In chronic mitral regurgitation (MR) left atrium is one of the first cardiac structures that is involved in remodeling and ultrastructural changes for a progressive volume overload. Severe left atrial (LA) dilation on echocardiography and new onset of atrial fibrillation in asymptomatic patients with preserved Left Ventricular (LV) function, appeared as a Class IIb recommendation for considerat...
drug therapy, but not so after adjustment for left ventricular ejection fraction, left atrial diameter or duration of atrial fibrillation. We feel that our results justify the conclusion that “patients who undergo electrical cardioversion display a greater degree and longer duration of mechanical atrial dysfunction than those who convert pharmacologically or spontaneously” (1). We agree with Fa...
Left atrial function was evaluated in patients with and without remote myocardial infarction. The simultaneous left atrial pressure recording and left atrial and left ventricular cineangiograms were obtained with a catheter-tip micromanometer. The pressure-volume curve of the left atrium was composed of an A-loop and a V-loop. The ratio of active atrial emptying to left ventricular stroke volum...
Sepsis is defined as a dysregulated host response to several types of infections [1], still representing challenging issue in Medicine. Atrial Fibrillation (AF) frequently occurs patients with sepsis and septic shock [2], one difficult challenge for treating physicians: increased heart rate loss atrial kick worsen myocardial function cardiac output [3]. Unsurprisingly, AF has been consistently ...
