Shone complex, a rare heart condition, can lead to late-onset complete heart block (CHB) in adults. This study explores characteristics of patients with Shone complex who developed CHB later in life.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Electrophysiology
Background:
- Shone complex involves multiple obstructive left-sided cardiac lesions.
- Long-term outcomes for Shone complex are not well-documented due to its rarity.
- Late-onset complete heart block (CHB) is an unusual complication in Shone complex patients.
Purpose of the Study:
- To investigate potential associated characteristics in adult patients with Shone complex who develop late-onset CHB.
- To describe the clinical presentation and progression of CHB in this specific patient cohort.
Main Methods:
- Retrospective analysis of three adult cases (ages 31-59) with Shone complex.
- Review of clinical data and outcomes for patients who developed late CHB.
Main Results:
- Identified three adult patients with Shone complex who experienced late-onset CHB.
- Characterized the specific clinical profiles of these patients.
Conclusions:
- Late-onset CHB can occur in adults with Shone complex.
- Further research is needed to understand the underlying mechanisms and long-term implications.
