Low-Cost Innovations in Global Cardiac Surgery.

Cardiovascular diseases are the leading cause of morbidity and mortality worldwide, costing the lives of 18 million people annually, with up to one-third being attributable to cardiac surgical conditions. Approximately 6 billion people do not have access to safe, timely, and affordable cardiac surgery, predominantly affecting populations living in low-middle income countries. Cardiac surgical care is costly, resulting in few centers in variable-resource contexts operating continuously or with the resources observed in higher-resource environments.
