Surgical Outcome of Postinfarction Left Ventricular Free Wall Rupture.

Abstract

Left ventricular free wall rupture (LVFWR) is a rare and fatal complication after acute myocardial infarction. Early recognition and aggressive treatment are recommended. Between August 1999 and February 2023, 11 patients aged between 64 and 79 years developed LVFWR after acute myocardial infarction (mean interval, 3.5 days). Three patients had active bleeding (blowout-type LVFWR), and the other 8 patients experienced the oozing or sealed state. Eight patients were treated using a sutureless technique with Teflon felt and glue, 2 patients were treated using the primary suture closure technique, and 1 was treated using both the primary suture and the sutureless technique with Teflon felt and glue. One patient died in the operating room as a result of bleeding. Cardiovascular stability and hemostasis were achieved in the other 10 patients. There were 3 early deaths (all 3 cases as a result of area bleeding; 1 was treated with primary suture, 2 with sutureless glue). Three patients received percutaneous coronary intervention before discharge. All 8 remaining patients survived and were discharged. Three patients were lost to follow-up. The follow-up period ranged from 2 to 97 months, with 4 patients exhibiting New York Heart Association class I symptoms and 1 exhibiting New York Heart Association class II symptoms. Optimal surgical treatment for postinfarction LVFWR remains controversial. The sutureless technique may be a promising strategy for treating postinfarction LVFWR.
