Prosthetic Ring Choice in Secondary Mitral Regurgitation,r geometry. Secondary regurgitation is due to left ventricular pathology which often distorts the mitral annulus (Schmitto et al., Cardiol Rev 18(6):285–291, 2010). Bolling and colleagues first popularized mitral valve repair using an undersized mitral annuloplasty in the 1990s to address this patho

Papillary Muscle Relocation,and mitral annular dilatation, primarily along the posterior annulus. As the left ventricle dilates and the sphericity index increases, the papillary muscles are displaced laterally toward the apex and the interpapillary distance increases, resulting in distortion of the subvalvular apparatus and le

,The Role of the “Edge-to-Edge” in Mitral Valve Repair, an undersized annuloplasty. This procedure leads to symptomatic improvement and reverse left ventricular (LV) remodeling in a substantial proportion of patients. However, the failure rate of undersized annuloplasty is still high and is mainly due to inappropriate patient selection and to technical

Percutaneous Treatment in Mitral Valve Regurgitation, treatment of mitral regurgitation (MR). PMVI can correct MR by means of the direct or indirect reduction of mitral annular dilatation, or through intervention on the primary or secondary abnormalities of the mitral apparatus. Among PMVI techniques, the MitraClip system, which is able to reproduce t

Two- and Three- Dimensional Echocardiographic Imaging During Percutaneous Mitral Clip Procedure,ior mitral leaflet, a double orifice (Alfieri-like) mitral valve (MV) is created which decreases the annular dimension and MR severity (Wunderlich et al., Cardiol Clin 31:237–270, 2013). Echocardiography, mainly transesophageal echocardiography (TEE), plays a critical role in the procedure, not only

Right Ventricle and Functional Tricuspid Regurgitation: An Unpredictable Interaction, The RV appears triangular-shaped in a lateral viewed and crescent-shaped in a cross-section one. In normal conditions, the septum is concave toward the left ventricle (LV) in both systole and diastole and the RV volume is larger than the LV volume, Although its mass is one-third of the LV. The stri
