When complex becomes simple...

Our approach.

We endeavor to providing accurate AI-based algorithms to cardiac electrophysiologists. Our first product, VX1, is designed to outperform human experts in intracardiac multipolar signal analysis. VX1 delivers AI-based knowledge to operators while they intervene on patients.

About Interventional Electrophysiology

Interventional electrophysiology is a surgical specialty that requires multiple years of experience. It consists of conducting intra-cardiac procedures designed to cure cardiac arrhythmias. During a procedure, an ablationist is required to comprehend a large amount of information. On the one hand, visual analysis of multiple -up to 30- electrograms displayed in real-time is essential. On the other, a large amount of non-electrogram information coming from multiple sources has to be taken into account. This heterogeneous flow of data has to be interpreted in real time so as to progress through the multiple-step workflow of any given procedure.

About Atrial Fibrillation

The heart beats due to electrical impulses coming from the sino-atrial node, a small tissue in the right atrium. This causes both upper chambers of the heart – the two atria- to contract and move the blood to the lower chambers of the heart – the ventricles.

AF is the most common heart rhythm disturbance in adults (a.k.a atrial arrhythmia). ).The heart beating of AF patients in is fast and irregular, and blood doesn’t flow properly within the heart. This activity, caused by a sudden abnormal electrical impulse in the atria, may be recorded by an electrocardiogram (ECG) and therefore diagnosed. AF sub-types are defined by duration of arrhythmia episodes. AF may occur in brief episodes, a.k.a paroxysmal AF, in longer episodes, a.k.a persistent AF, or as a more permanent condition where the atrial fibrillation is present all the time, a.K.a. permanent AF.

The symptoms of AF differ individually. They include:

  • Tiredness or lack of energy
  • Abnormal pulse
  • Shortness of breath
  • Heart palpitations
  • Dizziness, lightheadness or fainting
  • Pain or discomfort in your chest

AF can damage and weaken the heart over time through electrical “remodeling” that occurs in response to both functional— i.e. altered electrical activation— and structural— i.e. heart failure, myocardial fibrosis, etc. Functionating and size of the heart are severely altered by AF. In fact, the “shivering” of the heart’s upper chambers increases the risk of developing a blood clot formation and stroke.

33.5 million individuals worldwide are affected by AF1. In Europe, approximately 11 million individuals have AF and this number is estimated to grow to 14-17 million by 2030, with 120 000 to 215 000 new cases expected every single year2,3. Evidence suggest a greater AF prevalence in patients with conditions such as hypertension, heart failure, coronary artery disease, obesity, diabetes.

Recent studies show that 20–30% of patients with an ischemic stroke have had AF before, during, or after the initial event. AF indeed increases the probability of stroke in four to five times. Furthermore, AF-induced strokes are associated with more severe outcomes. For example, AF-related strokes cause brain white matter lesions, cognitive impairment, decreased quality of life and depressed mood as well as an astonishing hospitalization rate of 10–40% annually4.
