Accessory atrioventricular pathway in association with ventricular septal aneurysm

Area of Science:

• Cardiology
• Developmental Biology
• Medical Case Reports

Background:

• Ventricular pre-excitation, right ventricular dysplasia, and ventricular septal aneurysm are distinct cardiac conditions.
• The co-occurrence of these conditions is exceptionally rare, particularly in young adults.

Observation:

• A 23-year-old female patient presented with an unusual combination of cardiac anomalies.
• Diagnostic evaluations confirmed the presence of ventricular pre-excitation, right ventricular dysplasia, and a ventricular septal aneurysm.

Findings:

• Electrophysiological studies definitively identified an accessory pathway, a common finding in pre-excitation syndromes.
• The coexistence of dysplasia and aneurysm suggests a complex underlying developmental or genetic etiology.

Implications:

• This case highlights the importance of considering rare congenital heart disease combinations.
• Understanding the embryological basis may offer insights into novel therapeutic targets for complex cardiac malformations.
