a. Mitral Valve Repair and Replacement: The mitral valve is one of the four valves in the heart, and it controls blood flow between the two chambers on the left side (the left atrium and the left ventricle). Sometimes, this valve may not close properly, leading to blood leaking backward—a condition called Mitral regurgitation—or it may become stiff and narrow a condition called Mitral stenosis , which restricts blood flow. Mitral valve repair and replacement are procedures that fix these issues:
- Repair involves techniques to fix the patient’s existing valve. This can include reshaping the valve, reinforcing it with a ring, or fixing the supportive tissues around it.
- Replacement involves removing the damaged valve and replacing it with an artificial valve made of metal or animal tissue.
With minimally invasive techniques, these surgeries are done through small cuts in the chest rather than the large incision of traditional open-heart surgery. This allows faster recovery, less pain, and a shorter hospital stay.

b. Aortic Valve Replacement
The aortic valve controls blood flow from the heart to the rest of the body. When this valve is damaged, it can lead to aortic stenosis (a narrowed valve that restricts blood flow) or aortic regurgitation (a valve that doesn’t close fully, causing blood to leak back into the heart).
In aortic valve replacement:
- The damaged aortic valve is removed and replaced with a new valve. This replacement valve may be made from materials like metal or tissue from animals.
- Small incisions are used to access the heart, and advanced tools and imaging help guide the surgeon for precise valve placement.
By using minimally invasive techniques, recovery times are shorter, and the patient can resume normal activities sooner.
c. Tricuspid Valve Procedures
The tricuspid valve regulates blood flow between the right atrium and the right ventricle, the chambers on the right side of the heart. When this valve is damaged, it can lead to problems like tricuspid regurgitation (leakage of blood backward) or tricuspid stenosis (narrowing of the valve).
Tricuspid valve repair and replacement can be done using minimally invasive techniques:
- Repair involves tightening or reshaping the valve or reinforcing it to close more tightly and prevent leaks.
- Replacement is considered if repair isn’t possible. The damaged valve is removed, and a new valve is placed to restore proper blood flow.
These procedures are done with small incisions and special tools that limit damage to surrounding tissue, making recovery quicker and less painful.

d. Multiple Valve Surgeries
Some patients may have problems with more than one heart valve, such as both the mitral and aortic valves. When two or more valves are damaged, it can affect the heart’s ability to pump blood efficiently.
Multiple valve surgeries allow doctors to repair or replace multiple valves in a single procedure, which can restore normal blood flow and improve heart function. With minimally invasive techniques, surgeons make small cuts in the chest rather than a large incision, reducing recovery time and lessening pain. This approach allows patients to heal faster while still receiving comprehensive treatment for multiple valve issues.
e. Valve-Sparing Aortic Root Procedures
The aortic root is the part of the aorta closest to the heart, where the aortic valve and coronary arteries are attached. When this area is damaged or weakened, such as by an aneurysm (a bulging, weakened area in the artery), it often needs repair to prevent serious complications. In valve-sparing aortic root procedures, surgeons repair the aortic root without removing the natural aortic valve. This approach preserves the patient’s original valve, which often works better than an artificial replacement and reduces the need for blood-thinning medications.Using small incisions and specialized tools, this minimally invasive technique allows for quicker healing and a faster return to normal activities for patients who are suitable candidates.
