Name: John Martin
New title: Chief medical officer, Cardiosense
Previous title: Chief medical officer emeritus, Butterfly Network
Cardiosense has appointed John Martin as chief medical officer. The appointment puts Martin in charge of clinical development and product strategy as the company prepares for commercial launch.
Chicago-based Cardiosense recently received Food and Drug Administration clearance for its wearable heart monitor, CardioTag. The company is developing AI models that use data captured by the monitor, for example to estimate pulmonary capillary wedge pressure in heart failure patients. Cardiosense is now working to validate its cardiac filling pressure algorithm and prepare a regulatory filing for the AI tool.
Amit Gupta, Cardiosense co-founder and CEO, said in a statement that Martin’s combination of clinical expertise and medtech leadership will benefit the company as it tries to bring the algorithm to market.
Martin, a practicing vascular surgeon, joins Cardiosense from point-of-care ultrasound company Butterfly Network. Butterfly works across medical specialties but cardiology is a focus area. At Butterfly, Martin was involved in work including a collaboration with the American College of Cardiology and research into the use of machine learning and handheld ultrasound devices to screen for aortic stenosis.
At Cardiosense, Martin will build on initiatives such as a clinical trial that found CardioTag and an AI algorithm can estimate PCWP with an accuracy approaching that of implantable hemodynamic sensors. The company is focusing on PCWP in the belief the metric can provide an early indication of the deterioration of heart failure patients.
If authorized by the FDA, the algorithm paired with CardioTag could offer an alternative to Abbott’s Cardiomems implant. Cardiomems monitors another sign of worsening heart failure. Cardiosense has identified procedural risk, patient burden and low penetration among eligible heart failure populations as limitations of implantable monitors that it is aiming to overcome with its products.
