An 83-year-old morbid woman presented with severe dyspnoea (New York Heart Association [NYHA] Class IV) and a history of recurrent pulmonary oedema. Due to an acute type A aortic dissection, she had previously undergone aortic surgery (January 2009), which included the implantation of an ascending aortic prosthesis.

On admission, transthoracic echocardiography revealed severe pulmonary hypertension with an estimated systolic pulmonary pressure of 70-75 mmHg and severe tricuspid regurgitation. Using 3D transoesophageal echocardiography (Figure 1A, Moving image 1-3) and computed tomography (Figure 1B), a rupture of the aortic prosthesis with a fistula from the paraprosthetic lumen to the right pulmonary artery (Figure 1A, Figure 1B, Online Figure 1, Moving image 1-3) was found.

B) Fistula visualised by computed tomography. C) Post-interventional computed tomography showing the correct position of the ASD occluder.

Because of multiple concomitant diseases and severe right-sided heart failure, an interventional approach was initiated. With a complex 3D echo-guided intervention (Online Figure 2, Moving image 4), the fistula was successfully closed using a 12 mm AMPLATZER™ ASD occluder (St. Jude Medical, St. Paul, MN, USA), which resulted in an immediate reduction in shunt volume. Post-interventional imaging showed the correct position of the ASD occluder with only minor residual flow (Online Figure 3, Moving image 5-7).

At 18-month follow-up CT (Figure 1C), the patient presented with surprising improvement of the pre-existing dyspnoea, from NYHA Class IV to NYHA Class II. The echocardiographic calculation showed a reduction in estimated systolic pulmonary pressure to 45-50 mmHg.
