Systolic atrioventricular plane displacement (AVPD) in patients with preserved LV systolic function

Preserved fractional shorteningPreserved LV ejection fraction by Simpson's biplane method
Systolic AVPD (mm)≥25% (55/82)≥30% (34/82)≥ 35% (68/95)≥ 40% (57/95)Preserved LV systolic function by “eyeball” assessment (109/131)
Total number of patients referred with suspected heart failure was 147. Two had valve disease alone, 10 had atrial fibrillation alone, and four had valve disease and atrial fibrillation. The total number of patients studied was 131. Forty nine had no measureable fractional shortening (therefore, n = 82 for fractional shortening (82 + 49 = 131)). Thirty six had no ejection fraction measureable by Simpson's biplane method (therefore n = 95 for ejection fraction by Simpson's biplane method (95 + 36 = 131)). Fifteen had no measureable AVPD.
