Abstract
Pulmonary hypertension (PH) caused by left heart disease, also known as post-capillary PH, is the most common etiology of PH. Left heart disease due to systolic dysfunction or heart failure with preserved ejection fraction, valvular heart disease, and left atrial myopathy due to atrial fibrillation are causes of post-capillary PH. Elevated left-sided filling pressures cause pulmonary venous congestion due to backward transmission of pressures and post-capillary PH. In advanced left-sided heart disease or valvular heart disease, chronic uncontrolled venous congestion may lead to remodeling of the pulmonary arterial system, causing combined pre-capillary and post-capillary PH. The hemodynamic definition of post-capillary PH includes a mean pulmonary arterial pressure > 20 mmHg, pulmonary vascular resistance < 3 Wood units, and pulmonary capillary wedge pressure > 15 mmHg. Echocardiography is important in the identification and management of the underlying cause of post-capillary PH. Management of post-capillary PH is focused on the treatment of the underlying condition. Strategies are geared towards pharmacotherapy and guideline-directed medical therapy for heart failure, surgical or percutaneous management of valvular disorders, and control of modifiable risk factors and comorbid conditions. Referral to centers with advanced heart and pulmonary teams has shown to improve morbidity and mortality. There is emerging interest in the use of targeted agents classically used in pulmonary arterial hypertension, but current data remain limited and conflicting. This review aims to serve as a comprehensive summary of postcapillary PH and its etiologies, pathophysiology, diagnosis, and management, particularly as it pertains to advanced heart failure.

Abstract
Pulmonary hypertension (PH) encompasses a broad range of conditions, including pulmonary artery hypertension, left-sided heart disease, and pulmonary and thromboembolic disorders. Successful diagnosis and management rely on an integrated clinical assessment of the patient's physiology and right heart function. Right ventricular (RV) heart failure is often a result of PH, but may result from varying abnormalities in preload, afterload, and intrinsic myocardial dysfunction, which require distinct management strategies. Consideration of an individual's hemodynamic phenotype and physiologic circumstances is paramount in management of PH and RV failure, particularly when there is clinical instability in the intensive care setting.

Abstract
PURPOSE OF REVIEW The purpose of this review is to provide an overview of assessment of right ventricular function in the context of pulmonary hypertension and pulmonary arterial hypertension (PAH). We will review unique features of right ventricular anatomy, delineation of cause of pulmonary hypertension through careful right ventricular assessment, echocardiographic and hemodynamic evaluation, and the importance of this assessment in prognosis. RECENT FINDINGS The importance of performance in prognosis and risk assessment in patients with pulmonary hypertension has been continually emphasized in ongoing research. Representative parameters of right ventricular function have been shown to be predictive of prognosis in patients with pulmonary hypertension. Further, the importance of serial right ventricular assessment in risk assessment and prognosis has remained an emerging theme. SUMMARY Careful evaluation of right ventricular function is paramount in assessing the cause of pulmonary hypertension and severity of disease. Further, it has prognostic significance, as many representative parameters of right ventricular function have been linked with mortality. In our opinion, right ventricular function should be assessed serially throughout the course of treatment in pulmonary hypertension, and baseline parameters in addition to dynamic changes should be incorporated into risk assessment. Achieving normal or near-normal right ventricular performance may serve as a principal goal in the treatment of pulmonary hypertension.

Am J Cardiol 2023; 201:328-334.

Abstract
Pulmonary arterial hypertension (PAH) is often a progressive, fatal disease. Because of nonspecificity of symptoms and limited awareness of PAH, patients are often diagnosed and referred late to accredited pulmonary hypertension (PH) centers, contributing to worsening survival and overall prognosis. The objective of the present study was to determine if the virtual echocardiography screening tool (VEST), a simple scoring system using routinely reported echocardiographic metrics, could capture earlier diagnoses of PAH before clinical recognition and referral to expert PH centers. This study is a retrospective analysis of 132 patients with PAH evaluated consecutively at 2 accredited referral PH centers. VEST scores and time to evaluation at PH center were quantified based on the first available echocardiogram before referral. Clinical risk assessment was calculated at initial evaluation by the PH center using the REVEAL (Registry to Evaluate Early and Long-term PAH Disease Management) 2.0 calculator. An overwhelming majority (93%) of the study participants had markedly abnormal VEST scores predictive of PAH before evaluation at a PH referral center. The median delay from VEST to evaluation was >6 months at 206 days (quartile 1, quartile 3: 55, 757). At initial evaluation, 72% were intermediate or high-risk based on REVEAL 2.0 risk assessment. In conclusion, we propose that VEST is a powerful yet simple scoring tool that can capture high-risk patients with PAH, prompting earlier diagnosis and referrals to accredited PH centers, and allowing for earlier expert implementation of PH medical therapies.

Abstract
BACKGROUND Among subjects with exercise intolerance and suspected early-stage pulmonary hypertension (PH), early identification of pulmonary vascular disease (PVD) with noninvasive methods is essential for prompt PH management. HYPOTHESIS Rest gas exchange parameters (minute ventilation to carbon dioxide production ratio: VE /VCO2 and end-tidal carbon dioxide: ETCO2 ) can identify PVD in early-stage PH. METHODS We conducted a retrospective review of 55 subjects with early-stage PH (per echocardiogram), undergoing invasive exercise hemodynamics with cardiopulmonary exercise test to distinguish exercise intolerance mechanisms. Based on the rest and exercise hemodynamics, three distinct phenotypes were defined: (1) PVD, (2) pulmonary venous hypertension, and (3) noncardiac dyspnea (no rest or exercise PH). For all tests, *p < .05 was considered statistically significant. RESULTS The mean age was 63.3 ± 13.4 years (53% female). In the overall cohort, higher rest VE /VCO2 and lower rest ETCO2 (mm Hg) correlated with high rest and exercise pulmonary vascular resistance (PVR) (r ~ 0.5-0.6*). On receiver-operating characteristic analysis to predict PVD (vs. non-PVD) subjects with noninvasive metrics, area under the curve for pulmonary artery systolic pressure (echocardiogram) = 0.53, rest VE /VCO2 = 0.70* and ETCO2 = 0.73*. Based on this, optimal thresholds of rest VE /VCO2 > 40 mm Hg and rest ETCO2 < 30 mm Hg were applied to the overall cohort. Subjects with both abnormal gas exchange parameters (n = 12, vs. both normal parameters, n = 19) had an exercise PVR 5.2 ± 2.6* (vs. 1.9 ± 1.2), mPAP/CO slope with exercise 10.2 ± 6.0* (vs. 2.9 ± 2.0), and none included subjects from the noncardiac dyspnea group. CONCLUSIONS In a broad cohort of subjects with suspected early-stage PH, referred for invasive exercise testing to distinguish mechanisms of exercise intolerance, rest gas exchange parameters (VE /VCO2 > 40 mm Hg and ETCO2 < 30 mm Hg) identify PVD.

Abstract
BACKGROUND Right ventricular (RV) dilation has been used to predict adverse outcomes in acute pulmonary conditions. It has been used to categorize the severity of novel coronavirus infection (COVID-19) infection. Our study aimed to use chest CT-angiogram (CTA) to assess if increased RV dilation, quantified as an increased RV:LV (left ventricle) ratio, is associated with adverse outcomes in the COVID-19 infection, and if it occurs out of proportion to lung parenchymal disease. RESULTS We reviewed clinical, laboratory, and chest CTA findings in COVID-19 patients (n = 100), and two control groups: normal subjects (n = 10) and subjects with organizing pneumonia (n = 10). On a chest CTA, we measured basal dimensions of the RV and LV in a focused 4-chamber view, and dimensions of pulmonary artery (PA) and aorta (AO) at the PA bifurcation level. Among the COVID-19 cohort, a higher RV:LV ratio was correlated with adverse outcomes, defined as ICU admission, intubation, or death. In patients with adverse outcomes, the RV:LV ratio was 1.06 ± 0.10, versus 0.95 ± 0.15 in patients without adverse outcomes. Among the adverse outcomes group, compared to the control subjects with organizing pneumonia, the lung parenchymal damage was lower (22.6 ± 9.0 vs. 32.7 ± 6.6), yet the RV:LV ratio was higher (1.06 ± 0.14 vs. 0.89 ± 0.07). In ROC analysis, RV:LV ratio had an AUC = 0.707 with an optimal cutoff of RV:LV ≥ 1.1 as a predictor of adverse outcomes. In a validation cohort (n = 25), an RV:LV ≥ 1.1 as a cutoff predicted adverse outcomes with an odds ratio of 76:1. CONCLUSIONS In COVID-19 patients, RV:LV ratio ≥ 1.1 on CTA chest is correlated with adverse outcomes. RV dilation in COVID-19 is out of proportion to parenchymal lung damage, pointing toward a vascular and/or thrombotic injury in the lungs.

Abstract
Deep phenotyping of pulmonary hypertension (PH) with multimodal diagnostic exercise interventions can lead to early focused therapeutic interventions. Herein, we report methods to simultaneously assess pulmonary impedance, differential biventricular myocardial strain, and right ventricular:pulmonary arterial (RV:PA) uncoupling during exercise, which we pilot in subjects with suspected PH. As proof-of-concept, we show that four subjects with different diagnoses [pulmonary arterial hypertension (PAH); chronic thromboembolic disease (CTEPH); PH due to heart failure with preserved ejection fraction (PH-HFpEF); and noncardiac dyspnea (NCD)] have distinct patterns of response to exercise. RV:PA coupling assessment with exercise was highest-to-lowest in this order: PAH > CTEPH > PH-HFpEF > NCD. Input impedance (Z0) with exercise was highest in precapillary PH (PAH, CTEPH), followed by PH-HFpEF and NCD. Characteristic impedance (ZC) tended to decline with exercise, except for the PH-HFpEF subject (initial Zc increase at moderate workload with subsequent decrease at higher workload with augmentation in cardiac output). Differential myocardial strain was normal in PAH, CTEPH, and NCD subjects and lower in the PH-HFpEF subject in the interventricular septum. The combination of these metrics allowed novel insights into mechanisms of RV:PA uncoupling. For example, while the PH-HFpEF subject had hemodynamics comparable to the NCD subject at rest, with exercise coupling dropped precipitously, which can be attributed (by decreased myocardial strain of interventricular septum) to poor support from the left ventricle (LV). We conclude that this deep phenotyping approach may distinguish afterload sensitive vs. LV-dependent mechanisms of RV:PA uncoupling in PH, which may lead to novel therapeutically relevant insights.

Abstract
While the current definition of pulmonary hypertension (PH) is still based on haemodynamic variables, transthoracic echocardiography is the most important diagnostic clinical tool for the first assessment and evaluation of a patient, in whom PH is suspected. In addition, it is the most important clinical modality in long term follow-up and the utility of echocardiography has widely been demonstrated in patients with PH. Echocardiography not only reveals the underlying cardiac morphology and diagnosis of any associated cardiac defects. In most patients with PH right ventricular (RV) pressure estimation is feasible. In addition, ventricular systolic and diastolic function, as well as ventricular-ventricular interactions of both ventricles can be assessed by using echocardiography. Maximizing the use of echocardiography by reporting several measures to gain information and quantitatively describe the parameters, that are linked to prognosis, seem particularly appealing in these children, in whom other advanced imaging modalities requiring anaesthesia is associated with a considerable risk. Herein we provide a practical approach and a concise and clinically applicable echocardiographic guidance and present basic variables, which should be obtained at any assessment. Moreover, we present additional advanced echocardiographic measures, that can be applied in a research or clinical setting when progressive PH needs a deeper insight to assess heart function, estimation of pulmonary artery pressures among others, by echocardiography. Finally, clinically relevant studies in view of the prognostic properties with a focus on the most important echocardiographic variables in pediatric PH are summarized.

Abstract
Pulmonary hypertension (PH) is a progressive disease affecting patients across the life span. The pathophysiology primarily involves the pulmonary vasculature and right ventricle (RV), but eventually affects the left ventricular (LV) function as well. Safe, accurate imaging modalities are critical for diagnosis, serial monitoring, and tailored therapy. While cardiac catheterization remains the conventional modality for establishing diagnosis and serial monitoring, noninvasive imaging has gained considerable momentum in providing accurate assessment of the entire RV-pulmonary axis. In this state-of-the-art review, we will discuss the most recent developments in echocardiography, magnetic resonance imaging, and computed tomography in PH evaluation from pediatric to adult population.

Abstract
Background Presentation of life-threatening arrhythmias concomitantly with a new-onset non-ischaemic cardiomyopathy raises concern for an inflammatory cardiomyopathy such as cardiac sarcoidosis or cardiac manifestations of connective tissue disease. Comprehensive workup for specific aetiologies may be unrevealing except for signs of myocardial inflammation identified on cardiac positron emission tomography (PET). Here, we present five cases of such subjects and their clinical course. Case summary We collected clinical, imaging, pathological, and follow-up data of five subjects presenting with arrhythmias and unexplained new-onset cardiomyopathy. Mean age was 56.2 ± 5.8 years. Three subjects presented with ventricular tachycardia and two with atrial arrhythmias. Echocardiography showed a mean left ventricular ejection fraction of 37 ± 9%. Significant coronary artery disease was ruled out in all cases as the cause of the cardiomyopathy. All patients underwent cardiac magnetic resonance imaging (MRI) and PET scan at presentation and follow-up. In all patients, cardiac MRI revealed hyperenhancement in epicardial and mid-myocardial pattern in a non-coronary distribution, while PET scan revealed fluorodeoxyglucose (FDG) mismatch defects in multiple foci in a non-coronary distribution. Right ventricular biopsy was obtained in all patients and revealed interstitial fibrosis and cardiomyocyte hypertrophy. On median follow-up of 210 days, all subjects had improvement in both heart failure symptoms and arrhythmias and repeat PET in four out of five patients showed decreased inflammation. Discussion A high level of suspicion for inflammatory cardiomyopathy is needed in patients presenting with new unexplained cardiomyopathy and arrhythmias. A cardiac FDG-PET should be considered for diagnosis if cardiac inflammation is in the differential. This can inform further decisions regarding targeted immunomodulation therapy that may be helpful in this cohort.

Abstract
This study validated a novel virtual echocardiography screening tool (VEST), which utilized routinely reported echocardiography parameters to predict hemodynamic profiles in pulmonary hypertension (PH) and identify PH due to pulmonary vascular disease (PHPVD). Direct echocardiography imaging review has been shown to predict hemodynamic profiles in PH; however, routine use often overemphasizes Doppler-estimated pulmonary artery systolic pressure (PASPDE), which lacks discriminatory power among hemodynamically varied PH subgroups. In patients with PH of varying subtypes at a tertiary referral center, reported echocardiographic findings needed for VEST, including left atrial size, E:e' and systolic interventricular septal flattening, were obtained. Receiver operating characteristic analyses assessed the predictive performance of VEST vs. PASPDE in identifying PHPVD, which was later confirmed by right heart catheterization. VEST demonstrated far superior discriminatory power than PASPDE in identifying PHPVD. A positive score was 80.0% sensitive and 75.6% specific for PHPVD with an area under the curve of 0.81. PASPDE exhibited poorer discriminatory power with an area under the curve of 0.56. VEST's strong discriminatory ability remained unchanged when validated in a second cohort from another tertiary center. We demonstrated that this novel VEST using three routine parameters that can be easily extracted from standard echocardiographic reports can successfully capture PH patients with a high likelihood of PHPVD. During the Covid-19 pandemic, when right heart catheterization and timely access to experts at accredited PH centers may have limited widespread availability, this may assist physicians to rapidly and remotely evaluate PH patients to ensure timely and appropriate care.

Abstract
BACKGROUND Tumor embolism is a rare neoplastic complication that occurs when there is intravenous invasion by a benign or malignant tumor. We present the case of an asymptomatic patient with an incidentally discovered leiomyosarcoma tumor emboli, which was initially misdiagnosed as "thrombus in transit." CASE REPORT The patient was a 58-year-old woman who was incidentally found on echocardiogram to have a large tubular mass within the inferior vena cava and right atrium. Although initially characterized as "thrombus in transit", this mobile right atrial mass was present without clinical, echocardiographic, or radiographic evidence of pulmonary embolism or increased pulmonary arterial impedance. Given that a thrombus in transit is nearly always associated with submassive or massive pulmonary emboli and their attendant right heart sequelae, these pertinent negative findings led us to seek an alternative diagnosis. After a trial of conservative management with anticoagulation and attempted removal of the mass with the AngioVac system, the patient ultimately underwent median sternotomy and surgical embolectomy on cardiopulmonary bypass to remove the mass, which was later identified on pathology as a leiomyosarcoma. CONCLUSIONS With rare exceptions, "thrombus in transit" is accompanied by large pulmonary emboli and the presence of increased pulmonary artery pressure and right heart strain. The absence of clinical, echocardiographic, or radiographic evidence of these hemodynamic sequelae should raise suspicion for an alternative diagnosis. Tumor embolism should be considered in the differential diagnosis of any patient with a history of malignancy who presents with evidence of intracardiac mass or embolism.

Abstract
Uterine fibroids have been described as an associate to acute venous thromboembolism (VTE), with case reports showing an association between large uterine fibroids, acute deep venous thrombosis (DVT), and acute pulmonary embolism (PE). However, there is little known about the association or causation between uterine fibroids, chronic thromboembolic disease (CTED), and chronic thromboembolic pulmonary hypertension (CTEPH). We report on six women with uterine fibroids and CTEPH, as well as one woman with CTED, all of whom presented with exertional dyspnea, lower extremity swelling, and in the cases of CTEPH, clinical, echocardiographic, and hemodynamic evidence of pulmonary hypertension and right heart failure. Compression of the pelvic veins by fibroids was directly observed with invasive venography or contrast-enhanced computed tomography in five cases. All seven women underwent pulmonary thromboendarterectomy (PTE) followed by marked improvement in functional, clinical, and hemodynamic status.

Right ventricular base/apex ratio in the assessment of pediatric pulmonary arterial hypertension: Results from the European Pediatric Pulmonary Vascular Disease Network. Clin Cardiol 2018; 41:1144-1149. [PMID: 29896859 DOI: 10.1002/clc.22994] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 05/18/2018] [Accepted: 06/10/2018] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Echocardiographic determination of RV end-systolic base/apex (RVES b/a) ratio was proposed to be of clinical value for assessment of pulmonary arterial hypertension (PAH) in adults. HYPOTHESIS We hypothesized that the RVES b/a ratio will be affected in children with PAH and aimed to correlate RVES b/a ratio with conventionally used echocardiographic and hemodynamic variables, and with New York Heart Association (NYHA) functional class. METHODS First we determined normal pediatric values for RVES b/a ratio in 157 healthy children (68 males; age range, 0.5-17.7 years). We then conducted an echocardiographic study in 51 children with PAH (29 males; age range, 0.3-17.8 years). RESULTS RVES b/a ratio was lower compared with age- and sex-matched healthy controls (P < 0.001). In children with PAH, RVES b/a ratio decreased with worsening NYHA class. RVES b/a ratio inversely correlated with RV/LV end-systolic diameter ratio (ρ = -0.450, P = 0.001) but did not correlate with RV systolic function parameters (eg, tricuspid annular plane systolic excursion) and correlated with cardiac catheterization-determined pulmonary vascular resistance index (ρ = -0.571, P < 0.001). ROC analysis unraveled excellent performance of RVES b/a ratio to detect PAH in children (AUC: 0.95, 95% CI: 0.89-1.00, P < 0.001). CONCLUSIONS The RVES b/a ratio decreased in children with PAH compared with age- and sex-matched healthy subjects. The RVES b/a ratio inversely correlated with both echocardiographic and hemodynamic indicators of increased RV pressure afterload and with NYHA class, suggesting that RVES b/a ratio reflects disease severity in PAH children.
