PG - 3797-801 LID - S0167-5273(13)01090-5 [pii] LID - 10.1016/j.ijcard.2013.06.036 [doi] AB - BACKGROUND: Pulmonary arterial hypertension (PAH) after shunt closure is associated with a poor prognosis. The aim of this study was to assess retrospectively the hemodynamics of patients developing PAH after shunt closure. METHODS: Hemodynamic data obtained by right heart catheterization (RHC) performed at baseline and after shunt closure were analyzed. RESULTS: Twenty-two patients, 13 with atrial septal defect (ASD), 6 with ventricular septal defect (VSD), 1 with patent ductus arteriosus, 1 with both ASD and VSD, and 1 with complete atrio-ventricular canal have been considered. The mean age at closure was 25.3+/-20.1 years (range of 3 months to 56.7 years), and the mean age at PAH diagnosis was 37.0+/-20.8 years (range of 5 to 61.2 years). The time delay between shunt closure and PAH diagnosis was 140.2+/-100.2 months. At baseline RHC, hemodynamic data were as follows: pulmonary vascular resistance (PVR) of 8.6+/-2.6 Wood units, PVR index (PVRi) of 10.1+/-2.7 Wood units *m(2), mean pulmonary arterial pressure of 43.7+/-9.7 mmHg, PVR to systemic vascular resistance ratio (PVR/SVR) of 0.70+/-0.23, and Qp/Qs of 1.6+/-0.4. In particular, 18/22 (81%) had PVR>/=5 Wood units, 21/22 (95%) PVRi>/=6 Wood units *m(2), 21/22 (95%) PVR/SVR>/=0.33, and 11/22 (50%) Qp/Qs/=5 Wood units), PVRi (>/=6 Wood units *m(2)) and PVR/SVR (>/=0.33) are common findings in patients who develop PAH late after shunt closure. Large prospective clinical trials are needed to establish the safe limits for shunt closure. CI - (c) 2013.
