Survival after cardiac arrest or sustained ventricular tachycardia in patients with hypertrophic cardiomyopathy.
The aim of this study was to evaluate the survival of patients with hypertrophic cardiomyopathy (HCM) after resuscitated ventricular fibrillation or syncopal sustained ventricular tachycardia (VT/VF) when treated with low dose amiodarone or implantable cardioverter defibrillators (ICDs). ⋯ This study shows that patients with HCM who survive an episode of VT/VF remain at risk for a recurrent event. Implantable cardioverter defibrillator therapy appears to offer the best potential benefit regarding outcome.

Troponin-I for prediction of early postoperative course after pediatric cardiac surgery.
It was the aim of the study to test the prognostic value of cardiac troponin-I (cTnI) concerning the early postoperative course after pediatric cardiac surgery. ⋯ Cardiac troponin-I serum levels after open heart surgery in children and infants 4 h after admission to the ICU allowed anticipation of the postoperative course and correlated with the incidence of significant postoperative complications.

Pregnancy among women with congenitally corrected transposition of great arteries.
The outcome of pregnancy in congenitally corrected transposition of the great vessels was studied in 22 women. ⋯ Successful pregnancy can be achieved in most women with congenitally corrected transposition of the great arteries. The rate of fetal loss and maternal cardiovascular morbidity is increased. Because of the small number of births, the risk of congenital heart disease in offspring of women with congenitally corrected transposition of the great arteries is uncertain.

Narrowing of the superior vena cava-right atrium junction during radiofrequency catheter ablation for inappropriate sinus tachycardia: analysis with intracardiac echocardiography.
The study explored the potential for tissue swelling and venous occlusion during radiofrequency (RF) catheter ablation procedures using intracardiac echocardiography (ICE). ⋯ The delivery of multiple RF ablation lesions, often necessary for cure of IST, can cause considerable atrial swelling and resultant narrowing of the SVC-RA junction. Smaller venous structures, such as the coronary sinus and the pulmonary veins, would also be expected to be vulnerable to this complication. Thus, ICE imaging may be helpful in preventing excessive tissue swelling leading to venous occlusion during catheter ablation procedures.
