Table 3.

Height and pressure differences between distal pressure sensor and catheter tip.

	Height differences (Pa–Pd) (mm)	(mmHg)
LAD (n=11)	−47.8 ± 14.6	3.7 ± 1.1
LCX (n=10)	+23.5 ± 8.5	1.8 ± 0.7
RCA (n=6)	+29.2 ± 9.4	2.3 ± 0.7

Data are expressed as mean ± SD. In the position where Pd is higher than Pa, it is represented by a minus sign, whereas in the position where Pd is lower than Pa, it is represented by a plus sign. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery; Pa, mean aortic; Pd, mean distal intracoronary pressure.
