BACKGROUND In patients with mitral regurgitation (MR), assessment of the severity of valvular dysfunction is crucial. Recently, regurgitant orifice area has been proposed as the most useful indicator of the severity of MR. The purpose of our study was to determine whether planimetry of the anatomic regurgitant orifice (ARO) in patients with MR is feasible(More)
AIMS Plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) is a strong biochemical marker of heart failure and left ventricular dysfunction (LVD). Due to renal arterio-venous clearance of NT-proBNP and the correlation of plasma concentrations with renal function, we hypothesized that NT-proBNP may have potential as a urinary marker. The objective of(More)
BACKGROUND Troponin T is an established marker of myocardial ischemia. We speculated that the role of the new high-sensitive troponin T (hs-cTnT) might expand towards non-ischemic myocardial disease, indicate disease severity and allow for prognostication in chronic heart failure. METHODS Hs-cTnT (Roche Diagnostics, Mannheim, Germany) was assessed in 233(More)
OBJECTIVE To compare the extent and distribution of focal fibrosis by gadolinium contrast-enhanced magnetic resonance imaging (MRI; delayed hyperenhancement) in severe left ventricular (LV) hypertrophy in patients with pressure overload caused by aortic stenosis (AS) and with genetically determined hypertrophic cardiomyopathy (HCM). METHODS 44 patients(More)
Atrial septum defects (ASDs), ventricular septum defects (VSDs) and patent ductus arteriosus (PDA) are the most common adult congenital heart defects. The degree of left-to-right shunting as assessed by the ratio of flow in the pulmonary (Qp) and systemic circulation (Qs) is crucial in the management of these conditions. This study compared phase-contrast(More)
OBJECTIVE Gastrointestinal stromal tumors (GISTs) are uncommon mesenchymal tumors of the gastrointestinal tract. Fine needle aspiration (FNA) is one option for diagnosing GISTs before surgery. This study was designed to evaluate the clinical utility of FNA in the diagnosis of GISTs. STUDY DESIGN FNAs from 19 GISTs originating in the stomach, small bowel(More)
AIMS Sleep-disordered breathing (SDB) may be a risk factor for expansion of infarct size early after acute myocardial infarction (MI) by exposing the heart to repetitive oxygen desaturations and increased cardiac afterload. The objective of this study was to assess the impact of SDB on myocardial salvage and infarct size within 3 months after acute MI. (More)
PURPOSE We sought to determine whether noninvasive planimetry by magnetic resonance imaging (MRI) is suitably sensitive and reliable for visualizing the mitral valve area (MVA) and for detecting increases in the MVA after percutaneous balloon mitral valvuloplasty (PBMV). MATERIALS AND METHODS In 8 patients with mitral valve stenosis, planimetry of the MVA(More)
BACKGROUND Left ventricular hypertrophy (LVH) is a hallmark of chronic pressure or volume overload of the left ventricle and is associated with risk of cardiovascular morbidity and mortality. The purpose was to evaluate different electrocardiographic criteria for LVH as determined by cardiovascular magnetic resonance (CMR). Additionally, the effects of(More)
BACKGROUND The aim of the study was to determine whether noninvasive planimetry of aortic valve area (AVA) by magnetic resonance imaging (MRI) is feasible and reliable in patients with valvular aortic stenosis in comparison to transesophageal echocardiography (TEE) and catheterization. METHODS AND RESULTS Planimetry of AVA by MRI (MRI-AVA) was performed(More)
