Background: There are limited data about predictors of atrial fibrillation (AF) recurrence after totally thoracoscopic ablation (TTA). This study investigated the clinical implication of left atrial appendage emptying velocity (LAAV) in patients undergoing TTA.Methods and Results: Patients who underwent TTA between 2012 and 2015 at a tertiary hospital were prospectively enrolled in this study. LAAV was measured and averaged over five heart beats from preoperative transesophageal echocardiography. The primary outcome was a freedom from recurrent AF or atrial flutter (AFL) detected on 24-h Holter monitoring or an electrocardiogram over a 3-year period after TTA. In all, 129 patients were eligible for analysis in this study. The mean (±SD) patient age was 54.4±8.8 years, and 95.3% were male. During the 3 years after TTA, the overall event-free survival rate was 65.3%. LAAV was an independent predictor of recurrent AF/AFL during the 3-year period after TTA (per 1-cm/s increase, adjusted hazard ratio [aHR] 0.95; 95% confidence interval [CI] 0.91–0.99; P=0.016). Event-free survival was significantly lower among patients with a low LAAV (<20 cm/s; n=21) compared with those with a normal (≥40 cm/s; n=38; aHR 6.11; 95% CI 1.42–26.15; P=0.015) or intermediate (LAAV ≥20 and <40 cm/s; n=70; aHR 2.74, 95% CI 1.29–5.83; P=0.009) LAAV.Conclusions: In patients with AF, LAAV was significantly associated with the risk of long-term recurrence of AF after TTA.

Background: Infective endocarditis (IE) in cancer patients is increasing, but because little is known about it in these patients, we analyzed patient characteristics and outcomes and compared these factors in IE patients with and without cancer. Methods and Results: This retrospective cohort study included 170 patients with IE newly diagnosed between January 2011 and December 2015. Among 170 patients, 30 (17.6%) had active cancer. The median age of IE patients with cancer was higher than that of non-cancer patients. Nosocomial IE was more common in cancer patients. Non-dental procedures, such as intravenous catheter insertion and invasive endoscopic or genitourinary procedures, were more frequently performed before IE developed in cancer patients. Staphylococcus was the most common pathogen in cancer patients, whereas Streptococcus was the most common in non-cancer patients. In-hospital mortality was significantly higher in cancer patients with IE (34.4% vs. 12.4%, P<0.001). IE was an important reason for discontinuing antitumor therapy and withholding additional aggressive treatment in nearly all deceased cancer patients. Conclusions: IE is common in cancer patients and is associated with poorer outcomes. Patients with IE and cancer have different clinical characteristics. Additional studies regarding antibiotic prophylaxis before non-dental invasive procedures in cancer patients are needed, as cancer patients are not considered to be at higher risk of IE.
