AI Article Synopsis
- The report evaluates the effectiveness and safety of using intracardiac ultrasound and electrographic guidance for isolating pulmonary veins in patients with atrial fibrillation.
- A left common pulmonary vein was identified in 43% of the patients involved in the study.
- After nearly 550 days of follow-up, 80% of patients remained free from atrial fibrillation, with minimal complications observed, as only one patient showed stenosis without symptoms.
Article Abstract
This report summarizes the efficacy, safety, and feasibility of intracardiac ultrasound (ICUS) and local electrographic-guided pulmonary vein (PV)-left atrial disconnection, including the isolation of common PV trunks accomplished in 170 consecutive patients with atrial fibrillation (AF). A left common PV was found in 43% of patients with AF. During a follow-up of 549 +/- 330 days after ablation, the AF-free survival rate was 80% and comparable in paroxysmal and persistent AF. PV stenosis was detected in only 1 asymptomatic patient, who required no intervention.

Prognostic value of left atrioventricular coupling index in heart failure.
Eur Heart J Cardiovasc Imaging
January 2025
Heart Institute, Department of Cardiology. Germans Trias i Pujol University Hospital, Barcelona,Spain.
Aims: To investigate the distribution of left atrioventricular coupling index (LACI) among patients with heart failure and left ventricular ejection fraction (LVEF)<50% and to explore its association with the combined endpoint of all-cause death or HF hospitalization at long term follow-up.
Methods And Results: Patients with HF and LVEF<50% undergoing cardiac magnetic resonance (CMR) were evaluated. Patients with atrial fibrillation or flutter were excluded.

Department of Anesthesiology, Yanbian University Hospital, Yanji, Jilin, P.R. China.
Rationale: Patients with atrial fibrillation and a large goiter have high perioperative risks and often cannot tolerate general anesthesia, making it necessary for us to explore new safe and effective anesthesia methods.
Patient Concerns: The patient presented with atrial fibrillation accompanied by rapid ventricular rate, a thrombus attached to the left atrial appendage, and a massive thyroid goiter compressing the airway.
Diagnosis: After the left humerus fracture surgery, the patient's internal fixation loosened and fractured, accompanied by infection, formation of sinus tracts, and suppuration.

Department of Emergency, The First Hospital of China Medical University, No. 155, Nanjing North Street, Heping District, Shenyang, 11001, China.
Purpose: This study examines the link between high occupational noise exposure and atrial fibrillation (AF), given the limited existing evidence.
Methods: We conducted a cross-sectional study among participants from a large heavy industry enterprise in China. High noise exposure was defined as an equivalent A-weighted sound level (LAeq, 8 h) of ≥ 80 dB(A) during an 8 h workday.

Pol Arch Intern Med
January 2025
Introduction: Atrial fibrillation (AF) is the most prevalent form of cardiac arrhythmia worldwide. Early diagnosis and treatment are essential, emphasizing the need to develop novel biomarkers. Lipoprotein(a) [Lp(a)] has recently been widely investigated as a potential risk factor for various cardiovascular conditions, including AF.
