The optimal treatment in patients with severe aortic stenosis and small annulus (SAA) remains to be determined. This study aimed compare the hemodynamic clinical outcomes between transcatheter valve replacement (TAVR) surgical (SAVR) a SAA.
Abstract Background and Aims Surgical explantation of transcatheter heart valves (THVs) is rapidly increasing, but there are limited data on patients with THV-associated infective endocarditis (IE). This study aims to assess the outcomes undergoing THV explant for IE. Methods All who underwent between 2011 2022 from 44 sites in EXPLANT-TAVR registry were identified. Patients IE as reason compared those other mechanisms bioprosthetic valve dysfunction (BVD). Results A total 372 included....
Background— The effects of dual antiplatelet therapy with aspirin and clopidogrel on the progression native coronary artery disease after bypass grafting are unknown. Methods Results— In Clopidogrel After Surgery for Coronary Artery DiseasE (CASCADE) trial, a total 113 patients were randomized to receive plus or placebo 1 year grafting. this secondary analysis, 92 who underwent preoperative 1-year postoperative angiograms at 2 centers had each their stenoses graded serially by using 6...
No human physiological data exists on whether aspirin only is as effective warfarin plus in preventing cerebral microembolization the early postoperative period after bioprosthetic aortic valve replacement (bAVR).We prospectively enrolled 56 patients who had no other indication for oral anticoagulation, underwent bAVR and received, an open-label fashion, either daily (for INR 2.0-3.0) 81 mg of (n=28) or 325 (n=28). Cerebral was quantified at 4 hours (baseline) 1 month postoperatively, by...
Old age is a significant risk factor for perioperative morbidity and mortality following cardiac surgery optimal myocardial protection strategy should be sought in this group of patients. We, therefore, reviewed the data on 295 consecutive patients older than 75 years who underwent any surgical procedure. Microplegia was used 144 compared to 151 had standard 4:1 blood cardioplegia. Logistic regression analysis propensity matching balance differences between two groups. The microplegia...
The contribution of aortic annular and root disease in bicuspid valve (BAV) insufficiency remains unclear. We compared geometry between BAV stenosis (AI), before after repair. Patients presenting for surgery (n = 58) were with patients 58). Clinical transoesophageal echocardiographic data collected, including end-diastolic diameters the ventriculo-aortic junction (VAJ), root, sinotubular (STJ) ascending aorta (AA). AI younger more likely to be male (AS) patients. VAJ, STJ significantly...
Background— Vasculogenic cell–based therapy combined with tissue engineering is a promising revascularization approach targeted at patients advanced coronary artery disease, many of whom exhibit myocardial hibernation. However, to date, no experimental data have been available in this context; we therefore examined the biopolymer-supported delivery circulating angiogenic cells using clinically relevant swine model hibernating myocardium. Methods and Results— Twenty-five underwent placement...
