[Myocardial revascularization with the gastroepiploic artery. The initial experience].

The internal mammary artery is widely recognized as the graft of choice for coronary artery bypass grafting at present. Alternative conduits have been investigated in order to find other adequate long-term grafts. The right gastroepiploic artery has been recently used as a graft to bypass distal coronary vessels. From November 1989 to April 1990 we have implanted this artery in 33 cases (32 in situ and one free grafts). The pedicled grafts were implanted in 17 patients in the main right coronary artery, in 13 we grafted the right distal branches, in one the left anterior descending, and the circumflex branch in one. The free graft was implanted in the first diagonal. Mean grafts per patient was of three in this series, with a mean of 2 arterial grafts per patient. One patient died in the early postoperative period. The remaining patients had an uncomplicated postoperative period. Thirteen patients underwent graft and coronary angiography. Direct or indirect graft patency was confirmed in all cases. The final important issue concerning the long-term patency of this graft will be solved in the future, but short-term patency rates of the right gastroepiploic artery can be anticipated when proper techniques are used.

[Infusion of fluids into the pulmonary artery in the treatment of acute myocardial infarction extending to the right ventricle. Evaluation of the method].

Seventeen patients with diagnosis of acute myocardial infarction with right ventricular extension were studied. All of them had evidence of contractile impairment of the right ventricle as shown by elevated filling pressure of the right ventricle, low systolic pulmonary pressure and low left ventricular filling pressure and cardiac output. These patients were treated with fluid infusion into the pulmonary artery besides other treatment measures for myocardial infarction in order to improve the filling pressure of the left ventricle and the cardiac output without stressing the right ventricle. The results obtained with this approach, which was maintained for 22 hours, showed a significant improvement in the stroke work indices of both ventricles and also in the cardiac output with a decrease in peripheral resistence without ever loading the ventricles. We analyze the physiological basis for using this procedure and also the complications that can occur. Our results show that the infusion of fluid into the pulmonary artery improves the hemodynamic situation of these patients and protects a damaged right ventricle.
