Cardiac CT angiography in children with congenital heart disease.

Cardiac imaging plays an important role in both congenital and acquired heart diseases. Cardiac computed tomography (angiography) cCT(A) is a non-invasive, increasingly popular, complementary modality to echocardiography in evaluation of congenital heart diseases (CHD) in children. Despite radiation exposure, cCT(A) is now commonly used for evaluation of the complex CHD, giving information of both intra-cardiac and extra-cardiac anatomy, coronary arteries, and vascular structures.

Transcoronary bone marrow-derived progenitor cells in a child with myocardial infarction: first pediatric experience.

Background: Recent advances in stem cell therapy to restore cardiac function have great promise for patients with congestive heart failure after myocardial infarction in an adult population.

Objective: We examined the benefits of bone marrow-derived progenitor cells treatment modality for the pediatric patient.

Methods And Results: We present our first case of transcoronary autologous stem cell transplantation in a 9-year-old girl with refractory congestive heart failure secondary to myocardial infarction 1 year after transcatheter revascularization.

Assessment of pulmonary vasoreactivity in children with pulmonary hypertension.

Purpose Of Review: With the current advance in understanding and treatment of pulmonary arterial hypertension in children, pulmonary vasoreactivity testing would navigate the treatment option. An inclusive review of the milestone studies and also recent literature over the last few years on the pulmonary vasoreactivity testing in children will provide the update on various available pulmonary vasodilator agents, markers related to vasoreactivity response, the implication of the testing result on child management and outlook for the long-term outcome.

Recent Findings: There continue to be emerging data regarding pulmonary vasodilators for vasoreactivity testing in children and the genetic predictor of pulmonary vasoreactivity response, particularly in children with idiopathic and familial pulmonary hypertension.

Aerosolized iloprost for pulmonary vasoreactivity testing in children with long-standing pulmonary hypertension related to congenital heart disease.

Background: In congenital heart disease with increased pulmonary blood flow and pressure, progressive changes in the vascular structure can lead to irreversible pulmonary hypertension (PH). Pulmonary hemodynamic parameters are used to determine whether surgical correction is no longer indicated. In this study, aerosolized iloprost was used to assess pulmonary vasoreactivity in children with long-standing PH related to congenital heart disease.

Pacing in preterm with hydrops fetalis due to congenital complete heart block.

Hydrops fetalis due to congenital complete heart block (CCHB) is a rare condition. The outcome of the preterm fetus with hydrops fetalis due to CCHB is poor, and is frequently associated with significant morbidity and mortality. The management of this condition is difficult.

Pericardial effusion in primary systemic carnitine deficiency.

A patient with pericardial effusion and a complicated presentation of primary systemic carnitine deficiency (PSCD) is described. This is the first case of PSCD reported to have pericardial effusion. Compound heterozygosity for two mutations in the SLC22A5 gene, T440M and F23del, and four SLC22A5 polymorphisms (c.

The right and left ventricular function after surgical correction with pericardial monocusp in tetralogy of fallot: mid-term result.

Background: Surgical repair of tetralogy of Fallot (TOF) with reconstruction of the right ventricular (RV) outflow tract invariably results in pulmonary regurgitation (PR). Chronic PR has been associated with RV dysfunction and ventricular arrhythmia. Pericardial monocusp has recently been used at Ramathibodi Hospital to preserve pulmonary valve function.

Oral ibuprofen and indomethacin for treatment of patent ductus arteriosus in premature infants: a randomized trial at Ramathibodi Hospital.

Background: Ibuprofen given intravenously to premature newborn infants is a proven treatment for patent ductus arteriosus (PDA). The efficacy of ibuprofen is comparable to indomethacin in many clinical trials with fewer renal side effects. However, the intravenous form of ibuprofen is not available in Thailand, whereas, the oral suspension form is widely used for antipyretic treatment in children.

Treatment of Kawasaki disease with a moderate dose (1 g/kg) of intravenous immunoglobulin.

Background: Kawasaki disease is an acute febrile illness recognized most often in young children. Coronary abnormality is the most serious complication preventable with intravenous immunoglobulin (IVIG) administration. Various treatment regimens of IVIG have been reported.

Correction of absent pulmonary valve syndrome using a pericardial valved conduit.

Absent pulmonary valve syndrome in a 4-month-old infant was successfully corrected using a fresh autologous pericardial trileaflet valved conduit. He recovered from operation with only mild pulmonary regurgitation at 4 months postoperatively. This technique is an effective alternative for infants with congenital heart disease who need tissue valved conduits.
