Congenital complete atrioventricular block and prolapsing mitral valve

Area of Science:

• Cardiology
• Clinical Medicine
• Congenital Heart Disease

Background:

• Congenital complete atrioventricular block is a rare condition affecting cardiac conduction.
• Mitral valve prolapse is a common valvular heart disease.
• Co-occurrence of these conditions can complicate diagnosis and management.

Observation:

• A 41-year-old woman presented with ventricular arrhythmias.
• Her symptoms were initially attributed solely to congenital complete atrioventricular block.
• Physical examination revealed clues suggestive of mitral valve prolapse.

Findings:

• The case highlights the coexistence of congenital complete atrioventricular block and prolapsing mitral valve.
• Ventricular arrhythmias were present in the patient.
• Diagnostic challenges arise when symptoms overlap between these conditions.

Implications:

• Emphasizes the critical role of thorough physical examination in diagnosing mitral valve prolapse.
• Suggests considering concomitant valvular abnormalities in patients with congenital heart defects.
• Underscores the need for comprehensive cardiac evaluation to avoid misdiagnosis.
