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 degenerative mitral regurgitation (DMR) which may increase repair durability. For the first time, this study reports mid-term results after MVR for DMR and FMR using a rigid three-dimensional ring (Profile 3D, Medtronic).

The fate of unrepaired tricuspid regurgitation (TR) after mitral repair (MVr) for degenerative mitral regurgitation (MR) remains highly debated. The objective of this study was to examine the progress...
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...
Most patients with severe degenerative mitral regurgitation (DMR) are likely to require surgery, but years can pass until there is a clear indication for it. The timing of mitral valve surgery for asy...
This study was performed to determine if strain can supplement the ability of left ventricular ejection fraction (LVEF) to predict post-op ventricular dysfunction in patients undergoing mitral valve (...
This study sought to evaluate the effects of the Carillon device on mitral regurgitation severity and left ventricular remodeling.
KALIOS is indicated for the surgical treatment of mitral regurgitation by mitral valve repair.It is intended for mitral valve repair using conventional open heart or minimally invasive tec...
This study aims to compare whether De Vega's Suture annuloplasty is equally effective in reducing the progression of Functional Tricuspid regurgitation as that claimed for Ring annuloplast...
The study evaluates the results of mitral valve repair with flexible band in comparison with rigid ring in patients undergoing mitral valve repair for degenerative mitral valve disease
Annuloplasty device for repair of mitral valve regurgitation with option to adjust device post implant off pump, to optimize correction of mitral regurgitation. Unlike conventional annulop...
The device is a dynamic annuloplasty ring/band that is able to be adjusted in order to correct for mitral regurgitation intraoperatively or postoperatively, off-pump.
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.
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.
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.
A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
