Post-Myocardial Infarction (MI) Left Ventricular Free Wall Rupture Managed Conservatively.

Left ventricular free wall rupture (LVFWR) is an uncommon but often fatal complication of acute myocardial infarction. LVFWR is managed with hemodynamic stabilization and is typically followed by surgical intervention with varying approaches depending on the type of LVFWR. A 78-year-old male with a history of coronary artery bypass graft (CABG) was admitted with ST-segment elevation myocardial infarction. Left heart catheterization showed complete occlusion of the saphenous vein graft to the 1st obtuse marginal artery. The patient was not a candidate for percutaneous coronary intervention or CABG. The patient later developed atrial fibrillation with a rapid ventricular response which was managed with beta blockers. Computed tomography pulmonary angiogram was done to rule out pulmonary embolus; however, it demonstrated findings of a lateral LVFWR. The patient was deemed a poor surgical candidate for cardiothoracic surgery, and the LVFWR was managed conservatively with metoprolol succinate and bed rest. He later required amiodarone and direct current cardioversion due to the recurrence of atrial fibrillation. Two months following the LVFWR, the patient remained stable with no apparent complications. In a certain subset of LVFWR patients, surgical management may not be possible given patient anatomy and other high-risk factors. In these cases, conservative management with bed rest and beta blockers and treatment of ventricular and atrial arrhythmias may be a viable therapeutic option.
