Case ReportsIntraoperative Diagnosis of a Stuck Bioprosthetic Valve Leaflet Due to a Loop of Suture After Mitral Valve Replacement.
A stuck mechanical valve leaflet is a well-known cardiovascular complication; however, a stuck bioprosthetic valve is a rare but potentially fatal complication. Herein a case of stuck bioprosthetic mitral valve caused by a loop of suture, which was detected on intraoperative 3-dimensional (3D) transesophageal echocardiography immediately after cardiopulmonary bypass, is presented. Restricted motion of the 2 leaflets during diastole and incomplete coaptation during systole were observed clearly on 3D imaging. Thus, intraoperative 3D transesophageal echocardiography imaging is useful for detecting such complications immediately after cardiopulmonary bypass.

Observational StudyRight Ventricular Longitudinal Strain Predicts Low-Cardiac- Output Syndrome After Surgical Aortic Valve Replacement in Patients With Preserved and Mid-range Ejection Fraction.
The aim of this study was to analyze whether right ventricular free wall longitudinal strain (RVFWSL) could be a predictor of low-cardiac-output syndrome (LCOS) after surgical aortic valve replacement (SAVR) in patients with left ventricular ejection fraction ≥40%. ⋯ RVFWSL seems to be a predictor of LCOS in patients with severe aortic stenosis and LVEF ≥40% undergoing SAVR. RVFWSL less than -17.3% may identify patients at increased risk for LCOS.
