Experiencia inicial con la prótesis de despliegue rápido en posición aórtica Edwards Intuity

ResumenObjetivoDisponemos de una nueva clase de prótesis aórticas de despliegue rápido para tratamiento quirúrgico de la estenosis aórtica. Permitirían disminuir los tiempos quirúrgicos y facilitarían la cirugía mínimamente invasiva. Presentamos nuestra experiencia inicial con la válvula Edwards Intuity en el contexto del estudio multicéntrico Foundation.Pacientes y métodosEntre septiembre de 2012 y febrero de 2014 se implantaron 25 prótesis aórticas Edwards Intuity en 26 pacientes (77±4,3años; 52% varones). Veinticuatro (96%) fueron reemplazo valvular aislado, y 9 pacientes (36%) tuvieron abordaje mínimamente invasivo. Los pacientes fueron estudiados al alta, a los 3meses y al año de la intervención.ResultadosHubo éxito en el implante en el 96,2% de los pacientes (25/26). No hubo mortalidad hospitalaria. Seguimiento medio de 11±5,4meses, supervivencia acumulada del 96%. Un paciente falleció a los 11meses por un ictus isquémico. El tiempo medio de pinzamiento aórtico fue de 38,2±10,1min y el tiempo medio de circulación extracorpórea, de 62,4±11,1min. A los 3meses, el área valvular efectiva media fue de 1,70±0,42cm2. El 91% de los pacientes (23/25) estaban en grado funcionali en el seguimiento.ConclusionesEl implante de la válvula Edwards Intuity para el tratamiento de la estenosis aórtica ha sido factible, seguro y eficaz. Los tiempos de isquemia miocárdica y de circulación extracorpórea parecen reducirse en comparación con la cirugía valvular aórtica habitual. El comportamiento hemodinámico inicial de la prótesis Edwards Intuity es excelente.AbstractObjectiveA new class of rapid deployment prostheses is now available for surgical treatment of aortic stenosis. These prostheses offer the possibility of reducing the duration of cardiopulmonary bypass and aortic clamping times, and facilitate the use of minimally invasive surgery. We present our initial experience with the Edwards Intuity valve in the context of a multicentre Foundation study.Patients and methodsBetween September 2012 and February 2014, 25 Edwards Intuity valves were implanted in 26 patients (77±4.3years; 52% male). Twenty-four (96%) were isolated aortic valve replacement; a minimally invasive approach was used on 9 patients (36%). Patients were studied at discharge, three months, and one year after surgery.ResultsImplantation success rate was 96.2% (25/26). There was no hospital mortality. Mean follow-up of 11±5.54months, cumulative survival of 96%. One patient died eleven months after surgery due to ischaemic stroke. The mean aortic clamping time was 38.2±10.1minutes, and the mean cardiopulmonary bypass (CPB) time was 62.4±11.1minutes. In the echocardiography at 3months, the mean effective valve area was 1.70±0.42cm2, and 91% of patients (23/25) were in functional classi NYHA at follow-up.ConclusionsThe implantation of the Edwards Intuity valve for surgical treatment of aortic stenosis has shown to be feasible, safe and effective. Times of myocardial ischaemia and extracorporeal circulation appear to be reduced compared with normal aortic valve surgery. The initial haemodynamic performance of the Edwards Intuity prosthesis is excellent

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Three-Dimensional Morphology of the Left Ventricular Outflow Tract: Impact on Grading Aortic Stenosis Severity.

BACKGROUND: Left ventricular outflow tract (LVOT) measurement is a critical step in the quantification of aortic valve area. The assumption of a circular morphology of the LVOT may induce some errors. The aim of this study was to assess the three-dimensional (3D) morphology of the LVOT and its impact on grading aortic stenosis severity. METHODS: Fifty-eight patients with aortic stenosis were studied retrospectively. LVOT dimensions were measured using 3D transesophageal echocardiography at three levels: at the hinge points (HP) of the aortic valve and at 4 and 8 mm proximal to the annular plane. Results were compared with standard two-dimensional echocardiographic measurements. RESULTS: Three-dimensional transesophageal echocardiography showed a funnel shape that was more circular at the HP and more elliptical at 4 and 8 mm proximal to the annular plane (circularity index = 0.92 vs 0.83 vs 0.76, P < .001). Cross-sectional area was smaller at the HP and larger at 4 and 8 mm from the annular plane (3.6 vs 3.9 vs 4.1 cm2, P = .001). The best correlation between two-dimensional and 3D transesophageal echocardiographic dimensions was at the HP (intraclass correlation coefficient = 0.75; 95% CI, 0.59-0.86). When the HP approach was selected, there was a reduction in the percentage of patients with low flow (from 41% to 29%). CONCLUSIONS: A large portion of patients with aortic stenosis have funnel-shaped and elliptical LVOTs, a morphology that is more pronounced in the region farther from the annular plane. Two-dimensional LVOT measurement closer to the annular plane has the best correlation with 3D measurements. Measurement of the LVOT closer to the annular plane should be encouraged to reduce measurement errors

Validity and reliability of the measurement instrument of the nursing outcome health-related Physical Fitness (2004), proposed and transculturally adapted to the Spanish context

Abstract Background Presently, physical inactivity is the main public health problem in many countries worldwide. Physical activity promotes the maintenance or improvement of one’s physical condition. Physical fitness has been established as the main biological marker of the state of health of an individual, and therefore, there is a clear need to measure health-related physical fitness through the use of a reliable and valid instrument. This study is a continuation of the transcultural adaptation process and a new proposal of the nursing outcome Physical Fitness (2004), found in the 5th Edition of the Nursing Outcomes Classification. The objective of this study was to examine the validity and reliability of the nursing outcome Health-Related Physical Fitness survey, proposed and transculturally adapted to the Spanish context. Methods An instrumental study to validate the nursing outcome Physical Fitness (2004), from the 5th Edition of the Nursing Outcome Classification was carried out. It took place between the months of May, 2016 to May, 2017. On the first stage, the instrument proposed Health-Related Physical Fitness survey was administered to 160 adults who used the Health Services of Murcia, Spain by three independent evaluators. After 4 weeks, it was administered again to 33 participants to calculate the intra-rater reliability. Lastly, the SF-12v2 Health Survey was administered to obtain external evidence of validity. Results The inter-rater reliability of the nursing outcome proposed obtained high values (between 0.91–0.99) in the evaluations performed by the three evaluators. As for the intra-rater reliability, high values were obtained (0.94–1), except for the item “balance”, which was moderate (0.56). Lastly, a positive and statistically significant correlation (p < 0.05) was obtained between the Physical Component Summary, and the dimensions Physical Functioning and General Health from the SF-12v2 Health Survey, and the global score of the Health-Related Physical Fitness proposed instrument. Conclusions The validity and reliability results of the nursing outcome Health-Related Physical Fitness survey, proposed and transculturally adapted to the Spanish context, were adequate for its use by nurses with adults who use the Health Services of Murcia. However, this instrument must be analyzed with more diverse samples of health services users

Rotura de balón y extravasación de alcohol hacia la arteria descendente anterior durante la ablación septal en paciente con miocardiopatía hipertrófica obstructiva

Presentamos un caso de rotura del balón de oclusión septal durante el procedimiento de ablación con alcohol en un paciente con miocardiopatía hipertrófica obstructiva. La rotura causó reflujo de alcohol a la arteria descendente anterior y originó angina, leve hipocinesia global, transitoria de ventrículo izquierdo y bloqueo auriculoventricular avanzado. La función contráctil se recuperó en pocos minutos y el pico de creatincinasa fue de 526 U. A pesar de restaurarse el ritmo sinusal, hubo episodios de bloqueo auriculoventricular que obligaron al implante de marcapasos definitiv
