Key result
Sandwich technique via RV incision linked to ~76% fewer residual shunts versus the David-Komeda method.
Why the study?
The study aimed to compare the sandwich technique via right ventricle incision with the David-Komeda method for surgical repair of postinfarction ventricular septal perforation to evaluate outcomes and complications.

Does the sandwich technique via right ventricle incision improve outcomes compared to the David-Komeda method in patients with postinfarction ventricular septal perforation?
Absolute Event Rate: 20% vs 83%
p-value: p=0.001
The sandwich technique via right ventricle incision for postinfarction VSP significantly reduces the incidence of residual shunts and the need for re-operation compared to the David-Komeda method, though 30-day mortality remains similar.
Sandwich repair may reduce residual shunts after postinfarction VSP; Level 5 data leave open randomized confirmation before practice change.

Yamanaka et al. (2018) conducted a cohort in Postinfarction ventricular septal perforation (VSP) (n=27). Sandwich technique via right ventricle incision vs. David-Komeda method was evaluated on Postoperative residual shunt (VSP leak) (p=0.001). The sandwich technique via right ventricle incision significantly reduced the rate of postoperative residual shunt (20% vs 83%, p=0.001) and re-operation (0% vs 42%, p=0.006) compared to the David-Komeda method.
