Abstract:
Background: Neochordoplasty and/or leaflet resection are reliable and reproducible mitral valve (MV) repair techniques for the treatment of chordal rupture with severe mitral regurgitation (MR). We developed a novel computational evaluation strategy to determine the biomechanical and physiologic characteristics of MV dynamics prior to and following potential MV repair techniques to optimize surgical planning for neochordoplasty or leaflet resection. Methods: Virtual MV models from patients with P2 chordal rupture and severe MR were created using 3D echocardiographic data (N=5). Virtual neochor

Abstract Background Good mid-term durability of mitral valve repair of bileaflet lesions has been reported; however, patients may develop failure during follow-up. This study assessed late outcomes and mechanisms of failure associated with mitral valve repair of bileaflet lesions. Methods Fifty-six patients (mean age 67 ± 12 years) underwent mitral valve repair of bileaflet lesions due to degenerative disease in 2011–2018. Mitral annuloplasty was added to all procedures except for 1 patient with annular calcification. Mitral valve lesions were identified by surgical inspection. Mean clinical a

Abstract:
Introduction: The posterior ventricular anchoring neochordal (PVAN) repair is a nonresectional, single-suture technique for correcting posterior leaflet prolapse. While this technique has demonstrated clinical efficacy, a possible limitation is the stability of the suture anchored into myocardium as opposed to the fibrous portion of a papillary muscle. Hypothesis: We hypothesize that the PVAN suture serves only to position the leaflet for coaptation, after which systolic forces will be distributed throughout the valve, resulting in low peak forces on the suture. Methods: A left heart simulator

Abstract:
Introduction: Reducing peak forces and stresses on the neochordae used to repair mitral valve prolapse, can inhibit their late failure, and increase repair durability. Restoring a larger shelf of leaflet coaptation at the time of repair, could reduce neochordae stresses and aid durability. Hypothesis: In this study, we hypothesized that using a slightly smaller annuloplasty ring can yield a higher systolic coaptation length, which in turn could reduce the neochordal forces/stresses. Methods: Pig MV (n=7) were excised and studied in a pulsatile left heart simulator ( Fig. A ), with P2 prolapse

Abstract:
Introduzione. Il prolasso isolato posteriore è la disfunzione patologica più frequente del prolasso mitralico degenerativo; tecniche chirurgiche conservative, consolidate e basate sull’impianto di corde artificiali, e strategie percutanee sono oggi disponibili. La plastica neocordale è meno invasiva delle resezione mitralica e consente di “rispettare anziché resecare” il lembo malato; tuttavia, al fine di ottenere risultati ripetibili e standarizzati, richiede notevole esperienza per la selezione intra-operatoria della configurazione neocordale più appropriata e la definizione della lunghezz
