Background
Ventricular Septal Defect (VSD) is the most common type of congenital heart abnormality with perimembranous VSD accounting for around 70% of all VSD. Nowadays, transcatheter closure is the first choice for suitable pmVSD. However, there was no report about closing the large oval shaped VSD percutaneusly.
Case summary
A 34-year-old male with known VSD was referred for transcatheter closure after failed attempts in other hospital. Patient had been diagnosed with VSD at a young age, but he was lost to follow-up. He presented with shortness of breath due to heart failure and pulmonary hypertension. The initial measurement of the defect was 6-7 mm by TTE, TEE and LV angiography. However, re-measurement using TEE and 3D echocardiography revealed that the VSD is oval with diameters of 18 mm x 6 mm. Initially, device No. 12/14 was used, but it was dislodged on twice attempts. The operator then decided to upsize the device size to No. 16/18 which was successful. The patient's condition was good and 6 months follow-up after the procedure showed good outcomes without any residual defect nor arrythmia.
Discussion
In this study, we would like to highlight the rarety of large oval VSD that almost failed to be closed with the conventional mesurement with echocardiography and fluoroscopy. TEE especially 3D can be the new modality of choice which might be superior to fluoroscopy to decide the right device size in some cases such as oval shaped VSD.
