Acceso transcava como solución al implante de TAVI en pacientes con acceso vascular complejo

TAVI implantation has become the best treatment option in high-risk patients with severe aortic stenosis. Sometimes the limiting factor is the access route to get the prosthesis into place. With this brief clinical case we show how the transcaval implant is an option that can solve these complex cases.El implante de TAVI se ha convertido en la primera opción de tratamiento en pacientes con estenosis aórtica severa de alto riesgo. Muchas veces el factor limitante es la ruta de acceso para llevar la prótesis a su lugar. Con este caso clínico breve mostramos cómo el implante transcava es una opción que puede resolver estos casos complejos.&nbsp

Average daily ischemic versus bleeding risk in patients with ACS undergoing PCI: Insights from the BleeMACS and RENAMI registries

Background: The risk of recurrent ischemia and bleeding after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) may vary during the first year of follow-up according to clinical presentation, and medical and interventional strategies. Methods: BleeMACS and RENAMI are 2 multicenter registries enrolling patients with ACS treated with PCI and clopidogrel, prasugrel, or ticagrelor. The average daily ischemic and bleeding risks (ADIR and ADBR) in the first year after PCI were the primary end points. The difference between ADBR and ADIR was calculated to estimate the potential excess of bleeding/ischemic events in a given period or specific subgroup. Results: A total of 19,826 patients were included. Overall, in the first year after PCI, the ADBR was 0.008085%, whereas ADIR was 0.008017% (P =.886). In the first 2 weeks ADIR was higher than ADBR (P =.013), especially in patients with ST-segment elevation myocardial infarction or incomplete revascularization. ADIR continued to be, albeit non-significantly, greater than ADBR up to the third month, whereas ADBR became higher, although not significantly, afterward. Patients with incomplete revascularization had an excess in ischemic risk (P =.003), whereas non–ST-segment elevation ACS patients and those on ticagrelor had an excess of bleeding (P =.012 and P =.022, respectively). Conclusions: In unselected ACS patients, ADIR and ADBR occurred at similar rates within 1 year after PCI. ADIR was greater than ADBR in the first 2 weeks, especially in ST-segment elevation myocardial infarction patients and those with incomplete revascularization. In the first year, ADIR was higher than ADBR in patients with incomplete revascularization, whereas ADBR was higher in non–ST-segment elevation ACS patients and in those discharged on ticagrelor

Data_Sheet_1_Patients’ knowledge about their involvement in clinical trials. A non-randomized controlled trial.pdf

BackgroundNowadays, good clinical practice should be established in human research. Patient’s rights and autonomy must be respected above the interest of the researcher, making mandatory to raise patient’s awareness on the implications of participating in a clinical study. Contrary to popular belief, this is not always the case. This means that, after signing the informed consent form, some patients have difficulties understanding their responsibilities as participants.Materials and methodsThis study is a prospective, multicenter, non-randomized controlled trial comparative survey conducted on patients enrolled in a clinical trial to evaluate and improve their understanding after an educational intervention was applied to the research staff.ResultsFemales were underrepresented in the clinical trials performed in this study, 21.5%. Most of the participants had a low educational level (74.4%). Around 5 and 10% of the research participants were not aware they were part of a clinical study, and more 24% just trusted in the medical decision to be enrolled. After the interventional education, the following items: “given time and resolution of the patient doubts” (p-value = 0.003), “enough written information” (p-value = 0.006), “explanation of the risks of participating in the study,” (p-value = 0.047) and understanding of the information provided to them showed an improvement regarding the study in which they were participating.ConclusionThe research participants understanding of their involvement in clinical trials is limited. An educational intervention on the research team can improve the process of empowerment and transit of information.</p

Imaging in Transcatheter Mitral Valve Replacement: State-of-Art Review

Mitral regurgitation is the second-most frequent valvular heart disease in Europe and it is associated with high morbidity and mortality. Recognition of MR should encourage the assessment of its etiology, severity, and mechanism in order to determine the best therapeutic approach. Mitral valve surgery constitutes the first-line therapy; however, transcatheter procedures have emerged as an alternative option to treat inoperable and high-risk surgical patients. In patients with suitable anatomy, the transcatheter edge-to-edge mitral leaflet repair is the most frequently applied procedure. In non-reparable patients, transcatheter mitral valve replacement (TMVR) has appeared as a promising intervention. Thus, currently TMVR represents a new treatment option for inoperable or high-risk patients with degenerated or failed bioprosthetic valves (valve-in-valve); failed repairs, (valve-in-ring); inoperable or high-risk patients with native mitral valve anatomy, or those with severe annular calcifications, or valve-in-mitral annular calcification. The patient selection requires multimodality imaging pre-procedural planning to select the best approach and device, study the anatomical landing zone and assess the risk of left ventricular outflow tract obstruction. In the present review, we aimed to highlight the main considerations for TMVR planning from an imaging perspective; before, during, and after TMVR

Coronary Artery Disease in Very Young Patients: Analysis of Risk Factors and Long-Term Follow-Up

Coronary artery disease (CAD) is a common chronic condition in the elderly. However, the earlier CAD begins, the stronger its impact on lifestyle and costs of health and social care. The present study analyzes clinical and angiographic features and the outcome of very young patients undergoing coronary angiography due to suspected CAD, including a nested case-control study of &le;40-year-old patients referred for coronary angiography. Patients were divided into two groups: cases with significant angiographic stenosis, and controls with non-significant stenosis. Of the 19,321 coronary angiographies performed in our center in a period of 10 years, 504 (2.6%) were in patients &le;40 years. The most common cardiovascular risk factors for significant CAD were smoking (OR 2.96; 95% CI 1.65&ndash;5.37), dyslipidemia (OR 2.18; 95% CI 1.27&ndash;3.82), and family history of CAD (OR 1.95; 95% CI 1.05&ndash;3.75). The incidence of major adverse cardiovascular events (MACE) at follow-up was significantly higher in the cases compared to controls (HR 2.71; 95% CI 1.44&ndash;5.11). Three conventional coronary risk factors were directly related to the early signs of CAD. MACE in the long-term follow-up is associated to dyslipidaemia and hypertriglyceridemia. Focusing efforts for the adequate control of CAD in young patients is a priority given the high socio-medical cost that this disease entails to society

Using Machine Learning Techniques to Predict MACE in Very Young Acute Coronary Syndrome Patients

Coronary artery disease is a chronic disease with an increased expression in the elderly. However, different studies have shown an increased incidence in young subjects over the last decades. The prediction of major adverse cardiac events (MACE) in very young patients has a significant impact on medical decision-making following coronary angiography and the selection of treatment. Different approaches have been developed to identify patients at a higher risk of adverse outcomes after their coronary anatomy is known. This is a prognostic study of combined data from patients &le;40 years old undergoing coronary angiography (n = 492). We evaluated whether different machine learning (ML) approaches could predict MACE more effectively than traditional statistical methods using logistic regression (LR). Our most effective model for long-term follow-up (60 &plusmn; 27 months) was random forest (RF), obtaining an area under the curve (AUC) = 0.79 (95%CI 0.69&ndash;0.88), in contrast with LR, obtaining AUC = 0.66 (95%CI 0.53&ndash;0.78, p = 0.021). At 1-year follow-up, the RF test found AUC 0.80 (95%CI 0.71&ndash;0.89) vs. LR 0.50 (95%CI 0.33&ndash;0.66, p &lt; 0.001). The results of our study support the hypothesis that ML methods can improve both the identification of MACE risk patients and the prediction vs. traditional statistical techniques even in a small sample size. The application of ML techniques to focus the efforts on the detection of MACE in very young patients after coronary angiography could help tailor upfront follow-up strategies in such young patients according to their risk of MACE and to be used for proper assignment of health resources

Centres of excellence in heart failure: results of an accreditation programme in Spain (2017–2021)

Abstract Aims To describe logistics and outcomes of the accreditation program of centres of excellence in heart failure (HF) developed in Spain by the Spanish Society of Cardiology (SEC) between 2016 and 2021. Methods and results A scientific committee created by the SEC defined three types of HF units (community, specialized, and advanced), depending on the characteristics of the hospital and their portfolio of services and equipment, as well as the quality standards required for the accreditation of excellence. The units were required to submit to the SEC a document certifying compliance with the requirements and quality standards. Once verified these, the unit received accreditation of excellence from the SEC. Between 2017 and October 2021, 78 HF units spread throughout Spain applied for accreditation. This represents 50.6% of all Spanish national health system centres with cardiology departments. Accreditation was definitive in 56.4% of the applicant centres and provisional in the remaining 43.6%. Of the 78 units, 19 were community units, 44 specialized, and 15 advanced. Of the 34 units that received provisional accreditation for failure to meet any of the required quality standards, all resolved these deficits within 6 months of the initial evaluation, subsequently receiving definitive accreditation. Conclusions Our experience indicates that implementation of an accreditation programme for excellence and quality of care of HF units at the national level by a scientific society is feasible and sustainable over time, leading the majority of HF units in the country to apply for accreditation and to meet the required quality standards
