The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.
The Cox maze procedure, also known as maze procedure, is a type of heart surgery for atrial fibrillation. "Maze" refers to the series of incisions arranged in a maze -like pattern in the atria . Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures , are used.
It has been clearly demonstrated that longer or more intensive follow-up identifies much more recurrent atrial fibrillation, [18] hence a procedure with more careful follow-up will appear to be less successful. In addition, procedures continue to evolve rapidly, so long follow-up data do not accurately reflect current procedural methods.
He is most well known for being the principal investigator of the SIRS (Steroids in Cardiac Surgery) trial and the LAAOS III (Left Atrial Appendage Occlusion Study) trial. [1] On April 9, 2015, Whitlock and his team performed the first transcatheter aortic valve implantation on a pregnant woman in the world. [2]
Rotation of the catheter to a "home view" of the left atrium through the mitral valve into the left ventricle. From there, a 180° rotation will face the posterior wall and posterior deflection will bring the left atrial appendage into view and can be used for deployment of a left atrial appendage occlusion device.
Left atrial appendage occlusion devices; Additionally, there are, at times, indications to remove these devices and extraction (ie, removal) of these devices can also be performed by electrophysiologists. Once implanted, long-term clinical follow up and reprogramming of implanted devices also falls to the electrophysiologist.
Puskas performs cardiovascular surgical procedures including all-arterial coronary bypass grafting, minimally invasive robotic coronary bypass surgery, hybrid coronary revascularization, off-pump coronary artery bypass surgery, ablation surgery for the treatment of atrial fibrillation, mitral valve repair/replacement, aortic valve replacement ...
There is growing evidence that left atrial appendage occlusion therapy may reduce the risk of stroke in people with non-valvular AF as much as warfarin. [154] [155] The addition of left atrial appendage isolation to catheter ablation has reduced AF recurrence by 80% in patients with persistent AF. [156]
