While these prosthetic valves have a lower thrombogenic profile than mechanical heart valves, leaflet thrombosis in transcatheter aortic valves (TAV) occurs in an estimated 5%-40% of cases. Most TAV thromboses are subclinical and can be detected via cardiac computed tomography (CCT), which reveals hypo-attenuating leaflet thickening and reduced leaflet motion in asymptomatic patients without elevated transprosthetic gradients on echocardiography. The mechanisms behind TAV thrombosis involve local mechanical triggers, patient predisposing factors, and device and procedure-related aspects. The ideal antithrombotic therapy post-TAVR depends on individual patient characteristics, balancing bleeding risks with the need for oral anticoagulants. Data on the optimal management of TAV thrombosis and the routine use of CT post-TAVR are limited. While anticoagulation effectively resolves clinically significant prosthesis thrombosis, its benefit in subclinical cases is unclear. There is an ongoing debate about whether subclinical leaflet thrombosis precedes clinical valve thrombosis, making the ideal follow-up after valve implantation uncertain.

This review outlines the recommended catheter manipulations based on the site of ectopic coronary origin. Identifying the initial course (prepulmonic, subpulmonic, interarterial or retroaortic course) is crucial for classifying each AAOCA. Besides invasive coronary angiography, coronary computed tomography angiography is frequently utilized to enhance the diagnostic assessment. Cardiac catheterization enables the use of intracoronary imaging and physiologic tools for accurately assessing the significance of AAOCA identified as at risk, mainly the anomalies associated with an interarterial course. Intravascular ultrasound is recognized as the gold standard for analyzing AAOCA with interarterial course. Optical tomography coherence imaging can be interesting to evaluate the rare AAOCA with a subpulmonic course, which are associated with ischemic symptoms or myocardial ischemia.
