Methods Overall, 1739 adult patients with HCM (40.9%
Introduction Catheter ablation is an effective and safe strategy for treating atrialfibrillation patients. Nevertheless, studies on the long-term outcomes of catheter ablation in patients with dilated cardiomyopathy are limited. Among the catheter ablation group, 58.7% ( n = 27) had persistent atrialfibrillation.
When atrialfibrillation (AF) begins, it can start with a single focus, degenerating to multiple wavelets, and it spreads throughout the entire surface area of both atria. A fibrillatory wave that occurs at a rate of more than 600 beats per minute can cause fatigue in the long run, leading to atrial dilation.
Keywords with strong recent citation bursts included tissue, cardiomyopathy, and closed chest ablation.ConclusionPFA is becoming established as a viable alternative for AF ablation, showing promising safety and efficacy. Prolific authors were identified, underscoring significant international collaborations.
Several predictors of atrialfibrillation (AF) onset in patients with hypertrophic cardiomyopathy (HCM) have been proposed, however, all of them showed limited accuracy. This study aims to assess the role of n.
So it must be atrialfibrillation. Answer : it is irregularly irregular and the initial part of the QRS is fast, so this is atrialfibrillation with Left Bundle Branch Block (LBBB). Patient has an ICD, which is primarily placed in patients with cardiomyopathy. What do you think? mm; the S-wave is 18 mm.

Of course, this is NOT atrial fib, but rather PSVT, and so adenosine should work.

Atrialfibrillation(AF) is associated with increased risk of embolic stroke and heart failure hospitalizations in patients with hypertrophic cardiomyopathy(HCM).
Oral diuretic intensification was significantly prognostic of mortality amongst patients with transthyretin cardiomyopathy and occurred more often than HF hospitalization. Patients experiencing ODI had higher rates of subsequent mortality (17.7 per 100 person-years; 95% confidence interval [CI] 13.323.7) per 100 person-years; 95% CI 17.750.3)

Late-breaking Clinical Trial Results from FARADISE, admIRE Study and Advent Trial at Heart Rhythm 2024 Highlight Pulsed Field Ablation Developments for AtrialFibrillation Treatment 8.
Mavacamten is a cardiac myosin inhibitor that has been shown to reduce left ventricular outflow tract obstruction in obstructive hypertrophic cardiomyopathy (oHCM).1 1 In late-stage clinical trials, atrialfibrillation (AF) represented an adverse event in 2-4 % of the patients randomized to mavacamten.1,2
Development of a machine learning model to predict new-onset atrialfibrillation in patients with hypertrophic cardiomyopathy. Aims Atrialfibrillation (AF) is the most common sustained arrhythmia among patients with hypertrophic cardiomyopathy (HCM), leading to increased symptom burden and risk of thromboembolism.
study on the frequency of new-onset and recurrent atrialfibrillation (AF) events in patients with obstructive hypertrophic cardiomyopathy (oHCM) on mavacamten.1 We read with interest Castrichini et al.s
Atrialfibrillation (AF) is common in patients with hypertrophic cardiomyopathy (HCM) and can be challenging to manage. Atrioventricular nodal (AVN) ablation may be an effective management strategy for AF in these patients.
In patients with hypertrophic cardiomyopathy (HCM), atrialfibrillation (AF) poses significant clinical challenges because of its adverse impact on hemodynamics. AF, especially when accompanied by rapid ventricular responses, compromises atrial contraction and in turn increases diastolic filling of the left ventricle.
Efficacy of finerenone according to left atrial size in patients with heart failure and mildly reduced or preserved ejection fraction: An analysis of the FINEARTS-HF trial during the session " Finerenone: A Promising Addition to the Armamentarium or Merely an Academic Exercise?"
Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrialfibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).
Mechanisms and potential targets to manage atrialfibrillation related to diabetes mellitus are represented. ABSTRACT In spite of significant progress made in the management in recent decades, atrialfibrillation (AF) continues to cause increased mortality and significant morbidities, including heart failure and stroke.
Long-term follow-up (FU) of the TRED-HF trial: persistent high-risk of relapse following therapy withdrawal in recovered dilated cardiomyopathy (DCM), likely contributed to by low-dose therapy and exposure to external triggers. LVEF, left ventricular ejection fraction. This follow-up investigates the longer-term effects of therapy withdrawal.
Abstract Introduction In hypertrophic cardiomyopathy (HCM), atrialfibrillation (AF) has historically been regarded to have a deleterious impact on clinical course, strongly associated with progressive heart failure (HF) symptoms. Results Among the 218 patients, 50 (23%) had a history of AF and comprise the primary study cohort.
ABSTRACT Background Atrialfibrillation and atrial flutter are relatively rare in young people and the incidence of thromboembolic complications is unknown. Structural heart disease (SHD) was present in 120 patients (57%) and 20 patients (10%) had a primary cardiomyopathy.
Hypertrophic cardiomyopathy (HCM) stands as one of the most common inheritable myocardial disease and is often marked by its association with sudden cardiac death (SCD) in the young. 1 2 Traditionally, risk assessment in HCM has focused mainly on estimating the likelihood of SCD.
Cardiomyopathies: These diseases affect the heart muscle, impairing its ability to pump blood effectively. Mutations in specific genes often cause hypertrophic cardiomyopathy and dilated cardiomyopathy.
