Figure 4. TAPSE/PASP ratio in patients with secondary MR
(A) A patient with severe secondary MR, TAPSE of 20 mm and PASP of 32.37 mmHg. This patient had a TAPSE/PASP ratio of 0.62 (more preserved RV-PA coupling) and did not die during follow-up. (B) A patient with severe secondary MR, TAPSE of 17 mm and PASP of 67.55 mmHg. This patient had a TAPSE/PASP ratio of 0.25 (more impaired RV-PA coupling) and died during follow-up. Despite both patients having preserved RV function according to TAPSE, the TAPSE/ PASP ratio and outcome were significantly different. MR = mitral regurgitation; PA = pulmonary arterial; PASP = pulmonary artery systolic pressure; RV = right ventricular; TAPSE = tricuspid annular plane systolic excursion.
