case_images: Transthoracic echocardiography showed a supramitral ring (intramitral variant) and parachute like asymmetric mitral valve leading to mitral inflow obstruction with a mean gradient of 12 mmHg between left atrium and left ventricle (LV) [Figure 1, Supplementary Video File 1], subaortic membrane with left ventricular outflow obstruction with peak and mean gradients of 40 and 20 mmHg, respectively [Figures 1b and 2b], a subaortic ventricular septal defect (VSD) with left to right shunt [Figure 2a, Supplementary Video Files 2 and 3].

case_images: Transthoracic echocardiography showed a supramitral ring (intramitral variant) and parachute like asymmetric mitral valve leading to mitral inflow obstruction with a mean gradient of 12 mmHg between left atrium and left ventricle (LV) [Figure 1, Supplementary Video File 1], subaortic membrane with left ventricular outflow obstruction with peak and mean gradients of 40 and 20 mmHg, respectively [Figures 1b and 2b], a subaortic ventricular septal defect (VSD) with left to right shunt [Figure 2a, Supplementary Video Files 2 and 3]. The color Doppler imaging showed retrograde flow in PA suggestive of patent ductus arteriosus (PDA) [Figure 2c, Supplementary Video File 4] and suprasternal view demonstrated PDA and postductal coarctation of the aorta. Continuous wave Doppler revealed peak Doppler gradient of 60 mmHg across coarctation of aorta [Figure 2d, Supplementary Video File 5].

case_images: Transthoracic echocardiography showed a supramitral ring (intramitral variant) and parachute like asymmetric mitral valve leading to mitral inflow obstruction with a mean gradient of 12 mmHg between left atrium and left ventricle (LV) [Figure 1, Supplementary Video File 1], subaortic membrane with left ventricular outflow obstruction with peak and mean gradients of 40 and 20 mmHg, respectively [Figures 1b and 2b], a subaortic ventricular septal defect (VSD) with left to right shunt [Figure 2a, Supplementary Video Files 2 and 3]. Computerized tomography demonstrated VSD, subvalvular aortic stenosis, PDA, and postductal coarctation of aorta [Figure 3].
