Article Abstract
Background: Left atrial appendage (LAA) closure (LAAc) has emerged as a safe and effective alternative to oral anticoagulation (OAC) for stroke prevention in patients with atrial fibrillation (AF) and contraindications to OAC.
Case Summary: A 61-year-old woman with permanent AF and a history of mitral surgery replacement with mechanical prosthesis was referred to our cardiology department to undergo LAAc. The preoperative computed tomography (CT) revealed that the ostium of the LAA was close to the mitral prosthesis ring. As a result of the difficult LAA morphology, a CT image-based virtual model was created, then a 3D printing model was prepared in our laboratory, and procedure simulation was performed with the two different LAA occlusion devices (plug- vs. pacifier-like models) to see which one was more suitable for the patient anatomy.
Discussion: In this case of complex LAAc in a patient with mechanical prosthetic mitral valve, the use of a 3D printed model has guided prosthesis selection and device sizing reducing procedure time and complications.

We recently reviewed the article titled "Outcomes of Bolus Dose Furosemide Versus Continuous Infusion in Patients With Acute Decompensated Left Ventricular Failure and Atrial Fibrillation" published in Clinical Cardiology by [khan et al.] (1) with great interest. This study addresses a crucial area of clinical practice, and we appreciate the authors' efforts in exploring this topic.

Primary liver cancer, predominantly hepatocellular carcinoma (HCC), is a leading cause of cancer-related mortality. Tumor thrombus (TT) in the inferior vena cava (IVC) or right atrium (RA) significantly worsens prognosis. We present four cases of male patients (average age 57) with HCC and TT extending into the IVC/RA, treated at our center.

Introduction: Transposition of the great arteries (TGA), especially with intact ventricular septum (TGA-IVS), presents unique challenges during fetal-to-neonatal transition, which can contribute to developing persistent pulmonary hypertension of the newborn (PPHN).
Case Presentation: A male newborn with TGA-IVS, delivered via caesarean section, presented with hypoxemia and tachycardia immediately after birth (preductal SpO: 50-60%, post-ductal SpO: 70-75%). Echocardiography revealed a floppy interatrial septum and two interatrial connections with bidirectional shunting.
Real-world outcomes in cardiac resynchronization therapy patients: Primary results of the SMART registry.
ESC Heart Fail
December 2024
Boston Scientific Corporation, St. Paul, Minnesota, USA.
Aims: Cardiac resynchronization therapy (CRT) is guideline recommended for the treatment of symptomatic heart failure (HF) with reduced left ventricular ejection fraction and prolonged QRS. However, patients with common comorbidities, such as persistent/permanent atrial fibrillation (AF), are often under-represented in clinical trials.
Methods: The Strategic Management to Optimize Response to Cardiac Resynchronization Therapy (SMART) registry (NCT03075215) was a global, multicentre, registry that enrolled de novo CRT implants, or upgrade from pacemaker or implantable cardioverter defibrillator to CRT-defibrillator (CRT-D), using a quadripolar left ventricular lead in real-world clinical practice.
Identifying early left atrial dysfunction in COPD patients using ECG morphology-voltage-P wave duration score.

Department of Chest Diseases, Faculty of Medicine, Çanakkale Onsekiz Mart University, Canakkale, Turkey.
Background: Chronic Obstructive Pulmonary Disease (COPD) is associated with left atrial (LA) dyfunction, which may contribute to adverse cardiovascular outcomes. This study investigates the predictive value of lately identified morphology-voltage-P wave duration electrocardiography (MVP ECG) score for detecting early LA dysfunction in COPD patients.
Methods: In this cross-sectional study, 101 COPD patients were enrolled.
