The mixed type of TAPVC is the most challenging type of TAPVC, in terms of timely diagnosis and management, being the least common type but also the type with the highest mortality. Over the years, contrast enhanced CT angiography has proven its superiority over echocardiography in accurate delineation of the complex pulmonary venous anatomy for guiding pre-surgical planning and thus improving the post-operative outcome. It also has the advantage of simultaneous assessment of the lung parenchyma and airway which plays a vital role in determining morbidity and mortality. We reviewed eight cases of mixed TAPVC diagnosed at our center between January 2021 to December 2024, all of whom underwent Echocardiography and CT angiography followed by complete surgical repair. 2 phase CT angiography was performed in all patients: phase 1- pulmonary phase (trigger placed on the main pulmonary artery), phase 2- cardiac phase- immediately obtained after phase 1 and extended down into the abdomen up to the lower margin of the liver to cover the infracardiac TAPVC variants. None of our patients needed Cardiac catheterization. We classified all 8 cases based on the systems proposed by Choudhury et al[1] as well as Xiang et al[2] to assess the reproducibility of these systems and their role in planning the surgical technique. Subsequently we analyzed this data with the cardiology and cardiothoracic surgery team to draw our own conclusions.
