Oblique coronary artery prolongation approach in anomalous left coronary artery from the pulmonary artery in a low-birth-weight neonate.

A 19-day-old newborn girl weighing 1.9-kg was born with anomalous origin of the left coronary artery (LCA) from the pulmonary artery (PA). Because of the small anatomic structures and long distance between the anomalous origin of the LCA high within the left posterior sinus of the main PA, a simple transfer of the anomalous LCA to the aorta was deemed impossible.

Nonatherosclerotic obstructive vascular diseases of the mesenteric and renal arteries.

Nonatherosclerotic vascular diseases of the mesenteric and renal arteries are considered to occur less frequently than those caused by occlusive atherosclerotic disease. However, when present, they pose a significant diagnostic and therapeutic challenge. Such disorders include fibromuscular dysplasia, median arcuate ligament syndrome, the renal nutcracker syndrome, and some forms of acute and chronic mesenteric ischemia (embolic and thrombotic).

Acute anterior ST-elevation myocardial infarction and electrical storm secondary to nondominant right coronary artery occlusion.

A 42-year-old man emergently presented with chest pain and anterior ST elevation. Refractory ventricular arrhythmias and shock developed rapidly. A coronary angiogram revealed the acute occlusion of a nondominant right coronary artery.
