[Initial results of mitral valvuloplasty using the Physio-Carpentier-Edwards ring].
The Physio-Carpentier-Edwards ring is a new prosthetic ring developed to allow mitral annuloplasty associating remodelling and flexibility of the native mitral annulus. The object of this study was to assess the feasibility and reliability of mitral valvuloplasty with the Physio ring. Between December 1992 and October 1995, 100 patients with an average age of 56.8 years suffering from mitral insufficiency underwent mitral valvuloplasty with a Physio ring. The mitral insufficiency was degenerative in 94% of cases. The degree of regurgitation was scored 3+ or 4/+4/+ in 94 patients. Mitral valve prolapse was observed in 83 patients. Mitral reconstruction was undertaken using Carpentier's techniques. One patient died in the immediate postoperative period. Two patients were reoperated for valve replacement because of systolic anterior motion (SAM). One patient had SAM which regressed with medical treatment. There were no deaths after the hospital period. There were no late reoperations of thrombo-embolic complications. The average follow-up period was 19 +/- 8 months; 77 patients were followed up for over 1 year and all underwent control Doppler echocardiography. Sixty-one patients had no residual mitral insufficiency: 15 patients had grade 1/4 regurgitation and one patient had grade 2/4 regurgitation. The average mitral valve surface area was 2.8 +/- 0.3 cm2. The average left ventricular end diastolic volume decreased from 186 +/- 59 cm3 before surgery to 129 +/- 37 cm3 at the last control (p < 0.001). The authors conclude that the Physio ring enables reliable and effective mitral valvuloplasty with excellent short term results. The benefits of the flexibility of the Physio ring remain to be evaluated by a randomised trial.
