Chordae tendineae rupture: a rare cause of tricuspid regurgitation following coronary artery bypass grafting.

ABSTRACT:

Background

Tricuspid regurgitation is classified broadly by its etiology being either structural or functional. New or worsening tricuspid regurgitation upon weaning from cardiopulmonary bypass is rare and often functional. However, iatrogenic structural causes are possible and should be investigated with a high index of suspicion when issues separating from cardiopulmonary bypass arise. Currently, isolated coronary artery bypass grafting is not a class I indication for intraoperative transesophageal echocardiography, leading to significant practice variation. However, intraoperative transesophageal echocardiography, even during routine isolated coronary artery bypass grafting, can be a valuable tool in differentiating between functional and structural causes of post-cardiopulmonar
