This review provides a comprehensive overview of subvalvular aortic stenosis, emphasizing echocardiography for diagnosis and surgery for treatment.
Highlights subvalvular aortic stenosis in adult congenital evaluations; leaves open optimal timing and long-term outcomes pending prospective data.
Subvalvular aortic stenosis (SAS) is one of the common adult congenital heart diseases, with a prevalence of 6.5%. It is usually diagnosed in the first decade of life. Echocardiography is the test of choice to diagnose SAS. Surgical correction is the best treatment modality, and the prognosis is usually excellent. In this review, we describe the pathophysiology, diagnosis, prognosis, and management of SAS with a focus on different pathophysiologic mechanisms, diagnostic approach, and prognosis of the disease by reviewing the current literature.
