Background:
Linear and endoventricular techniques of left ventricular (LV) reconstruction often utilise prosthetic material for epicardial reinforcement or endocardial patch. We report a technique of LV aneurysm repair using absorbable suture without prosthetic material.
Methods:
Between November 1999 and August 2004, 55 patients underwent linear LV reconstruction, for ischaemic cardiomyopathy, using only continuous 3/0 polydioxanone suture. Survival, functional class and echocardiographic outcomes are reported.
Results:
Fifty-two patients (mean age 64+/-10 years) were studied. There was no perioperative mortality and the Kaplan-Meier survival at five years was 81%. Fifty-one patients underwent postoperative follow up (mean 28 months) with echocardiography (mean 20 months). There were no recurrent aneurysms. The postoperative LV eccentricity index (EI) was 0.72 (CI 0.48-0.9). Mean LV ejection fraction increased from 0.33+/-0.09 preoperatively to 0.41+/-0.15 at late follow up (mean within patient change 0.08+/-0.15, p=0.003). Mean symptom class improved from 3.3+/-0.8 to 1.6+/-0.7 (mean within patient improvement 1.6+/-1.0, p<0.001). Mitral regurgitation of grade 2/4 was identified in six patients and grade 3/4 in one patient.
Conclusion:
Linear repair with absorbable suture material and without prosthetic material may be safely undertaken with good early and mid-term results.
