BREATHING WITH EMPHYSEMA
About three million Americans live with emphysema. Patients with severe forms of the disease can opt for surgery to cut off part of the lung -- but it can be risky. Now, there's an easier solution under study.

Robert Baker knows a thing or two about playing pool.
But a few months ago, even this simple hobby became difficult. Robert has emphysema.
Robert Baker
Has emphysema
"It became more and more difficult to breathe, and any exertion at all, and I'd be gasping for breath."
He couldn't even walk to get his mail.

"I couldn't go more than like 100 yards if that."
Emphysema happens when sacs in the lungs grow too big, and air gets trapped.

"So, they have over-inflated lungs, much like the Michelin Man on the inside."
Now, Doctor Jonathon Truwit is offering patients a new, nonsurgical option. Tiny valves like this one are implanted in the lungs - through a scope. The valves act like an umbrella. They prevent air from entering diseased sections of the lungs and redirect it to healthier areas.

"The air will hit the umbrella and get trapped by the umbrella and turn around and come out."
There's no incision, so the valve procedure is less risky than standard surgery -- and recovery is easier.

"I think it's terrific. I think we're offering opportunities for patients, should this work out, to have non, or a less invasive means of improving their quality of life."
Robert's felt the benefits.
Robert Baker
"I'm more energetic. I'm just healthier."
And today, he feels good enough to beat his wife at his favorite game.
The valve procedure has been performed on about 75 patients so far. There are safety risks. About 7 percent of patients suffer a collapsed lung. If patients experience problems, the valves can be removed. Doctor Truwit says the valves may offer an alternative to patients who are too sick to have standard lung surgery.
BACKGROUND: Emphysema is a condition in which there is over-inflation of structures in the lungs known as alveoli or air sacs. This over-inflation results from a breakdown of the walls of the alveoli, which causes breathlessness and a decrease in respiratory function. Damage to the air sacs is irreversible and results in permanent holes in the tissue of the lower lungs. Early symptoms of emphysema include shortness of breath and cough. The patient experiences great difficulty exhaling. Emphysema doesn't develop suddenly; it comes on gradually. Years of exposure to the irritation of cigarette smoke usually precede the development of emphysema.
Emphysema is the fourth most common cause of mortality in the U.S., according to the National Emphysema Foundation. Almost 3 million Americans live with the disease, and approximately 120,000 die each year.
STANDARD TREATMENT: Standard treatment for patients with emphysema includes:
- Quitting smoking: Experts say quitting smoking is the single most important factor for maintaining healthy lungs.
- Antibiotics: These can help treat bacterial infections, which are common among patients with emphysema.
- Bronchodilator drugs: These prescription drugs relax and open up air passages in the lungs. They may be inhaled or taken orally.
- Exercise: Doctors recommend breathing exercises to strengthen muscles.
- Lung transplantation: Recent studies have shown encouraging results for patients who undergo this procedure.
- Lung volume reduction surgery: Surgeons remove some of the more diseased portions of the lung. This increases available space in the chest cavity and allows the patient to breathe better.
NEW TREATMENT: Now, patients have one more non-surgical option for the treatment of emphysema. Jonathon Truwit, M.D., is the division head of the Division of Pulmonary and Critical Care Medicine at the University of Virginia in Charlottesville. He is studying a new procedure in which small valves block the entry of air into parts of the lungs that are affected by disease. Dr. Truwit implants the tiny valves while the patient is under anesthesia. Using a bronchoscope, he typically inserts six to nine of the valves. "We think the risk to the patient is going to be much lower because of the decreased operating room time and the decrease recovery time," says Dr. Truwit. "They can go out of the hospital the next day."
So far, the procedure has only been performed on about 75 patients across the country. "Their shortness of breath has been significantly reduced. Their quality of life has improved," he says. This surgery opens up one more option for patients who are not healthy enough to undergo a lung transplant or other surgical procedures for their emphysema. There are some risks, however. Approximately 7 percent of patients have suffered a collapsed lung.
