Hospital and surgeon surgical valvar volume and survival after multivalve cardiac surgery in Medicare beneficiaries.

Objective: Long-term outcomes after multivalve cardiac surgery remain underevaluated.

Methods: Medicare administrative claims from 2008 to 2019 identified beneficiaries undergoing multivalve surgery. Operative characteristics were doubly adjudicated using International Classification of Diseases and Current Procedural Technology codes.

Contemporary Outcomes of Isolated Tricuspid Valve Surgery.

Introduction: Isolated tricuspid valve (TV) surgery is uncommonly performed and has historically been associated with excessive operative mortality. We previously reported improved short-term outcomes at our center. Understanding contemporary outcomes of isolated TV surgery beyond the perioperative period is essential to properly benchmark outcomes of newer transcatheter interventions.

Outcomes of Isolated Tricuspid Valve Surgery Have Improved in the Modern Era.

Background: Surgery for isolated tricuspid valve (TV) disease remains relatively infrequent because of significant patient comorbidities and poor surgical outcomes. This study reviewed the experience with isolated TV surgery in the current era to determine whether outcomes have improved.

Methods: From 2007 through 2017, 685 TV operations were performed in a single institution, of which 95 (13.

Does method of sternal repair influence long-term outcome of postoperative mediastinitis?

Background: Post-sternotomy mediastinitis reduces survival after cardiac surgery, potentially further affected by details of mediastinal vascularized flap reconstruction. The aim of this study was to evaluate survival after different methods for sternal reconstruction in mediastinitis.

Methods: Two hundred twenty-two adult cardiac surgery patients with post-sternotomy mediastinitis were reviewed.

Reducing hospital morbidity and mortality following esophagectomy.

Background: Esophagogastrectomy (EG) is a formidable operation with significant morbidity and mortality rates. Risk factor analyses have been performed, but few studies have produced strategies that have improved operative results. This study was performed in order to identify prognostic variables that might be used to develop a strategy for optimizing outcomes after EG.

Real-time three-dimensional echocardiography to construct clinically ready, load-independent indices of myocardial contractile performance.

Background: Real-time 3-dimensional echocardiography (RT3DE) reliably determines intracardiac chamber volumes without left ventricular (LV) geometric assumptions, yet clinical assessment of contractile performance is often on the basis of potentially inaccurate, load-dependent indices such as ejection fraction.

Methods: In 6 chronically instrumented dogs, RT3DE estimated LV volumes at various loading conditions. Preload recruitable stroke work and end-systolic pressure-volume relationships were constructed.
