Comparison of total TAPSE, TAPSERA, and TAPSERV in the PAH cohort before and after treatment
| PAH pretreatment group (N = 31) | PAH posttreatment group (N = 31) | ||||
|---|---|---|---|---|---|
| Mean ± SD | Interquartile range | Mean ± SD | Interquartile range | P | |
| TAPSE, cm | 1.7 ± 0.4 | 1.3–2.0 | 2.1 ± 0.4 | 1.9–2.4 | <0.0001 |
| TAPSERA, cm | 0.9 ± 0.3 | 0.7–1.1 | 1.1 ± 0.4 | 0.8–1.3 | 0.03 |
| TAPSERV, cm | 0.8 ± 0.3 | 0.6–1.0 | 1.1 ± 0.3 | 0.9–1.3 | 0.0003 |
| TAPSE due to RA systole, % | 51.2 ± 13.0 | 42.1–56.3 | 49.0 ± 12.8 | 40.0–54.5 | 0.43 |
Note
PAH: pulmonary arterial hypertension; RA: right atrial; TAPSE: tricuspid annular plane excursion; TAPSERA: TAPSE during RA contraction; TAPSERV: TAPSE before RA contraction.
