Jt. Christenson et al., JATENE CORRECTION OF THE VENTRICULAR GEOMETRY IN POSTINFARCTION LEFT-VENTRICULAR ANEURYSM - RESULTS OF 62 OPERATIONS, Scandinavian journal of thoracic and cardiovascular surgery, 29(2), 1995, pp. 53-57
Jatene correction of left ventricular aneurysm was performed on 62 pat
ients (including 11 emergency operations) with mean age 60 years, 80%
of them in NYHA class 3-4, with mean left ventricular ejection fractio
n c. 30% and mean left ventricular end-diastolic pressure c. 24 mm. Co
ncomitant bypass grafting was performed in 58 cases (mean grafts per p
atient 3.7). Perioperative mortality was 12.9%. One patient had perope
rative myocardial infarction. Postoperatively 13 patients had low card
iac output, requiring intra-aortic balloon pump in seven cases. There
were no bleeding problems and 28 patients (45%) had no postoperative c
omplications. The average hospital stay was 10.2 days. Left ventricula
r cavity size (echocardiography) showed significant reduction 1 week p
ostoperatively, which was unchanged after 1 month. The left ventricula
r ejection fraction was significantly increased 1 month postoperativel
y. After follow-up averaging 15 months there was significant improveme
nt in mean NYHA class. One patient underwent heart transplantation and
died, but there were no other late deaths or cardiac-related complica
tions. Jatene correction of left ventricular aneurysm is simple, carri
es acceptable mortality and low morbidity and significantly improves l
eft ventricular function.
