My daughter was identified to have a Subpulmonic vsd , 2mm. In the latest ECHO it is mentioned as Cristal VSD 2mm. Whether both are same?. She is of having average growth and all other parameters of the heart are normal except for
LV dialatation 20mm. She is advised for early VSD closure by OHS. Whether this is the only way out and how long it will
take to recover ?
A subpulmonary ventricular septal defect (VSD) and a supracristal VSD are in fact the same thing. This hole is located in the ventricular wall near the outflow tracts of the heart. Since the hole is close to both the aortic and pulmonic valves, the cardiologist must watch for prolapse of the aortic valve leaflet into the VSD over the course of time. Often the hole is small, as in this case 2 mm, sometimes because there is already aortic valve tissue in the defect. If the aortic valve becomes deformed and begins to leak, then surgery is indicated to close the hole and push the aortic valve away from that area. Given the small size of the VSD I would not expect your child to have any symptoms, but serial observation by your cardiologist is indicated with this form of VSD. If your doctors have already recommended surgery, then you need to clarify the indication for surgery with them.
