TEE (midesophageal 4-chamber long-axis view) showing air in the LA and LV

This TEE midesophageal 4-chamber long-axis video recorded prior to weaning from cardiopulmonary bypass shows air in the LA and LV, noted as echo-dense targets in these chambers of the heart. Note that color flow Doppler imaging shows significant tricuspid regurgitation and right atrial distention that result from acute right ventricular dysfunction owing to right coronary artery air embolism.
