Multidisciplinary Perioperative Management of Pulmonary Arterial Hypertension in Patients Undergoing Noncardiac Surgery

OBJECTIVES: To describe the effect of implementing a contemporary perioperative pulmonary hypertension (PH)-targeted protocol in patients with pulmonary arterial hypertension (PAH) undergoing noncardiac surgery (NCS). METHODS: The data of consecutive patients with PAH diagnosed by right heart catheterization who underwent NCS between January 1, 2006 and February 9, 2016 were reviewed. Patient demographics, etiology of PAH, clinical features, diagnostic data, utilization of PH-specific medications, and trend of perioperative complications rate were recorded during the study period. Most of the complications (70%) were related to general anesthesia. Two deaths (5%) occurred in our study group, both during the 2006-2011 period. CONCLUSIONS: The combination of a multidisciplinary perioperative approach, utilization of novel pulmonary vascular disease-targeted therapy, adequate perioperative optimization, and thoughtful selection of anesthetic technique seems to be a potential strategy to at least maintain similar perioperative outcomes among higher- and lower-risk patients with PAH undergoing NCS.
