Peripheral artery disease (PAD) causes narrowing of the peripheral arteries, most commonly in the arteries of the pelvis and legs. Commonly found in people with diabetes and smokers, PAD shares the same underlying causes as coronary artery disease and carotid artery disease. All cause reduced blood flow to organs supplied by the affected arteries.

When the arteries to the legs are affected exercise can increase the demand for blood flow beyond available supply resulting in a variety of painful symptoms and findings, including:
Intermittent claudication (a term that refers to impairment in walking, or pain, discomfort or tiredness in the legs that occurs during walking and is relieved by rest).

Severe insufficiency can cause pain at rest.

  • Leg numbness or weakness
  • Coldness in the leg or foot
  • Sores on the toes, feet or legs that heal poorly or don’t heal
  • A  change in color with redness when the legs are down and pallor when elevated
  • Hair loss or slow hair growth on the feet and legs
  • Slower toenail growth or thickened, deformed toenails
  • No pulse or a weak pulse in the legs or feet
  • Erectile dysfunction in men

All too often the symptoms of PAD progress to a point where a patient is told his or her only option is amputation. But in Southern Oregon, the Shaw Heart and Vascular Center has made great strides to ensure amputation is only a treatment of last resort, not a first option.

At Shaw Heart and Vascular Center, many patients originally considered for amputation are being treated with angioplasty, an effective non- surgical vessel-opening procedure.

Many people are familiar with angioplasty and stenting for narrowed heart arteries but are not aware of how effective, comfortable and relatively safe this procedure can be when applied in other circulations.

Instead of facing a scalpel and the loss of a toe, foot or entire lower leg, Shaw Heart and Vascular Center patients are treated using a catheter that is threaded through a vessel to the point of blockage. A tiny balloon at the tip of the catheter is inflated to clear the blockage and restore blood flow. A stent is often left in place to keep the vessel open.

Rather than enduring amputation and that procedure’s dramatically life-altering, and often life-threatening consequences, Shaw Heart patients often achieve relief from their PAD symptoms generally without even needing an overnight hospital stay. Many are up and walking the same afternoon and back at work in just a few days.

The benefits of treating PAD with angioplasty go beyond just saving a limb, says Howard Feldman, M.D., medical director of Shaw Heart and Vascular Center. The procedure can also be life saving. According to Dr. Feldman, some 25 percent of people with below-the-knee amputations are dead within a year, half within three years. Tragically, he adds, many of these amputations could be avoided.

Fewer than 25 percent of patients who have had a non-traumatic amputation have had an angiogram in advance,” Dr. Feldman says. “Without this information it is difficult to be certain that amputation is the only available, or the best, treatment option.

An angiogram is an X-ray study that enables physicians to visualize blood vessels and blood flow and determine precisely where a blockage is located. In the absence of an angiogram, an initial amputation of a toe, for example, may not even relieve the patient’s, leading to the amputation of another toe, then possibly the entire foot, and then higher up the leg until wound healing can occur.”

“Amputation is a permanent ‘solution’ to a potentially temporary problem”, Dr. Feldman says. “It is surprising how often it is avoidable.”

“Fortunately in our community we have cultivated good relationships with our surgeons and they understand that any patient who is being considered for amputation for PAD should first have an angiogram,” he says. “Through this simple step we have been able to identify many patients whose limbs, and sometimes lives, we can save through a procedure that we perform many times daily at Shaw Heart and Vascular Center.”

  • After just 10 days of having my stent, I’m back to work and about to hike the Sierra Nevadas with my husband. I know God, the ER and Shaw Heart were all watching out for me. If it hadn’t been for Shaw Heart, I wouldn’t be here.

Your heart has its own electrical system. Signals from this system regulate your heart’s rhythm. Normally the heart beats at an even, steady pace. However, if there is a problem with this electrical system, the heart may beat too fast, too slowly or in an irregular manner. Heart rhythm problems, called arrhythmias, can affect how well your heart is able to pump blood.

Patients who show symptoms of a rhythm problem, such as palpitations, lightheadedness, arrhythmias or fainting spells are often candidates for an electrophysiology (EP) study. This highly effective tool has been used for several years in larger metropolitan settings to help physicians locate areas within the heart that may be causing an abnormal rhythm and determine the best treatment.

Now EP studies are available at Shaw Heart and Vascular Center.


During an EP study, conducted in the Shaw Heart catheterization lab, physicians insert special electrode catheters (long, flexible wires) through a vein and into the heart. The catheters can sense electrical activity in different parts of the heart. They also can be used to deliver tiny electrical impulses to pace the heart (cause it to beat).


EP studies are generally done after other tests, such as electrocardiogram, echocardiogram and holter monitoring, have failed to provide the information needed to pinpoint the source of an abnormal heart rhythm. The EP study provides the most accurate and detailed information about how the heart’s electrical system is working.

In general, an EP study is done for one or more of the following reasons:

  • To diagnose the cause of symptoms.
  • To pinpoint the location of a known arrhythmia and decide the best treatment.
  • To see how severe an arrhythmia is and predict the risk of a future cardiac event, such as dying from a heart-related problem.
  • To determine how well medications are working to control an arrhythmia.
  • To decide whether an implantable device (such as a pacemaker or defibrillator) or a treatment procedure (such as catheter ablation) is necessary.


The results of EP studies help physicians prescribe the best treatment based on the type of arrhythmia, severity of symptoms and whether or not other heart problems are present. Treatment options include:

  • Cardiac Ablation:
    This is a procedure used to destroy, or ablate, parts of an abnormal electrical pathway that is casing a rapid heart rhythm. An ablation is sometimes performed during an EP study. During the procedure, doctors guide an ablation catheter into the heart close to the abnormal pathway. Radiofrequency energy is passed through the catheter to a small area of heart tissue where the fast heart rhythm may start or where abnormal pathways are located. The energy destroys only the problem cells so they can no longer send signals that are causing the irregular rhythms.
  • Anti-arrhythmic Drugs:
    Medications may help restore a normal heart rhythm and prevent arrhythmias from recurring. Most of these work by changing the pattern of electrical signals in the heart. This helps keep abnormal sites in the heart from starting rapid or irregular heart rhythms.
  • Pacemaker:
    A pacemaker is a small electronic device prescribed for people who have a slow heartbeat. It is implanted under the skin, usually in the upper chest, near the left or right shoulder, with leads attached to the heart. The pacemaker keeps track of the heart’s electrical activity and, when necessary, delivers electrical impulses that keep the heart beating at the proper pace.
  • Implantable Cardioverter-Defibrillator (ICD)
    The ICD is small electronic device prescribed for people who have had, or are at risk of having, dangerously rapid heart rhythms, or tachycardias. Implanted in the body, the ICD monitors heart rhythm at all times. If it senses a dangerously rapid rhythm, the device delivers pacing impulses or shocks to restore a normal rhythm.
