Atrial fibrillation is an abnormal cardiac rhythm characterized by inhomogeneous contraction and relaxation of the atria.
These result in a stagnant flow of blood in the heart leading to clot formation in the minor or major heart chambers. As a consequence, the risk of stroke and thromboembolsim is substantial in patients with atrial fibrillation.
At the time of operation including mitral valve repair, our cardiac surgeons generally offer a change of cardiac rhythm, from atrial fibrillation to normal sinus rhythm by means of changing the direction of cardiac electricity by creating lines (Cryo/ablation) in the atria. The advantage of maze procedure is to eliminate a need for long term anticoagulation. We achieve a number of successes with this type of operation.
We provide the best service to our patients from the funding we receive. However, the high demands for medical equipments and supports mean that donations make a very important difference.
