BACKGROUND Cardiac tumors are extremely rare; however, when there is clinical suspicion, proper diagnostic evaluation is necessary to plan the most appropriate treatment. In this context, cardiovascular magnetic resonance imaging (CMRI) plays an important role, allowing a comprehensive characterization of such lesions. OBJECTIVE To review cases referred(More)
Inferior vena cava anomalies are rare, occurring in up to 8.7% of the population, as left renal vein anomalies are considered. The inferior vena cava develops from the sixth to the eighth gestational weeks, originating from three paired embryonic veins, namely the subcardinal, supracardinal and postcardinal veins. This complex ontogenesis of the inferior(More)
Background Chagas’ Cardiomyopathy (CC) is an important cause of heart failure and sudden cardiac death (SCD) in Latin America. Migratory movements have spread carriers throughout the world, especially in USA and Europe. Left Ventricle (LV) involvement is a landmark and apical aneurysm a pathognomical sign. Nevertheless, early involvement of the right(More)
Methods A total of 121 patients with CHD disease (52.1% female; 54.5 ± 13 years-old) from Ribeirao Preto Clinical Hospital (Sao Paulo, Brazil) were included. A CMR was performed at the enrollment from October/2009 to March/2013 in a single 1.5T scanner (Achieve, Phillips, the Netherlands), including SSFP cines at the vertical and horizontal long axis, and a(More)
OBJECTIVE To propose a protocol for pulmonary angiography using 64-slice multidetector computed tomography (64-MDCT) with 50 mL of iodinated contrast material, in an unselected patient population, as well as to evaluate vascular enhancement and image quality. MATERIALS AND METHODS We evaluated 29 patients (22-86 years of age). The body mass index ranged(More)
Background Chagas’ disease (CD) is caused by the protozoan parasite Trypanosoma cruzi leading to a lifelong infection, which is still recognized as one of the world’s most neglected tropical diseases. After an acute phase, which is commonly unapparent, 30-40% of the patients develop the chronic form and chronic Chagas ‘cardiomyopathy (CCC), its most serious(More)
BACKGROUND Right ventricular (RV) impairment is postulated to be responsible for prominent systemic congestion in Chagas disease. However, occurrence of primary RV dysfunction in Chagas disease remains controversial. We aimed to study RV systolic function in patients with Chagas disease using cardiac magnetic resonance. METHODS AND RESULTS This(More)
Background The precise quantification of aortic regurgitation (AR) is central to surgical planning. Some authors suggest early intervention in asymptomatic patients with severe AR. With the advent of transcatheter aortic valve implantation (TAVI), the identification and precise quantification of paravalvular regurgitation is also paramount. In routine(More)
Background Myocardial fibrosis as detected by late gadolinium enhancement (LGE) has been linked to adverse prognosis in several cardiovascular diseases. In aortic stenosis, LGE has been linked to worse systolic function and prognosis. In aortic regurgitation (AR), LGE has only been described in small experimental and clinical trials. Objectives: To evaluate(More)
