Late aortic dissection can occur after aortic valve replacement surgery, but rarely in the first postoperative month. Coronary artery dissection is rare and usually occurs after coronary angiography. We report a rare case of coronary artery dissection followed by myocardial infarction in the immediate postoperative period of a successful aortic valve replacement with a good postoperative evolut...
Previous data suggest women are at increased risk of death from aortic dissection. Therefore, we analyzed data from the GenTAC registry, the NIH-sponsored program that collects information about individuals with genetically triggered thoracic aortic aneurysms and cardiovascular conditions. We performed cross-sectional analyses in adults with Marfan syndrome (MFS), familial thoracic aortic aneur...
Ascending aortic dissection is often a catastrophic condition. Dissection into the commissures or into an aortic valve leaflet may lead to leaflet avulsion and valvular insufficiency due to a flail valve. We present an image report describing an important and life-threatening complication due to the movement of a partially dehisced intimal aortic flap into the left ventricle causing aortic valv...
BACKGROUND Carriers of the 719Arg variant in KIF6, compared with noncarriers, have been reported to be at greater risk for coronary heart disease (CHD) in six prospective studies. Because CHD, thoracic aortic dissection, and nondissection thoracic aortic aneurysm share some risk factors and aspects of pathophysiology, we investigated whether carriers of the 719Arg variant also have greater odds...
Case Sometimes it is difficult to diagnose circumferential aortic dissection with enhanced computed tomography alone. A 58-year-old woman presented with sudden-onset chest discomfort and loss of consciousness. Transthoracic echocardiogram showed mild aortic regurgitation. Enhanced computed tomography scans showed no obvious intimal tear or flap at the proximal ascending aorta, but an intimal fl...
Acute aortic dissection bears all the stigmata of a true clinical emergency. The natural history of this acute aortic syndrome warrants prompt surgical intervention, with only a few absolute contraindications to this line of treatment. We present a 74-year-old man with documented metastatic prostate cancer who underwent emergent surgery for acute Stanford A aortic dissection. Having acknowledge...
Acute type-B aortic dissection is generally managed by administering medical treatment with an aim to achieve pain relief and hypertension control. Surgery is usually performed only in cases of type-B dissection complicated with limb ischemia, branch vessel compression or potential fatal aortic rupture. Herein, we report an extremely unusual case of type-B aortic dissection with partial involve...
BACKGROUND Acute aortic syndrome is the modern term that includes aortic dissection, intramural hematoma, and symptomatic aortic ulcer. Iatrogenic coronary artery dissection extending to the aorta during percutaneous coronary intervention is a very rare but life-threatening complication. Despite some reports of spontaneous recovery, most of these patients are treated surgically as a spontaneous...
OBJECTIVE To determine the most effective treatment, we performed a detailed comparative study of the clinical course of patients with type B aortic dissection with a patent or thrombosed false lumen who did not undergo surgery in the acute period. We examined the effect of patency of the false lumen on outcome. METHODS Computed tomography scans of 138 patients with type B acute aortic dissec...
Oxidative stress leads to vascular damage and participates in the pathomechanisms of aortic dissection and aneurysm formation. Here we study aortic dissection in mice deficient in the superoxide-generating reduced nicotinamide-adenine dinucleotide phosphate oxidase NOX1. Seven days of treatment with the hypertensive agent angiotensin II (3 mg/kg per day) led to aortic dissection in 23% of wild-...
