Duly Health and Care in suburban Chicago recently opened a new outpatient cardiac evaluation center equipped with a dedicated cardiac computed tomography (CT) system. It offers advanced CT imaging in an office setting. This is part of a trend in cardiology that is expected to greatly accelerate because of the 2021 chest pain evaluation guidelines released late last year. This gives cardiac CT a 1A level of evidence to be used as primary imaging modality. Duly is part of this shift toward office-based cardiac CT evaluations for more detailed cardiac screenings, evaluation of stable chest pain and pre-procedural structural heart workups.

The guidelines also gave a high rating for fractional flow reserve CT (FFR-CT). This technology uses the CT scan to create a computer model 3D coronary tree that shows hemodynamic pressure drops in each vessel segment to pinpoint culprit lesions or identify long-diffuse disease causing ischemia. Duly now routinely uses FFR-CT for any patient with a blockage of 30% or more. This can help determine if a patient needs to be revascularized in a cath lab or if they can be treated medically. 

The business model is designed to offer referring physicians in the Duly health system an alternative to sending patients to hospitals for full evaluations. This Lisle, Illinois, CT-equipped clinic is the first of its kind in the Midwest.

"We have been finding that as the technology of CT angiography has improved more and more over the years, we also are finding we are leaning on it more for diagnosis of coronary artery disease and chest pain syndromes in patients. We also found we were sending patients to the hospital environments to obtain that imaging, but we have had such a robust volume of cases for our large practice, we started investigating if it made sense to bring CT imaging in-house," explained Evans Pap­pas, MD, chair of the Duly Depart­ment of Car­di­ol­o­gy.

The GE Cardiographe scanner they installed is only half the size of conventional CT systems, but has much faster acquisition speeds to freeze the motion of the heart, even at higher heart rates, said Sujith Kalathiveetil, MD, FACC, Duly's direc­tor of cardiac imaging.

"The 2021 American College of Cardiology Chest Pain Guidelines really moved coronary CTA to become our first-line test for the evaluations of patients with chest pain with no previous diagnosis of coronary artery disease," Kalathiveetil said.

The technology uses AI and computational fluid dynamics to determine the hemodynamic flow inside the vessels. It color codes areas of reduced flow. The radiologist or cardiologist can pick any location along a vessel to see the FFR values. This can determine if a patient needs to be revascularized, or managed with medications.

The Cardiographe cardiac CT system was co-developed by GE Healthcare and Arineta. Its design included all the aspects of a CT scanner that are ideal for cardiac CT, and left out features included on workhorse CT systems for imaging other parts of the body. Both companies now sell the system. Arineta set up its own booth at RSNA 2021 because of a large amount of interest in its system after the ACC 2021 chest pain guidelines were released.
