Background .– Tako-Tsubo cardiomyopathy (TTC) is characterized by transient stress induced transient left ventricular (LV) dysfunction. Right ventricular (RV) involvement may occur and is associated with bad outcome. Assessment of…
Introduction .– Conduction system disease and heart failure have a major impact on the prognosis of patients with myotonic dystrophy type 1 (DM1). An early detection of myocardial involvement could…
Background .– The cardiac consequences of aging and extensive athletic activity in men over the age of 50 years are unknown. Aims .– We intend to describe the adaptation of…
Background .– Heart failure (HF) with a preserved (P) left ventricular (LV) ejection fraction (EF) is common, though its diagnosis and physiopathology remain unclear. We sought to compare the myocardial…
Introduction .– It is well known that right ventricular pacing (VP) can alter left ventricular (LV) function. But few are known in ability of LV recovery after VP. Objectives .–…
Introduction .– The biplane Simpson remains the gold standard for the evaluation of left ventricular ejection fraction (LVEF). However, it allows only a semi-quantitative assessment of the myocardial function without…
Purpose .– To assess left ventricular (LV) twist mechanics in patients (pts) with tako-tsubo syndrome (TTS). Methods .– Two-dimensional strain and LV twist by speckle tracking echocardiography (echoPACK 7 version…
Aim .– Right ventricular (RV) function is a major determinant of prognosis in patients (pts) with congenital heart diseases (CHD), but its evaluation remains challenging. We evaluate feasibility and reproducibility…
Objectives .– To study the feasibility of quantifying left ventricular (LV) function by 2D-speckle tracking of myocardial deformation during exercise echocardiography in normal subjects. Background .– Accurate assessment of LV…
Introduction .– Stroke volume (SV-ETT) is hitherto evaluated by transthoracical Doppler (TTE) as: (circular) cross sectional area(CSAO) × velocity time integral (VTI). Cardiac output (CO) can thereof be derived as:…
