Various methods of cerebral protection have been used during such aortic arch operations as the Norwood Procedure and operations on the interrupted aortic arch in neonates and infants. Deep hypothermia with circulatory arrest is the most common technique, but has a limited safe period for circulatory arrest. Antegrade cerebral perfusion has been introduced to prolong this safe period. We review...

To the Editor: We would like to compliment Zipes and Wellens on their excellent article about sudden cardiac death, which was recently published in Circulation.1 We think, however, that calcium channel blockers deserve a mention in this review as a potential treatment for patients who are resuscitated from cardiac arrest. Isolated coronary spasm without associated coronary obstruction can occas...

Complete heart block frequently requires emergency pacing to restore systemic perfusion. We report the case of a 3-yr-old girl undergoing interventional atrial septal defect closure who suffered from transient complete heart block with circulatory arrest. Transthoracic mechanical pacing for more than 3 min provided temporary support, sustaining an adequate cardiac output until sinus rhythm resu...

We report on an unusual case of surgical repair for anomalous origin of the coronary artery from the pulmonary artery, in a young patient who underwent tunnel repair with concomitant heterotopic heart transplantation to support severely impaired left ventricular function. Four years later, the graft was removed after confirmation of ventricular arrest and excellent recovery of the patient's own...

INTRODUCTION Vasodilators like nitroglycerin or nitroprusside improve hemodynamics in patients with advanced heart failure. However, using these agents in critical conditions is limited because of their ability to decrease systemic blood pressure. CASE PRESENTATION We report the rapid effect of high dose intravenous nitroglycerin treatment in an 86-year-old man after cardiac arrest and prolon...

Left ventricular non-compaction (spongy myocardium) is one of the most misclassified cardiomyopathies. It is characterised by an excessively prominent trabecular meshwork of myocardium and deep intertrabecular myocardium due to an arrest in the compaction process of the myocardial fibres. It could be isolated i.e. without any other structural heart defects or associated with congenital heart de...

Sinus node dysfunction occurs occasionally after heart transplantation and may be caused by surgical trauma, ischemia to the sinus node, rejection, drug therapy, and increasing donor age. However, the timing and indication of permanent pacemaker insertion due to sinus node dysfunction following heart transplantation is contentious. Here, we report a case of a permanent pacemaker insertion for s...

Objective(s): The aim of this study was to investigate the effects of mild hypothermia on expression of NF-E2-related factor 2 (Nrf2) and heme-oxygenase-1 (HO-1) of rat cerebral cortex and hippocampus after cardiopulmonary resuscitation and further investigate the possible mechanism of action. Material and Methods:To copy an asphyxia heart arrest model, Sprague Dawley rats were randomly divided...
