HeartFlow added another $65 million to its coffers for the heart function analysis it developed.

Redwood City, Calif.-based HeartFlow, which developed the FFRct fractional flow reserve analysis, said it hopes to raise another $35 million in the equity round. Nine unnamed investors participated, with the first sale occurring June 11,HeartFlow said in a regulatory filing.

FFRct works by taking the data from a standard CT scan and applying algorithms that result in a color-coded 3D “map” detailing changes in flow across coronary lesions.

Last month, the company named former Beaver-Visitec chief Dana Mead Jr. as its new president & CEO, replacing Dr. John Stevens, who stayed on as chairman. HeartFlow closed a $240 million Series E round in February 2018.
