<P>Objective: To evaluate clinical and echocardiographic outcomes for the semi-flexible Carpentier-Edwards Physio and the rigid Classic mitral annuloplasty ring. </P><P>Methods: Ninety-six patients were randomized for either a Classic (n = 53) or a Physio (n = 43) ring from October 1995 through July 1997. Mean follow-up was 5.1 years (range .1-6.6). We included standard patient characteristics at baseline and during follow-up. Analyses were adjusted for age and gender, and for factors that differed across groups at baseline. In 2002, echocardiography was performed in 74% of the survivors. </P><P>Results: We found a 16% difference in mortality: 14% in the Physio group (n = 6) and 30% in the Classic group (n = 16) (adjusted P = .41). Life table analysis shows that the absolute risk of death after 30 months is lower in the Physio group. Intra-operative repair failure occurred in 3 patients (6%) of the Classic group, and in 4 (9%) of the Physio group, resulting in mitral valve replacement. Late failure occurred in 1 patient (2%) in the Classic group, and in 4 (9%) in the Physio group. At follow-up, left ventricular function did not differ across groups (ejection fraction 45% and 48% (adjusted P = .65)). The combined NYHA class III-IV had improved for the Classic group in 42% and for the Physio group in 34%. </P><P>Conclusion: Although the 16% difference in mortality did not reach statistical significance, it is considered clinically important. No differences in morbidity, valve function, and left ventricular function were found. Further research to explain the difference in mortality is required.</P>

Mitral Apparatus

In patients with functional mitral regurgitation, the placement of a sling encircling both papillary muscles in conjunction with mitral annuloplasty appears to be a rational approach for surgical correction, because it addresses both the mitral valve and the deformities of the subvalvular mitral apparatus. Reports in the literature that describe the utilization of this technique are few, and mainly involve a median sternotomy approach. The purpose of this communication is to describe the technical details of performing this procedure via a minimally invasive approach.

Anatomical Relationship

Functional mitral regurgitation affects a substantial proportion of patients with congestive heart failure due to myocardial infarction or dilated cardiomyopathy. Functional mitral regurgitation greatly increases morbidity and mortality. Surgical annuloplasty is the standard of care for symptomatic patients with moderate or severe functional mitral regurgitation; however, a large number of patients are refused surgery. Several percutaneous approaches have been developed to address the need for less invasive treatment of mitral annulus dilatation. Devices using coronary sinus to cinch the mitral annulus are relatively easy to use; however, a number of factors may limit their clinical application, such as suboptimal anatomical relationship between the coronary sinus and mitral annulus, risk of coronary artery compression, large variability in the coronary venous anatomy and conflict with other therapies such as ablation or cardiac resynchronisation. Direct mitral annuloplasty is anticipated to be more effective than the coronary sinus approaches; however, it has yet to prove its safety and efficacy in carefully designed clinical trials. The best candidates and the best timing for each percutaneous mitral annuloplasty therapy, whether direct or indirect, have yet to be identified.
