Single-stage extended replacement from the ascending to the distal descending aorta or beyond is a formidable operation that should be preserved for those who have no other option or those who are physically fit, and should be performed in the experienced centers. Hybrid operations combining open surgical repair with thoracic endovascular aortic repair through a median sternotomy incision are preferable because these operations are less invasive than the extended open aortic repair and the risk of spinal cord ischemia is lower compared with the frozen elephant trunk operation. However, these operations are associated with the inherent demerits of endovascular aneurysm exclusion. When the underlying aortic pathology necessitates extended open aortic repair in a single stage, approaches such as the anterolateral partial sternotomy, straight incision with rib cross, and extended thoracotomy with sternal transection may be useful to provide sufficient exposure for both aortic reconstruction and organ protection, with less surgical stress to the patients.

Purpose: Total aortic arch replacement (TAR) with frozen elephant trunk (FET) is the standard operation for treating aortic dissection (AD) patients involving aortic arch with high operative risk due to long circulatory arrest (CA). We used aortic balloon occlusion technique that safely reduced the CA time to 5 min in average and investigated whether it can improve the clinical endpoints.Methods: All patients diagnosed with AD and underwent TAR with FET operation (123 with aortic balloon occlusion and 221 with conventional method) in Fuwai Hospital during August 2017 and February 2019 was reviewed in this retrospective observational study.Results: After propensity score matching, the 30-day mortality of aortic balloon occlusion group and conventional group was 4.88% and 11.38% (P = 0.062), respectively. In multivariate analysis, aortic balloon occlusion is one of the factors that reduced the risk for renal and hepatic injury, shortened postoperative conscious revival time, and reduced red blood cell (RBC) transfusion during operation.Conclusions: The aortic balloon occlusion technique, as a perfusion strategy during operation, could alleviate postoperative complication. This method deserves further attention in future clinical practice for its value in treating patients with higher operative risks.

Purpose: The effect of our comprehensive strategy to reduce pain after minimally invasive mitral valve repair through a right mini-thoracotomy was assessed retrospectively.Methods: Our comprehensive strategy constituted the following: planned rib cutting to avoid rib injury, sufficient intercostal muscle division to mobilize the cut rib, limiting the number of intercostal ports, avoiding nerve entrapment, continuous extra-pleural intercostal nerve block, and regular use of oral non-steroidal anti-inflammatory drugs. We compared patients treated with this comprehensive strategy (Group S, n = 13) and patients before this strategy was implemented (Group C, n = 13). We used a numerical rating scale (NRS) as a pain scale during the first 3 days postoperatively.Results: The average NRS was significantly lower in Group S (0.82 ± 0.49) than in Group C (2.40 ± 1.46) (P <0.01). The maximum NRS was also significantly lower in Group S (3.23 ± 1.17) than in Group C (5.69 ± 2.43) (P <0.01). The number of patients using additional single-dose analgesic were significantly less in Group S (23.1%) than in Group C (84.6%) (P <0.01).Conclusion: Our comprehensive pain control strategy effectively reduced postoperative pain in minimally invasive mitral valve repair.

Purpose: Blood loss along with inadequate evacuation after cardiac surgery leads to retained blood syndrome (RBS) in the pleural and/or pericardial cavity. Re-sternotomy is often needed for clot evacuation. Video-assisted thoracoscopic surgery (VATS) evacuation is a less-invasive procedure. However, sufficient evidence on safety and outcomes is lacking.Methods: Thirty patients who developed hemothorax and/or hemopericardium after cardiac surgery and underwent VATS evacuation between April 2015 and September 2020 were included in this retrospective single-center analysis.Results: The median patient age was 70 (interquartile range: IQR 62–75) years, body mass index (BMI) was 24.7 (IQR 22.8–29) kg/m2, time between initial cardiac surgery and VATS was 17 (IQR 11–21) days, 30% of the patients were female, 60% resided in the ICU, and 17% were nicotine users. Coronary artery bypass graft was the most frequent initial cardiac procedure. Median operation time was 120 (IQR 90–143) min, 23% of the patients needed an additional VATS, and the median length of hospital stay after VATS was 8 (IQR 5–14) days. All patients survived VATS, and we experienced no mortality related to the VATS procedure.Conclusion: In our study, VATS for evacuation of RBS after cardiac surgery was a feasible, safe, and efficient alternative approach to re-sternotomy in selected patients.

Objective: Mitral subvalvular procedures in addition to restrictive annuloplasty are promising for ischemic mitral regurgitation (IMR). However, the prevalence and efficacy of specific subvalvular repair in severe IMR have not been elucidated. This is the first nationwide survey regarding surgeons’ attitudes toward IMR in Japan.Methods: A questionnaire was sent to 543 institutions. From 2015 to 2019, numbers of elective first-time mitral valve replacement (MVR) with/without complete chordal preservation (CCP)/papillary muscle approximation (PMA) and mitral valvuloplasty (MVP) with/without papillary muscle relocation (PMR)/PMA in patients with severe IMR were collected. Concomitant procedures for coronary artery, tricuspid valve, and arrhythmia could be included but left ventricular reconstruction was excluded.Results: Completed questionnaires were received from 286 institutions (52.7%). The majority (90%) had less than 20 cases within 5 years. The number of MVP (1413, 61.5%) surpassed MVR (886, 38.5%). CCP was performed in half of MVR (50.0%), while PMA was included in only 1.9% of MVR. PMA and PMR were also performed infrequently, in only 7.7% and 10.9% of MVP, respectively.Conclusion: Japanese surgeons aggressively perform MVP for severe IMR. Subvalvular repair was also aggressively performed in addition to MVR, but not to MVP. A multicenter registry study is in progress.

Purpose: To evaluate the utility of ultrasonographic assessment of blood flow to the lower limb below the cannulation site in minimally invasive cardiac surgery (MICS).Methods: Twenty-two patients who underwent ultrasonographic assessment in MICS were reviewed retrospectively. In all patients, the right femoral artery was used for arterial cannulation. Ultrasonographic assessment was performed using a 15-MHz ultrasonography small probe, and regional oxygen saturation was monitored by near-infrared spectroscopy (NIRS).Results: The mean flow velocity at the distal side of the cannulation site was 46.2 ± 25.4 cm/s. In six patients, a >40% decreased from baseline regional oxygen saturation was observed. In five of the six patients, the flow velocity was very slow, and spontaneous echo contrast was also observed in three cases. Their regional oxygen saturation was improved rapidly after distal leg perfusion. In the remaining case, the flow velocity was not decreased. In another one case, the stenosis at the cannulation site was detected after decannulation and repaired immediately. No limb ischemic complications were observed in this series.Conclusion: Ultrasonographic assessment combined with the NIRS monitoring is useful to prevent lower limb ischemic complications after femoral arterial cannulation in MICS.

Purpose: Recently, guidelines recommended the use of direct oral anticoagulants (DOACs) for the management of non-valvular atrial fibrillation (NVAF). Postoperative atrial fibrillation (POAF) is the most common post-surgical complication of cardiac surgery, but the efficacy and safety of DOAC for POAF have rarely been investigated. We conducted a prospective observational study to investigate the efficacy and safety of DOAC administered immediately after POAF.Materials and Methods: In all, 135 patients that experienced POAF after cardiac surgery were treated with a DOAC. Primary endpoints were either bleeding or thromboembolic events. Secondary endpoints included changes in hemoglobin (Hb), prothrombin time (PT), activated partial thromboplastin time (APTT), serum creatinine (sCr), estimated glomerular filtration rate (eGFR), and pleural/pericardial effusion.Results: Patients were treated with apixaban (n = 31), edoxaban (n = 87), and rivaroxaban (n = 17). Major bleeding (p = 0.011) and gastrointestinal (GI) bleeding (p = 0.047) were significantly more frequent in the rivaroxaban group. Stroke was observed in one rivaroxaban group patient and none in the other two groups.Conclusion: DOAC as anticoagulation therapy for the early intervention of POAF following cardiac surgery is associated with a low incidence of major bleeding; a favorable safety profile and excellent efficacy were demonstrated for DOAC. Furthermore, our results indicate that the safety and efficacy of apixaban and edoxaban are better than rivaroxaban.

Trifecta is a stented bioprosthetic heart valve with a bovine pericardial sheet externally mounted on a titanium stent. This valve is applied only for aortic valve replacement (AVR), providing excellent hemodynamics and extremely low incidence of structural valve deterioration (SVD). A 76-year-old woman presented with dyspnea on effort 24 months after AVR with a 21-mm Trifecta valve. Echocardiography revealed severe aortic regurgitation with prolapse of a cusp of Trifecta valve, which suggested that she developed acute heart failure due to early SVD. In the operation, Trifecta valve had a cusp tear near the commissure with circumferential fibrous pannus ingrowth only at the inflow side. There was neither calcification nor infection. The Trifecta valve was successfully replaced with a new porcine bioprosthesis.

Background: We planned to investigate the effect of preoperative short period intensive physical therapy on lung functions, gas-exchange, and capacity of diffusion, and ventilation-perfusion distribution of patients with non-small cell lung cancer.Methods: Sixty patients with lung cancer, who were deemed operable, were randomly allocated into two groups. Intensive physical therapy was performed in patients in the study group before operation. Both groups received routine physical therapy after operation.Results: There was no difference in pulmonary function tests between the two groups. Intensive physical therapy statistically significantly increased peripheral blood oxygen saturation. At least one complication was noted in 5 patients (16.7%) in the control group, and 2 (6.7%), in the study group. However, there was no statistically significant difference (p = 0,4). The hospital stay has been found to be statistically significantly shortened by intensive physical therapy (p <0.001). Ventilation-perfusion distribution was found to be significantly effected by intensive physical therapy. The change was prominent in the the contralateral lung (p <0.001).Conclusions: Intensive physical therapy appeared to increase oxygen saturation, reduce hospital stay, and change the ventilation/perfusion distribution. It had a significant, positive effect on the exercise capacity of patients.

We report the use of glutaraldehyde (GA) in a case of valve repair for mitral valve prolapse associated with active infective endocarditis. GA scrubbed at the site of infection decontaminates and reinforces infected fragile tissue, avoids excessive debridement, and strengthens the edges of valve leaflets to facilitate suturing.

Introduction: Congenital tracheal stenosis (CTS) with a bilateral tracheal bronchus (TB) has not been reported as a subtype of CTS. A novel technique to manage CTS in patients with a bilateral TB is described.Case Report: An infant with tetralogy of Fallot underwent repair of cardiac anomaly at age 1 month. He experienced numerous cyanosis and episodes of transient respiratory arrest. Chest computed tomography (CT) demonstrated an aberrant bilateral upper lobe bronchus arising directly from the trachea and a stenotic trachea connecting the pseudo- carina to the true carina between the common right lower and left lower bronchus. On bronchoscopy, the diameter of the lumen of the narrowed segment was estimated to be less than 2 mm. Tracheal reconstruction was undertaken when he was 2 years of age. The surgical technique using a modified slide tracheoplasty for the correction of this anomaly are described. After surgery, the patient was extubated and has had no respiratory symptoms.Discussion and Conclusion: The patient had unique anatomic considerations that made reconstruction challenging. Our technique of covering a stenotic section by normal trachea is a modification of the slide tracheoplasty technique and is useful for CTS with a unilateral and a bilateral TB.

Background: The TROFEO trial demonstrated that febuxostat causes greater and more rapid reduction of serum uric acid (s-UA) than topiroxostat. We compared these drugs in patients with chronic kidney disease (CKD) by sub-analysis of the TROFEO trial.Methods: This sub-analysis targeted patients with an estimated glomerular filtration rate (eGFR) ≤60 mL/min/1.73 m2. The primary endpoint was the s-UA level. Secondary endpoints included creatinine, eGFR, urinary albumin, cystatin-C, oxidized low-density lipoprotein (Ox-LDL), eicosapentaenoic acid/arachidonic acid ratio, lipid biomarkers, high-sensitivity C-reactive protein, and B-type natriuretic peptide (BNP).Results: There was no significant difference of s-UA between the two groups either before or after treatment. However, s-UA did not exceed 6.0 mg/dL in febuxostat group during the study period, but it exceeded this level in seven patients from topiroxostat group, with the number being significantly higher in topiroxostat group. Serum creatinine (s-Cr) and eGFR were significantly better after 6 months of febuxostat treatment compared with topiroxostat Cystatin-C was significantly lower after 6 months of febuxostat treatment compared with topiroxostat. The Ox-LDL was significantly lower after 3 and 6 months of febuxostat treatment compared with topiroxostat.Conclusion: Febuxostat had stronger renoprotective and antioxidant effects than topiroxostat in patients with hyperuricemia and CKD.

<p>The standard treatment for stroke risk patients with non-valvular atrial fibrillation (NVAF) is the use of oral anticoagulants (OACs). However, a substantial number of patients have relative or absolute contraindications to OACs due to concerns of major bleeding risk and other adverse effects while using oral anticoagulation therapy. Recently, occurrences of exclusion of the left atrial appendage (LAA) in patients with contraindication to anticoagulation therapy are widely expanding worldwide, causing major contentious discussions. The LAA is the commonest place of thrombus formation; therefore, the concept of LAA occlusion in reducing stroke and other embolic events in NVAF patients is very important. The current understanding of the available evidence on efficacy and safety of LAA closure (LAAC) with the Watchman device in patients contraindicated to OACs is the major aim of this focused review. After reviewing a significant body of literature, a world experience with no randomized trials, it is suggested that Watchman device implantation is effective and safe in high-risk patients with NVAF contraindicated to OACs therapy.</p>

We report a case with lung cancer during pregnancy, which has a very poor prognosis.A 34-year old female at 30 weeks of pregnancy came to us with a cough and right lower chest pain. Chest computed tomography revealed a mass in the right lower lung lobe and the diagnosis of adenocarcinoma cT2aN1M0 was made. We performed a right sleeve pneumonectomy, as the tumor had progressed to the right main bronchus near carina. Histological sections of the specimens revealed a poorly differentiated adenocarcinoma that infiltrated surrounding structures. The pathological stage of lung cancer was T4N2M0 stage IIIB. Immunohistochemistry findings for estrogen receptor β were positive in the nuclei of the adenocarcinoma. She had a rapid recurrence in spite of chemotherapy, and she died 7.5 months after operation. The positive estrogen receptor and hormonal condition during pregnancy might promote cancer and result in her poor prognosis.
