Urgent surgery for ventricular septal rupture complicating acute myocardial infarction.

Area of Science:

• Cardiology
• Cardiac Surgery

Background:

• Postinfarction ventricular septal rupture (VSR) has high mortality with medical management.
• Delayed surgical intervention leads to many deaths while awaiting operation.

Purpose of the Study:

• To evaluate the efficacy of an aggressive strategy involving urgent cardiac catheterization and surgery for postinfarction VSR.
• To compare outcomes of urgent surgical intervention versus traditional medical management.

Main Methods:

• A cohort of 22 patients with postinfarction VSR were treated with urgent cardiac catheterization and surgery (within 2 days of rupture).
• Intra-aortic balloon pump support was utilized in 19 of 20 surgically treated patients.
• Data on patient demographics, interventions, complications, and outcomes were collected.

Main Results:

• Sixty percent (12/20) of patients survived hospitalization with the urgent surgery approach.
• Younger age, higher cardiac index, and lower shunt ratio were associated with better surgical outcomes.
• Recurrent rupture and reoperation were significant challenges, necessitating refinement in surgical techniques.

Conclusions:

• Urgent surgical intervention for postinfarction VSR significantly improves near-term survival compared to medical management.
• Long-term survival for hospital survivors is favorable.
• The aggressive surgical strategy is recommended, with a focus on improving operative techniques to address early recurrent rupture.
