Abstract
PURPOSE: To evaluate our 10-year clinical experience of performing the Pacopexy procedure for left ventricular aneurysm (LVA). METHODS: Between January, 1998 and November, 2015, a cohort of 92 patients with LVA underwent surgery to reshape the left ventricle. Fifty-seven patients underwent the Dor procedure and 35 underwent the Pacopexy procedure to emphasize the conical shape, whereby patch placement followed an oblique trajectory between the left ventricular apex and the septum below the aortic valve. RESULTS: The early-mortality rate was 4.34% (4/92; n = 2 in each group). The 10-year survival rate was 70.4 ± 7.9% in the Pacopexy group vs 41.7 ± 7.2% in the Dor group (p < 0.05), and the rate of freedom from hospital re-admission for heart failure (HF) or cardiac death was 60.0 ± 8.6% vs 28.8 ± 6.8%, respectively (p < 0.05). The Dor procedure and left ventricular end systolic volume index (LVESVI) ≥ 60 ml/m2 were strongly and significantly associated with long-term mortality and hospital re-admission for HF. CONCLUSIONS: The Pacopexy procedure is a reproducible surgical option for the treatment of LVA. The improved configuration achieved by the Pacopexy procedure has resulted in good long-term survival and a high degree of freedom from re-admission for HF in patients with advanced LVA.
