An Off-Pump Repair Technique for Postinfarction Apical Left Ventricular Aneurysm

抄録

Purpose: The conventional surgical treatment for postinfarction left ventricular aneurysm (LVA) is open-heart repair with cardiopulmonary bypass. However, the risk of the open-heart surgery under cardiopulmonary bypass may result in an unacceptable risk for many patients with multiple comorbidities. Here, we reported a new off-pump repair technique for postinfarction apical LVA.

Methods: A new off-pump repair technique, circular banding and occlusion technique, was applied to repair the postinfarction apical LVA in 12 patients. Clinical data of all those 12 patients were retrospectively reviewed. Patients were followed up prospectively by direct interviews and echocardiographic examination.

Results: The new repair technique was successfully performed in all these 12 patients. Acute reduction of the LVA mouth diameter, the left ventricular (LV) end-diastolic volume and end-systolic volume, and an increase in the LV ejection fraction (EF) were immediately obtained after the repair. Patients had an uneventful postoperative course. They were in New York Heart Association class 1–2, and the LV volume and EF detected by echocardiography remained unchanged during an average 28.4 ± 9.9 months (range 13 to 45 months) follow-up.

Conclusions: Circular banding and occlusion is a simple, safe, and effective off-pump repair technique for postinfarction apical LVA. It can allow effective LV remodeling and improve heart function.
