  1. Eight cases of ascending aortic mycotic pseudoaneurysm formed due to P. aeruginosa infection after HTX were found in the literature. All of them were male patients with a median age of 44 years. The median time between HTX and diagnosis was 5 month. Ventricular assist device related infection was common in medical history. Combined surgical and antibiotic treatment was performed, which however resulted in a recurrence rate of 43%. N/A: not available
