Background Transcatheter aortic valve replacement (TAVR) has become an established alternative to surgical aortic valve replacement (AVR) for higher risk patients. Periprocedural TAVR complications decreased with a growing expertise of implanters. Yet, TAVR can be accompanied by life-threatening adverse events such as intraprocedural cardiopulmonary resuscitation (CPR). This study retrospectively analyzed predictors and outcomes in a cohort of patients from a high-volume center undergoing periprocedural CPR during TAVR. Methods A total of 729 patients undergoing TAVR, including 59 with intraprocedural CPR, were analyzed with respect to peri- and postprocedural outcomes. Results Patients undergoing CPR showed a significantly lower left ventricular ejection fraction (LVEF) and lower baseline transvalvular mean and peak pressure gradients. The systolic blood pressure measured directly preoperatively was significantly lower in the CPR cohort. CPR patients were in a higher need for intraprocedural defibrillation, heart-lung circulatory support, and conversion to open heart surgery. Further, they showed a higher incidence of atrioventricular block grade III , valve malpositioning, and pericardial tamponade. The in-hospital mortality was significantly higher after intraprocedural CPR, accompanied by a higher incidence of disabling stroke, new pacemaker implantation, more red blood cell transfusion, and longer stay in intensive care unit. Conclusion Impaired preoperative LVEF and instable hemodynamics before valve deployment are independent risk factors for CPR and are associated with compromised outcomes. Heart rhythm disturbances, malpositioning of the prosthesis, and pericardial tamponade are main causes of the high mortality of 17% reported in the CPR group. Nevertheless, mechanical circulatory support and conversion to open heart surgery reduce mortality rates of CPR patients.

The outcomes of patients with PCS and following ECMO therapy are associated with several preoperative risk factors. Our aim was to compare clinical presentation, ECMO-related data and in-hospital outcomes of patients treated with ECMO due to PCS after cardiac surgery, in regard to elective or emergent cardiac surgery procedures. Between April 2006 and October 2016, 164 consecutive patients that received VA-ECMO therapy due to PCS were identified and included in this retrospective cohort study. The patients were divided into groups based on the urgency of the initial procedures performed: elective group (ELG; n = 95) and an emergency group (EMG; n = 69). To compare the unequal patient groups, a propensity score-based matching (PSM) was applied (ELG, n = 56 vs. EMG, n = 56). The EMG primarily received ECMO intraoperatively (p <= 0.001). In contrast, the ELG were needed ECMO support more frequently postoperatively (p < 0.001). In-hospital mortality accounted for 71% (n = 40) in the ELG and 76% (n = 43) in the EMG (p = 0.518). Outcome data showed no major differences in the (abdominal ischemia (p = 0.371); septic shock (p = 0.393): rhythm disturbances (p = 0.575); emergency re-thoracotomy (p = 0.418)) between the groups. The urgency of the initial procedures performed is secondary in patients suffering PCS and following ECMO. In this regard, PCS itself seems to trigger outcomes in cardiac surgery ECMO patients substantially.

Background Prognosis of patients with end-stage heart failure is known to be impacted by the aetiology of heart failure (HF). Ischaemic cardiomyopathy (ICM) and dilated cardiomyopathy (DCM) are the most frequent pa-thologies necessitating ventricular assist device (VAD) support in these patients. However, the specific impact of ICM and DCM in clinical outcomes after VAD implantation remains unclear. Therefore, this study aimed to analyse clinical differences in ICM and DCM patients after LVAD surgery from the current institution. Methods All consecutive patients from the LVAD centre were included in this retrospective study. To analyse specific differences in in-hospital outcomes, patients were divided into two groups: ICM and DCM. Long -term follow-up was calculated by Kaplan-Meier estimation of survival. Results Between January 2010 and July 2020, 60 consecutive patients underwent LVAD implantation at the insti-tution: 36 patients (60%) were supported due to end-stage ICM and 24 patients (40%) in regard of therapy-refractory DCM. Baseline characteristics showed no between-group differences. The ICM patients showed a clear trend to higher amount of additional cardiac procedures during VAD surgery (36% ICM vs 12% DCM; p=0.052). In-hospital mortality was comparable between ICM and DCM patients (36% ICM vs 21% DCM; p=0.206). A trend towards higher frequency of pump thrombosis was seen in DCM patients (p=0.080). Long-term survival was comparable between the groups. Conclusion The aetiology of heart failure did not impact short-term or long-term clinical outcomes after VAD surgery. Multicentre registry data are necessary to substantiate these findings.

Introduction Cardiac tumors represent a rare and heterogenous pathologic entity, with a cumulative incidence of up to 0.02%. This study aimed to investigate one of the largest patient cohorts published for clinical presentation and long-term outcomes after surgical resection. Areas covered Between 2009 and 2021, 183 consecutive patients underwent surgery for tumor excision in our center. Preoperative baseline characteristics, intraoperative data, and long-term survival were analyzed. The diagnosis was confirmed postoperatively by histology and Immunohistochemical investigations. Kaplan-Meier curves assessed survival, and the Cox proportional hazards model, was used to identify prognostic factors for overall survival. Results This series included 183 consecutive patients; most (n = 169, 92.3%) were diagnosed with benign cardiac masses. The mean age of patients was 60 +/- 16 years, and 48% (n = 88) were females. The largest group of tumors was myxoma (n = 98; 54%). The most common malignant tumor type was sarcoma (n = 5; 2.7%). The mean hospital stay was 11 +/- 6.5 days, and all-cause mortality after ten years was 14%. Expert Opinion Surgery represents the gold standard in treating primary cardiac tumors; in benign tumors, it is highly effective and curative, whereas, in malignant tumors, it remains associated with more prolonged survival.

Objectives Extracorporeal membrane oxygenation or extracorporeal life support (ECLS) in patients after cardiac surgery and postcardiotomy cardiogenic shock (PCS) is known to be associated with high mortality. Especially in patients after coronary artery bypass grafting (CABG) and PCS, ECLS is frequently established. The aim of this analysis was to evaluate factors associated with in-hospital mortality in patients treated with ECLS due to PCS after CABG. Methods Between August 2006 and January 2017, 92 consecutive patients with V-A ECLS due to PCS after isolated CABG were identified and included in this retrospective analysis. Patients were divided into survivors (S) and non-survivors (NS) and analyzed with risk factors of in-hospital mortality. Results In-hospital mortality added up to 61 patients (66%). Non-survivors were significantly older (60 +/- 812 (S) vs. 67 +/- 10 (NS); p = 0.013). Bilateral internal mammary artery graft was significantly more frequently used in S (23% (S) vs. 2% (NS); p = 0.001). After 24 h of ECLS support, median lactate levels were significantly higher in NS (1.9 (1.3; 3.5) mmol/L (S) vs. 3.5 (2.1; 6.3) mmol/L (NS); p = 0.001). NS suffered more often acute kidney injury requiring dialysis (42% (S) vs. 74% (NS); p = 0.002). Conclusion Mortality in patients with refractory PCS after CABG and consecutive ECLS support remains high. Failing end-organ recovery under ECLS despite optimized concomitant medical therapy is an indicator of adverse outcomes in this specific patient cohort. Moreover, total-arterial revascularization might be beneficial for cardiac recovery in patients suffering PCS after CABG and following ECLS.

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) represents an increasingly used method for circulatory support. Despite the ongoing research, survival following VA-ECMO therapy remains low. Sex-related differences might impact the outcome of therapeutic measures. We aimed to compare all-cause mortality among female and male patients who underwent VA-ECMO as a bridge to recovery investigating sex-related differences. From January 2015 until August 2020, 87 patients were supported by VA-ECMO as a part of our out-of-center mobile ECMO program. In order to analyze sex-associated differences in early clinical outcomes, patients were divided into two sex categories: men (n = 62) and women (n = 25). All relevant data (in-hospital mortality, ICU and hospital stay, renal failure requiring dialysis, lung failure, bleeding, stroke and septic shock) were analyzed retrospectively after the extraction from our institutional database. Mean age of the study population was 53 +/- 14 years. Mean EuroSCORE II predicted mortality was 6.5 +/- 3.7. In-hospital mortality rate was not significantly lower in the female group (58.3%) vs. the male group (71.2%), p = 0.190. The mean length of ICU and hospital stay was 9 +/- 11 in the male group vs. 10 +/- 13 in the female group, p = 0.901, and 10 +/- 12 (male group) vs. 11 +/- 13 (female group), p = 0.909, respectively. Renal failure requiring hemodialysis (36.2% (males) vs. 28.6% (females), p = 0.187) was comparable between both groups. Respiratory failure was diagnosed in 31 (56.4%) male vs. 8 (34.8%) female patients, p = 0.068, while 16 (28.6%) male vs. 3 (13.0%) female patients (p = 0.118) suffered from septic shock. Based on our data, there were no sex-specific outcome discrepancies in patients treated with mobile VA-ECMO implantation.

Deep sternal wound infection (DSWI) is a feared complication after cardiac surgery. The impact of sex-related differences on wound infection prevalence is poorly understood. Our aim was to evaluate the effect of sex on short-term outcomes in patients with DSWI after open-heart surgery. The study was a retrospective cohort study. A total of 217 patients with DSWI were identified and retrospectively analyzed using our institutional database. Patients were divided into two groups: males (n = 150) and females (n = 67). This study also includes a propensity score based matching (PSM) analysis (male group (n = 62) and female group (n = 62)) to examine the unequal groups. Mean age (p = 0.088) and mean body mass index (BMI) (p = 0.905) did not significantly differ between both groups. Vacuum assisted closure (VAC) therapy was performed among most patients (82.3% (male group) vs. 83.9% (female group), p = 0.432). The most commonly isolated bacteria from the wounds were Staphylococcus epidermidis and Staphylococcus aureus in both groups. Acute renal failure was significantly higher (p = 0.010) in the male group compared to the female group. However, dialysis rate did not significantly differ (p = 0.491) between male and female groups. Further secondary outcomes showed no major differences between the groups. Likewise, in-hospital mortality rate did not differ significantly (p = 0.680) between both groups. Based on our data, sex has no impact on deep wound infection prevalence after cardiac surgery.

Recent advances in perioperative care have considerably improved outcomes after coronary artery bypass graft (CABG) surgery. However, obesity can increase postoperative complication rates and can lead to increased morbidity and mortality. Between June 2011 and October 2019, a total of 1375 patients with acute coronary syndrome (ACS) underwent cardiac surgery and were retrospectively analyzed. Patients were divided into 2 groups: non-obese (body mass index (BMI) < 30 kg/m(2), n = 967) and obese (BMI >= 30 kg/m(2), n = 379). Underweight patients (n = 29) were excluded from the analysis. To compare the unequal patient groups, a propensity score-based matching (PSM) was applied (non-obese group (n = 372) vs. obese group (n = 372)). The mean age of the mentioned groups was 67 +/- 10 (non-obese group) vs. 66 +/- 10 (obese group) years, p = 0.724. All-cause in-hospital mortality did not significantly differ between the groups before PSM (p = 0.566) and after PSM (p = 0.780). The median length of ICU (p = 0.306 before PSM and p = 0.538 after PSM) and hospital stay (p = 0.795 before PSM and p = 0.131 after PSM) was not significantly higher in the obese group compared with the non-obese group. No significant differences regarding further postoperative parameters were observed between the unadjusted and the adjusted group. Obesity does not predict increased all-cause in-hospital mortality in patients undergoing CABG procedure. Therefore, CABG is a safe procedure for overweight patients.

Objectives Cardiac tumors represent a rare and heterogeneous pathological entity, with a cumulative incidence of up to 0.02%. Gender was previously reported to influence outcomes after tumor surgery. This study aimed to investigate for gender-related differences in outcomes after cardiac surgery. Methods Between 2009 and 2021, 95 male and 88 female patients underwent surgery for tumor extirpation in our center. Preoperative baseline characteristics, intraoperative data, and long-term survival were analyzed. The diagnosis was confirmed postoperatively by (immune-)histopathological analysis. Results There were no significant differences in baseline characteristics and survival. Myxoma was the most common tumor type overall and was more diagnosed in women (n = 36 vs. n = 62, p <= 0.001). Sarcoma was the most common malignant tumor type (n = 5). Tumor location at the atrial septum was more likely in women (n = 26 vs. n = 16, p = 0.041), whereas ventricular localization was more common in male patients (n = 20 vs. n = 7, p = 0.001). Minimally invasive tumor extirpation was significantly more often performed in women, and in-hospital stay was shorter in female patients. Conclusion The localization and dignity of cardiac tumors differ between genders, not affecting survival. Surgical tumor extirpation remains the gold standard of treatment for cardiac tumors in both genders as it is highly effective and associated with good long-term survivorship.

Aims: Oral anticoagulation with direct oral anticoagulants (DOAC) could provide an alternative to vitamin K antagonists (VKA) for patients with atrial fibrillation (AF) undergoing bioprosthetic heart valve replacement or valve repair. Methods and results: The aim of this meta-analysis was to review the safety and efficacy of DOAC in patients with surgical implanted bioprosthetic heart valves or valve repairs and AF including data from six clinical trials with a total of 1,857 patients. The efficacy and safety data of DOAC and VKA were pooled to perform random-effects meta-analyses using the Mantel-Haenszel method with pooled risk ratios (RR) and 95% confidence interval (CI). A trial sequential analysis (TSA) was performed to assess statistical robustness. Death caused by cardiovascular cause or thromboembolic events were comparable (RR 0.67, 95% CI: 0.42-1.08; p= 0.101 as DOAC significantly reduced the risk for major bleeding (RR 0.55, 95% CI: 0.35-0.88; p = 0.01) and thromboembolic stroke or systemic embolism rates (RR 0.54, 95% CI: 0.32-0.90; p= 0.021. Rates for intracranial bleeding and hemorrhagic stroke (RR 0.27, 95% CI: 0.07-0.99; p= 0.051 show a trend toward fewer events in the DOAC group. Outcomes for major or minor bleeding events and all-cause mortality were comparable for DOAC and VKA. Conclusion: Cumulative data analysis reveals that DOAC may provide an effective and safe alternative to VKA in patients with AF after surgically implanted bioprosthetic heart valves or repair with AF. Within a relatively heterogeneous study population, this meta-analysis shows a risk reduction of major bleedings and thromboembolic stroke or systemic embolisms for DOAC.

Background Percutaneous edge-to-edge mitral valve repair technique (MitraClip) is a widely used treatment for mitral regurgitation (MR) in patients assessed with high surgical risk or inoperability. Only limited experiences with this highest-risk patient population exist. Procedural failure for MitraClip or recurrent MR is a strong predictor of 1-year mortality. Open mitral valve surgery constitutes the last bailout for patients within this cohort. Methods This retrospective single-center cohort study analyzed 17 mitral valve surgery patients after failed MitraClip. We, therefore, analyzed a high-risk patient population (EuroSCORE II = 10 +/- 2.0) with persistent mitral valve regurgitation, which was mainly caused by detachment or dislocation of the MitraClip. Results Symptomatic patients with failed MitraClip need a convenient operation (mean time to mitral valve surgery = 23 +/- 44 days). The patient's collective showed many complex reoperations with the need for concomitant surgery. Considering the high-risk patient population, we showed an average 30-day all-cause mortality (18%, n = 3) accompanied by typical postoperative complications related to prolonged mechanical ventilation (44 +/- 48 h) and ICU stay (11 +/- 11 days), reflecting high-risk patients. Further, excellent valve-related outcomes were shown regarding adverse cardiac events (valve-related mortality 6%, n = 1) and postoperative echocardiographic results (moderate or severe paravalvular leak 6%, n = 1). Conclusion Failure of MitraClip represents a challenging situation limited by high-risk profiles of patients and limits the possibility of surgical valve repair, shown by a high rate of mitral valve replacement (94%, n = 16). Secondary surgery was associated with moderate 30-day and postdischarge outcomes. Therefore, a careful evaluation of patients undergoing MitraClip is of paramount importance.

Background Obesity is known to impact outcomes of patients undergoing in-patient care in general. The association between veno-arterial extracorporeal membrane oxygenation (VA ECMO) and obesity-related outcomes remains unclear. Therefore, we sought to investigate weight-associated differences of patients treated with VA ECMO. Method A retrospective study was performed for patients who required veno-arterial (VA) ECMO support at our tertiary ECMO centre between 1 March 2006 and 28 February 2017. Patients were categorised according to Body-Mass-Index (BMI) associated values in six groups (underweight, normal range, overweight, obese class I-III). Further, patients were divided into non-obese (18.5-29-9 kg/m(2)) and obese (>= 30 kg/m(2)) groups and analysed concerning baseline, ECMO-related, and general outcome parameters. Results A total of 244 patients required VA ECMO support during the study period. Subgroup-analysis of BMI-category associated impact on in-hospital mortality showed the highest incidence of mortality in obese class II patients (93%) with a significant difference between overweighted patients. Non-obesity was present in 179, whereas 59 patients suffered obesity. Obese patients were significantly older (p=0.022) and suffered significantly more diabetes (21% non-obese vs 48% obese; p,0.001). Indication for support, laboratory parameters prior to ECMO, and ECMO-related outcomes did not differ between the groups. Obese patients showed a trend towards higher in-hospital mortality (70% non-obese vs 81% obese; p=0.085). Conclusions Obesity is associated with comparable outcomes to non-obese patients, showing a tendency of higher mortality. Obese class II patients presented the highest risk of death compared to all BMI categories.

(1) Introduction: Simultaneous ECMO and IABP therapy is frequently used. Haemodynamic changes responsible for the success of the concomitant mechanical circulatory support system approach are rarely investigated. In a large-animal model, we analysed haemodynamic parameters before and during ECMO therapy, comparing central and peripheral ECMO circulation with and without simultaneous IABP support. (2) Methods: Thirty-three female pigs were divided into five groups: (1) SHAM, (2) (peripheral)ECMO(-)IABP, (3) (p)ECMO(+)IABP, (4) (central)ECMO(-)IABP, and (5) (c)ECMO(+)IABP. Pigs were cannulated in accordance with the group and supported with ECMO (+/- IABP) for 10 h. Systemic haemodynamics, cardiac index (CI), and coronary and carotid artery blood flow were determined before, directly after, and at five and ten hours on extracorporeal support. Systemic inflammation (IL-6; IL-10; TNF alpha; IFN gamma), immune response (NETs; cf-DNA), and endothelial injury (ET-1) were also measured. (3) Results: IABP support during antegrade ECMO circulation led to a significant reduction of left ventricular pressure in comparison to retrograde flow in (p)ECMO(-)IABP and (p)ECMO(+)IABP. Blood flow in the left anterior coronary and carotid artery was not affected by extracorporeal circulation. (4) Conclusions: Concomitant central ECMO and IABP therapy leads to significant reduction of intracavitary cardiac pressure, reduces cardiac work, and might therefore contribute to improved recovery in ECMO patients.

Background Rapid deployment aortic valve replacement (RDAVR) and transcatheter aortic valve implantation (TAVI) have emerged as increasingly used alternatives to conventional aortic valve replacement to treat patients at higher surgical risk. Therefore, in this single-center study, we retrospectively compared clinical outcomes and hemodynamic performance of two self-expanding biological prostheses, the sutureless and rapid deployment valve (RDV) Perceval-S (PER) and the transcatheter heart valve (THV) ACURATE neo /TF (NEO) in a 1:1 propensity-score-matching (PSM) patient cohort. Methods A total of 332 consecutive patients with symptomatic aortic valve stenosis underwent either singular RDAVR with PER (119) or TAVI with NEO (213) at our institutions between 2012 and 2017. To compare the unequal patient groups, a 1:1 PSM for preoperative data and comorbidities was conducted. Afterward, 59 patient pairs were compared with regard to relevant hemodynamic parameter, relevant paravalvular leak (PVL), permanent postoperative pacemaker (PPM) implantation rate, and clinical postoperative outcomes. Results Postoperative clinical short-term outcomes presented with slightly higher rates for 30-day all-cause mortality (PER=5.1% vs. NEO=1.7%, p =0.619) and major adverse cardiocerebral event in PER due to cerebrovascular events (transient ischemic attack [TIA]-PER=3.4% vs. TIA-NEO=1.7%, p =0.496 and Stroke-PER=1.7% vs. Stroke-NEO=0.0%, p =1). Moreover, we show comparable PPM rates (PER=10.2% vs. NEO=8.5%, p =0.752). However, higher numbers of PVL (mild-PER=0.0% vs. NEO=55.9%, p =0.001; moderate or higher-PER=0.0% vs. NEO=6.8%, p =0.119) after TAVI with NEO were observed. Conclusion Both self-expanding bioprostheses, the RDV-PER and THV-NEO provide a feasible option in elderly and patients with elevated perioperative risk. However, the discussed PER collective showed more postoperative short-term complications with regard to 30-day all-cause mortality and cerebrovascular events, whe

OBJECTIVES: The German Registry of Acute Aortic Dissection Type A (GERAADA) score to predict 30-day mortality in patients suffering from acute aortic dissection type A (AADA) was recently introduced. The aim of this study was to evaluate if the GERAADA score's prediction corresponds with the authors' institutional results. METHODS: All consecutive AADA patients between 2010 and 2020 were included. Retrospective data collection comprised 11 preoperative parameters: age, sex, previous cardiac surgery, inotropic support at referral, resuscitation before surgery, aortic regurgitation, preoperative hemiparesis, intubation/ventilation at referral, preoperative organ malperfusion, extension of aortic dissection and location of primary entry site. Calculations of the GERAADA score were individually performed by a cardiac surgeon blinded to the study for all patients via a web-based application (https://www.dgthg.de/de/GERAADA_Score). RESULTS: A total of 371 AADA patients were operated at the authors' institution. The mean age was 62.7 +/- 13.5 years and 233 (63%) were males. Prediction of 30-day mortality was accurate for the entire study cohort (actual vs predicted 30-day mortality: 15.1% vs 15.7%; P = 0.776) as well as for all 26 subgroups. In addition, preoperative resuscitation (P < 0.001), advanced age (P = 0.042) and other/unknown malperfusion (P = 0.032) were identified as independent risk factors. CONCLUSIONS: The GERAADA score prediction of 30-day mortality after surgery is accurate, easily accessible due to its web-based platform and can be calculated with very basic preoperative clinical parameters. A prospective clinical trial is required to further evaluate the new GERAADA score as a useful tool to allow for improved decision-making in the emergency setting of AADA.

Objectives Simultaneous mechanical circulatory support (MCS) with intra-aortic balloon pump (IABP) to extracorporeal membrane oxygenation (ECMO) is common in postcardiotomy cardiogenic shock (PCS). This study aimed to analyse the effect of concomitant ECMO and IABP therapy on the short-term outcomes of patients with PCS. Methods Between March 2006 and March 2017, 172 consecutive patients with central (c) or peripheral (p) venoarterial ECMO therapy due to PCS were identified at the current institution and included in this retrospective analysis. Patients were divided into ECMO+IABP and ECMO alone groups. Further, the impact of ECMO flow direction was analysed for the groups. Results A total of 129 patients received ECMO+IABP support and 43 patients were treated with ECMO alone. Median ECMO duration did not differ between the groups (68 [34; 95] hours ECMO+IABP vs 44 [20; 103] hours ECMO; p=0.151). However, a trend toward a higher weaning rate was evident in ECMO+IABP patients (75 [58%] ECMO+IABP vs 18 [42%] ECMO; p=0.078). Concomitant IABP support with either cECMO (73% [n=24] cECMO+IABP vs 50% [n=11] ECMO; p=0.098) or pECMO (57% [n=55] ECMO+IABP vs 33% [n=7] ECMO; p=0.056) was also associated with a trend toward a higher weaning rate off ECMO. In-hospital mortality did not differ between the groups. Conclusion This analysis found that, independent of ECMO type, additional IABP support might increase ECMO weaning; however, it did not influence survival in PCS patients. Larger studies are necessary to further analyse the impact of this concomitant MSC therapy on clinical outcomes.

Background Extracorporeal cardiopulmonary resuscitation (eCPR) is an established treatment option for cardiac arrest. Mechanical reanimation devices are increasingly used but have been associated with complications. This study evaluates typical injury patterns and differences after mechanical versus manual chest compressions among patients undergoing eCPR. Methods From 2016 to 2020, 108 eCPR patients were retrospectively analyzed. Primary endpoints were traumatic, hemorrhagic, or inner organ-related complications, defined as pneumothorax, pulmonary bleeding, major bleeding, gastrointestinal bleeding, gastrointestinal ischemia, cardiac tamponade, aortic dissection, sternal or rib fracture. Results 70 patients were treated with mechanical CPR (mCPR) and 38 with conventional CPR (cCPR). There were more CPR-related injuries in the mCPR group (55% vs. 83%, p = 0.01), CPR duration was longer (cCPR 40 +/- 28 min vs. mCPR 69 +/- 25 min, p = 0.01). There was no significant difference in mortality between the groups. Conclusion Mechanical CPR devices are associated with a higher incidence of traumatic and hemorrhagic injuries in patients undergoing eCPR.

Introduction Over the last decade, eCPR programs have become more and more popular, at least amongst high-volume centers. Despite its rise in popularity and promising outcome, strategies concerning pre- and post-implantation of VA-ECMO remain at least debatable. Besides, integrating the appropriate set-up, managing anticoagulation, implementing LV-venting, and predicting neurological outcome play important roles in caring for thise highly selective patient-collective. We sought to present our institutional ' s techniques for establishing an eCPR program and managing patients peri- and post implantation in eCPR-runs. Areas covered This manuscript covers the majority of clinical concerns and parameters for establishing an eCPR program and its recent advantages. We will describe a safe way of cannulation, setting anticoagulation goals, strategies for LV-venting and ICU-treatment. Also included, an elaboration on neurological and cardiac prognostication Expert Opinion We advocate ultrasound-guided cannula placement in eCPR patients. Also, we emphasize the importance of using stiffer wires and smaller arterial cannula sizes due to the different physiological parameters of OHCA patients. After cannulation, we aim for lower flow goals, the concept of 'partial VA-ECMO,' and lower anticoagulatory targets. LV-venting with Impella should remain an individual case to case decision.

Pulmonary embolism can be associated with paradox embolism requiring immediate surgical therapy regardless of hemodynamic status. Here we present images illustrating a giant transit thrombus as a concomitant finding in a patient with pulmonary artery embolism.

Objective Patients with acute coronary syndrome are treated with dual antiplatelet therapy containing acetylsalicylic acid (ASA) and P2Y12 antagonists. In case of urgent coronary artery bypass grafting this might be associated with increasing risks of bleeding complications. Methods Data from 1200 consecutive urgent operations between 2010 and 2018 were obtained from our institutional patient database. For this study off-pump surgery was excluded. The primary composite end point major bleeding consisted of at least one end point: transfusion >= 5 packed red blood cells within 24hours, rethoracotomy due to bleeding, chest tube output >2000mL within 24hours. Demographic data, peri-, and postoperative variables and outcomes were compared between patients treated with mono antiplatelet therapy, ASA+clopidogrel (ASA-C) +ticagrelor (ASA-T) or +prasugrel (ASA-P)<72hours before surgery. Furthermore, we compared patients with dual antiplatelet therapy with ASA monotherapy. Results From 1,086 patients, 475 (44%) received dual antiplatelet therapy. Three-hundred seventy-two received ASA-C (77.7%), 72 ASA-T (15%), and 31 ASA-P (6.5%). Major bleeding (44 vs. 23%, p <0.0001) was more frequently in patients receiving dual therapy with higher rates of massive drainage loss within 24hours (23 vs. 11%, p <0.0001) of mass transfusion (34 vs. 16%, p <0.0001) and rethoracotomy (10 vs. 5%, p =0.002) when compared with ASA. In this analysis, ASA-T and ASA-P were not associated with higher bleeding complications compared with ASA-C. Conclusion Dual antiplatelet therapy is associated with higher rates of major bleeding. Further studies should examine the difference in the prevalence of major bleeding complications in the different dual antiplatelet therapy regimes in patients requiring urgent surgery.

Pericardial cysts are rare, abnormal, benign and usually congenital anomalies with an estimated incidence of 1:100.000 and are caused by an incomplete coalescence of foetal lacunae of pericardium development. The size of pericardial cysts varies from 1 to 5 cm and generally do not cause any symptoms. Pectus excavatum is one of the most frequent chest wall abnormalities with a caved-in appearance of the chest and mostly of unknown pathogenesis. We present a rare case of constrictive pericarditis with a huge pericardial cyst (11.6 x 8.7 x 7.1 cm) and pectus excavatum which led to compression of the heart and life-threatening cardiac arrhythmias.

Background Primary cardiac tumors are rare, andmany diagnosed tumors are benign with an incidence of 0.001% to 0.03%. The primary angiosarcoma is one of the malignant entities. Discussion We discuss a case report of a 76-year-old male who underwent a preoperative diagnosis for an upcoming shoulder operation when his cardiologist diagnosed a large cardiac tumor. The patient was referred to our department where he received further diagnostics. The transesophageal echocardiography and the cardiac-magnetic resonance imaging showed a massive tumor with a dimension of 8.6 x 5.6 cm with no signs of malignity. Method The operation was performed by standard median sternotomy. The tumor was adherent to the septum and the left atrium, and we were able to remove the specimen in toto. Pathological examinations showed an angiosarcoma with neovascularization and core expression of ERG+ and cytoplasmic expression of CD31+/CD34+, due to the size of the mass. The resection of primary cardiac tumors is mostly the therapy of choice, but in this case concerning an angiosarcoma the prognosis is poor, considering that the angiosarcoma responds very badly to chemotherapy and radiotherapy.

OBJECTIVES: Rapid-deployment aortic valve replacement (RD-AVR) potentially reduces procedure times providing excellent haemodynamic results compared to standard tissue aortic valve replacement. However, concerns have been raised regarding higher rates of postoperative pacemaker (PPM) requirement compared to standard aortic valve replacement. In this study, we sought to determine the PPM rate and its potential risk factors in RD-AVR patients. METHODS: Between 2011 and 2017, 193 patients underwent RD-AVR. The main outcome investigated was PPM. Other outcome parameters included hospital mortality, major morbidity, length of stay and discharge condition. Predictors of PPM were determined using multivariable regression models. RESULTS: Isolated RD-AVR was performed in 72 (37%) patients and 121 (63%) patients underwent combined RD-AVR [coronary artery bypass grafting (n = 110), mitral repair (n = 6) and others (n = 5)]. Aortic cross-clamp and cardiopulmonary bypass times were 57.1 +/- 25.1 min and 90.0 +/- 40.1 min in the overall RD-AVR population and 39.4 +/- 13.5 min and 67.6 +/- 24.5 min, respectively, in isolated RD-AVR procedures. PPM occurred in 20 (10.4%) patients. Multivariable analysis revealed bypass grafting of the circumflex artery [odds ratio = 2.8] and preoperative right branch bundle block (odds ratio = 11.7) as independent predictors for PPM. CONCLUSIONS: RD-AVR is a safe and simple procedure resulting in favourable short aortic cross-clamp and cardiopulmonary bypass times and considerable low gradients in postoperative echocardiography. PPM following isolated RD-AVR remains in the range of standard aortic valve replacement However, patients undergoing concomitant coronary artery bypass grafting, particularly of the circumflex artery, face a 3-fold increased risk for PPM implantation enhanced if right branch bundle block is present Follow-up examination is necessary to determine whether these patients remain pacer dependent during long-term follow-up.
