Show moreBackground Progressive renal insufficiency is frequent in heart failure patients with a left ventricular assist device (LVAD). The optimal strategy for long-term dialysis in LVAD patients and its effect on quality-of-life in these patients remain to be determined.Case summary Our 55-year-old patient with pre-existing renal insufficiency received an LVAD as destination therapy because of advanced ischaemic heart failure. Six years after implantation, he developed end-stage renal disease for which peritoneal dialysis (PD) was initiated. Left ventricular assist device flow alterations during uttrafiltration did not cause clinical or technical problems. The patient's exercise capacity increased and quality-of-life improved. Over 7.5 years after LVAD implantation and 16 months after PD initiation, he died from encephalitis.Discussion Despite initial improvement, renal function often gradually decreases after LVAD implantation. Data on long-term renal replacement therapy in LVAD patients are limited. Haemodialysis is most commonly applied. Conceptually, however, PD has advantages over haemodialysis including less bloodstream infections, less haemodynamic shifts, and the comfort of the ambulant setting. This case illustrates that PD in an LVAD patient is feasible and improves quality-of-life. Key factors contributing to successful PD in LVAD patients may be a good right ventricular function and close cardiology-nephrology collaboration. Show less

Show moreObjectives Our study aimed to evaluate myocardial strain and tissue characteristics by multiparametric cardiovascular magnetic resonance (CMR) imaging in end-stage renal disease (ESRD) patients on peritoneal dialysis with preserved left ventricular ejection fraction (LVEF).Methods ESRD patients on peritoneal dialysis with echocardiographic LVEF > 50% and age- and sex-matched healthy volunteers underwent multiparametric CMR at 3 T. LV function, LV myocardial native T1 and T2, and biventricular strain were measured and compared between the patients and controls. Associations of LV myocardial mass index (LVMI) with tissue characterization and strain were evaluated by multiple linear regression.Results A total of 65 subjects (42 healthy volunteers and 23 ESRD patients) were enrolled. ESRD group demonstrated larger LVMI, higher native T1 and T2 (1301.9 +/- 30.6 ms, 44.6 +/- 2.6 ms) than those of the control group (1255.8 +/- 45.2 ms, 40.5 +/- 1.6 ms; both p < 0.001). Decreased LV strain and increased right ventricular circumferential strain were observed in the ESRD group. In ESRD patients with normal diastolic function on echocardiography, native T1 and T2 values were higher than those of the control group (p = 0.006, p = 0.001). Increased LVMI was associated with increased native T1 (p = 0.001) and T2 value (p < 0.001) after adjusting for age and sex. Increased myocardial native T1 value was associated with reduced LV strain after adjusting age, sex, and LVMI.Conclusions ESRD patients on peritoneal dialysis with preserved LVEF demonstrated higher myocardial mass, higher native T1 and T2 values, decreased LV strain, and increased RVGCS compared with healthy controls. Increased myocardial T1 and T2 were found in ESRD even when no systolic or diastolic dysfunction was detected by routine echocardiography. Show less

Show moreBackground More than 6200 End Stage Renal Disease patients in the Netherlands are dependent on dialysis, either performed at home or in a dialysis centre. Visiting a dialysis centre three times a week is considered a large burden by many patients. However, recent data regarding the effects of dialysis at home on quality of life, clinical outcomes, and costs compared with in-centre haemodialysis are lacking. Methods The Dutch nOcturnal and hoME dialysis Study To Improve Clinical Outcomes (DOMESTICO) is a nationwide, prospective, observational cohort study that will include adult patients starting with a form of dialysis. Health-related quality of life, as the primary outcome, clinical outcomes and costs, as secondary outcomes, will be measured every 3-6 months in patients on home dialysis, and compared with a control group consisting of in-centre haemodialysis patients. During a 3-year period 800 home dialysis patients (600 peritoneal dialysis and 200 home haemodialysis patients) and a comparison group of 800 in-centre haemodialysis patients will be included from 53 Dutch dialysis centres (covering 96% of Dutch centres) and 1 Belgian dialysis centre (covering 4% of Flemish centres). Discussion DOMESTICO will prospectively investigate the effect of home dialysis therapies on health-related quality of life, clinical outcomes and costs, in comparison with in-centre haemodialysis. The findings of this study are expected to ameliorate the shared decision-making process and give more guidance to healthcare professionals, in particular to assess which type of patients may benefit most from home dialysis.
