SOUZA, Luiz Carlos Bento de et al. Surgical treatment of left ventricular aneuysm. Rev Bras Cir Cardiovasc [online]. 1987, vol.2, n.3, pp. 151-158. ISSN 0102-7638. http://dx.doi.org/10.1590/S0102-76381987000300001.
The authors report on 112 patients with ventricular aneurysms operated opon between January 1984 and March 1986. The late results were evaluated from a period of 8 months to 3 years of follow-up. The age ranged from 33 to 75 years, with 42% of patients between 51 and 60 years old; 87% were males. The most common pre-operative symptoms were: angina, congestive heart failure, and arrhythmias. The location of the left aneurysm was anteroapical in all patients. The number of arteries involved was as follows: 1 (22.3%) 25 cases; 2 (44.6%) 50 cases; 3 (27.6%) 31 cases, and 4 or more (5.3%) 6 cases. According to the regional ejection fraction, the patients were classified in 3 groups: good, 37 cases (33.0%); regular, 60 cases (53.5%) and bad, 15 cases (13.5%). The aneurysm was corrected basead on the modern concept of LV geometric reconstructing. In only 22 cases, isolated aneurysmectomy was performed and in the remaining 88 cases, additional procedures were performed. The hospital mortality rate was 7.1% (8 cases) corresponding to the following groups: good (2.7%) 1 case; regular (3.3%) 2 cases, and bad (33.3%) 5 cases. The late mortality rate was 8.6% (9 cases). The late follow-up of the surviving 95 patients showed that 50 were symptomatic, while 45 had no symptoms. The authors conclude that in the good and regular groups, the results were satisfactory; however, in the bad groups, the total mortality rate was high (40.0%).
