HeartFlow coronary CT assessment
NHS Western Isles reported avoiding unnecessary invasive procedures with HeartFlow coronary assessment
Problem
Patients needing invasive coronary investigations faced long journeys to mainland services. The Western Isles lacked resident cardiology consultants and permanent radiologists.
Approach
NHS Western Isles began a HeartFlow pilot in December 2020 and moved to routine use in 2021. The service used coronary CT images for non-invasive blood-flow assessment to inform referral decisions.
Results
No published figures
Takeaway
The board reported fewer unnecessary invasive investigations and associated mainland journeys. It did not publish a local effect size in the assessment.
