About

Ettore Lanzarone is a leading researcher in cardiac surgery, with a focused expertise in robotic-assisted mitral valve repair and the economic evaluation of minimally invasive surgical techniques. His work critically examines the learning curve associated with robotic procedures, notably incorporating the disruptive impact of the COVID-19 pandemic as an exogenous factor in surgical training and outcomes. A key contribution is his comparative analysis of robotic versus minimally invasive mitral valve surgery, where he investigates whether the higher upfront costs of robotic systems are offset by superior clinical benefits and reduced hospital stays. His most cited paper (9 citations) provides a single-center analysis of the learning curve for robotic mitral valve repair during the pandemic, offering essential data for surgical program planning. In a subsequent study (2 citations), he directly compared the cost-effectiveness of robotic and minimally invasive approaches, addressing a critical question in healthcare resource allocation. Lanzarone’s research is vital for surgeons and hospital administrators seeking to balance technological advancement, patient outcomes, and economic sustainability in modern cardiac care.
