Texas heart surgeon

Dr. Denton Cooley, a Texas surgeon who performed some of the earliest heart transplants and implanted the world’s first artificial heart, has died.

Linden Emerson, a spokeswoman for the Texas Heart Institute in Houston, says Cooley died on Friday. He was 96.

In 1969, Cooley implanted the world’s first artificial heart as a temporary measure while a heart transplant was arranged. A year earlier, he had performed the first successful human heart transplant in the U.S.

Cooley contributed to the development of techniques to repair and replace diseased heart valves and was renowned for operations to correct congenital heart problems in infants and children.

Before Kybella became available, doctors offered liposuction or a direct incision as options for double chin improvement, but both are invasive, carry more risks and side effects and include significant downtime.

Kybella is a more benign option, though it does involve injections and possible side effects. In clinical trials, 4.3 percent of participants experienced temporary nerve paralysis as a side effect.

If the solution is injected superficially, the hair follicles can be damaged and result in bald areas, or a skin sore that will heal. Numbness can last up to six weeks.

Some patients may also feel as though they have difficulty swallowing or even breathing after the treatment, but it’s a mental perception, not a physical side effect, Russo said.

What’s most attractive to men about Kybella is that there is little to no downtime before they can resume their normal activities.

“They want to come in, get it done and be back to work the next day,” Burgdorf said.
