Pulmonary veins stenosis relief after an inappropriate radiofrequency catheter ablation of atrial fibrillation in a young non-competitive athlete

One of the major complications of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) is pulmonary vein stenosis (PVS). The natural history of PVS, especially when it involves more than one vein, leads to severe and irreversible pulmonary hypertension with end-stage right heart failure that can require, in extreme cases, even heart-lung transplantation. We report the case of a young patient who underwent RFCA for a single lasting episode of AF and developed PVS years later. He was treated with ballon venoplasty followed by stent implantation in left pulmonary vein because of PVS relief. This reported case emphasizes the need of an adequate indication for RFCA for AF, considering the benefit-risk ratio especially in young patients with normal cardiac function

Diagnosis and Management of Left Atrium Appendage Thrombosis in Atrial Fibrillation Patients Undergoing Cardioversion

Atrial fibrillation is the most common cardiac arrhythmia and is associated with an increased risk of stroke and thromboembolic complications. A rhythm control strategy with both electrical and pharmacological cardioversion is recommended for patients with symptomatic atrial fibrillation. Anticoagulant therapy for 3–4 weeks prior to cardioversion is recommended in order to avoid thromboembolic events deriving from restoring sinus rhythm. Transesophageal echocardiography has a pivotal role in this setting, excluding the presence of left atrial appendage thrombus before cardioversion. The aim of this review is to discuss the epidemiology and risk factors for left atrial appendage thrombosis, the role of echocardiography in the decision making before cardioversion, and the efficacy of different anticoagulant regimens on the detection and treatment of left atrial appendage thrombosis

"A Tale of Two Cities": Anticoagulation Management in Patients with Atrial Fibrillation and Prosthetic Valves in the Era of Direct Oral Anticoagulants

Valvular heart disease and atrial fibrillation often coexist. Oral vitamin K antagonists have represented the main anticoagulation management for antithrombotic prevention in this setting for decades. Novel direct oral anticoagulants (DOACs) are a new class of drugs and currently, due to their well-established efficacy and security, they represent the main therapeutic option in non-valvular atrial fibrillation. Some new evidences are exploring the role of DOACs in patients with valvular atrial fibrillation (mechanical and biological prosthetic valves). In this review we explore the data available in the medical literature to establish the actual role of DOACs in patients with valvular heart disease and atrial fibrillation

Left Ventricular Assist Device Implantation in a Thrombosed Apical Aneurysm

Left ventricular assist device implantation is a challenging procedure in the presence of a giant thrombosed aneurysm, and no standard surgical techniques are currently recommended in this setting. In this case, we report the successful implantation of a left ventricular assist device (HeartMate III) in a patient with a massive thrombosed apical aneurysm. The patient presented with extended antero-apical necrosis as a result of a delay in hospital admission for acute coronary syndrome due to the patient’s concerns about the COVID-19 pandemic outbreak

Update on Direct Oral Anticoagulants in Atrial Fibrillation Patients Undergoing Cardiac Interventional Procedures: From Clinical Trials to Real-World Evidence

Direct oral anticoagulants (DOACs) are considered a first-line therapy for long-term stroke prevention in patients with nonvalvular atrial fibrillation (AF) and high thromboembolic risk. The potential role of DOACs in cardiac interventional procedures is a pressing clinical question, considering the increasing number of procedures and the growing prevalence of patients in DOAC therapy. The aim of this review is to provide an update on available evidence about the clinical performance of DOACs in AF patients undergoing different interventional procedures (AF cardioversion and ablation, and percutaneous coronary and structural heart disease interventions) and to explore the possible role of DOACs as an alternative therapeutic strategy in cardiac interventional procedures among non-AF patients

Use of sacubitril/valsartan as 'bridge to transplant' in patients with end-stage hypertrophic cardiomyopathy

The end stage or burned-out phase is an uncommon but challenging clinical evolution of hypertrophic cardiomyopathy (HCM). The management of end-stage HCM is empirically based on the use of drugs approved for heart failure with reduced ejection fraction; however, cardiac transplantation often represents the best option to improve survival. In our case, we describe the use of sacubitril/valsartan as a 'bridge to transplant' in a patient with end-stage HCM. After introducing the drug, enhancements in functional capacity, a reduction in natriuretic peptides and an increase in left ventricular ejection fraction occurred. Given their improved volume of oxygen consumption (VO2) peak and hemodynamic parameters, our patient was left off the waiting list for cardiac transplant and continues to be regularly followed-up with every 3 months

Clinical Outcome of Edoxaban vs. Vitamin K Antagonists in Patients with Atrial Fibrillation and Diabetes Mellitus: Results from a Multicenter, Propensity-Matched, Real-World Cohort Study

Diabetes mellitus (DM) is a chronic metabolic disease which is independently associated with unfavorable clinical outcomes in patients with atrial fibrillation (AF). Few real-world data are available about the clinical performance of non-vitamin K oral anticoagulants (NOACs) among patients with atrial fibrillation and diabetes. The aim of our propensity score-matched cohort study was to compare the safety and effectiveness of Edoxaban versus well-controlled vitamin K antagonists (VKAs) therapy among this population. In this study, we considered patients with AF and diabetes on Edoxaban or VKAs therapy included in the multicenter Atrial Fibrillation Research Database (NCT03760874). The occurrence of major bleedings (MB) and thromboembolic events (a composite of ischemic stroke, transient ischemic attack, systemic embolism) was respectively considered primary safety and effectiveness outcome. We identified 557 AF patients with diabetes who received Edoxaban (n: 230) or VKAs (n: 327) treatment. After propensity score matching analysis, 135 Edoxaban and 135 VKA recipients with similar clinical characteristics were evaluated. The mean follow-up was 27 ± 3 months. The incidence rate of thromboembolic events (TE) was 3.0 per 100 person-years (1.11 in Edoxaban vs. 1.9 in the VKA group, hazard ratio (HR): 0.59; 95% confidence interval (CI), 0.14 to 2.52; p = 0.48). The incidence rate of major bleedings (MB) was 3.7 per 100 person-years (1.2 in Edoxaban vs. 2.7 in the VKA group, HR: 0.43; 95% CI, 0.10 to 1.40; p = 0.14). The incidence rate of intracranial hemorrhage was 0.35 per 100 person-years in Edoxaban vs. 0.74 in the VKA group (HR: 0.49; 95% CI: 0.05 to 5.54; p = 0.56). A positive net clinical benefit (NCB) of Edoxaban over VKAs was found (+1.39). Insulin therapy (HR: 1.76, p = 0.004) and glycated hemoglobin (HR: 1.17, p = 0.002) were found to be independent predictors of TE; moreover, the concomitant use of antiplatelet drugs (HR: 2.41, p = 0.001) was an independent predictor of MB. Conclusions: Our data support the hypothesis of the safety and efficacy of Edoxaban for use in patients with AF and diabetes, justified by a favorable NCB over VKAs

Appropriate ICD Interventions for Ventricular Arrhythmias Are Predicted by Higher Syntax Scores I and II in Patients with Ischemic Heart Disease

The occurrence of ventricular arrhythmias (VAs) in ischemic heart disease (IHD) patients is related to the presence and extent of fibrotic/scar tissue. As coronary atherosclerosis is the underlying cause of myocardial ischemia and fibrosis, in IHD patients implanted with an implantable cardioverter defibrillator (ICD) we investigated the relation between the VA burden and the complexity of coronary atherosclerotic lesions
