Mitral valve (MV) annuloplasty has been the gold standard for treatment of functional MV regurgitation (MR). However, annuloplasty for functional MR may cause augmented posterior leaflet tethering which results in functional anterior prolapse. Herein we added papillary muscle heads focalization for such patients. All separated papillary muscle heads are sutured together and the roots of chordae at each papillary muscle are unifocalized on both sides. Stiches are positioned at same distances from corresponding leaflet edges to adjust the height of leaflet edges in each segment. This is a simple and effective technique to correct for functional anterior prolapse after annuloplasty.

The main pathophysiological factor of chronic ischemic mitral regurgitation (MR) is the outward displacement of the papillary muscles (PMs) leading to leaflet tethering. For this reason, papillary mus...
Initial studies have suggested the familial clustering of mitral valve prolapse, but most of them were either community based among unselected individuals or applied non-specific diagnostic criteria. ...
Surgical repair of concomitant functional moderate tricuspid valve (TV) regurgitation at the time of mitral valve (MV) surgery remains controversial.
Three-dimensional saddle-shaped annuloplasty rings have been shown to create a larger surface of leaflet coaptation in mitral valve repair (MVR) for functional mitral regurgitation (FMR) and degene...
The indications for mitral valve surgery in patients with advanced non-ischemic dilated cardiomyopathy and functional mitral regurgitation are still unclear. We reviewed our experience of mitral valve...
Recent publications show that an adjunctive subvalvular repair during mitral annuloplasty for secondary mitral regurgitation effective in preventing recurrent regurgitation. One of these p...
The purpose of this prospective, non-randomized, single-arm feasibility study is to evaluate safety and feasibility of the iCoapsys System in patients with functional mitral valve insuffic...
The investigators are interested in determining the best surgical technique to correct functional mitral regurgitation, as there is currently not one technique that is established to work ...
Prospective, observational, multi-center trial in which patients with mitral regurgitation sufficient to merit mitral valve repair will receive a surgical transvalvular, intra-annular Mitr...
This study evaluates the addition of transcatheter mitral valve repair with the MitraClip device to medical treatment in patients with heart failure and moderate functional mitral regurgit...
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
Abnormal protrusion or billowing of one or both of the leaflets of MITRAL VALVE into the LEFT ATRIUM during SYSTOLE. This allows the backflow of blood into left atrium leading to MITRAL VALVE INSUFFICIENCY; SYSTOLIC MURMURS; or CARDIAC ARRHYTHMIA.
Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
