Florida sleeve is a safe and effective technique for valve salvage in acute stanford type A aortic dissection.

ABSTRACT

OBJECTIVE: Valve-sparing root replacement is commonly used for management of aortic root aneurysms in elective setting, but its technical complexity hinders its broader adoption for acute type-A aortic dissection (ATAAD). The Florida sleeve (FS) procedure is a simplified form of valve sparing aortic root reconstruction that does not require coronary reimplantation. Here, we present our outcomes of the FS repair in patients with dilated roots in the setting of an ATAAD. METHODS: We retrospectively reviewed 24 consecutive patients (2002-2018) treated with FS procedure for ATAAD. Demographic, operative, and postoperative outcomes were queried from our institutional database. Long term follow-up was obtained from clinic visits for local patients, and with telephone and telehealth measures otherwise. RESULTS: Mean age was 49 ± 14 years with 19 (79%) males. Marfan syndrome was present in 4 (16.7%) patients and 14 (58.3) had ≥2+ aortic insufficiency (AI). Nine (37.2%) had preoperative mal-perfusion or shock. The FS was combined with hemi-arch replacement in 15 (62.5%) patients and a zone-2 arch replacement in 9 (37.5%) patients. There were 2 (8.3%) early postoperative mortalities. Median follow-up period was 46 months (range, 0.3-146). The median survival of the entire cohort was 143.4 months. One patient (4.2%) required redo aortic valve replacement for unrelated aortic valve endocarditis at 30 months postoperatively. CONCLUSION: FS is simplified and reproducible valve-sparing root repair. In appropriate patients, it can be applied safely in acute Stanford type-A aortic dissection with excellent early and long-term results.
