Dr. Walk has special interests in cardiac surgery, arrhythmia surgery, heart failure, mechanical circulatory support, and extracorporeal membrane oxygenation (ECMO). He treats a wide range of cardiovascular conditions, including coronary artery disease, heart failure, atrial fibrillation (A-Fib), valvular heart disease, cardiogenic shock, and aortic disease.

Dr. Walk's approach to patient care is rooted in collaboration. He works closely with multidisciplinary care teams, patients, and their families to ensure they understand their condition and available treatment options. Together, they develop a personalized plan focused on achieving the safest and most effective outcome. Guided by the philosophy, “Do the most good,” Dr. Walk considers it both a privilege and a responsibility to care for patients during some of the most critical moments of their lives.

His interest in cardiac surgery developed during his general surgery residency, where he was drawn to the opportunity to make a meaningful impact on patients facing serious heart conditions. He finds the greatest reward in seeing patients recover from major heart surgery, return to their families, and regain the ability to enjoy their daily lives.
