Department of Ultrasound Medicine, Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, 210008, People's Republic of China.
Objectives: This study aimed to establish standard transesophageal echocardiographic (TEE) measurements of left ventricular (LV) morphology, function, and myocardial work parameters in healthy Beagle dogs using pressure-strain loops (PSL). Additionally, it sought to standardize optimal TEE imaging techniques and explore the potiential application of myocardial work analyis in veterinary medicine.
Methods: Thirty-seven healthy male Beagle dogs were anesthetized, intubated, and mechanically ventilated for TEE examinations.

Cardiovascular and respiratory alterations during anesthesia are of major concern in canines. Thus, it is essential to understand the potential depressant effects of anesthetic drugs on cardio-vascular system; so that, anesthetic procedures are conducted in the best possible way. The objective of the study was to assess and compare the echocardiographic indices during dex-medetomidine and midazolam anesthesia in dogs undergoing elective ovariohysterectomy.

To assess the efficacy and safety of "one-stop" procedures combining radiofrequency catheter ablation and left atrial appendage closure by guidance of intracardiac echocardiography(ICE) in elderly patients with atrial fibrillation. A retrospective cohort study was conducted on patients who underwent ICE-guided "one-stop" procedures at the Department of Cardiology, General Hospital of Northern Theater Command between December 2020 and January 2023. Patients were divided into elderly group (age≥60 years old) and non-elderly group (age 18-59 years old).

Background: In adults with chronic kidney disease (CKD), abnormal left atrial reservoir strain (LASr) is an early, yet clinically significant, indicator of myocardial dysfunction. However, left atrial mechanics are understudied in youth with CKD. The objective of this study was to assess left atrial strain function in youth with CKD and similarly aged, healthy controls.

Aim: Postoperative Atrial Fibrillation (POAF) is a common complication following Coronary Artery Bypass Grafting (CABG), associated with increased morbidity and mortality. Aim of the study is to analyze whether the measurement of preoperative Left Atrial (LA) strain can offer advantages over conventional clinical and echocardiographic parameters to identify patients at risk of developing POAF.
Methods And Results: We conducted a prospective study involving 100 patients undergoing isolated CABG from April 2023 to April 2024.
