The Role of Left Atrial Imaging in the Management of Atrial Fibrillation

The Role of Multimodality Cardiac Imaging in the Management of Patients with Atrial Fibrillation

“…Preprocedural CT/MRI can also provide valuable information regarding the anatomy of the PV and LA, as well as the presence of contraindications for LA ablation, such as a thrombus or extreme LA dilatation [13,15].…”

“…Before LA ablation, the anatomic variants, ostial diameter, and branching pattern of the PV are evaluated to prevent post-procedural complications, such as PV stenosis, and also to predict outcomes [15,[28][29][30]. This is because PV diameter increases according to the progression of AF, with the largest diameters being seen in persistent AF [28].…”

“…Cardiac CT and cardiac magnetic resonance (CMR) clearly demonstrate PVs. PV venography and transesophageal echocardiography (TEE) underestimate the diameter of the PV [15,28]. The ostial diameter of the PV changes according to the cardiac cycle, decreasing by around 32.5% of the ostial size during atrial systole [33].…”

“…LA volume is a strong and independent predictor of AF recurrence after ablation [11,13,15]. Traditionally, LA dimensions and volumes are measured using echocardiography; its longitudinal diameter is 4.5±1.4 cm, and its transverse diameter is 4.0± 1.2 cm (Fig.…”

Evaluation of atrial remodeling in patients after maze procedure

“…Люди в возрасте старше 40 лет имеют один из факторов риска развития ФП, который чаще встречается в сочетании с преклонным возрастом, артериальной гипер-тензией, сердечной недостаточностью, апноэ во время сна, ожирением, избыточным употребле-нием алкоголя [3][4][5]. Алгоритмом профилактики заболевания и лечения пациентов с ФП являет-ся снижение риска системной тромбоэмболии и контроль частоты ритма [6,7].…”
