Florida Sleeve Procedure Is Durable and Improves Aortic Valve Function in Marfan Syndrome Patients

Background The Florida sleeve (FS) procedure was developed as a simplified approach for repair of functional type I aortic insufficiency secondary to aortic root aneurysm. We evaluated postoperative aortic valve function, long-term survival, and freedom from reoperation in Marfan syndrome patients who underwent the FS procedure at our center. Methods All Marfan syndrome patients undergoing FS procedure from May 2002 to December 2014 were included. Echocardiography assessment included left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), ejection fraction, and degree of aortic insufficiency (none = 0, minimal = 1, mild = 2, moderate = 3, severe = 4). Social Security Death Index and primary care physicians’ report were used for long-term follow-up. Results Thirty-seven Marfan syndrome patients, 21 (56.8%) men and 16 (43%) women with mean age of 35.08 ± 13.45 years underwent FL repair at our center. There was no in-hospital or 30-day death or stroke. Two patients required reoperation due to bleeding. Patients’ survival rate was 94% at 1 to 8 years. Freedom from reoperation was 100% at 8 years. Twenty-five patients had postoperative follow-up echocardiography at 1 week. Aortic insufficiency grade significantly decreased after the procedure (preoperative mean ± SD: 1.76 ± 1.2 versus 1-week postoperative mean ± SD: 0.48 ± 0.71, p < 0.001), and mean LVEDD decreased from 52.23 ± 5.29 mm to 47.53 ± 8.89 mm ( p = 0.086). Changes in LVESD (35.33 ± 9.97 mm to 36.58 ± 9.82 mm, p = 0.58) and ejection fraction (57.65% ± 6.22% to 55% ± 10.83%, p = 0.31) were not significant. Conclusions The FS procedure can be performed safely in Marfan syndrome patients with immediate improvement in aortic valve function. Long-term survival and freedom from reoperation rates are encouraging.
