Congenital coronary artery anomalies are rare, with an incidence of about 0.06-1.3 percent of all patients undergoing cardiac catheterisation. They are commonly asymptomatic, but potentially serious lesions may lead to myocardial ischaemia, infarction and/or sudden cardiac death. The occurrence of a concomitant stenotic lesion is exceedingly rare. We report an 80-year-old man who presented with...
When stenting an ostial or proximal coronary lesion, 1 fundamental decision is whether to extend the proximal end of the stent into the aorta (in the case of the left main [LM] or right coronary ostium) or into the polygon of confluence of the LM (in the case of the left anterior descending [LAD] ostium). Complete angiographic and intravascular ultrasound data and 9-month follow-up angiographic...
A 57-year-old male visited our clinic with chief complaint of exertional chest pain. He had been on anti-hypertensive medication for 15 years. In 1999, he went through coronary artery bypass graft surgery for myocardial infarction, using an aorto-left anterior descending artery (LAD) bypass with the left internal mammary artery, and aorto-right coronary artery (RCA) bypass with saphenous vein. ...
a 78-year-old woman was referred for coronary angiography with the chief complaint of exertional angina and dyspnea of a very long duration during routine daily physical activities. she had a history of poorly controlled hypertension and dyslipidemia. coronary angiography revealed diffuse three-vessel disease. interestingly, an unusual branch was noted originating from the mid shaft of the left...
Purpose: Overlapping and foreshortening on conventional coronary angiography is one reason why the presence of ostial lesions in the left anterior descending artery (LAD) is an independent predictor of insegment restenosis. Our previous study using 3-dimensional reconstruction coronary angiography demonstrated the superiority of a deeper caudal projection in clearly showing the ostium of the LA...
BACKGROUND AND PURPOSE The precise clinical characteristics of acute encephalopathy with bilateral reduced diffusion are not fully understood. We compared clinical, laboratory, and neuroimaging findings according to the patterns of brain lesions among children with reduced diffusion in the bilateral hemispheres. MATERIALS AND METHODS Nine patients were analyzed. The patterns of brain lesions ...
OBJECTIVES This study investigated the association between arterial remodeling and geographic distribution of cardiac allograft vasculopathy (CAV), and outcomes after heart transplantation. BACKGROUND CAV is characterized by a combination of coronary intimal thickening and pathological vessel remodeling, which varies at different locations in coronary arteries. METHODS In 100 transplant rec...
PURPOSE Several alternative procedures have been proposed to achieve complete revascularization in the presence of diffuse left anterior descending coronary artery (LAD) disease. With the extensive use of internal thoracic artery grafts in coronary artery bypass procedures, sequential anastomosis of the left internal thoracic artery (LITA) to LAD has gained popularity in these challenging cases...
BACKGROUND Balloon angioplasty yields suboptimal results and increases the rate of restenosis in the ostium of the left anterior descending coronary artery (LAD). Several non-balloon devices have been used to improve the outcome of dilatation of such lesions. METHODS This investigation retrospectively compared the results of a directional atherectomy (DCA)-based intervention and stenting alon...
BACKGROUND Recent studies suggested that perivascular components, such as perivascular adipose tissue (PVAT) and adventitial vasa vasorum (VV), play an important role as a source of various inflammatory mediators in cardiovascular disease. OBJECTIVES The authors tested their hypothesis that coronary artery spasm is associated with perivascular inflammation in patients with vasospastic angina ...
