Minimally Invasive Cardiac Surgery: A Practical Overview for Clinicians

Minimally invasive cardiac surgery (MICS) has become an integral component of contemporary cardiovascular care, offering effective surgical treatment while reducing the physical and physiological burden associated with conventional median sternotomy. Through the use of smaller incisions, endoscopic visualization, and refined perioperative management, a broad spectrum of cardiac procedures can now be performed with safety and durability comparable to conventional approaches. These include coronary artery bypass grafting (CABG), mitral and aortic valve surgery, selected congenital heart defect repairs, and other intracardiac interventions. This review provides a practical overview of minimally invasive cardiac surgery for clinicians involved in the diagnosis, referral, and longitudinal management of patients with heart disease. Key topics include the range of procedures amenable to minimally invasive approaches, fundamental principles underlying their performance, and critical considerations for patient selection. The clinical benefits of MICS—such as reduced postoperative pain, faster recovery, shorter hospital stay, and improved quality of life—are discussed alongside important risks and limitations that may influence procedural choice. By emphasizing clinically relevant concepts rather than technical operative detail, this article aims to facilitate informed referral, shared decision-making, and effective multidisciplinary collaboration, supporting the appropriate integration of minimally invasive strategies into modern cardiac care.
