Pulmonary valve fluttering in subpulmonic ventricular septal defect
American Heart Journal
|July 1, 1977
Summary
Subpulmonic ventricular septal defect can cause pulmonary valve fluttering, mimicking infundibular pulmonic stenosis on echocardiography. The underlying mechanism for this fluttering is likely the same in both conditions.
Area of Science:
- Cardiology
- Echocardiography
- Pediatric Cardiology
Background:
- Subpulmonic ventricular septal defect (SVSD) is a congenital heart anomaly.
- Pulmonary valve fluttering is an echocardiographic finding that can indicate various underlying pathologies.
Purpose of the Study:
- To present cases of SVSD with pulmonary valve fluttering.
- To compare the echocardiographic findings of SVSD with pulmonary valve fluttering to those of infundibular pulmonic stenosis.
Main Methods:
- Case series presentation.
- Echocardiographic imaging and analysis.
Main Results:
- Three patients with SVSD exhibited pulmonary valve fluttering on echocardiography.
- The observed echographic changes were indistinguishable from those typically seen in infundibular pulmonic stenosis.
Conclusions:
- Pulmonary valve fluttering in the context of SVSD presents echocardiographically similar to infundibular pulmonic stenosis.
- The mechanism causing fluttering in SVSD may be analogous to that in infundibular pulmonic stenosis.
