Abstract
INTRODUCTION The treatment of complex aortic lesions involving the ascending, arch, and proximal descending aorta, remains challenging for surgeons despite the evolution of surgical techniques and aortic prostheses over decades. The frozen elephant trunk (FET) approach offers a one-stage repair of this entity of aortic pathologies. The main scope of this systematic review and meta-analysis is to evaluate the clinical outcomes and effectiveness of FET. EVIDENCE ACQUISITION In a systematic review, multiple electronic databases including EMBASE, Scopus, and PubMed/MEDLINE were searched from inception to June 2021 to identify relevant studies reporting on outcomes of total arch replacement (TAR) with FET. EVIDENCE SYNTHESIS Eighty-five studies met inclusion criteria, encompassing 10960 patients. Meta-analysis was conducted using the R-studio (RStudio, Boston, MA, USA) and STATA software (StataCorp LLC, College Station, TX, USA). The pooled in-hospital mortality rate was 7% (95% CI 0.05-0.09; I2=76%) and 12% for renal failure (95% CI 0.09-0.15; I2=88%), while the rates for paraplegia and cerebrovascular accidents were 3% (95% CI 0.02-0.04; I2=0%) and 6% (95% CI 0.05-0.08; I2=73%), respectively. Lower heterogeneity was attained after the stratification by the aortic pathologies, except for the renal failure. The distal anastomosis of the stent in zone 2 was significantly correlated with a lower renal failure development compared to zone 3 (odds ratio 0.52; 95% CI 0.33-0.82; P=0.069; I2=0%). CONCLUSIONS Our results indicate that the morbidities and mortality following TAR with FET were acceptable. We also associated the distal anastomosis in zone 2 with fewer renal failure development compared to that in zone 3.

Correlation of coagulopathy and frozen elephant trunk use in aortic arch surgery: A systematic review and meta-analysis. J Card Surg 2021; 36:4699-4714. [PMID: 34550616 DOI: 10.1111/jocs.16001] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Accepted: 09/14/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND The advent of frozen elephant trunk (FET) for reconstruction of elective and nonelective aortic arch surgery has augmented the treatment of complex aortic pathologies in a single-stage operation. To date, no studies have been focused on the prevalence and predictors of coagulopathy potentiated by FET procedure. METHODS In a systematic review, we searched databases up to June 2020 to find studies reporting coagulopathy complications after FET procedure. A proportional meta-analysis was carried out using STATA software (StataCorp). RESULTS A total of 46 studies consisting of 6313 patients were eligible. The pooled estimation of reoperation for postoperative bleeding was 7% (95% confidence interval [CI:] 5-8; I2 = 84.73%; reported by 39 studies including 4796 patients). The mean volume of transfused packed blood cells and fresh frozen plasma was 1677 ml (95% CI: 1066.4-2287.6) and 1016.5 ml (95% CI: 450.7-1582.3). The subgroup by the stent type showed a decrease in the heterogeneity (I2 = 0.01%, I2 = 53.95%, I2 = 0.01%, and I2 = 54.41% for Thoraflex® Hybrid, E-vita®, Frozenix®, and Cronus®, respectively). The subgroup by the chronicity of operation resulted in less heterogeneity among patients undergoing elective compared with nonelective operation (I2 = 29.22% vs. I2 = 80.56% in nonelective). Meta-regression analysis showed that age and male gender significantly impacted on the reoperation for postoperative bleeding. CONCLUSIONS The FET procedure for arch replacement is associated with coagulopathy complications and the transfusion of blood products. Male, age, and selective choice of FET use were found to be the heterogeneity sources of reoperation for postoperative bleeding.

Abstract
BACKGROUND The treatment of complex thoracic aorta pathologies remains a challenge for cardiovascular surgeons. After introducing Frozen Elephant Trunk (FET), a significant evolution of surgical techniques has been achieved. The present meta-analysis aimed to assess the efficacy of FET in acute type A aortic dissection (ATAAD) and the effect of circulatory arrest time on post-operative neurologic outcomes. METHODS A standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses search was conducted for all observational studies of patients diagnosed with ATAAD undergoing total arch replacement with FET reporting in-hospital mortality, bleeding, and neurological outcomes. A random-effect meta-analysis was performed using STATA software (StataCorp, TX, USA). RESULTS Thirty-five studies were eligible for the present meta-analysis, including 3211 patients with ATAAD who underwent total arch replacement with FET. The pooled estimate for in-hospital mortality, postoperative stroke, and spinal cord injury were 7% (95% CI 5 - 9; I2 = 68.65%), 5% (95% CI 4 - 7; I2 = 63.93%), and 3% (95% CI 2 - 4; I2 = 19.56%), respectively. Univariate meta-regression revealed that with increasing the duration of hypothermic circulatory arrest time, the effect sizes for postoperative stroke and SCI enhances. CONCLUSIONS It seems that employing the FET procedure for acute type A dissection is associated with acceptable neurologic outcomes and a similar mortality rate comparing with other aorta pathologies. Besides, increasing hypothermic circulation arrest time appears to be a significant predictor of adverse neurologic outcomes after FET.

Abstract
BACKGROUND The objective was to provide initial data from our prospective valve-sparing aortic root replacement (V-SARR) registry and reasons for conversion to prosthetic replacement (AVR). METHODS Six centers established an intention-to-treat-design V-SARR-registry (German Aortic Root Repair Registry, GEARR, first-patient-in 10/2016) with main inclusion criterion "scheduled for V-SARR as Plan A". Clinical information, operative details, intraoperative valve/root measurements and clinical/TTE follow-up-data are documented. RESULTS Of a total of n=449, we report data on n=401 patients (81% male, mean age 51±14y). N=350 underwent V-SARR as scheduled (Group A, "David"-variants I 55%, III 2%, IV 13%, V 24%, V- Stanford 2%, Yacoub-Remodeling 2%), n=51 were converted to AVR (Group B). Median follow-up was 11 months (0-2.6y), cumulative follow-up 279 patient-years. In Group B there were less connective tissue disorders (6vs16%), fewer patients had LVEF>50% (60%vs90%), more had bicuspid aortic valves (BAV,45%vs28%), fewer patients had preoperative non/trace AR (2%vs20%). Fewer individuals in Group B had rare types of BAV (fused N/L, R/N, 10%vs30%) and more had unbalanced roots (56%vs40%). Immediate-postoperative AR was none/trace in 79%, and mild in 20%. At 30 days the dpmean was 7±5mmHg. None of the patients died in hospital, two strokes occurred. One patient needed early AVR as re-do surgery. CONCLUSIONS Main factors causing surgeons to convert a planned V-SARR to AVR include asymmetry of aortic valve/root, severity of AR, safety-reasons (LVEF), and BAV, but not rare types of BAV. GEARR will help us identify the impact on long-term outcomes of pre- and postoperative valvular anatomy and various V-SARR types.

Abstract
BACKGROUND AND AIM OF THE STUDY The frozen elephant trunk (FET) procedure became a popular entity for utilization in aortic arch aneurysm disease. However, its proper mortality and morbidities as well as the predictors of outcomes are poorly identified. This systematic review and meta-analysis explore FET outcomes and its predictors with a focus on zone aortic proximalization. METHODS We searched PubMed/MEDLINE, EMBASE, and Scopus databases from their beginning to June 2020 to find studies reporting the outcomes of the FET procedure for the total arch replacement (TAR). RESULTS A total of 64 studies including 7967 patients were evaluated. The pooled estimates of cerebrovascular accidents, paraplegia, renal failure, and in-hospital mortality were 7.104 (95% confidence interval [CI], 5.691-8.661; I2 = 78.53%), 3.465 (95% CI, 2.852-4.136; I2 = 15.96), 14.969 (95% CI, 11.361-18.977; I2 = 91.26%), and 8.933 (95% CI, 7.128-10.919; I2 = 78.51%), respectively. Stratification by the geographical locations and by the aortic pathologies led to lower heterogeneity, but not for renal failure. The distal anastomosis in Zone 2 was associated with a lower rate of renal failure compared with Zone 3 (odds ratio, 0.54; 95% CI, 0.36-0.81; p = .003; I2 = 0%). CONCLUSIONS The FET procedure for TAR can be performed with acceptable mortality and morbidities among patients with complex aortic pathologies. Moreover, the distal anastomosis in Zone 2 was associated with lower renal failure compared to Zone 3.

Abstract
BACKGROUND We reported on a decade of aortic surgery for type A aortic dissection to assess surgical techniques employed and outcomes over time in an all-comer analysis of a mid-size university cardiosurgical center. METHODS From 2009 to 2018, 283 patients (189 males and 94 females, mean age 62 years, range 30-85 years), who underwent surgical therapy for type A aortic dissection in our institution were included in a retrospective statistical analysis. RESULTS Among all the patients, 55.5% of them were hemodynamically stable, 10.3% came in intubated. A neurological deficit was present in 18.9% of cases, extremity malperfusion was noted in 17.4%, and abdominal malperfusion detected in 8.2%. The extent of the aortic dissection corresponded to DeBakey type I in 88% of cases, a thoracoabdominal involvement was seen in 64%. In 51.9% of patients, only the ascending aorta replaced, another 40.6% of patients had proximal arch replacement too. A separate stent placement into the descending aorta was achieved in 13.4% of patients, during surgery (5.7%) or thereafter (7.7%). Overall survival to discharge was 79.5%. Most frequent complications were stroke and paralysis (15.2%), but only visceral malperfusion (OR 9.0) and heart failure mandating ECMO therapy (OR 29.5) were associated with significantly increased mortality. CONCLUSIONS Surgery for type A aortic dissection is still challenging. Along with the refinement of surgical techniques, the indication for the various procedures has moved from a simplified general strategy to a more individualized concept.

Abstract
OBJECTIVE Innumerable surgical techniques are currently deployed for repairing acute type A aortic dissection (ATAAD). We analyzed our results using a conservative approach of root-sparing and hemiarch techniques in higher-risk patients and root and total arch replacement for lower-risk patients. METHODS We queried our aortic database for consecutive patients who underwent ATAAD repair. Patients who underwent conservative repair (group 1) were compared with those who underwent extensive repair (group 2) using univariable and multivariable analysis. RESULTS From 1997 to 2019, 343 patients underwent ATAAD repair. Two hundred forty had conservative repair (root-sparing, hemiarch) whereas 103 had extensive repair (root replacement and/or total arch). Group 1 was older with more comorbidities such as hypertension, previous myocardial infarction, and renal dysfunction. Group 2 had more connective tissue disease (2.1% vs 12.6%; P < .01), aortic insufficiency, and longer intraoperative times. The incidence of individual postoperative complications was similar regardless of approach. A composite of major adverse events (operative mortality, myocardial infarction, stroke, dialysis, or tracheostomy) was higher in the conservative group (15.1% vs 5.9%; P = .03). Operative mortality was 5.6% and not different between groups. Ten-year survival was similar with either surgical approach. Ten-year cumulative risk of reintervention was greater in group 2 (5.6% vs 21% at 10 years; P < .01). In multivariable analysis, ejection fraction and diabetes were predictors of major adverse events but not extensive approach. Extensive approach was a predictor of late reoperation (odds ratio, 3.03 [95% confidence interval, 1.29-7.2]; P = .01). CONCLUSIONS A tailored conservative approach to ATAAD leads to favorable operative outcomes without compromising durability.
