INTRODUCTION Coronary artery fistulas are abnormal communications between a coronary artery and a cardiac chamber or a major vessel (vena cava, pulmonary vein, pulmonary artery). They are usually diagnosed by coronary arteriography. Clinical presentations are variable depending on the type of fistula, shunt volume, site of the shunt, and presence of other cardiac conditions. CASE PRESENTATION...
We present the clinical, angiographic and surgical findings in a 63-year-old man with anomalous origin of the left main coronary artery from the right sinus of valsalva. The course of the left main artery was abnormal in that it passed between the aorta and the pulmonary artery; in addition, there was obstructive disease involving the left main coronary artery. The association of these two enti...
Anomalous origin of the right coronary artery is a rare congenital anomaly, but is associated with sudden death. Originating from the opposite sinus of Valsalva, an interarterial course and an intramural course are especially considered as the risk factor for fatal cardiac events. Surgical indication remains controversial because many patients are asymptomatic. A 52-year-old man with anomalous ...
Multivessel or multisegment spasm in patients with known widespread coronary atherosclerotic disease is an infrequent occurrence. We describe a prolonged spasm of both the left main and the left anterior descending artery in a patient with chronic effort angina and multivessel coronary artery disease, who previously underwent percutaneous coronary intervention and drug eluting stents implantati...
Introdution: Ischemic mitral regurgitation (IMR) remains one of the most complex and unresolved aspects of ischemic heart disease that the impact of percutaneous coronary intervention (PCI) on improvement of intensity of ischemic mitral regurgitation is not well clarified. Patients with coronary artery diseases and ischemic mitral regurgitation have a worse prognosis than the patients with coro...
One hundred and eight patients with single and multiple vessel coronary artery disease confirmed by arteriography were evaluated by exercise thallium-201 (201Tl) myocardial scintigraphy to determine the scintigraphic appearances of specific coronary stenoses. In general proximal stenoses caused more widespread, but not necessarily more severe, myocardial tracer deficit than distal stenoses. In ...
Left main coronary artery stenosis is an important cause of symptomatic coronary artery disease, although relatively infrequent. The current guidelines recommend coronary artery bypass grafting as the first line treatment and standard of care, but percutaneous coronary intervention is likely to lead to faster reperfusion of coronary flow, avoiding the delays of a major surgical intervention.
