The Gasul Phenomenon Still Alive in the Developing World: A Case Report

BACKGROUND: In child, ventricular septal defect is the most prevalent congenital cardiac disease. Some ventricular septal defects have the potential for spontaneous closure. In poor nations closure based on indications may not be feasible. The patient's natural course may therefore be observed. The Gasul phenomenon, a right ventricular outflow obstruction, is one of the complications. CASE PRESENTATION: A 7-year-old child who had recurrent pneumonia, poor weight gain, and excessive sweating eventually had these symptoms go away. A large peri membranous ventricular septal defect and a small patent ductus arteriosus was detected on echocardiography during infancy. Later, the patient acquired a muscular ridge across the right ventricular outflow tract. Muscular ridge excision and closure of patent ductus arteriosus and ventricular septal defect were done. Patient was discharged in stable condition. CONCLUSION: Right ventricular outflow tract blockage can be avoided by performing early surgical closure of a ventricular septal defect.
