Cardiac Magnetic Resonance for Structural Aortic Valve Stenosis Procedures.

The number of structural aortic valve procedures has increased significantly in recent years. Pre-procedural planning and follow-up with noninvasive testing are essential. Although cardiac magnetic resonance (CMR) is the gold standard for assessing left ventricular mass, volume, and function, it is not performed routinely in patients undergoing structural interventions. CMR can provide useful information for pre- and post-procedural assessment, including quantification of cardiac function, myocardial assessment, grading of the severity of valvular heart disease, and evaluation of extracardiac anatomy while avoiding the limitations of other non-invasive modalities. Here, we review the use cases, future perspectives, and limitations of CMR for patients undergoing structural aortic valve procedures.

Aortic Pseudoaneurysm-Related Acute Ortner's Syndrome Presenting as Sudden Hoarseness: A Case Series.

BACKGROUND Ortner syndrome, or cardiovocal syndrome, is a left recurrent laryngeal nerve palsy secondary to cardiovascular causes. Aortic pseudoaneurysm is a rare life-threatening condition resulting from weakening of the aortic wall. Clinical presentation of aortic pseudoaneurysm is highly variable. Hoarseness is often caused by benign conditions; however, it can be the first symptom of an underlying serious condition requiring immediate diagnosis and management. CASE REPORT We report a series of 2 patients with sudden hoarseness as the first symptom of an aortic arch pseudoaneurysm. Two men, with ages of 76 and 60 years, had sudden hoarseness a few weeks before. Laryngoscopy showed a left vocal cord palsy in both cases. A computed tomography (CT) scan showed a thoracic aortic pseudoaneurysm located at the aortic arch compressing the left recurrent laryngeal nerve. Both patients were treated with endovascular aortic repair. The first patient underwent a carotid-subclavian artery bypass, and the left subclavian artery was closed with a vascular plug device. He was discharged a week later, with persistent hoarseness. In the second case, subclavian artery occlusion and pseudoaneurysm embolization with coils were performed. Control CT scan confirmed the procedure's success. However, after an initial favorable evolution, the patient had severe non-vascular complications and finally died. CONCLUSIONS Considering these 2 cases and those reported in the literature, aortic origin should be considered in the differential diagnosis of hoarseness, particularly when it appears suddenly. Thoracic endovascular aortic repair is a feasible option for those patients with penetrating aortic ulcer or pseudoaneurysm located in the aortic arch.

Diabetes mellitus is associated to high-risk late gadolinium enhancement and worse outcomes in patients with nonischemic dilated cardiomyopathy.

BACKGROUND: Diabetes mellitus (DM) is associated with a worse prognosis in patients with heart failure. Our aim was to analyze the clinical and imaging features of patients with DM and their association with outcomes in comparison to nondiabetic patients in a cohort of patients with nonischemic dilated cardiomyopathy (DCM). METHODS: This is a prospective cohort study of patients with DCM evaluated in a tertiary care center from 2018 to 2021. Transthoracic echocardiography and cardiac magnetic resonance findings were assessed. A high-risk late gadolinium enhancement (LGE) pattern was defined as epicardial, transmural, or septal plus free-wall. The primary outcome was a composite of heart failure hospitalizations and all-cause mortality. Multivariable analyses were performed to evaluate the impact of DM on outcomes. RESULTS: We studied 192 patients, of which 51 (26.6%) had DM. The median left ventricular ejection fraction was 30%, and 106 (55.2%) had LGE. No significant differences were found in systolic function parameters between patients with and without DM. E/e values were higher (15 vs. 11.9, p = 0.025), and both LGE (68.6% vs. 50.4%; p = 0.025) and a high-risk LGE pattern (31.4% vs. 18.5%; p = 0.047) were more frequently found in patients with DM. The primary outcome occurred more frequently in diabetic patients (41.2% vs. 23.6%, p = 0.017). DM was an independent predictor of outcomes (OR 2.01; p = 0.049) and of LGE presence (OR 2.15; p = 0.048) in the multivariable analysis. Patients with both DM and LGE had the highest risk of events (HR 3.1; p = 0.003). CONCLUSION: DM is related to a higher presence of LGE in DCM patients and is an independent predictor of outcomes. Patients with DM and LGE had a threefold risk of events. A multimodality imaging approach allows better risk stratification of these patients and may influence therapeutic options.

Forecasting the Risk of Heart Failure Hospitalization After Acute Coronary Syndromes: the CORALYS HF Score.

The present study aimed to identify patients at a higher risk of hospitalization for heart failure (HF) in a population of patients with acute coronary syndrome (ACS) treated with percutaneous coronary revascularization without a history of HF or reduced left ventricular (LV) ejection fraction before the index admission. We performed a Cox regression multivariable analysis with competitive risk and machine learning models on the incideNce and predictOrs of heaRt fAiLure After Acute coronarY Syndrome (CORALYS) registry (NCT04895176), an international and multicenter study including consecutive patients admitted for ACS in 16 European Centers from 2015 to 2020. Of 14,699 patients, 593 (4.0%) were admitted for the development of HF up to 1 year after the index ACS presentation. A total of 2 different data sets were randomly created, 1 for the derivative cohort including 11,626 patients (80%) and 1 for the validation cohort including 3,073 patients (20%). On the Cox regression multivariable analysis, several variables were associated with the risk of HF hospitalization, with reduced renal function, complete revascularization, and LV ejection fraction as the most relevant ones. The area under the curve at 1 year was 0.75 (0.72 to 0.78) in the derivative cohort, whereas on validation, it was 0.72 (0.67 to 0.77). The machine learning analysis showed a slightly inferior performance. In conclusion, in a large cohort of patients with ACS without a history of HF or LV dysfunction before the index event, the CORALYS HF score identified patients at a higher risk of hospitalization for HF using variables easily accessible at discharge. Further approaches to tackle HF development in this high-risk subset of patients are needed.

Impact of Complete Revascularization on Development of Heart Failure in Patients With Acute Coronary Syndrome and Multivessel Disease: A Subanalysis of the CORALYS Registry.

Background The impact of complete revascularization (CR) on the development of heart failure (HF) in patients with acute coronary syndrome and multivessel coronary artery disease undergoing percutaneous coronary intervention remains to be elucidated. Methods and Results Consecutive patients with acute coronary syndrome with multivessel coronary artery disease from the CORALYS (Incidence and Predictors of Heart Failure After Acute Coronary Syndrome) registry were included. Incidence of first hospitalization for HF or cardiovascular death was the primary end point. Patients were stratified according to completeness of coronary revascularization. Of 14 699 patients in the CORALYS registry, 5054 presented with multivessel disease. One thousand four hundred seventy-three (29.2%) underwent CR, while 3581 (70.8%) did not. Over 5 years follow-up, CR was associated with a reduced incidence of the primary end point (adjusted hazard ratio [HR], 0.66 [95% CI, 0.51-0.85]), first HF hospitalization (adjusted HR, 0.67 [95% CI, 0.49-0.90]) along with all-cause death and cardiovascular death alone (adjusted HR, 0.74 [95% CI, 0.56-0.97] and HR, 0.56 [95% CI, 0.38-0.84], respectively). The results were consistent in the propensity-score matching population and in inverse probability treatment weighting analysis. The benefit of CR was consistent across acute coronary syndrome presentations (HR, 0.59 [95% CI, 0.39-0.89] for ST-segment elevation myocardial infarction and HR, 0.71 [95% CI, 0.50-0.99] for non-ST-elevation acute coronary syndrome) and in patients with left ventricular ejection fraction >40% (HR, 0.52 [95% CI, 0.37-0.72]), while no benefit was observed in patients with left ventricular ejection fraction ≤40% (HR, 0.77 [95% CI, 0.37-1.10], P for interaction 0.04). Conclusions CR after acute coronary syndrome reduced the risk of first hospitalization for HF and cardiovascular death, as well as first HF hospitalization, and cardiovascular and overall death both in patients with ST-segment elevation myocardial infarction and non-ST-elevation acute coronary syndrome.

IncidenCe and predictOrs of heaRt fAiLure after acute coronarY Syndrome: The CORALYS registry.

BACKGROUND: Previous studies investigating predictors of Heart Failure (HF) after acute coronary syndrome (ACS) were mostly conducted during fibrinolytic era or restricted to baseline characteristics and diagnoses prior to admission. We assessed the incidence and predictors of HF hospitalizations among patients treated with percutaneous coronary intervention (PCI) for ACS. METHODS AND RESULTS: CORALYS is a multicenter, retrospective, observational registry including consecutive patients treated with PCI for ACS. Patients with known history of HF or reduced left ventricular ejection fraction (LVEF) were excluded. Incidence of HF hospitalizations was the primary endpoint. The composite of HF hospitalization or cardiovascular death, and cardiovascular and all-cause death were the secondary endpoints. Predictors of HF hospitalizations and the impact of HF hospitalization on cardiovascular and all-cause death were assessed by means of multivariable Cox proportional hazards model.14699 patients were included. After 2.9 ± 1.8 years, the incidence of HF hospitalizations was 12.7%. Multivariable analysis identified age, diabetes, chronic kidney disease, previous myocardial infarction, atrial fibrillation, pulmonary disease, GRACE risk-score ≥ 141, peripheral artery disease, cardiogenic shock at admission and LVEF ≤40% as independently associated with HF hospitalizations. Complete revascularization was associated with a lower risk of HF (HR 0.46,95%CI 0.39-0.55). HF hospitalization was associated with higher risk of CV and all-cause death (HR 1.89,95%CI 1.5-2.39 and HR 1.85,95%CI 1.6-2.14, respectively). CONCLUSIONS: Incidence of HF hospitalizations among patients treated with PCI for ACS is not negligible and is associated with detrimental impact on patients' prognosis. Several variables may help to assess the risk of HF after ACS.

[Manejo de la cesación tabáquica entre residentes de cardiología de Iberoamérica]. / Smoking cessation management among Iberoamerica's cardiology residents

Introduction and objectives: Although cardiologists frequently assist patients who suffer damage from smoking, the degree of training they receive to manage this problem during their residency is unknown. Because of this, we'd proposed to ­evaluate the preferences and practices of cardiology residents for smoking cessation of the attending patients. Materials and methods: Closed, prefixed, voluntary and anonymous survey among doctors who carried out the specialty of cardiology in 5 countries of Latin America and Spain. Results: 716 residents were surveyed; 62.4% from Argentina, 19% from Mexico, 6.8% from Spain, 6.7% from Chile, 3.2% from Uruguay, and 1.9% from Paraguay. When asked about the importance they assigned to this problem (using a scale of 1-10), 85.8% assigned this question a score of 8 or higher. While 80.5% of the participants expressed giving short anti-tobacco advice routinely, only 27.7% used pharmacological therapy for this purpose. Among those who did not use pharmacological therapy, 58.3% said that the reason was not being familiar with the treatments; 62.9% of the surveyed said they had not received any type of training in this problem. Those residents who received some type of training reported feeling more prepared for this (p < 0.0001). Conclusion: We found that cardiology residents have a low knowledge of pharmacological treatment and relatively low confidence to provide assistance in smoking cessation. This topic should be included in the training of future cardiologists in order to achieve a more comprehensive cardiovascular prevention.

Introducción y objetivos: Si bien los cardiólogos asisten cotidianamente a pacientes que sufren daño por el tabaquismo, no se conoce el grado de formación que reciben sobre esta problemática durante su residencia. Debido a ello nos propusimos evaluar las preferencias y prácticas de los residentes de cardiología para la cesación tabáquica de los pacientes que asisten. Materiales y métodos: Encuesta cerrada, prefijada, voluntaria y anónima entre médicos que realizaban la especialidad de cardiología en cinco países de Latinoamérica y España. Resultados: Se encuestaron 716 residentes: un 62.4% de Argentina, un 19% de México, un 6.8% de España, un 6.7% de Chile, un 3.2% de Uruguay y un 1.9% de Paraguay. Con respecto a la importancia que asignaban a esta problemática (empleando una escala de 1-10), el 85.8% le asignó a esta pregunta una puntuación de 8 o mayor. Mientras el 80.5% de los participantes expresó dar consejo breve antitabáquico sistemáticamente, solamente un 27.7% empleaban terapia farmacológica con este fin. Entre quienes no empleaban terapia farmacológica, el 58.3% manifestó que el motivo era no encontrarse familiarizados con los tratamientos. El 62.9% de los encuestados dijo no haber recibido ningún tipo de formación en esta problemática. Aquellos residentes que recibieron algún tipo de formación manifestaron sentirse más preparados (p < 0.0001). Conclusión: Encontramos un bajo conocimiento sobre el tratamiento farmacológico y relativamente poca seguridad por parte de los residentes de cardiología para brindar asistencia en cesación tabáquica. Consideramos esencial incluir este tópico en la formación de los futuros cardiólogos a fin de lograr una prevención cardiovascular más integral.

The SADDEN DEATH Study: Results from a Pilot Study in Non-ICU COVID-19 Spanish Patients.

Introduction: The worldwide pandemic, coronavirus disease 2019 (COVID-19) is a novel infection with serious clinical manifestations, including death. Our aim is to describe the first non-ICU Spanish deceased series with COVID-19, comparing specifically between unexpected and expected deaths. Methods: In this single-centre study, all deceased inpatients with laboratory-confirmed COVID-19 who had died from March 4 to April 16, 2020 were consecutively included. Demographic, clinical, treatment, and laboratory data, were analyzed and compared between groups. Factors associated with unexpected death were identified by multivariable logistic regression methods. Results: In total, 324 deceased patients were included. Median age was 82 years (IQR 76-87); 55.9% males. The most common cardiovascular risk factors were hypertension (78.4%), hyperlipidemia (57.7%), and diabetes (34.3%). Other common comorbidities were chronic kidney disease (40.1%), chronic pulmonary disease (30.3%), active cancer (13%), and immunosuppression (13%). The Confusion, BUN, Respiratory Rate, Systolic BP and age ≥65 (CURB-65) score at admission was >2 in 40.7% of patients. During hospitalization, 77.8% of patients received antivirals, 43.3% systemic corticosteroids, and 22.2% full anticoagulation. The rate of bacterial co-infection was 5.5%, and 105 (32.4%) patients had an increased level of troponin I. The median time from initiation of therapy to death was 5 days (IQR 3.0-8.0). In 45 patients (13.9%), the death was exclusively attributed to COVID-19, and in 254 patients (78.4%), both COVID-19 and the clinical status before admission contributed to death. Progressive respiratory failure was the most frequent cause of death (92.0%). Twenty-five patients (7.7%) had an unexpected death. Factors independently associated with unexpected death were male sex, chronic kidney disease, insulin-treated diabetes, and functional independence. Conclusions: This case series provides in-depth characterization of hospitalized non-ICU COVID-19 patients who died in Madrid. Male sex, insulin-treated diabetes, chronic kidney disease, and independency for activities of daily living are predictors of unexpected death.

Cardiogenic Shock Clinical Presentation, Management, and In-Hospital Outcomes in Patients Admitted to the Acute Cardiac Care Unit of a Tertiary Hospital: Does Gender Play a Role?

Cardiogenic shock (CS), as the most severe form of heart failure, is associated with very high mortality rates despite therapeutic advances in the last decades. Gender differences in outcomes have been widely reported regarding several cardiovascular diseases. The aim of our study was to evaluate potential gender disparities in clinical presentation, management, and in-hospital outcomes of all (n = 138) patients admitted to the Acute Cardiac Care Unit of a tertiary hospital from 2013 to 2019. Information on demographic characteristics, past medical history, haemodynamic and clinical status at admission, therapeutic management, and in-hospital outcomes was retrospectively collected. Women represented 31.88% of the cohort, were significantly older than the men and had a lower proportion of smokers, chronic obstructive pulmonary disease, and previous acute myocardial infarction (AMI). Most CSs in both groups were AMI-related. Left ventricular ejection fraction at admission was higher in women, who were less likely to receive vasopressors. No differences were observed regarding mechanical circulatory support use and in-patient outcomes, with age being the only factor associated with in-hospital mortality on multivariate analysis.

Acute Coronary Syndrome Secondary to Aortocaval Fistula.

This paper reports the case of an 88-year-old male with a history of chronic abdominal aortic aneurysm admitted to the emergency department with resting chest pain consistent with angina. Beta-blockade therapy triggered a cardiogenic shock, which motivated an urgent computed tomography scan and echocardiogram that confirmed high-output-related heart failure secondary to aortocaval fistula. (Level of Difficulty: Beginner.).
