The pulmonary valve's anomalies can lead to the obstruction of the right ventricle's outflow tract. This leads to the right ventricle's pressure overload, dilation, hypertrophy and eventually his malfunction. Balloon angioplasty or valve replacement surgery is indicated in cases of severe pulmonary stenosis. Often, the insertion of bioprosthetic pulmonary valves is required; however, after several years these patients often require a second surgery due to the valve's malcfunction. We report the case of a pregnant patient with a bioprosthetic pulmonary valve who required a ballon angioplasty due to this valve's stenosis.
RESUMEN: La coartación aórtica representa el 5-8% de todas las cardiopatías congénitas y se define como un estrechamiento de la luz aórtica a nivel del ligamento arterioso o debajo de este, clasificándose en preductal o posductal, y existen varias teorías que tratan de explicar su etiología, que aún sigue siendo poco clara. Puede diagnosticarse desde la infancia o en la edad adulta, debe sospecharse en todo paciente antes de los 30 años de edad que presente hipertensión arterial sistémica para poder brindar un tratamiento quirúrgico oportuno.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
