Characterization of 3-dimensional papillary muscle displacement in in vivo ovine models of ischemic/functional mitral regurgitation

Mitral Valve Repair for Mitral Valve Regurgitation with Papillary Muscle Displacement and Posterior Leaflet Prolapse

A case of abnormal chordae of the mitral valve (MV) associated with systolic anterior motion (SAM) is not commonly encountered in clinical practice. Here we report MV repair via the edge-to-edge technique in a 56-year-old male with MV regurgitation associated with papillary muscle displacement and posterior leaflet prolapse. Echocardiography revealed obstruction of the left ventricular outflow ...

Acute severe mitral regurgitation: consideration of papillary muscle architecture

We present a case of an individual who presented with acute severe mitral regurgitation in the setting of an inferior ST elevation myocardial infarction. Both transthoracic and transesophageal echocardiography demonstrated a posteriorly directed eccentric jet of severe mitral regurgitation with flail anterior mitral valve leaflet attached presumably to the anterior papillary muscle. Intraoperat...

Papillary muscle suspension concomitant with approximation for functional mitral regurgitation.

BACKGROUND Papillary muscle (PM) suspension concomitant with mitral annuloplasty and PM approximation (PMA) has been developed for functional mitral regurgitation (MR). In the present study, the early effect of PM suspension (PMS) on the postoperative mitral geometry and diastolic mitral tethering was investigated. METHODS AND RESULTS Subjects were 22 patients with left ventricular dysfunctio...

Papillary muscle infarction, mitral regurgitation, and long-term prognosis.

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
