Abstract: A basilica system for use in replacement heart valve implant procedures may include a first catheter including a side port disposed proximal of a distal tip, a conductive guidewire slidably disposed within the first catheter and configured to be advanced out the side port proximate a leaflet of a replacement heart valve implant disposed within a native heart valve of a patient, a second catheter including a lumen extending to a distal end of the second catheter, and a snare shaft slidably disposed within the second catheter, the snare shaft including a wire loop configured to grasp the conductive guidewire. The basilica system may include a delivery catheter. The first and second catheters may be disposed within the delivery catheter. The conductive guidewire may be configured to be electrically coupled to a source of RF energy. The conductive guidewire may be configured to puncture the leaflet.
