Pheochromocytoma, a type of neuroendocrine tumor, can cause numerous symptoms and signs similar to those of other clinical conditions, with the classic triad being palpitations, headache, and diaphoresis. Patients with pheochromocytoma can present with various cardiac complications, including myocarditis, acute coronary syndromes, cardiomyopathy, heart failure, and arrhythmias. Here we report a case of pheochromocytoma that first presented with bidirectional ventricular tachycardia. The patient was initially diagnosed with acute viral myocarditis and was treated accordingly. A pheochromocytoma crisis with severe blood pressure fluctuation occurred after glucocorticoid administration, leading to further diagnostic work-up, which eventually revealed the adrenal pheochromocytoma.

Objectives: Sinusoidal communication (SC) is prevalent among Fontan candidates with pulmonary atresia with intact ventricular septum (PA/IVS), making it crucial in understanding its dynamics and potential impact on myocardial perfusion. This study aimed to assess the risk of myocardial ischemia in these patients.
Methods: Sixteen Fontan candidates with PA/IVS were included in this study.

Purpose: This study aims to determine the outcomes of maintaining antegrade pulmonary blood flow (APBF) during the bidirectional cavopulmonary shunt (BCPS) procedure in patients with single ventricle physiology undergoing staged palliative surgeries.
Methods: A systematic search of electronic databases was conducted and focused on studies comparing pulsatile BCPS (with APBF) with non-pulsatile BCPS (without APBF). Outcomes were categorized into early (post-BCPS) and late (pre-Fontan).

Background: Anatomic characterization of unidirectional accessory pathways (APs) is inherently limited to the localization of the downstream insertion site. The inability to define the full anatomic course of unidirectional pathways can limit the safety and effectiveness of ablation in the setting of complex pathways, slanted pathways, unstable catheter positioning at downstream insertions, or insertions near the conduction system.
Objective: We aimed to develop novel pacing maneuvers to localize upstream insertions of unidirectional APs.

Infective endocarditis in infants with congenital heart disease is exceedingly rare and thus, treatment guidelines and expected outcomes are understudied. We present a 3-month-old girl diagnosed with native tricuspid valve endocarditis at the time of her pre-Glenn cardiac catheterization. She had resultant tricuspid valve and right ventricular dysfunction.
