OBJECTIVE: Minimally invasive valve surgery was first introduced into clinical practice during the mid 1990s; this technique is nowadays getting a growing diffusion especially because of the significant improvement in patients quality of life in the post-operative course. The more recent introduction of an intra-aortic balloon for aortic clamping is further facilitating this kind of surgery. In this case report we explain how to manage aortic balloon positioning in presence of a particular aortic configuration.
METHODS: From August 2012 to November 2015, 33 patients (20 male) underwent minimally invasive valve surgery with the use of IntraClude® (Edwards); mean age was 58±9,2 years. 22 were repair, 11 replacement, 2 redo surgeries. All these patients have been selected basing on the analysis of a pre-operative thoracic and abdominal CT scan performed to analyze aortic course and diameters. In three cases the radiological exam analysis detected some particular aspects: two patients had a bovine aortic arch associated to a very narrow curving at this level, while in the last case the aorta showed only a very close curving at the level of the arch. All these patients were young, with a wide aortic compliance and we experienced some problems at the moment of balloon positioning.
RESULTS: After femoro-femoral extra-corporeal circulation starting, under trans-esophageal control we began the Intraclude positioning by advancing the guide-but we didn’t succeed in visualizing it at the level of the ascending aorta because, due to the particular aortic arch configuration, the wire went straight into the supra-aortic vessels. At that moment we thought to use the kite effect: we inflated the balloon with 5 ml of saline solution and we advanced it alone without the wire taking advantage of the femoro-femoral flow directed towards the ascending aorta; this tip worked well and we could proceed with surgery.
CONCLUSIONS: Intra-aortic balloon for aortic clamping represent an important tool in minimally invasive valve surgery. In presence of a particular aortic configuration we can experience some problems but this shouldn’t be considered a reason for exclusion because thanks to some tricks it is possible to easily overcome the positioning difficulty.
