Background:Transcatheter aortic valve replacement (TAVR) has been performed more and more frequently in elderly patients with aortic stenosis. We investigated the association of in-hospital availability of TAVR on outcomes of surgical aortic valve replacement (SAVR) in the era of TAVR.Methods and Results:We utilized data from the Japan Adult Cardiovascular Surgery Database. Between October 2013 and December 2016, 9,330 patients aged ≥80 years underwent isolated SAVR or SAVR with coronary artery bypass grafting in 557 centers in Japan. We assessed the associations of in-hospital TAVR availability with operative mortality and composite complications adjusting for each patient’s characteristics, JapanSCORE predicted the risk scores, and hospital volumes of SAVR using generalized estimation equation methods. Observed operative mortality rates were 3.4% in all centers, 2.0% in TAVR centers and 4.0% in non-TAVR centers. The multivariable analyses showed that TAVR centers had statistically significantly lower operative mortality compared with non-TAVR centers among all patients (odds ratio 0.60, 95% confidence interval 0.41–0.89, P=0.01) and among intermediate/high-risk patients (odds ratio 0.52, 95% confidence interval 0.32–0.85, P<0.01) but not among low-risk patients (odds ratio 0.82, 95% confidence interval 0.44–1.51, P=0.52).Conclusions:In-hospital TAVR availability was associated with better outcomes of SAVR among elderly patients. This association was statistically significant among intermediate/high-risk patients but not significant among low-risk patients.

Background: The aim of this study was to determine adequate indication for transcatheter aortic valve replacement (TAVR). We analyzed risk factors of surgical aortic valve replacement (SAVR) not only for mortality, but also for morbidity, including long hospital stay (≥90 days) and patient activity at discharge, in patients who underwent SAVR for aortic stenosis (AS). Methods and Results: Using the Japan Adult Cardiovascular Surgery Database (JCVSD), 13,961 patients with or without coronary artery bypass grafting who underwent elective SAVR for AS were identified from January 2008 to December 2012. The hospital mortality rate was 3.1%. The percentage of patients who had long hospital stay (≥90 days) and who had moderately or severely decompressed activity at discharge (modified Rankin scale ≥4) was 2.9% and 6.5%, respectively. Eleven and 20 preoperative predictors of hospital mortality and morbidity, respectively, including long hospital stay and compromised status at discharge, were identified. Based on these risk factors, the risk model predicted hospital mortality (area under the curve [AUC], 0.732) and morbidity (AUC, 0.694). Conclusions: Using JCVSD, a risk model of SAVR was developed for AS. This model can identify patients at high risk not only for mortality, but also for mortality and morbidity, including long hospital stay and status at discharge.

Background:Ventricular septal defect (VSD) after myocardial infarction (MI) is a rare but fatal complication. We report patients’ characteristics and operative outcomes after surgical repair of post-MI VSD using a national database of Japan.Methods and Results:This was a retrospective review of the Japan Adult Cardiovascular Surgery Database (JCVSD) to identify adults (age ≥18 years) who underwent surgical repair of post-MI VSD between 2008 and 2014. The primary outcome was operative death. We identified 1,397 patients (671 male [48%], 74.1±9.3 years old) undergoing surgical repair of post-MI VSD among 288,736 patients undergoing cardiac surgery enrolled in the JCVSD during the same period. Of these, 1,075 (77.0%) were supported preoperatively with an intra-aortic balloon pump. Surgical status was urgent in 391 (28.0%) and emergency/salvage in 731 (52.3%). Concomitant coronary artery bypass grafting was performed in 475 (34.0%). Overall 30-day and operative mortalities were 24.3% and 33.0%, respectively. Operative mortality varied according to surgical status: 15.6% in elective, 30.9% in urgent, and 40.6% in emergency/salvage cases. Multivariable analysis identified advanced age and emergency/salvage status as being strongly associated with increased odds of operative death.Conclusions:Post-MI VSD remains a devastating complication in Japan as well as in the USA and Europe.
