“…Significant aortic annular dilatation requiring annular fixation is a contraindication for these approaches. Another indication is supravalvular stenosis, which can be congenital or acquired, and the repair option of this pathology depends on its involvement: single [46], double [47], or triple [48] sinus replacement. Isolated sinusal involvement usually affects NCS, especially in a bicuspid aortic valve.…”

The aortic root has a complex anatomy due to a combination of several anatomical structures based on simple and consistent work in it. It is a hollow cylinder with three bulges, which have the main functional effect on the aortic valve opening-closing cycle and coronary circulation. Aneurysm is defined as a dilation of a blood vessel segment having ≥50% increase in diameter, whereas annuloaortic ectasia represents a diffuse dilation <50% of the normal diameter of the related vessel segment. Aortic root aneurysms mostly occur by degenerative processes as compared with primarily atherosclerotic changes in the descending and abdominal aortas: medial fragmentation, smooth muscle cells necrosis, and elastic fiber fragmentations with cystic spaces in the media filled with mucoid material. Because of the elevated mortality risk associated with complications, an effective aortic root aneurysm management depends on reduction the risk of death, rupture, and dissection. Conventional open heart surgery is the essential procedure for isolated aortic root replacement and a type of procedure (valve replacement or sparing) could be selected due to the pathology. An extensive aortic root replacement technique is the only option to rebuild the left ventricular outflow tract due to the reconstruction of the neo aortoventricular continuity in the aortic root abscess.

“…Thus, temporary pacing wires are routinely inserted in the right atrium (RA) and right ventricle (RV) after successful implantation of the donor’s heart. Furthermore, intermittent temporal pacing can facilitate the patients’ weaning process from cardiopulmonary bypass [ 2 ]. During the postoperative course, these wires are intended to be completely removed.…”

Background Temporary epicardial pacing wires, implemented in patients during heart transplantation, are routinely removed before discharge. However, in some cases, these wires may remain in situ and are often considered as a contraindication for cardiovascular magnetic resonance (CMR) imaging in the future. Therefore, we aimed to provide data about safety and image quality of CMR in these patients. Methods This is a report on a subpopulation out of 88 patients after heart transplantation that were included in a prospective cohort study and underwent multiple CMR in their post-transplant course. During CMR, patients were monitored by electrocardiogram and all examinations were observed by a physician to document potential adverse events. Additionally, image quality was assessed by an imaging specialist. Results Nineteen of 88 patients included had temporary pacing wires in situ. These patients underwent a total of 51 CMR studies. No major adverse event and only one single, mild sensory event could be documented. All CMR studies showed preserved diagnostic image quality. Temporary pacing wires were visible in 100% of HASTE and cine sequences. In less than 50% of the examinations, temporary pacing wires were also visible in T1 and T2 mapping, short tau inversion recovery (STIR), and late gadolinium enhancement (LGE) sequences, without any impairment of image quality. Conclusions With a low event rate of only one mild adverse event during 51 CMR examinations (2%), CMR appears to be safe in patients with retained temporary epicardial pacing wires after heart transplantation. Moreover, image quality was not impaired by the presence of pacing wires.
