Cardiac Catheterization Laboratory

The Cardiac Catheterization Laboratory (Cath Lab) in the Heart and Vascular Center provides the region's highest level of interventional cardiology diagnostic and treatment technologies. Experienced Dartmouth-Hitchcock (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.
