From 1985 to 1996, 18 patients with Marfan's syndrome underwent the Bentall procedure at Mount Sinai Hospital. They are compared with 38 patients aged < 40 without Marfan's syndrome who also underwent composite valve-graft replacement of the ascending aorta. The mean age of the non-Marfan group was 33 while that of the Marfan group was 29. ⋯ No difference in immediate operative mortality following the Bentall procedure was noted between patients with and without Marfan's syndrome, but young patients without Marfan's syndrome seem to have better event-free and long-term survival. In patients with Marfan's syndrome, the presence of acute dissection makes reoperation more likely, and sudden death from rupture still occurs despite careful postoperative surveillance. A higher incidence of severe mitral valve disease was found among young patients with Marfan syndrome than in controls.

Until recently the surgical treatment of aneurysms of the aortic root in patients with the Marfan syndrome consisted of composite replacement of the aortic valve and ascending aorta. At the present, almost one-half of these patients can have reconstruction of the aortic root with preservation of the aortic valve. The mitral valve can also be frequently preserved. ⋯ Although the number of patients in each group is small and the follow-up relatively short, aortic valve-sparing operations have given gratifying results and may prove superior to valve replacement in patients with the Marfan syndrome.

We currently routinely use profound hypothermic circulatory arrest (PHCA) with retrograde cerebral perfusion (RCP) during repair of proximal aortic dissection and aneurysms involving the transverse aortic arch. Experimental data regarding the efficacy of RCP are conflicting. We retrospectively reviewed our experience with proximal aortic surgery to compare the results of PHCA performed with and without RCP. ⋯ Patients who had RCP during PHCA had lower mortality and stroke rates than those who did not. Although the higher prevalence of cerebrovascular disease, diabetes, and dissection in the latter group may have contributed to these differences, the clinical results confirm the safety and potential benefits of RCP, further supporting its use during proximal aortic surgery requiring circulatory arrest.
