INTRODUCTION: The QDOT MICROTM Ablation Catheter is a next-generation ablation catheter that allows for high-power ablation up to 90 watts.
METHODS: We aimed to assess AE associated with the QDOT MICROTM catheter using the MAUDE database. A MAUDE database search was conducted on May 25, 2024, to capture all AEs (since FDA approval) associated with this ablation catheter.
RESULTS: A total of 302 AEs from November 23, 2022, to April 30, 2024, were reported including 148 (49%) catheter-related issues and 154 (51%) clinical complications. Among the catheter-related issues, physical catheter damage (74.3%, n = 110) was most common, followed by communication or display issue (10.8%, n = 16), irrigation issue (9.5%, n = 14), signal issue or artifact (3.4%, n = 5), and inaccurate temperature measurement (2.0%, n = 3). Regarding clinical complications, the most common AE was pericardial effusion (43.5%, n = 67), followed by char formation (11.7%, n = 18), catheter thrombosis (7.1%, n = 11), stroke (7.1%, n = 11), pericarditis (7.1%, n = 11), esophageal complications (6.5%, n = 10), phrenic nerve palsy (3.9%, n = 6), cardiac arrest (3.9%, n = 6), significant AV block (3.9%, n = 6), pulmonary vein stenosis (3.2%, n = 5), coronary artery spasm (1.3%, n = 2), and pulmonary embolism (0.6%, n = 1). There were 11 deaths (five related to esophageal complications, five related to cardiac arrest, and one related to pericardial effusion with cardiac tamponade).
CONCLUSION: As high-power ablation strategy with novel ablation catheters is becoming more widely utilized, operators must be aware of potential catheter-related issues and clinical complications that may arise. More data are needed to further evaluate risks of these complications to improve the catheter's safety and efficacy.
