AIM: The aim of the present study was to investigate if left atrioventricular plane displacement (AVPD) has a prognostic value in patients with atrial fibrillation.
METHODS AND RESULTS: Left AVPD was assessed by two-dimensionally guided M-mode echocardiography in the four- and two-chamber views in 160 consecutive patients with chronic atrial fibrillation, who were followed up with regard to mortality for an average of 45 months. All-cause mortality during follow-up was 49% (n=78). AVPD was lower in patients who died compared to those who survived: 6.6+/-1.7 versus 7.5+/-1.7 mm, P=0.0005. In 49 patients (31%), death was due to chronic heart failure or acute myocardial infarction. Among those who died of cardiac events, AVPD was 6.3+/-1.6 mm, versus 7.1+/-1.8 mm among those who died of other causes, P=0.0001. In multiple logistic regression analysis, AVPD (P=0.005), age (P=0.0005), and a history of chronic heart failure (P=0.004) correlated independently with mortality.
CONCLUSION: Left AVPD was clearly decreased in patients with atrial fibrillation. The decrease was most pronounced in patients who died of cardiac events, whereas it did not differ significantly between those who died of non-cardiac causes and those who survived. The discriminative value of left AVPD was limited.
