We report a patient with a large coronary artery to bronchial artery anastomosis causing angina by coronary steal. Angina was refractory to medical treatment, but successfully relieved by surgical ligation of the anastomosis.

The pressure-induced remodeling of coronary veins is important in coronary venous retroperfusion. Our hypothesis is that the response of the large coronary veins to pressure overload will depend on the degree of myocardial support. Eleven normal Yorkshire swine from either sex, weighing 31-39 kg, were studied. Five pigs underwent ligation of the left anterior descending (LAD) vein, and six serv...

Chronic left ventricular failure developed two months after ligation of an apparently uncomplicated large ductus arteriosus in a one year old girl. Two years later deterioration had progressed to a terminal stage. An anomalous left coronary artery arising from the pulmonary artery had not been recognised before duct ligation. This anomaly was diagnosed two years after ligation and was then trea...

Epinephrine and noiepinephiine, in doses which cause little ectopic activity in unanesthetized normal clogs, produce exaggerated ectopic responses about the fourth day after coronary ligation, when the arrhythmias caused by the ligation per se have subsided. These responses persist for approximately 12 days after ligation and suggest reactivation of latent ectopic foci. Observations with methox...

Mouse myocardial infarction (MI) models are frequently used research tools. The most commonly applied model is coronary artery ligation. However, coronary ligation often gives rise to apical aneurysmatic infarcts of variable size. Other infarct models include cryoinfarction, which produces reproducible infarcts of the anterior wall. Thus far, this model has not been extensively described in mic...

Background. Myocardial ischemial reperfusion represents a clinically relevant problem associated with thrombolysis, angioplasty, and coronary bypass surgery. Injury of myocardium due to ischemial reperfusion includes cardiac contractile dysfunction, arrhythmias, and irreversible myocytes damage. These changes are considered to be the consequence of imbalance between the formation of oxidants an...

Mycotic aneurysms of the coronary arteries are extremely rare, with 15 cases reported. We report the successful treatment of a mycotic aneurysm of the left anterior descending coronary artery by coronary artery bypass grafting with aneurysm ligation and resection without the use of cardiopulmonary bypass.

We aim to explore the influence of Guizhi decoction(GD) on inflammatory response in myocardial ischemia models. 45 New Zealand rabbits were divided into three groups randomly: sham control group, group and + decoction treatment group. The treated with or saline for 20 days. After that, model was created by left anterior descending coronary artery ligation. Color Doppler Echocardiography compute...

: Hemodynamic changes accompanying the initial breaths at time of birth are especially important for a smooth transition fetal to neonatal circulation. Understanding normal transitional physiology and clinical impact adverse adaptation is delineating pathology so as guide physiologically relevant therapies. Disorders such severe perinatal asphyxia, hemodynamically significant patent ductus arte...

Anomalous origin of the right coronary artery from the pulmonary artery is a rare condition. Two cases are presented in this paper. One case was treated by ligation and coronary artery bypass. The other was treated by direct reimplantation of the anomalous coronary artery into the aorta.
