A 71-year-old male presented with recurrent atrial fibrillation, anaemia and thrombocytopenia. Six months ago he underwent an urgent triple coronary artery bypass-grafting elsewhere. Postoperatively he complained of fatigue and low-grade fever. Echocardiographs and magnetic resonance imaging showed a right atrial appendage mass, which afterwards was resected. Histology confirmed a benign myxoma. Patient's symptoms spontaneously resolved. This report demonstrates the unusual sites that myxoma may occur, with probable serious complications in case of urgent heart operations. This case also emphasizes the need for preoperative echocardiography in open heart operations or in cases with recurrent atrial fibrillation.

Usefulness of Artificial Pneumothorax during Totally Endoscopic Off-Pump Left Atrial Appendage Closure and Surgical Ablation.
Ann Thorac Cardiovasc Surg
January 2025
Department of Cardiovascular Surgery, Kobe University, Kobe, Hyogo, Japan.
Purpose: In totally endoscopic off-pump left atrial appendage (LAA) closure and surgical ablation, securing the operative field is sometimes difficult in some patients because of a narrow working space caused by an elevated diaphragm or ventricles. In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax.
Methods: We analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation.
Left Atrial Appendage Occlusion in Patients With Atrial Fibrillation and Hemodialysis: An International, Multicentric Registry.

Cardioangiologisches Centrum Bethanien, Agaplesion Markus-Krankenhaus, Frankfurt am Main, Germany.
Background: The net benefit of oral anticoagulation in patients with end-stage renal disease on hemodialysis (HD) is uncertain. In recent years, left atrial appendage closure (LAAC) has emerged as an alternative to oral anticoagulation; however, there is scant evidence of LAAC in patients on HD.
Objectives: This study aimed to assess the feasibility and safety of LAAC in patients on HD.

Background: In patients with structurally normal hearts, algorithms using surface electrocardiographic P-wave morphology are helpful to predict focal atrial tachycardia (FAT) location. However, these algorithms have not been formally assessed in patients with adult congenital heart disease (ACHD).
Objectives: This study sought to assess the efficacy of FAT-location prediction algorithms in an adult population of patients with ACHD.
"Breaking the Bleed" Spontaneous Hemorrhage in an Emphysematous Bulla Complicated by Anticoagulation: A Case Report.

We present a case of spontaneous hemorrhage in an emphysematous bulla, complicated by anticoagulation. Bullous emphysema is a well-recognized complication of chronic obstructive pulmonary disease (COPD), and a rare manifestation is hemorrhage into preexisting pulmonary bullae. A 69-year-old male patient presented to the emergency department with hemoptysis, shortness of breath, and productive cough.

Introduction: Decreased left atrial appendage emptying velocity (LAAV) is a marker for thrombus formation. This study evaluates the association between LAAV and inflammatory indices in non-valvular atrial fibrillation (AF) patients.
Methods: The study population was 1428 patients with AF, 875 of whom enrolled.
