Fungal bioprosthetic valve endocarditis is regarded as a rare, fatal disease. Severe aortic valve stenosis due to vegetation in bioprosthetic valves was also rare. Because biofilm formation is a factor related to persistent infection, the best outcomes for endocarditis are achieved in patients treated surgically with concomitant antifungal medicine.

Aortic stenosis is a prevalent disease that is treated with either mechanical or bioprosthetic valve replacement devices. However, these implants can experience problems with either functionality in the case of mechanical valves or long-term durability in the case of bioprosthetic valves. To enhance next generation prosthetic valves, such as biomimetic polymeric valves, an improved understanding of the native aortic valve leaflet structure and mechanical response is required to provide much needed benchmarks for future device development.

This report presents the case of a 66-year-old man with acute torrential aortic insufficiency after a Ross procedure 20 years earlier, a biologic aortic valve replacement 16 years earlier, and a transcatheter valve-in-valve 4 years earlier. He underwent third-time sternotomy, revealing that the pulmonary autograft was heavily calcified and frozen to the homograft. The previous transcatheter valve-in-valve was explanted.

Background: Continuous retrograde flow across the aortic valve from left ventricular assist device (LVAD) therapy can result in cusp damage and progressive aortic regurgitation, potentially triggering recurrent heart and multiorgan failure. The management of aortic regurgitation after LVAD implantation has not been well defined.
Methods: This study retrospectively reviewed the investigators' experience with the management of de novo aortic regurgitation requiring intervention in patients with continuous-flow LVAD.

Background: Comparative studies of outcomes between different biological mitral valve prostheses are scarce. This study compares the late clinical results of valve replacement with the Epic and Mosaic bioprostheses.
Methods: Patients undergoing isolated elective mitral valve replacement (MVR) between 2005 and 2019 were eligible for inclusion.

A 38-year-old woman underwent minimally invasive aortic valve replacement with a 21-mm Inspiris aortic valve and Cor-Knot for type 0 bicuspid valve and severe aortic stenosis. Postoperative transthoracic echocardiography was uneventful. Four months later, she experienced shortness of breath.
