  Figure 1. Computed Tomography Pulmonary Angiogram Computed tomography pulmonary angiogram demonstrating dissection of the RPA connected by a narrow neck (black arrow) to a cavity (blue arrow), measuring about 14 × 26 mm in the transverse plane, and situated between the upper part of the LA and the aortic root. This cavity in turn connects by a narrow neck (white arrow) to the LA. There is right to left shunting across this RPA-to-LA fistula. LA = left atrium; RPA = right pulmonary artery.
