Exploring the Perioperative Use of DOACs, off the Beaten Track.

A notable increase in direct oral anticoagulant (DOAC) use has been observed in the last decade. This trend has surpassed the prescription of vitamin K antagonists (VKAs) due to the absence of the need for regular laboratory monitoring and the more favorable characteristics in terms of efficacy and safety. However, it is very common that patients on DOACs need an interventional or surgical procedure, requiring a careful evaluation and a challenging approach. Therefore, perioperative anticoagulation management of patients on DOACs represents a growing concern for clinicians. Indeed, while several surgical interventions require temporary discontinuation of DOACs, other procedures that involve a lower risk of bleeding can be conducted, maintaining a minimal or uninterrupted DOAC strategy. Therefore, a comprehensive evaluation of patient characteristics, including age, susceptibility to stroke, previous bleeding complications, concurrent medications, renal and hepatic function, and other factors, in addition to surgical considerations, is mandatory to establish the optimal discontinuation and resumption timing of DOACs. A multidisciplinary approach is required for managing perioperative anticoagulation in order to establish how to face these circumstances. This narrative review aims to provide physicians with a practical guide for DOAC perioperative management, addressing the most controversial issues.

Italian Association of Hospital Cardiologists Position Paper 'Gender discrepancy: time to implement gender-based clinical management'.

It has been well assessed that women have been widely under-represented in cardiovascular clinical trials. Moreover, a significant discrepancy in pharmacological and interventional strategies has been reported. Therefore, poor outcomes and more significant mortality have been shown in many diseases. Pharmacokinetic and pharmacodynamic differences in drug metabolism have also been described so that effectiveness could be different according to sex. However, awareness about the gender gap remains too scarce. Consequently, gender-specific guidelines are lacking, and the need for a sex-specific approach has become more evident in the last few years. This paper aims to evaluate different therapeutic approaches to managing the most common women's diseases.

Coagulation Tests and Reversal Agents in Patients Treated with Oral Anticoagulants: The Challenging Scenarios of Life-Threatening Bleeding and Unplanned Invasive Procedures.

In clinical practice, the number of patients treated with direct oral anticoagulants (DOACs) has consistently increased over the years. Since anticoagulant therapy has been associated with an annual incidence of major bleeding (MB) events of approximately 2% to 3.5%, it is of paramount importance to understand how to manage anticoagulated patients with major or life-threatening bleeding. A considerable number of these patients' conditions necessitate hospitalization, and the administration of reversal agents may be imperative to manage and control bleeding episodes effectively. Importantly, effective strategies for reversing the anticoagulant effects of DOACs have been well recognized. Specifically, idarucizumab has obtained regulatory approval for the reversal of dabigatran, and andexanet alfa has recently been approved for reversing the effects of apixaban or rivaroxaban in patients experiencing life-threatening or uncontrolled bleeding events. Moreover, continuous endeavors are being made to develop supplementary reversal agents. In emergency scenarios where specific reversal agents might not be accessible, non-specific hemostatic agents such as prothrombin complex concentrate can be utilized to neutralize the anticoagulant effects of DOACs. However, it is paramount to emphasize that specific reversal agents, characterized by their efficacy and safety, should be the preferred choice when suitable. Moreover, it is worth noting that adherence to the guidelines for the reversal agents is poor, and there is a notable gap between international recommendations and actual clinical practices in this regard. This narrative review aims to provide physicians with a practical approach to managing specific reversal agents.

Heart Failure with Preserved Ejection Fraction: How to Deal with This Chameleon.

Heart failure with preserved ejection fraction (HFpEF) is characterized by a notable heterogeneity in both phenotypic and pathophysiological features, with a growing incidence due to the increase in median age and comorbidities such as obesity, arterial hypertension, and cardiometabolic disease. In recent decades, the development of new pharmacological and non-pharmacological options has significantly impacted outcomes, improving clinical status and reducing mortality. Moreover, a more personalized and accurate therapeutic management has been demonstrated to enhance the quality of life, diminish hospitalizations, and improve overall survival. Therefore, assessing the peculiarities of patients with HFpEF is crucial in order to obtain a better understanding of this disorder. Importantly, comorbidities have been shown to influence symptoms and prognosis, and, consequently, they should be carefully addressed. In this sense, it is mandatory to join forces with a multidisciplinary team in order to achieve high-quality care. However, HFpEF remains largely under-recognized and under-treated in clinical practice, and the diagnostic and therapeutic management of these patients remains challenging. The aim of this paper is to articulate a pragmatic approach for patients with HFpEF focusing on the etiology, diagnosis, and treatment of HFpEF.

Anderson-Fabry Disease: Red Flags for Early Diagnosis of Cardiac Involvement.

Anderson-Fabry disease (AFD) is a lysosome storage disorder resulting from an X-linked inheritance of a mutation in the galactosidase A (GLA) gene encoding for the enzyme alpha-galactosidase A (α-GAL A). This mutation results in a deficiency or absence of α-GAL A activity, with a progressive intracellular deposition of glycosphingolipids leading to organ dysfunction and failure. Cardiac damage starts early in life, often occurring sub-clinically before overt cardiac symptoms. Left ventricular hypertrophy represents a common cardiac manifestation, albeit conduction system impairment, arrhythmias, and valvular abnormalities may also characterize AFD. Even in consideration of pleiotropic manifestation, diagnosis is often challenging. Thus, knowledge of cardiac and extracardiac diagnostic "red flags" is needed to guide a timely diagnosis. Indeed, considering its systemic involvement, a multidisciplinary approach may be helpful in discerning AFD-related cardiac disease. Beyond clinical pearls, a practical approach to assist clinicians in diagnosing AFD includes optimal management of biochemical tests, genetic tests, and cardiac biopsy. We extensively reviewed the current literature on AFD cardiomyopathy, focusing on cardiac "red flags" that may represent key diagnostic tools to establish a timely diagnosis. Furthermore, clinical findings to identify patients at higher risk of sudden death are also highlighted.

[Gender discrepancy: time to implement gender-based clinical management]. / Position paper ANMCO: Differenze di genere nell'approccio farmacologico cardiovascolare.

It is well established that gender strongly influences cardiovascular risk factors, playing a crucial role in cardiovascular prevention, clinical pathways, diagnostic approach and treatment. Beyond the sex, which is a biological factor, gender entails a socio-cultural condition that impacts access and quality of care due to structural and institutional barriers. However, despite its great importance, this issue has not been adequately covered. Indeed sex and gender differences scarcely impact the clinical approach, creating a lot of disparities in care and outcomes of patients. Therefore, it becomes essential to increase the awareness of the importance of sex and gender influences on cardiovascular diseases. Moreover, new strategies for reducing disparities should be developed. Importantly, these differences should be taken into account in guideline recommendations. In this regard, it is crucial to include a greater number of women in clinical trials, since they are currently underrepresented. Furthermore, more women should be involved as member of international boards in order to develop recommendations and guidelines with more attention to this important topic.The aim of this ANMCO position paper is to shed light on gender differences concerning many cardiovascular drugs in order to encourage a more personalized therapeutic approach.

Long-term prognosis in patients undergoing redo-isolated aortic valve replacement.

Aim: To evaluate clinical outcomes after redo aortic valve replacement (AVR) with sutured valves, versus valve-in-valve transcatheter aortic valve replacement (ViV-TAVR), versus sutureless valves. Methods: We identified 113 consecutive patients undergoing redo AVR with either ViV-TAVR, redo-sutured and redo-sutureless valves between August 2010 to March 2020. Heart-team made the decision whether patient should undergo redo-sutureless versus ViV-TAVR, versus redo-sutured AVR. Results: Preoperatively, redo-sutured (n = 57), ViV-TAVR (n = 31) and redo-sutureless (n = 25) patients were compared. Postoperatively, after propensity-adjustment analysis, the redo surgical aortic valve replacement group had a higher incidence of new postoperative atrial fibrillation (POAF; p = 0.04) compared with redo-sutureless group. Follow-up outcomes analysis did not show differences among groups. Conclusion: Patients undergoing redo-sutureless AVR experienced a higher incidence of POAF compared with patients undergoing redo-sutured.

[ANMCO Position paper: Ionizing radiation exposure and radioprotection in the cath-lab]. / Position paper ANMCO: Radioesposizione e radioprotezione nei laboratori di cardiologia interventistica.

In the last decades, because of the improvements in the percutaneous treatment of coronary heart disease, valvular heart disease, congenital heart defects, and the increasing number of cardiac resynchronization therapy and cardioverter-defibrillator implantations, the interventional cardiologists' radio-exposure has importantly risen, causing concerns for ionizing radiation-associated diseases such as cancer and neurodegenerative disorders. Consequently, the radiation exposure issue importantly affects operators' safety. However, our knowledge of this field is poor and most operators are unaware to be at risk, especially because of the absence of effective preventive measures. The aim of this ANMCO position paper is to improve the awareness of operators and identify new ways of reducing operator ionizing radiation dose and minimizing the risk.

Management of Patients Treated with Direct Oral Anticoagulants in Clinical Practice and Challenging Scenarios.

It is well established that direct oral anticoagulants (DOACs) are the cornerstone of anticoagulant strategy in atrial fibrillation (AF) and venous thromboembolism (VTE) and should be preferred over vitamin K antagonists (VKAs) since they are superior or non-inferior to VKAs in reducing thromboembolic risk and are associated with a lower risk of intracranial hemorrhage (IH). In addition, many factors, such as fewer pharmacokinetic interactions and less need for monitoring, contribute to the favor of this therapeutic strategy. Although DOACs represent a more suitable option, several issues should be considered in clinical practice, including drug-drug interactions (DDIs), switching to other antithrombotic therapies, preprocedural and postprocedural periods, and the use in patients with chronic renal and liver failure and in those with cancer. Furthermore, adherence to DOACs appears to remain suboptimal. This narrative review aims to provide a practical guide for DOAC prescription and address challenging scenarios.

[ANMCO Position paper: Choosing Wisely - ANMCO proposals for 2023]. / Position paper ANMCO: Choosing Wisely ­ le proposte dell'ANMCO nel 2023.

Nowadays, a progressive and exponential increase in the use of invasive and non-invasive instrumental diagnostics and therapeutic services has been shown. Although unnecessary, instrumental examinations are often largely prescribed, replacing clinical evaluation. Their correct use, on the contrary, would address precise epidemiological and clinical contexts. Therefore identifying whether a test or procedure is appropriate or not plays a crucial role in clinical practice. Several documents from scientific societies and expert groups indicate the most appropriate cardiovascular diagnostic and therapeutic procedures. The international Choosing Wisely campaign invited the main scientific societies to identify five techniques or treatments used in their field that are often unnecessary and may potentially damage patients. The Italian Association of Hospital Cardiologists (ANMCO) joined the project identifying the five cardiological practices in our country at greater risk of inappropriateness in 2014. This list has recently been updated. Moreover, possible solutions to this problem have been proposed.

Management of oral anticoagulant therapy after intracranial hemorrhage in patients with atrial fibrillation.

Intracranial hemorrhage (ICH) is considered a potentially severe complication of oral anticoagulants (OACs) and antiplatelet therapy (APT). Patients with atrial fibrillation (AF) who survived ICH present both an increased ischemic and bleeding risk. Due to its lethality, initiating or reinitiating OACs in ICH survivors with AF is challenging. Since ICH recurrence may be life-threatening, patients who experience an ICH are often not treated with OACs, and thus remain at a higher risk of thromboembolic events. It is worthy of mention that subjects with a recent ICH and AF have been scarcely enrolled in randomized controlled trials (RCTs) on ischemic stroke risk management in AF. Nevertheless, in observational studies, stroke incidence and mortality of patients with AF who survived ICH had been shown to be significantly reduced among those treated with OACs. However, the risk of hemorrhagic events, including recurrent ICH, was not necessarily increased, especially in patients with post-traumatic ICH. The optimal timing of anticoagulation initiation or restarting after an ICH in AF patients is also largely debated. Finally, the left atrial appendage occlusion option should be evaluated in AF patients with a very high risk of recurrent ICH. Overall, an interdisciplinary unit consisting of cardiologists, neurologists, neuroradiologists, neurosurgeons, patients, and their families should be involved in management decisions. According to available evidence, this review outlines the most appropriate anticoagulation strategies after an ICH that should be adopted to treat this neglected subset of patients.

Congenital Ventricular Diverticulum.

Herein, we describe a 54-year-old patient with a congenital ventricular diverticulum (CVD), referred to our emergency department for presyncope episodes and multiple re-entrant ventricular tachycardias (VT). Significantly, echocardiographic findings were not clear, and the diagnosis was made by cardiac magnetic resonance imaging (CMRI), which showed the presence of an apical accessory cavity connected to the ventricle and contracting synchronously. CMRI allowed the differential diagnosis with other outpouching cardiac defects. The patient underwent a subcutaneous implantable cardioverter defibrillator (S-ICD) implant and was referred for heart transplantation (HT). The diagnosis, treatment, and main findings of the CVD are discussed in this case report.

The role of the pregnancy heart team in clinical practice.

Significant maternal and fetal morbidity and mortality risk has been shown to be associated with cardiovascular disease in pregnancy. Several determinants, such as the increasing number of females with corrected congenital heart disease in reproductive age, a more advanced maternal age associated with cardiovascular risk factors, and a greater prevalence of preexisting comorbidities related to cardiac disorders such as cancer and COVID-19), lead to a higher incidence of cardiac complications in pregnancy in the last few decades. However, adopting a multidisciplinary strategy may influence maternal and neonatal outcomes. This review aims at assessing the role of the Pregnancy Heart Team, which should ensure careful pre-pregnancy counseling, pregnancy monitoring, and delivery planning for both congenital and other cardiac or metabolic disorders, addressing several emerging aspects in the multidisciplinary team-based approach.

Clinical Utility of Three-Dimensional Echocardiography in the Evaluation of Mitral Valve Disease: Tips and Tricks.

Although real-time 3D echocardiography (RT3DE) has only been introduced in the last decades, its use still needs to be improved since it is a time-consuming and operator-dependent technique and acquiring a good quality data can be difficult. Moreover, the additive value of this important diagnostic tool still needs to be wholly appreciated in clinical practice. This review aims at explaining how, why, and when performing RT3DE is useful in clinical practice.

Risk predictors that impact long-term prognosis in patients undergoing aortic valve replacement with the Perceval sutureless bioprosthesis.

BACKGROUND: The aim of this study is to identify risk predictors that impact long-term prognosis in patients undergoing isolated aortic valve replacement (AVR) with Perceval sutureless bioprosthesis aortic valve implantation. METHODS: From 2013 to 2020, 101 consecutive participants who underwent isolated AVR with the Perceval sutureless bioprosthesis were included. Primary endpoint was analysis of all-cause mortality. We performed a propensity-adjusted analysis of patients undergoing redo sutureless vs redo sutured AVR to understand the impact of sutureless valves in redo operations. RESULTS: Pre-operative characteristics included a mean age of 71.2-years, mean EuroScore II of 3.51 (±4.48), mean body mass index of 30.2 (±6.8). Mean follow-up was 1.5 years. Intraoperatively, mean cardiopulmonary bypass time and aortic cross-clamp time were 65 ± 29.6 and 47.3 ± 21.3 min, respectively. Valve redeployment was necessary in 9.9 % of cases and there was one intraoperative death. There were two hospital deaths (including the operative death) while only one was cardiac related. Postoperatively, mean ejection fraction was 55.5 % (±4.1 %), mean effective orifice was 1.5 (±0.3) cm2, and mean transvalvular gradient was 14.7 (±4) mmHg. At 7-years follow-up, 87.9 % of patients were alive. Risk predictors for all-cause death were female sex and left ventricular diastolic dysfunction (LVDD) grade ≥ 2. After matching, aortic cross-clamp time, inotrope use, blood product transfusions, respiratory failure, and post-operative arrhythmias were higher in the redo sutured group compared to the sutureless redo group. CONCLUSIONS: Sutureless aortic valve implantations have good clinical outcomes. Risk predictors for all-cause death included female sex and LVDD grade ≥ 2.

Patent Foramen Ovale and Cryptogenic Stroke: Integrated Management.

Patent foramen ovale (PFO) is a common cardiac abnormality with a prevalence of 25% in the general population. PFO has been associated with the paradoxical embolism causing cryptogenic stroke and systemic embolization. Results from clinical trials, meta-analyses, and position papers support percutaneous PFO device closure (PPFOC), especially if interatrial septal aneurysms coexist and in the presence of large shunts in young patients. Remarkably, accurately evaluating patients to refer to the closure strategy is extremely important. However, the selection of patients for PFO closure is still not so clear. The aim of this review is to update and clarify which patients should be considered for closure treatment.

Machine Learning to Identify Patients at Risk of Developing New-Onset Atrial Fibrillation after Coronary Artery Bypass.

BACKGROUND: This study aims to get an effective machine learning (ML) prediction model of new-onset postoperative atrial fibrillation (POAF) following coronary artery bypass grafting (CABG) and to highlight the most relevant clinical factors. METHODS: Four ML algorithms were employed to analyze 394 patients undergoing CABG, and their performances were compared: Multivariate Adaptive Regression Spline, Neural Network, Random Forest, and Support Vector Machine. Each algorithm was applied to the training data set to choose the most important features and to build a predictive model. The better performance for each model was obtained by a hyperparameters search, and the Receiver Operating Characteristic Area Under the Curve metric was selected to choose the best model. The best instances of each model were fed with the test data set, and some metrics were generated to assess the performance of the models on the unseen data set. A traditional logistic regression was also performed to be compared with the machine learning models. RESULTS: Random Forest model showed the best performance, and the top five predictive features included age, preoperative creatinine values, time of aortic cross-clamping, body surface area, and Logistic Euro-Score. CONCLUSIONS: The use of ML for clinical predictions requires an accurate evaluation of the models and their hyperparameters. Random Forest outperformed all other models in the clinical prediction of POAF following CABG.

Ministernotomy compared with right anterior minithoracotomy for aortic valve surgery.

OBJECTIVES: Ministernotomy and right anterior minithoracotomy are the 2 main techniques applied for minimally invasive aortic valve replacement. The goal of this study is to compare early and long-term outcomes of both techniques. METHODS: The data of 2419 patients undergoing isolated minimally invasive aortic valve replacement between 1999 and 2019 were prospectively collected. Retrospectively, patients were divided into the ministernotomy group (n = 1352) and the minithoracotomy group (n = 1067). RESULTS: After propensity score matching, 986 patients remained in each group. Operation time and rate of conversion to full sternotomy were significantly higher in the minithoracotomy group than in the ministernotomy group (184.6 ± 45.2 vs 241.3 ± 68.6, relative risk, 2.54, P = .005 and .09 vs .23, relative risk, 1.45, P = .013, respectively). The 30-day mortality, excluding cardiac death, was lower in the ministernotomy group than in the minithoracotomy group (0.012 vs 0.028, relative risk, 1.41, P = .011, respectively); the intensive care unit length of stay (12.4 vs 16.5, relative risk, 1.62, P = .037, respectively) and hospital length of stay (5.4 vs 8.7, relative risk, 1.74 P = .028, respectively) were significantly longer in the minithoracotomy group. The minithoracotomy surgical approach was the strongest independent predictor of early mortality (odds ratio, 4.24 [1.67-7.35], P = .002). The actuarial survival by Kaplan-Meier analysis at 1, 3, 5, 10, and 20 years was significantly better in the ministernotomy group than in the minithoracotomy group (P = .0001). Actuarial freedom from reoperation at 5 years was 97.3% ± 4.4% in the ministernotomy group versus 95.8% ± 5.2% in the minithoracotomy group (P = .087). CONCLUSIONS: Minimally invasive aortic valve replacement using ministernotomy is associated with reduced operative time, intensive care unit stay, hospital length of stay, and postoperative morbidities and incisional pain, and improves early and long-term mortality.

Esophageal Protection and Temperature Monitoring Using the Circa S-Cath™ Temperature Probe during Epicardial Radiofrequency Ablation of the Pulmonary Veins and Posterior Left Atrium.

Although epicardial bipolar radiofrequency ablation should diminish the risk of esophageal thermal injury in comparison to an endocardial ablation, cases of lethal atrio-esophageal fistula have been reported. To better understand this risk and to reduce the possibility of a thermal injury, we monitored the esophageal temperature with the Circa S-Cath™ temperature probe during and immediately after the ablation while implementing three procedural safety measures. Twenty patients (15 males; 63 ± 10 years) were prospectively enrolled (November 2019-February 2021). All patients underwent an epicardial ablation procedure, including an antral left and right pulmonary vein isolation with bidirectional bipolar clamping, and a roof and inferior line using unidirectional bipolar radiofrequency. Three procedural preventive mitigations were implemented: (1) transesophageal echocardiographic visualization of the atrio-esophageal interface, with probe retraction before the energy delivery; (2) lifting the ablated tissue away from the esophagus during an energy application; and (3) a 30 s cool-off and irrigation period after the energy delivery. The esophageal temperature was recorded using an insulated multisensory intraluminal esophageal temperature probe (Circa S-Cath™). Of the 20 patients enrolled, 7 patients had paroxysmal atrial fibrillation (AF), 8 persistent AF and 5 longstanding persistent AF. The average maximum luminal esophageal temperature observed was 36.2 ± 0.7 °C (34.8-38.2 °C). In our clinical experience, no abrupt increase in the luminal esophageal temperature above the baseline was observed. Since no measurements exceeded the threshold of 39 °C, no prompt interruption of energy delivery was required. Intraluminal esophageal temperature monitoring is feasible and can be helpful in confirming correct catheter position and safe energy application in bipolar epicardial left atrial ablation. Intra-procedural preventive mitigations should be implemented to reduce the risk of esophageal temperature rises.
