1/188. Tc-99m HDP uptake in cardiac amyloidosis.amyloidosis is characterized by the soft-tissue deposition of amyloid protein. It may occur as a primary disorder but more often is seen as a manifestation of chronic illness. Scattered reports of the affinity of amyloid for bone scanning agents have appeared over many years. Isolated cardiac uptake of Tc-99m HDP is described in a patient with biopsy-proved cardiac amyloidosis on a background of tuberculosis, prostate cancer, and coronary artery disease.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/188. Cardiac transplantation in a patient with protein s deficiency.Cardiac transplantation was successfully performed in a patient with end-stage ischemic cardiomyopathy and hereditary protein s deficiency who had undergone two previous coronary artery bypass graft procedures. Routine intraoperative heparinization and reversal with protamine was undertaken, and the antifibrinolytic agent aprotinin was infused throughout the procedure without perioperative hemorrhage or thrombosis. Systemic anticoagulation with intravenous heparin was resumed on postoperative day 2, and the patient was then converted to Lovenex as outpatient anticoagulation to facilitate routine surveillance endomyocardial biopsies.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
3/188. Transient myocardial dysfunction associated with angiotensin-converting enzyme inhibitor-induced angioedema: recognition by serial echocardiographic studies.We report a case of a 58-year-old woman who had angiotensin converting enzyme inhibitor-induced angioedema after she underwent a biopsy of a hypopharyngeal mass. The angioedema was associated with severe transient myocardial dysfunction documented on echocardiography. She did not have anaphylaxis or coronary artery disease. To our knowledge this is the first reported case of transient myocardial dysfunction in the setting of angiotensin converting enzyme inhibitor-induced angioedema without anaphylaxis.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
4/188. 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 = 4keywords = coronary (Clic here for more details about this article) |
5/188. Anomalous origin of the left coronary artery from the pulmonary artery.Anomalous origin of the left coronary artery from the pulmonary artery (ALCA-PA) is a rare form of congenital heart disease. In this report, three cases with this anomaly are described; two patients presented in infancy with heart failure from myocardial ischemia and infarction, while the third was asymptomatic and ALCA-PA was diagnosed during evaluation of a residual murmur after surgery for associated cardiac defects (ventricular septal defect and patent arterial duct). All three cases underwent aorto-pulmonary tunnel repair (Tukeuchi procedure), and to our knowledge two of them are the first infantile cases reported in turkey.- - - - - - - - - - ranking = 5keywords = coronary (Clic here for more details about this article) |
6/188. Acute myocardial injury: an entity of acute coronary syndromes.A 46-year-old Indian man was admitted with unstable angina (Braunwald's class IIIB1)--the chest pain at rest was associated with inferolateral ischaemia on the ECG at admission. His serial total creatine kinase levels were elevated but CKMB was not detected. Serial serum troponin t levels were significantly raised suggesting the presence of significant acute myocardial injury.- - - - - - - - - - ranking = 4keywords = coronary (Clic here for more details about this article) |
7/188. Detection of cardiac calcinosis in hemodialysis patients by whole-body scintigraphy with 99m-technetium methylene diphosphonate.A noninvasive method for the diagnosis of cardiac calcinosis, a life-threatening complication in hemodialysis patients with end-stage renal disease (ESRD), has not, as yet, been firmly established. We tested whether whole body scanning with 99m-technetium methylene diphosphonate (MDP) might visualize cardiac calcinosis. In 19 consecutive chronic hemodialysis ESRD patients (13 males and 6 females, aged 40-81, mean 63 /- 8 years) with cardiovascular disease [mitral annular calcinosis and/or calcified aortic valve (n = 4), hemodialysis cardiomyopathy (n = 1), coronary artery disease (n = 9) and peripheral artery atherosclerotic disease (n = 6)], MDP uptake in the heart was compared to that in 7 non-ESRD controls with hyperparathyroidism due to adenoma. Cardiac and lung field MDP uptake was confirmed in only 3 (16%) and 5 (26%) of the 19 ESRD subjects, respectively, but was absent in controls. Positive cardiac uptake was related to cardiac calcified complications (mobile intracardiac calcinosis, myocardial calcinosis and mitral annular calcification) and the duration of hemodialysis (p = 0.015). While it was statistically insignificant, subjects showing MDP uptake were elder and had higher serum Ca or Ca x P product and lower intact parathyroid hormone levels. These results suggest that cardiac calcinosis in ESRD patients can be detected noninvasively by myocardial scintigraphy with 99m-technetium MDP.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
8/188. hemoptysis following left ventricular aneurysm repair: a misleading clinical sign.We report on a 66-year-old man with severe hemoptysis following coronary artery bypass grafting and repair of a left ventricular septal defect after acute myocardial infarction. Initial diagnosis was delayed by misleading clinical symptoms and radiologic studies. Due to subfebrile temperature and sputum culture positive for pseudomonas aeruginosa, he had been treated with antibiotics before reoperation. At reoperation, replacement of all foreign material and reconstruction of the ventricular repair with bovine pericardium resulted in reinfection with the same organism despite prolonged antibiotic therapy after 6 months. Removal of the pericardial tissue with direct suture closure of the ventricles and interposition of omentum led to complete healing of the infection without reoccurrence after 2 years.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
9/188. Rytand-Lipsitch syndrome.An 84-year-old woman had Rytand-Lipsitch syndrome, ie, total atrioventricular block resulting from destruction of the central areas of the conducting system due to extension of calcification from the fibrous ring of the mitral valve. In a postmortem coronary arteriographic study of 500 hearts, degenerative calcification of the fibrous ring of the mitral valve was demonstrated in 4.4% (95% confidence limits--2.8% to 6.6%), rheumatic valvular changes not being included. There were significantly more women than men with calcification of the mitral valve apparatus (P less than .00005). Division of the material into two groups larger than or equal to 70 years and less than 70 years showed a statistically significant sex difference in the former group (P les than .005), whereas the sex difference was of borderline significance in the latter group (.1 greater than P greater than .05).- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
10/188. Use of fractional flow reserve in the treatment of a calcific bifurcation left anterior descending coronary stenosis with rotational atherectomy.We report the results of an intervention in a high-risk surgical patient undergoing rotational atherectomy in a bifurcating lesion. The use of fractional flow reserve (FFR) was especially helpful due to the inability to visualize clearly the angiographic anatomy both before and following intervention.- - - - - - - - - - ranking = 4keywords = coronary (Clic here for more details about this article) |
