Subaortic Stenosis in Association with Patent Ductus Arteriosus in a Young Woman from the Andes Region
DOI: 10.36660/abcimg.20230089i
Background
Defects affecting the left ventricular outflow tract (LVOT) are considered major congenital heart defects accounting for 6 out of 10,000 live births. Subaortic stenosis accounts for approximately 1% of all congenital heart defects and 15% to 20% of all LVOT obstruction defects. Subaortic membrane stenosis (SMS) is the most common type of subaortic stenosis, although it is a rare condition scarcely reported in the medical literature., Previous studies have reported its association in some cases with other congenital heart defects such as ventricular septal defects and patent ductus arteriosus (PDA)., Its association with PDA is particularly rare, to the extent that a case series published in 2020 mentioned only 3 previous cases. The objective of this article is to report a case of SMS in association with PDA in a woman from the Andes region.
