Early systolic closure of the aortic valve
British Heart Journal
|October 1, 1980
Insights
Early systolic closure of the aortic valve is not specific to subvalvular aortic stenosis. This finding was observed in six patients with various heart conditions, not just subaortic stenosis.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Cardiac Imaging
Background:
- Early systolic closure of the aortic valve is a recognized echocardiographic finding.
- Its association with specific cardiac pathologies requires further elucidation.
Observation:
- Six pediatric patients presented with early systolic closure of the aortic valve.
- These patients exhibited diverse congenital and acquired heart conditions, including mitral regurgitation, double outlet right ventricle, left ventricular diverticulum, congestive cardiomyopathy, Eisenmenger ventricular septal defect, and aortic regurgitation with ascending aorta aneurysm.
Findings:
- None of the described patients had evidence of subaortic stenosis.
- Early systolic closure of the aortic valve was observed across a spectrum of cardiac anomalies.
Implications:
- Early systolic closure of the aortic valve is a non-specific echocardiographic sign.
- This finding should not be solely interpreted as indicative of subvalvular aortic stenosis, necessitating a comprehensive diagnostic approach.
Abstract:
Six patients with early systolic closure of the aortic valve are described with mitral regurgitation, double outlet right ventricle, left ventricular diverticulum, congestive cardiomyopathy, Eisenmenger ventricular septal defect, and aortic regurgitation with an aneurysmal ascending aorta, respectively. None had evidence of subaortic stenosis. Early sytolic closure of the aortic valve is thus not diagnostic of subvalvular aortic stenosis but is a non-specific finding.
