OBJECTIVES This study reports our clinical experience with transcatheter closure of secundum atrial septal defects (ASDs) in children, using the Amplatzer, a new occlusion device. BACKGROUND None of the devices previously used for transcatheter closure of interatrial communications has gained wide acceptance. METHODS We examined the efficacy and safety of the Amplatzer, a new self-centering...
Aim. To identify dysmorphic features and cardiac, skeletal, and urogenital anomalies in patients with congenital hypothyroidism. Patients and Methods. Seventeen children with congenital primary hypothyroidism were recruited. Cause for congenital hypothyroidism was established using ultrasound of thyroid and (99m)Tc radionuclide thyroid scintigraphy. Malformations were identified by clinical exa...
Severe pulmonary arterial hypertension (PAH) rarely develops in children with an atrial septal defect (ASD), even those with a large defect. We herein report the case of a 27-year-old man with a moderate-sized secundum ASD and right ventricular failure due to severe PAH, which developed in his early teens. He was diagnosed as having a genetic mutation of the bone morphogenetic protein receptor-...
We report a case of a 46-year-old woman who presented with subacute exertional dyspnea and severe hypoxia. A large cystic mass compressing the right side of the heart along with right-to-left atrial shunt flow through an alleged atrial septal defect (ASD) were detected on echocardiography. CT scan of the chest and MRI of the heart revealed a loculated cystic mediastinal mass with hemorrhage mea...
OBJECTIVES Atrioventricular block (AVB) is a infrequent and serious complication after percutaneous ASD closure. In this study, we report on the incidence of AVB associated with intraoperative device closure of the ASD with transthoracic minimal invasion, and the outcomes of this complication in our center. METHODS Between May 2006 and January 2011, a total of 213 secundum-type ASD patients w...
UNLABELLED It is common to suspect Eisenmenger syndrome when patients with atrial septal defect (ASD) show cyanosis and clubbing. However, ASD accompanying Ebstein's anomaly frequently shows cyanosis without severe pulmonary hypertension, especially in the early period after birth. So the medical decision to decline surgical treatment in those patients should not be determined merely by clinica...
His bundle electrograms were recorded in 348 patients aged 2 months to 24 years following routine diagnostic cardiac catheterization. Among 41 children found to be free of anatomic or hemodynamic abnormality the following mean values were obtained: P-H interval, 93.4 +/- 15.3 msec; P-A time, 21.2 +/- 7.1 msec; A-H interval, 72.2 +/- 15.9 msec; and H-V interval, 39.8 +/- 5.2 msec. The remaining ...
A 23-year-old male referred for evaluation of a "choking" sensation with exertion and a murmur. A transthoracic echocardiogram demonstrated right atrial and ventricular dilatation, right ventricular volume overload, and a large secundum atrial septal defect (ASD) with left to right shunt and a calculated pulmonary-to-systemic blood flow ratio (Qp/Qs) estimated at 2.3 to 1. Cardiac catheterizati...
