Atrial fibrillation (AF) is a devastating disease with a large global prevalence. The left atrial appendage (LAA) is a major source of thrombi in patients with AF. Echocardiography plays an important role in identifying LAA thrombi and has become an invaluable imaging tool in planning for LAA occlusion (LAAO) in patients intolerant to anticoagulation. This review article will discuss the role of echocardiography in selecting patients for LAAO, intraprocedural monitoring, and identifying procedure-related complications.

Risk and Protective Factors of Poor Clinical Outcomes in Heart Failure with Improved Ejection Fraction Population: A Systematic Review and Meta-Analysis.
Curr Cardiol Rep
January 2025
Faculty of Medicine, University of Padjadjaran, Bandung, Indonesia.
Aims: Heart failure with improved ejection fraction (HFimpEF) patients could still develop adverse outcomes despite EF improvement. This study evaluates the risk and protective factors of poor clinical outcomes in HFimpEF patients.
Methods: Systematic searching was done to include studies that evaluate the risks of developing poor outcomes in HFimpEF patients.

Unlabelled: Transposition of the great arteries (Dextro-TGA), repaired with physiological correction techniques (atrial switch - Mustard or Senning surgery), can present as a complication the failure of the right ventricle that acts as systemic and, at the same time, deconditioning of the left ventricle, leading to congestive heart failure. In these patients, treatment and recovery options are very limited.
Objective: To describe successful late anatomical correction after ventricular retraining.
Carotid Body Tumor: Incidental Discovery and Diagnosis.

Carotid body tumors (CBTs), rare neuroendocrine neoplasms near the carotid bifurcation, are mostly asymptomatic but may cause discomfort and autonomic dysfunction. Computed tomography angiography (CTA) is used for diagnosis, eliminating the need for a biopsy to avoid the risk of hemorrhage. Surgical excision is the preferred treatment, while radiotherapy is an option when surgery is impractical.

The relationship between left atrial enlargement (LAE) and primary cryptogenic stroke (PCS) remains a mystery. LAE has been proposed to be an independent risk factor of PCS, recurrent ischemic strokes, paroxysmal atrial fibrillation, and thromboembolism. Our study evaluates the prevalence of LAE among patients with PCS in the absence of atrial fibrillation, unlike previous studies that included atrial fibrillation, in order to isolate LAE as a risk factor.

Background: Given the high prevalence of stage A or B heart failure (HF), comprehensive screening for new-onset HF is cost-prohibitive. Therefore, further risk stratification is warranted to identify at-risk patients. This study aimed to evaluate the prognostic utility of cardiopulmonary exercise test (CPET) with bicycle stress echocardiography (BSE) in patients with stage A or B HF.
