Objective: Different techniques have been described to repair post myocardial infarction ventricular septal rupture (VSR), each method may result in residual shunting, bleeding, and post-operative mortality. The aim of this report is to describe early results of extended sandwich technique through right ventricle in 20 consecutive patients.
Patients and Methods: A retrospective, cross-sectional and descriptive study on 20 patients underwent surgery for myocardial infarction VSR by extended sandwich technique through right ventricle from 12/2018 to 3/2021 in Hanoi Heart Hospital.
Result: 20 consecutive patients (10 women and 10 men) with postinfarction ventricular septal rupture (mean age 72 years, range 48-84) underwent surgical repair for by extended sandwich technique performed through right ventricle from December 2018 to August 2021 in our institute. Reconstruction of the septum was performed by two patches according to the method described by Asai et al. The mean aortic clamp time was 101. The mean extracorporeal circulation time was 143 min. Postoperative intensive care unit (ICU) stay averaged 4 days (range, 1-10 days). There was 30% hospital mortality. 10% postoperative residual shunting was detected, and no patient needed reoperation for bleeding.
Conclusion: This method of extended sandwich technique through right ventricle was safe, simple, and it could be performed in acute phase of myocardial infarction.
