Researchers at Mass General are leading the first optical coherence tomography (OCT) registry, an international database of 3,000 patients who have received OCT. Optical coherence tomography is an intravascular imaging technique that may help physicians identify the vulnerable plaques that lead to heart attacks or sudden cardiac death.
To build the OCT registry, we are partnering with 20 prominent institutions internationally. Using information gathered from the registry, it is our goal to provide knowledge that will help doctors prevent heart attacks and sudden cardiac death. We are also evaluating the possibility of using OCT to prevent late catastrophic complications of stenting.
Why OCT Imaging
By creating extremely high-resolution images from within the artery, OCT can pinpoint the microscopic characteristics of a vulnerable plaque, as opposed to intravascular ultrasound (IVUS), which is more widely used, but has a lower resolution. Currently OCT is the only intravascular imaging technique with the resolution sufficient (approximately 10 µm) to delineate fine structures, such as thin fibrous caps and to characterize plaque types, such as lipid rich plaque. We have also discovered that OCT can detect subtle structural changes after PCI, such as plaque disruption including tissue prolapse and protrusion with high sensitivity.
Mass General Pioneers Using OCT Imaging
Researchers at Mass General are pioneers in the use of optical coherence tomography to view the coronary arteries at an unprecedented level. Over the past decade, we have led the way in using this technology by:

Researchers at Massachusetts General Hospital are leading the first optical coherence tomography (OCT) registry, with the goal of:
OCT imaging creates extremely high-resolution images from within the artery and can pinpoint the microscopic characteristics of a vulnerable plaque. To define these unique characteristics, we are creating a database with more than 3,000 patients who have had OCT imaging. We will then follow these patients for up to five years and collect detailed demographic and clinical information about them.
Using a prospective data collection approach, we will gather information for approximately 3,000 patients in our database. Our research team and international research partners will collect detailed demographic and clinical information for each patient for whom OCT is used using electronic case report forms (eCRF).
All patients in the registry will have had OCT imaging performed during cardiac catheterization.

We plan to follow all of the patients in our registry through phone calls or clinical visits six months after their OCT imaging, and then every year for up to five years. During this time, we will document any clinical events, which might include death, myocardial infarction, revascularization (target vessel and non-target vessel), ischemic cerebrovascular events and bleeding.
All patients’ identifiable information will be removed and a study code number will be assigned to each patient. This study number will be used in the eCRF and on the transferred images.
MGH Hotline 04.09.10 Optical coherence tomography (OCT) is an intravascular imaging technology that offers the promise of revealing the microscopic characteristics of a vulnerable coronary plaque.
OCT is a recently FDA-approved intravascular imaging modality, which is now available in many catheterization laboratories. However, most cardiologists are not familiar with this new technology. Cardiologists need more education about the interpretation of images and how to use the information to improve PCI and patient outcome.
