Chronic expanding intrapericardial hematoma mimicking ST elevation myocardial infarction: A case report.

INTRODUCTION AND IMPORTANCE: The pericardium shields the heart, with pericarditis and Tetralogy of Fallot (TOF) posing diagnostic challenges. CEIH, a rare post-TOF repair complication, demands recognition for effective management. CASE PRESENTATION: A 57-year-old male, post-TOF repair, presented with chest pain and hypotension. Diagnostic tests revealed CEIH with right ventricular strain. CLINICAL DISCUSSION: CEIH, though rare, warrants consideration in post-TOF repair patients with chest pain. Timely recognition and intervention are vital to prevent serious complications. CONCLUSION: Vigilance for CEIH in post-TOF repair patients experiencing chest pain is crucial for optimal management and improved outcomes.
