A transvenous lead system for implantable defibrillators would obviate a surgical thoracotomy and reduce the morbidity and mortality associated with implantation. We evaluated the clinical performance of a new nonthoracotomy lead system that included a defibrillation lead in the coronary sinus. At the time of defibrillator implantation, transvenous defibrillation leads were inserted percutaneou...

detection of causes of sudden natural death is a major problem of physicians and exact inspection of rare causes of sudden death reduces numbers of white autopsies and helps to well performance of justice. anomalous origin of coronary arteries are one of these rare cases that mostly in infants leading to death due to ischemia and heart failure , and sometimes survive until adulthood and attenti...

Coronary sinus occlusion retards necrosis of ischemic myocardium. To test the hypothesis that coronary sinus occlusion induces retrograde venoarterial flow, the coronary arteriovenous pressure gradient and the coronary arterial oxygen saturation were measured distal to a left anterior descending coronary artery ligature in dogs. In parallel, we constructed a mathematical model of known coronary...

Single coronary artery is a rare anomaly, with a reported incidence of 0.024%. It can be diagnosed on coronary computed tomography angiography, where the presence of ostial narrowing and compression between the great vessels must be carefully excluded, since these malignant forms can lead to sudden cardiac death and other ischemic complications. We describe a case of single coronary artery aris...

This is a case of a patient requiring pacemaker support after right ventricular assist device (RVAD) implantation. Due to complete heart blockafter right ventricular infarction, a pacemakerwith anatrial leadandaventricular lead into thecoronarysinuswas implanted.Although RVAD patients requiring pacemakers lack the typical RV implantation site for the ventricular lead, the coronary sinus can be ...
