Background: Artificial coronary artery dissection is observed occasionally during percutaneous coronary intervention. However, “spontaneous” coronary artery dissection (SCAD) is not common and we tried to clarify its characteristics. Methods and Results: We reviewed the serial diagnostic coronary angiograms of 21,500 patients retrospectively. Sixty-two patients showed linear, longitudinal defec...

Spontaneous left main coronary artery (LMCA) dissection is an unusual cause of myocardial ischemia and sudden death. It is defined as an intramural hematoma of the media of the vessel wall. A 56-year-old male who underwent a two-vessel bypass ten years previous presented with chest pain for two hours. His blood pressure and heart rate were 60/35 mmHg and 120 beats per minute, respectively. The ...

Coronary artery ectasia (CAE) is usually defined as the enlargement of all layers of coronary artery segment, with the diameter of the ectatic segment being more than 1.5 times larger than that of the normal segment. Atherosclerotic lesions within the ectatic regions of the coronary arteries appear to be highly inflamed high-risk plaques with proclivity to rupture. However, there is only limite...

Woven coronary artery (WCA) is an extremely rare and still not a clearly de ined coronary anomaly. It is characterized by the division of epicardial coronary artery into thin channels which then reanastomose with the distal part of the abnormal coronary artery [1]. Since the angiographic imaging of WCA looks like an intracoronary thrombus and dissection; the differential diagnosis between ather...

We reported simple partial root remodeling using a graft trimmed twin "U" shape for extensive dissection into the right/non-coronary sinuses with acute type A aortic dissection with cardiac tamponade, acute myocardial infarction on the right coronary artery and aortic regurgitation. After total arch replacement with frozen elephant trunk technique for distal dissection, partial root remodeling ...

Coronary artery dissection is an infrequent cause of acute coronary syndrome in the general population. There is, however, a greater incidence of spontaneous coronary artery dissection (SCAD) in young women, especially in the peripartum period. However, the majority of cases have favorable outcomes with medical management or percutaneous coronary intervention; coronary artery bypass grafting (C...

isolated dissection of the superior mesenteric artery is a rare occurrence with a hitherto unknown exact etiology. patients may present with abdominal symptoms or hemodynamic instability. w e herein present a case of spontaneous isolated superior mesenteric artery dissection in a 48-year-old man, who was admitted with epigastric pain. due to an undiagnosed paced rhythm on the electrocardiogram,...

We describe the clinical course of three patients who developed spontaneous coronary artery dissection. All patients were young women, one 9 weeks pregnant. All presented with chest pain; one died suddenly proving refractory to resuscitation, another developed unstable angina culminating in myocardial infarction, cardiogenic shock and death, and the third patient underwent coronary artery bypas...

The natural history of minimally symptomatic or asymptomatic iatrogenic coronary dissection is not well-defined. While generally considered a serious and life-threatening complication of coronary arteriography, there have been some reported cases of spontaneous resolution without residuals. We describe a case demonstrating that coronary artery dissection, even when initially asymptomatic, may l...
