P319Is the measurement of QRS duration valid and reproducible in patients with left bundle branch block?

Prognostic value of pulmonary vascular resistance estimated by cardiac magnetic resonance in patients with chronic heart failure.

Pulmonary arterial hypertension is known to be related to worse prognosis in patients with heart failure (HF). Quantification of pulmonary vascular resistance (PVR) still requires invasive right heart catheterization. Recent studies have shown an accurate method for non-invasive estimation of PVR by cardiac magnetic resonance (CMR). Our aim was to evaluate the prognostic value of PVR calculated by CMR in patients with congestive HF.We calculated PVR by CMR in 132 patients [age 65.6 ± 13.1 years, left ventricular ejection fraction (LVEF) 35.1 ± 16.4%, ischaemic aetiology 40%] recently admitted for decompensated HF and derived to our cardiac imaging unit for diagnosis. Patients with cardiac e…

Isolated RV diverticulum: diagnosis by cardiac magnetic resonance and 3D TEE

A 16-year-old male was referred to our hospital because of exertional chest pain. There was no personal or family history of any cardiovascular disease. Findings on physical examination and vital signs were normal. An ECG showed a right bundle superoanterior zonal block pattern with low potentials in frontal plane and intraventricular conduction delay (QRS Complex 120 msg) with pseudo-epsilon wave in V1 …

[Diagnostic performance of surface electrocardiogram in early detection of chagasic cardiomyopathy].

Contrast-enhanced cardiac magnetic resonance imaging (CMR) allows early detection of myocardial involvement by Trypanosoma cruzi infection. The aim of our study was to assess the diagnostic performance of the surface electrocardiogram (ECG) in the early detection of Chagas' cardiomyopathy (CCM) compared with CMR.We included 43 asymptomatic patients (30 women, 42 ± 9.8 years), diagnosed of Chagas disease. The sample was divided into 2 groups according to the presence (n=17) or absence (n=26) of electrocardiographic abnormalities. All patients underwent CMR and late gadolinium enhancement (LGE) was used as a marker of early myocardial involvement.Six (14%) patients had a LGE significantly hig…

Gerbode-type left ventricular outflow tract to right atrial fistula complicating prosthetic aortic valve replacement identified by cardiac computed tomographic angiography

Abstract Acquired left ventricular-right atrial communication ( Gerbode-type defect) is a rare complication of infective endocarditis. Although transesophageal echocardiography remains the technique of choice for the evaluation of complications of endocarditis this case highlights the usefulness of cardiac computed tomography in this scenario, particularly in cases where assessment of coronary anatomy is required before surgery.

Incidental finding of migrated pacing lead fragment into pulmonary artery detected with CT

This case shows a rare complication of a migrated atrial lead into the pulmonary artery incidentally detected during a comprehensive evaluation of coronary CT angiography.
