Objective: The aim of this study was to report 10-year real-world single-center experience with the GORE TAG conformable thoracic aortic graft (CTAG), focusing on rupture-free survival, aortic-related reintervention, and device-related complications during midterm and long-term follow-up (FU). Methods: This retrospective study analyzes results of thoracic endovascular aortic repair (TEVAR) performed between January 2009 and December 2018. Out of 419 TEVAR procedures within this period, 194 patients (male 57.2%, 111/194), with a mean age of 65 ± 13 years, were treated with the CTAG device. Indication for TEVAR was a thoracic aortic aneurysm in 24.7% (48/194), type B aortic dissection in 32.5% (63/194), penetrating aortic ulcer 15.5% (30/194), and miscellaneous 27.3% (53/194). Emergently were operated 43.8% (85/194) patients. Median follow-up (FU) including computed tomography imaging was 43.5 months (Q1-Q3: 8.6–67.0) and was completed in 91.2% (177/194) of patients. Results: Overall survival rates were 75.8% (95% confidence interval [CI] = [0.76–0.70]) and 56.6% (95% CI = [0.57–0.50]) at 12 and 60 months, respectively. Cumulative incidence for aortic rupture was 11.9% (95% CI = [0.07–0.17]) at 60 and 90 months, respectively. Cumulative incidence for aortic-related reintervention was 27.5% (95% CI = [0.21–0.34]) at 60 and 90 months. Cumulative incidence for migration was 2.8% (95% CI = [0.004–0.05]) and 3.9% (95% CI = [0.007–0.07]) at 60 and 90 months, respectively. New endograft infections or material fatigue were not observed. Conclusions: The herein reported 10-year real-world single-center experience with the CTAG observed favorable long-term outcome. Thus, the device demonstrates appropriate persistent safety, efficacy, and clinical durability up to long-term FU in the treatment of diverse thoracic aortic pathologies.

OBJECTIVEPrevious reports have addressed the short-term response of patients with Chiari-related scoliosis (CRS) to suboccipital decompression and duraplasty (SODD); however, the long-term behavior of the curve has not been well defined. The authors undertook a longitudinal study of a cohort of patients who underwent SODD for CRS to determine whether there are factors related to Chiari malformation (CM) that predict long-term scoliotic curve behavior and need for deformity correction.METHODSThe authors retrospectively reviewed cases in which patients underwent SODD for CRS during a 14-year period at a single center. Clinical (age, sex, and associated disorders/syndromes) and radiographic (CM type, tonsillar descent, pBC2 line, clival-axial angle [CXA], syrinx length and level, and initial Cobb angle) information was evaluated to identify associations with the primary outcome: delayed thoracolumbar fusion for progressive scoliosis.RESULTSTwenty-eight patients were identified, but 4 were lost to follow-up and 1 underwent fusion within a year. Among the remaining 23 patients, 11 required fusion surgery at an average of 88.3 ± 15.4 months after SODD, including 7 (30%) who needed fusion more than 5 years after SODD. On univariate analysis, a lower CXA (131.5° ± 4.8° vs 146.5° ± 4.6°, p = 0.034), pBC2 > 9 mm (64% vs 25%, p = 0.06), and higher initial Cobb angle (35.1° ± 3.6° vs 22.8° ± 4.0°, p = 0.035) were associated with the need for thoracolumbar fusion. Multivariable modeling revealed that lower CXA was independently associated with a need for delayed thoracolumbar fusion (OR 1.12, p = 0.0128).CONCLUSIONSThis investigation demonstrates the long-term outcome and natural history of CRS after SODD. The durability of the effect of SODD on CRS and curve behavior is poor, with late curve progression occurring in 30% of patients. Factors associated with CRS progression include an initial pBC2 > 9 mm, lower CXA, and higher Cobb angle. Lower CXA was an independent predictor of delayed thoracolumbar fusion. Further study is necessary on a larger cohort of patients to fully elucidate this relationship.

Abstract Background Posterior location of a paravalvular leak (PVL) affects left ventricle fluid dynamics in a more unfavorable way than leaks of the other locations. Purpose To assess impact of the PVL location and its grade on subsequent long term mortality after successful TAVR. Methods Out of 445 consecutive patients treated between 8/2009 and 10/2017 within the single-center, prospective TAVR Registry, there were 432 pts [median 83.0 years of age, 63.4% female] with device success (97.1%) as per VARC-2. Post-procedural TTE studies done within 7 days post-TAVR were analyzed for PVL location (anterior vs posterior vs medial vs lateral) and grade (none/trace/mild vs moderate). Long-term mortality was assessed. Results Median follow-up was 29.3 (15.8–53.1) months with 1-year follow-up in all pts. The 30-day and 1-year mortality rates were 3.0% (n=13) and 13.4% (n=58) with an estimated 4-year mortality of 35.5%. Moderate PVL was reported in 28.5% (n=123) of pts, with 12.0% (n=52) having multiple locations (>1 PVL). Among moderate PVLs (n=184), most were of anterior (33.2%), 29.3% were posterior, 25.2% were lateral, and the least common location was medial (12.0%). Whereas moderate PVL alone was not associated with worse long-term outcome, the 1-year mortality rates tended to be higher for pts with PVL found at multiple or posterior locations (19.2% vs 12.6% among the rest of the subjects, p=0.20, and 18.5% vs 12.7%, p=0.28, respectively). The KM curves suggest mid-term clinical importance of multiple or posterior PVLs (Fig 1A and 1B). Figure 1 Conclusions Moderate PVL found in multiple locations or recognized in the posterior location tend to be associated with worse midterm (1–2 years) prognosis after successful TAVR.
