What Is Mitral Regurgitation? Mitral regurgitation (MR) occurs when the heart's mitral valve does not close completely, allowing blood to regurgitate (or leak) through the valve when it should be closed. Here is a brief review of the heart's chambers and valves.
A tracheostomy usually takes 20 to 45 minutes to perform. The surgeon or other health care professional will make a cut through the lower front part of your neck and then cut into your windpipe. Cuffed trach tubes may be used. These tubes use air to widen or narrow the tube to fit the hole.
An inflammatory condition, also involving the larynx and bronchi, called croup can result in a barking cough. A tracheotomy is often performed for ventilation in surgical operations where needed. Intubation is also carried out for the same reason by the inserting of a tube into the trachea. From 2008, operations have transplanted a windpipe grown by stem cells, and synthetic windpipes; their success is however doubtful.
