Very late outcomes for mitral valve replacement with the Carpentier-Edwards pericardial bioprosthesis: 25-year follow-up of 450 implantations.
The aim of the present study was to evaluate the very-long-term results of the Carpentier-Edwards pericardial bioprosthesis in the mitral position. ⋯ With a low rate of valve-related events at 20 years and, in particular, a low rate of structural valve deterioration, the Carpentier-Edwards PERIMOUNT pericardial bioprosthesis remains a reliable choice for a mitral tissue valve, especially in patients >60 years old.

Long-term outcomes of survival and freedom from reoperation on the aortic root or valve after surgery for acute ascending aorta dissection.
Limited long-term outcome data are available on survival and the need for aortic root or valve reoperation after surgery for acute ascending aorta dissection. We report our 42-year experience. ⋯ Operative morbidity and mortality rates are significant after repair of acute ascending aorta dissection. Aortic root surgery can be performed without an apparent increase in the prevalence of operative morbidity or mortality; however, patients remain at risk of subsequent aortic root or valve surgery.

Minimally invasive fibrillating mitral valve replacement for patients with advanced cardiomyopathy: a safe and effective approach to treat a complex problem.
The optimal management of mitral regurgitation (MR) in patients with cardiomyopathy has been controversial. Minimally invasive fibrillating mitral valve replacement (mini-MVR) might limit postoperative morbidity and mortality by minimizing recurrent MR. We hypothesized that mini-MVR with complete chordal sparing would offer low mortality and halt left ventricular (LV) remodeling in patients with severe cardiomyopathy and severe MR. ⋯ Our results have shown that mini-MVR is safe in patients with advanced cardiomyopathy and resulted in no recurrent MR, stabilization of the LVEF and LV dimensions, and a decrease in right ventricular systolic pressure. This mini-MVR technique can be used to address severe MR in patients with advanced cardiomyopathy.

Left atrial endocardial dysfunction and platelet activation in patients with atrial fibrillation and mitral stenosis.
This study demonstrated left atrial endocardial dysfunction and platelet activation in patients with atrial fibrillation and mitral stenosis. ⋯ No differences were observed in plasma levels of vWF and P-selectin between left atrial and peripheral venous blood. Over expression of vWF gene in LAA may contribute to increased plasma vWF levels. P-selectin and vWF together may play a role in thrombosis.
