Pulmonary artery hypertension following coronary artery bypass grafting: a case report.

Post-operative pulmonary complications in coronary artery bypass grafting (CABG) surgery are mostly reversible. We report a patient who developed pulmonary arterial hypertension (PAH) post-CABG and did not have pulmonary hypertension prior to surgery. PAH Group 1 was diagnosed after right and left heart catheterization. To the best of our knowledge, this is the only reported case of a patient developing PAH post-CABG surgery. This could be explained by immunological and/or haemostatic changes triggered by cardiopulmonary bypass. We hope that as more knowledge is gained regarding the pathophysiology of PAH, cases like these could be better understood.
