# Elucid Raises $55M Series D for AI Cardiovascular Diagnostics Platform

> Elucid, a Boston company building AI software to read cardiovascular imaging, has closed an oversubscribed $55M Series D, lifting its total funding to roughly $185M. The round adds a large medtech company as its fourth publicly traded strategic investor, a signal that established players want a stake in AI-driven heart diagnostics. The pitch is to replace or reduce invasive procedures. Elucid's BioIntegrated FFR-CT, now under FDA 510(k) review, aims to measure blood flow blockages from a CT scan with accuracy rivaling invasive FFR, while its already-cleared Plaque-IQ analyzes arterial plaque. Together the company presents them as a single decision-support platform for cardiologists. Cardiovascular disease remains the leading cause of death worldwide, so tools that catch dangerous plaque earlier and less invasively have obvious appeal. The money here funds commercial expansion and clinical studies, which is the real test: regulatory clearance and hard outcome data, not just an accurate model, are what determine whether this reaches patients.
