“…A gradients of > 50 mmHg, as diagnosed using a continuous-wave Doppler recording through the pulmonary valve indicate severe stenosis. This Doppler measurement represent peak instantaneous gradient which overestimates the peak-to-peak systolic catheterization gradient, presumably because of a pressure-recovery phenomenon [22]. In this child, the peak Doppler flow velocity of pulmonary stenotic jet 3.45 m/s as shown in Figure 9 and the gradient 48 mmHg suggest a moderate to severe pulmonary stenosis.…”

Rheumatic heart disease (RHD) is the most common cause of acquired heart disease in children and young adults worldwide and particularly developing countries continuing to experience a high incidence of this disease. The unexpected increase in the incidence of the disease in certain areas may explain the clinical and epidemiological characteristics of this disease. The key manifestation of RHD is the cardiac valvular abnormalities characterized principally by deforming the layered and avascular leaflet architecture due to inflammation and subsequent diffuse fibrosis. Mitral valve is mostly involved and pulmonary valve is rarely affected. Background of these case reports highlighted the increased incidence of rheumatic pulmonary valve disease in Thoothukudi region of India in Tamil Nadu state.

“…Therefore, the Doppler gradients are usually used in making a decision on the need for BAV. It was initially thought that peak instantaneous and/or mean Doppler gradients reflect the peak-to-peak catheter-measured gradients [22] but, because of factors related to pressure recovery phenomenon [23,24], the Doppler gradients are not necessarily accurate in predicting catheter gradients. I use an average of peak instantaneous and mean Doppler gradients as an alternative to calculate pressure recovery.…”

Balloon aortic valvuloplasty (BAV) provides an excellent alternative to surgical intervention and has become the preferred intervention for initial palliation for aortic stenosis in neonates, infants, children, adolescents, and young adults. The elderly patients with calcific aortic stenosis do not benefit from BAV. With the exception of neonates, most patients can be discharged home within 24-hours of the procedure. Although there is definitive evidence for pressure gradient relief immediately after as well as at follow-up and postponement of surgical intervention following BAV, the progression of aortic insufficiency at late follow up remain a major concern. In the neonatal population, severe aortic insufficiency may develop requiring surgical intervention. Despite these limitations, balloon aortic valvuloplasty is currently considered as therapeutic procedure of choice in the management of congenital aortic stenosis in the pediatric and young adult population. Careful follow-up to detect recurrence of stenosis and development of significant aortic insufficiency is recommended.

“…Here, the author encouraged another echocardiography colleague Dr. Gautam Singh to participate in such as study. The study was started, and data were secured; the data were presented at multiple scientific societies [40][41][42] but neither the author nor Dr. Singh completed the study manuscript at that time for publication. The following is a summary of the study and data:…”

The author’s contribution up to 1990 was reviewed in part I and the echo contributions from 1991 to 2020 will be reviewed in part II. These include defining the relationship between the quantity of shunt across the atrial septal defect (ASD) and the diameter of ASD by echo and angio on the one side and the stretched diameter of the ASD on the other; echocardiographic assessment of balloon-stretched diameter of secundum ASDs; development of echocardiographic predictors of accomplishment of percutaneous closure of ASDs with the buttoned device, highlighting limitations of echocardiography in comprehensive assessment of mixed type of total anomalous pulmonary venous connection; description of follow-up echocardiographic results of transcatheter closure of ASD with buttoned device; review of ultrasound studies; depiction of collaborative echocardiographic and Doppler studies; echocardiographic appraisal of the outcome of balloon pulmonary valvuloplasty; editorials; ventricular septal aneurysm causing pulmonary outflow tract obstruction in the morphologic left ventricle in corrected transposition of the great arteries; dependability of echocardiographic assessment of angiographic minimal diameter of the ductus; occurrence of supravalvular pulmonary artery stenosis after a Nuss procedure; echocardiographic assessment of neonates who were suspected of having heart disease; role of echocardiographic studies in the appraisal of patent ductus arteriosus in the premature babies; and the role of pressure recovery in explaining differences between simultaneously measured Doppler and cardiac catheterization pressure gradients across outflow tract stenotic lesions.
