Expert cardiology, cardiothoracic and vascular care
Your heart’s in good hands.
Northbay Health Heart and Vascular is the only comprehensive location for advanced cardiovascular services in Solano County. Equipped with the latest technology and evidence-based care, our cardiologists specialize in diagnosing and treating diseases of the heart and blood vessels. Our comprehensive cardiology services and specialty heart care includes the region’s first accredited Chest Pain (Heart Attack) Center, the only cardiothoracic surgery program in Solano County and our Heart Failure Clinic.
Our expert teams include interventional cardiologists, cardiac electrophysiologists, cardiothoracic surgeons, vascular surgeons and highly specialized cardiac nurses and technologists. We perform many cardiac procedures using non-surgical interventional techniques and minimally invasive surgery, which can mean less pain, smaller incisions and a faster, easier recovery for patients.
