Metrics details. The primary aim was to observe the predictive value of P-wave ECG index and left atrial appendage volume LLAV for atrial fibrillation recurrence after first radiofrequency catheter ablation. A total of patients with paroxysmal atrial fibrillation were enrolled. According to the follow-up results, the patients were divided into two groups: the non-recurrence group and the recurrence group. Kaplan—Meier curve analysis showed that the survival rate without recurrence of atrial fibrillation after catheter ablation was lower when the LLAV exceeded 8. The combination might be a valid and alternative independent predictor of recurrence.
Atrial Fibrillation: Current Management and Best Practices
Atrial fibrillation - Symptoms and causes - Mayo Clinic
Atrial fibrillation AF or A-fib is an abnormal heart rhythm arrhythmia characterized by the rapid and irregular beating of the atrial chambers of the heart. High blood pressure and valvular heart disease are the most common alterable risk factors for AF. Healthy lifestyle changes, such as weight loss in people with obesity, increased physical activity, and drinking less alcohol , can lower the risk for atrial fibrillation and reduce its burden if it occurs. Atrial fibrillation is the most common serious abnormal heart rhythm and, as of , affects more than 33 million people worldwide. AF is usually accompanied by symptoms related to a rapid heart rate. Rapid and irregular heart rates may be perceived as the sensation of the heart beating too fast, irregularly, or skipping beats palpitations or exercise intolerance and occasionally may produce anginal chest pain if the high heart rate causes the heart's demand for oxygen to increase beyond the supply of available oxygen ischemia. Other possible symptoms include congestive heart failure symptoms such as fatigue, shortness of breath , or swelling.
Causes and Risk Factors of Atrial Fibrillation
Atrial fibrillation is an irregular and often rapid heart rate that can increase your risk of strokes, heart failure and other heart-related complications. During atrial fibrillation, the heart's two upper chambers the atria beat chaotically and irregularly — out of coordination with the two lower chambers the ventricles of the heart. Atrial fibrillation symptoms often include heart palpitations, shortness of breath and weakness. Episodes of atrial fibrillation may come and go, or you may develop atrial fibrillation that doesn't go away and may require treatment. Although atrial fibrillation itself usually isn't life-threatening, it is a serious medical condition that sometimes requires emergency treatment.
Background: Catheter ablation CA is a well-known treatment option for patients with symptomatic drug-resistant atrial fibrillation AF. Multiple factors have been identified to determine AF recurrence after CA, however their predictive value is rather small. Identification of novel predictors of CA outcome is therefore of primary importance to reduce health costs and improve long-term results of intervention. The recurrence of AF following CA is related to severity of left ventricular LV dysfunction, extent of atrial dilatation and fibrosis. The aim of this paper was to present and discuss the latest studies on the utility of echocardiographic parameters in terms of CA effectiveness in patients with paroxysmal and persistent AF.
