An 82-year old woman presented with chest pain and was diagnosed as having acute myocardial infarction. Coronary angiography (CAG) showed 90% stenosis in the proximal left anterior descending artery (LAD). The patient underwent percutaneous coronary intervention using a sirolimus-eluting stent (SES). A repeat CAG performed 6 months after SES implantation revealed no problems. Eight years later,...

ALCAPA a rare congenital coronary anomaly, which usually manifests as an isolated defect, and can develop when there is an embryological failure of normal communication to the left coronary bud in the aorta, with an abnormal connection to the pulmonary bud instead. If left untreated, up to 90% of pediatric patients with this syndrome die within the 1st year of life. To survive beyond infancy, p...

Spontaneous rupture, fistula formation, thrombosis, distal embolisation and myocardial ischaemia are potential complications of coronary and vascular aneurysms. Several surgical techniques have been described to treat these aneurysms: ligation of the aneurysm, resection with end-to-end anastomosis, and vascular or coronary bypass grafting. Indications to treat coronary aneurysms remain unclear,...

UNLABELLED A 10-year-old boy with polysplenia syndrome was diagnosed with complex congenital heart disease, including common atrium, bilateral superior vena cava, complete atrioventricular canal defect, severe pulmonary stenosis, interrupted inferior vena cava, and patent ductus arteriosus. Previously, he underwent a bilateral bidirectional Glenn shunt operation with ligation of the patent duct...

The time course of ventricular arrhythmias in the early period (0--30 minutes) after ligation of the left anterior descending coronary artery was studied in 41 open-chest mongrel dogs anesthetized with pentobarbital sodium (Nembutal). ECGs and seven single and composite electrograms from various regions in and around the ischemic zone were recorded throughout the experiments. Two periods of ven...

BACKGROUND Changes in stress and tissue material properties have been proposed as important mechanical factors that may influence infarct expansion and subsequent healing. Because such changes will be reflected by alterations in the finite deformation of the tissue, we examined the direction and magnitude of myocardial deformation after coronary ligation in the pig. METHODS AND RESULTS Gold b...

Giant coronary artery aneurysms are rare clinical entities. We report the case of a 49-year-old man who presented with dyspnoea and exertional chest pain. Investigations confirmed an aneurysmal right coronary artery measuring 4 cm with a fistulous communication to the right atrium. Following right atriotomy, the fistula was oversewn and the aneurysmal right coronary artery ligated at its origin...
