Aim: Significant tricuspid regurgitation (TR) is common in heart failure (HF) and portends poor prognosis. We sought to determine whether the poor outcome results from the TR itself, or whether the TR is a surrogate marker of advanced left-sided myocardial or valvular heart disease. Methods and results: We studied 639 patients admitted for acute HF. The relationship between TR severity and the endpoint of readmission for HF or mortality was assessed after adjustment for multiple clinical and echocardiographic parameters...

We have previously developed a simulated cardiovascular physiology model for in-silico testing and validation of novel closed-loop controllers. To date, a detailed model of the right heart and pulmonary circulation was not needed, as previous controllers were not intended for use in patients with cardiac or pulmonary pathology. With new development of controllers for vasopressors, and looking forward, for combined vasopressor-fluid controllers, modeling of right-sided and pulmonary pathology is now relevant to further in-silico validation, so we aimed to expand our existing simulation platform to include these elements...

CLINICAL INTRODUCTION: A 26-year-old man with an unremarkable medical history sensed a momentary retrosternal 'pop' followed by overwhelming dyspnoea, without reporting any prodromal symptoms. At the emergency department, he had a significant tachycardia (170 bpm) and an extreme low diastolic blood pressure (<30 mm Hg). A loud, harsh and continuous murmur could be maximally auscultated at the right lower sternal border. ECG revealed global ST depression with ST elevation in lead aVR...

Patients with submassive pulmonary embolism (PE), although normotensive, are characterized by right ventricular (RV) dysfunction and elevated levels of biomarkers of cardiac damage. The best treatment option in these cases is still a subject of debate and the use of thrombolysis in submassive PE remains controversial. A 57-year-old Caucasian male with unprovoked PE, normal blood pressure, and elevated troponin I values was referred to the cardiovascular department. In view of the presence of a right atrium thrombus, the patient underwent surgical embolectomy under extracorporeal circulation, with the extraction of a huge thrombus together with fragmented thrombi from both pulmonary arteries...

PURPOSE OF REVIEW: Acute heart failure continues to be a challenge as there is limited benefit of numerous agents that have been tested. Cardiac resynchronization therapy remains standard of care, yet timing and need for implantable cardiac defibrillator has been brought into question with the recent randomized trials. Several recent advances have been made towards management of heart failure both in drug and device therapy. The purpose of this review is to provide an update on the most important recent studies on heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF)...

Pulmonary embolism (PE) represents a prevalent cause of morbidity and mortality in the United States, with approximately 600 000 cases diagnosed annually. The mortality rate for untreated PE is as high as 30%. Right ventricular (RV) dysfunction is a sign of possible adverse outcomes with right-sided heart failure being the usual cause of death from PE. There is a spectrum of clinical presentations associated with PE diagnoses, from incidental and asymptomatic to rapid hemodynamic collapse. Despite successes in identifying patients with "high-risk" PEs for aggressive thrombolytic interventions and "low-risk" PEs for outpatient anticoagulation, a significant lack of consensus exists regarding intervention modalities for PEs identified as "intermediate risk" or "submassive," defined as normotensive (systolic blood pressure ≥90 mm Hg) with acute RV dysfunction and myocardial injury...

OBJECTIVE: Surgical therapy for refractory primary cardiogenic shock is largely based on emergent placement of extracorporeal membrane oxygenation or short-term ventricular assist devices. We have adopted a strategy of routine implantation of durable left ventricular assist devices (LVAD) as initial therapy for refractory cardiogenic shock, in patients who are potential candidates for heart transplantation, and report our experience. METHODS: Retrospective review of 43 consecutive patients with refractory shock caused by acute myocardial infarction (n = 21) or acute decompensated heart failure (n = 22) who were treated with primary implantation of a durable LVAD in a single institution...

AIMS: Congestion is a central feature of acute heart failure (HF) and its assessment is important for clinical decisions (e.g. tailoring decongestive treatments). It remains uncertain whether patients with acute HF with preserved ejection fraction (HFpEF) are comparably congested as in acute HF with reduced EF (HFrEF). This study assessed congestion, right ventricular (RV) and renal dysfunction in acute HFpEF, HFrEF and non-cardiac dyspnoea. METHODS AND RESULTS: We compared echocardiographic and circulating biomarkers of congestion in 146 patients from the MEDIA-DHF study: 101 with acute HF (38 HFpEF, 41 HFrEF, 22 HF with mid-range ejection fraction) and 45 with non-cardiac dyspnoea...

There is a growing interest in the use of percutaneously delivered ventricular assist devices (PVAD) in the pediatric patient population. A 16 year old female and 18 year old male both status post heart transplantation presented with evidence of graft rejection and acute severe global systolic and diastolic heart failure necessitating hemodynamic catheterization and inotropic support. Both underwent percutaneous Impella CP LVAD (Abiomed, Danvers, MA) placement with close monitoring of right ventricular function...

The aim of this study was to describe the echocardiographic trend of left ventricular (LV) and right ventricular (RV) function after implantation of a pulsatile flow left ventricular assist device (LVAD) in children. From 2013 to 2016, we prospectively evaluated 13 consecutive pediatric Berlin Heart EXCOR LVAD patients. Clinical and echocardiographic data were collected at baseline, within 24 h after implantation and monthly until LVAD explant. Median age and weight at the implantation was 8 (4-23) months and 5 (4...

Postoperative right-sided heart failure (RHF) is a common complication after continuous-flow left ventricular assist device implantation. Studies have examined RHF in the perioperative period, but few have assessed late-onset RHF. We analyzed the incidence of early and late RHF in patients with HeartMate II and HeartWare left ventricular assist devices and associated morbidity, mortality, and independent predictors of RHF. We retrospectively analyzed records of 526 patients with chronic heart failure who underwent continuous-flow left ventricular assist device implantation; 147 (27...

To establish the experts consensus on the right heart function management in critically ill patients. The panel of consensus was composed of 30 experts in critical care medicine who are all members of Critical Hemodynamic Therapy Collaboration Group (CHTC Group). Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. Then the Delphi method was adopted by 52 experts to reassess all the statements.

The molecular mechanism underlying acute right heart failure (RHF) is poorly understood. We used pulmonary artery banding (PAB) to induce acute RHF characterized by a rapid rise of right ventricular pressure, and then a decrease in right ventricular pressure along with a decrease in blood pressure right after banding. We found higher brain natriuretic peptide (BNP) and beta-myosin heavy chain (βMHC) levels and lower alpha-myosin heavy chain (αMHC) levels in RHF rats than sham-operated rats. Hemodynamic indexes in rats with acute RHF were slightly improved by trimedazidine TMZ, a key inhibitor of fatty acid (FA) oxidation...

Aims: Cardiac inflammation has been suggested to be regulated by the sympathetic nervous system (SNS). However, due to the lack of methodology to surgically eliminate the myocardial SNS in mice, neuronal control of cardiac inflammation remains ill defined. Here, we report a procedure for local cardiac sympathetic denervation in mice and tested its effect in a mouse model of heart failure post myocardial infarction. Methods and Results: Upon preparation of the carotid bifurcation the right and left superior cervical ganglion were localized and their pre- and postganglionic branches dissected before removal of the ganglion...

BACKGROUND: Acutely decompensated heart failure (ADHF) presents high morbidity and mortality in spite of therapeutic advance. Identifying factors of worst prognosis is important to improve assistance during the hospital phase and follow-up after discharge. The use of echocardiography for diagnosis and therapeutic guidance has been of great utility in clinical practice. However, it is not clear if it could also be useful for risk determination and classification in patients with ADHF and if it is capable of adding prognostic value to a clinical score (OPTIMIZE-HF)...

Tacrolimus is an immunosuppressive agent well known to be capable of producing renal impairment. Acute renal failure with right heart failure caused by tacrolimus is rarely described. We report the findings of one such case in which tacrolimus caused acute renal failure with severe tricuspid regurgitation and right ventricular failure documented by echocardiography.

Pulmonary hypertension (PH), remains a challenging disease with a large impact on both humans and meat-type chickens. PH is characterized by the onset of idiopathic pulmonary arterial hypertension leading to right ventricular failure. In this experiment relative gene expression of adenosine A1 receptor (ADORA1), serotonin transporter (SERT), phosphodiesterase 5A (PDE5) and troponin T2 were compared in hearts from broilers with acute right ventricular failure and from healthy birds. There were major increases in adenosine A1 receptor (177%) and serotonin transporter (475%), and more modest but significant increases in PDE5 (146%) and troponin T2 (140%) gene expressions in broilers with right ventricular failure compared to healthy birds (P<0...

BACKGROUND: The development of heart failure after acute myocardial infarction (MI) was related to left ventricular (LV) pathological remodeling and dysfunction. Cardiac stem cells (CSCs) provided a new option to treat acute MI. This study was to investigate the effects of CSCs on structural and functional alteration in acute MI. METHODS: Acute MI was induced in 20 Sprague-Dawley rats by ligation of the left anterior descending coronary artery. Two weeks after MI, animals were randomized into CSCs or control group...
