1/192. 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 = coronary (Clic here for more details about this article) |
2/192. Localized pericarditis with calcifications mimicking a pericardial tumor.A 62-year-old man was admitted with increasing palpitations. radiography of the chest demonstrated a calcified mass. magnetic resonance imaging revealed compression of the right ventricle by a tumor. At the time of cardiac catheterization, the coronary arteries were found not to supply blood flow of the mass, and no dip-and-plateau pattern was seen in the right ventricular pressure measurements. At the time of surgery, the mass was found to be a focal calcified thickening of the pericardium containing only pus. The thickening resembled an oval pericardial tumor. Microbiologic examination of the pus revealed propionibacterium acnes.- - - - - - - - - - ranking = 0.25keywords = coronary (Clic here for more details about this article) |
3/192. Calcified splenic artery aneurysm discovered during coronary arteriography.We present a case of calcified splenic artery aneurysm discovered during routine coronary angiography. Early awareness of these aneurysms is important since their rupture may cause serious complications. This case emphasizes the importance of attention to cardiac and extra-cardiac structures during coronary angiography.- - - - - - - - - - ranking = 1.5keywords = coronary (Clic here for more details about this article) |
4/192. Coronary artery erosion and dissection: an unusual complication of mitral annular calcification.This article describes a 42-year-old male patient with a longstanding history of insulin-dependent diabetes mellitus, systemic arterial hypertension, and chronic renal failure. The patient had severe mitral annular calcification (MAC) identified at autopsy. This MAC was of an amorphous, caseous-appearing type; it displaced the posterior mitral valve leaflet and extruded into the myocardium of the lateral and posterolateral left ventricle to involve the epicardial surface. The MAC produced extramural erosion of the wall, and dissection into the media, of the first left/obtuse marginal coronary artery. This coronary artery involvement by, and other complications of, MAC are discussed.- - - - - - - - - - ranking = 0.5keywords = coronary (Clic here for more details about this article) |
5/192. Difference in structural change in the Carpentier-Edwards pericardial valves implanted in the mitral and tricuspid positions.We report a 29-year-old patient with prosthetic valve dysfunction with severe calcific stenosis in the mitral position but no structural change in the tricuspid position after mitral valve replacement and tricuspid valve supra-annular implantation with same bioprostheses at the seven years before. The difference in structural change between the mitral position and the tricuspid position might be due mainly to the effect of mechanical stress on the cusps, rather than to any difference in serum calcium levels. However, some hormonal effect other than that of the parathyroid hormone on the systemic and pulmonary circulation might be related to the early progression in cusp calcification in the systemic circulation.- - - - - - - - - - ranking = 0.006600904591492keywords = circulation (Clic here for more details about this article) |
6/192. Repeated balloon rupture during coronary stenting due to a calcified lesion: an intravascular ultrasound study.We describe a patient in whom balloon rupture occurred three times during inflation in a stent with restenosis in the left anterior descending artery. The cause of rupture was detected by intravascular ultrasound: a calcified ridge that protruded between the stent struts in the distal stent body.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
7/192. Ultrasonic aortic valve decalcification.We report a case of calcific aortic stenosis in a 79-year-old man who had undergone aortocoronary bypass. Since ordinary valve replacement was problematic because of severe annular calcification, a small annular diameter, and three patent vein grafts, we performed ultrasonic aortic valve decalcification. As a result, the pressure gradient across the aortic valve decreased from 100 mmHg to 25 mmHg, and the patient is doing well to date at two years after the operation. Although long-term results of ultrasonic aortic valve decalcification are still undetermined, it appears worth considering in cases in which ordinary valve replacement could be extremely difficult.- - - - - - - - - - ranking = 0.25keywords = coronary (Clic here for more details about this article) |
8/192. Using coronary calcification scanning in the clinical practice of preventive cardiology.Preventive therapies such as cholesterol reduction significantly reduce the risk of acute coronary events. Diagnostic tools that identify asymptomatic coronary atherosclerosis would permit initiation of aggressive preventive therapies at an earlier stage of coronary disease. Histologic and angiographic data demonstrate that coronary calcium has a very high sensitivity for the presence of coronary plaque. Therefore, coronary calcification can be regarded as a marker for coronary atherosclerosis. Coronary calcium scanning has been suggested as a tool for identification of a high-risk asymptomatic patient group. It can be utilized to guide the aggressiveness of risk factor modification and therapeutic preventive interventions toward those at higher risk for future events. Based on the available data, we review the clinical use of coronary calcium scanning in preventive cardiology.- - - - - - - - - - ranking = 3keywords = coronary (Clic here for more details about this article) |
9/192. Dystrophic calcification of the radial artery.The radial artery continues to enjoy resurgence in popularity as a conduit for coronary artery bypass grafting but few studies have examined the prevalence of preexisting disease in this vessel. We highlight a potential, avoidable pitfall when use of the radial artery for coronary artery bypass grafting is proposed.- - - - - - - - - - ranking = 0.5keywords = coronary (Clic here for more details about this article) |
10/192. aortic valve replacement for the calcified ascending aorta in homozygous familial hypercholesterolemia.A 72-year-old woman who had been diagnosed as homozygous familial hypercholesterolemia was admitted for chest discomfort. Computed tomography and cardiac catheterization revealed severe calcification of the aortic root and a high grade stenosis of the proximal right coronary artery. aortic valve replacement concomitant with coronary artery bypass was done using temporary hypothermic circulatory arrest. This is preferred method when dealing the calcified aorta.- - - - - - - - - - ranking = 0.5keywords = coronary (Clic here for more details about this article) |
