Left Atrial Appendage Closure Device Market Report 2025

This report covers market characteristics, size and growth, segmentation, regional and country breakdowns, competitive landscape, market shares, trends and strategies for this market. It traces the market’s historic and forecast market growth by geography.

The left atrial appendage closure device market size has grown rapidly in recent years. It will grow from $1.67 billion in 2024 to $2 billion in 2025 at a compound annual growth rate (CAGR) of 19.5%. The growth in the historic period can be attributed to prevalence of atrial fibrillation, stroke prevention strategies, clinical evidence and research, minimally invasive alternatives, patient preference for non-pharmacological options, aging population, physician training and expertise.

The left atrial appendage closure device market size is expected to see rapid growth in the next few years. It will grow to $3.74 billion in 2029 at a compound annual growth rate (CAGR) of 17%. The growth in the forecast period can be attributed to rising global burden of atrial fibrillation, focus on stroke prevention in high-risk patients, expanding patient awareness, integration into standard clinical practice, global efforts in cardiovascular disease management. Major trends in the forecast period include emergence of percutaneous closure techniques, advancements in device designs, increasing use of imaging technologies, focus on minimally invasive approaches, tailored device selection for patient anatomy.

The increasing prevalence of atrial fibrillation is anticipated to drive the growth of the left atrial appendage (LAA) closure device market in the foreseeable future. Atrial fibrillation is a medical condition characterized by an irregular and often rapid heartbeat, resulting from the heart's upper chambers, known as the atria, not beating in a coordinated and rhythmic manner. Left atrial appendage (LAA) closure devices play a crucial role in treating atrial fibrillation by reducing the risk of stroke in patients with this cardiac arrhythmia and preventing the formation or escape of blood clots. As reported in October 2022 by the Centers for Disease Control and Prevention, a US-based government agency, atrial fibrillation was the predominant diagnosis in over 454,000 hospital admissions annually in the US. Projections suggest that by the year 2030, approximately 12.1 million people in the US are expected to have atrial fibrillation. Thus, the escalating prevalence of atrial fibrillation is poised to act as a catalyst for the growth of the left atrial appendage (LAA) closure device market.

The growth of the geriatric population is also anticipated to contribute to the expansion of the LAA closure device market. The geriatric population, consisting of individuals aged 65 and older, has distinct healthcare needs and faces challenges associated with aging. LAA closure devices prove beneficial for the geriatric population by reducing the risk of stroke linked to atrial fibrillation, which is a prevalent condition among older adults. As of August 2023, Eurostat, a Europe-based government agency, reported that over 21% of the EU population was aged 65 and above in 2022, with a median age reaching 44.4 years. This indicates that more than half of the population was older than this median age. Consequently, the growing geriatric population is playing a significant role in propelling the growth of the left atrial appendage (LAA) closure device market.

Major companies in the left atrial appendage closure device market are focusing on developing innovative products, such as the Watchman FLX, to advance the treatment of non-valvular atrial fibrillation (NVAF) and provide patients with an alternative to oral anticoagulation therapy. The Watchman FLX pro device, a self-expandable device implanted in the LAA, blocks the opening and prevents the formation of blood clots. For instance, in September 2022, Boston Scientific Corporation received approval from the Food and Drug Administration for Watchman FLX, designed to reduce the risk of stroke in individuals with NVAF. It is more flexible and accessible for implantation compared to previous versions, catering to a broader range of patients. It serves as a safe and effective option for those not eligible for oral anticoagulation therapy or facing challenges in managing such therapy.

In February 2022, Boston Scientific Corporation, a US-based medical device manufacturing company, acquired Baylis Medical Company, Inc. for $1.75 billion. Through this acquisition, Boston Scientific aims to bolster its position in the cardiology market, becoming the sole company with a comprehensive access portfolio paired with existing left-heart therapies such as left atrial appendage closure and atrial fibrillation ablation. Baylis Medical Company Inc., based in Canada, specializes in developing and manufacturing transseptal access solutions used to access the left atrium of the heart for procedures such as left atrial appendage closure.

A left atrial appendage closure device is a medical implant employed in the treatment of specific heart conditions, particularly in patients with atrial fibrillation (AF). These devices are surgically implanted in a minimally invasive procedure to mitigate the risk of stroke in AF patients. The primary mechanism involves sealing off or occluding the left atrial appendage (LAA), thereby preventing the entry and clotting of blood.

The two main categories of products within left atrial appendage closure devices are epicardial left atrial appendage (LAA) devices and endocardial left atrial appendage (LAA) devices. Epicardial left atrial appendage (LAA) devices encompass medical devices and techniques utilized for the closure or exclusion of the left atrial appendage from the exterior of the heart. This category includes both percutaneous and surgical procedures, with various end-users such as hospitals, ambulatory surgical centers, and other medical facilities.
