Сравнение поздних послеоперационных результатов пластической операции и замещения клапана сердца при митральной регургитации [Text] / Jun-ichi Hayashi [et al.] // Nihon kyobu geka gakkai zasshi = J. Jap. Assoc. Thorac. Surg. - 1992. - Vol. 40, N 10. - С. 46-50 . - ISSN 0369-4739
Аннотация: Between January 1980 and August 1991, 99 patients underwent operation for mitral valve regurgitation (MR). The ages of the patients ranged from 12 to 67 years, (49,4'+-'11,9 years), and there were 39 males and 60 females. Pathological cause of regurgitation, which was determined by intraoperative inspection and histological findings of excised leaflets, was rheumatic in 46, degenerative in 38, infective endocarditis in 9, ischemic in 4 and unknown in 2 patients. Cardiac rhythm was atrial fibrillation in 73, normal sinus rhythm in 24 and junctional rhythm in 2 patients. Our principles for valve repair were: 1) excision of responsible segment and repair for prolapsed leaflet due to torn chordae; 2) shortening of elongated chordae; 3) annuloplasty, and 4) repair of perforated leaflet. Finally, 19 patients endured plastic operation, and 80 patients underwent prosthetic valve replacement. The rate of plastic procedure was 62.5% (10/16) in degenerative MR with mural chordal lesions, 42.9% (3/7) in rheumatic MR without stenosis, 22.2% (2/9) in infective endocarditis and 100% (2/2) in MR with unknown etiology. Mitral valve repair was failed both in rheumatic MR associated with stenosis (39 patients) and in ischemic MR (4 patients). A ten-year survival rate after operation was 92.2'+-'3.1% in patients with valve replacement and 83.6'+-'10.0% with valve repair (N. S.), and a proportion of event-free survival in patients with valve replacement was similar to valve. Late postoperative cardiac catheterization revealed decreased left ventricular volume indices and increased left ventricular end-systolic stress/volume ratio in both groups compared to preoperative values, respectively. In conclusion, optimal selection of plastic procedures will offer satisfied postoperative results for non-ischemic mitral regurgitation without stenosis. Япония, Second Dep. of Surgery, Niigata Univ.
