Heart Lung Catheter System Helps Patients Avoid Open Heart Surgery

New technology is allowing cardiologists to do life-saving procedures on high- risk patients too sick to undergo open heart surgery. The heart lung catheter system called TandemLife works to pump blood to keep the body functioning while doctors stabilize patients. 

Last year, Ann Martin didn’t feel quite right, so she went to the hospital.

"They zipped me in there and did an EKG first which did identify that I was having a heart attack," Martin said.

She had angioplasty but didn’t want surgery to relieve her blocked arteries. Then, while getting a second opinion at another medical center she had a second heart attack.

"If she had not come, I don’t think she would have made it this time," said Dr. Kapil Lotun, Director of the Cardiac Catheterization Lab at Banner-University Medical Center.

Interventional cardiologist Lotun says Martin had 99 percent blockage on both sides of her heart. Surgery would have been high risk. So although he’d never used it in this procedure, Lotun says it made sense to use the TandemLife heart and lung catheter system.

"It takes over the function of the heart so that you have blood with oxygen going to the brain, your organs, and your tissues," Lotun explained.

The console powers this pump.

"This is the cannula which is from the vein going to the pump," Lotun said.

The pump pulls blood from a vein, oxygenates it and puts the blood back into the body.  It allowed Lotun to place stents and balloons in Martin’s arteries without using a breathing machine or invasive surgery.

“They put in five stents including a y-shaped one. A year later, I’m still going strong,” Martin stated.

She says her arthritis is what limits her activities more than her heart these days. And she feels blessed.

Cardiologists can put the TandemLife system in place before the procedure for high-risk patients like Martin. But Lotun says it’s always in the cath lab and can be activated in five to ten minutes if the need arises during other procedures.
