Unsung Heroes of Coronary Interventions: Indian Cardiac Surgeons and the Challenges of South Asian Coronary Anatomy and Physiology

Background and significance: The coronary artery disease (CAD) epidemic has seen a logarithmic increase in morbidity and mortality over the past decade. Cardiovascular diseases account for about 19.1 million deaths annually—with 80% of reports coming from low and middle-income countries, which have been attributed to a lack of infrastructure, human resources, and financial coverage. In tandem with the developed world, India has also seen significant growth in interventional and surgical cardiovascular care. The dominance of coronary artery bypass grafting (CABG) procedures in India has attracted the attention of the world. With this review, the authors aim to highlight the role of cardiac surgeons in India as the “unsung heroes” of coronary interventions. Observations: A pernicious atherosclerotic pathology develops in thendian population as a result of genetic and socio-cultural predispositions, which is further complicated by anatomical and physiological differences. The pathology manifests as a diffuse disease in relatively small caliber coronary arteries, necessitating the consideration of CABG over interventional procedures. Indian cardiac surgeons have stood up to the challenge and have powered health tourism to India from around the world due to the excellent success rate and long-term outcomes at a 50–80% lesser cost than most developed countries. Beyond the costs, a major highlight is the high rate of arterial bypass and off-pump surgery. These balance the unbridled exuberance of the interventional cardiology medical–industrial complex, providing a critical balance that benefits patients and improves acute and long-term outcomes. Conclusions: Indian cardiac surgery is now known globally not only for its affordability but also for the skill set and the quality of surgeons. The surgeons’ vast experience and risk-taking capacity have made them an indispensable part of the interventional cardiology team and has allowed a multidisciplinary collaboration that inspires the world. This is evident from the rising trend of medical tourism to India.
