Echocardiography in adult patients with PDA: A simplified approach

Area of Science:

• Cardiology
• Pediatric Cardiology
• Adult Congenital Heart Disease

Background:

• Patent ductus arteriosus (PDA) is a common congenital heart defect in neonates and children.
• A subset of patients with PDA remain undiagnosed into adulthood, presenting with diverse clinical manifestations.
• Adult PDA presentation, hemodynamics, and management are influenced by PDA size, shunt magnitude, and pulmonary vasculature status.

Purpose of the Study:

• To present a simplified approach for the echocardiographic assessment of adult PDA.
• To guide clinicians in evaluating the varied presentations of PDA in the adult population.
• To emphasize echocardiography's role in diagnosing and managing adult PDA.

Main Methods:

• Review of existing literature and clinical guidelines on adult PDA.
• Description of a simplified echocardiographic assessment protocol for adult PDA.
• Focus on key echocardiographic parameters for evaluating PDA hemodynamics and shunt magnitude.

Main Results:

• Echocardiography is the primary imaging modality for evaluating adult PDA.
• A structured echocardiographic approach can effectively diagnose and assess hemodynamic significance of adult PDA.
• Echocardiography is crucial for pre-procedural planning and post-procedural follow-up.

Conclusions:

• Undiagnosed adult PDA requires specific diagnostic and management strategies.
• Simplified echocardiographic assessment provides essential diagnostic and hemodynamic information for adult PDA.
• Echocardiography is a vital tool for managing adult patients with PDA.
