Cheney had suffered three heart attacks in 10 years, his first at age 37, and in 1988 underwent quadruple-bypass surgery to relieve blockages in his coronary arteries.
In the procedure, a catheter system, guided by ultrasound was inserted into an artery in the leg then threaded up through the aorta and into the coronary arteries.

In PCI, a catheter is passed usually from the femoral artery in the groin up to the heart and into the small coronary arteries that pass through the heart muscle.
Last year, researchers published a study suggesting the device could help prevent small heart attacks that occasionally occur in about 10% of procedures when stents are deployed to prop open diseased coronary arteries.
The stress thallium and the cardio catheterization, in which dye is injected in the coronary arteries (arteries of the heart muscle) are both useful in telling us if there is any coronary artery disease.
Dr. Robert Bonow, chief of cardiology at Northwestern University's Feinberg School of Medicine, notes that about 10 percent of study participants with a positive test had normal coronary arteries, and 17 percent of those with a normal test had coronary disease.
Additional tests may include a nuclear stress test to assess for blockages in the coronary arteries, and if positive, a cardiac catheterization, an invasive test which involves threading a thin wire into the heart to assess for blockages in the coronary arteries as well.
Steven Nissen, the chairman of cardiology at the Cleveland Clinic and head of the American College of Cardiology, will present one key study that will use ultrasound probes to measure the effect of torcetrapib on plaque in the coronary arteries at the ACC meeting in New Orleans next March.
Used diagnostically in patients with coronary artery disease to determine which arteries should receive a stent, it involves inserting a guide wire that measures pressure into the artery instead of relying solely on the traditional coronary angiogram.
