The University of Pennsylvania group, in a porcine model of ischemic mitral regurgitation (IMR), compared echocardiographic surface coaptation in two groups of pigs: Those undergoing MV repair with a flat semirigid annuloplasty ring vs. with a saddle-shaped rigid annuloplasty ring.

Twenty-five cardiac surgery trainees underwent randomization to learn TEE interpretation by either of two approaches: traditional teaching during cardiac surgery vs. simulation-based teaching via the Heartworks simulator.

This is a provocative study questioning the current practice of using blood pressure targets perioperatively to ensure adequate perfusion. Plasma levels of a brain-specific injury biomarker (GFAP) were measured in 121 patients undergoing cardiac surgery.

This clinical case describes the successful treatment of severe aortic stenosis in a patient whose aortic anatomy precluded the traditional TAo approach. A 10mm Dacron graft was anastomosed end-to-side to provide adequate distance between the aortic annulus and the sheath insertion site.

This video demonstrates several tips for the superior septal approach to mitral valve surgery.

The FDA approved Edwards' Sapien third generation transcatheter aortic valve, designed to limit paravalvular leakage by incorporating a skirt at the base of the valve. The approval was based on results of the PARTNER II S3 study, which demonstrated improved rates of paravalvular leakage at 30 days (<4%) compared to 10% to 20% rates for other valv

In this paper the authors report on the 2-year results of the randomized US pivotal trial for surgical and self-expanding percutaneous aortic prosthetic valves. The survival benefit observed at 1 year in the transcatheter group were sustained at two years.

Using propensity score matching techniques, outcomes and costs for robotic cardiac surgery were compared to open cardiac surgery using data from the Nationwide Inpatient Sample. Robotic surgery was more expensive ($39,030 vs $36,340) but was associated with a shorter length of stay (5 vs 6 days), lower mortality (1.0% vs 1.9%), and lower overall com

In this manuscript the authors report on data from the German Aortic Valve Registry (GARY) comprising 15964 transcatheter aortic valve replacement (TAVR) procedures performed from 2011 to 2013 evaluating severe vital complications (SVCs), technical complications of the procedures (TCOs), other complications, conversion to sternotomy and in-hospital d

In this open-access article, the authors describe their findings in a systematic review of transcatheter heart valve (THV) failures, comprising 70 articles and 87 individual cases. Unusual complications such as late embolization (mostly into the left ventricle) and prosthetic compression (exclusively in balloon expandable THVs) are described.
