Advancements in Cardiac Surgeries: Minimally Invasive Cardiac Surgery Essay
Introduction
Minimally invasive cardiac surgery (MICS) is one of the recent innovations in cardiac surgery. It is characterized by small incisions as opposed to the traditional approach to cardiac surgeries which involved opening of the sternum or breastbone. MICS employs microsurgical approaches, video assisted and robotic surgeries to perform different procedures on the heart valves.
Minimally invasive cardiac surgery was introduced with the aim of achieving similar therapeutic effects as the traditional open-heart surgery but with a lesser degree of trauma to the patient as compared to the conventional approach.
Evolution of Minimally Invasive Cardiac Surgery
The traditional approaches to valve surgery and heart surgeries in general involved large incisions. However, advances in surgical instrumentation, video-assisted surgical techniques, anesthetic and perfusion procedures, and cardiac stabilizers have facilitated the introduction of minimally invasive surgeries.
The evolution of endoscopic imaging, robotic-assisted procedures, 3-D visualization, and cardiac stabilizers has led to the introduction of minimally invasive surgeries.
Types of Minimally Invasive Cardiac Surgery
1. Minimally Invasive Valve Surgery
Out of all the procedures that can be performed using minimally invasive cardiac surgery approaches, valve surgery has been the most common. Some of the procedures that fall under this category include minimally invasive mitral valve repair, minimally invasive mitral valve replacement, minimally invasive aortic valve procedures and tricuspid valve procedures. This approach can be used in either a small incision on the right side of the chest or a partial sternotomy. The advantage of using MICS in valve procedures is that it leads to reduced blood loss, less post-surgery pain, a few complications and faster recovery as compared to the traditional open-heart surgery. It also has an advantage in terms of cosmetic outcomes.
2. Robotic-assisted Cardiac Surgery
Robotic-assisted cardiac surgery, a type of robotic-assisted procedures, is a minimally invasive cardiac surgery procedure that allows for doing more elaborate surgeries. This is because the procedure offers a better visualization of the surgery site in three dimensions and provides a good deal of flexibility and precision. Robotic-assisted cardiac surgery is done by making small incisions in the chest. Some of the procedures that can be performed using this method include:
a) Mitral valve surgery
b) Atrial Septal defect repair
c) Coronary artery bypass grafting
3. Minimally Invasive Coronary Artery Bypass Surgery
Minimally Invasive Coronary Artery Bypass Surgery is a procedure that bypasses one or more narrowed coronary arteries that supply blood to the heart. It is a minimally invasive approach to the traditional coronary artery bypass grafting (CABG). The traditional CABG procedure involved making very large incisions in the breastbone to open the heart but MICS can be used.
Some of the techniques that may be used in MICS include MIDCAB – minimally invasive direct coronary artery bypass and TECAB – totally endoscopic coronary artery bypass. These techniques differ from the traditional CABG in that smaller incisions are made in the chest. The MICS procedures for coronary artery bypass graft have several advantages over the traditional approach. They lead to less trauma to the patient and hence reduced length of hospitalization and quick recovery. The procedures have also been associated with reduced post-surgery pain and reduced risks of infections.
4. Hybrid Coronary Revascularization
Hybrid coronary revascularization is a minimally invasive procedure that involves the combination of bypass grafting and percutaneous intervention to revascularize the coronary artery. This procedure utilizes surgical and catheter-based techniques to treat complex forms of coronary artery diseases including those affecting the left main coronary artery.
Technologies used in Minimally Invasive Cardiac Surgery
1. Advanced Imaging
With the current advanced technologies that have been introduced into cardiac surgery, it is now possible to perform various procedures with a high degree of precision. This is evident in the adoption of 3-D echocardiography and cardiac computed tomography imaging to visualize the heart in intricate detail. Transesophageal intraoperative imaging has also been useful in some procedures.
2. Robotic-assisted Surgery
This is one of the technologies that have been adopted in minimally invasive cardiac surgery. Robotic-assisted procedures have been a great advantage to cardiac surgeons because they facilitate the performance of various procedures.
3. Specialized Surgical Instruments
There is also a great advantage associated with the use of various specialized surgical instruments in minimally invasive cardiac surgery.
Benefits of Minimally Invasive Cardiac Surgery
Compared to the traditional open-heart surgery, minimally invasive cardiac surgery has several benefits. The benefits associated with minimally invasive cardiac surgery include:
1. Smaller incisions
2. Less blood loss compared to traditional open-heart surgery resulting in reduced need for blood transfusion
3. Less risks of infection
4. Less post-surgery pain
5. Shorter length of hospitalization
6. Faster recovery
7. Earlier return to work and resumption of other activities
8. Overall high level of patient satisfaction
Limitations and Challenges of Minimally Invasive Cardiac Surgery
1. The minimally invasive approaches are not always available
2. It may take a long time for a surgeon to acquire the skills and experience to perform minimally invasive procedures. Robotic-assisted procedures also require skills on the part of the surgeon.
3. In addition, minimally invasive procedures require resources such as equipment and skills.
4. The procedures also present technical challenges.
5. Close post-surgery monitoring is also required.
The choice of procedures should be patient-centered.
Future of Minimally Invasive Cardiac Surgery
The future of minimally invasive cardiac surgery is very bright since it has the potential to overcome many of the limitations of the traditional open-heart surgery. In the future, minimally invasive procedures will be used to perform most of the procedures that are currently done using the traditional approaches. Some of the innovations that will be useful in the future include robotic-assisted procedures, artificial intelligence and advanced imaging technology, specialized instruments and totally endoscopic approaches. It is also likely that there will be a hybrid approach to some of the procedures using minimally invasive approaches and traditional cardiac catheterization.
Conclusion
Minimally invasive cardiac surgery has revolutionized cardiac surgery and enabled the performance of various procedures with less trauma to the patient. It is very likely that the future of minimally invasive cardiac surgery will involve the adoption of more advanced technology in cardiac procedures.
