Cardiac MRI to Manage Atrial Fibrillation

MRI in cardiac electrophysiology: the emerging role of delayed-enhancement MRI in atrial fibrillation ablation.

Catheter ablation of atrial fibrillation has emerged as a viable therapeutic option for those patients who have failed conventional medical therapy. This treatment strategy has been introduced in the past decade following the discovery of ectopic foci in the pulmonary veins capable of initiating this arrhythmia. The basis of current ablation techniques relies on inducing myocardial necrosis at ...

Atrial fibrillation in Cardiac Channelopathies

Atrial fibrillation is the commonest arrhythmia encountered in day-to-day clinical practice. Its prevalence is increasing due to increasing age of the population, increasing prevalence of chronic heart disease and better diagnostic techniques. It is an extremely costly public health problem. It increases stroke, heart failure and mortality. Mortality is doubled by the presence of atrial fibrill...

Atrial fibrillation after cardiac surgery.

trial fibrillation (AF) after cardiac surgery is a major cause of morbidity and mortality, and it has been reported that the rate of occurrence is 18–40%.1–5 Various causes have been studied, including advanced age, body mass index, obesity, left atrial dimensions, cardiac dysfunction, chronic respiratory failure, renal dysfunction, fluid balance, preoperative medications, inflammation, and fib...

Atrial Fibrillation in Cardiac Sarcoidosis.

Sarcoidosis is a systemic granulomatous disease that affects the myocardium. Although ventricular arrhythmias are well known manifestations of cardiac involvement, there is increasing evidence that a significant proportion of patients with cardiac sarcoidosis (CS) also have atrial arrhythmias, atrial fibrillation being the most frequent. The incidence and mechanism of atrial fibrillation in CS ...
