Transthoracic delivery of large devices into the left ventricle through the right ventricle and interventricular septum: preclinical feasibility

摘要

BackgroundWe aim to deliver large appliances into the left ventricle through the right ventricle and across the interventricular septum. This transthoracic access route exploits immediate recoil of the septum, and lower transmyocardial pressure gradient across the right versus left ventricular free wall. The route may enhance safety and allow subxiphoid rather than intercostal traversal.
