RESUMEN

The authors analyse the experience acquired for surgical treatment of endomyocardiofibrosis. Among the 15 patients submitted to the operation, nine had the biventricular form, four had the disease in the right ventricle and two only in the left ventricle. The surgery consisted of endocardioectomy of the ventricles (RV--04,LV--02, bilateral--08) and replacement of the diseased atrioventricular valves (mitral--02, tricuspid--06, mitral and tricuspid--07). In one patient there was severe obstruction of the anterior descending artery and a bypass was done. Three patients had associated rheumatic mitral stenosis. There was one early operative death and three late deaths (respectively 13.34 and 37 months later). Two patients required re-operation. The first one, 33 months later, to replace the mitral valve which had been preserved in the first procedure, and the second, 12 months later, who presented ventricular septal defect secondary to rupture of the weak septum. Of all the patients who underwent surgery, 11 survived and all, except one, have had a good course. The detailed analysis of this series permitted us to conclude that: 1st--the general use of the bidimensional echocardiography in high risk patients, allows early diagnosis in a greater number of them; 2nd, the surgery must be early to avoid cardiac and extracardiac injury due to the disease; 3rd--a low profile valve must be used; 4th--to this moment there have been no signs of recurrence; 5th--surgical treatment appears to improve the course of this terrible disease.

RESUMEN

This report summarizes the surgical experience and early results obtained at four surgical centers in the northeast and south of Brazil. From December 1977 to September 1986, 95 operations were performed on 93 patients, ages 11-59. Bilateral lesions occurred in 42 patients, right lesions in 39, and left lesions in 12. Ventricular decortication and removal of thrombi were performed in all. In right-sided lesions, the tricuspid valve was substituted by a bioprosthesis in 34 cases, and substituted by a tilting disk valve in 1 case. In 4 patients, the valve could be preserved. The left-sided lesions led to valve substition by a bioprosthesis in 11 cases, and preservation of the valve in 1. The bilateral lesions needed bioprosthesis in the mitral position in 37 patients, and a disk valve in 2. In these 39 instances, the valvular procedure was insertion of a tricuspid bioprosthesis. Three tricuspid and three mitral plasties were performed. The overall mortality was 20% (26.2% for bilateral lesions, 14.6% for the right-sided lesions, and 20% for the left-sided lesions). The main cause of death was low cardiac output. Aside from a variable degree of right and left ventricular failure, many other non-fatal complications clouded the postoperative course. Complete AV blocks occurred in 10 cases, with the need for permanent pacing in 7 survivors. The mortality and morbidity in the present series is in keeping with the results reported in current literature. Regarding the advanced stage of their patients' disease, the authors agree with the recommendation for earlier surgical intervention.

RESUMEN

We developed a new surgical technique to treat coarctation of the aorta. It consists of an aortoplasty in which the left subclavian artery is transected, opened longitudinally, and sutured to the coarctated segment so as to correct the narrowing and also maintain blood flow through the left upper limb.
