New severity criteria for tricuspid regurgitation in a broad population of "real life" patients: Prevalence and prognostic impact.

Introduction Our objective was to determine, in "real life" patients, the prevalence of massive and torrential regurgitation among patients diagnosed with severe tricuspid regurgitation (TR), as well as its impact on long-term prognosis. Methods In a single-center retrospective study, all patients with an echocardiographic diagnosis of severe TR attended at a tertiary care hospital of an European country from January 2008 to December 2017 were recruited. Images were analysed off-line to measure the maximum vena contracta (VC) and TR was classified into three groups: severe (VC ≥ 7 mm), massive (VC 14-20 mm), and torrential (VC ≥ 21 mm). The impact of this classification on the combined event of heart failure (HF) admission and all-cause death in follow-up was investigated. Results A total of 614 patients (70 ± 13 years, 72 % women) were included. 81.4 % had severe TR, 15.8 % massive TR, and 2.8 % torrential TR. The 5-year HF-free survival  was 42 %, 43 %, and 12 % (p = 0.001), for the different subgroups of severe TR, respectively. After adjusting for baseline characteristics, TR severity was an independent predictor of survival free of the combined end-point: HR 0.91 [95 % CI 0.70-1.18] p = 0.46, for massive TR; and HR 2.5 [95 % CI 1.49-4.21] p = 0.001, for torrential TR considering severe TR as reference. Conclusions The prevalence of massive and torrential TR is not negligible among patients with severe TR in real life. The prognosis is significantly worse for patients with torrential TR measured by the maximum VC.

The Worsening of Heart Failure with Reduced Ejection Fraction: The Impact of the Number of Hospital Admissions in a Cohort of Patients.

BACKGROUND: Worsening heart failure (WFH) includes heart failure (HF) hospitalisation, representing a strong predictor of mortality in patients with heart failure with reduced ejection fraction (HFrEF). However, there is little evidence analysing the impact of the number of previous HF admissions. Our main objective was to analyse the clinical profile according to the number of previous admissions for HF and its prognostic impact in the medium and long term. METHODS: A retrospective study of a cohort of patients with HFrEF, classified according to previous admissions: cohort-1 (0-1 previous admission) and cohort-2 (≥2 previous admissions). Clinical, echocardiographic and therapeutic variables were analysed, and the medium- and long-term impacts in terms of hospital readmissions and cardiovascular mortality were assessed. A total of 406 patients were analysed. RESULTS: The mean age was 67.3 ± 12.6 years, with male predominance (73.9%). Some 88.9% (361 patients) were included in cohort-1, and 45 patients (11.1%) were included in cohort-2. Cohort-2 had a higher proportion of atrial fibrillation (49.9% vs. 73.3%; p = 0.003), chronic kidney disease (36.3% vs. 82.2%; p < 0.001), and anaemia (28.8% vs. 53.3%; p = 0.001). Despite having similar baseline ventricular structural parameters, cohort-1 showed better reverse remodelling. With a median follow-up of 60 months, cohort-1 had longer survival free of hospital readmissions for HF (37.5% vs. 92%; p < 0.001) and cardiovascular mortality (26.2% vs. 71.9%; p < 0.001), with differences from the first month. CONCLUSIONS: Patients with HFrEF and ≥2 previous admissions for HF have a higher proportion of comorbidities. These patients are associated with worse reverse remodelling and worse medium- and long-term prognoses from the early stages, wherein early identification is essential for close follow-up and optimal intensive treatment.

The effects of obesity on longitudinal ventricular and atrial strain in a rural population of Spanish children and adolescents, evaluated by a new strain software.

BACKGROUND AND OBJECTIVES: Research on the relationship between body mass index (BMI) and strain values in children and adolescents is limited. Our aim was to analyse the relationship between BMI and strain values of both ventricles and left atrium in children and adolescents. METHODS: Both ventricles and left atrial strain values were compared among different BMI categories in children and adolescents from a town in the South of Spain. RESULTS: Of the 198 subjects, aged 6-17 years, 53% were of normal weight, 26% were overweight and 21% had obesity. Lower absolute values of left ventricular global longitudinal strain (25.9 ± 2.0% vs. 26.9 ± 2.2%, p = 0.002) and right ventricular free wall longitudinal strain (29.5 ± 4.2% vs. 30.8 ± 4.5%, p = 0.04) were found in subjects with obesity and overweight versus subjects with normal weight. A lower right ventricular four-chamber longitudinal strain was also observed in males with obesity and overweight (24.8 ± 3.3% vs. 26.4 ± 3.6%, p = 0.03). Statistically significant negative correlations of BMI were found for all ventricular, but not atrial, strain values in univariate analysis. This association turned non-significant for right ventricular four-chamber longitudinal strain in multivariate analysis. CONCLUSIONS: Utilizing this new strain software, children and adolescents with high BMI were associated with significantly lower values for left and right ventricular free wall longitudinal strain, without impact in left atrial strain.

Risk scores for predicting incident heart failure admission in patients with chronic coronary syndromes: Validation in a prospective, monocentric, long-term, cohort study.

BACKGROUND: Heart failure (HF) admission in chronic coronary syndrome (CCS) patients has a prognostic impact. Stratification schemes have been described for predicting this endpoint, but none of them has been externally validated. OBJECTIVES: Our aim was to develop point scores for predicting incident HF admission with data from previous studies, to perform an external validation in an independent prospective cohort and to compare their discriminative ability for this event. METHODS: Independent predictive variables of HF admission in CCS patients without baseline HF were selected from four previous prospective studies (CARE, PEACE, CORONOR and CLARIFY), generating scores based on the relative magnitude of the coefficients of Cox of each variable. Finally, the scores were validated and compared in a monocentric prospective cohort. RESULTS: The validation cohort included 1212 patients followed for up to 17 years, with 171 patients suffering at least one HF admission in the follow-up. Discriminative ability for predicting HF admission was statistically significant for all, and paired comparisons among them were all nonsignificant except for CORONOR score was superior to CLARIFY score (C-statistic 0.73, 95%CI 0.69-0.76 vs. 0.69, 95% CI 0.65-0.73; p = 0.03). CONCLUSION: All tested scores showed significant discriminative ability for predicting incident HF admission in this independent validation study. Their discriminative ability was similar, with significant differences only between the two scores with higher and lower performance.

Long-Term Prognostic Impact of Sex in Patients with Chronic Coronary Syndrome: A 17-Year Prospective Cohort Study.

Background: Women and men with chronic coronary syndrome (CCS) have different clinical features and management, and studies on mid-term prognosis have reported conflicting results. Our objective was to investigate the impact of the female sex in the prognosis of the disease in the very long term. Methods and Results: We investigated differential features and very long-term prognosis in 1268 consecutive outpatients with CCS (337 [27%] women and 931 [73%] men). Women were older than men, more likely to have hypertension, diabetes, angina, and atrial fibrillation, and less likely to be exsmoker/active smoker and to have been treated with coronary revascularization (p < 0.05 for all). The prescription of statins, antiplatelets, and betablockers was similar in both groups. After up to 17 years of follow-up (median = 11 years, interquartile range = 4-15 years), cumulative incidences of acute myocardial infarction (10.2% vs. 11.8%) or stroke (11% vs. 10%) at median follow-up were similar, but the risks of major cardiovascular events (acute myocardial infarction, stroke, or cardiovascular death, 41.2% vs. 33.6%), hospital admission for heart failure (20.9% vs. 11.9%), or cardiovascular death (32.3% vs. 22.1%) were significantly higher for women (p < 0.0005), with a nonsignificant trend to higher overall mortality (45.2% vs. 39.1%, p = 0.07). However, after multivariate adjustment, all these differences disappeared. Conclusion: Although women and men with CCS presented a different clinical profile, and crude rates of major cardiovascular events, heart failure and cardiovascular death were higher in women, female sex was not an independent prognostic factor in this study with up to 17 years of follow-up.

The Role of Left Atrial Longitudinal Strain in the Diagnosis of Acute Cellular Rejection in Heart Transplant Recipients.

Our aim was to investigate the role of left atrial longitudinal strain (LALS) in the non-invasive diagnosis of acute cellular rejection (ACR) episodes in heart transplant (HTx) recipients. Methods: We performed successive echocardiographic exams in 18 consecutive adult HTx recipients in their first year after HTx within 3 h of the routine surveillance endomyocardial biopsies (EMB) in a single center. LALS parameters were analyzed with two different software. We investigated LALS association with ACR presence, as well as inter-vendor variability in comparable LALS values. Results: A total of 147 pairs of EMB and echo exams were carried out. Lower values of LALS were significantly associated with any grade of ACR presence. Peak atrial longitudinal strain (PALS) offered the best diagnostic value for any grade of ACR, with a C statistic of 0.77 using one software (95% CI 0.68−0.84, p < 0.0005) and 0.64 with the other (95% CI 0.54−0.73, p = 0.013) (p = 0.02 for comparison between both curves). Reproducibility between comparable LALS parameters was poor (intraclass correlation coefficients were 0.60 for PALS, 95% CI 0.42−0.73, p < 0.0005; and 0.42 for PALS rate, 95% CI −0.13−0.68, p < 0.0005). Conclusions: LALS variables might be a sensitive marker of ACR in HTx recipients, principally discriminating between those studies without rejection and those with any grade of ACR. Inter-vendor variability was significant.

Alteraciones electrocardiográficas y necesidad de marcapasos en amiloidosis cardiaca: análisis de 58 casos / Electrocardiographic features and need for pacemaker in cardiac amyloidosis: Analysis of 58 cases

ObjetivoEn la amiloidosis cardiaca (AC) el material amiloide puede depositarse en diferentes estructuras cardiacas pudiendo producir diferentes alteraciones electrocardiográficas. El objetivo fue describir qué alteraciones electrocardiográficas son más frecuentes en pacientes con AC, analizando su impacto en la necesidad de marcapasos.MetodosEstudio retrospectivo que incluye pacientes diagnosticados de AC por cadenas ligeras (AC-AL) y AC por transtirretina (AC-TTR), entre enero-2013 y marzo-2021. Se analizó el ritmo basal, el porcentaje con patrón de seudoinfarto, bajo voltaje o alteraciones de la conducción; también se analizó el impacto en la necesidad de marcapasos definitivo.ResultadosSe incluyeron 58 pacientes con AC (20 AC-AL, 38 AC-TTR). Varones (69%), 21 (36%) tenían FA al diagnóstico. El 60% tenía patrón de seudoinfarto, el 35% bajo voltaje y un 22% tenían criterios de hipertrofia ventricular. Dos tercios tenían algún trastorno de conducción: bloqueo auriculoventricular de primer grado, 18 pacientes (31%); 12 bloqueo completo de rama derecha (BCRD), 3 bloqueo completo de rama izquierda (BCRI) y 25 con un hemibloqueo de rama. No hubo diferencias entre AC-AL y AC-TTR. Los pacientes con AC-TTR tuvieron mayor necesidad de marcapasos en el seguimiento (39±40 meses). El bloqueo completo de rama (BCR) fue un predictor de necesidad de marcapasos permanente (HR: 23,43; IC 95%: 4,09-134,09; p=0,01).ConclusionesLas alteraciones electrocardiográficas en pacientes diagnosticados de AC son heterogéneas, siendo la más frecuente la presencia de trastornos de conducción, el patrón de seudoinfarto, seguido del de bajo voltaje. Los pacientes con cualquier BCR en el electrocardiograma basal son más propensos a precisar marcapasos en el seguimiento, sobre todo en AC-TTR. (AU)

AimAmyloidosis is a disease in which amyloid fibrils can be deposited in different cardiac structures, and several electrocardiographic abnormalities can be produced by this phenomenon. The objective of this study was to describe the most common basal electrocardiographic alterations in patients diagnosed with cardiac amyloidosis (CA) and to determine if these abnormalities have an impact on the need of pacemaker.MethodsThis retrospective study included patients who had an established diagnosis of CA [light-chain cardiac amyloidosis (LA-CA) or transthyretin cardiac amyloidosis (TTR-CA)] between January 2013 and March 2021. The baseline heart rate, the percentage of patients with a pseudo-infarct pattern, low-voltage pattern or cardiac conductions disturbances, and the impact of these factors on the need of pacemaker were analysed.ResultsFifty-eight patients with CA (20 with LA-CA and 38 with TTR-CA) were included, and the majority were male (69.0%). Twenty-one patients had atrial fibrillation (AF) at diagnosis. Thirty-five patients had a pseudo-infarct pattern, 35% had a low-voltage pattern, and 22% had criteria for ventricular hypertrophy. Two hirds had a conduction disorder: 18 patients with first degree atrioventricular block, 12 right bundle branch block, 3 left bundle branch block and 25 with a branch hemiblock. There were no differences between LA-CA and TTR-CA. Patients with TTR-CA had a greater need for pacemakers in the folow-up (39±40 meses). Bundle branch block was a predictor of the need for a permanent pacemaker (HR: 23.43; CI 95%: 4.09.134.09; P=.01).ConclusionsElectrocardiographic abnormalities in patients diagnosed wich CA are heterogeneus. Most frecuent is the presence of conduction disorders, the pseudoinfarction pattern, followed by the low voltage pattern. Patients with any bundle branch block at the baseline electrocardiogram need more frecuent to require a pacemaker during follow-up, especially in TTR-CA. (AU)

The Assessment of Myocardial Longitudinal Strain in a Paediatric Spanish Population Using a New Software Analysis.

BACKGROUND: Two-dimensional speckle-tracking echocardiography (2DSTE) has been present for years. However, it is underutilized due to the expertise and time requirements for its analysis. Our aims were to provide strain values in a paediatric Spanish population and to assess the feasibility and reproducibility of a new strain software analysis in our environment. METHODS: A cross-sectional study of 156 healthy children aged 6 to 17 years. Longitudinal strain (LS) analysis of the left ventricle, right ventricle, and left atrium was performed. Feasibility and reproducibility were assessed. The associations of clinical and echocardiographic variables with strain values were investigated by multivariate analysis. RESULTS: Mean age was 11 ± 3 years (50% female). Feasibility of LS measurement ranged from 94.2% for left ventricle global LS (LVGLS) to 98.1% for other chamber strain parameters. Strain values were 26.7 ± 2.3% for LVGLS; 30.5 ± 4.4% and 26.9 ± 4% for right ventricle free wall LS (RVFWLS) and four chambers view LS (RV4CLS) respectively; and 57.8 ± 10.5%, 44.9 ± 9.5%, and 12.9 ± 5.5% for left atrium LS reservoir phase (LALSr), conduct phase (LALScd) and contraction phase (LALSct), also respectively. Body surface area (BSA) and age presented a negative correlation with strain values. Higher values were found in females than in males, except for LALScd. Excellent intra- and inter-observer reproducibility were found for right and left ventricular strain measurement, with intraclass correlation coefficients (ICC) ranging from 0.88 to 0.98, respectively. In conclusion, we described strain values in a healthy Spanish paediatric population. LS assessment by this new strain analysis software by semi-automatic manner was highly feasible and reproducible.

Tissue Doppler velocities for ruling out rejection in heart transplant recipients in the context of myocardial strain imaging: a multivariate, prospective, single-center study.

To investigate the value of tissue Doppler velocities for ruling out treatment-requiring acute cellular rejection (TR-ACR), in the context of myocardial deformation analysis performed by means of speckle tracking echocardiography. We performed serial echocardiograms in 37 heart transplant recipients in their first year post-transplantation within 3 h of the routine surveillance endomyocardial biopsies (EMB). The association of the sum of lateral mitral annulus systolic (s') and early diastolic (e') velocities, in absolute values, measured by tissue Doppler echocardiography (s'+ e'), with TR-ACR (ACR grade ≥ 2R) was investigated by multivariate analysis, including classic echocardiographic parameters and myocardial deformation variables. A total of 251 pairs of EMB and echo exams were performed, 35 (14%) with rejection grade ≥ 2R (TR-ACR). s' + e' was independently associated to TR-ACR (OR 0.80, 95%CI 0.72-0.89, p < 0.0005), with a C statistic of 0.79 (95%CI 0.71-0.87, p < 0.0005) by ROC curve analysis. An s'+ e' value ≥ 23 cm/s, present in 43% of studies, had a negative predictive value of 98% for ruling out TR-ACR. Moreover, in the same patients, s'+ e' significantly decreased when TR-ACR occurred after a study without this condition (- 3.7 ± 3.3 cm/s, p = 0.003), but it was similar when rejection status was the same in the present versus the previous study. A drop in s'+ e' value < 2.7 cm/s from the previous echocardiogram, had a 99% negative predictive value for ruling out TR-ACR. Tissue Doppler velocities, a widely available echo parameter, were found to be a valuable marker for ruling out TR-ACR in this multivariate study which included myocardial deformation variables.

Supervivencia a largo plazo de una población española con cardiopatía isquémica estable: el registro CICCOR / Long-term survival in a Spanish population with stable ischemic heart disease. The CICCOR registry

Introducción y objetivos: La información sobre el pronóstico de la cardiopatía isquémica crónica (CIC) es escasa. El objetivo es analizar los predictores de la mortalidad y la supervivencia a largo plazo de estos pacientes. Métodos: Estudio de cohortes prospectivo y monocéntrico que reclutó a 1.268 pacientes con CIC desde enero de 2000 hasta febrero de 2004. Se registraron los fallecimientos durante el seguimiento. Se compararon las tasas de mortalidad total y cardiovascular ajustadas con la población española. Se investigó la asociación de variables basales con la mortalidad. Resultados: La media de edad fue 68+/-10 años; el 73% eran varones. Tras 17 años de seguimiento máximo (mediana, 11 años), murieron 629 pacientes (50%). La edad (HR=1,08; IC95%, 1,07-1,11; p<0,001), la diabetes (HR=1,36; IC95%, 1,14-1,63; p <0,001), la frecuencia cardiaca (HR=1,01; IC95%, 1,00-1,02; p <0,001), la fibrilación auricular (HR=1,61; IC95%, 1,22-2,14); p=0,001), las alteraciones electrocardiográficas (HR=1,23; IC95%, 1,02-1,49; p=0,02) y el tabaquismo (HR=1,85; IC95%, 1,31-2,80; p=0,001) han resultado predictores independientes de la mortalidad total. La tasa de mortalidad total fue mayor que en la población española (47,81 frente a 36,29/1.000 pacientes/año; razón de mortalidad estandarizada=1,31; IC95%, 1,21-1,41). La tasa de mortalidad cardiovascular fue 15,25 frente a 6,94/1.000 pacientes/año de la población general (razón de mortalidad estandarizada=2,19; IC95%, 1,88-2,50). Conclusiones: En esta muestra de pacientes con CIC, la tasa de mortalidad fue significativamente mayor que en la población general. Las variables clínicas identifican a los pacientes con mayor riesgo de muerte en el seguimiento

Introduction and objectives: Data are lacking on the long-term prognosis of stable ischemic heart disease (SIHD). Our aim was to analyze long-term survival in patients with SIHD and to identify predictors of mortality. Methods: A total of 1268 outpatients with SIHD were recruited in this single-center prospective cohort study from January 2000 to February 2004. Cardiovascular and all-cause death during follow-up were registered. All-cause and cardiovascular mortality rates were compared with those in the Spanish population adjusted by age, sex, and year. Predictors of these events were investigated. Results: The mean age was 68+/-10 years and 73% of the patients were male. After a follow-up lasting up to 17 years (median 11 years), 629 (50%) patients died. Independent predictors of all-cause mortality were age (HR, 1.08; 95%CI, 1.07-1.11; P <.001), diabetes (HR, 1.36; 95%CI, 1.14-1.63; P <.001), resting heart rate (HR, 1.01; 95%CI, 1.00-1.02; P <.001), atrial fibrillation (HR, 1.61; 95%CI, 1.22-2.14; P=.001), electrocardiographic changes (HR, 1.23; 95%CI, 1.02-1.49; P=.02) and active smoking (HR, 1.85; 95%CI, 1.31-2.80; P=.001). All-cause mortality and cardiovascular mortality rates were significantly higher in the sample than in the general Spanish population (47.81/1000 patients/y vs 36.29/1000 patients/y (standardized mortality rate, 1.31; 95%CI, 1.21-1.41) and 15.25/1000 patients/y vs 6.94/1000 patients/y (standardized mortality rate, 2.19; 95%CI, 1.88-2.50, respectively). Conclusions: The mortality rate was higher in this sample of patients with SIHD than in the general population. Several clinical variables can identify patients at higher risk of death during follow-up

Prosthesis-patient mismatch after transcatheter aortic valve replacement: prevalence and medium term prognostic impact.

Prosthesis-patient mismatch (PPM) occurs when the effective orifice area of the prosthesis is too small in relation to the patient's body surface area. There are few data available on the frequency and prognostic impact of PPM after transcatheter aortic valve implantation (TAVI). Our aim was to determine the prevalence of PPM and to investigate its association with medium-term clinical course of patients undergoing TAVI. We included 185 patients undergoing TAVI (79 ± 5 years, 49% male, 98% CoreValve) between April-2008 and December-2014. The effective orifice area (EOA) was determined by transthoracic echocardiography prior and after the procedure. We defined PPM as indexed EOA ≤ 0.85 cm2/m2 (severe PPM if ≤ 0.65 cm2/m2). All cause death, stroke and hospitalization for heart failure were considered as major clinical events. 45 patients (24%) showed PPM (severe 11 patients, 6%). PPM was associated with a higher EuroSCORE (OR 1.06, IC 95% 1.01-1.12, p = 0.03), body surface area ≥ 1.72 m2 (OR 3.58, IC 95% 1.30-9.87, p = 0.01) and small aortic annulus (OR 0.73, IC 95% 0.55-0.92, p = 0.03); and severe PPM with small prostheses size (OR 17.79, IC 95% 1.87-169.78, p = 0.012). The mean event-free survival was 34 ± 26 months. Patients with severe PPM showed lower rates of event free survival than the rest of the series (52% vs. 84%, p = 0.04) at 34 months follow up. In our series, PPM was present in a quarter of the patients after TAVI. Higher EuroSCORE, smaller prosthesis size, larger body surface area and smaller aortic annulus diameter were associated with PPM. Severe PPM was an independent factor associated with major events at medium-term follow up.

CONCLUSIONS: The mortality rate was higher in this sample of patients with SIHD than in the general population. Several clinical variables can identify patients at higher risk of death during follow-up.

Endocarditis infecciosa sobre válvula nativa del lado izquierdo: influencia de la edad y de cardiopatía previa / Left-sided native valve infective endocarditis: Influence of age and the presence of underlying heart disease

Introducción y objetivos: La epidemiología de la endocarditis infecciosa sobre válvula nativa izquierda (EIVNI) se ha modificado, consecuencia del aumento en la edad media de los pacientes. El objetivo de nuestro estudio es analizar la influencia de la edad y la presencia de una cardiopatía predisponente previa en el pronóstico de estos pacientes. Métodos: Analizamos 257 casos consecutivos de EIVNI en función de su edad, tanto en la serie global como en el subgrupo de pacientes sin cardiopatía predisponente. Resultados: La edad media fue de 54,6 (18,6) años. Existió un aumento en la proporción de pacientes de edad igual o mayor a 70 años entre 1987-2000 y 2001-2014 (9,8 frente a 34,8%, p < 0,001), que presentaban una mayor prevalencia de valvulopatía degenerativa (50 frente a 22,8%), ausencia de cardiopatía (50 frente a 39,9%), p < 0,001, casos relacionados con atención sanitaria (41,8 frente a 23,6%, p = 0,016), menor tasa de cirugía (43,7 frente a 63,8%, p = 0,005) y mayor mortalidad hospitalaria (39,1 frente a 20,7%, p = 0,003), sin diferencias respecto a comorbilidades. Los pacientes sin cardiopatía también presentaron una mortalidad hospitalaria más elevada (47 frente a 22%, p = 0,01). La edad igual o mayor a 70 años constituye un predictor independiente de mortalidad en pacientes con EIVNI (OR 2,53, IC 95% 1,24-5,15, p = 0,011), igual que en aquellos que no presentan cardiopatía (OR 3,98, IC 95% 1,49-10,62, p = 0,006). Conclusiones: Los pacientes que tienen una edad igual o mayor a 70 años con un episodio de EIVNI son cada vez más frecuentes y presentan peor pronóstico, con una tasa menor de cirugía y mayores tasas de mortalidad hospitalaria (AU)

Introduction and objectives: Left-sided native valve infective endocarditis (LNVIE) epidemiology has been modified as a result of the increase in average age. The aim of our study is to analyze the influence of age and the presence of predisposing heart disease in the prognosis of these patients. Methods: We analyzed a series of 257 cases of LNVIE depending on their age (greater than or equal to 70 years old), both in the overall series and in the subgroup of patients without predisposing heart disease. Results: Mean age was 54.6 (18.6) years. There was an increase in the percentage of cases of older patients between 1987-2000 and 2001-2014 (9.8 vs. 34.8%, P < .001). These patients present higher prevalence of degenerative valves (50 vs. 22.8%) or not predisposing heart disease (50 vs. 39.9%), P < .001, health-care associated episodes (41.8 vs. 23.6%, P = .016), lower rate of surgery (43.7 vs. 63.8%, P = .005) and higher in-hospital mortality (39.1 vs. 20.7%, P = .003), with no differences in comorbidities. Older patients who did not have predisposing heart disease also suffered higher in-hospital mortality (47 vs. 22%, P = .01).Age greater than or equal to 70 years old is an independent predictor of mortality in patients with LNVIE (OR 2.53, 95% CI 1.24-5.15, P = .011), as in those without previous heart disease (OR 3.98, 95% CI 1.49-10.62, P = .006). Conclusions: Patients of age greater than or equal to 70 years old and who suffer an LNVIE are becoming more frequent and have a worse prognosis with a lower rate of surgery and higher rates of in-hospital mortality (AU)

Mitral regurgitation during transcatheter aortic valve implantation: the same complication with a different mechanism.

AIMS: Mitral regurgitation (MR) is a complication that may occur during transcatheter aortic valve implantation (TAVI) in a certain percentage of cases and may require different treatments depending on the mechanism. Our purpose was to describe the occurrence rate of this complication during TAVI with the CoreValve prosthesis, as well as to assess the usefulness of transesophageal echocardiogram (TEE) in the detection of the mechanism of MR. METHODS AND RESULTS: We analyzed a total of 129 cases of severe aortic stenosis treated with CoreValve prosthesis from June 2008 to October 2011. We defined a significant MR after TAVI as grade III MR or higher, considering either the new appearance of MR or the worsening of a preexisting MR, as assessed by both TEE and angiography. In our series, there was a total of 11 cases of significant MR after TAVI (8.5%). Angiography detected 100% of the MR cases, but was unable to determine the mechanism of MR in any case. TEE, on the other hand, determined 100% of the MR cases, and determined that 1 case was caused by mechanical asynchrony due to a new left bundle branch block, 3 cases were due to an aortic prosthesis impingement on the anterior mitral leaflet, 2 cases were due to the appearance of a systolic anterior movement of the anterior mitral leaflet with dynamic obstruction of the left ventricular outflow tract, 1 case was caused by a commissural tearing of the valve, and 4 cases were explained by a "functional" mechanism, probably due to transient damage of the subvalvular mitral apparatus by the delivery system. All cases had an MR grade II or less as evidenced by transthoracic echocardiography at discharge. Surgery was not required in any case. Knowledge of the mechanism of MR made it possible to provide the best treatment option in each case. CONCLUSION: There is a certain percentage of patients treated with CoreValve prosthesis who develop significant MR during the procedure. TEE, unlike angiography, can define the very diverse mechanisms of MR in 100% of cases, and elucidates the best approach to this complication. Surgery was not required in any case.

Monitoring complex secundum atrial septal defects percutaneous closure with real time three-dimensional echocardiography.

BACKGROUND: Atrial septal defect (ASD) is one of the most common congenital heart diseases. Nowadays, percutaneous closure is considered the treatment of choice in most of secundum ASDs. Assessment of the defect and procedure monitoring have been usually performed by angiographic balloon-sizing and/or two-dimensional (2D) transesophageal echocardiography. However, in complex ASDs these techniques might be inaccurate. METHODS: From January 2009 to January 2011 all adult patients with complex ASDs submitted for percutaneous closure were selected. Those defects, where shunts were present through a device previously implanted on the atrial septum or through multiperforated septums, were considered complex ASDs. Two-dimensional transesophageal echocardiography and real time three-dimensional (3D) echocardiography were performed simultaneously during the percutaneous closure procedure. Number of orifices, relationships between the defect, catheter, and device, as well as residual shunt were assessed. RESULTS: Seven patients were included. Five patients had a multiperforated septum and in two cases the defect in the septum was through a previously implanted device. In all cases, 3D echocardiography was superior to 2D echocardiography in relation to the assessment of the relationship between the defect and the catheter or the device. Mechanisms responsible for residual shunts through a device were also better assessed by 3D echocardiography. CONCLUSION: Three-dimensional echocardiography is a safe and useful technique when monitoring percutaneous closure of ASDs, showing relevant advantages over 2D echocardiography.
