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.
The Watchman procedure helps those with atrial fibrillation (AFib). Medicare covers the surgery for eligible beneficiaries. AFib is a common heart rhythm disorder consisting of rapid and irregular ...
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.
Watchman camera, a system of cameras for controlling traffic and deterring speeding in the United Kingdom; Watchman device, a type of left atrial appendage occlusion system to prevent blood clot formation in certain heart rhythm disturbances; Watchman Island, a small sandstone island in the Waitemata Harbour of Auckland, New Zealand
From the right atrium, visualization of the interatrial septum, all four cardiac chambers, all four valves, and the pericardial space (for an effusion) can be readily visualized. It can also be advanced across the atrial septum into the left atrium to visualize the left atrial appendage during left atrial appendage occlusion device deployment.
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]
The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart. After the left atrium fills with blood, the mitral valve allows blood to flow from the left atrium into the heart's main pumping chamber called the left ...
Totally endoscopic coronary artery bypass surgery (TECAB) is an entirely endoscopic robotic surgery used to treat coronary heart disease, developed in the late 1990s.It is an advanced form of minimally invasive direct coronary artery bypass surgery, which allows bypass surgery to be conducted off-pump without opening the ribcage.
