Anomalous Coronary Circulation with Origin of the Left Coronary Artery from the Pulmonary Artery
A 45-year-old woman with angina pectoris, beginning at the age of 16 and progressing to produce incapacitation, was found to have an anomalous left coronary artery arising from the pulmonary artery. Because of the severity of symptoms and progression' of disability, the anomalous artery was ligated at its origin from the pulmonary artery. Pressure in the left coronary system increased from 35/1...
متن کاملAlveolar development after ligation of left pulmonary artery in newborn pig: clinical relevance to unilateral pulmonary artery.
The left pulmonary artery and ductus arteriosus were ligated in 14 pigs at birth. Animals were killed at intervals between two and 24 weeks of age. In all animals, serial chest radiographs were taken. In eight animals, nitrogen-13 lung function studies showed normal fractional ventilation in both lungs and continued growth of the small left lung. After death, the fixed inflated volume was deter...
متن کاملAtrial natriuretic peptide response to unilateral pulmonary artery occlusion.
To test the hypothesis that neural mechanisms evoked by unilateral pulmonary artery occlusion (UPAO) affect the release of atrial natriuretic peptides (ANP) from the heart, hemodynamics and levels of plasma ANP and cyclic guanosine monophosphate (c-GMP) were studied in 11 patients with lung cancer. The UPAO induced a significant rise in heart rate by 5.3 percent, increased mean pulmonary artery...
متن کاملNon-Hydrostatic Pulmonary Edema after Coronary Artery Ligation in Dogs
Pulmonary edema which develops during acute myocardial infarction is generally believed to result solely from pulmonary microvascular hypertension. However, patients with myocardial infarction and pulmonary edema occasionally are found to have normal pulmonary wedge pressure. We report data indicating that pulmonary edema develops after coronary artery ligation despite stable microvascular pres...
متن کاملDifferent Presentation of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery in Adults: Case Reports
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. We report three cases of ALCAPA who survived to adulthood. The first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with ALCAPA using cardiac catheterization and coronary computed tomographic angiography (CTA). The second case was a 30-...
