Background: Understanding morphological changes of ascending aorta, aortic arch and descending aorta with cardiac and respiratory motion is critical for planning of endovascular repair of thoracic aorta. The aim of this study was to determine the impact of the cardiac cycle on thoracic aortic geometry.
Methods: In this retrospective study, electrocardiogram-gated cardiac computed tomography from 116 patients who were evaluated for transcatheter aortic valve replacement were reviewed.
Background Blood pressure (BP) guidelines for patients with aortic stenosis or a history of aortic stenosis treated with aortic valve replacement (AVR) match those in the general population, but this extrapolation may not be warranted. Methods and Results Among patients enrolled in the Medtronic intermediate, high, and extreme risk trials, we included those with a transcatheter AVR (n=1794) or surgical AVR (n=1103) who were alive at 30 days. The associations between early (average of discharge and 30 day post-AVR) systolic BP (SBP) and diastolic BP (DBP) measurements and clinical outcomes between 30 days and 1 year were evaluated.

Pacemaker dependency and impact have not been methodically assessed in transcatheter aortic valve replacement trials. We report the incidence and predictors of pacemaker implantation and pacemaker dependency after transcatheter aortic valve replacement with the Lotus valve.

Background: Patients considered for transcatheter mitral valve replacement trials often screen-fail because of the perceived risk of LVOTO. In the Intrepid Global Pilot Study, assumed risk of LVOTO was based on computed tomography estimates of the neo-LVOT area computed at end-systole.

Background: Valve-in-valve transcatheter aortic valve replacement (TAVR) is an option when a surgical valve demonstrates deterioration and dysfunction. This study reports 3-year results following valve-in-valve with self-expanding TAVR.
Methods: The CoreValve US Expanded Use Study is a prospective, nonrandomized, single-arm study that evaluates safety and effectiveness of TAVR in extreme risk patients with symptomatic failed surgical biologic aortic valves.
Objectives: The study objectives were to evaluate the safety, efficacy, and hemodynamic performance of a novel stented bovine pericardial aortic valve bioprosthesis 2 years after implantation.
Methods: The PERIcardial SurGical AOrtic Valve ReplacemeNT Pivotal Trial enrolled patients with symptomatic moderate/severe aortic stenosis or regurgitation at centers in Canada, Europe, and the United States. We report the outcomes and hemodynamic performance in patients with up to 2 years of follow-up.

Cardiac tumors are rare. Most surgeons will encounter few primary cardiac tumors outside of myxomas. This article offers the authors' approach to simple and complex primary and secondary cardiac tumors.
View Article and Find Full Text PDFBackground: This study was conducted to determine the current nationwide trends and outcomes of reoperative surgical aortic valve replacement (SAVR) performed for a degenerated bioprosthesis.
Methods: Data from The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database were used. All patients who underwent isolated reoperative SAVR for a degenerated aortic bioprosthesis between January 2012 and December 2016 were included.
Background: For patients with severe aortic stenosis and coronary artery disease, the completely percutaneous approach to aortic valve replacement and revascularization has not been compared with the standard surgical approach.
Methods: The prospective SURTAVI trial (Safety and Efficiency Study of the Medtronic CoreValve System in the Treatment of Severe, Symptomatic Aortic Stenosis in Intermediate Risk Subjects Who Need Aortic Valve Replacement) enrolled intermediate-risk patients with severe aortic stenosis from 87 centers in the United States, Canada, and Europe between June 2012 and June 2016. Complex coronary artery disease with SYNTAX score (Synergy Between PCI with Taxus and Cardiac Surgery Trial) >22 was an exclusion criterion.

Patients with advanced valvular disease may be at high or prohibitive risk for surgical management. We describe a patient with previous mitral and tricuspid valve repair and recurrent admissions for New York Heart Association Class IV heart failure symptoms due to severe mitral stenosis and severe tricuspid regurgitation. Due to her comorbidities and two previous sternotomies, the patient was at high risk for surgery.

The 31-mm CoreValve and the next generation 34-mm Evolut R bioprostheses were designed to address the need for larger diameter aortic annuli. This analysis examined the clinical and hemodynamic outcomes following commercial transcatheter aortic valve implantation with the 31-mm CoreValve and 34-mm Evolut R in the Society of Thoracic Surgeons/the American College of Cardiology Transcatheter Valve Therapy Registry.
View Article and Find Full Text PDFTranscatheter aortic valve implantation (TAVI) is approved for treatment of symptomatic aortic stenosis in patients at increased risk for surgical valve replacement, but outcomes data in patients with severe native aortic regurgitation (AR) treated with TAVI remain limited. The objective of this analysis was to evaluate outcomes among patients identified in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapies Registry who underwent TAVI for native AR with a commercially available self-expanding valve system. From January 2014 to December 2017, 230 patients in the TVT Registry underwent TAVI for primary severe native AR using a commercially available self-expanding valve (n = 81, CoreValve; n = 149, Evolut R).

Objective: To compare TAVR with SAVR outcomes in patients at intermediate operative risk with prior CABG surgery.
