Key result
The triple patch technique for repairing postinfarction ventricular septal rupture demonstrated a 30-day mortality rate of 21.4% and a postoperative residual shunt rate of 14.3%.
Why the study?
Postinfarction VSR repair remains challenging with high mortality, and late outcomes involving patients with a residual shunt after VSR repair are lacking.
Does the triple patch technique improve survival and reduce residual shunts in patients with postinfarction ventricular septal rupture?
Observational (n=42)
No
Does the triple patch technique improve survival and reduce residual shunts in patients with postinfarction ventricular septal rupture?
The triple patch technique for postinfarction ventricular septal rupture repair is a safe and simple method that yields acceptable early and late outcomes with a low rate of postoperative residual shunts.
Residual shunts after triple-patch VSR repair often stabilize or resolve in survivors; leaves open optimal management in larger prospective cohorts.
Postinfarction ventricular septal rupture (VSR) remains an important and life-threatening complication of myocardial infarction (MI). Although several techniques have improved surgical outcomes of postinfarction VSR, the treatment is still challenging with a high mortality rate. In addition, it is well known that a postoperative residual shunt after VSR repair is associated with poor outcomes; however, late outcomes involving patients with a residual shunt after VSR repair are lacking. This paper presents the early and late outcomes of patients who underwent the triple patch technique to repair a VSR and the usefulness in reducing a postoperative residual shunt. The main process of this technique is that the patch is gently placed on the myocardium with over and over suture and is firmly attached using glue. Therefore, the triple patch technique is simple and easy to perform, and is designed to minimize residual shunt and exclude infarcted myocardium. In the present keynote lecture, we describe our surgical technique and the results of VSR repair.

Okamoto et al. (2022) conducted an observational in Postinfarction ventricular septal rupture (n=42). Triple patch technique was evaluated on 30-day mortality. The triple patch technique for repairing postinfarction ventricular septal rupture demonstrated a 30-day mortality rate of 21.4% and a postoperative residual shunt rate of 14.3%.
