![]() ![]() The authors describe the case of a 51-year-old man, referred for a cardiology consultation in 2009 for paroxysmal atrial fibrillation (AF), the first episode of which was documented in December 2008, lasting 18 hours and terminating spontaneously he had no other relevant medical history. Na era da ablação percutânea, é essencial perceber o mecanismo da arritmia e reconhecer a existência destes flutters atípicos. Fez re-ablação da veia recanalizada com sucesso, sem qualquer recorrência arrítmica até ao momento. O estudo eletrofisiológico confirmou o diagnóstico de flutter atípico esquerdo e reaparecimento de atividade elétrica na veia pulmonar inferior direita. Três anos depois, reiniciou queixas de palpitações e foi documentado flutter auricular atípico. Após insucesso da terapêutica antiarrítmica, foi referenciado para ablação percutânea, com critérios de sucesso agudo. Os autores descrevem o caso de um homem, 51 anos de idade, sem antecedentes patológicos conhecidos, encaminhado para a consulta de cardiologia, em 2009, por fibrilhação auricular paroxística. Este tipo de flutter é particularmente frequente após isolamento das veias pulmonares, especialmente após extensa ablação auricular, incluindo lesões e/ou desfragmentação lineares. In an era of frequent catheter ablation it is essential to understand the mechanism of this arrhythmia and to recognize such atypical flutters.Ī existência de cardiopatia estrutural, a história de cirurgia cardíaca prévia (frequentemente envolvendo a aurícula esquerda) e a ablação percutânea da fibrilhação auricular conduziram a um aumento da incidência de taquicardias auriculares regulares, frequentemente apresentando-se como flutters atípicos. This vein was again ablated successfully and there has been no arrhythmia recurrence to date. The electrophysiology study confirmed the diagnosis of atypical left flutter and reappearance of electrical activity in the right inferior pulmonary vein. Three years later he again suffered palpitations and atypical atrial flutter was documented. After failure of antiarrhythmic therapy, he underwent catheter ablation, with criteria of acute success. The authors describe the case of a 51-year-old man, with no relevant medical history, referred for a cardiology consultation in 2009 for paroxysmal atrial fibrillation. This type of flutter is particularly common after pulmonary vein isolation, especially after extensive atrial ablation including linear lesions and/or defragmentation. If this happens, the procedure may be repeated or you and your health care provider might consider other treatments.Cardiac surgery for structural heart disease (often involving the left atrium) and radiofrequency catheter ablation of atrial fibrillation have led to an increased incidence of regular atrial tachycardias, often presenting as atypical flutters. Most people see improvements in their quality of life after this type of cardiac ablation, but there's a chance the atrial flutter may return. ResultsĪfter atrial flutter ablation, you'll need regular checkups to monitor your heart. Afterward, you'll be taken to a recovery area where care providers will closely monitor your condition.ĭepending on your condition, you may be allowed to go home the same day or you may spend a night in the hospital. The scarring helps block the electrical signals that are causing the atrial flutter.Ītrial flutter ablation typically takes two to three hours. Heat (radiofrequency energy) is applied to the target area, damaging the tissue and causing scarring. This information is used to determine the best place to apply the ablation treatment. Sensors on the tip of the catheter send electrical impulses and record the heart's electricity. The doctor inserts a long flexible tube (catheter) into the vein and carefully guides it into your heart. Once the sedative takes effect, a small area near a vein, usually in your groin, is numbed. You'll likely receive a medication to help you relax (sedative). ![]() What you can expectĪtrial flutter ablation is done in the hospital. Atrial flutter ablation may restore a typical heart rhythm, which may improve quality of life. Atrial flutter ablation is done to control the signs and symptoms associated with atrial flutter. ![]()
