A new controversy is raising in cardiovascular surgery, whether or not the new generation transcatheter valves used for valve implantation are superior to surgical techniques used for traditional valve replacement. If such a debate is far from being an issue for mitral valve treatment, where minimal invasive, (robotic or video-assisted) mitral valve repair has become the gold standard for mitral valve treatment while transcatheter mitral valve solutions are lagging behind(1-4), there are many voices stating that the future of aortic valve treatment will mainly be transcatheter(5)...

BACKGROUND: Significant mitral regurgitation (MR) may reduce a pressure gradient of aortic stenosis (AS) by decreasing forward stroke volume. The study objective was to evaluate whether significant MR can cause inconsistency when assessing the severity of AS. METHODS: Among 5,355 patients diagnosed with AS from 2000 to 2015, 68 were retrospectively found to have concomitant significant (moderate or greater) MR and normal left ventricular ejection fractions in normal sinus rhythm (AS with MR)...

At the end of August 2017 the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) published new joint guidelines for the treatment of valvular heart disease. These guidelines incorporate the scientific progress since the last version of the guidelines published in 2012. This article reviews current guideline recommendations for antiplatelet and anticoagulative therapy after surgical/interventional treatment of the aortic and mitral valves and discusses the underlying scientific evidence...

Seismocardiogram, SCG, is the measure of precordial vibrations produced by the beating heart, from which cardiac mechanics may be explored on a beat-to-beat basis. We recently collected a large amount of SCG data (>69 recording hours) from an astronaut to investigate cardiac mechanics during sleep aboard the International Space Station and on Earth. SCG sleep recordings are characterized by a prolonged duration and wide heart rate swings, thus a specific algorithm was developed for their analysis. In this article we describe the new algorithm and its performance...

Data from the Japan cardiovascular surgery database from 2013 to 2014 were analyzed to demonstrate the mortality rate and choice of surgical procedures, especially concerning the selection of valve prosthesis for each valve position and patient age group, and the effects of preoperative complications on mortality and prosthetic valve selection. The proportion of each surgical procedure was compared for each patient age in the aortic, mitral, and tricuspid positions. The proportion of mechanical valve prostheses was 23...

In neonates requiring balloon aortic valvuloplasty, both anterograde and retrograde approaches are feasible. A recent comparison of these two approaches is lacking. A retrospective cohort study of neonates at a single center undergoing BAV from 9/00 to 7/14 was performed. Records were reviewed including pre- and post-intervention echocardiograms and catheterization data. Comparisons of acute efficacy and procedural safety were made based on type of approach utilized. Forty-two neonates underwent BAV. Eleven cases utilized exclusively an anterograde approach, while 31 included a retrograde approach (including 4 with both approaches used)...

Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV procedures for failing mitral bioprosthetic valves, 1 transfemoral procedure for failing pulmonary valve and 2 transfemoral ViV implantation for failing tricuspid bioprosthetic valves...

BACKGROUND: In patients undergoing aortic-valve or mitral-valve replacement, either a mechanical or biologic prosthesis is used. Biologic prostheses have been increasingly favored despite limited evidence supporting this practice. METHODS: We compared long-term mortality and rates of reoperation, stroke, and bleeding between inverse-probability-weighted cohorts of patients who underwent primary aortic-valve replacement or mitral-valve replacement with a mechanical or biologic prosthesis in California in the period from 1996 through 2013...

Importance: Identifying high-performing surgical valve centers with the best surgical outcomes is challenging. Hospital surgical volume is a frequently used surrogate for outcomes. However, its ability to distinguish low-performing and high-performing hospitals remains unknown. Objective: To examine the association of hospital procedure volume with hospital performance for aortic and mitral valve (MV) surgical procedures. Design, Setting, and Participants: Within an all-payer nationally representative data set of inpatient hospitalizations, this study identified 682 unique hospitals performing surgical aortic valve replacement (SAVR) and MV replacement and repair with or without coronary artery bypass grafting (CABG) between 2007 and 2011...

Patients with concomitant severe aortic stenosis (AS) and severe mitral stenosis (MS) with mitral annular calcification (MAC) constitute an elderly high-risk population with multiple baseline comorbidities that coexist even before they develop severe valvular dysfunction. Transcatheter mitral valve replacements (TMVR) offer an alternative option for high-risk patient with severe MS with MAC. A simultaneous transfemoral Transcatheter aortic valve replacement (TAVR) and transseptal TMVR is feasible and offers the least invasive approach of management...

BACKGROUND: Cardiac surgical units must balance trainee education with the duty to provide optimal patient care. This is particularly challenging with valvular surgery, given the lower volume and increased complexity of these procedures. The present meta-analysis was conducted to assess the impact of trainee operator status on clinical outcomes following valvular surgery. METHODS: Medline, Embase and CENTRAL databases were systematically searched for studies reporting clinical outcomes according to the training status of the primary operator (consultant or trainee)...
