In a small number of cases left ventricular assist devices, combined with drug therapy, have enabled the heart to recover sufficiently for the device to be able to be removed (explanted). [ 7 ] [ 8 ] Several surgical approaches, including interventional decommissioning, off-pump explantation using a custom-made plug and complete LVAD removal ...
Ventricular assist devices require open-heart surgery for implantation. An incision is made through the breastbone to expose the heart. Heparin will be given to keep the patients blood from clotting. The blood is rerouted to a heart-lung machine that will pump and oxygenate blood. A pocket for the LVAD is formed in the abdominal wall.
Pump thrombosis (PT) is considered a specific case of a major device malfunction, and is classified as either suspected or confirmed pump thrombus. Typically, the device is an implanted blood pump such as a left ventricular assist device. The malfunction is a blockage in the flow of blood anywhere along a vessel (upstream or downstream) and it ...
More modern devices have software designed to attempt a discrimination between ventricular fibrillation and ventricular tachycardia (VT), and may try to pace the heart faster than its intrinsic rate in the case of VT, to try to break the tachycardia before it progresses to ventricular fibrillation. This is known as overdrive pacing, or anti ...
The FDA approved the OPTIMIZER Smart System, which delivers cardiac contractility modulation therapy, as indicated to improve 6-minute hall walk distance, quality of life, and functional status of NYHA Class III heart failure patients who remain symptomatic despite guideline directed medical therapy, who are in normal sinus rhythm, are not indicated for cardiac resynchronization therapy, and ...
Fellows are trained to provide perioperative anesthetic management for patients with severe cardiopulmonary pathology. Some of the cardiac surgeries they train for include the following: coronary artery bypass surgery (CABG) both on cardiopulmonary bypass as well as on a beating heart, heart valve surgery, aortic reconstruction requiring deep hypothermic arrest, mechanical ventricular assist ...

An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
