Atrial Flutter Market and Epidemiology Analysis

• The rising cases of atrial flutter are mainly due to the increasing prevalence of underlying risk factors such as hypertension, ischemic heart disease, heart failure, and structural heart abnormalities. Additionally, the aging population, improved diagnostic capabilities, and heightened clinical awareness have contributed to a greater identification of cases, further driving the apparent rise in atrial flutter prevalence.
• Atrial flutter treatment focuses on early rhythm or rate control, based on severity and risk factors. Stable cases may need oral drugs, while severe episodes often require cardioversion or ablation. Anticoagulation is standard, and poor response may suggest progression to atrial fibrillation.
• The current atrial flutter treatment landscape has limited competition, with few approved therapies such as RAPIBLYK/ONOACT (landiolol hydrochloride), among others.
• A key unmet need is the early identification of patients at high risk of progressing from atrial flutter to atrial fibrillation. Current tools lack precision in detecting underlying atrial disease, limiting proactive interventions. Improved risk stratification through biomarkers and atrial substrate mapping could enable more effective, personalized management and prevent long-term complications.
• The emerging pipeline for atrial flutter remains largely non-competitive, reflecting a significant gap in innovation. Among the few late-stage candidates, abelacimab shows strong potential to address this unmet need.
• Currently in Phase III under the LILAC-TIMI 76 trial for the prevention of stroke and systemic embolism in atrial fibrillation, abelacimab is anticipated to complete the study in the second half of 2026. Its advancement highlights a strategic push toward improving outcomes and broadening therapeutic options in a space with limited progress.

Atrial Flutter Disease Understanding

Atrial flutter is a prevalent form of supraventricular arrhythmia, originating from abnormal electrical activity in the atria—the heart’s upper chambers. It is characterized by a rapid yet regular atrial rhythm, typically resulting from a reentrant circuit within the right atrium. This arrhythmia arises due to disrupted or aberrant conduction pathways that lead to organized but excessively fast electrical impulses, impairing effective atrial contraction and potentially compromising hemodynamic stability.

Atrial flutter may be asymptomatic in some individuals, while others experience symptoms due to reduced cardiac efficiency. These can include shortness of breath, dizziness, fatigue, palpitations, rapid pulse, chest pain, lightheadedness, or syncope. Such manifestations result from the heart’s inability to maintain effective hemodynamics during rapid atrial contractions.

Atrial Flutter Diagnosis and Treatment Algorithm 

Atrial flutter is diagnosed through a combination of clinical assessment and ECG confirmation. Common symptoms include palpitations, fatigue, and shortness of breath. A characteristic saw tooth pattern on ECG confirms the diagnosis. In intermittent cases, Holter monitoring or electrophysiological studies may be used.

Atrial flutter treatment targets both the arrhythmia and its underlying cause. Medications such as beta-blockers, calcium channel blockers, antiarrhythmics, and anticoagulants are commonly used to control rate, restore rhythm, and prevent stroke. When drugs are ineffective or not tolerated, cardioversion or catheter ablation may be employed. Device adjustments, like pacemaker or ICD reprogramming, can also help manage rhythm disturbances.

Atrial Flutter Drug Analysis

Marketed Atrial Flutter Drugs

• RAPIBLYK/ONOACT (landiolol hydrochloride): AOP Orphan Pharmaceuticals /ONO PHARMACEUTICAL

RAPIBLYK is a highly selective beta-1-adrenoreceptor antagonist that counteracts the positive chronotropic effects of catecholamines—epinephrine and norepinephrine—on the heart, where beta-1 receptors are primarily concentrated. At the approved dosage, landiolol shows no membrane-stabilizing or intrinsic sympathomimetic activity in vitro. Clinically, RAPIBLYK is indicated for the short-term reduction of ventricular rate in adults with supraventricular tachycardia, including atrial fibrillation and atrial flutter.

Following its availability in Europe and Japan, landiolol hydrochloride has now entered the US market. In November 2024, the US FDA approved RAPIBLYK for the rapid ventricular rate control in adults with supraventricular tachycardia, including atrial fibrillation and atrial flutter. Backed by data from five placebo-controlled trials, RAPIBLYK offers a rapid onset of action with minimal effect on blood pressure, positioning it as a valuable option for acute rate management.

Emerging Atrial Flutter Drugs

The Atrial Flutter Market is expected to experience gradual changes, mainly due to the limited availability of emerging therapies in this area. The leading Atrial Flutter Companies such as Anthos Therapeutics have demonstrated a keen interest in this condition and are actively pursuing the development of potential treatments.

• Abelacimab: Anthos Therapeutics

Abelacimab is a novel, fully human monoclonal antibody that binds Factor XI in its inactive state, delivering dual inhibition of Factor XI and XIa. By decoupling thrombosis from hemostasis, it represents a promising anticoagulation approach with a lower risk of bleeding.

Anthos Therapeutics has continued to advance its Factor XI inhibitor abelacimab with compelling data from the pivotal AZALEA-TIMI 71 study. First published in the New England Journal of Medicine (NEJM) in January 2025, following its late-breaking presentation at the 2023 American Heart Association (AHA) meeting, the study gained further momentum with two additional analyses presented at the American College of Cardiology Annual Scientific Session (ACC.25) in March 2025. These analyses reinforced abelacimab’s ability to significantly reduce bleeding risk across age groups and baseline bleeding profiles. Currently in Phase III development under the LILAC-TIMI 76 trial for stroke and systemic embolism prevention in atrial fibrillation, abelacimab is expected to reach study completion in the second half of 2026.

“Atrial flutter is often difficult to diagnose due to its intermittent presentation and symptom overlap with other arrhythmias. ECG showing classic sawtooth flutter waves, especially in inferior leads, is key, but distinguishing it from other supraventricular tachycardias may require prolonged monitoring. Accurate diagnosis is critical to avoid mismanagement.”

“Modern atrial flutter management balances rhythm and rate control, tailored to symptoms, comorbidities, and stroke risk. Catheter ablation offers durable rhythm control, while antiarrhythmic and anticoagulant drugs remain vital, particularly for non-candidates of invasive therapy. Personalized, patient-centered approaches and shared decision-making are key to optimal outcomes.”

“Key unmet needs in atrial flutter management include earlier detection to prevent complications, improved risk stratification to guide treatment choices, and better strategies for long-term anticoagulation. The overlap with atrial fibrillation adds complexity, underscoring the need for further research to refine care and improve outcomes.”
