Multistage Endovascular Management of a Thoracoabdominal Aortic Aneurysm in a Post–Heart Transplant Patient

The development of aneurysms of thoracoabdominal aorta (TAAA) in a post-transplant patient is a rare clinical situation and requires special attention. Endovascular treatment is the most suitable option for these patients due to numerous comorbidities. Particular emphasis should be placed on the ejection fraction as one of the main criteria for qualifying for surgery. The treatment itself remains a major challenge relating to anatomical constrains; however, it is possible in select patients in experienced centers.

Atrioventricular synchronous pacing using leadless pacemaker in a heart transplant patient

We report the first leadless pacemaker (L-PM) providing atrioventricular synchronous pacing implanted into a heart transplant patient receiving chronic immunosuppressive therapy. The patient presented with syncope corresponding to sinus rhythm with high-grade atrioventricular block. Previously, L-PMs provided only single-chamber ventricular sensing and pacing. A Micra AV lL-PM provides atrioventricular synchronous pacing by tracking mechanical atrial contraction. L-PMs, which now support broader indications, should be considered in patients at greater risk of infection.
