RESUMO
BACKGROUND: The benefits and harms associated with femoral artery cannulation over other sites of arterial cannulation for surgical repair of acute Stanford type A aortic dissection (TAAD) are not conclusively established. METHODS: We evaluated the outcomes after surgery for TAAD using femoral artery cannulation, supra-aortic arterial cannulation (i.e., innominate/subclavian/axillary artery cannulation), and direct aortic cannulation. RESULTS: 3751 (96.1%) patients were eligible for this analysis. In-hospital mortality using supra-aortic arterial cannulation was comparable to femoral artery cannulation (17.8% vs. 18.4%; adjusted OR 0.846, 95% CI 0.799-1.202). This finding was confirmed in 1028 propensity score-matched pairs of patients with supra-aortic arterial cannulation or femoral artery cannulation (17.5% vs. 17.0%, p = 0.770). In-hospital mortality after direct aortic cannulation was lower compared to femoral artery cannulation (14.0% vs. 18.4%, adjusted OR 0.703, 95% CI 0.529-0.934). Among 583 propensity score-matched pairs of patients, direct aortic cannulation was associated with lower rates of in-hospital mortality (13.4% vs. 19.6%, p = 0.004) compared to femoral artery cannulation. Switching of the primary site of arterial cannulation was associated with increased rate of in-hospital mortality (36.5% vs. 17.0%; adjusted OR 2.730, 95% CI 1.564-4.765). Ten-year mortality was similar in the study cohorts. CONCLUSIONS: In this study, the outcomes of surgery for TAAD using femoral arterial cannulation were comparable to those using supra-aortic arterial cannulation. However, femoral arterial cannulation was associated with higher in-hospital mortality than direct aortic cannulation. TRIAL REGISTRATION: ClinicalTrials.gov registration code: NCT04831073.

OBJECTIVE: The aim of this study was to evaluate the outcomes of different surgical strategies for acute Stanford type A aortic dissection (TAAD). SUMMARY BACKGROUND DATA: The optimal extent of aortic resection during surgery for acute TAAD is controversial. METHODS: This is a multicenter, retrospective cohort study of patients who underwent surgery for acute TAAD at 18 European hospitals. RESULTS: Out of 3902 consecutive patients, 689 (17.7%) died during the index hospitalization. Among 2855 patients who survived 3 months after surgery, 10-year observed survival was 65.3%, while country-adjusted, age-adjusted, and sex-adjusted expected survival was 81.3%, yielding a relative survival of 80.4%. Among 558 propensity score-matched pairs, total aortic arch replacement increased the risk of in-hospital (21.0% vs. 14.9%, P =0.008) and 10-year mortality (47.1% vs. 40.1%, P =0.001), without decreasing the incidence of distal aortic reoperation (10-year: 8.9% vs. 7.4%, P =0.690) compared with ascending aortic replacement. Among 933 propensity score-matched pairs, in-hospital mortality (18.5% vs. 18.0%, P =0.765), late mortality (at 10-year: 44.6% vs. 41.9%, P =0.824), and cumulative incidence of proximal aortic reoperation (at 10-year: 4.4% vs. 5.9%, P =0.190) after aortic root replacement was comparable to supracoronary aortic replacement. CONCLUSIONS: Replacement of the aortic root and aortic arch did not decrease the risk of aortic reoperation in patients with TAAD and should be performed only in the presence of local aortic injury or aneurysm. The relative survival of TAAD patients is poor and suggests that the causes underlying aortic dissection may also impact late mortality despite surgical repair of the dissected aorta.

AIMS: In this study we evaluated the impact of direct aortic cannulation versus innominate/subclavian/axillary artery cannulation on the outcome after surgery for type A aortic dissection. METHODS: The outcomes of patients included in a multicenter European registry (ERTAAD) who underwent surgery for acute type A aortic dissection with direct aortic cannulation versus those with innominate/subclavian/axillary artery cannulation, i.e. supra-aortic arterial cannulation, were compared using propensity score matched analysis. RESULTS: Out of 3902 consecutive patients included in the registry, 2478 (63.5%) patients were eligible for this analysis. Direct aortic cannulation was performed in 627 (25.3%) patients, while supra-aortic arterial cannulation in 1851 (74.7%) patients. Propensity score matching yielded 614 pairs of patients. Among them, patients who underwent surgery for TAAD with direct aortic cannulation had significantly decreased in-hospital mortality (12.7% vs. 18.1%, p = 0.009) compared to those who had supra-aortic arterial cannulation. Furthermore, direct aortic cannulation was associated with decreased postoperative rates of paraparesis/paraplegia (2.0 vs. 6.0%, p < 0.0001), mesenteric ischemia (1.8 vs. 5.1%, p = 0.002), sepsis (7.0 vs. 14.2%, p < 0.0001), heart failure (11.2 vs. 15.2%, p = 0.043), and major lower limb amputation (0 vs. 1.0%, p = 0.031). Direct aortic cannulation showed a trend toward decreased risk of postoperative dialysis (10.1 vs. 13.7%, p = 0.051). CONCLUSIONS: This multicenter cohort study showed that direct aortic cannulation compared to supra-aortic arterial cannulation is associated with a significant reduction of the risk of in-hospital mortality after surgery for acute type A aortic dissection.

OBJECTIVE: There is a paucity of sex-specific data on patients' postcardiotomy venoarterial extracorporeal membrane oxygenation (VA-ECMO). The present study sought to assess this issue in a multicenter study. DESIGN: Retrospective, propensity score-matched analysis of an international registry. SETTING: Multicenter study, tertiary university hospitals. PARTICIPANTS: Data on adult patients undergoing postcardiotomy VA-ECMO. MEASUREMENTS AND MAIN RESULTS: Between January 2010 and March 2018, patients treated with postcardiotomy VA-ECMO at 17 cardiac surgery centers were analyzed. Index procedures considered were coronary artery bypass graft surgery, isolated valve surgery, their combination, and proximal aortic root surgery. Hospital and five-year mortality constituted the endpoints of interest. Propensity score matching was adopted with logistic regression. A total of 358 patients (mean age: 63.3 ± 12.3 years; 29.6% female) were identified. Among 94 propensity score-matched pairs, women had a higher hospital mortality (70.5% v 56.4%, p = 0.049) compared with men. Logistic regression analysis showed that women (odds ratio [OR], 1.87; 95% confidence interval [CI] 1.10-3.16), age (OR, 1.06; 95%CI 1.04-1.08) and pre-ECMO arterial lactate (OR, 1.09; 95%CI 1.04-1.16) were independent predictors of hospital mortality. No differences between female and male patients were observed for other outcomes. Among propensity score-matched pairs, one-, three-, and five-year mortality were 60.6%, 65.0%, and 65.0% among men, and 71.3%, 71.3%, and 74.0% among women, respectively (p = 0.110, adjusted hazard ratio, 1.27; 95%CI 0.96-1.66). CONCLUSIONS: In postcardiotomy VA-ECMO, female patients demonstrated higher hospital mortality than men. Morbidity and late mortality were similar between the two groups.

OBJECTIVES: To compare the outcomes of patients with postcardiotomy shock treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO) only compared with VA-ECMO and intra-aortic balloon pump (IABP). DESIGN: A retrospective multicenter registry study. SETTING: At 19 cardiac surgery units. PARTICIPANTS: A total of 615 adult patients who required VA-ECMO from 2010 to 2018. The patients were divided into 2 groups depending on whether they received VA-ECMO only (ECMO only group) or VA-ECMO plus IABP (ECMO-IABP group). MEASUREMENTS AND MAIN RESULTS: The overall series mean age was 63 ± 13 years, and 33% were female. The ECMO-only group included 499 patients, and 116 patients were in the ECMO-IABP group. Urgent and/or emergent procedures were more common in the ECMO-only group. Central cannulation was performed in 47% (n = 54) in the ECMO-IABP group compared to 27% (n = 132) in the ECMO-only group. In the ECMO-IABP group, 58% (n = 67) were successfully weaned from ECMO, compared to 46% (n = 231) in the ECMO-only group (p = 0.026). However, in-hospital mortality was 63% in the ECMO-IABP group compared to 65% in the ECMO-only group (p = 0.66). Among 114 propensity score-matched pairs, ECMO-IABP group had comparable weaning rates (57% v 53%, p = 0.51) and in-hospital mortality (64% v 58%, p = 0.78). CONCLUSIONS: This multicenter study showed that adjunctive IABP did not translate into better outcomes in patients treated with VA-ECMO for postcardiotomy shock.

OBJECTIVE: Data on patients requiring a second run of venoarterial extracorporeal membrane oxygenation (VA-ECMO) support in patients affected by postcardiotomy cardiogenic shock (PCS) are very limited. The authors aimed to investigate the effect of a second run of VA-ECMO on PCS patient survival. DESIGN: Retrospective analysis of an international registry. SETTING: Multicenter study, tertiary university hospitals. PARTICIPANTS: Data on adult PCS patients receiving a second run of VA-ECMO. MEASUREMENTS AND MAIN RESULTS: A total of 674 patients with a mean age of 62.9 ± 12.7 years were analyzed, and 21 (3.1%) patients had a second run of VA-ECMO. None of them required more than two VA-ECMO runs. The median duration of VA-ECMO therapy was 135 hours (interquartile range [IQR] 61-226) in patients who did not require a VA-ECMO rerun. In the rerun VA-ECMO group the median overall duration of VA-ECMO therapy was 183 hours (IQR 107-344), and the median duration of the first run was 114 hours (IQR 66-169). Nine (42.9%) of the patients who required a second run of VA-ECMO died during VA-ECMO therapy, whereas five (23.8%) survived to hospital discharge. No differences between patients treated with single or second VA-ECMO runs were observed in terms of hospital mortality and late survival. In patients requiring a second VA-ECMO run, the actuarial survival estimates at three and 12 months after VA-ECMO weaning were 23.8% ± 9.3% and 19.6% ± 6.4%, respectively. CONCLUSIONS: Repeat VA-ECMO therapy is a valid treatment strategy for PCS patients. Early and late survivals are similar between patients who have undergone a single or second run of VA-ECMO.

OBJECTIVE: The optimal duration of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in patients affected by postcardiotomy cardiogenic shock (PCS) remains controversial. The present study was conducted to investigate the effect of VA-ECMO duration on hospital outcomes. DESIGN: Retrospective analysis of an international registry. SETTING: Multicenter study including 19 tertiary university hospitals. PARTICIPANTS: Between January 2010 and March 2018, data on PCS patients receiving VA-ECMO were retrieved from the multicenter PC-ECMO registry. INTERVENTIONS: Patients were stratified according to the following different durations of VA-ECMO therapy: ≤three days, four-to-seven days, eight-to-ten days, and >ten days. MEASUREMENTS AND MAIN RESULTS: A total of 725 patients, with a mean age of 62.9 ± 12.9 years, were included. The mean duration of VA-ECMO was 7.1 ± 6.3 days (range 0-39 d), and 39.4% of patients were supported for ≤three days, 29.1% for four-seven days, 15.3% for eight-ten days, and finally 20.7% for >ten days. A total of 391 (53.9%) patients were weaned from VA-ECMO successfully; however, 134 (34.3%) of those patients died before discharge. Multivariate logistic regression showed that prolonged duration of VA-ECMO therapy (four-seven days: adjusted rate 53.6%, odds ratio [OR] 0.28, 95% confidence interval [CI] 0.18-0.44; eight-ten days: adjusted rate 61.3%, OR 0.51, 95% CI 0.29-0.87; and >ten days: adjusted rate 59.3%, OR 0.49, 95% CI 0.31-0.81) was associated with lower risk of mortality compared with VA-ECMO lasting ≤three days (adjusted rate 78.3%). Patients requiring VA-ECMO therapy for eight-ten days (OR 1.96, 95% CI 1.15-3.33) and >10 days (OR 1.85, 95% CI 1.14-3.02) had significantly greater mortality compared with those on VA-ECMO for 4 to 7 days. CONCLUSIONS: PCS patients weaned from VA-ECMO after four-seven days of support had significantly less mortality compared with those with shorter or longer mechanical support.

OBJECTIVE: To investigate the frequency, predictors, and outcomes of neurologic injury in adults treated with postcardiotomy extracorporeal membrane oxygenation (PC-ECMO). DESIGN: A retrospective multicenter registry study. SETTING: Twenty-one European institutions where cardiac surgery is performed. PARTICIPANTS: A total of 781 adult patients who required PC-ECMO during 2010 to 2018 were divided into patients with neurologic injury (NI) and patients without neurologic injury (NNI). MEASUREMENTS AND MAIN RESULTS: Baseline and operative data, in-hospital outcomes, and long-term survival were compared between the NI and the NNI groups. Predictors of neurologic injury were identified. A subgroup analysis according to the type of neurologic injury was performed. Overall, NI occurred in 19% of patients in the overall series, but the proportion of patients with NI ranged from 0% to 65% among the centers. Ischemic stroke occurred in 84 patients and hemorrhagic stroke in 47 patients. Emergency procedure was the sole independent predictor of NI. In-hospital mortality was higher in the NI group than in the NNI group (79% v 61%, p < 0.001). The one-year survival was lower in the NI group (17%) compared with the NNI group (37%). Long-term survival did not differ between patients with ischemic stroke and those with hemorrhagic stroke. CONCLUSION: Neurologic injury during PC-ECMO is common and associated with a dismal prognosis. There is considerable interinstitutional variation in the proportion of neurologic injury in PC-ECMO-treated adults. Well-known risk factors for stroke are not associated with neurologic injury in this setting.

The aim of the present study is to report our long-term experience with the HeartWare Ventricular Assist System (HVAD). Between July 2009 and February 2018, a total of 103 patients (mean age 50.0 ± 14.4, range 28-74 years; 22 females) received HVAD implantation in a single center institution. A total of 26 (25.4%) patients were in cardiogenic shock preoperatively and received extracorporeal life support (ECLS) prior to HVAD implantation. The aim of left ventricular assist device (LVAD) implantation was bridge to transplantation (BT) in 59 (57.3%), destination therapy (DT) in 28 (27.2%), and bridge to decision in 16 (15.5%). There were 211.1 total patient years of support. Mean survival was 2.05 ± 2.14 years. Kaplan-Meier analysis showed an overall survival rate of 69.7%, 56.7%, 46.0%, and 25.0% at 1, 2, 4, and 8 years, respectively. A total of 23 patients (22.3%) died during the hospital stay. Of them 65.2% (15 patients) were preoperatively in cardiogenic shock (INTERMACS 1). Sub-analysis of the BT patients showed a mean survival of 2.45 ± 2.29 years with a survival rate of 85.1%, 75.1%, 67.2%, and 44.8% at 1, 2, 4, and 8 years, respectively. Among them, 20 patients received heart transplantation on follow-up. Mean survival of DT patients was 2.18 ± 1.91 years with a survival rate of 67.9%, 49.0%, and 25.1% at 1, 2, and 4 years, respectively. At latest follow-up in September 2018, 26 patients (25.24%) were still on LVAD. A total of five patients completed 6 years on LVAD, of them two were supported over 8 years. The most common adverse event reported was gastrointestinal bleeding requiring rehospitalization (0.161 EPPY). A total of 19 patients reported disabling stroke. Pump thrombosis was diagnosed in six patients (5.8%) (0.02 EPPY), of them four patients underwent pump exchange. To the best of our knowledge, this is the longest experience with HVAD reported so far. Patients supported with an HVAD show a satisfactory long-term survival. Further multicenter evaluations are needed to confirm these single-center results.

OBJECTIVE: This study was planned to pool existing data on outcome and to evaluate the efficacy of postcardiotomy venoarterial extracorporeal membrane oxygenation (VA-ECMO) in adult patients. DESIGN: Systematic review of the literature and meta-analysis. SETTING: Multi-institutional study. PARTICIPANTS: Adult patients with acute heart failure immediately after cardiac surgery. INTERVENTIONS: VA-ECMO after cardiac surgery. Studies evaluating only heart transplant patients were excluded from this analysis. MEASUREMENTS AND MAIN RESULTS: A literature search was performed to identify studies published since 2000. Thirty-one studies reported on 2,986 patients (mean age, 58.1 years) who required postcardiotomy VA-ECMO. The weaning rate from VA-ECMO was 59.5% and hospital survival was 36.1% (95% CI 31.5-40.8). The pooled rate of reoperation for bleeding was 42.9%, major neurological event 11.3%, lower limb ischemia 10.8%, deep sternal wound infection/mediastinitis 14.7%, and renal replacement therapy 47.1%. The pooled mean number of transfused red blood cell units was 17.7 (95% CI 13.3-22.1). The mean stay in the intensive care unit was 13.3 days (95% CI 10.2-16.4). Survivors were significantly younger (mean, 55.7 v 63.6 years, p = 0.015) and their blood lactate level before starting VA-ECMO was lower (mean, 7.7 v 10.7 mmol/L, p = 0.028) than patients who died. One-year survival rate was 30.9% (95% CI 24.3-37.5). CONCLUSIONS: Pooled data showed that VA-ECMO may salvage one-third of patients unresponsive to any other resuscitative treatment after adult cardiac surgery.

BACKGROUND AND AIM OF THE STUDY: Transcatheter aortic valve implantation (TAVI), especially via the transfemoral (TF) route, is increasingly performed in patients considered in the 'gray zone' between TAVI and surgery. However, the best treatment option in this patient population remains to be established. METHODS: Since 2010, a total of 923 patients underwent either TAVI (n = 538) or sutureless aortic valve replacement (AVR) (n = 385) at the authors' institutions. Among these patients, 79 treated with TF-TAVI were compared with 79 propensity score-matched patients who had undergone elective isolated AVR with the sutureless Perceval bioprosthesis. RESULTS: In-hospital mortality did not differ significantly between patients who underwent sutureless AVR or TF-TAVI (none versus three; 3.8%; p = 0.123). Similarly, postoperative complications were comparable between groups. Atrioventricular block requiring postoperative pacemaker implantation occurred in seven patients (9.2%) of the sutureless group and in eight patients (11.1%) of the TF-TAVI group (p = 0.455). The use of blood products varied between groups in terms of red blood cell transfusions (1.7 ± 2 versus 0.3 ± 0.9 units for the sutureless group versus TF-TAVI group; p <0.001). Paravalvular leakage at discharge was present in three patients (3.8%) in the sutureless group and in 26 patients (32.9%) in the TF-TAVI group (p <0.001). The mean follow up was longer for sutureless AVR (36 ± 21 versus 27 ± 20 months; p = 0.003). Survival rates were 97.5% and 84.8% in the sutureless and TF-TAVI groups, respectively (p = 0.001). CONCLUSIONS: Both, TF-TAVI and sutureless AVR are well-standardized, safe and effective procedures. TF-TAVI seems to be a valuable alternative to surgical AVR for frail patients, reducing the need for perioperative blood transfusion. In contrast, in patients with a favorable long-term survival outcome, minimally invasive AVR remains the procedure of choice as it is associated with better long-term results.

This study provides early results of re-operations after the prior surgical treatment of acute type A aortic dissection (AAD) and identifies risk factors for mortality. Between May 2003 and January 2014, 117 aortic re-operations after an initial operation for AAD (a mean time from the first procedure was 3.98 years, with a range of 0.1-20.87 years) were performed in 110 patients (a mean age of 59.8 ± 12.6 years) in seven European institutions. The re-operation was indicated due to a proximal aortic pathology in ninety cases: twenty aortic root aneurysms, seventeen root re-dissections, twenty-seven aortic valve insufficiencies and twenty-six proximal anastomotic pseudoaneurysms. In fifty-eight cases, repetitive surgical treatment was subscripted because of distal aortic pathology: eighteen arch re-dissections, fifteen arch dilation and twenty-five anastomotic pseudoaneurysms. Surgical procedures comprised a total of seventy-one isolated proximals, thirty-one isolated distals and fifteen combined interventions. In-hospital mortality was 19.6 % (twenty-three patients); 11.1 % in patients with elective/urgent indication and 66.6 % in emergency cases. Mortality rates for isolated proximal, distal and combined operations regardless of the emergency setting were 14.1 % (10 pts.), 25.8 % (8 pts.) and 33.3 % (5 pts.), respectively. The causes of death were cardiac in eight, neurological in three, MOF in five, sepsis in two, bleeding in three and lung failure in two patients. A multivariate logistic regression analysis revealed that risk factors for mortality included previous distal procedure (p = 0.04), new distal procedure (p = 0.018) and emergency operation (p < 0.001). New proximal procedures were not found to be risk factors for early mortality (p = 0.15). This multicenter experience shows that the outcome of REAAD is highly dependent on the localization and extension of aortic pathology and the need for emergency treatment. Surgery in an emergency setting and distal re-do operations after previous AAD remain a surgical challenge, while proximal aortic re-operations show a lower mortality rate. Foresighted decision-making is needed in cases of AAD repair, as the results are essential preconditions for further surgical interventions.

We report on our experience with a simplified elephant trunk (ET) procedure with a multi-branched prosthesis (Vascutek(®) Siena™ Collared Graft). It consists of a proximal portion (20 cm) with prefabricated side branches, a collar and a distal portion (30 cm). The collar, which can be trimmed into any desired diameter, constitutes the suture portion to the descending aorta. Radiopaque markers in the distal portion indicate the landing zone. Between January 2011 and June 2013, 20 consecutive patients (10 women; mean age, 66 ± 9.3 years) underwent ET procedure, including 6 re-do cases. Underlying aortic diseases were acute dissection (n = 6), chronic dissection (n = 4), aneurysm (n = 8) and PAU (n = 2). Mean preoperative diameter of the descending aorta was 49.1 ± 12.9 mm (range 74.7-29.7 mm). Concomitant procedures included ascending aortic replacement in 16 patients; root replacement in 2; AVR in 2, CABG in 3 and mitral repair in 1 patient. CPB time was 263 ± 94 min; mean duration of ACP was 65 ± 14 min. Two patients died on POD 8 and 78, respectively. Major adverse events included stroke (n = 1), resternotomy for bleeding (n = 2), renal failure requiring temporary dialysis (n = 1) and recurrent nerve paresis (n = 2). After a mean follow-up of 10 ± 8 months, all discharged patients were alive. Seven patients underwent stent-graft implantation of the descending aorta and one patient underwent open descending aortic replacement. The last generation of multi-branched arch prosthesis and especially the Vascutek(®) Siena™ Collared Graft make ET procedure a reasonable treatment option even in patients with acute aortic dissection.

Reports on third-generation centrifugal intrapericardial pumps (HeartWare International, Inc., Framingham, MA, USA) have shown better survival results than the previous-generation devices. However, outcomes depending on the preoperative level of stability can substantially differ, resulting in a limited analysis of potentialities and drawbacks of a given device. In the present study we sought to compare in our single-center experience the survival results of this third-generation device with previous left ventricular systems taking into account the different preoperative Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) levels. Between February 1993 and March 2012, 287 patients underwent assist device implantation in our university hospital (INTERMACS Level 1-2 = 158 patients; INTERMACS Level 3-4-5 = 129 patients). Assist devices implanted were: Group A (HVAD HeartWare, n = 52), group B (previous continuous-flow ventricular assist device [VAD], InCor [Berlin Heart, Berlin, Germany], n = 37; VentrAssist [VentraCor, Inc., Chatswood, NSW, Australia], n = 7; DeBakey [MicroMed Cardiovascular, Inc., Houston, TX, USA], n = 32), and group C (pulsatile systems, n = 159). After cumulative support duration of 54 436 days and a mean follow-up of 6.21 ± 7.46 months (range 0-45.21 months), log-rank analysis revealed a survival for group A of 82.0%, 70.4%, and 70.4%; for group B of 84.0%, 48.2%, 33.7%; and for group C of 71.6%, 46.1%, 33.8%, at 1, 12, and 24 months respectively, with a significantly (P = 0.013) better outcome for group A. When stratifying the survival on the basis of INTERMACS level, no significant survival improvement was observed among all patients who underwent VAD implantation in INTERMACS 1-2 (P = 0.47). However, among patients who underwent elective VAD implantation (INTERMACS 3-4-5), group A had a significantly better outcome (P = 0.005) compared with the other INTERMACS-matched groups (B,C) with a survival rate of 88.8% in group A versus 34.2% in group B and 45.6% in group C at 24 months, respectively. Elective HVAD system implantation shows improved survival benefit over the other INTERMACS-matched devices. Moreover, preoperative unstable hemodynamics resulted in a poor prognosis independently from the pump generation.

BACKGROUND: The outcomes after prolonged treatment in the intensive care unit (ICU) after surgery for Stanford type A aortic dissection (TAAD) have not been previously investigated. METHODS: This analysis included 3538 patients from a multicenter study who underwent surgery for acute TAAD and were admitted to the cardiac surgical ICU. RESULTS: The mean length of stay in the cardiac surgical ICU was 9.9±9.5 days. The mean overall costs of treatment in the cardiac surgical ICU 24086±32084 . In-hospital mortality was 14.8% and 5-year mortality was 30.5%. Adjusted analyses showed that prolonged ICU stay was associated with significantly lower risk of in-hospital mortality (adjusted OR 0.971, 95%CI 0.959-0.982), and of five-year mortality (adjusted OR 0.970, 95%CI 0.962-0.977), respectively. Propensity score matching analysis yielded 870 pairs of patients with short ICU stay (2-5 days) and long ICU stay (>5 days) with balanced baseline, operative and postoperative variables. Patients with prolonged ICU stay (>5 days) had significantly lower in-hospital mortality (8.9% vs. 17.4%, <0.001) and 5-year mortality (28.2% vs. 30.7%, P=0.007) compared to patients with short ICU-stay (2-5 days). CONCLUSIONS: Prolonged ICU stay was common after surgery for acute TAAD. However, when adjusted for multiple baseline and operative variables as well as adverse postoperative events and the cluster effect of hospitals, it was associated with favorable survival up to 5 years after surgery.

BACKGROUND: Extended aortic repair is considered a key issue for the long-term durability of surgery for DeBakey type 1 aortic dissection. The risk of aortic degeneration may be higher in young patients due to their long life expectancy. The early outcome and durability of aortic surgery in these patients were investigated in the present study. METHODS: The subjects of the present analysis were patients under 60 years old who underwent surgical repair for acute DeBakey type 1 aortic dissection at 18 cardiac surgery centres across Europe between 2005 and 2021. Patients underwent ascending aortic repair or total aortic arch repair using the conventional technique or the frozen elephant trunk technique. The primary outcome was 5-year cumulative incidence of reoperation on the distal aorta. RESULTS: Overall, 915 patients underwent surgical ascending aortic repair and 284 patients underwent surgical total aortic arch repair. The frozen elephant trunk procedure was performed in 128 patients. Among 245 propensity score-matched pairs, total aortic arch repair did not decrease the rate of distal aortic reoperation compared to ascending aortic repair (5-year cumulative incidence, 6.7% versus 6.7%, subdistributional hazard ratio 1.127, 95% c.i. 0.523 to 2.427). Total aortic arch repair increased the incidence of postoperative stroke/global brain ischaemia (25.7% versus 18.4%, P = 0.050) and dialysis (19.6% versus 12.7%, P = 0.003). Five-year mortality was comparable after ascending aortic repair and total aortic arch repair (22.8% versus 27.3%, P = 0.172). CONCLUSIONS: In patients under 60 years old with DeBakey type 1 aortic dissection, total aortic arch replacement compared with ascending aortic repair did not reduce the incidence of distal aortic operations at 5 years. When feasible, ascending aortic repair for DeBakey type 1 aortic dissection is associated with satisfactory early and mid-term outcomes.

OBJECTIVES: Gender difference in the outcome after type A aortic dissection (TAAD) surgery remains an issue of ongoing debate. In this study, we aimed to evaluate the impact of gender on the short- and long-term outcome after surgery for TAAD. METHODS: A multicentre European registry retrospectively included all consecutive TAAD surgery patients between 2005 and 2021 from 18 hospitals across 8 European countries. Early and late mortality, and cumulative incidence of aortic reoperation were compared between genders. RESULTS: A total of 3902 patients underwent TAAD surgery, with 1185 (30.4%) being females. After propensity score matching, 766 pairs of males and females were compared. No statistical differences were detected in the early postoperative outcome between genders. Ten-year survival was comparable between genders (47.8% vs 47.1%; log-rank test, P = 0.679), as well as cumulative incidences of distal or proximal aortic reoperations. Ten-year relative survival compared to country-, year-, age- and sex-matched general population was higher among males (0.65) compared to females (0.58). The time-period subanalysis revealed advancements in surgical techniques in both genders over the years. However, an increase in stroke was observed over time for both populations, particularly among females. CONCLUSIONS: The past 16 years have witnessed marked advancements in surgical techniques for TAAD in both males and females, achieving comparable early and late mortality rates. Despite these findings, late relative survival was still in favour of males.

Surgery for type A aortic dissection (TAAD) is associated with a high risk of early mortality. The prognostic impact of a new classification of the urgency of the procedure was evaluated in this multicenter cohort study. Data on consecutive patients who underwent surgery for acute TAAD were retrospectively collected in the multicenter, retrospective European Registry of TAAD (ERTAAD). The rates of in-hospital mortality of 3,902 consecutive patients increased along with the ERTAAD procedure urgency grades: urgent procedure 10.0%, emergency procedure grade 1 13.3%, emergency procedure grade 2 22.1%, salvage procedure grade 1 45.6%, and salvage procedure grade 2 57.1% (p <0.0001). Preoperative arterial lactate correlated with the urgency grades. Inclusion of the ERTAAD procedure urgency classification significantly improved the area under the receiver operating characteristics curves of the regression model and the integrated discrimination indexes and the net reclassification indexes. The risk of postoperative stroke/global brain ischemia, mesenteric ischemia, lower limb ischemia, dialysis, and acute heart failure increased along with the urgency grades. In conclusion, the urgency of surgical repair of acute TAAD, which seems to have a significant impact on the risk of in-hospital mortality, may be useful to improve the stratification of the operative risk of these critically ill patients. This study showed that salvage surgery for TAAD is justified because half of the patients may survive to discharge.

Surgery for type A aortic dissection (TAAD) is frequently complicated by neurologic complications. The prognostic impact of neurologic complications of different nature has been investigated in this study. The subjects of this analysis were 3,902 patients who underwent surgery for acute TAAD from the multicenter European Registry of Type A Aortic Dissection (ERTAAD). During the index hospitalization, 722 patients (18.5%) experienced stroke/global brain ischemia. Ischemic stroke was detected in 539 patients (13.8%), hemorrhagic stroke in 76 patients (1.9%) and global brain ischemia in 177 patients (4.5%), with a few patients having had findings of more than 1 of these conditions. In-hospital mortality was increased significantly in patients with postoperative ischemic stroke (25.6%, adjusted odds ratio [OR] 2.422, 95% confidence interval [CI] 1.825 to 3.216), hemorrhagic stroke (48.7%, adjusted OR 4.641, 95% CI 2.524 to 8.533), and global brain ischemia (74.0%, adjusted OR 22.275, 95% CI 14.537 to 35.524) compared with patients without neurologic complications (13.5%). Similarly, patients who experienced ischemic stroke (46.3%, adjusted hazard ratio [HR] 1.719, 95% CI 1.434 to 2.059), hemorrhagic stroke (62.8%, adjusted HR 3.236, 95% CI 2.314 to 4.525), and global brain ischemia (83.9%, adjusted HR 12.777, 95% CI 10.325 to 15.810) had significantly higher 5-year mortality than patients without postoperative neurologic complications (27.5%). The negative prognostic effect of neurologic complications on survival vanished about 1 year after surgery. In conclusion, postoperative ischemic stroke, hemorrhagic stroke, and global cerebral ischemia increased early and midterm mortality after surgery for acute TAAD. The magnitude of risk of mortality increased with the severity of the neurologic complications, with postoperative hemorrhagic stroke and global brain ischemia being highly lethal complications.

PURPOSE OF REVIEW: Diabetes mellitus and its related comorbidities present a growing challenge in perioperative medicine. And also largely independent from a history of diabetes, dysregulations of glucose homeostasis occur as part of the body's stress response. Dysregulations of glucose homeostasis, acute or chronic, are closely correlated with impaired prognosis in perioperative medicine. Treatment strategies remain somewhat controversial, as both the affliction and its correction have a blind side. RECENT FINDINGS: Anesthesia requires vigilant attention to diabetes-related comorbidities such as neuropathy, angiopathy, cardiopathy and immune dysfunction. Dysregulations of glycemia of any kind, in other words, hypoglycemia and hyperglycemia and fluctuations of blood glucose, should be avoided. Target glycemia remains a matter of discussion: moderate, achievable glycemic target below 180 or 150âmg/dl appears to be reasonable. Modern technical developments like continuous glucose measurement devices and computer-assisted control algorithms are under development, and will hopefully facilitate perioperative glycemic control in the future. SUMMARY: Literature clearly shows that leaving glycemic control out of focus is dangerous for the patient; efforts to control glycemia to a moderate target improve the patient's outcome.
