[Aneurysm of the membranous septum. Angiocardiographic study]
Abstract:
Amongst 9000 patients on whom angiocardiograms had been carried out, a membranous septum aneurysm (MSA) was found in 47. In nine patients out of 27 the MSA could be demonstrated by sonography. The most common abnormalities accompanying this lesion were disturbances in rhythm and conduction (in 29 patients), ventricular septal defect in 29 and aortic insufficiency in 14. Complications included bacterial endocarditis in five patients (three with aortic insufficiency and two with sepsis lenta), aortic insufficiency (which was not of rheumatic or bacterial origin in three patients with conduction defects) and thirteen patients with abnormalities of cardiac rhythm with small VSDs.
Insights
Membranous septum aneurysms (MSA) are rare cardiac findings. This study details their prevalence, associated conditions like rhythm disturbances and ventricular septal defects, and complications such as endocarditis.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Membranous septum aneurysm (MSA) is a rare cardiac anomaly.
- Understanding its association with other cardiac defects and complications is crucial for patient management.
Purpose of the Study:
- To investigate the prevalence of membranous septum aneurysm (MSA) in patients undergoing angiocardiography.
- To identify common accompanying cardiac abnormalities and complications associated with MSA.
Main Methods:
- Retrospective analysis of 9000 angiocardiograms.
- Sonographic demonstration of MSA in a subset of patients.
- Review of associated cardiac conditions and clinical outcomes.
Main Results:
- 47 cases of MSA identified in 9000 patients.
- Sonography confirmed MSA in 9 out of 27 patients.
- Commonly associated findings included conduction disturbances (29 patients), ventricular septal defects (VSDs) (29 patients), and aortic insufficiency (14 patients).
- Complications included bacterial endocarditis (5 patients) and non-rheumatic/bacterial aortic insufficiency (3 patients).
Conclusions:
- Membranous septum aneurysm is an uncommon finding with significant associations.
- Conduction defects, VSDs, and aortic insufficiency are frequently observed alongside MSA.
- Potential complications like endocarditis warrant clinical attention.
