Background: Despite technical improvements over the years, interventional closure of persistent ductus arteriosus in infants remains a challenge. Objectives: To assess safety, efficacy, and follow up results of closure of symptomatic persistent ductus arteriosus in infants using the self-expanding and repositionable Amplatzer device. Setting: Queen Alia Heart Institute (QAHI), a tertiary cardia...

Patent foramen ovale (PFO) is an anatomical variant of the interatrial septum with an overall prevalence of 27% in autopsy studies. PFOs have a potential role in causation of stroke, platypneaorthodeoxia, decompression sickness, right to left shunt and migraine headaches. Data regarding percutaneous closure of PFO in low volume tertiary care centers is lacking. Retrospective review of 14 percut...

BACKGROUND We investigated the safety, feasibility and efficacy of the Occlutech devices for patent foramen ovale (PFO) and atrial septal defect (ASD) closure in a prospective trial. METHODS The retention discs of the PFO device (23 x 25 mm, 27 x 30 mm) are connected by a 3 mm waist in the center with only one right atrial side central pin. The left atrial disc is produced either with a singl...

BACKGROUND Percutaneous closure of the patent foramen ovale (PFO) is usually performed under x-ray in combination with ultrasound guidance. We tested the feasibility of applying magnetic resonance (MR) guidance for percutaneous closure of PFO in an animal model, thus avoiding the disadvantage of ionizing radiation. METHODS AND RESULTS Real-time MRI with radial or spiral k-space filling (15 fr...

We report the case of a 72-year-old woman diagnosed with ostium secundum atrial septal defect (OS-ASD) in an echocardiogram performed as part of the work-up for her high blood pressure. Over time, progressive dilation of the right ventricle was observed with progressive functional deterioration, indicating closure of the defect. Transesophageal echocardiography (TEE) confirmed an OS-ASD of 15×1...

A 57-year-old woman with a history of a complicated open cholecystectomy and side-to-side choledochoduodenostomy (CDD) 25 years previously was admitted to our hospital with cholangitis. She had undergone five endoscopic retrograde cholangiopancreatography (ERCP) procedures with stone and debris extractions in another hospital during the preceding 2 years. ERCP revealed apatent biliary sphincter...

background: the ductus arteriosus connects the main pulmonary trunk to the descending aorta. the incidence of isolated patent ductus arteriosus (pda) in full-term infants is about 1 in 2000. the amplatzer ductal occluder (ado) is recommended for pdas with sizes larger than 2 mm. in this procedure, we must confirm the ado position in pda by aortogram from the arterial line. the purpose of this s...
