Key result
The double-patch technique for repairing blow-out type left ventricular free wall rupture was safe and provided good circulatory status, allowing the patient to be successfully weaned from bypass.
Why the study?
Blow-out type left ventricular free wall rupture after acute myocardial infarction is life-threatening, and existing sutureless or direct closure techniques are sometimes inadequate.

The double-patch technique is a safe and effective surgical method for repairing blow-out type left ventricular free wall rupture after acute myocardial infarction without compromising left ventricular volume.
Case success with double-patch repair in post-MI rupture supports feasibility in select patients; leaves open validation in larger series.
Left ventricular free wall rupture (LVFWR) is one of the most serious complications of acute myocardial infarction (AMI). Particularly, blow-out type LVFWR, characterized by active bleeding, is life-threatening, with a high mortality rate of 49.2% to 71.4%.1,2 In such cases of active bleeding, the sutureless technique is sometimes inadequate for hemostasis. Moreover, rerupture can occur following direct closure. Thus, the direct closure technique is sometimes inadequate in patients with a blow-out type LVFWR.

Nakatsu et al. (2022) conducted a case report in Blow-out type left ventricular free wall rupture after acute myocardial infarction (n=1). Double-patch repair technique was evaluated on Successful repair and survival. The double-patch technique for repairing blow-out type left ventricular free wall rupture was safe and provided good circulatory status, allowing the patient to be successfully weaned from bypass.
