TARGET
When the heart is the target
Cardiac radioablation puts an ablative dose into the heart itself. The target moves with every beat and every breath. Everything around it is tissue you want to keep.
01 / Why it matters
Every millimetre of margin is healthier heart
Millions live with arrhythmias that drugs and catheters fail to stop. Radiation can reach the substrate from outside the body. Motion is what stands in the way.

CardioKit radioablation What we aim for**
20–80%Acute success, idiopathic to scar-related VT*
~90%Success we expect from a gated session**
2–7 hInvasive procedure, up to 10 staff*
~2 hNon-invasive, beam from outside the body†

or flutter alone), 2019 HRS/EHRA consensus (20–80 %, idiopathic to

Congruence Market Insights (2025).
~5.5 M, 90,000 procedures a year, 2–7 h and staff counts are EBAMed estimates.

~90 % and ~2 h are the targets EBAMed designs CardioKit
against, not clinical results.
02 / Dual gating
Two rhythms, one gating window
Respiratory gating is routine using surrogates.Cardio-respiratory gating is not, because nothing in the treatment room sees the heart in real-time.
Primary focus today
INDICATION 01
Ventricular tachycardia
Scar-related VT after failed catheter ablation. The first indication, with the largest published record, and the one CardioKit is being built and trialled for.
What we aim for next
INDICATION 02
Primary cardiac sarcoma
A malignant tumor of the heart wall. Rarely resectable in full. Moves with the muscle it grows from.
INDICATION 03
Septal reduction in HOCM
Thinning the septum that blocks outflow in hypertrophic cardiomyopathy. No surgery, no catheter.
03 / Ventricular tachycardia
An electrical circuit trapped in scar.
Stereotactic arrhythmia radioablation, STAR. One dose of radiation switches off a rhythm disorder.
Deliver one dose to the scar driving the arrhythmia. The same tissue a catheter would burn, reached from outside the body. Protons stop at a chosen depth and deliver the dose on the target.
In weeks, conduction through the scar is disrupted. In months, fibrosis breaks the circuit for good. One session, outpatient. No anesthesia, no catheter.
