CathVision: A Smoother Look at Cardiac Electrograms
  CathVision is a Danish company that aims to reduce **isy electrogram*signals during Cardiac arrhythmia ablation procedures. With cleaner signals,*cardiologists can better locate the areas that generate arrhythmias and ablate them. For example, with a higher signal-to-**ise ratio, cardiologists can have higher confidence when probing the low-voltage areas of the heart. This is important because Cardiac arrhythmias, which affect 2% of the world, remain an untreatable challenge in about 50% of*ablation procedures. Patients with Cardiac arrhythmias have issues with conductance of the heart. In some cases, the wiring of the heart can short-circuit, causing circular conduction loops that fire and contract parts of the heart earlier than expected, throwing the entire heart out of rhythm. In other cases, aberrant tissue can*generate random, uncoordinated beats, which also throw the heart out of rhythm.*Either way, the condition can cause turbulent blood flow that then causes blood clots that get lodged in the brain, potentially causing stroke. Cardiac ablation is a treatment that*works by either destroying the short circuitry or the aberrant generation center to*restore **rmal heart conduction and beating. But for this to be effective, the doctors have to find the source of the problem. Often, they search for late potentials in scar-based arrhythmias, which are **t visible through the **ise of many existing systems. Also, mapping of atrial fibrillation is difficult due to the small signals generated from the atria. Cue CathVision. The CathVision Cube is a*20 x 20 x 20 cm signal processing box*that aims to*simplify*locating diseased tissue*and works with all diag**stic, mapping, and ablating catheters on the market today. It acts as a middle attachment that plugs into a procedure room’s existing medical equipment for rapid setup and use. It*translates*the signals from the catheters to*monitors in the room and can direct*RF signals for ablation when the diseased tissue has been found. Importantly, it reduces the **ise of the detection signal and*facilitates*interpretation of where diseased tissue is.  CathVision today an**unced receiving several*million dollars in venture capital funding from VF Ventures and Borean In**vation to prepare clinical testing in humans and prepare for regulatory approval. The company*has conducted two years of animal testing and currently expects to obtain*CE Mark in 2018.
