Transcatheter closure of a fenestration in intracardiac Fontan circulation.

We present a case of tricuspid atresia and the treatment that was used in a child now aged 12. The malformation was corrected at the age of five through intracardiac Fontan circulation. Later, the child developed a right-to-left shunt due to dehiscence in the intra-atrial conduit, causing significant desaturation.

Patent ductus arteriosus--neonatal intensive care unit registry.

Objectives: This study took place at the Neonatal Intensive Care Unit (NICU) of the Dr Daniel de Matos Maternity Hospital and evaluated the incidence of patent ductus arteriosus (PDA), the clinical evolution of the newborns affected, the treatment prescribed, and associated morbidity and mortality.

Methods: We carried out a retrospective medical chart review of newborns admitted to the NICU between January 2001 and December 2005.

Results: PDA was found in 69 newborns.

Percutaneous retrieval of foreign bodies from the cardiovascular system.

We report our experience of seven patients referred to our hospital with foreign bodies embolized in the cardiovascular system, namely fragmented catheters and devices used in interventional techniques, which were retrieved by a percutaneous approach. The patients' ages ranged from 2 to 29 years, with a mean age of 17. The majority (57%) were male.

Ectopic origin of the right coronary artery--case report.

Coronary artery anomalies can occur in isolation or in association with other congenital heart defects. Clinical presentation ranges from asymptomatic forms to sudden cardiac death. The authors report a case of anomalous origin of the right coronary artery from the left sinus of Valsalva, diagnosed with multidetector computed tomography coronary angiography.

Massive calcification of the mitral valve annulus in an adolescent with Marfan syndrome. A case report.

Marfan syndrome (MFS) is an inherited connective tissue disorder, transmitted as an autosomal dominant trait. Its phenotypic and clinical expression is variable and involves several body systems. The ocular, skeletal and cardiovascular systems are characteristically affected.

Treatment of aortic aneurysm with covered stent. Case report.

The authors present the case of a thirteen-year-old boy with aortic coarctation, which was surgically corrected at the age of 2.5 months. He subsequently developed recoarctation, which was treated with balloon dilatation.

Cardiac tumors in the pediatric age group--case reports.

We present two case reports of primary cardiac tumors diagnosed in the pediatric age group, with different clinical evolution and therapeutic approach.

Percutaneous embolization of a congenital aortocaval fistula--clinical case.

Congenital aortocaval fistulae are a rare cause of left-to-right shunt. In this clinical case, an 8-year-old child was referred by the family doctor for pediatric cardiology consultation after detection of a chest murmur. Cardiac auscultation revealed a continuous murmur, best heard on the left sternal edge and back.
