Cardiothoracic VAD Program<br />

Expands with New Technology<br />

A ventricular assist device (VAD) is an artificial<br />

heart pump utilized for patients recovering from<br />

heart attacks or heart surgery or those who suffer<br />

from congestive heart failure. Initially, VADs<br />

were developed for short term use. However, in<br />

the last few years, VAD technology has improved<br />

substantially and their use has been extended to<br />

patients who need long term support. The VAD<br />

program has been growing since 2009 as more<br />

reliable and long lasting pumps are introduced<br />

into the market, battery technology is improving<br />

and fewer complications are arising with the VADs. Dr. Song also mentions<br />

that because of the improved safety of the procedure, surgeons are able offer the<br />

therapy to a broader range of patients.<br />

A major transition in the use of the VAD is that older or chronically ill patients<br />

who are poor transplant candidates can now actually live with a VAD for<br />

years as destination therapy. Due to increased demand, a team of providers<br />

has been formed to support the VAD program. Three VAD coordinators have<br />

joinedand the cardiothoracic surgery faculty has grown. Another component<br />

of VAD development is research. Dr. Song, his faculty and other researchers are<br />

committed to investigating the outcomes associated with their patients. They<br />

are engaged in outcomes based studies that analyze which patients are the best<br />

candidates for a VAD. Currently, OHSU is involved in a pivotal HEARTWARE<br />

device trial and a Heart Mate 2 Trial investigating VAD outcomes in patients with<br />

ambulatory heart failure.<br />

Dr. Song notes that the program faces challenges in its goals to be involved with<br />

emerging technology that pushes the field ahead and to ultimately make surgery<br />

safer. In several years, his team will be able to insert completely implantable VADs,<br />

in which the battery of the VAD will no longer be tethered to a wall charger and<br />

can be charged within one’s body. He explains that as the need for VADs expands<br />

it could be difficult to ensure that the infrastructure is in place to look after<br />

the growing<br />

population of<br />

these patients.<br />

5th Annual Esophageal<br />

Cancer Research Dinner<br />

The 5th Annual Esophageal Cancer Research<br />

Dinner was held at Andina Restaurant in Portland<br />

on January 11, 2013. The event honored the 1st<br />

Annual Michael J. Newton Foundation Award<br />

winners. The dinner is attended by physicians from<br />

different specialties involved in the esophageal<br />

cancer patient care, the esophageal cancer research<br />

team, the esophageal cancer research forum<br />

speakers, visiting professors, esophageal cancer<br />

patient’s survivors and their significant others.<br />

The evening serves as an excellent opportunity<br />

for esophageal cancer survivors and their families<br />

to interact with other patients, physicians and<br />

the research team in an informal and friendly<br />

environment. Patients not only exchange personal<br />

experiences and histories, but they get a sense of<br />

the efforts that result in a better understanding and<br />

treatment in relation to their disease.<br />

The program has<br />

achieved many accomplishments in the past few years including numerous<br />

papers showcasing outcomes data that were presented at national meetings.<br />

Dr. Song and his team have also helped hundreds of patients and provided<br />

ongoing care long after the patient’s initial surgery. Another accomplishment<br />

is their commitment to educating cardiologists and providers throughout<br />

the region who are now using the new VAD technology with their patients<br />

and improving quality of life. Dr. Song is excited about the future of VADs<br />

and strives to continue to offer the most advanced treatments in heart failure<br />

while pursuing research and development that improves surgical outcomes<br />

and safety.
