	1	Exercise Catheterization for Hemodynamic Evaluation of Adults with Coarctation of the Aorta显示文摘Background: Coarctation of the aorta (CoA) is associated with a generalized arteriopathy and long-term complicationsdespite repair. Data on invasive exercise hemodynamics in this population are lacking. Accordingly, wereviewed adults with CoA undergoing exercise catheterization to assess 1. hemodynamic profile;2. feasibilityfor assessment of CoA severity. Methods: Twenty patients undergoing exercise cardiac catheterization (12 armadduction and 8 supine cycle ergometry) at a quaternary care center between 2004 and 2021 were identified. Restingand exercise hemodynamic data were abstracted from the procedure logs. Results: Mean age was 43.6 ±12.0 years. Eleven patients (55%) had resting pulmonary arterial wedge pressure (PAWP) >15 mmHg;amongthose undergoing arterial catheterization, left ventricular end-diastolic pressure was >15 mmHg in 63%. Elevenpatients (55%) had pulmonary hypertension: 7 (35%) combined and 4 (20%) isolated post-capillary. At peak exercise,ΔPAWP/Δcardiac output (CO) ≥2 and Δmean pulmonary artery pressure/ΔCO ≥3 mmHg/l/min were foundin 7 (78%) and 6 (67%) patients, respectively;the composite of exercise PAWP ≥25 mmHg or ΔPAWP/ΔCO>2 was seen in 12 (86%). CoA peak-to-peak gradients at baseline (n = 14) and during exercise (n = 9) were 12(3–16) and 16 mmHg (9–28), respectively. Only 2 patients had an increase in CoA gradient to >20 mmHg withexercise. Conclusions: Diastolic dysfunction and pulmonary hypertension were highly prevalent, with exerciseunmasking abnormal diastolic and pulmonary vascular reserve in some individuals. Most patients failed to showsignificant increases in CoA peak-to-peak gradients with exercise. Further studies are warranted to establish thebest diagnostic method for CoA severity assessment.
