Transesophageal (tranz-ih-sof-uh-JEE-ul) echocardiography (EK-o-kar-de-OG-rah-fee), or TEE, is a test that uses sound waves to create high-quality moving pictures of the heart and its blood vessels. TEE is a type of echocardiography (echo). Echo shows the size and shape of the heart and how well the heart chambers and valves are working. Echo can pinpoint areas of heart muscle that aren't contracting well because of poor blood flow or injury from a previous heart attack.
Grand Prix: The highest level of show jumping. Run under International Federation for Equestrian Sports (FEI) rules, the horse jumps a course of 10 to 16 obstacles, with heights and spreads of up to 6.5 feet (2.0 m).
Dana now maintains a company that produces high dive shows. He was tied with the world record for highest dive at 52.4 m (172 ft) until 1985, when Randy Dickison (fracturing his leg in the process) set a record of 174 feet 8 inches at an event in Hong Kong. In 2015, the current record for a cliff jump (not qualifying as a high dive) of 58.8 m (193 ft) was set by Laso Schaller.
