Percutaneous Mitral Valve Repair in Patients with Prior Cardiac Surgery.
Summary of "Percutaneous Mitral Valve Repair in Patients with Prior Cardiac Surgery."
Abstractâ€‚ Background and aim of the study: The safety of percutaneous mitral valve repair with the MitraClip system has been documented. However, few data are available on high-risk patients not amenable to surgery. The aim of this study was to evaluate the outcomes of patients with prior cardiac surgery undergoing MitraClip therapy (Abbott, Abbott Park, Chicago, IL, USA) for severe mitral regurgitation. Methods: We reported two cases of percutaneous treatment of severe mitral regurgitation performed in patients who had previously undergone cardiac surgery with the implantation of mechanical prosthetic aortic valve. Results: In both the reported cases a sustained reduction in mitral regurgitation severity was obtained at two-year follow-up, with a relevant improvement in terms of clinical status and quality of life. Conclusions: Percutaneous mitral valve repair using the MitraClip system represents a viable treatment choice for severe mitral regurgitation in high-risk patients who have previously undergone cardiac surgery.

Medical and Biotech [MESH] Definitions
Mitral Valve Annuloplasty
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.
Mitral Valve Prolapse
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.
Mitral Valve Insufficiency
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.
Cardiac Valve Annuloplasty
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annuli of HEART VALVES. 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.
Mitral Valve Stenosis
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.
