Cardiac surgery represents one of the most advanced integrations of physiology, biomechanics, uid dynamics, thermodynamics, and bioengineering in modern medicine. Despite remarkable progress in cardiopulmonary bypass, myocardial protection, coronary revascularization, valve reconstruction, transplantation, extracorporeal membrane oxygenation (ECMO), ventricular assist devices (VADs), and robotic surgery, the discipline remains procedurally compartmentalized without a universal theoretical framework integrating its physiological and physical principles. This article proposes that the entirety of cardiac surgery can be fundamentally reduced to three governing laws: The Law of Flow, the Law of Structure, and the Law of Protection. The Law of Flow defines preservation of myocardial and systemic perfusion as the primary determinant of survival and models cardiovascular circulation through conservation equations, Poiseuille dynamics, oxygen transport kinetics, and Navier–Stokes fluid mechanics. The Law of Structure establishes that physiological geometry governs biomechanical effciency and incorporates Laplace wall stress relationships, Reynolds turbulence analysis, pressure-volume energetics, and finite element modelling. The Law of Protection recognizes that surgical intervention itself produces thermodynamic instability, inflammatory activation, and ischemia-reperfusion injury, which may be mathematically analysed through entropy generation, heat transfer equations, and shear-stress-mediated hemocompatibility models. Together, these laws provide a unified systems-based doctrine capable of integrating coronary surgery, valve repair, congenital reconstruction, mechanical circulatory support, transcatheter therapies, robotics, artificial intelligence-assisted perfusion, and computational cardiovascular engineering. The framework redefines cardiac surgery as an applied discipline of biological physics and dynamic systems optimization operating under conditions of temporary physiological suspension.
