background pulmonary arterial hypertension (pah) is a serious complication of unrepaired congenital left-to-right shunts. the final consequence is right ventricular (rv) systolic dysfunction and reversal of shunt. objectives the aim of this study was to evaluate the clinical course and paraclinical findings in a group of patients with pah associated with congenital heart disease (pah-chd). we a...

OBJECTIVE To determine if lower starting pulse fluoroscopy rates lead to lower overall radiation exposure without increasing complication rates or perceived procedure length or difficulty. SETTING The pediatric cardiac catheterization laboratory at University of Michigan Mott Children's Hospital. PATIENTS Pediatric patients with congenital heart disease. DESIGN/INTERVENTIONS We performed ...

Although the utility of diagnostic cardiac catheterization in the clinical setting has diminished over the last years, due to the emergence of noninvasive imaging modalities, such as echocardiography, magnetic resonance imaging and computed tomography, catheterization for diagnostic reasons still constitutes a valuable tool in certain parts in the workup of pediatric heart disease. As a result,...

BACKGROUND Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free di...
