Heart Problems Claim Thoroughbred Stallion Dynaformer

One of Thoroughbred racing's premier stallions, Dynaformer, died at the age of 27 at Robert and Blythe Clay's Three Chimneys Farm, in Versailles, Ky., on April 29.

The stallion, known internationally for siring such top class athletes as Kentucky Derby (gr. I) winner Barbaro, Melbourne Cup (Aus-I) winner Americain, and $4.7 million dollar-earner Perfect Drift, had been pensioned after suffering an aortic valve rupture the afternoon of April 14 while in his stall.

An ultrasound performed the following day revealed several holes in Dynaformer's heart as a result of the cardiac event, one measuring eight centimeters long and two others measuring two centimeters each.

Dynaformer had been resting comfortably, eating well, and maintaining his daily turnout routine in the days following the scare, but his health took a turn the evening of April 28.

"Dynaformer told us when it was his time to go," said Jim Morehead, DVM, Three Chimneys' resident veterinarian. "Amazingly, he had been comfortable after his initial crisis on April 14 and had been able to go to his paddock daily. A normal horse would not have survived his initial cardiac episode. He did everything on his terms, including deciding when he'd had enough."

The public is invited to pay their respects to Dynaformer during the annual Three Chimneys Derby Week Open House on May 4 from 10 a.m. until 1 p.m. A memorial service for Dynaformer will be held at 12:30 p.m. in the stallion cemetery.

Dynaformer's death came on what would have been the ninth birthday of his most famous son, Barbaro. The stallion will be buried in the Three Chimneys stallion cemetery next to stablemates Rahy and Wild Again.

Bred in Kentucky, Dynaformer was raced by his breeder, Joseph Allen and was trained by D. Wayne Lukas. During his race career, he won the 1988 Jersey Derby (gr. II), Discovery Handicap (gr. II), and Lucky Draw Stakes at 3. Dynaformer, who is out of the His Majesty mare Andover Way, retired from racing with a record of 7-5-2 from 30 starts, for earnings of $671,207.
