content: In the early 1950s a Swedish medical team showed that echocardiography could detect a narrowed or stenotic mitral valve. In time, ultrasound became a routine diagnostic technique. Yet clear images of the heart and its vessels were hard to achieve in patients with chronic obstructive pulmonary disease, obesity or a barrel chest. To overcome this problem, Dr. Leon Jay Frazin (1942-), a cardiology fellow at the Texas Heart Institute, developed an Esophageal Echocardiograph transducer that, when swallowed by a patient, produced clear images of the interior of the heart.
