The risk of the Ross procedure continues to be debated. We sought to determine the immediate outcomes of the Ross procedure in a large consecutive cohort that included patients undergoing reoperative cardiac surgery and/or concomitant cardiac procedures. ⋯ Excellent results can be achieved with the Ross procedure despite broader indications that include patients with previous sternotomy and with the need for concomitant procedures.

Trends in the traditional cardiothoracic surgery resident operative experience for cardiac cases: An analysis of Accreditation Council for Graduate Medical Education case logs.
To determine whether the changing cardiac landscape has affected traditional cardiothoracic surgery (CTS) resident case volume, particularly cardiac case volume. ⋯ The overall CTS resident operative experience has increased over the last several years, with cardiac cases increasing more slowly than thoracic cases. The analysis reveals that cardiac operative volume has been asymmetrically allocated to cardiac track residents, indicating a greater specialization of the tracks. Annual evaluation of CTS resident case volume will provide essential insight into the field.

Right ventricular undersizing is associated with increased 1-year mortality.
Right heart hemodynamic management is critical, because many post-heart transplantation (HTx) complications are related to right ventricular (RV) failure. However, current guidelines on size and sex matching rely primarily on weight matching, with recent literature using total ventricular mass (TVM), which places less emphasis on the impact of RV mass (RVM) matching. The aim of the present study was to analyze the relationship of RVM matching and survival after HTx. ⋯ RVM undersizing is an independent predictor for worse 1-year survival. Donors who are older and female have lower absolute predicted RVM and may be predisposed to RVM undersizing. RVM-undersized transplantation requires careful risk/benefit considerations.

Hemodynamic and transcriptomic studies suggest early left ventricular dysfunction in a preclinical model of severe mitral regurgitation.
Primary mitral regurgitation is a valvular lesion in which the left ventricular ejection fraction remains preserved for long periods, delaying a clinical trigger for mitral valve intervention. In this study, we sought to investigate whether adverse left ventricular remodeling occurs before a significant fall in ejection fraction and characterize these changes. ⋯ In this rodent model of mitral regurgitation, left ventricular ejection fraction was preserved for a long duration, yet rapid and severe left ventricular dilatation, and biological remodeling occurred before a clinically significant fall in ejection fraction.
