Whenever a prosthetic device such as a valve is introduced into the bloodstream, there is an ongoing risk of thrombus formation which can lead to an embolism should the thrombus become mobile. Computational flow studies [ 21 ] conclude that the presence of an aortic valve bypass conduit has no effect on cerebral blood flow.
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Following the bidirectional Glenn shunt, failure of the procedure can be broadly categorized as failure of procedure, cardiac dysfunction related to surgery, or cardiac dysfunction leading to death before further surgical intervention. [8] Retrospective reviews demonstrate failure of the procedure in 6.5% of patients.

A system of coaxial catheters is pushed inside the arterial circulation, usually through a percutaneous access to the right femoral artery. A microcatheter is finally positioned beyond the occluded segment and a stent-retriever is deployed to catch the thrombus; finally, the stent is pulled out from the artery, usually under continuous ...
Furthermore, movement from the heart makes delicate work on the closely attached pulmonary arteries complex. Hypothermia is necessary as the embolus is very delicate and the risk of disruption is high, in order to appropriately visualize the clot and remove it a bloodless field is required. Clot visualization is achieved through dissection of ...
An alternative to open heart surgery, percutaneous valve repair is performed on the mitral valve using the MONARC system or MitraClip system [7] Coronary thrombectomy Coronary thrombectomy involves the removal of a thrombus (blood clot) from the coronary arteries. [8] Open heart surgery of the heart is performed by a cardiothoracic surgeon ...
The purpose of the procedure is to utilize the right ventricle as the main chamber pumping blood to the body and lungs. A connection between left and right atria (collecting chambers of the heart) is established via atrial septectomy, allowing blood arriving from the lungs to travel to the right ventricle.
