Cardiac Catheterization Laboratory
The Cardiac Catheterization Laboratory in the Heart & Vascular Center provides the region's highest level of interventional cardiology diagnostic and treatment technologies. Experienced D-H specialists perform the full range of procedures, from low-risk to extremely high-risk coronary and structural heart interventions, some of which are only be available through clinical trials.
The laboratory is staffed 24 hours a day, 365 days a year, and provides scheduled procedures as well as emergency and urgent procedures. The DHART (Dartmouth-Hitchcock Advanced Response Team) transports you from regional community hospitals to the D-H Cath Lab.
