OBJECTIVES Ischaemic mitral valve regurgitation is associated with a significant reduction in survival and its treatment in patients undergoing surgical ventricular reconstruction is usually associated with higher perioperative morbidity and mortality. We evaluated our 11-year experience in this cohort of patients. METHODS Between January 2000 and December 2010, a total of 282 patients underwent surgical ventricular reconstruction, of which 45 (16%) had concomitant mitral valve surgery. The data was retrospectively analyzed to identify variables that could predict early mortality. RESULTS Overall in-hospital mortality was 6.4% (n = 18), of which 5.1% (n = 12) occurred in patients undergoing surgical ventricular reconstruction and 13.3% (n = 6) in patients undergoing surgical ventricular reconstruction + mitral valve surgery (P = 0.05). Patients undergoing surgical ventricular reconstruction + mitral valve surgery had poorer LV function (P < 0.01) and advanced NYHA class IV symptoms (P = 0.02) compared with patients undergoing surgical ventricular reconstruction. These patients had a higher requirement for postoperative inotropic (P < 0.01) and IABP support (P < 0.01) and were more likely to suffer from low cardiac output syndrome (P < 0.01). In patients undergoing surgical ventricular reconstruction + mitral valve surgery, 34 patients had mitral valve repair and 11 patients had mitral valve replacement. The mortality was 17.6% (n = 6) vs 0% (P = 0.31) in the mitral valve repair vs mitral valve replacement groups, respectively. The cohort of patients undergoing surgical ventricular reconstruction + mitral valve repair had poorer LV function and more advanced symptoms. CONCLUSIONS Patients undergoing surgical ventricular reconstruction have excellent early outcomes. However, there are patients that are at an increased operative risk, such as those with concomitant ischaemic mitral regurgitation that might be better served with other surgical modalities, such as ventricular assist device or heart transplantation. The suggested algorithm based on current evidence provides a stepwise approach when dealing with patients with ischaemic mitral regurgitation ± left ventricular remodelling.

Surgical treatment for functional mitral regurgitation secondary to dilated cardiomyopathy: Current options and future trends

There is an increasing number of patients with mitral regurgitation secondary to dilated cardiomyopathy. Recent data suggest that mitral regurgitation (MR) can be surgically corrected in heart failure with symptomatic improvements and favourable reverse left ventricular remodeling. However, several questions remain to be answered, regarding the optimal management of functional mitral regurgitat...

Transventricular edge-to-edge repair of the mitral valve during surgical ventricular restoration: review of the literature.

BACKGROUND Mitral valve surgery for functional ischemic mitral regurgitation (MR) in high-risk patients, including those requiring multiple concomitant cardiac operations, carries a significant risk of morbidity and mortality. In patients undergoing surgical ventricular restoration, transventricular edge-to-edge repair provides an effective alternative to conventional mitral valve surgery. We r...

Right sided heart evaluation after successful mitral valve replacement.

Introduction: It is well-documented that right-sided heart dysfunction and significant tricuspid valve regurgitation (TVR) have adverse effects on patient outcomes after left-sided heart valve surgery. Therefore, the evaluation of right ventriclular (RV) function and TR severity in patients who had undergone mitral valve replacement (MVR), associated with/without concomitant su...

AIMS To evaluate the feasibility of papillary muscle shortening in a specific group of high risk patients with ischaemic mitral regurgitation undergoing mitral valve reconstruction. BACKGROUND From January 1996 to December 1997, 712 (10.1%) out of a total of 7042 open heart patients underwent mitral valve surgery in our hospital. Mitral valve reconstruction was performed in 408 of these patie...

Management of mitral regurgitation during left ventricular reconstruction for ischemic heart failure.

OBJECTIVE Remodeling of the left ventricle (LV) in ischemic cardiomyopathy frequently leads to functional mitral regurgitation (MR). The indication for correcting MR in patients undergoing LV reconstruction (LVR) is unclear. In this study, we evaluated our strategy of correcting MR≥grade 2+ by restrictive mitral annuloplasty (RMA) during LVR. METHODS We studied 92 consecutive patients (76 men...
