Aortic Annuloplasty: Focus on the Use of an External Teflon Ring.

Aortic annuloplasty has been clearly demonstrated to have a protective influence in aortic valve repair. Over the past 20 years, different annuloplasty concepts have been proposed by different groups. However, the most appropriate approach to enable long-term annular stability remains highly controversial. The aim of this article is to give a general overview of all types of aortic annuloplasty, particularly focusing on the use of an external Teflon ring, as proposed by our group. In this technique, external root dissection is performed in the same fashion as for reimplantation; the only difference is that it is necessary to go below the coronary ostia take-off. A series of pledgeted sutures (usually between 6 and 9 sutures) are placed at the level of the virtual basal ring. The external ring is made using a Teflon strip with a length of 8 to 9 cm, to reduce the annulus to a diameter of between 21 and 23 mm. The sub-annular sutures are then passed at the appropriate level through the Teflon strip and the strip is parachuted outside the aortic root base, passing under the coronary ostia. The two ends of the Teflon strip are tied at the level of the non-coronary sinus. Aortic annuloplasty is a crucial step to improve valve competence and stabilization. While several techniques offer good mid- to long-term results, annuloplasty with an external Teflon ring appears to be a simple and effective alternative to guarantee stable root diameters. Longer follow-up studies are needed to confirm the mid- to long-term results.

Management of head and neck cancer in older patients.

OBJECTIVE: A progressive increase in the number of older patients with head and neck cancer has been observed in the last few years. The aim of this study was to assess our experience in the management of older patients with head and neck cancer (HNC) in comparison with younger patients. STUDY DESIGN: A retrospective review was conducted for all patients admitted and treated for newly diagnosed HNC between January 2008 and December 2012. The clinical characteristics, management approaches, and outcome data were recorded. RESULTS: In total, 316 patients with HNC (232 males, 84 females) were enrolled: 203 (64%) were in the young group, whereas 113 patients (36%) were in the older group. Comorbidities (P < .000005) and stage IV tumors (P < .0005) were more frequently observed in the older group. Treatment options were uniformly distributed within the 2 groups; only radiotherapy alone was more frequently administered in older patients (P < .0005). CONCLUSIONS: Chronologic age should not be a reason to deny appropriate treatments that could prevent death in older patients. A careful pretreatment assessment should always be performed.
