Herein is presented the case of an 83-year-old male patient in cardiogenic shock with acute aortic regurgitation that occurred six years after aortic valve replacement (AVR) with a 23 mm Trifecta™ valve. Prosthesis endocarditis was initially suspected because of a floating structure attached to the aortic valve that was visible on echocardiography. Emergency redo-AVR surgery was performed, but no signs of endocarditis were found intraoperatively. Hence, cusp tearing of the implanted bioprosthesis was considered to be the reason for the severe aortic regurgitation...

The Trifecta aortic valve has excellent hemodynamic performance as result of an expansive valve design with a bovine pericardial sheet externally mounted on a titanium stent. We report two cases of early Trifecta valve degeneration, both caused by partial rupture of one of the leaflet cusps three and four years post-implant. Post discharge, both patients had routinely performed echocardiography check-ups, without signs of valve failure. Transesophageal echocardiography performed while emergency hospital readmission due to severe dyspnea revealed transvalvular aortic regurgitation without signs of endocarditis...

Energy security, environmental concerns, and unstable oil prices have been the driving trifecta of demand for alternative fuels in the United States. The United States' dependence on energy resources, often from unstable oil-producing countries has created political insecurities and concerns. As we try to gain energy security, unconventional oil becomes more common, flooding the market, and causing the major downshift of the usual unstable oil prices. Meanwhile, consumption of fossil fuels and the consequent CO2 emissions have driven disruptions in the Earth's atmosphere and are recognized to be responsible for global climate change...

AIMS: Valve-in-Valve (ViV) procedure has become a valuable alternative for the treatment of failed surgical bioprostheses (BP) in high risk patients. However, in small BPs, the clinical outcomes have been suboptimal due to high post-procedural gradients. We aimed at examining the effect of size and position of the self-expanding transcatheter heart valve (THV) CoreValve on the hemodynamics of ViV within small BPs. METHODS AND RESULTS: Sizes 23 and 26 mm of the CoreValve were implanted in sizes 19 and 21 mm of 3 BP models: Trifecta, Mitroflow and Epic Supra...

OBJECTIVES: Robotic-assisted partial nephrectomy (RAPN) is preferred to radical nephrectomy because it guarantees superior functional outcomes in patients with small renal masses (RMs). Only a few studies so far have evaluated the feasibility of RAPN for the treatment of RM ≥4 cm. The aim of this study is to evaluate the safety and feasibility of RAPN based on a comparison of trifecta and pentafecta rates for RMs ≥4 cm. MATERIAL AND METHODS: We retrospectively analyzed prospectively collected data from an institutional database of patients undergoing RAPN from September 2013 to November 2016...
