The CathWorks angiography image derived FFR assessment system has received national reimbursement approval in Japan. The system uses a rotational angiography image dataset taken while the patient is in the cath lab to quickly reconstruct a 3-D coronary tree showing FFR numbers for all of the artery segments.

In the past decade there has been a proliferation of clinical-grade wearable monitors and implantable devices such as pacemakers, ICDs, implantable cardiac monitors, and new pacemaker-like devices that can control hypertension. In the near future, these devices will be tied into a body-wide internet of things for specific patients that can transmit patient data to clinicians wirelessly to enable an integrated, more robust form of telecardiology and telemedicine.
