LEFT VENTRICULAR PSEUDOANEURYSM: PLANNING A SURGICAL CORRECTION WITH VIRTUAL CT HEART NAVIGATION

Left ventricular (LV) pseudoaneurysm is a rare and fatal complication of myocardial infarction that needs promptly surgical management. In the last years, 3D visualization of cardiac anatomy has reached high levels of detail for surgical planning, aiding surgeon to perform faster, sharper and more efficient operations. The case we present is an example of how powerful CT scan evaluation can be in the hand of a cardiac surgeon while planning a challenging procedure such as closing a wide tear at the base of the LV. In our video, direct 3D-heart-navigation is provided by a dedicated software (Acquarius I-intuition) where complex anatomical features are analyzed. The type of ventricular access, materials and patch dimension, spatial orientation of the patch itself to maintain LV chamber geometry and its anchoring suture lines are chosen based on CT images. The operation is then summarized throughout multiple intraventricular shots depicting the most important surgical steps.
