Since the completion of the first extracorporeal cardiac surgery in the middle of the last century, the field of cardiac surgery has been able to perform all kinds of surgeries from infants to the elderly, from complex precordial to acquired pathologies, from coronary bypass to large vessel surgery, from valve replacement to heart transplantation, and the surgical approach has become increasingly mature. However, most of the surgeries have been performed with a median incision in order to provide adequate exposure, which requires sawing through the sternum and causes greater trauma to the patient. Due to the destruction of the integrity of the sternum, postoperative patients often have more pronounced pain, and the whole recovery process is relatively long, and they still have hidden pain even when they encounter rainy and humid weather after a period of time. In recent decade, some minimally invasive procedures in cardiac surgery have been gradually carried out internationally, especially in the last few years, minimally invasive surgery has been accepted by more and more surgeons, and is also becoming more and more popular among patients. So what is minimally invasive? Minimally invasive is the use of smaller incisions to perform procedures that previously required greater trauma with less trauma. Minimally invasive surgery has been widely developed because of the reduction of trauma, which makes the whole treatment process significantly shorter and the patient’s recovery significantly better than before, so that both doctors and patients can get real benefits from it. Minimally invasive mitral valvuloplasty and replacement, minimally invasive aortic valve replacement, minimally invasive double valve replacement, minimally invasive atrial defect repair, minimally invasive ventricular defect repair, minimally invasive tricuspid valvuloplasty and replacement, minimally invasive thoracoscopic assisted surgery, robotic valve replacement surgery and robotic coronary artery bypass grafting have also been carried out in our hospital. The surgical incision has been shortened from a dozen centimeters to 4 or 5 centimeters or even 1 or 2 centimeters, and the hospital stay has been shortened from about two weeks to 4 or 5 days after surgery. The recovery period has been shortened, pain has been reduced, and the proportion and amount of blood transfusion has been significantly reduced, and the advantages of minimally invasive surgery have been fully realized. With the increasing maturity of the procedure and the improvement of the operating instruments, the concept of minimally invasive has been widely accepted by both doctors and patients. Cardiology catheter interventions are now in full swing, but there are still some shortcomings in catheter technology, and some diseases are not treated thoroughly enough, and minimally invasive cardiac surgery is a good complement to catheter technology. It can even be combined with the catheter technique, which is a new technique that is very popular internationally – hybrid surgery technique. Through these new techniques of minimally invasive surgery, the aim is to give patients the most excellent treatment and the least trauma, and it is believed that with the continuous development of medical science, these techniques will benefit a wider range of patients.
