Experience with transesophageal echocardiography for mitral valve plasty in the remote stage after esophagectomy with gastric tube reconstruction via the posterior mediastinal route

Abstract

A 69-year-old male patient with mitral valve prolapse was scheduled for mitral valve plasty. Sixteen years earlier, he had undergone right open thoracotomy for esophageal cancer with subtotal esophagectomy, cervicothoraco-abdominal three-region dissection, posterior mediastinal tube reconstruction, and cervical anastomosis. Postoperatively, the patient had a treatment- and recurrence-free course, and an upper gastrointestinal endoscopy performed 2 years prior revealed no abnormality. We scheduled a transesophageal echocardiography for mitral valve surgery. We attempted to insert the probe but felt resistance at the height of the mid-thoracic region, and the image quality was poor, so we abandoned the intraoperative diagnosis. The surgery was performed as planned, and when the probe was manipulated again at the time of cardiopulmonary withdrawal, the mitral valve could be observed. The mitral valve was judged to be sufficiently repaired, and the surgery was terminated. There were no complications associated with transesophageal echocardiography.
