RESUMO
Patients with hemophilia generally have a reduced frequency of coronary artery disease compared to the general population. As advances in the management of hemophilia have increased their life expectancy, the prevalence of coronary artery disease also has increased. However, there are no standard treatment guidelines for coronary artery disease in patients with hemophilia, especially in the field of coronary intervention. We report the case of a patient with severe hemophilia A who presented with acute coronary syndrome and was successfully treated with percutaneous coronary intervention.
RESUMO
A right atrial and inferior vena caval thrombus in a structurally normal heart is a very rare condition. We report a case of such a thrombus in a 66-year-old woman. She was admitted to our hospital with recent onset dyspnea. Based on echocardiography, we suspected that she had myxoma. We performed an excision of a mass, which was found, by pathologic examination, to be an organized mural thrombus.
RESUMO
Cardiac papillary fibroelastoma (CPF) is a benign cardiac tumor that usually affects cardiac valves. It is usually discovered incidentally on routine echocardiography. However, left ventricular CPF is rare. This report describes the case of a 73-year-old female, referred to a cardiology department for evaluation of a mass of the left ventricle. The mass was found routine echocardiography. The transthoracic echocardiography revealed a 2.2x1.3 cm highly oscillating mass, attached by stalk on the inferior wall of the left ventricle. Cardiac magnetic resonance imaging demonstrated a non-enhanced, 1.8x1.0 cm mass on the inferior wall of the left ventricle. The patient underwent surgical resection of the mass, histopathologic examination of the mass confirmed the diagnosis of a CPF.
RESUMO
BACKGROUND: Despite several case reports of sirolimus-eluting stent (SES) fracture and concern regarding restenosis after successful SES implantation, the clinical characteristics of this problem are not well known. METHODS: Clinical records and angiographic films of patients who received follow-up coronary angiography between February 2005 and October 2006 were retrospectively analyzed. RESULTS: Among the 686 SES implanted in 479 patients, 27 fractures were found in 22 (3.2%) stents in 18 patients. All stent fractures occurred in long stented segments, i.e. >/=28 mm (range, 28 mm to 83 mm). Of the 22 fractured stents, sixteen (72.7%) were identified in the right coronary artery (RCA) and fifteen (68.2%) were found to have a fracture site within 10 mm from areas with increased rigidity due to metal overlap. The significant multivariate predictors of stent fracture were the stented length (Odds ratio 1.06; 95% confidence interval 1.04-1.09; p=0.001) and the RCA location (Odds ratio 4.44; 95% confidence interval 1.66-11.86; p=0.003). The binary restenosis rate was 22.7% and target lesion revascularization was performed in two (9.1%) fractured stents. CONCLUSIONS: SES fracture was associated with a long stented segment, RCA location and metal overlap. Stent fracture may be another potential risk factor for restenosis after successful SES implantation.
