OBJECTIVE: To review intermediate to long term echocardiographic follow-up after mitral valve repair for mitral regurgitation.
DESIGN: Nonrandomized, retrospective and prospective observational study.
SETTING: Sacré-Coeur Hospital, University of Montreal, Montreal, Quebec.
PATIENTS: Echocardiographic findings in 37 patients (mean age 62.1 +/- 10 years) three to 197 months (median 45) after mitral valve repair were reviewed.
INTERVENTIONS: Preoperative data were collated from hospital records. Between October 1994 and March 1995, all patients had a clinical evaluation and a complete transthoracic echocardiogram done by a cardiologist.
RESULT: There was a significant reduction in the dimensions of the left-sided cavities compared with preoperative data. Left atrial diameter decreased from from 50.9 +/- 7.7 to 46.3 +/- 8.1 mm (P = 0.01), left ventricular end-diastolic diameter from 59.6 +/- 7.1 to 51.2 +/- 6.3 mm (P < 0.001) and left ventricular end-systolic diameter from 35.3 +/- 7.9 to 32.8 +/- 7.8 mm (P = 0.07). On colour Doppler echocardiography, nine patients had no mitral regurgitation, 25 had mitral regurgitation grade I to II/IV, and three had grade III/IV. The mean mitral valve gradient was 4.2 +/- 1.8 mmHg and the pressure half-time 121.9 +/- 48 ms. There was no difference in gradient, mitral valve area and mitral regurgitation in patients with degenerative (29) compared with rheumatic (five) mitral valve disease.
CONCLUSIONS: Mitral valve repair is highly effective in reducing mitral regurgitation in the long term and is associated with a reduction in the dimensions of the left atrium and the left ventricle. However, it leaves a mild degree of mitral valve obstruction.
