Mid-term results of the floating stitch for systolic anterior motion in hypertrophic obstructive cardiomyopathy.

ABSTRACT:

Objective

Systolic anterior motion (SAM) is an important factor for hypertrophic obstructive cardiomyopathy (HOCM) patients with a hypertrophic interventricular septum. We developed the 'floating stitch technique' to relieve SAM and have used it since 2017. The mid-term results of the floating stitch technique are reported.

Methods

Ten consecutive HOCM patients (5 male, mean age 65.6 years) who underwent septal myectomy and the floating stitch technique from 2017 to 2022 were included. All patients underwent preoperative, pre-discharge, and annual follow-up echocardiographic evaluations. The median postoperative observation period was 3.5 (range 1.2-6.6) years.

Results

There were no cases of cutting or elongation of the floating stitch during the follow-up period. The
