Why the study?
Do phonocardiographic findings correlate with the severity of pulmonary vascular disease in patients with ventricular septal defect?
Do phonocardiographic findings correlate with the severity of pulmonary vascular disease in patients with ventricular septal defect?
Auscultatory features, particularly the characteristics of the systolic murmur, serve as reliable clinical indicators of pulmonary vascular disease severity in patients with ventricular septal defects.
