Population over 80 years who require surgery for degenerative aortic stenosis has largely increased in the past decades. We have compared short- and mid-term results for conventional aortic valve replacement (AVR) for calcific-degenerative aortic stenosis in older and younger than 80 years operated at our institution between April 2004 and December 2008. Predictors of mortality and major adverse cardio and cerebrovascular events (MACCEs) on the postoperative and follow-up period were determined through multivariable analysis. Four hundred and fifty-one patients were included in the study. Ninety-four (20.8%) were >or=80. Previous cardiac surgery [odds ratio (OR)=4.08, P=0.047], renal failure (OR=6.75, P<0.001), concomitant coronary artery bypass grafting (CABG) (OR=2.57, P=0.034), female sex (OR=2.49, P=0.047), and severe pulmonary hypertension (OR=3.68, P=0.024) were independent predictors of in-hospital mortality. In the follow-up, age >or=80 years [Hazard ratio (HR)=2.44, P=0.02], high blood pressure (HBP) (HR=5.2, P=0.025) and peripheral arterial disease (PAD) (HR=5.1, P<0.001) were independent predictors for late mortality. Only PAD (HR=3.55, P=0.014) and HBP (HR=8.24, P=0.04) were independent predictors for late cardiac mortality. Renal failure (OR=2.57, P=0.005), severe pulmonary hypertension (OR=3.49, P=0.005) and concomitant CABG (OR=2.49, P=0.002) were independent predictors for postoperative MACCEs. Diabetes mellitus (HR=2.03, P=0.033) and PAD (HR=2.3, P=0.041) were independent predictors for MACCEs in the follow-up. According to these data, we can conclude that conventional open AVR for degenerative aortic stenosis grants good early- and mid-term outcomes in octogenarians in our experience.
TAVR and SAVR have similar short and long-term all-cause mortality and risk of stroke among patients of moderate or high surgical risk. TAVR decreases the risk of major bleeding, acute kidney injury and improves haemodynamic performance compared with SAVR but increases the risk of vascular complications, the need for a pacemaker and residual aortic regurgitation.
SYNTAX Score was remarkably high among patients undergoing surgical off-pump myocardial revascularization at our institution. In this subset of patients, a higher SYNTAX Score was associated with a higher incidence of in-hospital and follow-up major adverse cardiac and cerebrovascular events after coronary artery bypass grafting, but not with early or late mortality.
Emergency conversion from off- to on-pump CABG dramatically worsens early and late outcomes. Previous percutaneous coronary intervention and atrial fibrillation increase the risk of conversion.
We report our short-term and mid-term results with sutureless repair of postinfarction subacute left ventricular free wall rupture (LVFWR). For this purpose, we evaluated the short-term and mid-term postoperative results assessed by clinical examination and echocardiography of all patients who underwent surgery for subacute LVFWR between January 2004 and January 2009. Twenty-one patients were operated. Direct suture repair of LVFWR was carried out in only one patient. In all other cases we used a pericardial patch with biological glue. Early mortality was 19% (n=4). The median duration of follow-up was 17.3 months (interquartile range, 5-38.7), with a 13-month survival of 76%. Follow-up echocardiography showed no constriction associated with the rupture zone in any patient. According to our early experience, sutureless LVFWR repair is safe, effective and reproducible, and offers acceptable morbidity and mortality during follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
