Project description:BackgroundIn patients with refractory heart failure (HF) peritoneal dialysis (PD) is associated with improved functional status and decrease in hospitalization. However, previous studies did not focus on right ventricular dysfunction as an important pathophysiologic component of cardiorenal syndrome.MethodsIn a prospective cohort study PD was started in 40 patients with refractory right HF (with/without left HF). Refractoriness to conservative therapy was defined as persistent right heart congestion/ascites with intensified diuretic treatment and/or ≥2 hospitalizations within 6 months because of cardiac decompensation despite optimal medical treatment, and/or acute renal failure during intensified conservative treatment of cardiac decompensations.ResultsPatient survival was 55.0% at 1 year, 35.0% at 2 years and 27.5% at 3 years. The number of hospitalization days declined after initiation of PD for both cardiac [13 (IQR 1-53) days before vs. 1 (IQR 0-12) days after start of PD, p<0.001] and unplanned reasons [12 (IQR 3-44) days before vs. 1 (IQR 0-33) days after start of PD, p = 0.007]. Using a combined endpoint including survival time of ≥1 year and either improvement in quality of life or decline in hospitalizations we found that patients with extended ascites, higher systolic pulmonary artery pressure, more marked impairment of right ventricular function and tricuspid valve insufficiency, higher residual renal function as well as those who could perform PD without assistance have benefited most from this therapy.ConclusionsPatients with more pronounced backward failure, less marked residual renal functional impairment and those not depending on assistance for therapy are likely to profit most from PD.

Project description:The renewed interest in tricuspid valve pathology is a consequence of the high mortality rate associated with this valve dysfunction, mostly functional, and secondary to left ventricular impairment, or pulmonary hypertension. Despite the clear relationship between tricuspid insufficiency and mortality, surgical treatment is offered to a small group of patients, due to the significant in-hospital mortality secondary also to the multiple comorbidities and the advanced stage of left ventricular dysfunction. During the last few years, new therapeutic options have been developed for the percutaneous treatment of tricuspid insufficiency which, albeit still in the experimental phase, provides an alternative to surgery in patients at very high-risk or frankly inoperable. We will describe the various percutaneous therapeutic options available today, and their potential application to clinical practice.

Project description:ImportanceIndwelling peritoneal catheters (IPCs) are frequently used to drain tense, symptomatic, malignant ascites. Large-volume drainage may lead to hyponatremia owing to massive salt depletion. To date, no studies have examined the epidemiology of hyponatremia after placement of an IPC.ObjectiveTo evaluate the incidence of hyponatremia after IPC placement, the risk factors associated with its development, and how it is managed.Design, setting, and participantsThis cohort study retrospectively reviewed the medical records of 461 patients who had IPCs placed during the period between 2006 and 2016 at a tertiary care hospital in Boston, Massachusetts, of whom 309 patients met the inclusion criteria. Data analysis was performed from June to November 2019.Main outcomes and measuresMain outcomes were the incidence of hyponatremia (with a serum sodium level <135 mEq/L) after IPC placement, the risk factors for its development, and how it was managed. We also examined the clinical course of a subset of 21 patients with hypovolemic hyponatremia.ResultsOf the 309 eligible patients with laboratory results both before IPC placement and 2 days or more after IPC placement, 189 (72.1%) were female, and the mean (SD) age was 59 (12) years. The overall incidence of hyponatremia after IPC placement was 84.8% (n = 262), of whom 21 patients (8.0%) had severe hyponatremia. The mean (SD) decrease in serum sodium level before vs after IPC placement was 5 (5.1) mEq/L and decreased by 10 mEq/L or more among 52 patients (16.8%). Patients with hyponatremia prior to IPC placement had an 8-fold higher adjusted odds of having persistent hyponatremia after IPC placement (odds ratio, 7.9; 95% CI, 2.9-21.7). Patients with hepatopancreatobiliary malignant neoplasms were more likely to develop hyponatremia (78 of 262 patients with hyponatremia [29.8%] vs 7 of 47 patients without hyponatremia [14.9%]). Hyponatremia was either unrecognized or untreated in 189 patients (72.1%).Conclusions and relevanceAlthough the placement of an IPC is often a palliative measure, hyponatremia is common and is often untreated or unrecognized. Patients at highest risk, such as those with hyponatremia at baseline and those with hepatopancreatobiliary malignant neoplams, should be evaluated carefully prior to IPC placement and may warrant closer monitoring after placement. In all cases, hyponatremia should be evaluated and managed within the context of a patient's overall goals of care.

Project description:Background and objectivesRefractory ascites markedly worsens prognosis in cirrhosis. Large volume paracentesis (LVP) is standard treatment, but complications are common. In a randomized controlled case-series, we assessed a permanent tunneled peritoneal catheter versus LVP in patients with cirrhosis and ascites.Materials and methodsRandom allocation was computer-generated, and concealment used opaque envelopes. Patients were included from January 2017 to December 2018. Inclusion criteria were cirrhosis and recurrent ascites and expected survival of more than 3 months.ResultsThirteen patients were enrolled (PleurX =6 versus LVP = 7). Seven were female, ranging in age from 51 to 80 years. No procedure-related complications occurred. Two patients died due to variceal bleeding (PleurX-group) and sepsis (LVP-group). One patient was withdrawn due to hyponatremia (PleurX-group). Two patients were withdrawn due to bacterial peritonitis and infection of unknown origin (control-group). In the PleurX-group, all patients colonized the catheter, two developed bacterial peritonitis. The most common bacterial colonization was Staph. Epidermidis (n = 4).ConclusionsIn selected patients, the PleurX catheter mobilizes ascites and may be an alternative to LVP. The risk of infection should be considered in each case. The impact of colonization and risk of infections needs further investigation. The present trial does not allow for statistical conclusions.

Project description:Torrential tricuspid regurgitation may lead to heart failure and poor survival and quality of life. Heterotopic transcatheter tricuspid replacement is increasingly offered to patients unsuitable for direct valve repair or replacement. We describe 1 patient treated by transcatheter implantation of 2 self-expanding valves in the venae cavae with a multimodality imaging approach. (Level of Difficulty: Advanced.).

Project description:This research aimed to identify protein biomarkers of right ventricular dysfunction in patients with advanced heart failure with reduced ejection fraction (HFrEF). Samples of myocardium from both, right and left ventricles (RV, LV) were obtained from 10 HFrEF patients with right ventricular dysfunction (RVD), 10 HFrEF patients without RVD (noRVD) undergoing heart transplantation, and 10 non-failing unused donor hearts (Control). Tissue samples were homogenized and extracted using mild Triton X-100 detergent and processed by SP3 extraction to remove the detergent prior the analysis, (LFQ) proteomic analysis identified a total of 4 032 proteins in the left ventricle and 3 788 proteins in the right ventricle.

Project description:Refractory congestive heart failure (RCHF) is a common complication in the natural history of advanced heart failure. Peritoneal dialysis (PD) is a possible alternative in those patients, but studies are scarce, and mostly with small samples. We conducted this meta-analysis to evaluate the effects of PD in patients with RCHF. Articles published before July 2020 in the following databases: PubMed, Web of Science, and CENTRAL. Mean differences (MD) and 95% confidence intervals (CIs) were computed to generate a pooled effect size with a random effects model. We also assessed heterogeneity, risk of bias, publication bias, and quality of evidence. Twenty observational studies (n = 769) were included, with a "before and after intervention" design. PD was associated with a significant reduction in NYHA functional class (MD -1.37, 95% CI -0.78 to -1.96) and length of hospitalisation (MD -34.8, 95% CI -20.6 to -48.9 days/patient/year), a small but significant increase in left ventricular ejection fraction (MD 4.3, 95%CI 1.9 to 6.8%) and a non-significant change in glomerular filtration rate (MD -3.0, 95% CI -6.0 to 0 mL/min/1.73m2). Heterogeneity among studies was significant and overall risk of bias was rated from moderate to critical. No significant publication bias was found, and the overall quality of evidence was very low for all outcomes. PD in patients with RCHF improved functional class, length of hospitalisation, and ventricular functional, and had no impact in renal function. Further randomised clinical trials are warranted to confirm our results that showed some limitations.

Project description:Right heart failure is the cause of death of most patients with severe pulmonary arterial hypertensive (PAH) disorders, yet little is known about the cellular and molecular causes of right ventricular failure (RVF). We first showed a differential gene expression pattern between normal rat right and left ventricles, and postulated the existence of a molecular right heart failure program that distinguishes RVF from adaptive right ventricular hypertrophy (RVH), and that may differ in some respects from a left heart failure program. By means of microarrays and transcriptional sequencing strategies, we used two models of adaptive RVH to characterize a gene expression pattern reflective of growth and the maintenance of myocardial structure. Moreover, two models of RVF were associated with fibrosis, capillary rarefaction, the decreased expression of genes encoding the angiogenesis factors vascular endothelial growth factor, insulin-like growth factor 1, apelin, and angiopoeitin-1, and the increased expression of genes encoding a set of glycolytic enzymes. The treatment of established RVF with a β-adrenergic receptor blocker reversed RVF, and partly reversed the molecular RVF program. We conclude that normal right and left ventricles demonstrate clearly discernable differences in the expression of mRNA and microRNA, and that RVH and RVF are characterized by distinct patterns of gene expression that relate to cell growth, angiogenesis, and energy metabolism.

Project description:Mechanisms of right ventricular (RV) dysfunction in heart failure (HF) are poorly understood. RV response to volume overload (VO), a common contributing factor to HF, is rarely studied. The goal was to identify interventricular differences in response to chronic VO. Rats underwent aorto-caval fistula (ACF)/sham operation to induce VO. After 24 weeks, RV and left ventricular (LV) functions, gene expression and proteomics were studied. ACF led to biventricular dilatation, systolic dysfunction and hypertrophy affecting relatively more RV. Increased RV afterload contributed to larger RV stroke work increment compared to LV. Both ACF ventricles displayed upregulation of genes of myocardial stress and metabolism. Most proteins reacted to VO in a similar direction in both ventricles, yet the expression changes were more pronounced in RV (pslope: < 0.001). The most upregulated were extracellular matrix (POSTN, NRAP, TGM2, CKAP4), cell adhesion (NCAM, NRAP, XIRP2) and cytoskeletal proteins (FHL1, CSRP3) and enzymes of carbohydrate (PKM) or norepinephrine (MAOA) metabolism. Downregulated were MYH6 and FAO enzymes. Therefore, when exposed to identical VO, both ventricles display similar upregulation of stress and metabolic markers. Relatively larger response of ACF RV compared to the LV may be caused by concomitant pulmonary hypertension. No evidence supports RV chamber-specific regulation of protein expression in response to VO.

Project description:BACKGROUND:Chronic heart failure (CHF) is the most common reason for hospital admissions in Germany. For the National Disease Management Guideline (NDMG) on CHF, a multidisciplinary expert panel revised the chapters on drug therapy, invasive therapy, and care coordination, following the methods of evidence-based medicine. METHODS:Recommendations are based on international guideline adaptations or systematic literature search. They were developed by a multidisciplinary expert panel, approved in a formal consensus procedure, and tested in open consultation, as specified by the requirements for S3 guidelines. RESULTS:The pharmacological treatment is based on ACE inhibitors, beta-blockers and mineralocorticoid receptor antagonists as well as diuretics to treat fluid retention, if present. Sacubitril/Valsartan and ivabradine showed positive effects on mortality in large but methodologically limited RCT. They are recommended if established combination therapy is not sufficient for symptom control, or if drugs are not tolerated/contraindicated. The indications for pacemakers or defibrillators have been confined to patient subgroups in which clinical trials have shown a clear benefit. Moreover, the goals of treatment and the patient's expectations should be aligned with each other. Structured care programs, specialized nurses, remote, or telephone monitoring showed moderate effects on patient related outcomes in RCT. CONCLUSION:All patients with heart failure are suggested to be enrolled in a structured program (e.g., a disease management program) including coordinated multidisciplinary care and continuous educational interventions. In patients with a poor prognosis, more intensive care is recommended, e.g. specialized nurses, or telephone support.
