Complete atrioventricular block in Shone's syndrome

Area of Science:

• Cardiology
• Medical Case Reports
• Congenital Heart Disease

Background:

• Shone's syndrome is a rare congenital heart defect characterized by multiple left-sided obstructive lesions.
• Lev's disease, a specific form of supravalvular mitral stenosis, is less commonly associated with Shone's syndrome in adults.
• Complete atrioventricular (A-V) block is a serious cardiac conduction abnormality.

Observation:

• A rare case of an adult patient diagnosed with Shone's syndrome is presented.
• The patient exhibited clinical features suggestive of Lev's disease as a significant component of their condition.
• The development of complete A-V block was observed in this patient.

Findings:

• Lev's disease was identified as the predominant pathology contributing to the cardiac abnormalities in this adult Shone's syndrome case.
• The intricate relationship between these specific cardiac malformations and conduction system disease was elucidated.
• This case underscores the potential for Lev's disease to manifest significantly in adult presentations of Shone's syndrome.

Implications:

• This case expands the understanding of Shone's syndrome pathophysiology, particularly the role of Lev's disease in adult cardiac complications.
• It suggests the need for careful cardiac evaluation, including conduction system assessment, in adult patients with Shone's syndrome.
• Further research into the specific mechanisms linking Lev's disease and A-V block may inform management strategies for similar rare conditions.
