Physicians' Perspective on Percutaneous Left Atrial Appendage Closure in Patients with Atrial Fibrillation and...

This study, conducted in Pakistan, examines the perspectives of 1200 physicians across diverse specialties regarding Left Atrial Appendage Occlusion (LAAO) procedures for atrial fibrillation (AF) patients with chronic kidney disease (CKD). Using a random sampling approach, physicians participated in a survey that assessed their familiarity with LAAO, views on its effectiveness and safety, experience levels, and encountered challenges. The results unveil a spectrum of knowledge levels among physicians, reinforcing the need for tailored medical education and training programs. The majority of respondents were between 30 and 49 years old (59.8 %). A notable proportion, 33.3 %, had limited or no knowledge of LAAO, with 16.7 % having never heard of the procedure, and 16.7 % having limited knowledge but no experience. About 36.2 % of physicians believed LAAO was moderately to extremely effective in reducing stroke risk, with 23.3 % considering it very effective and 25.4 % believing it to be extremely effective. The most commonly cited clinical indications were a history of recurrent strokes despite anticoagulation (34.6 %) and a high CHA2DS2-VASc score (27.3 %). Renal considerations played a significant role, with 33.1 % considering LAAO for CKD stage 4 or 5 patients with elevated stroke risk. Patient preferences, such as a desire to avoid long-term anticoagulant use, were important for 28.7 % of physicians. Identified challenges encompass limited equipment access, training gaps, patient reluctance, and administrative complexities. Furthermore, the study underscores the pivotal role of shared decision-making in healthcare delivery. These findings lay essential groundwork for improving LAAO utilization and patient-centered care in Pakistan's healthcare system.
