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.

Pulse oximetry screening for clinically unrecognized critical congenital heart disease in the newborns.

Aim: To determine the incidence of clinically unrecognized critical congenital heart disease (CCHD) in the newborns by using pulse oximetric screening.

Methods: Pulse oximetry was performed on clinically normal newborns at 24-48 hours of age. If screening oxygen saturation (SpO(2)) was below 95%, echocardiography was then performed.

Epidemiologic study of Kawasaki disease and cases resistant to IVIG therapy in Thailand.

The incidence of Kawasaki disease (KD) in Thailand has never been studied before. We reviewed the data from the National Registry of Thai Children who had KD between 1998-2002 to evaluate the incidence of KD and cases resistant to treatment with intravenous immunoglobulin (IVIG). Resistance to IVIG was defined as remaining febrile at least 48 hours after initial IVIG therapy.

Chromosome 22q11 deletion syndrome: the first three cases reported in Thailand.

The DiGeorge, velocardiofacial, and conotruncal anomaly face syndromes were originally described as separate disorders due to different concerns regarding phenotypes. However, all these disorders have some common clinical manifestations, including congenital heart defect, facial anomaly, and developmental delay. It is now clear that most cases of these syndromes have a common cause resulting from microdeletion of chromosome 22q11.

Residual patent ductus arteriosus shunting after single Gianturco coil occluding.

Transcatheter occlusion with Gianturco coils has become the treatment of choice for small patent ductus arteriosus (PDA). Coil occlusion was attempted in 20 patients with ductus diameter less than 4 mm who did not require other cardiac surgery. Sixteen of 20 patients had successful implantation.
