Abstract Background: Frailty is a geriatric syndrome that diminishes potential functional recovery after any surgical procedure. Preoperative surgical risk assessment is crucial to calibrate the risk and benefit of cardiac surgery. The aim of this study was to test usefulness of FRAIL Scale and other surgical-risk-scales and individual features of frailty in cardiac aortic valve surgery. Methods: Prospective study. From May-2014 to February-2016, we collected 200 patients who underwent aortic valve replacement, either surgically or transcatheter. At 1-year follow-up, quality of life measurements were recorded using the EQ-5D (EuroQol). Univariate and multivariate analyses correlated preoperative condition, features of frailty and predicted risk scores with mortality, morbidity and quality of life at 1 year of follow-up. Results: Mean age 78.2y, 56%male. Mean-preoperative-scores: FRAIL scale 1.5(SD 1.02), STS 2.9(SD 1.13), BI 93.8(SD 7.3), ESlog I 12.8(SD 8.5) and GS 7.3s (SD 1.9). Morbidity at discharge, 6 m and 1 year was 51%, 14% and 28%. Mortality 4%. Survival at 6m/ 1-y was 97% / 88%. Complication-rate was higher in TAVI group due to-vascular complications. Renal dysfunction, anemia, social dependence and GS slower than 7 seconds were associated with morbidity. On multivariate analysis adjusted STS, BI and GS speed were statistically significant. Quality of life at 1-year follow-up adjusted for age and prosthesis type showed a significant association with STS and FRAIL scale scores. Conclusions: Frailty increases surgical risk and is associated with higher morbidity. Preoperative GS slower 7 s, and STS and FRAIL scale scores seem to be reliable predictors of quality of life at 1-year follow-up.

Abstract Background Infective endocarditis (IE) may be complicated by acute kidney injury, yet data on the use of dialysis and subsequent reversibility are sparse. Methods Using Danish nationwide registries, we identified patients with first-time IE from 2000 to 2017. Dialysis naïve patients were grouped into: those with and those without dialysis during admission with IE. Continuation of dialysis was followed one year post-discharge. Multivariable adjusted Cox proportional hazard analysis was used to examine one-year mortality for patients surviving IE according to use of dialysis. Results We included 7,307 patients with IE; 416 patients (5.7%) initiated dialysis treatment during admission with IE and these were younger, had more comorbidities and more often underwent cardiac valve surgery compared with non-dialysis patients (47.4% vs. 20.9%). In patients with both cardiac valve surgery and dialysis treatment (n=197), 153 (77.7%) initiated dialysis on- or after the date of surgery. The in-hospital mortality was 40.4% and 19.0% for patients with and without dialysis, respectively (p<0.0001). Of those who started dialysis and survived hospitalization, 21.6% continued dialysis treatment within one year after discharge. In multivariable adjusted analysis, dialysis during admission with IE was associated with an increased one-year mortality from IE discharge, HR=1.64 (95% CI: 1.21-2.23). Conclusion In dialysis-naïve patients with IE, approximately 1 in 20 patients initiated dialysis treatment during admission with IE. Dialysis identified a high-risk group with an in-hospital mortality of 40% and an approximately 20% risk of continued dialysis. Those with dialysis during admission with IE showed worse long-term outcomes than those without.

(1) Background: Sepsis-associated acute kidney injury (AKI) can lead to permanent kidney damage, although the long-term prognosis in patients with septic shock remains unclear. This study aimed to identify risk factors for the development of chronic kidney disease (CKD) in septic shock patients with AKI. (2) Methods: A single-site, retrospective cohort study was conducted using a registry of adult septic shock patients. Data from patients who had developed AKI between January 2011 and April 2017 were extracted, and 1-year follow-up data were analysed to identify patients who developed CKD. (3) Results: Among 2208 patients with septic shock, 839 (38%) had AKI on admission (stage 1: 163 (19%), stage 2: 339 (40%), stage 3: 337 (40%)). After one year, kidney function had recovered in 27% of patients, and 6% had progressed to CKD. In patients with stage 1 AKI, 10% developed CKD, and mortality was 13% at one year; in patients with stage 2 and 3 AKI, the CKD rate was 6%, and the mortality rate was 42% and 47%, respectively. Old age, female, diabetes, low haemoglobin levels and a high creatinine level at discharge were seen to be risk factors for the development of CKD. (4) Conclusions: AKI severity correlated with mortality, but it did not correlate with the development of CKD, and patients progressed to CKD, even when initial AKI stage was not severe. Physicians should focus on the recovery of renal function, and ensure the careful follow-up of patients with risk factors for the development of CKD.

AbstractTo compare the ability of cardiac magnetic resonance tomography (CMR) and transthoracic echocardiography (TTE) to predict the need for valve surgery in patients with chronic aortic regurgitation on a mid-term basis. 66 individuals underwent assessment of aortic regurgitation (AR) both in CMR and TTE between August 2012 and April 2017. The follow-up rate was 76% with a median of 5.1 years. Cox proportional hazards method was used to assess the association of the time-to-aortic-valve-surgery, including valve replacement and reconstruction, and imaging parameters. A direct comparison of most predictive CMR and echocardiographic parameters was performed by using nested-factor-models. Sixteen patients (32%) were treated with aortic valve surgery during follow-up. Aortic valve insufficiency parameters, both of echocardiography and CMR, showed good discriminative and predictive power regarding the need of valve surgery. Within all examined parameters AR gradation derived by CMR correlated best with outcome [χ2 = 27.1; HR 12.2 (95% CI: 4.56, 36.8); (p < 0.0001)]. In direct comparison of both modalities, CMR assessment provided additive prognostic power beyond echocardiographic assessment of AR but not vice versa (improvement of χ2 from 21.4 to 28.4; p = 0.008). Nested model analysis demonstrated an overall better correlation with outcome by using both modalities compared with using echo alone with the best improvement in the moderate to severe AR range with an echo grade II out of III and a regurgitation fraction of 32% in CMR. This study corroborates the capability of CMR in direct quantification of AR and its role for guiding further treatment decisions particularly in patients with moderate AR in echocardiography.

Purpose Haemorrhage, preeclampsia and sepsis are the leading causes renal dysfunction in women with a maternal nearmiss(MNM) complication. The study aimed to assess the prevalence, pattern and follow up of these women. Methods This was a hospital based prospective observational study, conducted over one year. All women with a MNM leading to acute kidney injury (AKI) were analysed for fetomaternal outcomes and renal function at 1 year of followup. Results Incidence of MNM was 43.04 per 1000 livebirths. 18.2% women developed AKI. 51.1% women developed AKI in the puerperal period. Most common cause of AKI was haemorrhage seen in 38.3% women. Majority of women had s.creatinine between 2.1 to 5 mg/dl and 44.68% required dialysis. 80.8% women recovered fully when the treatment was initiated within 24 h. One patient underwent renal transplant. Conclusion Early diagnosis and treatment of AKI results in full recovery.

Abstract Background Acute kidney injury (AKI) complicating transcatheter aortic valve implantation (TAVI) is relatively frequent and associated with significant morbidity. Previous studies have shown a higher 30-day and 1-year mortality risk in patients with periprocedural AKI. Our aim was to identify the prognostic impact of periprocedural AKI on long-term follow-up. Methods This is a single-center prospective study evaluating patients undergoing TAVI for severe aortic stenosis. AKI was defined according to the Valve Academic Research Consortium 2 definition, as an absolute increase in serum creatinine ≥0.3 mg/dL or an increase &gt;50% within the first week following TAVI. Mortality data were compared between patients who developed AKI and those who did not. Logistic and Cox regressions were used for survival analysis. Results The final analysis included 1086 consecutive TAVI patients. AKI occurred in 201 patients (18.5%). During the follow-up period, 289 patients died. AKI was associated with an increased risk of 30-day mortality {4.5 versus 1.9% in the non-AKI group; hazard ratio [HR] 3.70 [95% confidence interval (CI) 1.35–10.13]}. Although 1-year mortality was higher in the AKI group in univariate analysis, it was not significant after a multivariate regression. AKI was a strong predictor of longer-term mortality [42.3 versus 22.7% for 7-year mortality; HR 1.71 (95% CI 1.30–2.25)]. In 189 of 201 patients we had data regarding recovery from AKI up to 30 days after discharge. In patients with recovery from AKI, the mortality rate was lower (38.2 versus 56.6% in the nonrecovery group; P = 0.022). Conclusions Periprocedural AKI following TAVI is a strong risk factor for short-term as well as long-term mortality (up to 7 years). Therefore more effort is needed to reduce this complication.
