Getting to the right left atrium: Catheter ablation of atrial fibrillation and mitral annular flutter in cor triatriatum
نویسندگان
چکیده
Cor triatriatum is a rare congenital cardiac anomaly that is characterized by a thin membrane separating the left atrium both functionally and anatomically. Patients with cor triatriatum are at risk for atrial arrhythmias, which can be especially symptomatic owing to a functional mitral stenosis physiology. We present a case of a patient with cor triatriatum and drug-refractory atrial fibrillation (AF) and atrial flutter (AFl) requiring imaging-guided ablation in both partitions of the left atrium.

Successful Multi-chamber Catheter Ablation of Persistent Atrial Fibrillation in Cor Triatriatum Sinister
Cor triatriatum sinister is a rare congenital cardiac anomaly with an incidence of between 0.1 and 0.4% [1,2] whereby the left atrium is functionally and anatomically divided into two separate chambers by a thin membrane. Although there are a limited number of reports of successful ablation of left atrial focal tachycardia and simple pulmonary vein isolation in individuals with cor triatriatum ...

Cor triatriatum is an acyanotic congenital heart disease. We present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. The 2D transthoracic echocardiography and the Doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium through restrictive opening to the low-pressure, dis...

A 58-year-old man with hypertension and diabetes with recurrent persistent symptomatic atrial fibrillation resistant to sotalol-facilitated cardioversions was referred for ablation. Catheter-based radiofrequency ablation for persistent atrial fibrillation was performed, which consisted of isolation of all 4 pulmonic veins; linear ablations along the left atrial roof; an ablation line from the l...

A 72-year-old woman was admitted to our department for further investigation of a heart defect noted in transtho-racic echocardiography performed in a district hospital. The patient complained of palpitations and moderately limited physical activity. On ECG, atrial fibrillation was recorded with a well-controlled ventricular rate. The chest x-ray demonstrated an enlarged heart and signs of mode...
متن کاملRestoration of Atrial Mechanical Function after Successful Radio-Frequency Catheter Ablation of Atrial Flutter
BACKGROUND Atrial mechanical dysfunction and its recovery time course after successful radiofrequency ablation of chronic atrial flutter (AFL) has been largely unknown. We serially evaluated left atrial function by echocardiography after successful ablation of chronic atrial flutter. METHODS In 13 patients with chronic AFL, mitral E wave A wave, and the ratio of A/E velocity were measured at ...
