background: atherosclerotic renal artery stenosis (aras) remains underdiagnosed due to its nonspecific demonstrations. we aimed to both estimate the frequency of aras in high-risk non-selected patients undergoing simultaneous coronary and renal catheterization and possibly identify a predictive model for aras using baseline clinical, laboratory, and coronary angiographic variables. methods: the...

aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...

A number of symptomatic patients with coronary artery disease undergo revascularization without definite evidence that particular coronary stenosis is responsible for their symptoms [1]. Currently, the borderline coronary artery stenoses are most commonly assessed by intravascular ultrasound and fractional flow reserve (FFR) alongside with quantitative coronary angiography [2]. FFR measurement,...

Pulmonary vein stenosis is a recently described complication of radiofrequency ablation. We report a patient who experienced thrombosis of the lingular vein and pulmonary infarction resulting from mild single-vessel pulmonary vein stenosis. This report extends available experience with complications of radiofrequency ablation, by demonstrating pulmonary venous thrombosis as a complication of re...

Figure 1: The echo-colour doppler and CT show the complications of an extreme endovascular treatment. (A) Occlusion of the right jugular vein, patency of the trunk of the brachiocephalic and subclavian vein and thrombosis of the left jugular vein and the brachiocephalic trunk with residual stenosis of 70%. (B) The extreme treatment and endovascular stenting (CT view). (C) Occlusion of the right...

The management of intermediate coronary lesions, defined by a diameter stenosis of 40% to 70%, continues to be a therapeutic dilemma for cardiologists. The 2-dimensional representation of the arterial lesion provided by angiography is limited in distinguishing intermediate lesions that require stenting from those that simply need appropriate medical therapy. In the era of drug-eluting stents, s...

the left ventricular aneurysm is one of the most significant complications of myocardial infarction and is defined as the expansion of the ventricular wall. the coronary artery aneurysm is characterized by an abnormal dilation of the localized portion of the coronary artery, and its main cause is atherosclerosis. we herein report an unusual case of coronary artery and left ventricular aneurysms...

BACKGROUND Although saphenous vein grafts (SVG) have been used from 1975 to treat coronary stenosis caused by Kawasaki disease, long-term results after more than 20 years remain unknown. METHODS AND RESULTS From 1981 to 1997, 13 patients underwent coronary artery bypass grafting using SVG (n=20). The age at operation ranged from 2 to 20 years (median 11 years), the age at latest angiography f...

Background. Excimer laser coronary angioplasty has been reported to be a promising treatment for complex coronary artery disease. The purpose of this study was to define the predictors of acute success and restenosis after this experimental intervention. Methods and Resuls. A cohort of 200 consecutive patients had a minimum of 6 months of follow-up evaluation after treatment of 215 coronary ste...
