New 3D images of arteries help cardiologists evaluate chest pain

New 3D images of arteries help cardiologists evaluate chest pain


OPTIMISTIC THE OUTBREAK CAN BE
STOPPED BEFORE IT SPREADS
FURTHER. EMILY: 5 ON YOUR HEALTH TONIGHT,
DIAGNOSING CHEST PAIN. SOME TESTS ARE INVASIVE AND
CARRY RISKS. BUT NEW TECHNOLOGY AT ONE BOSTON
HOSPITAL IS MAKING IT EASIER FOR
DOCTORS TO SEE WHAT’S REALLY
HAPPENING TO THE HEART
>>YOU CAN SEE HOW LUMPY BUMPY
THEY ARE. EMILY: DR. JAMES UDELSON HAS
SEEN PLENTY OF HEART TROUBLE
BEFORE, BUT THIS VIEW IS NEW.>>THOSE ARE CHOLESTEROL
BLOCKAGES. EMILY: UNLIKE A TRADITIONAL
CAT-SCAN, THIS 3-D IMAGE SHOWS
WHAT’S HAPPENING INSIDE THE
ARTERIES
IF THE BLOOD FLOW IS TOO SLOW,
THE PATIENT CAN EXPERIENCE CHEST PAIN, AND IN SOME CASES, A HEART
ATTACK.>>THIS WOULD BE YOUR GUIDE AS
TO WHICH BLOCKAGE. — WHICH BLOCKAGE WAS CAUSING
THE PROBLEM. EMILY: IT’S A NEW PROCESS CALLED
HEART-FLOW ANALYSIS. AND TUFTS MEDICAL CENTER IS THE
FIRST HOSPITAL IN BOSTON TO
START USING IT.>>WE’VE NEVER BEEN ABLE TO
MEASURE BLOOD FLOW DIRECTLY
WITHOUT DOING AN INVASIVE
PROCEDURE. AND THE BLOOD FLOW DATA THAT
COMES FROM THE HEARTFLOW
TECHNOLOGY IS QUITE SIMILAR TO
THE INVASIVE CATHETERIZATION
DATA. EMILY: HEART DISEASE IS THE
NUMBER ONE KILLER FOR BOTH MEN
AND WOMEN IN THE U.S. SO FIGURING OUT NEW WAYS TO
EVALUATE BLOCKAGES SAFELY AND
QUICKLY BEFORE THEY BECO
DEADLY IS CRITICAL. WITH HEARTFLOW, A CARDIOLOGIST
SENDS THE PATIENT TO RADIOLOGY
FOR A CAT-SCAN USING THIS NEW
SUPER-FAST MACHINE.>>THEY ARE ABLE TO FREEZE THE
HEART MOTION AND TAKE A SCAN OF
THE WHOLE HEART. IN THE TIME A PATIENT CAN HOLD
THEIR BREATH. EMILY: THE RADIOLOGIST SENDS
THOSE PICTURES TO HEART-FLOW,
WHICH USES THEM TO BUILD A 3-D
MODEL OF THE PATIENT’S HEART. — PATIENT’S ARTERIES. THE COMPANY THEN APPLIES THE
PRINCIPLES OF FLUID DYNAMICS TO
SIMULATE BLOOD FLOW, AND MEASURE
EXACTLY WHERE IT SLOWS DOWN.>>SO WITH THIS TEST, WE CAN
REALLY BE VERY PRECISE ON TH
CLINICAL SIGNIFICANCE OF EACH
INDIVIDUAL BLOCKAGE. EMILY: WITHIN HOURS, THE RESULTS
ARE IN.>>THIS IS VERY ABNORMAL BLOOD
FLOW INDICATING THAT THE
BLOCKAGES UP HERE ARE VERY
SIGNIFICANT. EMILY: IN THIS CASE, DR. UDELS
WOULD RECOMMEND MORE TESTING,
THEN POSSIBLY A STENT OR BYPASS
SURGERY TO OPEN THE ARTERY.>>BUT FOR THE OTHER 90% WHO
AREN’T AT RISK, YOU CAN RAPIDLY
FIGURE THAT OUT AND SEND THEM
HOME. EMILY: RIGHT NOW AT TUFTS,
HEART-FLOW IS ONLY AVAILABLE TO
CARDIOLOGY PATIENTS. BUT DOCTORS IN THE EMERGENCY
ROOM MAY BE ABLE TO USE
