Percutaneous axillary extracorporeal membrane oxygenation supported complex left main bifurcation percutaneous coronary intervention.

A 66-year-old man with multiple comorbidities including severe peripheral artery disease and heart failure with reduced ejection fraction presented with complex coronary artery disease with an elevated Society of Thoracic Surgeons Predicted Risk of Mortality for coronary artery bypass grafting and a Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score of 18. With a multidisciplinary heart team approach, the patient successfully underwent percutaneous axillary venoarterial extracorporeal membrane oxygenation (VA-ECMO) supported high-risk percutaneous coronary intervention of a heavily calcified left main bifurcation lesion. Given the patient's peripheral artery disease, alternative arterial access for ECMO cannulation was performed percutaneously via the right axillary artery. Additionally, adequate coronary calcium modification was critical to successful stenting of a heavily calcified left main bifurcation. This case highlights a novel approach to obtaining alternative arterial access for ECMO cannulation and emphasizes the importance of calcium modification to achieve excellent stent results.

"Piggyback Pigtails": Simplifying secondary transradial access for TAVR.

Minimalist approaches have evolved for TAVR over the last years with impact on in-hospital stay and patient safety. As part of this concept, transradial secondary arterial access is capable of reducing vascular and bleeding complications. Yet, steering of the marker pigtail catheter in the descending aorta might by fluoroscopic imaging sometimes be challenging. In our manuscript, we present a very simple "piggyback" technique, simplifying management of transradial secondary access in transfemoral TAVR.

[Update on the treatment of aortic valve stenosis in symptomatic and asymptomatic patients]. / Update zur Behandlung der Aortenklappenstenose bei symptomatischen und asymptomatischen Patienten.

Aortic valve stenosis is one of the most frequent valvular heart diseases requiring treatment in industrialized countries. The symptom onset is associated with a significantly increased mortality, so that there is a clear indication for treatment in patients with severe, symptomatic aortic valve stenosis; however, data on the optimal treatment of patients with asymptomatic aortic valve stenosis are scarce. Smaller studies in the field of cardiac surgery suggest that early surgical valve replacement is superior to a conservative approach. For this reason, the results of additional adequately powered randomized trials are awaited with great interest. In this year numerous long-term results from randomized comparisons of the two available treatment options (surgical versus transcatheter aortic valve replacement) were published, which will further guide the heart team to find the best treatment approach for each individual.

2022 Joint ESC/EACTS review of the 2018 guideline recommendations on the revascularization of left main coronary artery disease in patients at low surgical risk and anatomy suitable for PCI or CABG.

In October 2021, the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) jointly agreed to establish a Task Force (TF) to review recommendations of the 2018 ESC/EACTS Guidelines on myocardial revascularization as they apply to patients with left main (LM) disease with low-to-intermediate SYNTAX score (0-32). This followed the withdrawal of support by the EACTS in 2019 for the recommendations about the management of LM disease of the previous guideline. The TF was asked to review all new relevant data since the 2018 guidelines including updated aggregated data from the four randomized trials comparing percutaneous coronary intervention (PCI) with drug-eluting stents vs. coronary artery bypass grafting (CABG) in patients with LM disease. This document represents a summary of the work of the TF; suggested updated recommendations for the choice of revascularization modality in patients undergoing myocardial revascularization for LM disease are included. In stable patients with an indication for revascularization for LM disease, with coronary anatomy suitable for both procedures and a low predicted surgical mortality, the TF concludes that both treatment options are clinically reasonable based on patient preference, available expertise, and local operator volumes. The suggested recommendations for revascularization with CABG are Class I, Level of Evidence A. The recommendations for PCI are Class IIa, Level of Evidence A. The TF recognized several important gaps in knowledge related to revascularization in patients with LM disease and recognizes that aggregated data from the four randomized trials were still only large enough to exclude large differences in mortality.

Hybrid extracorporeal cannulation for aortic root pseudoaneurysm re-operation: The role of a multidisciplinary team.

Introduction: Adequate cerebral protection for aortic reoperation is challenging and optimal technique is still controversial.Case Report: We report a hybrid cannulation approach to achieve safe cerebral protection during circulatory arrest to repair an aortic root pseudoaneurysm.Conclusion: A multidisciplinary approach combining conventional techniques and interventional expertise could be considered in complex aortic scenario.

The Challenge of Managing Atrial Fibrillation during Pregnancy.

The incidence of atrial fibrillation (AF) during pregnancy increases with maternal age and with the presence of structural heart disorders. Early diagnosis and prompt therapy can considerably reduce the risk of thromboembolism. The therapeutic approach to AF during pregnancy is particularly challenging, and the maternal and fetal risks associated with the use of antiarrhythmic and anticoagulant drugs must be carefully evaluated. Moreover, the currently used thromboembolic risk scores have yet to be validated for the prediction of stroke during pregnancy. At present, electrical cardioversion is considered to be the safest and most effective strategy in women with hemodynamic instability. Beta-selective blockers are also recommended as the first choice for rate control. Antiarrhythmic drugs such as flecainide, propafenone and sotalol should be considered for rhythm control if atrioventricular nodal-blocking drugs fail. AF catheter ablation is currently not recommended during pregnancy. Overall, the therapeutic strategy for AF in pregnancy must be carefully assessed and should take into consideration the advantages and drawbacks of each aspect. A multidisciplinary approach with a "Pregnancy-Heart Team" appears to improve the management and outcome of these patients. However, further studies are needed to identify the most appropriate therapeutic strategies for AF in pregnancy.

Protocolised Management of Cardiogenic Shock and Shock Teams: A Narrative Review.

Despite advances in therapy, the incidence of cardiogenic shock continues to increase, with significant mortality that has improved minimally over time. Treatment options for cardiogenic shock are complex and time-, resource-, and case volume-dependent, and involve multiple medical specialties. To provide early, more equitable, and standardised access to cardiogenic shock expertise with advanced therapies, cardiogenic shock teams with a protocolised treatment approach have been proposed. These processes have been applied across hospitals into integrated cardiogenic shock networks. This narrative review evaluates the role of cardiogenic shock teams, protocolised and regionalised shock networks, and the main individual components of protocolised shock management approaches.

Infective Endocarditis during Pregnancy-Keep It Safe and Simple!

The diagnosis of infective endocarditis (IE) during pregnancy is accompanied by a poor prognosis for both mother and fetus in the absence of prompt management by multidisciplinary teams. We searched the electronic databases of PubMed, MEDLINE and EMBASE for clinical studies addressing the management of infective endocarditis during pregnancy, with the aim of realizing a literature review ranging from risk factors to diagnostic investigations to optimal therapeutic management for mother and fetus alike. The presence of previous cardiovascular pathologies such as rheumatic heart disease, congenital heart disease, prosthetic valves, hemodialysis, intravenous catheters or immunosuppression are the main risk factors predisposing patients to IE during pregnancy. The identification of modern risk factors such as intracardiac devices and intravenous drug administration as well as genetic diagnostic methods such as cell-free deoxyribonucleic acid (DNA) next-generation sequencing require that these cases be addressed in multidisciplinary teams. Guiding treatment to eradicate infection and protect the fetus simultaneously creates challenges for cardiologists and gynecologists alike.

The Convergent procedure for AF: A surgeon's perspective.

The Converge IDE Trial demonstrated improved patient outcomes in a challenging persistent and long-standing persistent atrial fibrillation population using a heart team hybrid approach with epicardial and endocardial staged ablations. Surgeons encounter unique circumstances with the surgical epicardial stage of the Convergent procedure which includes unfamiliarity with left atrial posterior anatomy, endoscopic/thoracoscopic visualization, minimally invasive left atrial appendage management, and expanded indications for the procedure. Overcoming these unique challenges is key to the adoption of the Convergent procedure as a critical off-pump approach that should be part of the surgical armamentarium in the treatment of atrial fibrillation.

The impact of implementing an endocarditis team in comparison to the classic heart team in a tertiary referral centre.

BACKGROUND: Infective endocarditis (IE) is a complex disease for which the European Society of Cardiology guideline recommends a dedicated multidisciplinary endocarditis team (ET) approach since 2015. It is currently unknown whether this ET approach is beneficial compared to a classic heart team approach including bedside consultation by an infectious disease specialist in Western Europe. METHODS: This retrospective single centre, observational cohort study was conducted at the Radboudumc, a tertiary referral centre in the Netherlands. Consecutive patients treated for IE were included from September 2017 to September 2018 before implementation of a dedicated ET and from May 2019 to May 2020 afterwards. RESULTS: In total, 90 IE patients (45 patients before and 45 patients after the implementation of the ET) were included. No significant differences were found in diagnostic workup, surgical treatment (surgery performed 69% vs. 71%, p = 0.82), time to surgery because of an urgent indication (median 4 vs. 6 days, p = 0.82), in-hospital complications (53% vs. 67%, p = 0.20), and 6-month mortality (11% vs. 13%, p = 0.75) between IE patients treated before and after the implementation of the ET. CONCLUSION: Formalization of the recommended multidisciplinary endocarditis team might not significantly improve the complication rate nor the short term outcome.

[ESC/EACTS guidelines 2021 on the management of valvular heart diseases : What are the most important innovations?] / ESC/EACTS-Leitlinien 2021 zum Management von Herzklappenerkrankungen : Was sind die wichtigsten Neuerungen?

In August 2021 the European Society for Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) updated their guidelines on the management of valvular heart disease. Since the publication of the previous version in 2017 new evidence regarding epidemiology, diagnosis and treatment of valvular heart diseases has been accumulating, which led to reassessment of several recommendations. Most importantly, the critical role of the heart team in treatment decision-making was reemphasized, the criteria for choosing the mode of aortic valve interventions were clarified, the definition of severe secondary mitral regurgitation was revised and the recommendation for transcatheter edge-to-edge mitral valve repair in patients with this condition was upgraded. Additionally, antithrombotic therapeutic regimens in patients with native valvular heart diseases and bioprostheses were reappraised, the indications for early surgery in selected asymptomatic patient groups were expanded and the potential of transcatheter tricuspid valve interventions in inoperable and high-risk patients was acknowledged, although the latter needs to be further evaluated. This review article summarizes the most important recommendations of the new guidelines.

BACKGROUND AND AIM OF THE STUDY: Review how advanced imaging techniques and a multidisciplinary heart team approach are used to evaluate complex cardiac structural pathology. METHODS: Single-center retrospective case series. RESULTS AND CONCLUSIONS: Cardiac computed tomography angiography in addition to transthoracic and transesophageal echocardiography impacts pre-procedural planning and procedural success.

Evidence-Based Determination of Cut-Off Points for Increased Cardiac-Surgery Mortality Risk With EuroSCORE II and STS: The Best-Performing Risk Scoring Models in a Single-Centre Australian Population.

OBJECTIVES: Risk scoring models (RSMs) are commonly used for estimation of postoperative-mortality risk in patients undergoing cardiac surgery, but their prediction accuracy may vary in different populations and clinical situations. The prognostic accuracies of some RSMs have not yet been fully evaluated in the Australian population. In this retrospective observational study, our aims were to assess the performance of four contemporary RSMs, to identify the best RSMs for prediction of postoperative-mortality in the single-centre cohort, and to determine a statistical threshold for classification of patients with increased or "higher" mortality risk. METHODS: The study population included patients who underwent cardiac surgery at Liverpool Hospital between January 2013 and December 2014. Demographic information was collected, and mortality risks were estimated with the ES2 (EuroSCORE II), STS (Society of Thoracic Surgeons Score), AS (AusSCORE total) and ASMR (AusSCORE multi-risk) RSMs. (Additive EuroSCORE) (AES) and LES (logistic EuroSCORE) were included for historical interest. Discrimination, the ability to stratify patients between mortality and no mortality outcomes, and calibration, the comparison of risk score estimated and observed outcome in the population, were evaluated for each RSM, to determine their predictive accuracy in the study population. Discrimination was assessed by the AUC (area under the receiver operating characteristic curve), and acceptable calibration by the p-value greater than 0.05 for the Hosmer-Lemeshow (H-L) test. The best AUCs in contempory models were compared using the DeLong test. For ES2 and STS risk scores, cut-off points, or thresholds, for patients at increased risk of mortality were derived using Youden's J-statistics, calculated from sensitivity and specificity of models in predicting mortality. RESULTS: From a total study population of 898 patients, 738 had scores for all six RSMs. The three EuroSCORE risk models and Youden's J-statistics analysis included the total population. Of the models in contemporary use, ES2 had higher discrimination (AUC=0.850) in this population than ASMR (AUC=0.767, p=0.024) and AS (AUC=0.739) and non-significantly higher discrimination than STS (AUC=0.806, p=0.19). All contemporary models had acceptable calibration but the older LES (H-L p=0.024) did not. Estimated mortality was closest to observed mortality with the ES2 model. Both AES and LES over predicted mortality. The RSM with the highest discrimination in isolated coronary artery bypass graft surgery (CAGs) (AUC=0.847), isolated valves (AUC=0.830), and females (AUC=0.784) was the ES2 model. STS discrimination was highest in CAGs plus valve procedures (AUC 0.891), and males (STS AUC=0.891). Cut-off points for risk scores to define increased risk populations were 3.0% for ES2 and 1.7% for STS. Similar proportions of patients in each RSM (ES2-26% to STS-32%) were defined as higher risk by the model threshold score depending on type of procedure. CONCLUSION: Among RSMs in contemporary use, ES2 and STS showed the best discrimination and acceptable calibration. Caution is recommended in specific subgroups. Increased mortality risk score cut-off points could be identified for these two RSMs in this single-centre cohort.

Decision making in treatment of symptomatic severe aortic stenosis: a survey study in Dutch heart centres.

AIM: To provide insight into the basic characteristics of decision making in the treatment of symptomatic severe aortic stenosis (SSAS) in Dutch heart centres with specific emphasis on the evaluation of frailty, cognition, nutritional status and physical functioning/functionality in (instrumental) activities of daily living [(I)ADL]. METHODS: A questionnaire was used that is based on the European and American guidelines for SSAS treatment. The survey was administered to physicians and non-physicians in Dutch heart centres involved in the decision-making pathway for SSAS treatment. RESULTS: All 16 Dutch heart centres participated. Before a patient case is discussed by the heart team, heart centres rarely request data from the referring hospital regarding patients' functionality (n = 5), frailty scores (n = 0) and geriatric consultation (n = 1) as a standard procedure. Most heart centres 'often to always' do their own screening for frailty (n = 10), cognition/mood (n = 9), nutritional status (n = 10) and physical functioning/functionality in (I)ADL (n = 10). During heart team meetings data are 'sometimes to regularly' available regarding frailty (n = 5), cognition/mood (n = 11), nutritional status (n = 8) and physical functioning/functionality in (I)ADL (n = 10). After assessment in the outpatient clinic patient cases are re-discussed 'sometimes to regularly' in heart team meetings (n = 10). CONCLUSIONS: Dutch heart centres make an effort to evaluate frailty, cognition, nutritional status and physical functioning/functionality in (I)ADL for decision making regarding SSAS treatment. However, these patient data are not routinely requested from the referring hospital and are not always available for heart team meetings. Incorporation of these important data in a structured manner early in the decision-making process may provide additional useful information for decision making in the heart team meeting.

CARDIOPULMONARY BYPASS IN PREGNANCY. A SINGLE-CENTER EXPERIENCE.

OBJECTIVE: The aim: Presentation of a single-center experience of cardiac surgery with cardiopulmonary bypass (CPB) in pregnant women with critical cardiac pathology. The possibility of minimally invasive technique in this group of patients were presented. PATIENTS AND METHODS: Materials and methods: The present study included 19 cases of multidisciplinary care with CPB surgery in pregnant women in single center from December 2013 to December 2020. 8 patients underwent J-form median mini-sternotomy. Maternal and neonatal outcomes depending on the type of surgery (urgent or elective) were reviewed. RESULTS: Results: There were no negative maternal consequences; there were 4 perinatal losses (21%): three after urgent and one after elective interventions. All other pregnancies (n=15) finished successfully with the birth of healthy newborns. We compared some values in two groups (urgent and elective) of patients who underwent CPB surgery during pregnancy. Despite the variability in some parameters the difference between the groups was not significant. Follow-up was from 5 to 72 months (39.7±16.9) without negative consequences. CONCLUSION: Conclusions: Multidisciplinary team management is an effective strategy for pregnant women with cardiac pathology. Elective cardiac surgery in expert centers during pregnancy is a safe and effective option. Urgent CPB cardiac surgery during pregnancy increases the risk for the fetus. J-form median mini-sternotomy is a good option during pregnancy in high-experienced centers.

Predictors of short- and long-term outcomes of patients undergoing transcatheter mitral valve edge-to-edge repair.

OBJECTIVES: Transcatheter mitral valve repair (TMVR) by edge-to-edge therapy is an established treatment for severe mitral valve regurgitation (MR). BACKGROUND: Symptomatic and prognostic benefit in functional MR has been shown recently; nevertheless, data on long-term outcomes are sparse. METHODS AND RESULTS: We analyzed survival of patients treated with isolated edge-to-edge repair from June 2010 to March 2018 (primarily combined edge-to-edge repair with other mitral valve interventions was excluded) in a retrospective monocentric study. Overall, 627 consecutive patients (47.0% females, 78.6 years in mean) were included. Leading etiology was functional MR (57.4%). Follow-up regarding survival was available in 97.0%. While 97.6% were discharged alive, 75.7% were alive after a 1-year, 54.5% after 3-year, 37.6% after 5-year and 21.7% after 7-year follow-up. Higher logistic Euroscores and comorbidities such as COPD and renal insufficiency were associated with higher in-hospital and 1-year mortality. Importantly, in-hospital survival increased over the years. CONCLUSIONS: With the present study we established high survival rates at discharge and after 1 year of patients treated with TMVR. This goes along with high implantation numbers, increased interventional experience and a better in-hospital survival over the years. Long-term mortality in turn was substantially influenced by comorbidities.

Iatrogenic aorta-coronary dissection: Case report and systematic review.

OBJECTIVES AND BACKGROUND: Iatrogenic aorto-coronary dissection (ICD) is one of the most feared complications of interventional cardiology. Although rare, it is characterized by anterograde coronary ischemia and a concomitant aortic dissection, with potentially fatal consequences. METHODS: We present an example case of IACD and an accurate case-series review of the literature including 125 published cases. RESULTS: There were no significant predisposing factors and the IACD occurred equally in elective and urgent procedures. A significant number of IACDs were associated with CTO procedures. The factors associated with a worse outcome were hemodynamic instability, the presence of anterograde ischemia, and the extent of dissection according to the Dunning classification. Bail-out stenting was the most used strategy and its failure was associated with mortality. CONCLUSION: The main features of IACD are anterograde ischemia, retrograde dissection, and hemodynamic instability, each of them should be addressed with no time delay, possibly with bailout stenting, the most employed exit-strategy. According to our proposed algorithm, a shock team approach is required to coordinate the interdisciplinary skills and enabled patients to receive the best treatment.

Percutaneous puncture of an aorto-bifemoral bypass graft and successful closure with MANTA® device in transfemoral TAVR.

Transfemoral aortic valve replacement (TAVR) has become a standard therapeutic option for patients with symptomatic severe aortic stenosis. Special anatomies can pose distinct challenges for vascular access and later closure of the access site, for example, in preoperated patients. Here, we elucidate a case of transfemoral TAVR with vascular access by direct puncture of an aorto-bifemoral bypass graft and illustrate the feasibility of vascular closure by an anchored collagen-plug vascular closure device (Teleflex MANTA® ).

"Unlucky punch": unexpected annular rupture during TAVR and successful treatment.

Although rare, annular rupture in TAVR is a feared and often unpredictable complication with relevant impact on in-hospital prognosis. Severe annular calcification is a common risk factor for annular rupture. We report on a case of annular rupture during TAVR with a balloon-expanded prosthesis in the absence of any annular calcification in the planning CT scan and illustrate the proposed pathomechanism as well as its successful immediate surgical management.

Performance of the heart team approach in daily clinical practice in high-risk patients with aortic stenosis.

OBJECTIVE: The heart team (HT) approach plays a key role in selecting the optimal treatment strategy for patients with aortic stenosis (AS). However, little is known about the HT decision process and its impact on outcomes. The aim of this study was to identify the factors associated with the HT decision and evaluate clinical outcomes according to the treatment choice. METHODS: The study included a total of 286 consecutive patients with AS referred for discussion in the weekly HT meeting in a cardiovascular institute over 2 years. Patients were stratified according to the selected therapeutic approach: medical treatment (MT), surgical (SAVR), or transcatheter (TAVR) aortic valve replacement. Baseline characteristics involved in making a therapeutic choice were identified and a decision-making tree was built using classification and regression tree methodology. RESULTS: Based on HT discussion, 53 patients were assigned to SAVR, 210 to TAVR, and 23 to MT. Older patients (≥88 years old) were mainly assigned to TAVR or MT according to the logistic EuroSCORE (
