CLINICAL AND HAEMODYNAMIC STATUS AFTER RESECTION OF POSTINFARCTION LEFT VENTRICULAR ANEURYSM

This presentation describes our results of left ventricular aneurysm in 36 patients (average age 54.8±8.4 years, range 38 to 67 years) operated between 1977 and 1987. Associated procedures were performed in 21 (58%) including 20 coronary bypass grafting. Thirty-four hospital survivors were followed for 6 to 120 months (mean = 60.8±30.5 months). There were 2 hospital deaths (5.6%) and 2 late deaths (5.6%).
As for the immediate postoperative cardiac function after aneurysmectomy, HR, BP, PAP, PCWP, CI, LV SVI, LVSWI and PARI were measured by SG-catheter in comparsion with 45 cases which underwent a simple A-C bypass operation in the same period. As compared with the simple A-C bypass group, in the LVA group, both CI and LVSVI were relativeely low, while PAP and PCWP were significantly high from 6 to 48 hours after operation (p＜0.05-0.01), but there was no significant difference between the two groups at the third post-operative day.
Twenty-five patients were restudied between 6 and 12 months after aneurysmectomy. After aneurysmectomy a significant improvement was found in EF, LVEDVI, mean VC and LVDWS (p＜0.05-0.01), however, CI, LVEDP, Max dp/dt/p, LVSWI, LVSPI remained essentially unchanged and the regional shortening average in the analysis of left ventricular segmental wall motion was improved from 17.5±5.89% before aneurysmectomy to 20.6±5.99%. Haemodynamic studies during exercise revealed a significant smaller increase of the PAP and PCWP compared to the preoperative levels.
The mean grade in NYHA functional classification fell from 2.9 to 1.5. Only 15 patients (47%) returned to fulltime work. Improvement of quality of life was noticeable. The actuarial 5 year survival rate was 87.6% and the relative survival rate 93.9%
