c d r T d r A f ( l o c t A w b t To the Editor: Transcatheter closure of perimembranous ventricular septal defects (pmVSD) is a well-established procedure but is associated with an unacceptable incidence of complete heart block (CHB) (1,2). We describe retrograde single catheter closure of pmVSDs by an off-label use of the Amplatzer duct occluder II (ADO(More)
A 2-year-old boy with cyanosis was found to have normal situs and looping with anomalous drainage of a right-sided superior vena cava to the left atrium, and intact interatrial septum in association with anomalous drainage of the left pulmonary veins to the right superior vena cava. He underwent successful surgical repair of this rare congenital(More)
OBJECTIVES To describe the technique and results of transcatheter closure of ventricular septal defects (VSDs) by a modified retrograde transarterial approach using the new Amplatzer Duct Occluder II (ADO II). BACKGROUND Transcatheter device closure of ventricular septal defects (VSDs) by antegrade method is well established, but a challenging procedure.(More)
BACKGROUND Surgical or transcatheter closure of muscular ventricular septal defects (mVSDs) in young children may be technically challenging and associated with significant complications. OBJECTIVE To assess the feasibility of trans-septal antegrade closure of mVSD in a selected subset of young children. METHODS This is a prospective study from a single(More)
We report a case of incessant ventricular tachycardia managed successfully with medications. The transthoracic echocardiogram showed multiple cardiac rhabdomyomas involving ventricular free wall and outflow tracts. Computerized tomography of brain showed multiple subependymal tubers confirming Tuberous Sclerosis. The follow up assessment showed sinus rhythm(More)
Ventricular septal defect (VSD) is a common congenital heart defect in children. Perimembranous VSD (Pm VSD), a defect involving the membranous septum and the adjacent portion of the muscular septum, accounts for about 70 % of cases. Transcatheter closure of Pm VSDs using the Amplatzer Pm VSD device, although successful in many patients, has been associated(More)
Isolation of the subclavian artery is associated with "steal" of blood from the carotid circulation to the arm, through the circle of Willis and the vertebral artery. When associated with a patent arterial duct, there is an additional "steal" of blood from the arm to the lungs, through the arterial duct because of the lower pulmonary vascular resistance.(More)
A newborn baby presented with respiratory distress, cyanosis and shock within 2 hours of birth. The cardiac evaluation showed supracardiac total anomalous pulmonary venous return with critically obstructed vertical vein. The baby underwent successful stenting of the vertical vein at 12 hours of life.
Four neonates presented within 24 hours of birth with stridor, respiratory distress and a weak cry. Clinical examination of the cardiovascular system revealed no abnormality. The transthoracic echocardiogram showed large aneurysm of ductus arteriosus at the aortic isthmus, tapering to a small tortuous channel at the site of pulmonary artery insertion.(More)
