Left Ventricular Noncompaction Combined With Epinephrine-Secreted Pheochromocytoma Inducing Heart Failure

Area of Science:

• Cardiology
• Endocrinology
• Rare Diseases

Background:

• Pheochromocytomas are rare tumors secreting catecholamines, potentially causing cardiovascular complications.
• Left Ventricular Noncompaction (LVNC) is a rare congenital cardiomyopathy.
• Heart Failure (HF) can result from prolonged pressure overload and myocardial ischemia.

Observation:

• A patient presented with symptoms of heart failure (HF).
• The patient had a history of a catecholamine-secreting pheochromocytoma.
• Diagnostic evaluation revealed co-existing left ventricular noncompaction (LVNC).

Findings:

• The prolonged effects of pheochromocytoma-induced catecholamine excess led to myocardial ischemia, pressure overload, and hypertrophy, culminating in HF.
• This case is the first to report the simultaneous occurrence of LVNC and HF secondary to pheochromocytoma.
• LVNC may be associated with acute HF exacerbations triggered by pheochromocytoma.

Implications:

• This case expands the understanding of cardiovascular manifestations of pheochromocytoma.
• It suggests a potential link between pheochromocytoma, HF, and LVNC.
• Further research is warranted to explore the pathophysiology and clinical significance of this rare combination.
