- A Portuguese Expert Panel Position Paper on the Management of Heart Failure with Preserved Ejection Fraction - Part II: Unmet Needs and Organization of Care in Portugal.Publication . Silva-Cardoso, José; Moreira, Emília; Tavares de Melo, Rachel; Moraes-Sarmento, Pedro; Cardim, Nuno; Oliveira, Mário; Gavina, Cristina; Moura, Brenda; Araújo, Inês; Santos, Paulo; Peres, Marisa; Fonseca, Cândida; Pedro Ferreira, João; Marques, Irene; Andrade, Aurora; Baptista, Rui; Brito, Dulce; Cernadas, Rui; Dos Santos, Jonathan; Leite-Moreira, Adelino; Gonçalves, Lino; Ferreira, Jorge; Aguiar, Carlos; Fonseca, Manuela; Fontes-Carvalho, Ricardo; Franco, Fátima; Lourenço, Carolina; Martins, Elisabete; Pereira, Hélder; Santos, Mário; Pimenta, JoanaIn Portugal, a 15.2% prevalence of heart failure with preserved ejection fraction (HFpEF) was recently identified among those aged ≥50 years. HFpEF represents 90% of Portuguese heart failure patients. HFpEF management in Portugal is challenging due to patient heterogeneity, diagnostic and therapeutic complexity, and organizational constraints on the healthcare system. Considering the above, a panel of Portuguese experts convened to address HFpEF management within the national context. This was done in a two-paper set. This, the second paper, identifies unmet needs and suggests a set of measures to improve the current organization of HFpEF management in Portugal. Our purpose is to create a multidisciplinary integrated care system, ensuring a seamless connection between hospitals and primary care. Additionally, we propose a practical approach to the management of HFpEF, including a roadmap for screening, diagnosis, referral and treatment. The aim is to help clinicians improve HFpEF management throughout the disease trajectory.

- Efficacy of Peritoneal Dialysis in Patients With Refractory Congestive Heart Failure: a Systematic Review and Meta-AnalysisPublication . Timóteo, AT; Mano, T; SpringerRefractory 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.

- The Accuracy of PiCCO® in Measuring Cardiac Output in Patients Under Therapeutic Hypothermia: Comparison With Transthoracic EchocardiographyPublication . Souto Moura, T; Aguiar Rosa, S; Germano, N; Cavaco, R; Sequeira, T; Alves, M; Papoila, AL; Bento, LBackground: Invasive cardiac monitoring using thermodilution methods such as PiCCO® is widely used in critically ill patients and provides a wide range of hemodynamic variables, including cardiac output (CO). However, in post-cardiac arrest patients subjected to therapeutic hypothermia, the low body temperature possibly could interfere with the technique. Transthoracic Doppler echocardiography (ECHO) has long proved its accuracy in estimating CO, and is not influenced by temperature changes. Objective: To assess the accuracy of PiCCO® in measuring CO in patients under therapeutic hypothermia, compared with ECHO. Design and patients: Thirty paired COECHO/COPiCCO measurements were analyzed in 15 patients subjected to hypothermia after cardiac arrest. Eighteen paired measurements were obtained at under 36°C and 12 at ≥36°C. A value of 0.5l/min was considered the maximum accepted difference between the COECHO and COPiCCO values. Results: Under conditions of normothermia (≥36°C), the mean difference between COECHO and COPiCCO was 0.030 l/min, with limits of agreement (-0.22, 0.28) - all of the measurements differing by less than 0.5 l/min. In situations of hypothermia (<36°C), the mean difference in CO measurements was -0.426 l/min, with limits of agreement (-1.60, 0.75), and only 44% (8/18) of the paired measurements fell within the interval (-0.5, 0.5). The calculated temperature cut-off point maximizing specificity was 35.95°C: above this temperature, specificity was 100%, with a false-positive rate of 0%. Conclusions: The results clearly show clinically relevant discordance between COECHO and COPiCCO at temperatures of <36°C, demonstrating the inaccuracy of PiCCO® for cardiac output measurements in hypothermic patients.
- Quadripolar Left Ventricle Only Single Lead Pacing in a Patient With a Tricuspid Mechanical Valve: a Less Invasive ApproachPublication . Grazina, A; Teixeira, B; Silva Cunha, P; Oliveira, MIn the presence of prosthetic tricuspid valve, the inaccessibility to the right ventricle makes permanent pacing challenging. The placement of a left ventricle (LV) single lead in the coronary sinus (CS) is a well-accepted alternative, with some limitations regarding sensing and threshold. We describe a clinical case of a patient who had a previous LV only lead in the CS due to the presence of a prosthetic tricuspid valve and, after a surgical valvular intervention, presented with recurrent syncope episodes due to lead malfunction with lack of pacing capture and significant ventricular pauses. A quadripolar lead was chosen to be placed in the CS connected to a cardiac resynchronization therapy pacemaker device, programmed at biventricular VVI and using a specific manufacturer T-wave protection algorithm to prevent pacemaker-induced arrhythmias and to use the patient's own rhythm. This approach prevented a fourth surgical intervention to place an epicardial lead and resulted in reasonable LV sensing and pacing threshold. Learning objectives: This paper reports an alternative and atypical approach that could solve some of the limitations associated with ventricular pacing in patients with tricuspid prosthetic valves and multiple previous surgeries.
- Heterotopic Caval Valve-in-Valve Procedure for Prosthetic Migration: Two Case ReportsPublication . Grazina, A; Ferreira, A; Ramos, R; Cacela, DBackground: Heterotopic bicaval stenting or caval valve implantation (CAVI) either with non-dedicated balloon-expandable Sapien™ valves (Edwards Lifesciences) or with dedicated TricValve™ (Products + Features) has emerged as a safe and effective percutaneous treatment for high-risk patients with severe tricuspid regurgitation (TR). One technical difficulty of CAVI is the lack of native calcified structures to anchor the device, which may lead to paravalvular leak or migration. Cases summary: We describe two patients with severe TR and high surgical risk who underwent CAVI procedures, both of them complicated with device migration to the right atrium (one inferior vena cava device and one superior vena cava device). Both cases were treated with a caval valve-in-valve procedure, with good technical and clinical results. Discussion: With the recent development of several percutaneous interventions for high-risk patients with severe TR, the rate of some possible complications is not well established, and neither are the better managing strategies. Device embolization is a rare complication of transcatheter heart interventions but with potential catastrophic consequences. Less invasive strategies such as the valve-in-valve procedure may be preferable in order to avoid the exposure of these patients to complex heart surgeries with extracorporeal circulation.
