Insights
Coronary artery bypass grafting (CABG) surgery rarely leads to pulmonary arterial hypertension (PAH). This case report details a patient who developed PAH after CABG, highlighting potential links to cardiopulmonary bypass.
Area of Science:
- Cardiology
- Pulmonology
- Surgical Complications
Background:
- Post-operative pulmonary complications after coronary artery bypass grafting (CABG) are typically reversible.
- Pulmonary arterial hypertension (PAH) is a serious condition affecting the arteries in the lungs and the right side of the heart.
Abstract:
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.
