Key result
Surgical repair successfully resolves post-STEMI VSD complicated by Impella malfunction.
Why the study?
Post-myocardial infarction ventricular septal defect is a rare but frequently fatal mechanical complication.
Case Report (n=1)
This case highlights the importance of maintaining a high index of suspicion for mechanical complications in late-presenting myocardial infarction, even after apparent stabilization with revascularization and mechanical circulatory support.
Alerts clinicians to Impella malfunction risk after post-MI VSD; leaves open optimal device strategy in mechanical complications.
Post–myocardial infarction ventricular septal defect (VSD) is a rare but frequently fatal mechanical complication. We report a 67-year-old man who presented approximately 48 hours after symptom onset with dyspnea and was diagnosed with an ST-segment elevation myocardial infarction. He underwent emergent percutaneous coronary intervention supported by Impella placement but subsequently developed a large ventricular septal defect two days later, complicated by Impella malfunction. The patient ultimately underwent successful surgical repair. This case highlights the importance of maintaining a high index of suspicion for mechanical complications in late-presenting myocardial infarction, even after apparent stabilization with revascularization and mechanical circulatory support.

Hossain et al. (2026) conducted a case report in ST-segment elevation myocardial infarction (n=1). Percutaneous coronary intervention with Impella placement and surgical repair was evaluated. A 67-year-old man with late-presenting STEMI developed a ventricular septal defect 2 days after PCI and Impella placement, complicated by Impella malfunction, and underwent successful surgical repair.
