RESUMO

This thematic review focuses on recently proposed classification of stages in pronounced aortic stenosis based on the prevalence of extravalvular cardiac damage and its modified variant designed for asymptomatic patients. The review presents studies, which analyzed the predictive significance of the proposed classification. The use of this classification allows predicting the course of disease in patients with pronounced aortic stenosis in valve replacement. The classification is based on routinely used structural and functional echocardiographic signs with already proven predictive values with respect of adverse events in patients after aortic valve replacement. The review discusses limitations of the classification for pronounced aortic stenosis stages based on the prevalence of extravalvular cardiac damage.

RESUMO

We report a case of Bentall and redo-Konno operation. A 39-year-old male with surgical history of Konno operation presented with hemolytic anemia and heart failure. Further evaluations revealed aortic paraprosthetic leak with moderate regurgitation, moderate biventricular outflow tract obstruction, and aortic root aneurysm. During the operation, the old Konno septoplasty patch with organized thrombus and the severely calcified right ventricular patch were replaced, and the aortic root was replaced with a larger mechanical valve in a Valsalva graft. Postoperative images showed appropriately reconstructed biventricular outflow tracts. The Bentall operation with redo-Konno was an excellent option in this situation.

RESUMO

As our population ages, the demand for surgical services in older people is increasing exponentially. Shown to be indispensable in the care of medical patients, use of the comprehensive geriatric assessment (CGA) is also growing in the perioperative setting. We present the case of a previously independent 82-year-old man who underwent a standard preoperative assessment and surgical aortic valve replacement. In the 7 months that followed, prior to his death, he suffered a rapid functional decline contributed to by slow postoperative recovery, delirium and recurrent falls. Post-mortem revealed cardiac amyloid deposition and extensive small vessel disease in the brain. This case highlights the importance of the CGA in the perioperative management of older patients, especially in identification and optimisation of geriatric syndromes and consideration of less-invasive alternative treatments. We review the existing literature on CGA use in cardiothoracic and vascular surgical settings, drawing on experiences learnt from the above case.

RESUMO

This paper proposes an automatic method for classifying Aortic valvular stenosis (AS) using ECG (Electrocardiogram) images by the deep learning whose training ECG images are annotated by the diagnoses given by the medical doctor who observes the echocardiograms. Besides, it explores the relationship between the trained deep learning network and its determinations, using the Grad-CAM.In this study, one-beat ECG images for 12-leads and 4-leads are generated from ECG's and train CNN's (Convolutional neural network). By applying the Grad-CAM to the trained CNN's, feature areas are detected in the early time range of the one-beat ECG image. Also, by limiting the time range of the ECG image to that of the feature area, the CNN for the 4-lead achieves the best classification performance, which is close to expert medical doctors' diagnoses.Clinical Relevance-This paper achieves as high AS classification performance as medical doctors' diagnoses based on echocardiograms by proposing an automatic method for detecting AS only using ECG.

RESUMO

This paper reports our study on the impact of transcatheter aortic valve replacement (TAVR) on the classification of aortic stenosis (AS) patients using cardio-mechanical modalities. Machine learning algorithms such as decision tree, random forest, and neural network were applied to conduct two tasks. Firstly, the pre- and post-TAVR data are evaluated with the classifiers trained in the literature. Secondly, new classifiers are trained to classify between pre- and post-TAVR data. Using analysis of variance, the features that are significantly different between pre- and post-TAVR patients are selected and compared to the features used in the pre-trained classifiers. The results suggest that pre-TAVR subjects could be classified as AS patients but post-TAVR could not be classified as healthy subjects. The features which differentiate pre- and post-TAVR patients reveal different distributions compared to the features that classify AS patients and healthy subjects. These results could guide future work in the classification of AS as well as the evaluation of the recovery status of patients after TAVR treatment.

RESUMO

In a clinical decision support system, the purpose of case-based reasoning is to help clinicians make convenient decisions for diagnoses or interventional gestures. Past experience, which is represented by a case-base of previous patients, is exploited to solve similar current problems using four steps-retrieve, reuse, revise, and retain. The proposed case-based reasoning has been focused on transcatheter aortic valve implantation to respond to clinical issues pertaining vascular access and prosthesis choices. The computation of a relevant similarity measure is an essential processing step employed to obtain a set of retrieved cases from a case-base. A hierarchical similarity measure that is based on a clinical decision tree is proposed to better integrate the clinical knowledge, especially in terms of case representation, case selection and attributes weighting. A case-base of 138 patients is used to evaluate the case-based reasoning performance, and retrieve- and reuse-based criteria have been considered. The sensitivity for the vascular access and the prosthesis choice is found to 0.88 and 0.94, respectively, with the use of the hierarchical similarity measure as opposed to 0.53 and 0.79 for the standard similarity measure. Ninety percent of the suggested solutions are correctly classified for the proposed metric when four cases are retrieved. Using a dedicated similarity measure, with relevant and weighted attributes selected through a clinical decision tree, the set of retrieved cases, and consequently, the decision suggested by the case-based reasoning are substantially improved over state-of-the-art similarity measures.

RESUMO

RESUMEN Introducción: El síndrome de Heyde es la asociación entre estenosis valvular aórtica y sangrado gastrointestinal, por angiodisplasia intestinal. La base fisiopatológica de ese síndrome parece ser una deficiencia adquirida del factor de Von Willebrand, que lleva al sangrado de malformaciones arteriovenosas angiodisplásicas. Las alternativas de tratamiento incluyen la localización de puntos de sangrado y la cauterización, pero tal opción terapéutica está asociada a alta recurrencia. El reemplazo de la válvula parece ofrecer la mejor esperanza de resolución a largo plazo del sangrado y debe ser considerada en la mayoría de las veces. Objetivos: Presentar el caso de un síndrome de Heyde, una causa infrecuente de hemorragia digestiva. Caso clínico: Paciente de 74 años con antecedentes estenosis aórtica y sangrado gastrointestinal debido a angiodisplasia duodenal localizada en la segunda porción de esta, tratada mediante la escleroterapia. Conclusiones: El síndrome de Heyde es una asociación poco frecuente entre una valvulopatía aortica y sangrado digestivo por una angiodisplasia que puede presentarse en cualquier parte del tubo digestivo(AU)


ABSTRACT Introduction: Heyde syndrome is the association between aortic valve stenosis and gastrointestinal bleeding, due to intestinal angiodysplasia. The pathophysiological basis of this syndrome seems to be acquired Von Willebrand factor deficiency, which leads to bleeding from angiodysplastic arteriovenous malformations. Management alternatives include localization of bleeding points and cauterization, but such a therapeutic option is associated with high recurrence. Valve replacement seems to offer the best hope for long-term solving of bleeding and should be considered for most of the cases. Objectives: To present a case of Heyde syndrome, a rare cause of gastrointestinal bleeding. Clinical case: A 74-year-old patient is presented with a history of aortic stenosis and gastrointestinal bleeding due to duodenal angiodysplasia located in the second portion of it, managed by sclerotherapy. Conclusions: Heyde syndrome is a rare association between aortic valve disease and digestive bleeding due to angiodysplasia that can occur in any part of the digestive tract(AU)

RESUMO

BACKGROUND: Limited data suggest that transcatheter (TAVR) as compared with surgical aortic valve replacement (SAVR) may be more effective in female than male patients. To date, most evidence is derived from subgroup analyses of large trials, and a dedicated randomized trial evaluating whether there is a difference in outcomes between these interventions in women is warranted. The RHEIA trial will compare the safety and efficacy of TAVR with SAVR in women with severe symptomatic aortic stenosis requiring aortic valve intervention, irrespective of surgical risk. METHODS/DESIGN: The RHEIA trial is a prospective, randomized, controlled study that will enroll up to 440 patients across 35 sites in Europe. Women with severe symptomatic aortic stenosis, with any but prohibitive surgical risk status, will be randomized 1:1 to undergo aortic valve intervention with either transfemoral TAVR with the SAPIEN 3 or SAPIEN 3 Ultra device or SAVR and followed up for 1 year. The objective is to determine whether TAVR is non-inferior to SAVR in this patient population and, if this is fulfilled whether TAVR is actually superior to SAVR. The primary safety/efficacy endpoint is a composite of all-cause mortality, all stroke, and re-hospitalization (for valve or procedure-related symptoms or worsening congestive heart failure) at 1 year post-procedure. Other outcomes (assessed at 30 days and/or 1 year) include all-cause mortality; bleeding, vascular, cardiac, cerebrovascular and renal complications; aortic valve prosthesis and left ventricular function; cognitive function, health status, and quality of life. DISCUSSION: The RHEIA study has been designed to evaluate the safety and efficacy of TAVR compared with SAVR specifically in women with severe symptomatic aortic stenosis, irrespective of the level of surgical risk. The results will be the first to provide specific randomized evidence to guide treatment selection in female patients with severe symptomatic aortic stenosis.

RESUMO

To compare outcomes of ultrasound guidance (USG) versus fluoroscopy roadmap guidance (FG) angiography for femoral artery access in patients who underwent transfemoral (TF) transcatheter aortic valve implantation (TAVI) to determine whether routine USG use was associated with fewer vascular complications. Vascular complications are the most frequent procedural adverse events associated with TAVI. USG may provide a decreased rate of access site complications during vascular access compared with FG. Patients who underwent TF TAVI between July 2012 and July 2017 were reviewed and outcomes were compared. Vascular complications were categorized by Valve Academic Research Consortium-2 criteria and analyzed by a multivariable logistic regression adjusting for potential confounding risk factors including age, gender, body mass index, peripheral vascular disease, Society of Thoracic Surgeons score and sheath to femoral artery ratio. Of the 612 TAVI patients treated, 380 (63.1%) were performed using USG for access. Routine use of USG began in March 2015 and increased over time. Vascular complications occurred in 63 (10.3%) patients and decreased from 20% to 3.9% during the study period. There were fewer vascular complications with USG versus FG (7.9% vs 14.2%, p = 0.014). After adjusting for potential confounding risk factors that included newer valve systems, smaller sheath sizes and lower risk patients, there was still a 49% reduction in vascular complications with USG (odds ratio 0.51, 95% confidence interval 0.29 to 0.88, p = 0.02). In conclusion, USG for TF TAVI was associated with reduced vascular access site complications compared with FG access even after accounting for potential confounding risk factors and should be considered for routine use for TF TAVI.

RESUMO

AIMS: Data regarding outcomes for patients with severe aortic stenosis (AS) with concomitant aortic insufficiency (AI), undergoing transcatheter aortic valve replacement (TAVR) are limited. This study aimed to analyze the prevalence of severe AS with concomitant AI among patients undergoing TAVR and outcomes of TAVR in this patient group. METHODS AND RESULTS: Using data from the STS/ACC-TVT Registry, we identified patients with severe AS with or without concomitant AI who underwent TAVR between 2011 and 2016. Patients were categorized based on the severity of pre-procedural AI. Multivariable proportional hazards regression models were used to examine all-cause mortality and heart failure (HF) hospitalization at 1-year. Among 54,535 patients undergoing TAVR, 42,568 (78.1%) had severe AS with concomitant AI. Device success was lower in patients with severe AS with concomitant AI as compared with isolated AS. The presence of baseline AI was associated with lower 1 year mortality (HR 0.94 per 1 grade increase in AI severity; 95% CI, 0.91-0.98, P < .001) and HF hospitalization (HR 0.87 per 1 grade increase in AI severity; 95% CI, 0.84-0.91, P < .001). CONCLUSIONS: Severe AS with concomitant AI is common among patients undergoing TAVR, and is associated with lower 1 year mortality and HF hospitalization. Future studies are warranted to better understand the mechanisms underlying this benefit. SHORT ABSTRACT: In this nationally representative analysis from the United States, 78.1% of patients undergoing TAVR had severe AS with concomitant AI. Device success was lower in patients with severe AS with concomitant AI as compared with isolated AS. The presence of baseline AI was associated with lower 1 year mortality (HR 0.94 per 1 grade increase in AI severity; 95% CI, 0.91-0.98, P < .001) and HF hospitalization (HR 0.87 per 1 grade increase in AI severity; 95% CI, 0.84-0.91, P < .001).

RESUMO

Previous studies indicate that women who underwentwho underwent transcatheter aortic valve implantation (TAVI) have poorer 30-day outcomes compared with men. However, the effect of gender as a prognostic factor for long-term outcomes following TAVI remains unclear. Between 2008 and 2018, all patients (n = 683) who underwent TAVI in 2 centres in Melbourne, Australia were prospectively included in a registry. The primary end-point was long-term mortality. The secondary end points were Valve Academic Research Consortium-2 (VARC-2) in-hospital complications and mortality at 30-days and 1-year. Of 683 patients, 328 (48%) were women. Women had a higher mean STS-PROM score (5.2 ± 3.1 vs 4.6 ± 3.5, p < 0.001) but less co-morbidities than men. Women had a significantly higher in-hospital bleeding rates (3.3% vs 1.0%, Odds Ratio 4.21, 95% confidence interval [CI] 1.16 to15.25, p = 0.027) and higher 30-day mortality (2.4% vs 0.3%, hazard ratio [HR] 8.75, 95% CI 1.09 to 69.6, p = 0.040) than men. Other VARC-2 outcomes were similar between genders. Overall mortality rate was 36% (246) over a median follow up of 2.7 (interquartile rang [IQR] 1.7 to 4.2) years. Median time to death was 5.3 (95% CI 4.7 to 5.7) years. One-year mortality was similar between genders (8.3% vs 7.8%), as was long-term mortality (HR = 0.91, 95% CI 0.71 to 1.17, p = 0.38). On multivariable analysis, female gender was an independent predictor for 1-year mortality (HR = 2.33, 95% CI 1.11 to 4.92, p = 0.026), but not long-term mortality (HR = 0.78, 95% CI 0.54 to 1.14, p = 0.20). In the women only cohort, STS-PROM was the only independent predictor of long-term mortality (HR 1.88, 95% CI 1.42 to 2.48, p < 0.001). In conclusion, women had higher rates of peri-procedural major bleeding and 30-day mortality following TAVI. However, long-term outcomes were similar between genders.

RESUMO

Aortic valve disease (AVD) has similarities to atherosclerosis in the case of aortic stenosis. The important role of platelet in the pathogenesis of atherosclerosis is known. The goal of this study is to evaluate whether platelet disorders play any role in aortic valve disease. We used patients with idiopathic thrombocytopenic purpura (ITP) for this study. We evaluated any association between ITP and AVD using a large inpatient database. The International Classification of Diseases, Ninth Revision, and Clinical Modification (ICD-9-CM) codes for ITP and AVD from the Nationwide Inpatient Sample (NIS) database were used for this study. Uni- and multivariate analyses were performed on data from 2002 to 2011 to evaluate any association between ITP and AVD. In the 2002 database, AVD was present in 1.73% of ITP patients versus 1.12% in the control population (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.34-1.81; p < 0.001). In the 2011 database, AVD was present in 1.96% of ITP patients versus 1.33% in the control population (OR, 1.48; 95% CI, 1.30-1.68; p < 0.001). ITP remained independently associated with AVD following a multivariate logistic regression analysis adjusting for age, gender, diabetes mellitus, hypertension, and hyperlipidemia in 2002 (OR, 1.35; 95% CI, 1.16-1.57; p < 0.001) with a trend of this association in 2011 (OR, 1.12; 95% CI, 0.98-1.27; p = 0.096). ITP was strongly associated with AVD over the 10-year period analyzed in a large inpatient database. The reason for this association is not known warranting further investigations.

RESUMO

Bicuspid aortic valve (BAV) is the most common congenital cardiac abnormality in adults, and symptoms typically develops in adulthood. In the majority of cases, BAV disease progresses with age and surgical aortic valve replacement (AVR) is performed with excellent operative outcomes. Based on a series of randomized trials, transcatheter AVR (TAVR) has evolved from a novel technology to an established therapy for patients with symptomatic severe aortic stenosis (AS) regardless of risk profile. Despite exclusion of bicuspid anatomy from the randomized trials, an increasing number of patients with BAV-AS have been treated with TAVR. Recent observational studies showed the comparable outcomes of TAVR between bicuspid and tricuspid AS. However, worse outcomes in patients with unfavorable bicuspid anatomy such as calcified raphe plus excessive leaflet calcification have raised concerns for TAVR in younger and lower risk population. For the further expansion of TAVR toward BAV-AS population, we need randomized trials of TAVR in this population. Until then, previous registry data combined with computed tomographic-based anatomical assessment may guide the optimal therapy in patients with bicuspid anatomy.

RESUMO

INTRODUCCIÓN Y OBJETIVOS: La estenosis aórtica degenerativa es la valvulopatía más frecuente. Aún no está claro cómo identificar a los pacientes asintomáticos con fracción de eyección del ventrículo izquierdo normal y alta probabilidad de eventos que por ello pudieran beneficiarse de una intervención valvular precoz. En este estudio se describe un protocolo de hemodinámica de esfuerzo para los pacientes asintomáticos con estenosis aórtica moderada o grave para evaluar su valor pronóstico para esta población. MÉTODOS: Estudio prospectivo unicéntrico de una población de pacientes con estenosis aórtica moderada o grave asintomáticos. Los pacientes realizaron una ergoespirometría para confirmar la ausencia de síntomas en esfuerzo. Después los pacientes se sometieron a un cateterismo cardiaco derecho basal y de esfuerzo. Se definió evento como muerte o necesidad de reemplazo de válvula aórtica quirúrgico o percutáneo basado en las guías clínicas. RESULTADOS: Se sometió a 33 pacientes a cateterismo cardiaco derecho basal y de esfuerzo. El área valvular aórtica media fue de 1,08 cm2 y el gradiente aórtico medio, 39 mmHg. La presión arterial pulmonar media fue de 21 mmHg, con una presión de oclusión en la arteria pulmonar de 14 mmHg y un gasto cardiaco de 5,6 l/min. La presión pulmonar media en ejercicio máximo fue de 34 mmHg. Tras un seguimiento medio de 27 meses, 8 pacientes sufrieron un evento (24%). No hubo diferencias en las variables basales, el área valvular aórtica o los parámetros de ergoespirometría. Los pacientes con evento no tuvieron mayores presiones pulmonares o presiones de llenado en ejercicio máximo, pero el grupo con eventos mostró menor saturación de oxígeno en la arteria pulmonar en esfuerzo (mediana, el 48 frente al 57%; p = 0,03). CONCLUSIONES: El cateterismo cardiaco de esfuerzo es seguro y factible en esta población. La saturación de oxígeno en la arteria pulmonar en esfuerzo podría identificar a un grupo de pacientes con un aumento del riesgo de eventos adversos graves


INTRODUCTION AND OBJECTIVES: Degenerative aortic stenosis (DAS) is the most frequent valvular heart disease. It remains unclear how to identify asymptomatic DAS patients with normal left ventricular ejection fraction who have a high probability of event occurrence and would thus benefit from early intervention. Here, we describe a protocol for exercise hemodynamics in true asymptomatic patients with moderate or severe DAS and assess the prognostic value of the data obtained in this population. METHODS: This study involved a prospective single-centre registry of consecutive asymptomatic patients with moderate or severe DAS. Patients underwent cardiopulmonary exercise testing to confirm symptom absence during exercise and then right heart catheterization (RHC) at rest and during exercise. Events were defined as death, surgical aortic valve replacement, or transcatheter aortic valve implantation according to clinical guidelines. RESULTS: Thirty-three patients underwent baseline and exercise RHC. The mean aortic valve area was 1.08 cm2 and the aortic gradient was 39mmHg. The mean pulmonary artery pressure was 21mmHg with a pulmonary artery occlusion pressure of 14mmHg and cardiac output of 5.6 L/min. The mean pulmonary artery pressure at peak exercise was 34mmHg. After a mean follow-up of 27 months, 8 patients experienced an event (24%). There were no differences in baseline variables, aortic valve area, or cardiopulmonary exercise testing parameters between the event and event-free groups. Patients with an event did not have higher pulmonary or filling pressures after peak exercise but had lower pulmonary artery oxygen saturation on effort (median, 48% vs 57%, P=.03). Exercise RHC is feasible and safe in this population. Peak pulmonary artery oxygen saturation might identify patients with increased risk of serious adverse events

RESUMO

Right anterior minithoracotomy is gaining larger acceptance for isolated aortic valve replacement. In some patients, however, surgical exposure during the intervention may be challenging even for experienced surgeons or centers. In our opinion, proper preoperative selection of the patients by computed tomography scan seems mandatory. We routinely perform right anterior minithoracotomy, and over time, we have found that the angle between the right border of the sternum and the left side of the aorta, at the level of the pulmonary artery, helps with patient selection.

RESUMO

BACKGROUND: Patients with bicuspid aortic valve stenosis (BAV) were excluded from all the trileaflet aortic valve stenosis (TAV) pivotal trials, and therefore, their outcomes are not clearly defined. The aim of the study was to evaluate the outcomes of transcatheter aortic valve replacement (TAVR) in patients with BAV and compared them with those of TAV. METHODS: We evaluated the outcomes following TAVR of patients with BAV at our institution between April 2011 and November 2016 and compared them with the outcomes of patients with TAV treated with TAVR. The χ2 and the Mann-Whitney U tests were used to compare the groups, and a Kaplan-Meier analysis was performed to estimate long-term survival. RESULTS: TAVR was performed in a total of 567 patients, from which 50 (8.8%) had BAV and 517 (91.2%) had TAV. Patients with BAV were younger and had higher prevalence of chronic obstructive pulmonary disease, lower prevalence of coronary artery disease, higher body mass index, and lower Society of Thoracic Surgeons score (STS PROM). Patients with BAV had a slightly higher mean aortic valve gradient postoperatively (median 12 mm Hg [10-15] vs 10 [7-13], P < .001), but paravalvular aortic regurgitation was not different between the groups (> mild 4.0% vs 3.5%, P = .541). Clinical outcomes were not different between the groups, including stroke (2.0% vs 1.5, P = .567) and the 30-day all-cause mortality (6.0% vs 1.5, P = .064). The 2-year survival (82.0% vs 83.4, P = .476) was similar between the groups. CONCLUSIONS: This initial experience suggests that TAVR can be safely performed in patients with BAV, achieving similar short-term procedural and clinical outcomes when compared with patients with TAV.

RESUMO

BACKGROUND: Aortic stenosis (AS) is a common cardiac condition whose prevalence increases with age. The symptom burden associated with severe aortic stenosis (AS) can introduce significant lifestyle disruptions and if left untreated can lead to a poor prognosis. Quality of life (QoL) is an important consideration in these patients. The TASQ is a QoL tool that was developed for aortic stenosis patients. We evaluated the psychometric properties of this specific questionnaire in patients who underwent transcatheter aortic valve implantation (TAVI), which is a therapeutic option for patients with severe aortic stenosis (AS). METHODS: The properties of the TASQ in measuring QoL were evaluated in AS patients undergoing TAVI. Patients presenting for the TAVI procedure (N = 62) were evaluated pre-TAVI, at discharge, 1-month, and 3-month follow-ups. Demographic information as well as caregiver status, and daily activities were recorded. In addition to the TASQ, they completed the KCCQ (Kansas City Cardiomyopathy Questionnaire) and the IIRS (Illness Intrusiveness Rating Scale). RESULTS: The TASQ is a 16-item self-administered questionnaire that assesses AS-specific QoL across five domains: physical symptoms; physical limitations; emotional impact; social limitations, and health expectations. TASQ subscales are internally consistent (α = 0.74-0.96) and showed significant improvements from baseline across assessments (p < 0.001). Construct validity evidence was demonstrated by correlations consistent with theoretically derived hypotheses across time points. CONCLUSIONS: The TASQ is a brief measure of AS-specific QoL that is sensitive to change in patients undergoing TAVI. Items on the TASQ capture important QoL concerns reported by AS patients, suggesting this is a measure of relevant and meaningful outcomes for this patient population. Detection of early improvements in QoL by the TASQ is promising, with important implications for the evaluation of procedural outcomes in this population.
