Summary of "Long Term Performance of Fresh Autologous Pericardium for Mitral Valve Leaflet Repair."

Glutaraldehyde-fixed autologous or bovine pericardial patches used for mitral valve leaflet reconstruction have been associated with late calcification. Fresh autologous pericardium (FAP) may be a durable alternative.

Long Term Performance of Fresh Autologous Pericardium for Mitral Valve Leaflet Repair (Commentary).

Midterm results of Mitral Valve Repair with Pericardial leaflet augmentation: A Single center experience.

In certain pathologies, mitral valve repair is complicated by a paucity of tissue caused by fibrosis or destruction. Utilization of autologous pericardium for leaflet augmentation may be the only opti...

Long-term results after reconstruction of a new annulus in heavily calcified mitral annulus.

In 2009 our group described a new surgical technique for patients with severe mitral valve calcification undergoing mitral valve surgery. This technique creates a new mitral annulus with plication of ...

Durability of Mitral Valve Bioprostheses: A meta-analysis of long-term follow-up studies.

Porcine and pericardial valves exhibited similar freedom from structural valve deterioration after aortic valve replacement. Limited data exists regarding their durability at long-term follow-up in th...

Early and long-term results of surgery for secondary mitral regurgitation with a damaged heart.

Surgery for secondary mitral regurgitation is still controversial, especially when the left ventricle is damaged. The Mitra Clip has been shown to be safe and effective for certain patient groups but ...

Cardiovalve Transfemoral Mitral Valve System

This study is to evaluate the safety and technical performance of the Cardiovalve Transfemoral Mitral Valve System with its associated procedure, to minimize mitral regurgitation. Data col...

Prognostic Impact of the Location of Mitral Valve Prolapse on the Long-term Results of Mitral Plasty

Mitral insufficiency (MI) accounts for 24% of adult valvulopathies and affects 7% of subjects older than 75 years. They are the second leading cause of valvulopathy in Europe. The most com...

To demonstrate that the Conveyor System can safely provide left ventricular access to deliver the SAPIEN 3 (Edwards Lifesciences, Irvine, California) transcatheter heart valve in patients ...

Left Ventricular Reverse Remodeling In Aortic Valve Replacement With Single Strip Pericardium Versus Mechanical Valve

Aortic stenosis is a commonly found heart disease, which often leads to mortality and morbidity. Valve replacement using mechanical prosthetic valve will have an expensive cost especially ...

Medical and Biotech [MESH] Definitions

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.

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.
