ABSTRACT
OBJECTIVES: Cardiopulmonary resuscitation (CPR) aggravates the pre-existing dismal prognosis of patients suffering from acute type A aortic dissection (ATAAD). We aimed to identify factors affecting survival and outcome in ATAAD patients requiring CPR at presentation at 2 European aortic centres. METHODS: Data on 112 surgical candidates and undergoing preoperative CPR were retrospectively evaluated. Patients were divided into 2 groups according to 30-day mortality. A multivariable model identified predictors for 30-day mortality. RESULTS: Preoperative death occurred in 23 patients (20.5%). In the remaining 89 surgical patients (79.5%) circulatory arrest time (41 ± 20 min in 30-day non-survivors vs 30 ± 13 min in 30-day survivor, P = 0.003) as well as cardiopulmonary bypass time (320 ± 132 min in 30-day non-survivors vs 252 ± 140 min in 30-day survivor, P = 0.020) time was significantly longer in patients with worse outcome. Thirty-day mortality of the total cohort was 61.6% (n = 69) with cardiac failure in 48% and aortic rupture or haemorrhagic shock (28%) as predominant reasons of death. Age [odds ratio (OR) 1.04, 95% confidence interval (CI) 1.01-1.09, P = 0.034], preoperative coronary (OR 3.42, 95% CI 1.34-9.26, p = 0.012) and spinal malperfusion (OR 12.49, 95% CI 1.83-225.02, P = 0.028) emerged as independent predictors for 30-day mortality while CPR due to tamponade was associated with improved early survival (OR 0.29, 95% CI 0.091-0.81, P = 0.023). CONCLUSIONS: Assessment of underlying cause for CPR is mandatory. Pericardial tamponade, rapidly resolved with pericardial drainage, is a predictor for improved survival, while age and presence of coronary and spinal malperfusion are associated with dismal outcome in this high-risk patient group.

OBJECTIVES: Mechanical strain plays a major role in the development of aortic calcification. We hypothesized that (i) valvular calcifications are most pronounced at the localizations subjected to the highest mechanical strain and (ii) calcification patterns are different in patients with bicuspid and tricuspid aortic valves. METHODS: Multislice computed tomography scans of 101 patients with severe aortic stenosis were analysed using a 3-dimensional post-processing software to quantify calcification of tricuspid aortic valves (n = 51) and bicuspid aortic valves (n = 50) after matching. RESULTS: Bicuspid aortic valves exhibited higher calcification volumes and increased calcification of the non-coronary cusp with significantly higher calcification of the free leaflet edge. The non-coronary cusp showed the highest calcium load compared to the other leaflets. Patients with annular calcification above the median had an impaired survival compared to patients with low annular calcification, whereas patients with calcification of the free leaflet edge above the median did not (P = 0.53). CONCLUSIONS: Calcification patterns are different in patients with aortic stenosis with bicuspid and tricuspid aortic valves. Patients with high annular calcification might have an impaired prognosis.

Background: Diagnosis and management of low-flow/low-gradient aortic stenosis are very challenging. Resting echocardiography is not capable of differentiating between different types and origins of low-flow and low-gradient state in aortic valve stenosis. Therefore, dobutamine stress echocardiography (DSE) and cardiac computed tomography (CCT) are necessary. This case report should illustrate the importance of these assessments. Case summary: A 73-year-old woman presented to our emergency department with New York Heart Association III symptoms of exertional dyspnoea. In addition, the patient complained of fatigue and low resilience. On physical examination, auscultation revealed a systolic murmur over the aortic valve. Further diagnostic steps revealed a low-flow/low-gradient aortic valve stenosis (LF/LGAS) without contractile reserve (CR) in DSE and massive valve calcification in CCT. Discussion: In this case, we demonstrate the importance of different assessments and workflow. The prognosis of LF/LGAS has been re-evaluated during the last decade and the current guidelines recommend the treatment of such patients even in the absence of CR. Furthermore, we are discussing the results of LF/LGAS.
ABSTRACT
Transaortic (TAo) transcatheter aortic valve implantation has become a valid alternative access route in patients with unsuitable femoral arteries. The current literature does not allow to clearly favor one of the alternative access routes. Every approach has its specific advantages. Transaortic (TAo) access is of particular importance in the case of calcifications of the supra-aortic branches and the aortic arch, as under these circumstances other alternative access routes, such as transaxillary or transcarotid, are not feasible. The purpose of this minireview is to give an overview and update on TAo transcatheter aortic valve implantation focusing on indication, technical aspects, and recent clinical data.
ABSTRACT
OBJECTIVES: The aim of this study was to evaluate gender differences in the pre- and postoperative course in patients with acute aortic dissection type A. METHODS: Of all patients undergoing surgery from 2000 to 2020, data on symptoms at presentation, operative strategy and postoperative course were analyzed. Long-term follow-up was obtained through visits at our outpatient clinic or via telephone interviews. RESULTS: Out of 394 patients, 32% (n = 126) were female. Women suffered from aortic dissection type A at an older age (women 67.5 years vs men 57 years; P > 0.001) and experienced a more aggressive preoperative course leading to critical presentation or even lethal rupture [women 7.9% (n = 10) vs men 2.2% (n = 6); P = 0.008]. Chest pain as initial symptom was more common in men [women 59.5% (n = 75) vs men 73.5% (n = 197); P = 0.005]. Perfusion of the right carotid was impaired more often [women 22.5% (n = 27) vs men 13.7% (n = 36); P = 0.031] and preoperative rate of neurological dysfunction was higher in women [women 23% (n = 29) vs men 14.2% (n = 38); P = 0.028]. Time from symptom onset to surgery did not differ between gender. Surgical repair was less extensive and faster in women. Female patients were more likely to suffer from postoperative neurological injury [women 23.8% (n = 30) vs men 10.2% (n = 40); P = 0.023]. We detected impaired 30-day and long-term survival in women. CONCLUSIONS: Women represent an older and sicker patient collective. Preoperative course of aortic dissection type A is more aggressive and complicated in women. While time from onset of symptoms to surgery did not differ between gender, neurological outcome and survival were impaired in women.

OBJECTIVES: The aim of this study was to externally validate a lab-based risk score (lactate, creatinine, aspartate aminotransferase, alanine aminotransferase or bilirubin) by Ghoreishi et al. to predict perioperative mortality in patients undergoing surgical repair for acute type A aortic dissection. METHODS: The risk score to predict operative mortality was applied to a large and homogenous validation cohort that consisted of 632 patients undergoing surgery for acute type A aortic dissection in 2 centres. Multivariable regression analysis was performed to determine the impact on survival. Receiver operating characteristics with deduced area under the curve were used to assess the ability to predict perioperative mortality. RESULTS: A total of 632 patients (54% male, mean age 62 ± 14 years) were assigned to 3 different risk groups according to the calculated mortality score [low risk <7 (31.2%), moderate risk 7-20 (36.1%) and high >20 (32.7%)]. Perioperative mortality was 8% in the low-risk group, 10% in the moderate-risk group and 24% in the high-risk group (P < 0.0001). Receiver operating characteristic analysis of this new score revealed an area under the curve of 0.69 with adequate calibration. In addition, multivariable analysis revealed an independet assocation with perioperative mortality (odds ratio 1.509; 95% confidence interval 1.042-2.185). While overall survival differed between the risk groups (P < 0.0001), the score does not serve as an independent predictor of long-term mortality when adjusted for relevant covariates. CONCLUSIONS: The external validation process confirmed that a newly proposed risk score offers clinicians a helpful and reliable tool to improve the preoperative risk assessment of acute type A aortic dissection patients based on easily accessible and broadly available laboratory parameters.

BACKGROUND: The Toronto Aortic Stenosis Quality of Life Questionnaire (TASQ) is a validated instrument for assessing quality of life (QoL) in patients with severe aortic stenosis (AS). In this study, we evaluated health status outcomes, based on the TASQ, in patients with severe AS undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). METHODS: The TASQ registry was a prospective observational registry. Patients with severe AS from nine centres in Europe and one in Canada underwent either SAVR or transfemoral TAVR. Patients completed the TASQ, Kansas City Cardiomyopathy Questionnaire and Short Form-12 V.2 prior to the intervention, predischarge, and at 30-day and 3-month follow-ups. Primary end point was the TASQ score. RESULTS: In both the TAVR (n=137) and SAVR (n=137) cohorts, significant increases were observed in all three scores. The overall TASQ score improved as did all but one of the individual domains at 3 months after the intervention (p<0.001). TASQ health expectations were the only domain which worsened (p<0.001). Across TASQ subscores, significant changes were evident from the time of discharge in the TAVR and 30-day follow-up in the SAVR cohort. In a categorical analysis of the TASQ, 39.7% of the TAVR group and 35.0% of the SAVR group had a substantially improved health status at 3 months compared with baseline. CONCLUSIONS: The TASQ captured changes in QoL among patients with severe AS who were treated with TAVR or SAVR. QoL improved substantially after either intervention, as indicated by changes in the TASQ overall score at 3 months. TRIAL REGISTRATION NUMBER: NCT03186339.

Transcatheter aortic valve replacement (TAVR) has shown to reduce mortality compared to surgical aortic valve replacement (sAVR). However, it is unknown which procedure is associated with better post-procedural valvular function. We conducted a meta-analysis of randomized clinical trials that compared TAVR to sAVR for at least 2 years. The primary outcome was post-procedural patient-prosthesis-mismatch (PPM). Secondary outcomes were post-procedural and 2-year: effective orifice area (EOA), paravalvular gradient (PVG) and moderate/severe paravalvular leak (PVL). We identified 6 trials with a total of 7022 participants with severe aortic stenosis. TAVR was associated with 37% (95% CI [0.51-0.78) mean RR reduction of post-procedural PPM, a decrease that was not affected by the surgical risk at inclusion, neither by the transcatheter heart valve system. Postprocedural changes in gradient and EOA were also in favor of TAVR as there was a pooled mean difference decrease of 0.56 (95% CI [0.73-0.38]) in gradient and an increase of 0.47 (95% CI [0.38-0.56]) in EOA. Additionally, self-expandable valves were associated with a higher decrease in gradient than balloon ones (beta = 0.38; 95% CI [0.12-0.64]). However, TAVR was associated with a higher risk of moderate/severe PVL (pooled RR: 9.54, 95% CI [5.53-16.46]). All results were sustainable at 2 years.

OBJECTIVES: Transit-time flow measurement is a recognized method for graft evaluation in coronary surgery. However, single flow measurement has been associated with a low specificity for detecting graft dysfunction. The goal of this study was to assess the value of transit-time flow measurement for assessing in situ internal mammary artery grafts during non-existent native coronary circulation and the relevance of collateral blood flow in target vessels. METHODS: Between 2014 and 2018, a total of 134 patients undergoing on-pump coronary artery bypass grafting were evaluated using transit-time flow measurement. We analysed 111 single left internal mammary artery and 57 single right internal mammary artery bypasses. Correlations between coronary relevant parameters were calculated using Spearman's ρ coefficient. Risk factors for decreased flow with an arrested heart (FAH) <30 ml/min and an increased pulsatility index (PI) >3.0 as well as flow reduction >30% were calculated. RESULTS: FAH correlated with the diameter of the target vessel (Spearman's ρ = 0.32; P < 0.001), the amount of blood distribution (Spearman's ρ = 0.34; P < 0.001), the PI (Spearman's ρ = 0.19; P = 0.019) and the degree of stenosis (Spearman's ρ = -0.17; P = 0.042). The percentage of flow change was found to correlate with the PI (Spearman's ρ = -0.47; P < 0.0001), the degree of stenosis (Spearman's ρ = 0.42; P < 0.001), the diameter of the target vessel (Spearman's ρ = -0.22; P = 0.008) and the area of blood distribution (Spearman's ρ = -0.19; P = 0.018). A small blood distribution area was the only risk factor for decreased FAH [odds ratio (OR) 8.43, confidence interval (CI) 95% (3.04-23.41); P < 0.001]. Binary logistic regression identified PI [OR 2.05, CI 95% (1.36-3.10); P = 0.001], FAH [OR 0.98, CI 95% (0.97-0.99); P = 0.005] and degree of stenosis [OR 0.95, CI 95% (0.92-0.99); P = 0.011] as risk factors for decreased flow after cardiopulmonary bypass (<30 ml/min). An increased PI (>3) was mainly influenced by percentage of flow change [OR 0.99, CI 95% (0.98-1.00); P = 0.031]. CONCLUSIONS: FAH and percentage of flow change are related to the dimensions of the target vessel and the degree of stenosis. The addition of flow measurements with the heart arrested provides additional information about the bypass graft, the quality of the anastomosis and the physiology of the coronary circulation.

BACKGROUND AND AIM OF THE STUDY: The objective was to evaluate whether there is a decisive time interval for patients to undergo surgery and to analyze if a rapid response in acute aortic dissection type A (AADA) affects patient selection. METHODS: In 283 patients undergoing surgery for AADA, median time from onset of initial symptoms to skin incision was 6.9 hours (interquartile range [IQR], 5.0-11.7 hours). Patients were divided into three groups according to median time point of surgery (median ± 3 hours, i.e., 4-10; < 4; and >10 hours). RESULTS: Almost 50% of patients presented in a critical preoperative state at hospital admission. Subanalysis identified patients being operated within 4 hours as an exclusive high-risk cohort (higher rates of preoperative neurologic dysfunction, tamponade, and cardiopulmonary resuscitation). Patients undergoing surgery between 4 and 10 hours showed a significantly better long-term survival (p = 0.021). Surgery within this time interval had a clear protective effect on 30-day mortality (odds ratio [OR]: 0.448. 95% confidence interval [CI]: 0.219-0.915). High age (OR: 1.037; 95% CI: 1.008-1.067), preoperative malperfusion syndrome (OR: 2.802; 95% CI: 1.351-5.811), and preoperative tamponade (OR: 2.621; 95% CI: 1.171-5.866) were factors predicting 30-day mortality. CONCLUSION: Rapid response in AADA interacts with the natural course of the disease resulting in an overrepresentation of critical patients. While the cohort below 4 hours represents the high-risk patients, time from symptom onset to initiation of surgery should not exceed 10 hours.

AIMS: There is no quality of life tool specifically developed for patients with severe aortic stenosis (AS) to assess how this chronic condition and its treatment affect patients. The Toronto Aortic Stenosis Quality of Life Questionnaire (TASQ) has been developed to overcome this gap. The results of the validation of the TASQ in patients undergoing treatment for severe AS are presented. METHODS AND RESULTS: Prospective study at 10 centres in Europe and Canada, which enrolled 274 patients with severe symptomatic AS undergoing surgical or transcatheter aortic valve replacement. Mean TASQ score at baseline was 71.2 points and increased to 88.9 three months after aortic valve implantation (P < 0.001). Increases were seen for the emotional impact (32.0 to 39.0; P < 0.001), physical limitations (14.8 to 22.0; P < 0.001), and physical symptoms (8.5 vs. 11.0; P < 0.001) domains. Internal consistency was good/excellent for overall TASQ score (α = 0.891) and for the physical limitation, emotional impact, and social limitation domains (α = 0.815-0.950). Test-retest reliability was excellent or strong for the overall TASQ (intraclass correlation coefficient of 0.883) and for the physical symptoms, physical limitation, emotional impact, and social limitation domains (intraclass correlation coefficient of 0.791-0.895). Responsiveness was medium overall (Cohen's d = 0.637) and medium/large for physical symptoms, emotional impact, and physical limitations (0.661-0.812). Sensitivity to change was significant for physical symptoms, physical limitations (both P < 0.001), emotional impact (P = 0.003), and social limitations (P = 0.038). CONCLUSIONS: The TASQ is a new, brief, self-administered, and clinically relevant health-specific tool to measure changes in quality of life in patients with AS undergoing an intervention.

OBJECTIVES: Immediate surgical repair for type A aortic dissection is gold standard and at most centres is performed by the surgeon on call during night-time and weekends. The objective was to evaluate whether emergency surgery during night-time or weekends has an influence on 30-day mortality. METHODS: In 319 patients undergoing surgery for type A aortic dissection, skin incision was documented. Patients were divided into 2 groups according to the time point of skin incision (05:00 a.m. to 07:00 p.m. = daytime group; 07:01 p.m. to 04:59 a.m. = night-time group). We also noted whether their surgeries were started on weekdays (Monday 00:00 to Friday 23:59) or weekends (Saturday 00:00 to Sunday 23:59). RESULTS: The median age was 61 years (interquartile range 49-70) and 69.6% (n = 222) were male. Almost 50% (n = 149) of patients presented in a critical preoperative state. Forty-one percent of patients (n = 131) underwent night-time surgery. There were no differences in baseline data, time from onset of symptoms to surgery or surgical treatment between groups, except from preferred femoral access for arterial cannulation during night-time. Advanced age [odds ratio 1.042, 95% confidence interval (CI) 1.014-1.070], preoperative malperfusion syndrome (odds ratio 2.542, 95% CI 1.279-5.051) and preoperative tamponade (odds ratio 2.562, 95% CI 1.215-5.404) emerged as risk factors for 30-day mortality. Night-time or weekend surgery did not have any impact on 30-day mortality when covariates were considered. CONCLUSIONS: Based on the natural course of the disease and our results, surgery for type A aortic dissection should be performed as an emergency surgery regardless of time and day.

BACKGROUND: Neurologic dysfunction remains an ongoing challenge in the diagnosis of type A aortic dissection (AAD). Our study analyzed the impact of preoperative neurologic dysfunction (PND) on outcome and assessed a potential link between PND and specific patterns of postoperative neurologic injury. METHODS: Medical records of 338 patients (70.1% men; mean age, 59.3 ± 13.7 years) undergoing surgical repair for AAD were screened for the presence of PND. Preoperative characteristics, surgical treatment, and hospital and neurologic outcomes were analyzed according to patients with PND (PND+) and without PND (PND-) RESULTS: There were 50 patients (14.8%) admitted with PND. PND+ patients showed significantly higher rates of postoperative neurologic injury (44.4%) than PND- patients (14.3%; P < .001) with a specific pattern of ischemic lesions in accordance with preoperative neurologic status. While PND+ patients suffered mainly from right hemispheric strokes (66.7% vs 32.4% in PND- patients, P = .024), PND- patients more frequently presented with bilateral cerebral ischemia (56.8% vs 13.3% in PND+ patients, P = .004). Multivariable analysis identified presence of PND (odds ratio, 2.977; 95% confidence interval, 1.357-6.545) as an independent predictor for new postoperative neurologic injury. PND was associated with impaired survival (P = .005). CONCLUSIONS: This study identified an association of preoperative neurologic status and specific stroke patterns after surgical repair of AAD. Irrespective of timing of surgery and reperfusion strategies, preoperative neurologic dysfunction is strongly associated with impaired neurologic outcome.

BACKGROUND: Outcome data of patients with acute myocardial infarction (AMI)-induced cardiogenic shock (CS) receiving extracorporeal life support (ECLS) are sparse. METHODS: A consecutive series of 106 patients with AMI-induced CS receiving ECLS was evaluated regarding ECLS weaning success, hospital mortality, and long-term outcome. The Intraaortic Balloon Pump in Cardiogenic Shock II (IABP-SHOCK II) risk score was applied, and multivariable Cox regression analysis was performed. RESULTS: Mean patient age was 58.2 ± 11.2 years, and 78.3% were men. In 34 patients (32.1%), ECLS was implemented during ongoing cardiopulmonary resuscitation. De novo AMI was present in 58 patients (54.7%), and percutaneous coronary intervention complications were causative among 48 patients (45.3%). Multivessel coronary artery disease was diagnosed among 73.6% with mean Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) scores of 30.8 ± 4.8. Actuarial survival was 54.4% at 30 days, 42.2% at 1 year, and 38.0% at 5 years and was significantly higher among patients with low and intermediate IABP-SHOCK II risk scores at ECLS onset (log-rank P = .017). ECLS weaning with curative intention after a mean perfusion time of 6.6 ± 5.1 days was feasible in 51 patients (48.1%) and more likely among patients with complete revascularization (P = .026). Multivariable Cox regression analysis identified complete revascularization (hazard ratio, 2.38; 95% confidence interval, 1.1 to 5.1; P = .028) and absence of relevant mitral regurgitation at ECLS discontinuation (hazard ratio, 2.71; 95% confidence interval, 1.2 to 6.0; P = .014) to be associated with beneficial long-term survival after ECLS discontinuation. CONCLUSIONS: Emergency ECLS is a valuable option among patients with AMI-induced CS with low and intermediate IABP-SHOCK II risk scores. ECLS weaning is manageable, but additional revascularization of all nonculprit lesions is mandatory after ECLS implementation.

OBJECTIVES: This study sought to assess the incremental prognostic value of the psoas muscle area in patients scheduled for transcatheter aortic valve implantation (TAVI). METHODS: A total of 1076 consecutive patients undergoing TAVI at 2 centres between 2010 and 2017 were prospectively included in this study. Computed tomography-derived cross-sectional area of the psoas muscle was measured at the superior border of the third (L3) and fourth (L4) lumbar vertebra and indexed to body surface area (PMAi) as well as stratified into tertiles. Multivariable logistic regression and Cox regression analyses were performed to investigate the value of PMAi as a predictor of 30-day and cumulative mortality. The incremental prognostic value of PMAi over the Society of Thoracic Surgeons (STS) score was assessed using a net reclassification analysis. RESULTS: The rate of 30-day mortality was 5.8% (n = 62). PMAi at the level of L3 [odds ratio 0.082, 95% confidence interval (CI) 0.011-0.589; P = 0.013] and L4 (odds ratio 0.049, 95% CI 0.005-0.536; P = 0.013) was independently associated with 30-day mortality. During a median follow-up of 435 days (interquartile range 139-904), 292 patients (27.1%) died. PMAi of L3 (hazard ratio 0.200, 95% CI 0.083-0.482; P < 0.001) and L4 (hazard ratio 0.083, 95% CI 0.029-0.235; P < 0.001) was independently associated with mortality during follow-up. The addition of PMAi to the STS score led to a net reclassification improvement for 30-day and cumulative mortality. CONCLUSIONS: PMAi emerged as a valuable outcome predictor in patients undergoing TAVI. The addition of PMAi to the established STS score led to an increase in its prognostic ability.

OBJECTIVE: Totally endoscopic coronary artery bypass grafting was shown to be feasible and safe, with excellent clinical and angiographic mid-term results. Data on long-term outcome are lacking. Therefore, we aimed to investigate the long-term rate of major adverse cardiac and cerebrovascular events and left internal mammary artery patency rate in patients undergoing arrested heart totally endoscopic coronary artery bypass grafting. METHODS: From 2001 to 2012, a total of 208 arrested heart-totally endoscopic coronary artery bypass grafting patients were prospectively included. Mean ± SD age was 58.8 ± 9.4 years, and mean ± SD Society of Thoracic Surgeons score was 0.5 ± 0.5%. Major adverse cardiac and cerebrovascular events were defined as a composite of death, myocardial infarction, stroke, re-percutaneous coronary intervention, re-coronary artery bypass graft, and target vessel revascularization. Left internal mammary artery patency was assessed using cardiac computed tomography and depicted according to the established Fitzgibbon classification. Mean ± SD follow-up was 6.9 ± 2.3 years. RESULTS: At 1, 5, and 10 years, survival rate was 100%, 98.3%, and 95.8%, respectively. The freedom from clinical events at 1, 5, and 10 years were major adverse cardiac and cerebrovascular events (93.5%, 85.9%, and 83.0%), myocardial infarction (99.0%, 97.4%, and 95.9%), target vessel revascularization (96.0%, 94.3%, and 91.7%), re-percutaneous coronary intervention (94.5%, 91.6%, and 84.2%), and re-coronary artery bypass graft (100%, 99.5%, and 99.5%), respectively. Left internal mammary artery patency rate at 1, 5, and 10 years was 100%, 94.9%, and 88.1%, respectively. CONCLUSIONS: Arrested heart-totally endoscopic coronary artery bypass grafting shows excellent clinical long-term results with a left internal mammary artery patency rate comparable with conventional coronary artery bypass graft at 10 years after surgery.
