Background -Conscious sedation is used during transcatheter aortic valve replacement (TAVR) with limited evidence as to the safety and efficacy of this practice. Methods -The NCDR STS/ACC TVT Registry was used to characterize the anesthesia choice and clinical outcomes of all U.S. patients undergoing elective percutaneous transfemoral TAVR between April 1, 2014 and June 30, 2015. Raw and inverse probability of treatment weighted (IPTW) analyses were performed to compare general anesthesia patients with conscious sedation patients on an intention-to-treat basis for the primary outcome of in-hospital mortality, and secondary outcomes including 30-day mortality, in-hospital and 30-day death/stroke, procedural success, ICU and hospital length-of-stay, and rates of discharge to home...

BACKGROUND AND AIM: Concomitant endovascular stent grafting of the descending thoracic aorta during open repair for acute DeBakey I aortic dissection can be performed in patients with extensive dissection and malperfusion. We analyzed the effects of this strategy on distal aortic remodeling. METHODS: From 2006-2014, acute DeBakey I dissection patients without primary aortic arch tear undergoing open distal hemiarch reconstruction (Standard group) versus those undergoing hemiarch with descending thoracic aorta (DTA) thoracic endovascular aortic repair (TEVAR group) were retrospectively reviewed...

INTRODUCTION: We evaluated the safety profile of a central cardiopulmonary bypass (CPB) cannulation strategy for repair of extent I thoracoabdominal aortic aneurysms (TAAA) with chronic type B dissection in comparison to traditional peripheral CPB cannulation strategies. METHODS: Patients undergoing extent I TAAA repair for chronic type B dissection from 2002 to 2011 were retrospectively reviewed. Patients were grouped by their CPB cannulation strategy. Patients in Group I underwent central aortic cannulation (n = 28) through a left thoracotomy incision...

BACKGROUND: This study evaluated outcomes of elective aortic hemiarch reconstruction for aneurysmal disease in the elderly. METHODS: Patients undergoing elective aortic hemiarch reconstruction for aneurysmal disease at a single institution between 2009 and 2014 were retrospectively reviewed. Patients were stratified into nonelderly (aged less than 75 years) versus elderly (aged 75 years or more). Outcomes included operative mortality and morbidity. RESULTS: In all, 629 patients (95 elderly; 15%) were included...

OBJECTIVE: In patients presenting with aortic valvulopathy with concomitant ascending aortic aneurysm, surgical management of the sinus of Valsalva segment remains undefined, especially for moderately dilated aortic roots. In patients with this pathology undergoing aortic valve replacement with supracoronary ascending aorta replacement, we assessed the fate of the remnant preserved sinus of Valsalva segment stratified by aortic valve morphology and pathology. METHODS: From 2002 to 2015, 428 patients underwent elective aortic valve replacement with supracoronary ascending aorta replacement...

Aims: Limited data exist on the long-term outcome of patients (pts) with non-ischemic cardiomyopathy (NICM) and ventricular tachycardia (VT) refractory to conventional therapies undergoing surgical ablation (SA). We aimed to investigate the long-term survival and VT recurrence in NICM pts with VT refractory to radiofrequency catheter ablation (RFCA) who underwent SA. Methods and results: Consecutive pts with NICM and VT refractory to RFCA who underwent SA were included...

In transplantation, there is a critical need for noninvasive biomarker platforms for monitoring immunologic rejection. We hypothesized that transplanted tissues release donor-specific exosomes into recipient circulation and that the quantitation and profiling of donor intra-exosomal cargoes may constitute a biomarker platform for monitoring rejection. Here, we have tested this hypothesis in a human-into-mouse xenogeneic islet transplant model and validated the concept in clinical settings of islet and renal transplantation...

BACKGROUND: Extracellular microvesicles (EVs) are being increasingly studied for their diagnostic potential. We investigated the feasibility of studying the kinetics and tissue-specific profiles of pulmonary EVs in the context of ex vivo lung perfusion (EVLP) used for salvaging marginal lungs for transplantation. METHODS: Perfusate from six marginal donor lungs placed on EVLP was collected at the following time points: 0, 10, and 60 minutes after and after perfusate exchange with Steen Solution; 120 and 180 minutes...

BACKGROUND: In acute DeBakey I aortic dissection presenting with malperfusion syndromes, we assessed whether standard open repair with concomitant antegrade stent grafting (thoracic endovascular aneurysm repair; TEVAR) of the descending thoracic aorta (DTA) improves outcomes compared with standard repair alone. METHODS: From 2005 to 2012, 277 patients with acute DeBakey I dissection underwent emergent operation. Of these, 104 patients (37%) presenting with end-organ malperfusion were divided into those undergoing standard distal repair entailing transverse hemiarch replacement (Standard group, n = 65) versus standard repair with concomitant DTA TEVAR during circulatory arrest (TEVAR group, n = 39)...

BACKGROUND: When valve replacement is required in patients with end-stage renal disease (ESRD), it is not clear if mechanical or bioprosthetic valve selection is better. We compared outcomes between ESRD patients who underwent either mechanical or biologic valve replacements at our institution. METHODS: All patients with ESRD who underwent either mitral or aortic valve replacement from 2002 to 2014 at our institution were reviewed (n = 215; mechanical = 64, biological = 151)...

Transcatheter aortic valve replacement (TAVR) has been commercially approved in the United States for the treatment of high-risk and inoperable patients with severe symptomatic aortic stenosis. While TAVR has proven benefits with regard to survival and quality of life in studied populations, the procedure is also associated with several well-described complications including stroke, vascular injury, and paravalvular regurgitation. More infrequent complications are less well described. Here, we report the development of new ventricular septal defects after TAVR in 4 patients with left ventricular outflow tract calcification...

BACKGROUND: There remains concern that moderate hypothermic circulatory arrest (MHCA) with antegrade cerebral perfusion (ACP) may provide suboptimal distal organ protection compared with deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (RCP). We compared postoperative acute kidney injury (AKI) in in patients who underwent elective hemiarch repair with either DHCA/RCP or MHCA/ACP. METHODS: This was a retrospective review of all patients undergoing elective aortic hemiarch reconstruction for aneurysmal disease between 2009 and 2014...

BACKGROUND: In patients with a bicuspid aortic valve presenting with aortic insufficiency (AI) and root aneurysm, we assessed whether outcomes with primary cusp repair with root reimplantation were equivalent to the gold standard Bentall procedures. METHODS: From 2002 to 2014, 710 patients with bicuspid aortic valve underwent aortic root procedures. Of these, only patients presenting with noncalcified type I bicuspid aortic valve with AI (n = 165) were included to maintain anatomic and physiologic homogeneity between the groups...
