However, the CVP waveform was noted to be abnormal ( Fig. 1 ).
Intraoperative transesophageal echocardiogram (TEE) showing the pulmonary artery (PA) catheter (yellow circle) exiting the coronary sinus (yellow lines) into the right atrium. The coronary sinus diameter was 1.29 cm. CS, coronary sinus; RA, right atrium; RV, right ventricle.
