Replacement of an end-of-life cardiac catheterization laboratory ("cath lab") can pose a significant challenge to a hospital, particularly in single-cath-lab institutions. The disruption in patient care requires innovative approaches to minimize the inconvenience and ensure ongoing quality of care. We describe a unique approach whereby Michael Garron Hospital (MGH) "leased" a cath lab within Sunnybrook Health Sciences Centre for a 12-week period during a cath lab replacement project at MGH. The MGH cath lab and patient recovery bay remained a completely separate entity staffed by MGH nurses and physicians, with electronic connection to the home hospital. A total of 420 patients underwent cardiac catheterization with no adverse outcomes while maintaining system efficiency and high patient and staff satisfaction. Cath lab leasing involving two cooperating hospitals is an innovative and safe way to bridge a cath lab replacement.
