repair in patients with reduced left ventricular ejection fraction (LVEF <50%) with focus on perioperative characteristics, survival, and freedom from reoperations.Methods: Between 1997 and 2015, 557 patients with reduced LVEF (age: 62.8 ± 11.7 years, male: 320) underwent MV repair for symptomatic mitral regurgitation (MR). Etiologies were dilated non-ischemic cardiomyopathy and ischemic cardiomyopathy in 487 (87.4%) and 70 (12.6%) patients, respectively; these were classified into three different subgroups: LVEF 40%–49% (group 1), 30%–39% (group 2), and <30% (group 3).Results: Overall, 294, 145, and 118 patients had an LVEF of 40%–49%, 30%–39%, and <30%, respectively. Logistic EuroSCORE was significantly higher (P <0.001) as the LVEF worsened. The survival analysis for groups 1–3, respectively, revealed the following: 30-day mortality: 1.4%, 3.4%, and 7.6% (P <0.001); 1-year survival: 93.9%, 89.4%, and 82% (P <0.001); 5-year survival: 81.2%, 75.2%, and 58% (P <0.001).Conclusion: MV repair in patients with impaired LVEF could be performed safely with good clinical short- and mid-term outcome. Nevertheless, reduced preoperative LVEF correlates with worse perioperative and long-term survival.

Metal allergy is an uncommon problem during surgery. Among them, titanium allergy is said to be rare, but can lead to serious complications, such as palmoplantar pustulosis (PPP). A 69-year-old woman was admitted to our hospital with a chief complaint of chest pain. Coronary angiography showed severe coronary artery disease that required coronary artery bypass grafting (CABG). The patient had a history of orthopedic surgery for left distal radius fracture 2 years previously, which resulted in inflammation on the left arm and PPP. We suspected titanium allergy based on results of skin patch tests and use of titanium alloy in the previous orthopedic operation. The patient underwent CABG without use of permanent metallic material. As a result, her PPP disappeared. In this rare case, it is difficult to identify the exact cause of the improvement in PPP; thus, further studies are required to clarify the mechanism of remission.

Mechanical circulatory support may result in sufficient myocardial recovery to allow for explantation of the left ventricular assist device (LVAD). The duration of support associated with left ventricular recovery has generally been 6–12 months. In this report, we present a patient in whom the left ventricle recovered after 5 years of support with a LVAD. Our report demonstrates that long-term monitoring for left ventricular recovery is prudent and may allow for late device explantation.

Patients undergoing cardiac surgery remain on mechanical ventilation postoperatively until they regain consciousness. Positive end-expiratory pressure (PEEP) may influence the duration of mechanical ventilation after coronary artery bypass grafting (CABG). The aim of this study was to compare the effects of different levels of PEEP on the duration of mechanical ventilation after coronary artery bypass grafting. This was a randomized clinical trial with 136 patients undergoing CABG between January 2011 and March 2012. We divided the patients into three groups with different levels of PEEP at the onset of mechanical ventilation: Group A, PEEP = 5 cmH2O (n = 44); Group B, PEEP = 8 cmH2O (n = 47) and Group C, PEEP = 10 cmH2O (n = 45). Mechanical ventilation time was obtained from a Physical Therapy Evaluation Form. We excluded patients with chronic obstructive pulmonary disease and those requiring concomitant, emergency or off-pump surgeries. For statistical analysis, we used the Kruskal-Wallis, G and Chi-square tests, with p <0.05 considered significant. From the point of weaning from mechanical ventilation until 12 hours after intensive care unit (ICU) admission, we saw a statistically different duration of mechanical ventilation between groups (p = 0.029). In Group A, the average mechanical ventilation time was 6.7 ± 3.2 hours; it was 6.8 ± 3.3 hours in Group B and 5.1 ± 2.9 hours in Group C. The use of higher levels of PEEP was associated with shorter duration of mechanical ventilation in postoperative CABG patients.

Purpose: Pleurodesis continues to play a central role in the management of pneumothorax. In our institute, a 50% glucose solution is used for pleurodesis. We retrospectively analysed the treatment effects of pleurodesis in patients with spontaneous pneumothorax in whom an operation was contraindicated because of underlying disease.Methods: 13 patients (18 cases) with spontaneous pneumothorax were treated with pleurodesis with a 50% glucose solution. After local anesthesia of parietal pleura, 200 to500 mL of a 50% glucose solution was instilled into the pleural space. Pleurodesis was repeated two or three times, until the air leakage stopped.Results: Air leakage stopped in all cases and there were no treatment-related deaths.Overall survival rates at 1, 2, and 3 years after treatment were 83%, 74%, and 49%, respectively. Post-treatment recurrence was observed in six cases. Four cases of recurrence were treated with pleurodesis with a 50% glucose solution. All cases of recurrence occurred within 3 months after pleurodesis.Conclusion: Pleurodesis with a 50% glucose solution is effective and safe in patients with pneumothorax. This procedure can be performed in patients with recurrent pneumothorax as well as patients with a first episode of pneumothorax in whom prolonged air leakage is predicted.

A 32-year-old man presented to our hospital after a failed suicide attempt using a crossbow. The patient had shot himself in close range with a double-barreled crossbow, simultaneously two arrows, in the chest. In spite of his life-threatening injuries, the man survived. The lodged arrows helped to avoid tremendous loss of blood. After his arrival in the hospital, the surgical removal of the arrows proceeded under direct visualization with corresponding sutures on the heart and liver. The patient's postoperative course was uneventful.

This paper focuses on the latest research of diffusion-weighted magnetic resonance imaging (DWI), and deals with economic benefits, diagnostic benefits, and prospects of DWI for lung cancer. The medical cost of a magnetic resonance imaging (MRI) is 81%–84% cheaper than that of 18-fluoro-2-deoxy-glucose positron emission tomography/computed tomography (FDG-PET/CT). DWI is reported to be useful for differential diagnosis of malignancy or benignity for neoplasm in various organs. Diagnostic efficacy by DWI for pulmonary nodules and masses and the evaluation of N factor and M factor in lung cancer are equivalent to or more than that of FDG-PET/CT. The diagnostic capability of whole-body DWI (WB-DWI) for the staging of clinically operable lung cancers is equivalent to that of FDG-PET/CT and brain MRI, and WB-DWI is now becoming a more main stream procedure. Although the diagnostic performance of DWI for lung cancer may be equivalent to that of FDG-PET/CT, prospective randomized controlled trial for comparison of diagnostic efficacy between FDG-PET/CT and DWI for lung cancer is necessary for an accurate comparison. DWI may have an advantage in the aspect of the cost and diagnostic efficacy in lung cancer management.

We report a 64-year-old man with incidentally found uncorrected total anomalous pulmonary venous connection (TAPVC). There have been only a few case reports of untreated TAPVC diagnosed after 60 years of age. Also, this is a first case report of TAPVC in which ECG-gated CT and phase-contrast cine magnetic resonance imaging (PC-MRI) was performed. He was referred to our hospital for the surgery of rectal cancer. He had been diagnosed to have an arterial septal defect (ASD) and persistent left superior vena cava (PLSVC), and Eisenmenger’s syndrome was thought to be the cause of cyanosis at first. The vertical vein in TAPVC was initially misdiagnosed as PLSVC on enhanced axial CT images reconstructed with 5-mm slice thickness with gapless. ECG-gated CT and PC-MRI were useful to confirm the diagnosis. The vertical vein in TAPVC is morphologically similar to PLSVC. This kind of abnormality would be somewhat difficult to diagnose on non-ECG-gated CT, and might be misdiagnosed as a large ASD and PLSVC.

From April 2018 to February 2021, 150 patients underwent MitraClip implantation for severe functional mitral regurgitation (MR) at our hospital. Two of our patients, an 85-year-old man and an 84-year-old woman, developed a single leaflet device attachment in the acute phase after the implantation and had severe residual MR requiring surgical correction. The recurrent MR was first pointed out on day 5 and day 4, and the duration between MitraClip implantation and surgery was 13 and 55 days, respectively. Due to strong adhesions with the clips and severe valve damage after MitraClip implantation, both cases underwent mitral valve replacement with a good postoperative course. In patients with a high-risk baseline profile, surgical mitral valve replacement after failed MitraClip implantation should be considered at an optimal timing, and a detailed echocardiographic follow-up is required.

Purpose: This study aimed to illustrate how percutaneous balloon mitral valvuloplasty (PBMV) and mitral valve (MV) surgeries influence women of childbearing age with rheumatic mitral valve diseases (RMVDs) from two aspects, including clinical outcomes and their postoperative childbearing performances.Methods: Female patients with RMVD who were of childbearing age and underwent MV interventions between 2007 and 2019 at Beijing Anzhen Hospital were identified. Outcomes included all-cause deaths, repeated MV interventions, and atrial fibrillation. A survey about childbearing attempts and complications during pregnancy was also performed during follow-up.Results: A total of 379 patients were involved in this study, consisting of 226 cases of mitral valve replacements, 107 cases of mitral valve repairs (MVrs), and 46 cases of PBMVs. PBMV was associated with higher possibilities of repeated MV interventions (P <0.05). Postoperative childbearing attempts were more frequently observed among bioprosthesis, MVr, and PBMV (P <0.05). However, PBMV and MVr showed a higher incidence of cardiac complications during pregnancy as compared to prosthesis replacement (P <0.05).Conclusions: MVr and PBMV are not recommended to young female patients for higher incidences of postoperative complications. Safe pregnancy is more likely to be present among patients with biological prosthesis.

Purpose: This study explored the sex differences in the outcomes of degenerative mitral valve repair (MVr).Methods: From 2010 to 2019, 1069 patients who underwent MVr due to degenerative mitral disease at Beijing Anzhen Hospital were analyzed. The average patient follow-up was 5.1 years (interquartile range: 5–7 years). The primary endpoint was overall survival. Secondary endpoints were freedom from reoperation and recurrent mitral regurgitation. A propensity-matched analysis was used to compare the outcomes of males and females.Results: Females were older, had a higher prevalence of atrial fibrillation and moderate-to-severe tricuspid regurgitation, and had smaller left atrial, left ventricular end-diastolic, and left ventricular end-systolic diameters. Males were more likely to undergo concomitant coronary artery bypass grafting and had longer cardiopulmonary bypass and aortic cross-clamp times. The in-hospital mortality was <1% (10/1,069). After propensity score matching of 331 pairs of patients, most variables were well balanced. Before and after propensity score matching, the long-term survival and freedom from reoperation rates were similar. Males had higher durability after surgery compared with females.Conclusions: Females were referred to surgery later and had more complications than males. Long-term survival and freedom from reoperation rates were not significantly different between the sexes.

Purpose: We studied the association between operative timing and the feasibility of mitral valve (MV) repair in active infective endocarditis (IE).Methods: Forty-nine active IE patients who underwent MV operation were classified according to operative timing: within 48 hours (Term I: n = 7), between 3 and 14 days (Term II: n = 22), and ≥15 days (Term III: n = 20). Patient profiles, operative outcomes, and feasibility of MV repair were evaluated. Complexity score and severity score were used to define the feasibility of MV repair depending on the extent of infected lesion and technical difficulties.Results: There were no differences in basic profile in the three groups. Rate of major complications was higher in Term I (86%) than II (41%, p = 0.031) and III (25%, p = 0.005). In-hospital mortality was also higher in Term I (43%) than II (9%, p = 0.039) and III (5%, p = 0.015). The three groups did not differ by feasibility of MV repair calculated by the two-score system or by frequency of MV repair (I: 57%, II: 59%, and III: 55%).Conclusions: Morbidity and mortality were high in urgent cases. Feasibility of MV repair is associated with the extent of infected lesion and technical difficulties, and not with operative timing.

Purpose: A pneumothorax occurs in 3%–8% of patients with idiopathic pulmonary fibrosis. A pneumothorax may predict a poor outcome in patients with interstitial lung disease (ILD), and it is difficult to treat patients with ILD and a pneumothorax.Patients and Methods: We retrospectively studied data from all 12 patients with ILD and a pneumothorax who underwent surgical treatment at Toho University Omori Medical Center Hospital between 2009 and 2021.Results: Of the 12 patients, 2 had home oxygen therapy preoperatively and were classified with grade IV interstitial pneumonia (IP). Six patients had preoperative pleurodesis and two had postoperative one using auto-blood. Three patients (25%) had multi-step surgery ≥2, and 5 patients had surgical resection of bullae. No patients had postoperative acute exacerbations and all were discharged from the hospital in a stable condition. The 5-year overall survival rate for all patients was 70.0%. The median survival time was not reached. One patient with unclassified IP was doing well 116 months after surgery.Conclusion: Patients with ILD and a pneumothorax were shown to require multi-step surgical treatment and can anticipate long-term survival.

Purpose: We aimed to compare the efficacy of radiofrequency ablation (RFA) in patients undergoing mitral valve (MV) surgery with or without giant left atria.Methods: This retrospective, single-center, cohort study investigated patients who underwent MV surgery and concomitant RFA from 2009 to 2019. Patients were divided into non-giant left atria (diameter ≤65 mm, n = 1543) and giant left atria (diameter >65 mm, n = 241) groups. Five-year freedom from atrial tachyarrhythmia recurrence and thromboembolic event (TE) rates were assessed with death as the competing risk factor with and without propensity-score matching.Results: Patients with giant left atria had higher mortality (10.8% versus 6.2%, P = 0.008) and readmission rates for heart failure than those without (12.0% versus 6.8%, P = 0.004). Atrial tachyarrhythmia recurrence rates were higher in patients with giant left atria than in those without (49% versus 24% at 5 years, P <0.001), but the cumulative incidence of TEs before (P = 0.944) and after (P = 0.695) propensity-score matching was comparable.Conclusions: RFA effectively prevented TEs in patients with giant left atria, despite significant atrial tachyarrhythmia recurrence. Atrial tachyarrhythmia recurrence did not increase the risk of TEs. A lower success rate should be considered when deciding whether to perform surgical ablation in patients with giant left atria.

Purpose: Our aim was to evaluate the development of new significant mitral regurgitation and long-term survival after mitral repair surgery in functional mitral regurgitation.Methods: A retrospective observational analysis of the recurrence of functional mitral regurgitation (ischemic and nonischemic) and global mortality during follow-up of 176 patients who underwent mitral repair surgery between 1999 and 2018 in our center was conducted.Results: The etiology of functional mitral regurgitation was ischemic in 55.7% of cases. After surgery, mitral regurgitation was 0-I in 92.3% of cases. We conducted a long-term clinical follow-up of a mean 42.2 months and an echocardiographic follow-up of a mean 41.8 months. We observed mitral regurgitation of at least grade II in 52 patients (36.9%). Survival at 1, 3, and 5 years was 78.8%, 66.7%, and 52.3%, respectively. Predictive factors for global mortality were age (hazard ratio = 1.038, p = 0.01) and a depressed preoperative ejection fraction. After a competing risk analysis, we found the only predictive factor for the recurrence of mitral regurgitation in our series to be age (sub-hazard ratio = 1.03, 95% confidence interval = 1.01–1.06, p = 0.016).Conclusion: Repair surgery for functional mitral regurgitation shows age as the only independent predictor of recurrence. Age and depressed ejection fraction were predictors of mortality.
