A curious case of pulmonary hypertension in a child

Area of Science:

• Pediatric Cardiology
• Pulmonary Hypertension
• Cardiothoracic Surgery

Background:

• Pulmonary hypertension in children has diverse causes, some reversible.
• Idiopathic pulmonary hypertension is a diagnosis of exclusion.
• Prompt identification of treatable etiologies is essential.

Purpose of the Study:

• To report a rare case of pulmonary hypertension secondary to constrictive pericarditis in a child.
• To highlight the importance of considering reversible causes of pulmonary hypertension.

Main Methods:

• A 12-year-old boy with exertional dyspnea and fatigue was re-evaluated for presumed primary pulmonary hypertension.
• Diagnostic workup included a detailed clinical assessment and investigations leading to constrictive pericarditis diagnosis.
• The patient was referred for surgical management (pericardiectomy).

Main Results:

• Constrictive pericarditis was identified as the cause of severe pulmonary hypertension.
• The patient's symptoms were initially misattributed to idiopathic pulmonary hypertension.
• The diagnosis was confirmed, and surgical intervention was planned.

Conclusions:

• Constrictive pericarditis can present with severe pulmonary hypertension without typical congestive heart failure symptoms.
• This case underscores the need to exclude reversible causes before diagnosing idiopathic pulmonary hypertension.
• Thorough evaluation is critical for accurate diagnosis and management of pediatric pulmonary hypertension.
