Cardiac surgery has evolved into a highly sophisticated discipline integrating physiology, biomechanics, molecular biology, perfusion science, and bioengineering. Despite major advances in coronary revascularization, valve reconstruction, transplantation, mechanical circulatory support, extracorporeal circulation, minimally invasive techniques,and robotic-assisted surgery,the specialty lacks a unified theoretical framework capable of synthesizing its diverse operative principles into a single physiological doctrine. This article proposes that the entirety of cardiac surgery may be fundamentally understood through three governing laws:the Law of Flow,the Law of Structure, and the Law of Protection. The Law of Flow establishes that preservation of myocardial and systemic perfusion is the primary determinant of cellular survival and operative success. The Law of Structure emphasizes that physiological geometry governs biomechanical efficiency and long-term cardiovascular performance. The Law of Protection recognizes that surgical intervention itself initiates inflammatory, ischemic, and reperfusion-mediated injury, requiring advanced strategies for biological preservation.Together,these principles integrate the scientific foundations of coronary artery bypass grafting, valve repair, ventricular reconstruction, congenital surgery, extracorporeal membrane oxygenation, ventricular assist devices, robotic surgery, and transcatheter therapies into a single systems-based framework. Historically, cardiac surgery evolved first through mastery of perfusion, then through restoration of geometry, and increasingly through minimization of biological injury.The proposed framework provides a conceptual foundation for future advances in precision perfusion,computational hemodynamics,biomaterials engineering,artificial intelligenceguided surgery, and next-generation myocardial preservation technologies.These three laws may therefore serve as a unifying physiological paradigm for modern cardiovascular intervention.
