Atrial fibrillation is a common cardiac disease of aging. The risk of stroke and bad prognosis increase with age and atrial fibrillation. Compared with younger people, elderly people have higher risks for both thrombosis and bleeding. Stroke prevention with oral anticoagulants is the cornerstone of the management of atrial fibrillation but is often questioned because of the risk of bleeding, furthermore comorbidities, comedications, fall risks, poor compliance. These factors frequently found in frail elderly patients complicate the management of antithrombotic therapy. This article reviews the evidence for the risks and benefits of anticoagulation in the elderly with atrial fibrillation, by comparing the new oral anticoagulants to vitamin K antagonists.

Background: Most older patients with atrial fibrillation (AF) have comorbidities. However, it is unclear whether specific comorbidity patterns are associated with adverse outcomes. We identified comorbidity patterns and their association with mortality in multimorbid older AF patients with different multidimensional frailty.

Risk factors for long-term severe tricuspid regurgitation following mitral valve replacement: a retrospective study.

BMC Cardiovasc Disord

January 2025

Department of Cardiology, Xuzhou Central Hospital, No.199 Jiefang South Road, Quanshan District, Xuzhou, 221009, People's Republic of China.

Background: The aim of this study is to identify factors associated with the development of long-term severe tricuspid regurgitation (TR) following mitral valve replacement (MVR).

Methods: A retrospective analysis was conducted involving 308 patients who underwent single-valve MVR at Xuzhou Central Hospital between April 2017 and December 2022. Preoperative color Doppler ultrasound indicated that all patients had either no or mild to moderate tricuspid regurgitation.

Background: Given the prevalence of cardiovascular disease, encountering difficult airways in this patient population is quite common. The challenge for anesthesiologists lies not only in establishing the airway but also in managing the hemodynamic instability caused by sympathetic activation during intubation. The purpose of this report is to describe the anesthetic experience of this patient with severe mitral and tricuspid regurgitation, atrial fibrillation with rapid ventricular response, and moderate pulmonary hypertension with an anticipated difficult airway.
