ABSTRACT
<p><b>BACKGROUND</b>Few studies have evaluated late clinical outcome of no-patch technique in patients with large left ventricular aneurysms. The objectives of this study were to evaluate a no-patch surgical technique to reconstruct the left ventricle in patients with left ventricular aneurysm and to assess early and late clinical outcomes.</p><p><b>METHODS</b>In 1995, we began using a no-patch technique in patients with dyskinetic left ventricular aneurysms. A total of 145 patients underwent left ventricular reconstruction with this technique and were followed up for (59 ± 29) months (range, 1 - 127 months). Risk factors for early mortality were analyzed by bivariate analyses. Cox's proportional hazards model was used to calculate risk factors for all-cause mortality and hospital readmission. Kaplan-Meier methodology was used to analyze late survival.</p><p><b>RESULTS</b>One week after operation, left ventricular end-diastolic diameter had decreased from (61 ± 8) mm to (55 ± 8) mm, and geometry of the left ventricle was restored to a more normal conical shape. Early mortality was 3% and late mortality 11%. Over a 5-year follow-up period, hospital readmission was 28%. One-, 5-, and 10-year survival estimates were 95% (95% confidence interval (CI) 91% - 99%), 86% (95%CI 78% - 94%), and 74% (95%CI 60% - 88%). Readmission-free survival at 1 and 5 years after operation was 87% (95%CI 81% - 93%) and 60% (95%CI 50% - 70%), respectively.</p><p><b>CONCLUSION</b>The no-patch technique for left ventricular reconstruction is an effective and simple procedure that can achieve satisfactory early and late clinical outcomes in patients with left ventricular aneurysms.</p>
