[Clinical and hemodynamic results after aneurysmectomy and coronary revascularization].
To assess the effects of left ventricular aneurysmectomy (l.v.a.) on left ventricular function (l.v.f.), a prospective clinical and hemodynamic study has been performed in nineteen patients (pts) operated on from 1979 to 1983. There where no operative deaths and only one late death during follow-up. A significant improvement in NYHA class was observed in 68% of the pts, 16% worsened, and the clinical status in the remaining 16% was unchanged. Hemodynamic data showed an increase in e.f. (33 +/- 12% to 43 +/- 10%; p less than 0.001), a reduction of the percentage of the abnormally contracting left ventricular segments (66 +/- 23% to 57 +/- 23%; p less than 0.05) and no significant changes of left ventricular end diastolic pressure. Revascularization index (nr. of bypassed vessels/nr. of stenotic vessels) and graft patency rate were low (0.57 and 0.72 respectively). No significant relation was noted between clinical and hemodynamic findings in the postoperative study. We conclude that l.v.a. is associated with an improvement of l.v.f. (mainly in e.f. and segmental wall contractility) and of clinical status of the pts but without a direct relation between these two parameters.
