Restoration of the thoracic aorta in Type A dissection with hybrid prosthesis.
Following successful repair of Type A dissection, late morbidity and mortality depend on the progression of residual chronic Type B dissection. To avoid the development of late aneurysms of the descending thoracic aorta, a persistent aortic false lumen around the stent-graft can be prevented by remodeling the thoracic aorta. Ten consecutive patients (mean age: 56 years) with acute Type A dissection underwent a "frozen elephant trunk operation" with the E-vita hybrid prosthesis, under deep hypothermic circulatory arrest, between October 2009 and April 2010. ⋯ Two patients suffered postoperative pulmonary arterial embolism; one underwent embolectomy. Restoration of the thoracic aorta is a safe procedure to close the false lumen during the primary operation for acute Type A dissection. However, the diameter of the stent should reflect the overall aortic size, independent of the diameter of the true lumen.

Case ReportsTricuspid valve repair in Ebstein's anomaly by posterior annular plication.
Two girls, aged 14 and 11 years, with Ebstein's anomaly, were treated by simple posterior annular plication of the functional annulus, without plication of the atrialized right ventricle. At follow-up after 15 and 12 months, both patients were in functional class I with no tricuspid regurgitation on echocardiography. This technique looks simple, safe, and effective, particularly for mild forms of Ebstein's anomaly, but the longevity of this repair remains to be determined.
