The edge-to-edge technique was introduced into the surgical armamentarium of mitral valve repair in the early 1990s. From the beginning, it appeared to be an attractive approach because of its simplicity, reproducibility and effectiveness even in complex settings. Several institutions around the world adopted this surgical method in selected patients with mitral regurgitation due to different c...
Redo Mitral Valve Surgery Via a Right Thoracotomy with Heart-Lung Machine: Presentation of Two Cases
The rate of redo surgeries are increasing on account of previously performed coronary artery bypass graft surgeries, aortic/ mitral valve replacement surgeries due to valve stenosis/ regurgitation, mitral valve repair for ischemic mitral regurgitation, the aging in the population, mechanical valve thrombosis and wearing out of the mechanical valves.Resternotomy, anterolateral right thoracotomy ...
INTRODUCTION Degenerative mitral regurgitation is currently the most frequent indication for mitral valve repair. AIM To visualize and assess the mid-term results of mitral valve repair with neochordae implantation, using computed tomography angiography (CTA) imaging. MATERIAL AND METHODS The CTA with ECG gating and without modulation was applied in 10 patients to assess the results of a mi...
BACKGROUND The gold-standard treatment of severe mitral regurgitation (MR) due to degenerative disease is valve repair, which is surgically performed with either a leaflet resection or leaflet preservation approach. Recent data suggest that functional mitral stenosis (MS) may occur following valve repair using a leaflet resection strategy, which adversely affects patient prognosis. A randomised...
Background Cardiac MRI has been shown to be the gold standard for noninvasive assessment of myocardial fibrosis. The extent of fibrosis has been associated with worse outcomes in patients undergoing CABG surgery. The presence of fibrosis and associated clinical features of patients with chronic mitral regurgitation undergoing mitral valve repair have not been described. The objective of this st...
n engl j med 361;23 nejm.org december 3, 2009 2261 This Journal feature begins with a case vignette that includes a therapeutic recommendation. A discussion of the clinical problem and the mechanism of benefit of this form of therapy follows. Major clinical studies, the clinical use of this therapy, and potential adverse effects are reviewed. Relevant formal guidelines, if they exist, are prese...
BACKGROUND Urgent or emergent status is often associated with increased risk among cardiac operations. The objective of this study was to analyze outcomes and cost differences in patients undergoing elective versus urgent or emergent mitral valve replacement (MVR) and repair operations. METHODS From 2003 to 2008, 1,477 patients underwent isolated, primary mitral valve (MV) operations at 11 di...
BACKGROUND In a randomized trial comparing mitral-valve repair with mitral-valve replacement in patients with severe ischemic mitral regurgitation, we found no significant difference in the left ventricular end-systolic volume index (LVESVI), survival, or adverse events at 1 year after surgery. However, patients in the repair group had significantly more recurrences of moderate or severe mitral...
BACKGROUND Ischemic mitral regurgitation is associated with increased mortality and morbidity. For surgical patients with moderate regurgitation, the benefits of adding mitral-valve repair to coronary-artery bypass grafting (CABG) are uncertain. METHODS We randomly assigned 301 patients with moderate ischemic mitral regurgitation to CABG alone or CABG plus mitral-valve repair (combined proced...
