1/34. Integrated approach for revascularization in multivessel coronary artery disease and porcelain aorta.We report two cases in which combined beating heart revascularization of the left anterior descending artery (LAD) and percutaneous angioplasty of the non-LAD target arteries were adopted after the intraoperative detection of porcelain aorta and impossibility to complete surgical revascularization. This type of strategy preserves the benefits of surgical LAD grafting and complete revascularization and results in a simple and low-risk technical procedure in an otherwise challenging setting.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/34. Fatal cardiac beta2-microglobulin amyloidosis in patients on long-term hemodialysis.We report two long-term hemodialysis patients who developed severe congestive heart failure attributable to cardiac heavy amyloid deposition. Both patients became hypotensive during dialysis sessions, gradually making it difficult to continue hemodialysis, and they died of congestive heart failure. At autopsy, left ventricle walls in each case contained diffuse extensive deposits of amyloid. The distribution of amyloid was not localized to vessel walls but was widely disseminated throughout the left ventricle walls and replaced myocardial muscle fibers. Immunohistochemical examination showed positive staining for anti-human beta2-microglobulin antibody. We conclude that cardiac dialysis-related amyloidosis should also be considered in long-term hemodialysis patients with congestive heart failure as a life-threatening complication.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
3/34. Catheter-based techniques for closure of coronary fistulae.This study details different methodologies of percutaneous closure of arteriosystemic and arteriovenous coronary fistula. Seven patients underwent transcatheter intervention of 10 fistulas, with 7 fistulas successfully closed: 6 with embolic coil devices and 1 with a covered stent obstructing the fistula ostium. The major complication encountered was one death as a result of device recoil into a major epicardial vessel. Percutaneous transcatheter closure of coronary fistulas appears to be simple, facile, and effective. However, device recoil into an undesired arterial segment, while irritating in a noncoronary arterial tree, may be catastrophic when occurring in an epicardial coronary artery.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
4/34. Cardiac and great vessel thrombosis in Behcet's disease.Behcet's disease (BD) is a chronic relapsing systemic vasculitis in which orogenital ulceration is a prominent feature. The disease affects many systems and causes hypercoagulability. We present a 27-year-old male patient who exhibited widespread great vessel thrombosis including right atrial and ventricular thrombi in the setting of right-sided infectious endocarditis and orogenital aphthous ulcerations and erythema nodosum due to BD. We reviewed the enigmatic prothrombotic state of BD, and discuss our prior experiences in this field.- - - - - - - - - - ranking = 1.25keywords = vessel (Clic here for more details about this article) |
5/34. Scleroderma heart disease with slow flow velocity in coronary arteries.A young woman with scleroderma heart disease is presented. Complete work-up including hemodynamic studies revealed biventricular dysfunction, left ventricular hypokinesia and normal coronary arteries with slow flow velocity in coronary arteries. This finding, though not diagnostic, is consistent with small vessels disease secondary to scleroderma. Favorable prognosis in our patient on medical management is encouraging. No conclusions can be drawn on the basis of one patient. Further work is warranted in scleroderma patients with cardiomegaly to define the status of the myocardial microcirculation and its possible role in their prognosis.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
6/34. Large extracranial vertebral aneurysm with absent contralateral vertebral artery.The extracranial segment of the vertebral artery is well protected, and the rate of occurrence of extracranial vertebral aneurysms is very low. We describe the case of a 40-year-old woman who presented with a large aneurysm of the left vertebral artery in the angiographic absence of a right vertebral artery. Her medical history included a motorcycle accident at the age of 20, at which time a neck sprain had been diagnosed. Computed tomography of the chest and neck revealed a 6- x 4-cm aneurysm with mural thrombus in the left thoracic outlet and in the first portion of the left vertebral artery before the entrance of the transverse foramen of the 6th cervical vertebra. angiography of the arch vessels confirmed both the presence of an aneurysm of the left vertebral artery and the absence of a right vertebral artery. Due to the lack of contralateral vertebral flow, we planned to perform a graft interposition under deep hypothermic circulatory arrest, for cerebral protection. Unfortunately, the patient refused the operation and was lost to follow-up. To our knowledge, there has been no previous report of an extracranial vertebral artery aneurysm in the absence of a contralateral vertebral artery. We believe that deep hypothermic circulatory arrest with graft interposition is the best treatment strategy, although we did not, in this case, have opportunity to treat the patient.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
7/34. Imaging of multiple coronary artery fistulas to right ventricle by transthoracic and transesophageal echocardiography.A 20-year-old woman presented with extremely rare multiple coronary artery fistulas with left circumflex and right coronary arteries as the feeding vessels and two distinct sites of drainage into the posterior wall of the right ventricle near the apex in close proximity. The large left fistula was well depicted by transthoracic echocardiography, whereas the transesophageal approach better delineated part of the smaller right fistula.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
8/34. Right coronary artery-right atrium fistula in primary angiosarcoma of the heart.We report a case of angiosarcoma of the heart, manifested as a continuous murmur. Right coronary arteriography disclosed a paracardiac mass with fistulas from the coronary vessel to the right atrium. Histologic study revealed this to be an angiosarcoma with sinusoidal pattern. To our knowledge, this is the first case of this kind of cardiac tumor presenting as a fistula from a coronary artery to the right atrium.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
9/34. Three-vessel left-ventricular microfistulization syndrome: a rare case of angina.A 55-year-old woman with angina was found to have multiple fistulae from all three major coronary arteries to the left ventricle. The aortography mimicked a severe aortic insufficiency. This rare vascular anomaly can cause a coronary steal phenomenon and subsequent myocardial ischemia in patients without angiographic evidence of major atherosclerotic coronary artery disease.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/34. Cardiac hydatid cyst rupture as cause of death.echinococcosis is a frequent parasitic human infection in sheep-farming areas. It is caused by the larval or the cyst stage of a tapeworm, mainly echinococcus granulosis. humans can be infected by ingesting tapeworm eggs, from which cysts will be developed mostly in the liver and the lung. Cardiac involvement of echinococcosis is rare and its clinical evolution is silent till the complication stage. A young adult died suddenly. The autopsy showed a ruptured hydatid cyst hollowed on the right side of the interventricular septum, protruding in the ventricle. The left pulmonary artery contained white-colored fragments of a membrane, similar to the one found in the right ventricle, associated to small vesicles. All these elements were obstructing this vessel, extending to small pulmonary arterial branches. dissection of the other organs did not show other locations. Microscopic examinations ascertained the diagnosis of echinococcosis. Death was imputed to a right ventricular hydatid cyst rupture with pulmonary artery embolism.- - - - - - - - - - ranking = 0.25keywords = vessel (Clic here for more details about this article) |
