“Closed” Method Aortic Aneurysm Endovascular Stent Treatment: “EVAR” and "TEVAR"
Endovascular Aortic Surgery is one of the best inventions in Cardiovascular Surgery during recent years. It reduced surgery risks and hospital stay considerably. Before the 2000s, Aortic Surgery was the most severe operation with the highest risk of complications. As technology is developing day by day, now, Aortic Surgeries can be performed with the closed method, easily.
Aortic Valve Surgery
A healthy heart contracts 70-80 times in a minute and approximately 100.000 times in a day. In this way, 300 lt. of blood is pumped to the whole body in an hour. In a normal heart, there are 4 cavities. 2 upper cavities are called right and left atriums, lower cavities on the other hand are called left and right ventricles. Heart’s duty is to transfer oxygenic blood to whole body.
What is Mitral Valve Surgery? Is it dangerous?
Valves situate between cardiac chambers or between cardiac chambers and main veins and they regulate blood flow according to heart’s pumping characteristic. There are 4 valves in the heart. Aortic and mitral valves are on the left side and they pump oxygenic arterial blood to the body and tricuspid and pulmonary valves are on the right side of the heart and they pump venous blood to lungs.
What is Aortic Aneurysm (Dilation) ?
Aorta is the biggest vein in human body. It transfers arterial blood from the heart to all organs which makes it “main blood line”. Considering height and weight of the person, it carries 3 to 6-7 lt. of blood in a minute. There is a certain pressure (80 - 140 mmHg) while transferring the blood depending on heart’s beat rate and structure. We call it tension. Aorta may enlarge silently in the body due to various reasons. It should be diagnosed early.
TAVI Explantation: Is it possible with surgical method?
Case Presentation: Age 78, severe aortic stenosis, cardiac left ventricular ejection fraction (cardiac pumping capacity) is 35%, TAVI (biological aortic valve replacement through inguen) has been performed. Patient’s complaints continued and after 1 month, valve leak is observed (paravalvular leak) and TAVI (2nd implantation) operation is renewed.
Mitral Valve Repair, Closed Method (Under the armpit)
It is proven that valve repair is the best method for Mitral Valve Insufficiency. Whether it is rheumatic or degenerative, mitral valve has to be repaired if it is possible. Long-term clinical studies show that the healthiest and the most effective method with less complication is the “Repair” method.
Remote Patient Monitoring Systems, TUBITAK Project of TOBB ETU University Hospital
Prof. Tayfun Aybek, MD -head of the Cardiovascular Surgery Department at TOBB ETU University – conducted the project of Remote Patient Monitoring Systems and the same University supported the Research and Development studies of this project. Remote Patient Monitoring Systems enable patients to follow their vital parameters (tension, EKG, saturation, hemoglobin, arterial blood gases etc.) after a Cardiac Surgery or Heart Attack. Patients may communicate their doctors instantly through the system.
