interventional management of a rare case of complex congenital heart disease in an adult patient: a case report

Congenital heart disease (chd), which accounts for about one-third of all congenital birth defects and affects about 1% of all live births worldwide, has had a stable incidence rate and decreased mortality rate since 1990. despite advances in fetal cardiac ultrasound examinations and routine pulse oximetry screening of newborns, a considerable proportion of patients with chd may still be missed until adulthood, leading to major morbidity and mortality due to physical limitations and reduced quality of life.we herein describe a 29-year-old woman who was mistaken as an inoperable case of chd and referred to our center with palpitation and exertional dyspnea. during workups, she was diagnosed with severe pulmonary hypertension associated with patent ductus arteriosus (pda), pre-ductal aortic coarctation, ventricular septal defect (vsd), and bicuspid aortic valve, all of which had been missed from infancy. after initial medical treatment for pulmonary hypertension, a simultaneous transcatheter approach was selected, whereby the pda was closed with an occluder device, and the coarctation was repaired simultaneously with a self-expanding stent. eight months later, her vsd was closed successfully via an interventional technique using a muscular vsd occluder device.this case highlights the significance of adult chd fellowship training. a cardiologist specialized in this field was able to properly diagnose and treat an adult with complex chd, which had been overlooked since infancy. as a result, the patient experienced complete relief from her symptoms and was saved from developing eisenmenger syndrome.
