Impact of Initial Axillary Microaxial Flow Pump on Post-Myocardial Infarction Ventricular Septal Defect Management.

ABSTRACT:

Objectives

The mortality rate of ventricular septal defect (VSD) following acute myocardial infarction remains high. Mechanical circulatory support devices have been shown to facilitate delayed surgery and improve postoperative survival, although clear guidelines for device selection are lacking.

Methods

This study presents a retrospective cohort analysis of 18 patients with post-infarction VSD treated with microaxial flow pump (mAFP) from March 2017 to November 2024. Patients were divided into 2 groups: the percutaneous group utilized Impella 2.5 or CP (Abiomed, Danvers, MA, USA) and the axillary access group (Impella 5.0 or 5.5). Their clinical outcomes and early to midterm survival rates were analysed.

Results

The survival discharge rate was 31% (4 in 13 patients)
