OBJECTIVES: The aim of this study was to evaluate the long-term performance of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) through longitudinal echocardiographic analysis. BACKGROUND: The long-term performance of the SAPIEN TAVR is not well-described. Therefore, we examined the hemodynamic and valvular profile of the SAPIEN TAVR over 5 years. METHODS: All patients receiving TAVR or SAVR with first post-implant (FPI) and 5-year echoes were analyzed for aortic valve (AV) peak velocity, AV mean gradient, AV area, peak left ventricular (LV) outflow tract and in-stent velocities, Doppler velocity index, aortic regurgitation (AR), LV mass index, stroke volume index, and cardiac index...

BACKGROUND: Neurological events and brain infarction after transcatheter aortic valve replacement (TAVR) are concerns which may be reduced with transcatheter embolic protection (TEP). OBJECTIVE: Evaluate the safety and efficacy of TEP during TAVR. METHODS: Nineteen centers randomized 363 patients undergoing TAVR to safety (n=123), device imaging (n=121), and control imaging (n=119). The primary safety endpoint was major adverse cardiac and cerebrovascular events (MACCE) at 30 days and the primary efficacy endpoint was reduction in new lesion volume in protected brain territories on MRI scans at 2-7 days...

When clinicians consider extracorporeal life support (ECLS) for acute respiratory distress syndrome (ARDS) patients with hemodynamic instability, both veno-arterial (VA) and veno-venous (VV) ECLS are therapeutic possibilities. We analyzed 17 patients with ARDS on inotropic or vasopressor support requiring ECLS for refractory hypoxemia. After implementing VV ECLS, pressor requirements (based on norepinephrine equivalents) were significantly lower in all patients (P = .0001 for overall comparison across time points)...

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: Although preoperative renal dysfunction (RD) is associated with increased mortality and morbidity after surgical aortic valve replacement, its impact on clinical outcomes after transcatheter aortic valve replacement (TAVR) is less defined. METHODS: TAVR patients in the PARTNER (Placement of Aortic Transcatheter Valves) trial with a calculable glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease equation were included. Patients were divided into three groups: GFR >60 mL/min (none/mild RD), GFR 31 to 60 mL/min (moderate RD), and GFR ≤30 mL/min (severe RD)...

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)...

BACKGROUND: Hybrid coronary revascularization (HCR) combines minimally invasive surgical coronary artery bypass grafting of the left anterior descending artery with percutaneous coronary intervention (PCI) of non-left anterior descending vessels. HCR is increasingly used to treat multivessel coronary artery disease that includes stenoses in the proximal left anterior descending artery and at least 1 other vessel, but its effectiveness has not been rigorously evaluated. OBJECTIVES: This National Institutes of Health-funded, multicenter, observational study was conducted to explore the characteristics and outcomes of patients undergoing clinically indicated HCR and multivessel PCI for hybrid-eligible coronary artery disease, to inform the design of a confirmatory comparative effectiveness trial...

IMPORTANCE: Low-flow (LF) severe aortic stenosis (AS) is an independent predictor of mortality in patients undergoing aortic valve replacement (AVR). Little is known about improvement in flow after AVR and its effects on survival. OBJECTIVE: To determine whether higher flow (left-ventricular stroke volume index [LVSVI]) after transcatheter AVR (TAVR) would indicate better clinical outcomes in this at-risk population. DESIGN, SETTING, AND PARTICIPANTS: A substudy analysis of data from the Placement of Aortic Transcatheter Valves (PARTNER) randomized clinical trial and continued-access registry was conducted...

REVIEW
Ibrahim Sultan, Joseph E Bavaria, Wilson Szeto
Open repair of the aortic arch remains the gold standard for aortic aneurysms and dissections. However, in elderly patients with comorbidities, and in patients where prolonged cardiopulmonary bypass time and circulatory arrest may pose a significant risk, hybrid techniques in repairing the aortic arch have become quite attractive. Hybrid arch surgery includes a combination of endovascular and open surgery that allows surgeons to operate on the arch in a safe and expeditious manner with potential decrease in morbidity and mortality...

BACKGROUND: In the initial PARTNER trial (Placement of Aortic Transcatheter Valves) of transcatheter aortic valve replacement for high-risk (HR) and inoperable patients, mortality at 1 year was 24% in HR and 31% in inoperable patients. A recent report of the 30-day outcomes with the low-profile SAPIEN 3 transcatheter aortic valve replacement system demonstrated very low rates of adverse events, but little is known about the longer-term outcomes with this device. METHODS: Between October 2013 and September 2014, 583 HR (65%) or inoperable (35%) patients were treated via the transfemoral (84%) or transapical/transaortic (16%) access route at 29 US sites...

BACKGROUND AND PURPOSE: Stroke is a potentially devastating complication of cardiac surgery. Identifying predictors of radiographic infarct may lead to improved stroke prevention for surgical patients. METHODS: We reviewed 129 postoperative brain magnetic resonance imagings from a prospective study of patients undergoing surgical aortic valve replacement. Acute infarcts were classified as watershed or embolic using prespecified criteria. RESULTS: Acute infarct on magnetic resonance imaging was seen in 79 of 129 patients (61%), and interrater reliability for stroke pathogenesis was high (κ=0...
