Supports TEE for unexplained CPB collapse; hypothesis-generating case report leaving prospective validation open.
We report a case of hemodynamic collapse during pulmonary embolectomy with cardiopulmonary bypass. The hemodynamic collapse was due to complete loss of venous return due to thromboembolic occlusion of the atrial cannula. The diagnosis was made during focused intraoperative transesophageal echocardiography.
