BACKGROUND: Transcatheter valve implants currently draw their justification for use from reduction of perioperative risk. However, patient age and comorbidities are independent predictors of adverse outcome after aortic valve replacement, regardless of surgical approach. Therefore, it is unclear whether transapical aortic valve implantation really improves outcomes in high-risk patients. METHODS: ...

OBJECTIVES: Two-dimensional (2D) echocardiographic approaches are not sufficient to determine the origin of paravalvular leak (PVL) that occurs after prosthetic mitral valve replacement (MVR). In this study, we investigated the role of real-time three-dimensional transesophageal echocardiography (RT-3D TEE) in detecting the origin and size of PVL occurring after prosthetic MVR. ...

Paravalvular leakage following the atrioventricular valve replacement, though mostly harmless with insignificant morbidity, can result in heart failure and significant hemolysis that requires treatment. Reoperation is still the treatment of choice, but there is a high risk of recurrence, especially in patients with a history of endocarditis and/or those who ...
