Cardiac Magnetic Resonance in the Assessment of Atrial Cardiomyopathy and Pulmonary Vein Isolation Planning for Atrial Fibrillation.

Atrial fibrillation (AF) is the most frequently observed type of arrhythmia among adults, and its absolute prevalence is steadily rising in close association with the aging of the population, with its prevalence varying from 2% in the general population to 10-12% among the elderly. The relatively new concepts of 'atrial cardiomyopathy' and "AF-related atrial cardiomyopathy", along with the growing body of knowledge regarding remodeling, function, and tissue characterization, highlight the need for novel approaches to the diagnostic process as well as in the therapeutic guidance and monitoring of atrial arrhythmias. Advanced imaging techniques, particularly cardiac magnetic resonance (CMR) imaging, have emerged as pivotal in the detailed assessment of atrial structure and function.

Rationale and design of the CT-STEMI study (Cardiac Computed Tomography for comprehensive risk stratification of arrhythmic, atherothrombotic and heart failure events following reperfused ST-segment Elevation Myocardial Infarction).

Background: ST-segment elevation myocardial infarction (STEMI) remains a major cause of morbidity and mortality, with survivors facing high risk of heart failure, recurrent ischemia, and arrhythmias. Risk stratification traditionally relies on echocardiography, while cardiac magnetic resonance (CMR) is the most effective tool for predicting adverse outcomes. However, its routine use is limited by accessibility, cost, and logistical constraints.

An aortopulmonary septal defect or aortopulmonary window (APW) is a rare cardiovascular anomaly with direct communication between the ascending aorta and the main pulmonary artery leading to a left-to-right shunt. It is accompanied by other cardiovascular anomalies in approximately half of patients. In order to avoid irreversible sequelae, interventional or surgical treatment should be performed as soon as possible.
