Jatene correction of the ventricular geometry in postinfarction left ventricular aneurysm. Results of 62 operations.
Jatene correction of left ventricular aneurysm was performed on 62 patients (including 11 emergency operations) with mean age 60 years, 80% of them in NYHA class 3-4, with mean left ventricular ejection fraction c. 30%and mean left ventricular end-diastolic pressure c. 24 mm. Concomitant bypass grafting was performed in 58 cases (mean grafts per patient 3.7). Perioperative mortality was 12.9%. One patient had peroperative myocardial infarction. Postoperatively 13 patients had low cardiac output, requiring intra-aortic balloon pump in seven cases. There were no bleeding problems and 28 patients (45%) had no postoperative complications. The average hospital stay was 10.2 days. Left ventricular cavity size (echocardiography) showed significant reduction 1 week postoperatively, which was unchanged after 1 month. The left ventricular ejection fraction was significantly increased 1 month postoperatively. After follow-up averaging 15 months there was significant improvement in mean NYHA class. One patient underwent heart transplantation and died, but there were no other late deaths or cardiac-related complications. Jatene correction of left ventricular aneurysm is simple, carries acceptable mortality and low morbidity and significantly improves left ventricular function.
