After 12 months, participants receiving catheter ablation were more likely to be free of atrial fibrillation, and less likely to need cardioversion. However, the evidence quality ranged from moderate to very low [ 4 ] A 2006 study, including both paroxysmal and non-paroxysmal atrial fibrillation, found that the success rates are 28% for single ...
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
The Amulet device is inserted very similarly to the Watchman LAAC implant. A catheter is introduced into the groin and travels up to the heart where it crosses from the right atrium into the left atrium via a hole in the septum. The device is then discharged into the LAA. Eventually tissue grows over the Amulet device and completely occludes ...
Indications for cardiac catheterization include the following: Heart Attack (includes ST elevation MI, Non-ST Elevation MI, Unstable Angina) Abnormal Stress Test; New-onset unexplained heart failure; Survival of sudden cardiac death or dangerous cardiac arrhythmia; Persistent chest pain despite optimal medical therapy
A blunt cardiac injury is an injury to the heart as the result of blunt trauma, typically to the anterior chest wall. It can result in a variety of specific injuries to the heart, the most common of which is a myocardial contusion , which is a term for a bruise (contusion) to the heart after an injury. [ 1 ]
While sudden cardiac death among young athletes is still relatively rare — an estimated 1 in 50,000 to 1 in 80,000 experience it — researchers have supported having AEDs near playing fields ...
A hybrid cardiac surgical procedure in a narrow sense is defined as a procedure that combines a conventional, more invasive surgical part (including a skin incision) with an interventional part, using some sort of catheter-based procedure guided by fluoroscopy (or other, e.g., CT or MRI) imaging in a hybrid operating room (OR) without interruption. [1]
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
