Sutureless repair for postinfarction left ventricular free wall rupture

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery
• Interventional Cardiology

Background:

• Left ventricular free wall rupture is a severe complication following acute myocardial infarction.
• Sutureless repair techniques have emerged as a potential surgical solution.
• The long-term outcomes and specific risks associated with sutureless repair require further investigation.

Purpose of the Study:

• To evaluate the outcomes of sutureless repair for left ventricular free wall rupture.
• To identify predictors of mortality and complications after this surgical procedure.

Main Methods:

• A retrospective study included 35 patients who underwent sutureless repair for left ventricular free wall rupture between 2001 and 2016.
• Sutureless repair utilized TachoComb or TachoSil patches without cardiopulmonary bypass.
• Patient data were analyzed for in-hospital mortality, re-rupture rates, long-term survival, and other complications.

Main Results:

• The in-hospital mortality rate was 17%, and re-rupture occurred in 17% of patients, often within 24 hours.
• Patients with the blow-out type rupture had a higher incidence of re-rupture.
• Overall survival rates at 1, 5, and 10 years were 71.4%, 68.6%, and 62.9%, respectively, with re-rupture being an independent predictor of decreased survival.

Conclusions:

• Sutureless repair using TachoComb/TachoSil patches is a feasible treatment for left ventricular free wall rupture.
• Caution is advised for the blow-out type rupture, as it is associated with a higher risk of re-rupture.
• Re-rupture significantly impacts long-term survival following sutureless repair.
