Long-term results of endovascular aortic repair for thoracic pseudoaneurysms after previous surgical coarctation repair.
Late aneurysm formation has been reported after every type of surgical coarctation repair in up to 10%, with rupture of such aneurysms being responsible for approximately 7% of all deaths. Secondary surgical repair carries a significant mortality (up to 15%) and morbidity rate (recurrent laryngeal nerve paralysis ∼20%, phrenic nerve injury ∼5%). According to the positive experience with endovascular therapy of atherosclerotic thoracic aortic aneurysms, it is worthwhile to evaluate the concept of minimally invasive endovascular stent grafting for secondary repair of postsurgical aneurysms. ⋯ According to the current limited experience of small series, the endoluminal repair seems to be a promising alternative to redo open operations for postsurgical thoracic aneurysms associated with coarctation repair. Long-term follow-up of our small cohort confirmed the durability of the stent-graft treatment.

ReviewHow does successful bridging with ventricular assist device affect cardiac transplantation outcome?
A best evidence topic in cardiac surgery was written according to a structured protocol. The issue was to determine the impact of bridge-to-transplant ventricular assist device support on survival after cardiac transplantation. Altogether 428 papers were found using the reported search, of which 12 represented the best evidence to answer the clinical question. ⋯ In papers reporting a difference in outcome, one year averaged survival was 74% in LVAD recipients compared to 90% in non-bridged patients. Decreased survival is associated with patients suffering from dilated cardiomyopathy, transplanted within two weeks of LVAD implantation and bridged to transplantation before 2003 as opposed to patients transplanted more recently. Based on the available evidence we conclude that in selected patients survival after heart transplantation in patients bridged with VAD is comparable to those who did not receive the device.

Case ReportsOne-stage total thoracic aortic repair for mega-aorta using frozen elephant trunk technique.
We report the case of a 71-year-old female with mega-aorta extending from the ascending aorta to the descending aorta, who was successfully treated with a one-stage total thoracic aortic repair by the frozen elephant trunk technique using a stent-graft. We used a home-made frozen elephant trunk with four giant-turco Z-stents on the distal side that was inserted into the downstream descending aorta via an aortic arch guiding pull-through wire. ⋯ A postoperative computed tomography scan demonstrated complete thrombosis of the descending thoracic aneurysm without endoleak. In conclusion, the frozen elephant trunk was effective as a one-stage operation for mega-aorta.

Long-term outcome following repair of acute type A aortic dissection after previous cardiac surgery.
We evaluated the outcome after repair for acute spontaneous type A aortic dissection in patients with previous cardiac surgery. From January 2000 to December 2009, 114 patients underwent emergency repair for acute spontaneous type A dissection at Southampton University Hospital. Eleven (median age 64 years; range 36-83 years; two females) patients (9.8%) had undergone previous cardiac surgery and were included in this study. ⋯ Median length of hospital stay was 16 days (range 6-34 days). Actuarial survival at five and eight years for redo compared to first-time surgery was 68±3.63% vs. 81±5.34% and 51±3.8% vs. 61±5.4%, respectively (P=0.365). In conclusion, acute type A aortic dissection repair in patients with previous cardiac surgery has an acceptable mortality and comparable long-term outcome to first-time surgery.

Case ReportsNeonatal repair of right interrupted aortic arch with cerebro-myocardial perfusion technique.
Right interrupted aortic arch and descending aorta is exceedingly rare and most likely cause respiratory presentation, since patent ductus arteriosus (PDA) courses over the right mainstem bronchus. We report a case of successful neonatal biventricular repair of a right interrupted aortic arch (type B), with an aberrant right subclavian artery ventricular septal defect (VSD) in a 2.7 kg term neonate with DiGeorge syndrome. Patient presented in severe respiratory distress and acidosis at one day old. ⋯ A direct tension-free anastomosis was attained. Her postoperative course was uneventful and her respiratory symptoms disappeared postoperatively. Early surgical correction is mandatory for these patients with unique anatomy and presentation.
