Use of FEops artificial intelligence enabled technology for preprocedural planning of left atrial appendage occlusion with Amulet Amplatzer device

Pre-procedural planning to guide structural heart interventions is often demanding and requires experience in cardiac imaging.Left atrial appendage (LAA) morphology is often complex [1] and variable.Transesophageal echocardiography (TEE) alone may not always be optimal to size the device adequately.Even experienced echocardiographers in certain conditions may sometimes have difficulty with proper sizing of the devices.Compared to TEE, computed tomography (CT) results in larger LAA orifice measurements, improves odds of predicting correct device size, and reduces fluoroscopy time in patients undergoing LAA occlusion [2].Application of 3D printing, computational modeling, and ultimately incorporation of artificial intelligence are changing the landscape of today's cardiac interventions [3].Here we present 5 cases of LAA occlusion with additional use of artificial intelligence (AI) enabled technology FEops performed in the First Department of Cardiology in Katowice. Case reports Case 1An 84-year-old man with persistent atrial fibrillation (CHA 2 DS 2 -VASc 6 points, HAS-BLED 4 points) was admitted for implantation of a left atrial occluder because of recurrent intestinal bleeding.Transthoracic echocardiography (TTE) revealed an enlarged left atrium with moderate valvular dysfunctions.In CT thrombus was excluded.Planning with FEops revealed a 2-lobed appendage with a very short but adequate landing zone (Figure 1).The AI simulated devices were the Amulet 22 mm, 25 mm, 28 mm, and 31 mm.
