Technology holds a significant role in the past, present, and future of cardiac surgical care capacity in low-to-middle income countries (LMICs): a role that holds positive value overall in opportunity and outcome, despite recurrent and emerging practical and ethical challenges to different stakeholder groups. Aided by case studies, this chapter discusses the value of both creating technologies to benefit cardiac surgical care directly, and creating environments for technological innovation. This is addressed by examining the value of technology for, and within, human and physical resource development. Human resource development, consisting of cognitive, technical, and reflective components, is developed through two complementary approaches: increasing the minimum quality standard achieved by healthcare professionals, and increasing the maximum quality standard achievable. Both of these strategies are hugely helped by the implementation of technology to facilitate new training methods, relationships, and career opportunities. The discussion of physical resource development is guided by the journey of development and implementation taken by individual technologies, identifying key forms of support required to combat potential issues and increase the chance of success. Technology requires significant resource investment by a varied portfolio of stakeholder groups to deliver on its current achievable, and future potential promise to contribute significantly towards cardiac surgical capacity development in LMICs.
