Subpulmonary obstruction in transposition of the great arteries due to aneurysm of the membranous ventricular septum

[Robotic assistance systems for surgery : Current developments and focus of research]

As robotic systems are now technically mature and widely available, they also play an increasingly important role in the clinical environment. Thus, numerous robotic assistance systems for diagnosis and therapy have shown their potential for supporting patient care. After a brief review of the history, this article describes currently available robotic assistance systems for surgery, especially those originating in Germany and Europe as well as current focal topics of research. In addition, challenges in this field as well as possibilities for close active and interdisciplinary cooperation between stakeholders from hospitals, industry and science to overcome such challenges are presented.

How to report educational videos in robotic surgery: an international multidisciplinary consensus statement

The swift endorsement of the robotic surgical platform indicates that it might prevail as the preferred technique for many complex abdominal and pelvic operations. Nonetheless, use of the surgical robotic system introduces further layers of complexity into the operating theatre necessitating new training models. Instructive videos with relevant exposition could be optimal for early training in robotic surgery and the aim of this study was to develop consensus guidelines on how to report a robotic surgery video for educational purposes to achieve high quality educational video outputs that could enhance surgical training. A steering group prepared a Delphi survey of 46 statements, which was distributed and voted on utilising an electronic survey tool. The selection of committee members was designed to include representative surgical trainers worldwide across different specialties, including lower and upper gastrointestinal surgery, general surgery, gynaecology and urology. 36 consensus statements were approved and classified in seven categories: author’s information and video introduction, case presentation, demonstration of the surgical procedure, outcomes of the procedure, associated educational content, review of surgical videos quality and use of surgical videos in educational curricula. Consensus guidelines on how to report robotic surgery videos for educational purposes have been elaborated utilising Delphi methodology. We recommend that adherence to the guidelines presented could support advancing the educational quality of video outputs when designed for training.

Pseudoaneurysm of the membranous septum, case report and review of the literature

Pseudoaneurysm (dissecting aneurysm) of the membranous septum is a rare occasion. Clinically, aneurysms and pseudoaneurysms not only have the potential to reduce ventricular size, but also can be further complicated by rupture of the aneurysm and by promoting tricuspid insufficiency, aortic valve prolapse, ventricular outflow tract obstruction, and bacterial endocarditis. We describe a case in which a pseudoaneurysm of the membranous septum was identified protruding into the left outflow tract.

Late outcome after arterial switch operation for complete transposition of great arteries with left ventricular outflow tract obstruction

BACKGROUND

Long-term follow-up of patients who underwent arterial switch operation for complete transposition of great arteries with anatomic left ventricular outflow tract obstruction (LVOTO) has rarely been brought into the focus.

METHODS

Of 299 patients who underwent an arterial switch operation between January 1991 and January 2001, 23 patients had anatomic LVOTO. Age ranged from 4 days to 18 years (median 90 days) and weight ranged from 2.6 to 35 kg (median 4.3 kg). Surgical management included arterial switch operation, closure of ventricular septal defect wherever indicated, and excision of LVOTO.

RESULTS

Among patients with preoperative LVOTO there were 2 early deaths and 8 patients had mild neoaortic regurgitation at the time of discharge. Follow-up ranged from 8 months to 9 years (mean 60 +/- 12 months). In 4 patients who had mild neoaortic regurgitation at discharge, the regurgitation progressed to moderate or severe degree after a follow-up of 22 to 72 months. In 1 patient mild mitral regurgitation present at the time of discharge progressed to severe mitral regurgitation. This patient subsequently underwent double valve replacement.

CONCLUSIONS

Presence of preoperative anatomical LVOTO in patients undergoing arterial switch operation predicts high incidence of postoperative neoaortic regurgitation.
