Abstract

Percutaneous ventricular restoration is an established treatment that is used in left ventricle (LV) patients with anteroapical regional wall motion abnormality, dilated LV, systolic dysfunction after anterior myocardial infarction, and poor LV ejection fraction of heart failure. A ventricular partitioning device (VPD), which can be delivered percutaneously through the aortic valve, was placed at the apex of the LV. We aimed at improving the LV hemodynamics by isolating the dysfunctional apical region. Existing VPDs used in clinics are not recyclable. If the physician must extract the device owing to disease development, the patient must undergo thoracotomy. It is well known that thoracotomy is a high-risk operation. It may even cause patients to die. Therefore, we propose a recyclable left VPD that can be remove through a recovery snare after the device is implanted into the patient's ventricle. Such novel recyclable VPD could effectively avoid thoracotomy, thus resulting in favorable outcomes with reassuring safety.
