Diastolic dysfunction and left atrial volume

Diastolic dysfunction and left atrial volume

OBJECTIVES We examined the association between diastolic function and left atrial volume indexed to body surface area (LAVi) in a population-based study. BACKGROUND Atrial enlargement has been suggested as a marker of the severity and duration of diastolic dysfunction (DD). However, the association between DD and atrial enlargement and their individual prognostic implications in the population ...

Impact of left ventricular diastolic dysfunction on left atrial volume and function: a volumetric analysis.

AIMS Diastolic dysfunction may result in elevation of left ventricular (LV) and atrial pressures, resulting in left atrial (LA) remodelling. We examined the effects of LV diastolic dysfunction on LA volume and function. METHODS AND RESULTS We measured LA volume and function in 83 patients with normal LV systolic function. The LV diastolic function grade was defined using traditional Doppler m...

Left ventricular diastolic dysfunction in atrial fibrillation

Left Atrial Diastolic Dysfunction following Catheter Ablation of Atrial Fibrillation.

Radiofrequency catheter ablation (RFCA)-induced thermal injury may cause and/or worsen left atrial (LA) diastolic dysfunction leading to pulmonary hypertension and heart failure in patients with atrial fibrillation (AF), the incidence of which is probably more common than is generally realized. Biplane 2-dimensional echocardiography coupled with tissue Doppler (velocity) imaging and Doppler-der...

Relationship Between Left Atrial Volume and Diastolic Dysfunction in 500 Brazilian Patients

BACKGROUND Left atrial volume index (LAVI) increase has been associated to left ventricle (LV) diastolic dysfunction (DD), a marker of cardiovascular events (atrial fibrillation, stroke, heart failure, death). OBJECTIVE To evaluate the relationship between LAVI and diferente grades od DD in Brazilian patients submitted to echocardiogram, studying LAVI increase determinants in this sample. M...
