We describe rare cases of common arterial trunk (truncus arteriosus communis) with unbalanced atrioventricular septal defect, left ventricular hypoplasia, and restrictive ventricular septal defect. The embryology, hemodynamics, and the clinical implications of this complex combination are discussed.
We report a case of 2-year-old boy who presented late after PDA device embolization to descending aorta. He had mild obstruction with erosion of the intimal layer of descending aorta caused by the device that was successfully retrieved surgically with reconstruction of the aortic segment.
Preoperative 'base line' PAm:SAm and RR appear to be better predictors of postoperative outcome than other baseline parameters. Preoperative reactivity test had no significant role in predicting postoperative reversibility of PAH at mid-term.
Ventricular septal defects (VSDs) are among the most common congenital heart defects. These defects may be isolated, associated with other defects, or occur as an intrinsic component of some complex heart defects. There is wide variation in size and location of VSD. Echocardiography plays an important role in evaluation of anatomy, hemodynamic significance, and planning of management of VSDs. With the emerging trends in transcatheter closure of VSD, echocardiography plays a crucial role in decision-making and intra- and postprocedure evaluation. A stepwise approach of echocardiography is necessary for accurate evaluation and management of VSDs.
Incidence of congenital heart defects in Down syndrome varies from 40% to 60%. Atrioventricular septal defect is most common defect seen, followed by isolated Ventricular Septal Defect (VSD). Multiple defects can be found in 5% to 10% of Down syndrome babies. Such patient usually presents with Pulmonary Hypertension (PAH) early in life and can develop rapid progression. An infant with Down syndrome weighing 6.5 kg presented with recurrent lower respiratory tract infections. A Transthoracic echocardiogram showed 10 mm secundum Atrial Septal Defect (ASD), 5 mm peri membranous Ventricular Septal Defect (VSD) and 3.5 mm conical shaped Patent Ductus Arteriosus (PDA) with Pulmonary Arterial Hypertension (PAH). As all the defects were suitable for transcatheter closure, patient underwent successful device closure of VSD by 6/4 mm Amplatzer duct occluder II (ADO II) device, PDA closure by 6/4 mm Amplatzer duct occluder (ADO) device and ASD closure by 12 mm Amplatzer septal occluder device. PA pressures of patient reduced significantly after the procedure and possible post-operative morbidity was avoided by transcatheter intervention.
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.
