Heart surgery is a treatment for heart disease that helps reduce severity and return the heart to normal function, with continuous development of surgical techniques. One of them is Minimally Invasive Cardiac Surgery (MICS), where the heart is operated on without making an incision in the middle chest bone (Non – Median Sternotomy), and the surgical wound is smaller, resulting in less pain, faster recovery, reduced complications, and lower mortality rates.
What is Minimally Invasive Cardiac Surgery (MICS)?
Minimally Invasive Cardiac Surgery (MICS) is a technique used in heart surgery without the need to cut through the chest bone as in traditional methods. It is performed by a specialized medical team using special equipment for minimally invasive cardiac surgery. The cardiac and thoracic surgeon makes a small incision on the side of the chest, under the breast or between the ribs, instead of a large middle chest incision of 15 – 30 centimeters. This results in less pain for the patient, less blood loss, and a smaller surgical wound of about 3 – 5 centimeters, reducing damage to tissues and internal organs, and lowering the risk of postoperative infection. Patients experience less pain than with traditional surgeries that require cutting through the middle chest bone, recover faster, spend less time in the hospital, and return to a quality life more quickly.
What heart conditions can Minimally Invasive Cardiac Surgery (MICS) treat?
- Coronary artery disease
- Heart valve stenosis or regurgitation
- Arrhythmia
- Congenital heart defects such as Atrial Septal Defect (ASD)
- Heart tumors
Minimally Invasive Cardiac Surgery Techniques
There are various techniques of minimally invasive cardiac surgery depending on the type of heart disease. For example:
- Minimally Invasive Cardiac Surgery Coronary Artery Bypass Grafting (MICS CABG) is a new option for treating coronary artery disease by using special equipment to make a small incision at the ribs or under the left breast, about 7 – 10 centimeters, instead of the traditional chest bone incision, to bypass narrowed or blocked coronary arteries to restore blood flow.

- Totally 3D Endoscopic Valve Surgery is an advanced technique for patients with valve regurgitation or stenosis, especially those with contraindications for traditional open-heart surgery, such as the elderly or those with complex comorbidities. This approach uses a high-resolution small camera with a 3D visualization system for valve repair and replacement through small incisions without opening the chest bone. Click here

Who is Minimally Invasive Cardiac Surgery (MICS) suitable for?
- Patients with medical indications
- Patients who do not want to undergo chest bone incision surgery
- Older patients who want to reduce the risk of major surgery
- Patients with valve regurgitation or specific heart conditions that can be accessed via small incisions
- Patients without complex comorbidities who can undergo minimally invasive cardiac surgery, such as severe chest deformities or chronic obstructive pulmonary disease
Patients with heart disease who wish to undergo Minimally Invasive Cardiac Surgery (MICS) must be evaluated by a specialized thoracic surgeon in minimally invasive cardiac surgery.
