Double Outlet Right Ventricle with intact ventricular septum is an extremely rare malformation. Only nine cases are recorded in the known world literature. A new case is reported, concerning a female infant six months old when first seen, and still alive after atrial septectomy. The anatomical studies in Double Outlet Right Ventricle suggest that only the Ventricular Septal Defect in the outlet...

Ventricular tachycardia (VT) may cause sudden death late after repair of congenital heart disease. Radiofrequency catheter ablation (CA) of VT can be effective but may be hampered by hypertrophied myocardium or prosthetic material. A 33-year-old man with congenitally corrected transposition of the great arteries (ccTGA) had undergone a double switch operation (DSO) with the combined Mustard and...

or complicated ventricular septal defects. The main indication for the procedure was intractable congestive cardiac failure not responding to medical therapy. There was a I2 per cent mortality. Complications resulting from the operation are recorded. Twenty of these children have subsequently undergone repair of the ventricular septal defect and reconstruction of the pulmonary artery with a mor...

The major limitation of current engineered myocardial patches for the repair of heart defects is that insulating polymeric scaffold walls hinder the transfer of electrical signals between cardiomyocytes. This loss in signal transduction results in arrhythmias when the scaffolds are implanted. We report that small, subtoxic concentrations of single-walled carbon nanotubes, on the order of tens o...

Combined two-dimensional and Doppler echocardiography has a high sensitivity and specificity for detection of isolated perimembranous ventricular septal defects. However, muscular or multiple ventricular septal defects may be difficult to diagnose with noninvasive methods, particularly in older children, necessitating angiography for accurate diagnosis. Detection of single and multiple ventricu...
