The residents of the regions with a prevalence of >5 cases/1,000 inhabitants were the most likely to be displaced from their departments. CONCLUSIONS: According to the opinion of the participants, the impact of the COVID-19 pandemic on their academic training was more negative in third year FITs and those rotating in cardiac imaging.

Fisiopatología de la enfermedad cardiovascular en pacientes con COVID-19. Isquemia, trombosis y disfunción cardiaca / Physiopathology of cardiovascular disease in patients with COVID-19. Ischemia, thrombosis and heart failure

Las complicaciones cardiovasculares tienen una alta prevalencia en los pacientes con COVID-19 y son motivo frecuente de hospitalización, mortalidad y secuelas. En está revisión se describen los principales mecanismos fisiopatológicos implicados en la aparición de estas complicaciones. Tras la viremia inicial, se produce una infiltración y reproducción en los pulmónes, con activación del sistema inmunitario, liberación de citocinas y generación de un estado proinflamatorio con sepsis y fallo multiorgánico. El daño miocárdico puede deberse a una afección viral directa con respuesta inflamatoria local, o indirectamente a una inflamación sistémica inapropiada con marcada liberación de citocinas. Además, se genera un estado protrombótico que, junto con la afección viral vascular, pueden desencadenar eventos trombóticos e isquémicos secundarios a daño microvascular o inestabilización de placas de ateroma previas. Son necesarios nuevos estudios para esclarecer la fisiopatología tras estos eventos cardiovasculares y contribuir al desarrollo de nuevos tratamientos efectivos

Cardiovascular complications are highly prevalent in patients with COVID-19 and frequently lead to hospitalization, death and long-term morbidity. This article describes the principle pathophysiological mechanisms involved in the development of these complications. After the initial viremia, viralinvasión and replication occurs in the lungs, accompanied by immune system activation, cytokine release and the induction of a proinflammatory state, with sepsis and multiorgan failure. Myocardial injury could be due to the direct effect of viralinvasión and a local inflammatory response or to the indirect effect of inappropriate systemic inflammation involving a cytokine storm. Furthermore, the development of a prothrombotic state, together with vascular disease due to the virus, could trigger ischemic and thrombotic events secondary to microvascular damage or to the destabilization of pre-existing atheromatous plaque. New research is needed to reveal the pathophysiological mechanisms underlying these cardiovascular events and to support the development of effective new treatments

Long term follow up of percutaneous treatment for degenerated Mitroflow prosthesis with self-expanding transcatheter aortic valve implantation.

BACKGROUND: The durability of aortic valve bioprosthesis and the structural valve deterioration (SVD) are could be treated with valve-in-valve (VIV) transcatheter aortic valve implantation (TAVI). This technique has been proven to be a feasible procedure with good results in selected patients. The aim of this work was to assess the long-term results of this TAVI with an autoexpandable valve in patients with failed Mitroflow (MF) bioprosthetic aortic valves. METHODS: Single center, observational and prospective study that included 65 consecutive patients with symptomatic failed MF bioprosthetic aortic valve, treated with VIV-TAVI. The primary endpoints were clinical long-term events including all-cause mortality, cardiovascular mortality, re-hospitalization due to heart failure, stroke/transient ischemic attack (TIA) and endocarditis. Secondary endpoints were the absence of SVD or patient-prosthesis mismatch (PPM) and valve hemodynamics analysis at follow-up. RESULTS: Between March 2012 to July 2019, 65 symptomatic patients (age 80.4±5.9 years) with degenerated MF valves (numbers 19: 27.7%; 21: 38.5%; 23: 21.5%; 25: 12.3%) underwent CoreValve (n=11) or Evolut R (n=54) implantation (23, 26 and 29 mm sizes). The STS predicted risk of mortality was 6.39%±5.62%. The primary combined endpoint occurred in 32.3% of the cases. A total of 13 patients (20%) died during follow-up, but 4 (7.3%) from cardiovascular causes. Two patients were reported of having a stroke/TIA and 5 readmissions for cardiovascular causes were reported (2 of them within the first 30 days). Twenty-five patients (38.5%) presented PPM during follow-up, being PPM severe in 15 (23.1%). CONCLUSIONS: Self-expanding TAVI for degenerated MF bioprosthesis has favourable long-term outcomes. It is a good option in order to avoid the risks of redo surgery in selected patients.

Outcomes with percutaneous mitral repair vs. optimal medical treatment for functional mitral regurgitation: systematic review.

Functional mitral regurgitation (MR) could be defined as a ventricular disease where mitral valve is structurally normal, left chambers are enlarged and mitral annulus is dilated with lack of coaptation of leaflets. Transcatheter mitral valve repair technique has broadened the therapeutic range in the treatment of severe MR. The aim of this study was to review outcomes of MitraClip vs. medical treatment for functional MR. We also planned to review the concept of functional MR, assessment of the degree, prognosis and therapy options. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The Medline through PubMed database was used to search. The present review included manuscripts published between January 2009 and September 2019. Two authors independently screened titles and abstracts of all publications, and performed the selection of studies and data extraction. In the case of disagreements, consensus meetings reached the final decision. Inclusion criteria were: (I) randomized controlled trials and (II) works must compare MitraClip versus optimal medical treatment. Transcatheter mitral valve repair along optimal medical treatment has been compared with optimal medical therapy in two different randomized trials. In the COAPT trial, the MitraClip group showed a significant reduction in mortality and heart failure (HF) hospitalizations. In the MITRA-FR trial, no significant differences were observed between both groups. We reviewed important aspects of functional MR and performed a comprehensive review of both trials comparing them and focusing on their differences.

Sodium-Glucose Cotransporter-2 Inhibitors at Discharge from Cardiology Hospitalization Department: Decoding A New Clinical Scenario.

Sodium-glucose cotransporter-2 inhibitors (SGLT-2 inhibitors) are new glucose-lowering drugs (GLDs) with demonstrated cardiovascular benefits in patients with heart disease and type-2 diabetes mellitus (T2DM). However, their safety and efficacy when prescribed at hospital discharge are unexplored. This prospective, observational, longitudinal cohort study included 104 consecutive T2DM patients discharged from the cardiology department between April 2018 and February 2019. Patients were classified based on SGLT-2 inhibitor prescription and adjusted by propensity-score matching. The safety outcomes included discontinuation of GLDs; worsening renal function; and renal, hepatic, or metabolic hospitalization. The efficacy outcomes were death from any cause, cardiovascular death, cardiovascular readmission, and combined clinical outcome (cardiovascular death or readmission). The results showed that, the incidence rates of safety outcomes were similar in the SGLT-2 inhibitor or non-SGLT-2 inhibitor groups. Regarding efficacy, the SGLT-2 inhibitors group resulted in a lower rate of combined clinical outcomes (18% vs. 42%; hazard ratio (HR), 0.35; p = 0.02), any cause death (0% vs. 24%; HR, 0.79; p = 0.001) and cardiovascular death (0% vs. 17%; HR, 0.83; p = 0.005). No significant differences were found in cardiovascular readmissions. SGLT-2 inhibitor prescription at hospital discharge in patients with heart disease and T2DM was safe, well tolerated, and associated with a reduction in all-cause and cardiovascular deaths.

Cerebral protection devices for transcatheter aortic valve replacement.

Aortic stenosis is the most prevalent primary valve disease in developed countries. Its prevalence is increasing due to population aging. Transcatheter aortic valve replacement (TAVR) is a sterling therapy for symptomatic patients with severe aortic stenosis and high or intermediate surgery risk. The number of procedures has increased exponentially expanding to younger and lower risk patients. Despite new-generation TAVR devices and enhanced operator skills, cerebrovascular events (CVEs) carry on being one of the most severe complications, increasing morbi-mortality. CVE might be under reported because there are few studies with rigorous neurological clinical assessment. Several imaging studies show most of CVE after TAVR has a probable embolic etiology. The risk of CVE ranges from 2.7% to 5.5% at 30 days. As TAVR expands to younger and lower risk patients, the prevention of stroke plays an increasingly important role. Cerebral protection devices (CPD) were designed to reduce the risk of CVE during TAVR. This review describes the scientific evidence on CVE after TAVR and summarizes the performance and results of the main CPDs.

Contemporary differences between men and women with acute coronary syndromes: CIAM multicenter registry.

AIM: Differences exist in the diagnosis and treatment of acute coronary syndrome (ACS) between men and women. However, recent advancements in the management of ACSs might have attenuated this sex gap. We evaluated the status of ACS management in a multicenter registry in 10 tertiary Spanish hospitals. METHODS: We enrolled 1056 patients in our study, including only those with type 1 myocardial infarctions or unstable angina presumably not related to a secondary cause in an 'all-comers' design. RESULTS: The women enrolled (29%) were older than men (71.0 ±â€Š12.8 vs. 64.0 ±â€Š12.3, P = 0.001), with a higher prevalence of hypertension (71.0 vs. 56.5%, P < 0.001), insulin-treated diabetes (13.7 vs. 7.9%, P = 0.003), dyslipidemia (62.2 vs. 55.3%, P = 0.038), and chronic kidney disease (16.9 vs. 9.1%, P = 0.001). Women presented more frequently with back or arm pain radiation (57.3 vs. 49.7%, P = 0.025), palpitations (5.9 vs. 2.0%, P = 0.001), or dyspnea (33.0 vs. 19.4%, P = 0.001). ACS without significant coronary stenosis was more prevalent in women (16.8 vs. 8.1%, P = 0.001). There were no differences in percutaneous revascularization rates, but drug-eluting stents were less frequently employed in women (75.4 vs. 67.8%, P = 0.024); women were less often referred to a cardiac rehabilitation program (19.9 vs. 33.9%, P = 0.001). There were no significant differences in in-hospital complications such as thrombosis or bleeding. CONCLUSION: ACS presenting with atypical symptoms and without significant coronary artery stenosis is more frequent in women. Selection of either an invasive procedure or conservative management is not influenced by sex. Cardiac rehabilitation referral on discharge is underused, especially in women.

Miocardiopatía no compactada: una miocardiopatía con controversias / Non compaction cardiomyopathy: Review of a controversial entity

La miocardiopatía no compactada es una entidad heterogénea y compleja de la que existen todavía muchas dudas por resolver. Mientras que la American Heart Association la incluye entre las miocardiopatías de origen genético, la Sociedad Europea de Cardiología la considera como una miocardiopatía no clasificada. Puede presentarse tanto de forma esporádica como familiar, aislada o asociada con otras cardiopatías, afectar solo al ventrículo izquierdo o a ambos y puede, en ocasiones, aparecer como un fenotipo mixto en pacientes con otras miocardiopatías. A sus diferentes manifestaciones morfológicas se asocian también diferentes formas de presentación clínica e, incluso, la no compactación del ventrículo izquierdo puede estar desencadenada por otros procesos fisiológicos o patológicos. El objeto de esta revisión es una puesta al día de esta entidad y de sus controversias

Non-compaction cardiomyopathy is a heterogeneous and complex entity concerning which there are still many doubts to be resolved. While the American Heart Association includes it among genetic cardiomyopathies, the European Society of Cardiology treats it as an unclassified cardiomyopathy. It may present in a sporadic or familial form, isolated or associated with other heart diseases, affecting only the left ventricle or both and can sometimes appear as a mixed phenotype in patients with other cardiomyopathies. Different forms of clinical presentation are also associated with its different morphological manifestations, and even non-compaction of the left ventricle may be triggered by other physiological or pathological processes. The purpose of this review is an update of this entity and its controversies
