RESUMEN
INTRODUCTION AND OBJECTIVES: Vaccines against SARS-CoV-2 have been a major scientific and medical achievement in the control of the COVID-19 pandemic. However, very infrequent cases of inflammatory heart disease have been described as adverse events, leading to uncertainty in the scientific community and in the general population. METHODS: The Vaccine-Carditis Registry has included all cases of myocarditis and pericarditis diagnosed within 30 days after COVID-19 vaccination since August 1, 2021 in 29 centers throughout the Spanish territory. The definitions of myocarditis (probable or confirmed) and pericarditis followed the consensus of the Centers for Disease Control and the Clinical Practice Guidelines of the European Society of Cardiology. A comprehensive analysis of clinical characteristics and 3-month evolution is presented. RESULTS: From August 1, 2021, to March 10, 2022, 139 cases of myocarditis or pericarditis were recorded (81.3% male, median age 28 years). Most cases were detected in the 1st week after administration of an mRNA vaccine, the majority after the second dose. The most common presentation was mixed inflammatory disease (myocarditis and pericarditis). 11% had left ventricular systolic dysfunction, 4% had right ventricular systolic dysfunction, and 21% had pericardial effusion. In cardiac magnetic resonance studies, left ventricular inferolateral involvement was the most frequent pattern (58%). More than 90% of cases had a benign clinical course. After a 3-month follow-up, the incidence of adverse events was 12.78% (1.44% mortality). CONCLUSIONS: In our setting, inflammatory heart disease after vaccination against SARS-CoV-2 predominantly affects young men in the 1st week after the second dose of RNA-m vaccine and presents a favorable clinical course in most cases.

Background: New percutaneous techniques for the management of acute pulmonary embolism (PE) are emerging, but there is lack of data regarding the approach of mobile thrombus in the right chambers, with the added risk of potential thrombus dislodgement that may prevent from mechanical circulatory support devices to be implanted in unstable patients. Case summary: We present the case of a 65-year-old male with cardiogenic shock of unknown aetiology, severe biventricular dysfunction, and large mobile thrombus in the right atrium. Mechanical circulatory support devices could not be implanted, and current thromboaspiration systems were either too small or not available at that time. However, the patient's condition deteriorated rapidly with thrombus in transit, hence, a novel approach was required: using a deflectable 14â Fr sheath, directional thrombectomy was performed, achieving complete extraction of the thrombi and allowing for circulatory support with extracorporeal membrane oxygenation (ECMO) to be implanted with outstanding results and progressive weaning of all intensive care measures. Discussion: Despite the growing interest in the development of percutaneous strategies for acute PE, there is no evidence-based guidelines regarding the treatment of mobile right heart thrombus. Even though some cases of percutaneous right heart thrombectomy have been reported, it is still a challenging scenario, given the potential risk of thrombus dislodgement and atrial perforation. We describe a novel technique of percutaneous directional thrombectomy in a patient with cardiogenic shock of unknown aetiology and large mobile thrombi in the right atrium as a bridge to ECMO proving to be a feasible alternative to treat thrombus in transit.
RESUMEN
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 (71.0â±â12.8 vs. 64.0â±â12.3, Pâ=â0.001), with a higher prevalence of hypertension (71.0 vs. 56.5%, Pâ<â0.001), insulin-treated diabetes (13.7 vs. 7.9%, Pâ=â0.003), dyslipidemia (62.2 vs. 55.3%, Pâ=â0.038), and chronic kidney disease (16.9 vs. 9.1%, Pâ=â0.001). Women presented more frequently with back or arm pain radiation (57.3 vs. 49.7%, Pâ=â0.025), palpitations (5.9 vs. 2.0%, Pâ=â0.001), or dyspnea (33.0 vs. 19.4%, Pâ=â0.001). ACS without significant coronary stenosis was more prevalent in women (16.8 vs. 8.1%, Pâ=â0.001). There were no differences in percutaneous revascularization rates, but drug-eluting stents were less frequently employed in women (75.4 vs. 67.8%, Pâ=â0.024); women were less often referred to a cardiac rehabilitation program (19.9 vs. 33.9%, Pâ=â0.001). 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.

PURPOSE: Left ventricular (LV) mechanics are impaired in patients with severe aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has become a widespread technique for patients with severe AS considered inoperable or high risk for open surgery. This procedure could have a positive impact in LV mechanics. The aim of the study was to evaluate the effect of TAVR on LV function recovery, as assessed by myocardial deformation parameters, both immediately and in the long term. METHODS: One-hundred nineteen consecutive patients (81.2 ± 6.9 years, 50.4% female) from 10 centres in Europe with severe AS who successfully underwent TAVR with either a self-expanding CoreValve (Medtronic, Minneapolis, MN, USA) or a mechanically expanded Lotus valve (Boston Scientific, Natick, MA, USA) were enrolled in a prospective observational study. A complete echocardiographic examination was performed prior to device implantation, before discharge and 1 year after the procedure, including the assessment of LV strain using standard 2D images. RESULTS: Between baseline and discharge, only a modest but statistically significant improvement in GLS (global longitudinal strain) could be seen (GLS% -14.6 ± 5.0 at baseline; -15.7 ± 5.1 at discharge, p = 0.0116), although restricted to patients in the CoreValve group; 1 year after the procedure, a greater improvement in GLS was observed (GLS% -17.1 ± 4.9, p < 0.001), both in the CoreValve and the Lotus groups. CONCLUSIONS: Immediate and sustained improvement in GLS was appreciated after the TAVR procedure. Whether this finding continues to be noted in a more prolonged follow-up and its clinical implications need to be assessed in further studies.

Left atrium (LA) size has an important role in determining prognosis and risk stratification in hypertrophic cardiomyopathy (HCM). Cardiovascular magnetic resonance myocardial feature tracking (CMR-FT) is a novel technique for the quantification of LA function. Our aim was first to evaluate LA function by CMR-FT and volumetric analysis in patients with HCM; and secondly we sought to determine the association of LA-longitudinal strain (LA-LS) with major cardiovascular outcomes, particularly all cause mortality and heart failure. 75 patients with HCM and 75 control subjects underwent a conventional CMR study including assessment of LA function by CMR-FT (LA-LS) and volumetric analysis. A primary endpoint of all-cause mortality and secondary combined endpoint of hospital admission related to heart failure, lethal ventricular arrhythmias or cardiovascular death were defined. Compared to controls, LA-LS and all volumetric indices of LA function were significantly impaired in HCM even in patients with normal LA volume and normal LV filling pressures. LA-LS showed moderate-high correlation with LA-emptying fraction (total, active and passive LA-EF, r = 0.68, r = 0.67, r = 0.31, p < 0.001 for all) and with parameters of diastolic function (E/é, r = 0.4, p < 0.001). The age, minimum LA volume and % of LGE were independent predictors of LA-LS (p < 0.01 for all). During a mean follow-up of 3.3 ± 1.2 years LA-LS was associated with the primary (HR: 0.85 (0.73-0.98), p = 0.02) and the secondary end-point (HR: 0.88 (0.82-0.96), p = 0.003). LA-LS by CMR-FT provides accurate measurements of LA function in HCM patients. LA-LS may become a novel potential predictor of poor cardiac outcomes, particularly cardiovascular mortality and HF.

BACKGROUND: Left ventricular (LV) mechanics are impaired in patients with severe aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) has become a widespread technique for patients with severe AS considered inoperable or high risk for traditional open-surgery. This procedure could have a positive impact in LV mechanics. The aim of this study was to evaluate the immediate effect of TAVR on LV function recovery, as assessed by myocardial deformation parameters. METHODS: One-hundred twelve consecutive patients (81.4 ± 6.4 years, 50% female) from 10 centres in Europe with severe AS who successfully underwent TAVR with either a self-expanding CoreValve (Medtronic, Minneapolis, MN) or a mechanically expanded Lotus valve (Boston Scientific, Natick, MA) were enrolled in a prospective multi-center study. A complete echocardiographic examination was performed at baseline and immediately before discharge, including the assessment of LV strain using standard two-dimensional images. RESULTS: Echocardiographic examination with global longitudinal strain (GLS) quantification could be obtained in 92 patients, because of echocardiographic and logistic reasons. Between examinations, a modest statistically significant improvement in GLS could be seen (GLS% -15.00 ± 4.80 at baseline;-16.15 ± 4.97 at discharge, p = 0.028). In a stratified analysis, only women showed a significant improvement in GLS and a trend towards greater improvement in GLS according to severity of systolic dysfunction as measured by LV ejection fraction could be noted. CONCLUSIONS: Immediate improvement in GLS was appreciated after TAVR procedure. Whether this finding continues to be noted in a more prolonged follow-up and its clinical implications need to be assessed in further studies.

BACKGROUND: Interstitial fibrosis, myocardial fiber disarray and non-uniform shortening are common histological features of hypertrophic cardiomyopathy (HCM). The degree of LV hypertrophy and fibrosis are postulated to contribute to the impairment of myocardial shortening. Cardiovascular magnetic resonance myocardial (CMR) feature tracking (CMR-FT) has emerged as a robust method that provides quantitative measurements of myocardial deformation. Our aim was first to evaluate LV strain parameters in HCM by CMR-FT and their dependence on both functional parameters and late gadolinium enhancement (LGE); and secondly we sought to determine their association with major cardiovascular outcomes. METHODS AND RESULTS: 74 patients with HCM and 75 controls subjects underwent a CMR study including LGE imaging. Global peak longitudinal, circumferential and radial systolic strain values (GLS, GCS, GRS) were measured by CMR-FT. A primary endpoint of all-cause mortality and secondary combined endpoint of hospital admission related to heart failure, lethal ventricular arrhythmias or cardiovascular death were defined. Patients with HCM showed attenuation of all LV strain values (p<0.001). Multivariate analysis showed that both LV hypertrophy and %of LGE were independent predictors of attenuated LV strains. All systolic LV strain parameters were impaired in patients with primary and secondary endpoints (follow up time: 25.6±9.9months, p<0.05 and p<0.01 respectively). Abnormal GLS, GCS and GRS were significantly associated with primary and secondary endpoints. CONCLUSION: Both LV hypertrophy and fibrosis contribute to the impairment of LV myocardial mechanics in HCM. In this population, reduced LV strain is associated with poor cardiac outcomes, particularly cardiovascular mortality and HF.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) remains the most common cause of sudden cardiac death (SCD) in the young; however, current strategies do not identify all HCM patients at risk. A novel validated algorithm was proposed by the last European Society of Cardiology guidelines to guide implantable cardioverter-defibrillator (ICD) therapy. Recently, extensive myocardial fibrosis was independently associated with increased risk of SCD events. This study aimed to establish the relation between myocardial fibrosis (late gadolinium enhancement [LGE] extension) and the novel SCD risk-prediction model in a real population of HCM to evaluate its potential additional value in the different risk groups. HYPOTHESIS: There is a significant association between LGE extension and the novel SCD risk calculator that may help conflicting ICD decisions. METHODS: Seventy-seven patients with HCM underwent routine clinical evaluation, echocardiography, and cardiac magnetic resonance study. Their SCD risk at 5 years was calculated using the new model. RESULTS: Extension of LGE positively correlated with SCD risk prediction (r = 0.7, P < 0.001). Low-, intermediate-, and high-risk groups according to the model showed significantly different extent of LGE (5% ± 6% vs 18% ± 9% vs 17% ± 4%; P < 0.001). Four patients (6%) in the low-risk group and 5 (62%) in the intermediate-risk group showed extensive areas of LGE. All patients except 1 (86%) at highest risk (n = 6) showed extensive areas of LGE. CONCLUSIONS: LGE extension is concordant with the novel SCD-risk model defining low- and high-risk groups; it may provide additional information, allowing better discrimination to support implantable cardioverter-defibrillator decision. LGE quantification holds promise for SCD stratification in HCM.
