A patient had a gunshot wound to the heart involving three cardiac chambers. Conventional echocardiography failed to identify the intracardiac injuries. The utility of transesophageal echocardiography in a patient with cardiac trauma is described.

Enhancing Thromboembolic Risk Prediction in Non-valvular Atrial Fibrillation: The Critical Role of Transesophageal Echocardiography (TEE).

Cardiology, Avicenna Military Hospital, Marrakesh, MAR.
Introduction Atrial fibrillation (AF), the most common cardiac arrhythmia, poses challenges in predicting thromboembolic risk. While the CHADS-VASc (congestive heart failure, hypertension, age ≥ 75 years (doubled), type 2 diabetes mellitus, previous stroke, transient ischemic attack, or thromboembolism (doubled), vascular disease, age 65-74 years, and sex category) score remains essential, its limitations include failure to identify left atrial (LA) thrombus in some patients. Transesophageal echocardiography (TEE) provides superior detection of LA thrombi and thrombogenic factors compared to transthoracic echocardiography (TTE), improving risk stratification, especially in intermediate-risk groups.

Background: Although the method of autocalibration or calibration based on catheter diameters was proposed for fluoroscopic measurement during percutaneous left atrial appendage occlusion (LAAO), it may be imprecise and lead to mismeasurement. We sought to investigate whether the utilization of the surface steel ball calibration (SSBC) method under fluoroscopy could facilitate the fluoroscopic measurement of the post-implanted WATCHMAN device (Boston Scientific Corporation, Natick, MA, USA) in LAAO.
Methods: This retrospective study included 97 consecutive patients who underwent percutaneous LAAO with the WATCHMAN device.
Percutaneous Mitral Valve-in-Ring Procedure in a Case of Severe Mitral Regurgitation Repaired with a Surgical Flexible Ring: A Step-by-Step Description.

Severe mitral regurgitation (MR) following surgical repair of the mitral valve poses a significant clinical challenge. Patients who have undergone surgery are typically at high risk for a second operation. This report details the case of a 54-year-old male who underwent aortic valve replacement and mitral valve repair using a 34-ring, 14 years prior.

Department of Cardiology, The Second Affiliated Hospital of Xi'an Jiaotong University, No. 157 Xiwu Road, Xincheng District, Xi'an, Shaanxi 710004, China. Electronic address:
Aims: Glucosamine, a widely used dietary supplement, has been linked to potential cardiovascular risks, including atrial fibrillation (AF). This study aimed to investigate the effects of long-term glucosamine supplementation on AF susceptibility and the underlying mechanisms.
Materials And Methods: C57BL/6 J mice were treated with low-dose (15 mg/kg/day) or high-dose (250 mg/kg/day) glucosamine via drinking water for 6 weeks.
Comparative Analysis of Irrigation Mist and CO vs. Direct CO Blower in On-Pump Coronary Artery Bypass Grafting Anastomosis: Efficacy, Efficiency, and Fibrillation upon De-Clamping and Micro-Embolic Gas Activity Incidence.

In coronary artery bypass grafting (CABG) on pump, achieving optimal visualization is critical for surgical precision and safety. The use of blowers to clear the CABG anastomosis poses risks, including the formation of micro-embolic gas bubbles, which can be insidious and increase the risk of cerebral or myocardial complications. This retrospective study compares the effectiveness of the use of irrigation mist and CO versus a direct CO blower without irrigation in terms of visualization, postoperative fibrillation, and micro-embolic gas activity.
