Advances in Modern Cardiac Surgery Essay

The field of cardiac surgery has witnessed tremendous progress over the years due to the combined effort of enhanced diagnostic imaging, minimally invasive surgeries, artificial intelligence and robotics, mechanical circulatory support, and regenerative medicine. There is a wide variety of surgeries that is less invasive, highly efficient, and appropriate for the treatment of cardiovascular diseases.

The modern treatment of cardiac diseases is characterized by minimally invasive surgeries that provide an opportunity to use various therapeutic strategies. For example, a minimally invasive approach that includes making a small incision is currently available for valve repair surgeries. Such surgeries as video-assisted and robotic surgery also allow for minimally invasive approaches to be used. As a result, there is reduced trauma to the chest, reduced hospitalization, rapid recovery, and reduced post-surgery discomfort.

A large number of cardiovascular interventional procedures that previously required open-chested surgery can now be accomplished using less invasive catheterization methods. The most common transcatheter procedure is aortic valve replacement that is indicated for aortic valve stenosis. The replacement of the aortic valve is performed with a special catheter, which is inserted through the femoral artery. Other transcatheter procedures include the treatment of the mitral valve, which is indicated for a variety of mitral valve diseases. Another example is the minimally invasive treatment of secundum atrial septal defect and patent foramen ovale.

3. Robotic-assisted Surgery

Robotic-assisted surgery provides the opportunity to perform surgeries with a higher accuracy level. This method is indicated for numerous procedures, including mitral valve repair, coronary artery bypass grafting, and tumor removal. The robotic-assisted cardiac surgery is characterized by several small incisions in the patient’s chest, through which a special surgical instrument and a miniature camera are inserted.

The current state of coronary artery bypass grafting surgery (CABG) is largely dominated by innovations that include new graft materials, minimally invasive surgery, and the use of alternative percutaneous approaches. These technologies have significantly reduced post-surgery discomfort and improved the overall recovery process. One of the major advancements in CABG is the possibility to perform the procedure without the use of a heart-lung machine. Arterial grafts, including internal mammary arteries, have also become more preferred than venous grafts. Another major advancement is hybrid revascularization that combines minimally invasive direct coronary bypass grafting and percutaneous coronary interventions.

The current state of the surgery of the heart valves is largely focused on the variety of options available in valve repair and replacement. The repair of heart valves allows for reducing the workload of the heart and avoiding the need for complete replacement of the valves with prostheses in many cases. At the same time, there is a large choice of both mechanical and biological valves. In addition, there is now an opportunity to consider the individual characteristics of each patient with a heart valve disease.

A large variety of innovative imaging technologies is now available to plan and perform the cardiac surgery. The most common include three-dimensional echocardiography, cardiac computed tomography (CT), and magnetic resonance imaging (MRI). These methods allow for obtaining a detailed assessment of the heart structure to determine the most appropriate treatment strategy. Three-dimensional printing allows for creating heart replicas based on which the personal strategy of the operation is developed, and the surgeon trains.

The use of artificial intelligence in cardiac surgery has allowed for planning the most appropriate treatment and predicting post-surgery risks and complications. The technologies of artificial intelligence are also used to assist a doctor and ensure the high accuracy of the procedure, including the analysis of the image of the heart. Digital technologies also contribute to the determination of the individual characteristics of each patient.

The technology of mechanical circulatory support helps to maintain a patient’s circulation throughout the recovery period. This method allows for supporting the function of the heart and is indicated for patients with severe forms of cardiovascular diseases. In particular, ventricular assist devices (VADs) are used to help maintain blood flow in patients whose hearts are not able to pump blood sufficiently. In addition, there are total artificial hearts, which can be used as a temporary measure to support the patient. Extracorporeal membrane oxygenation (ECMO) is another method of temporary life support for patients whose hearts or lungs are unable to function properly.

The improved outcomes of heart transplantation are associated with the opportunity to use new technologies for donor screening as well as immunosuppressive protocols. The introduction of new standard perfusion machines and improved donor heart preservation techniques also extended transplant survival. At the same time, there is now an opportunity to consider the use of a heart from an extended donor pool.

Regenerative medicine and tissue engineering are promising areas that allow for repairing heart tissue and treating cardiovascular diseases. In particular, stem cell therapy, gene therapy, and tissue engineering technologies are being developed, which allows for repairing heart cells after injury and myocardial infarction. In addition, these methods make it possible to restore the function of the heart after cardiomyopathy and significantly improve the patient’s quality of life.

The concept of enhanced recovery after cardiac surgery (ERACS) aims to optimize post-surgery care, reduce post-operative discomfort, and improve the quality of life of the patient. A few days of hospitalization after surgery and the use of special anesthetic analgesics during the procedure help to reduce stress and allow for a faster return to normal life after surgery.

Cardiac surgery will continue to develop and improve in the future as a result of the combined efforts of surgeons, researchers, and engineers. Less invasive and non-invasive surgeries, including minimally invasive procedures and interventional catheterization techniques, will continue to be developed. In addition, robotic-assisted surgeries and artificial intelligence will be used more often in cardiac surgery. Digital technologies will also be useful in developing an individualized approach to each patient. Finally, the concept of enhanced recovery is also important because it is beneficial for both patients and hospitals. Moreover, it is also critical to develop new methods of regenerating tissues and cells, as well as technologies for artificial organs. All of these measures will improve the treatment of cardiovascular diseases and increase the quality of life of patients.
