Abstract
Acute right heart failure (ARHF) arises when the right ventricle fails to pump blood efficiently to the pulmonary circulation. This inefficiency leads to a decreased blood supply to various organs. ARHF is a significant health concern, often leading to increased hospital admissions and being associated with a higher risk of mortality. This condition underscores the importance of effective cardiac care and timely intervention to manage its complications and improve patient outcomes. Diagnosing ARHF involves a comprehensive approach that includes a physical examination to evaluate the patient's fluid status and heart-lung function, blood tests to identify potential triggers and help forecast patient outcomes and various imaging techniques. These imaging techniques include electrocardiograms, point-of-care ultrasounds, computed tomography, cardiac magnetic resonance imaging, and other advanced monitoring methods. These diagnostic tools collectively aid in a detailed assessment of the patient's cardiac and pulmonary health, essential for effective management of ARHF. The management of ARHF focuses on addressing the underlying causes, regulating fluid balance, and enhancing cardiac function through pharmacological treatments or mechanical support aimed at boosting right heart performance. This management strategy includes the use of medications that modulate preload, afterload, and inotropy; vasopressors; anti-arrhythmic drugs; ensuring proper oxygenation and ventilation; and the utilization of heart and lung assist devices as a bridge to potential transplantation. This review article is dedicated to exploring the pathophysiology of ARHF, examining its associated morbidity and mortality, evaluating the various diagnostic tools available, and discussing the diverse treatment modalities. The article seeks to provide a comprehensive understanding of ARHF, its impact on health, and the current strategies for its management.

Abstract
Patients with pulmonary arterial hypertension (PAH) who are admitted to the hospital pose a challenge to the multidisciplinary healthcare team due to the complexity of the pathophysiology of their disease state and PAH-specific medication considerations. Pulmonary arterial hypertension is a progressive disease that may lead to death as a result of right ventricular (RV) failure. During acute on chronic RV failure it is critical to decrease the pulmonary vascular resistance with the goal of improving RV function and prognosis; therefore, aggressive PAH-treatment based on disease risk stratification is essential. Pulmonary arterial hypertension treatment for acute on chronic RV failure can be impacted by end-organ damage, hemodynamic instability, drug interactions, and PAH medications dosage and delivery. Sotatercept, a first in class activin signaling inhibitor that works on the bone morphogenetic protein/activin pathway is on track for Food and Drug Administration approval for the treatment of PAH based on results of recent trials in where the medication led to clinical and hemodynamic improvements, even when added to traditional PAH-specific therapies. The purpose of this review is to highlight important considerations when starting or continuing sotatercept in patients admitted to the hospital with PAH.

Abstract
Pulmonary hypertension (PH) often complicates chronic lung disease. However, there are few reports of PH associated with diffuse panbronchiolitis, and there is no effective treatment. We herein report a 64-year-old woman diagnosed with PH due to diffuse panbronchiolitis. She received erythromycin, carbocysteine, and home oxygen therapy (1 L O2/min). After 4 months of therapy, the respiratory function (diffusing capacity of the lungs for carbon monoxide: 23.3% to 76.1%) and PH (mean pulmonary arterial pressure: 50 to 28 mmHg; pulmonary vascular resistance: 680 to 518 dynes・sec・cm-5; pre- vs post-therapy, respectively) had improved markedly.

Abstract
Pulmonary arterial hypertension (PAH) is defined as an elevated mean pulmonary artery pressure (mPAP) of >20 mmHg together with a pulmonary arterial wedge pressure (PAWP) of ≤15 mmHg and pulmonary vascular resistance (PVR) of>2 Wood units (WU). Although the total mortality of pregnant women with PAH has decreased significantly in recent years and is reported to be around 12% in some databases, total mortality is still at an unacceptably high percentage. Moreover, some subgroups, such as patients with Eisenmenger's syndrome, have a particularly high mortality rate of up to 36%. Pregnancy in patients with PAH is contraindicated; its appearance is an indication for a planned termination. Education of patients with PAH, including counseling on effective contraception, is essential. During pregnancy, blood volume, heart rate, and cardiac output increase, while PVR and systemic vascular resistance decrease. The hemostatic balance is shifted towards hypercoagulability. Among PAH-specific drugs, the use of inhaled or intravenous prostacyclins, phosphodiesterase inhibitors, and calcium channel blockers (in patients with preserved vasoreactivity) is acceptable. Endothelin receptor antagonists and riociguat are contraindicated. Childbirth can take place through either vaginal delivery or caesarean section; similarly, neuraxial and general anesthesia have proven indications. In a situation where all pharmacological options have been used in pregnant or postpartum patients in a serious condition, veno-arterial ECMO is a useful therapeutic option. For PAH patients who want to become mothers, an option that does not endanger their lives is adoption.

Abstract
Postcardiotomy cardiogenic shock represents the most serious expression of low cardiac output syndrome after cardiac surgery. Although infrequent, it is a relevant condition due to its specific and complex pathophysiology and important morbidity-mortality. The diagnosis requires a high index of suspicion and multimodal hemodynamic monitoring, where echocardiography and the pulmonary arterial catheter play a main role. Early and multidisciplinary management should focus on the management of postoperative or mechanical complications and the optimization of determinants of cardiac output through fluid therapy or diuretic treatments, inotropic drugs and vasopressors/vasodilators and, in the absence of a response, early mechanical circulatory support. The aim of this paper is to review and update the pathophysiology, diagnosis and management of postcardiotomy cardiogenic shock.

Abstract
Positive-pressure inspiration and positive end-expiratory pressure (PEEP) increase pleural, alveolar, lung transmural, and intra-abdominal pressure, which decrease right and left ventricular (RV; LV) preload and LV afterload and increase RV afterload. The magnitude and clinical significance of the resulting changes in ventricular function are determined by the delivered tidal volume, the total level of PEEP, the compliance of the lungs and chest wall, intravascular volume, baseline RV and LV function, and intra-abdominal pressure. In mechanically ventilated patients, the most important, adverse consequences of respiratory-cardiovascular interactions are a PEEP-induced reduction in cardiac output, systemic oxygen delivery, and blood pressure; RV dysfunction in patients with ARDS; and acute hemodynamic collapse in patients with pulmonary hypertension. On the other hand, the hemodynamic changes produced by respiratory-cardiovascular interactions can be beneficial when used to assess volume responsiveness in hypotensive patients and by reducing dyspnea and improving hypoxemia in patients with cardiogenic pulmonary edema. Thus, a thorough understanding of the physiological principles underlying respiratory-cardiovascular interactions is essential if critical care practitioners are to anticipate, recognize, manage, and utilize their hemodynamic effects. © 2022 American Physiological Society.

Abstract
BACKGROUND Patients with acute decompensation of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) admitted to intensive care unit (ICU) have high in-hospital mortality. We hypothesized that pulmonary hypertension (PH) severity, measured by a simplified version of European Society of Cardiology/European Respiratory Society (ESC/ERS) risk assessment, and the severity of organ dysfunction upon ICU admission, measured by sequential organ failure assessment score (SOFA) were associated with in-hospital mortality in decompensated patients with PAH and CTEPH. We also described clinical and laboratory variables during ICU stay. METHODS Observational study including adults with decompensated PAH or CTEPH with unplanned ICU admission between 2014 and 2019. Multivariate logistic regression models were used to evaluate the association of ESC/ERS risk assessment and SOFA score with in-hospital mortality. ESC/ERS risk assessment and SOFA score were included in a decision tree to predict in-hospital mortality. RESULTS 73 patients were included. In-hospital mortality was 41.1%. ESC/ERS high-risk group (adjusted odds ratio = 95.52) and SOFA score (adjusted odds ratio = 1.80) were associated with in-hospital mortality. The decision tree identified four groups with in-hospital mortality between 8.1% and 100%. Nonsurvivors had a lower central venous oxygen saturation, higher arterial lactate and higher brain natriuretic peptide in the end of first week in the ICU. CONCLUSIONS High-risk on a simplified version of ERS/ESC risk assessment and SOFA score upon ICU admission are associate with in-hospital mortality. A decision tree based on ESC/ERS risk assessment and SOFA score identifies four groups with in-hospital mortality between 8.1% and 100%.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) represents the later stage consequence of at least one or more unresolved episodes of acute pulmonary embolism; thus, indefinite anticoagulation is strongly recommended by current practice guidelines. Historically, vitamin K antagonists have been widely used in these patients. However, recent data indicate a shift toward direct oral anticoagulants (DOACs), despite lack of data on the safety and efficacy in this patient population. Herein, we briefly discuss the current rationale for oral anticoagulation use in CTEPH, addressing important issues and controversies involved with the use of DOACs, opening a strategy for further clinical research in the field of oral anticoagulation.

Abstract
Sarcoidosis is a systemic inflammatory disease defined by the presence of aberrant granulomas affecting various organs. Due to its multisystem involvement, care of patients with established sarcoidosis becomes challenging, especially in the intensive care setting. While the lungs are typically involved, extrapulmonary manifestations also occur either concurrently or exclusively within a significant proportion of patients, complicating diagnostic and management decisions. The scope of this review is to focus on what considerations are necessary in the evaluation and management of patients with known sarcoidosis and their associated complications within a cardiopulmonary and critical care perspective.

Abstract
Cardio-surgical patient care requires a comprehensive and multidisciplinary approach to develop strategies to improve patient safety and outcomes. In the preoperative period, prophylaxis for frequent postoperative complications, such as de novo atrial fibrillation or bleeding, and prehabilitation based on exercise training, respiratory physiotherapy and nutritional and cognitive therapy, especially in fragile patients, stand out. There have been great advances, during the intraoperative phase, such as minimally invasive surgery, improved myocardial preservation, enhanced systemic perfusion and brain protection during extracorporeal circulation, or implementation of Safe Surgery protocols. Postoperative care should include goal-directed hemodynamic theraphy, a correct approach to coagulation disorders, and a multimodal analgesic protocol to facilitate early extubation and mobilization. Finally, optimal management of postoperative complications is key, including arrhythmias, vasoplegia, bleeding, and myocardial stunning that can lead to low cardiac output syndrome or, in extreme cases, cardiogenic shock. This global approach and the high degree of complexity require highly specialised units where intensive care specialists add value and are key to obtain more effective and efficient clinical results.

Abstract
Coronavirus disease 2019 (COVID‐19) causes a pandemic around the globe. Debilitating and even deadly complications have occurred to the millions. A recent study reported 31% of right ventricular dilation in the hospitalized COVID‐19 patients, which is significantly associated with the mortality. Therefore, we sought to search for the lines of evidence in the literature that COVID‐19 may contribute to right heart dysfunction. The relevant literature and data from PubMed, Embase, Cochrane Library databases, and Web of Science were searched using the MeSH terms including ‘COVID‐19’, ‘SARS‐CoV‐2’, ‘novel coronavirus pneumonia’, ‘novel coronavirus’, ‘right heart failure’, ‘right heart dysfunction’, ‘pulmonary hypertension’, ‘pulmonary embolism’, and various combinations. The collected literature and data were sorted and summarized. Literature reports that angiotensin‐converting enzyme 2 (ACE2) is the host receptor mediating the cell entry of severe acute respiratory syndrome coronavirus 2. Clinical and experimental evidence shows that loss of function of ACE2 aggravates pulmonary hypertension and gain of function of ACE2 exerts protection on cardiopulmonary circulation. Moreover, the patients with COVID‐19 are more susceptible to pulmonary embolism and severe pneumonia‐induced acute respiratory distress syndrome. Therefore, COVID‐19 may cause right heart dysfunction by inducing pulmonary hypertension, pulmonary embolism, and acute respiratory distress syndrome. Particular attention should be paid to the function of the right heart, the overlooked chamber in COVID‐19. Blood gas analysis, laboratory test of cardiac injury markers, physical examination, and echocardiography should be performed to identify right heart failure as early as possible. Once the right heart failure is confirmed, the therapeutic modalities following the guidelines of European Society of Cardiology should be employed to reduce mortality.

Abstract
This study aimed to ascertain whether endoplasmic reticulum (ER) stress participates in acute lung injury (ALI) and related right ventricular dysfunction (RVD) as well as to explore the underlying mechanisms of these conditions. A single intratracheal instillation of lipopolysaccharide (LPS) (10 mg/kg) was used to establish the RVD model. The ER stress inhibitor, 4-PBA (500 mg/kg), was administered using a gavage 2 hours before and after the LPS treatment for prevention and treatment, respectively. At 12 hours post-LPS exposure, mRNA and protein expressions of ER stress-specific biomarkers, glucose regulating protein 78 (GRP78) and CCAAT/enhancer binding protein homology (CHOP), were significantly upregulated. This effect was inhibited by both 4-PBA prevention and treatment. In addition, echocardiography showed that 4-PBA improved the LPS-induced abnormality in the tricuspid annular plane systolic excursion (TAPSE) and the right ventricular end-diastolic diameter (RVEDD), however not in the pulmonary artery acceleration time (PAAT). Furthermore, hematoxylin and eosin staining (HE) and terminal transferase dUTP nick end labeling (TUNEL) assays revealed that the proportion of proapoptotic cells was higher in RVD rats. This was prominently ameliorated by 4-PBA treatment. Moreover, 4-PBA had a similar reverse effect on the LPS-induced increase in the Bax/Bcl-2 ratio, caspase-12, and caspase-3 expressions as revealed by western blotting. Furthermore, 4-PBA improved LPS-induced right ventricle (RV) myeloperoxidase (MPO)-positive neutrophil infiltration percentage, inhibited nuclear factor kappa B (NF-κB) activity, and reduced the expressions of inflammatory cytokines, TNF-α, IL-1β, and IL-6, in serum and RV. Taken together, our results indicated that ER stress-mediated apoptosis and inflammation might contribute to the development of ALI-related RVD induced by intratracheal LPS instillation. Gavage-administered 4-PBA could improve right ventricle (RV) systolic dysfunction and dilation, plausibly by blocking ER stress.

Abstract
Pulmonary hypertension (PH) is the condition of elevated pressures in the pulmonary circulation. PH can develop acutely in patients with critical illness such as acute respiratory distress syndrome, sepsis, massive pulmonary embolism, left ventricular dysfunction, or after surgery. In a cancer patient, unique etiologies such as myeloproliferative disorders, tyrosine kinase inhibitors, or tumor emboli may result in PH. Early recognition and treatment of the causative condition may reverse acute PH or return chronic PH to its baseline status. Progression of the disease or its decompensation due to infection, a thromboembolic event, or other triggers can lead to admission to an intensive care unit. Regardless of etiology, the development or worsening of PH may precipitate hypoxemia, hemodynamic instability, or right ventricular failure, which can be challenging to manage or even fatal. In select cases, rapid institution of advanced treatment modalities may be warranted. This chapter reviews the etiology, epidemiology, pathophysiology, clinical features, diagnosis, and prognosis of PH and presents a comprehensive analysis of PH and right heart failure management strategies in the critical care setting. In particular, a unique perspective on oncologically relevant PH is provided.

Abstract
Pulmonary hypertension (PH) is a condition associated with high morbidity and mortality. Patients with PH who require critical care usually have severe right ventricular (RV) dysfunction. Although different groups of PH have different etiologies, pulmonary vascular dysfunction is common in these groups. PH can lead to increased pulmonary artery pressure, which can ultimately cause RV failure. Clinicians should be familiar with the presentations of this disease and diagnostic tools. The contributing factors, if present (e.g., sepsis), and coexisting conditions (e.g., arrhythmias) should be identified and addressed accordingly. The preload should be optimized by fluid administration, diuretics, and dialysis, if necessary. On the other hand, the RV afterload should be reduced to improve the RV function with pulmonary vasodilators, such as prostacyclins, inhaled nitric oxide, and phosphodiesterase type 5 inhibitors, especially in group 1 PH. Inotropes are also used to improve RV contractility, and if inadequate, use of ventricular assist devices and extracorporeal life support should be considered in suitable candidates. Moreover, vasopressors should be used to maintain systemic blood pressure, albeit cautiously, as they increase the RV afterload. Measures should be also taken to ensure adequate oxygenation. However, mechanical ventilation is avoided in RV failure. In this study, we reviewed the pathophysiology, manifestations, diagnosis, monitoring, and management strategies of PH, especially in intensive care units.
