Pulmonary valve injury: Swan-Ganz or surgery.
Pulmonary artery catheter (PAC) is a commonly used monitor in cardiac surgery. Pulmonary valve injury from the balloon of the pulmonary artery catheter is exceedingly rare; its description by transesophageal echocardiography is nonexistent in the literature. A patient is reported who developed a flail anterior pulmonary leaflet several days after successful myectomy for hypertrophic cardiomyopathy. The temporal sequence of PAC use and four transesophageal echocardiography studies over 13 days, with the first three showing normal pulmonary valves, suggested pulmonary valve trauma, most likely from a Swan-Ganz catheter, as the etiology. Partial damage to the pulmonary valve from the original surgery may have predisposed the patient to further damage when the PAC was reintroduced in the intensive care unit.
