Abstract: INTRODUCTION AND IMPORTANCE: Congenital cardiac diverticula are rare malformations involving the myocardium, the endocardium, and occasionally the pericardium. They have variable presentations and are often incidental findings. CASE PRESENTATION: A 61-year-old man with no significant history presented worsening exertional dyspnea. Examination revealed obesity but was otherwise unremarkable. Initial tests were normal, but chest radiography showed cardiomegaly and ECG indicated diffuse microvoltage. Echocardiography revealed a large left ventricular diverticulum (7 × 8 cm) with a wide neck (4 cm) and severe dysfunction (EF 30 %). Coronary angiography confirmed normal coronary arteries. Despite intensive care, his condition deteriorated and required mechanical ventilation and vasoactive support. He underwent emergency surgery but succumbed intraoperatively. CLINICAL DISCUSSION: Although rare, congenital cardiac diverticula can cause severe complications, including heart failure and sudden death. Echocardiography is the key to diagnosis, with CT or MRI providing further characterization. Surgery is the preferred treatment for symptomatic cases, while asymptomatic patients require close follow-up. CONCLUSION: This case highlights the need for early diagnosis and timely intervention in congenital cardiac diverticula to prevent fatal outcomes.
