12/22/2023 0 Comments Atrial flutter ablation location![]() Ablation of this rhythm targets a critical portion of the circuit know as the cavotricuspid isthmus (CTI) it is to this area bounded by the tricuspid valve and the inferior vena cava (IVC) that a linear ablation lesion can be delivered with successful interruption and termination of the circuit. Animated illustration of the electrical circuit in the right atrium during typical atrial flutter. Conditions that lead to right-sided heart dilation and increased pressure can increase the incidence of this rhythm disturbance (right-sided heart failure, pulmonary hypertension, COPD, hypertension, obesity, tricuspid or pulmonary stenosis).įigure 1. It can occur in patients with no structural heart disease (lone atrial flutter), but is more likely in those with a history of prior cardiac surgery, congestive heart failure, or congenital heart disease. The heartbeat on exam is typically fast, but with medications, it can be slow with either a regular or irregular pulse.Ītrial flutter is the result of a rapid electrical circuit localized to the top right heart chamber, the right atrium. This electrical circuit has been extensively mapped using electrophysiology-guided catheter mapping techniques. The atria can contract anywhere from 250-400 beats per minute, with the AV node serving as the “traffic control” preventing 1 to 1 conduction to the ventricles. The Mayo Clinic Health System has dozens of locations in several states.Atrial flutter, another type of supraventricular tachycardia, produces a heart rhythm with typically more atrial contractions than ventricular beats. Mayo Clinic has major campuses in Phoenix and Scottsdale, Arizona Jacksonville, Florida and Rochester, Minnesota. Learn more about Mayo Clinic's cardiovascular surgery and cardiovascular medicine departments' expertise and rankings. With Mayo Clinic's emphasis on collaborative care, specialists at each of the campuses - Minnesota, Arizona and Florida - interact very closely with colleagues at the other campuses and the Mayo Clinic Health System. Mayo Clinic in Rochester, Minnesota, Mayo Clinic in Phoenix/Scottsdale, Arizona, and Mayo Clinic in Jacksonville, Florida, are ranked among the Best Hospitals for heart care and heart surgery by U.S. Mayo Clinic care providers evaluate and treat more than 6,000 people with atrial flutter each year. Mayo Clinic cardiologists, cardiovascular surgeons and others have extensive experience and expertise in diagnosing and treating people with all types of heart rhythm conditions, including atrial flutter. Treatment for atrial flutter at Mayo Clinic can involve medication, cardiac ablation, cardioversion or other advanced treatment options, depending on the specific condition. Tests may include an electrocardiogram (ECG or EKG), chest X-ray, echocardiogram, Holter monitor, event recorder and a stress test. They may order several tests to determine the cause and severity of atrial flutter and determine the most appropriate treatment for the condition. Mayo Clinic doctors trained in heart rhythm conditions have experience diagnosing and treating atrial flutter and other heart rhythm conditions. Mayo Clinic providers use advanced imaging and mapping techniques that allow them to make prompt and accurate diagnoses, which may include referral to the Electrophysiology Laboratory. In Mayo Clinic's Heart Rhythm Clinic, care providers work together as a multidisciplinary team to evaluate and treat people with a wide variety of heart rhythm disorders, including atrial flutter. Providers spend time to learn about you and work with you to provide a personalized treatment plan - care tailored to your specific needs. Mayo Clinic provides care for you as a whole person. ![]()
