Left ventricular atrioventricular plane displacement: An echocardiographic technique for rapid assessment of prognosis in heart failure

Abstract

Objective - To assess the prognostic value of atrioventricular plane displacement in heart failure patients. Design - Patients were followed prospectively for one year after atrioventricular plane displacement determination. Setting - Malmo University Hospital, with a primary catchment area of 250 000 inhabitants. Patients - 181 patients with a clinical diagnosis of heart failure; age 75.7 (SD 5.2) years, duration of heart failure 2.7 (5.7) years; 100 men, 81 women. Main outcome measures - Mortality in relation to atrioventrieular plane displacement. Results - Total mortality was 22.7% (41/181), and was highly significantly (P = 0.001) related to atrioventricular plane displacement. Mortality within prospectively defined categories of displacement was: ≤ 10.0 mm, 0% (0/19); 8-2 to 9.9 mm, 10.3% (3/29); 6.4 to 8.1 mm, 19.4% (12/62); and < 6.4 mm, 36.6% (26/71). The groups were similar in age, sex, angiotensin converting enzyme inhibitor and β blocker treatment, and cause and duration of heart failure. Conclusions - Mortality in heart failure is strongly related to atrioventricular plane displacement.
