Image-guided interventions may be difficult for patients to conceptualise resulting in incomplete understanding of peripheral angiography and angioplasty before consent to the procedure. Time constraints, language barriers, and lack of physical IR clinic during COVID pandemic present additional obstacles. We developed and introduced digital animations to support consent and assessed the effect on patient understanding.

Material(s) and Method(s):

Multi-language animations (English, Welsh, and Arabic) explaining angiography and angioplasty (www.explainmyprocedure.com/irdemo), developed with patient and clinician involvement. These were introduced in a university hospital and shown to patients pre-procedure. Reported understanding of the reason for the procedure, its benefits, risks, and alternative treatments was assessed in 20 consecutive patients before introduction of the animations into practice (no animation group) and in 12 consecutive patients after their introduction (animation group). Patient understanding in the two groups was compared.


The proportions of patients who completely understood the procedure and its benefits, risks, and alternatives were 55%, 65%, 15% and 10% respectively in the “no animation” group, and 83%, 83%, 67% and 67% in the “animation” group (p= 0.1, 0.2, <0.5, and <0.5 respectively for each comparison).


Use of multi-language animations explaining angiography and angioplasty is feasible, was associated with improvement in patient understanding before the procedure, and assisted in overcoming obstacles imposed by the current COVID pandemic.
