We studied 8 patients with the subaortic ridge associated with ventricular septal defect (VSD) retrospectively. The type of VSD was perimembranous in 5 patients, subarterial in 2 and muscular in 1. Infundibular pulmonary stenosis (2), aortic regurgitation (2), pulmonary hypertension (2) and dextrocardia (1) were also associated problems. There was only one case in whom we could detect the ridge during the initial echocardiographic examination. In 7 cases the ridge was discovered through follow up examinations.
We confirmed the presence of a significant pressure gradient across the left ventricular outflow tract by catheterization in 3 cases who were older than 12 months, but no pressure gradients were detected m any patients less than 1 year old. In 5 of the 6 cases who underwent intracardiac repair, the ridge was not resected. A loud murmur remained in 2 patients and a pressure gradient in 3. Recently we resected the ridge in one patient with good results.
The clinical significance of a subaortic ridge with no pressure gradient is still unclear, although there is a potential for progression in some cases. Our current policy is to resect the ridge during surgical correction of the associated lesions and in the case of small VSD careful observations should be repeated using Doppler echocardiography.
