Case ReportsMitral regurgitation following pericardiectomy for constrictive pericarditis.
Pericardiectomy is the only definitive treatment option for patients with constrictive pericarditis. We present the case of a 67-year-old man who developed new moderate to severe mitral regurgitation following phrenic nerve-to-phrenic nerve pericardiectomy for constrictive pericarditis. The severity of the regurgitation was followed up by serial echocardiography which showed improvement 19 days later and complete resolution at 9 months after surgery. Potential mechanisms explaining the evolution of this mitral valve dysfunction in the setting of pericardiectomy are postulated.

Freestyle stentless bioprosthesis for aortic valve therapy: 17-year clinical results.
Aortic valve replacement with stentless bioprostheses has been shown to produce lower aortic gradients than stented bioprostheses, thus facilitating left ventricular mass regression and preventing heart failure. We sought to determine the long-term results of stentless biological aortic valve replacement over a 17-year follow-up. ⋯ Long-term results after aortic valve replacement with stentless biological prostheses compare favorably with those obtained with stented bioprostheses.
