Mitral Valve Area During Exercise After Restrictive Mitral Valve Annuloplasty

Journal of the American College of Cardiology, 2015
Restrictive mitral valve annuloplasty (RMA) for secondary mitral regurgitation might cause functional mitral stenosis, yet its clinical impact and underlying pathophysiological mechanisms remain debated.The purpose of our study was to assess the hemodynamic and clinical impact of effective orifice area (EOA) after RMA and its relationship with ...

Pathological Remodeling of Mitral Valve Leaflets from Unphysiologic Leaflet Mechanics after Undersized Mitral Annuloplasty to Repair Ischemic Mitral Regurgitation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Undersized ring annuloplasty is a commonly used surgical repair for ischemic mitral regurgitation, in which annular downsizing corrects regurgitation, but alters valve geometry and elevates tissue stresses.

Mitral Valve Stenosis after Open Repair Surgery for Non-Rheumatic Mitral Valve Regurgitation: a Review

Frontiers in Cardiovascular Medicine, 2016
Mitral stenosis (MS) after mitral valve repair is a slowly progressive condition, usually detected many years after the index mitral valve surgery. It is defined as a transmitral pressure gradient (TMPG) of >5 mmHg or a mitral valve area (MVA)

Transcatheter Mitral Valve Replacement in Failed Bioprosthetic Valve, Ring, and Mitral Annular Calcification Associated Mitral Valve Disease Using Balloon Expandable Transcatheter Heart Valve

Methodist DeBakey Cardiovascular Journal, 2023
Transcatheter mitral valve replacement (TMVR) using the SAPIEN platform has been performed in failed bioprosthetic valves (valve-in-valve), surgical annuloplasty rings (valve-in-ring), and native valves with mitral annular calcification (MAC) (valve-in ...

Modelling mitral valvular dynamics–current trend and future directions [PDF]

, 2017
Dysfunction of mitral valve causes morbidity and premature mortality and remains a leading medical problem worldwide. Computational modelling aims to understand the biomechanics of human mitral valve and could lead to the development of new treatment ...

Comparison of flexible, open with semi-rigid, closed annuloplasty-rings for mitral valve repair

Journal of Cardiothoracic Surgery, 2021
Background Mitral regurgitation is a frequent valvular disease, with an increasing prevalence. We analysed the long-term outcomes of mitral valve repair procedures conducted over the last 10 years in our clinic using almost exclusively two different ...

Left atrial anomalous muscular band as incidental finding during video-assisted mitral surgery [PDF]

, 2018
Congenital fibromuscular bands have been described inleft ventricle or right atrium and have been diagnosed by echocardiography and CT scan. The first report of anomalous band in the left atrium was described in 1897 by Rollestone (1).

Mycobacterium goodii endocarditis following mitral valve ring annuloplasty [PDF]

Annals of Clinical Microbiology and Antimicrobials, 2017
Mycobacterium goodii is an infrequent human pathogen which has been implicated in prosthesis related infections and penetrating injuries. It is often initially misidentified as a gram-positive rod by clinical microbiologic laboratories and should be considered in the differential diagnosis.We describe here the second reported case of M.
