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.

An Unexpected Case of Severe Arrhythmogenic Right Ventricular Cardiomyopathy.

We present the case of a previously healthy 14-year-old boy who experienced two episodes of lightheadedness while sitting under the sun. The patient did not experience syncope and denied experiencing any other symptoms. Moreover, he exhibited great functional capacity. An electrocardiogram showed T-wave inversions in leads V1 to V4. Subsequent echocardiogram and cardiac magnetic resonance imaging confirmed the diagnosis of arrhythmogenic cardiomyopathy with severe features. Arrhythmogenic cardiomyopathy is a disorder characterized by fibrofatty degeneration of the myocardium and is a common cause of sudden cardiac death. This case highlights the significance of early investigation in any child who presents with seemingly benign symptoms, as they may be indicative of a serious cardiac disease.

Coronary Artery Aneurysm: Its Evaluation in a 27-Year-Old Female Patient, Prognosis, and Suggested Treatment Strategies.

Coronary artery aneurysm (CAA) is characterized by a localized dilation of one or more of the coronary arteries with multiple etiologies, including congenital, acquired, or connected to auto-inflammatory diseases with multiple shapes and classifications. It is usually diagnosed incidentally during coronary imaging and can have variable clinical outcomes, ranging from asymptomatic to sudden cardiac death with a generally poor prognosis. Management of this condition faces a clinical dilemma due to the lack of clear guidelines or randomized trials. Treatment should be individualized based on symptoms, shape, and comorbidities. Herein, we present the case report of a 27-year-old female patient with no prior medical conditions. However, she presented with palpitations, and a compressive mass located over the right atrium was identified in the patient. After undergoing cardiac catheterization and coronary scanning, a giant aneurysm of the sinoatrial branch was detected with an aneurysmal left main that was retrieved surgically with good recovery and postoperative course.
