The mortality benefit of PAH-specific therapy for patients with pulmonary hypertension (PH) associated with lung disease is not clear. Our aim was to determine whether pulmonary arterial hypertension (PAH)-specific therapy is associated with reduced mortality among all patients with PH associated with lung disease and in patients with chronic lung disease and severe PH. This was a retrospective cohort study of patients at our institution with chronic lung disease and PH. Survival analysis was performed by comparing patients who received PAH-specific therapy with patients who did not receive pulmonary vasodilators in the entire cohort and in a subgroup of patients with severe PH defined as PVR > 5 WU. We identified 783 patients with chronic lung disease and PH; 246 patients met the new criteria for severe PH. In the entire cohort, a similar survival probability was seen between the treated and untreated PH groups (logrank p = 0.67). In the severe PH subgroup, patients treated with PAH-specific therapy had increased survival probability (logrank p = 0.03). PAH-specific therapy was independently and significantly associated with decreased mortality in severe PH (HR 0.31, 95% CI 0.11–0.88, p = 0.03). PAH-specific therapy may confer a mortality benefit in patients with chronic lung disease and severe PH, which is now defined as PVR > 5 WU, similarly to those with pulmonary arterial hypertension.

Abstract Pulmonary embolism (PE) is the third leading cause of cardiovascular death in the United States. Black Americans have higher incidence, greater clot severity, and worse outcomes than White Americans. This disparity is not fully understood, especially in the context of the advent of PE response teams (PERT), which aim to standardize PE‐related care. This retrospective single‐center cohort study compared 294 Black and 131 White patients from our institution's PERT database. Primary objectives included severity and in‐hospital management. Secondary outcomes included length of stay, 30‐day readmission, 30‐day mortality, and outpatient follow‐up. Clot (p = 0.42), acute treatment (p = 0.28), 30‐day mortality (p = 0.77), 30‐day readmission (p = 0.50), and outpatient follow‐up (p = 0.98) were similar between races. Black patients had a lower mean household income ($35,383, SD 20,596) than White patients ($63,396, SD 32,987) (p

Introduction: Right ventricular dysfunction (RVD) is a key component in the process of risk stratification in patients with acute pulmonary embolism (PE). Echocardiography remains the gold standard for RVD assessment, however, measures of RVD may be seen on CTPA imaging, including increased pulmonary artery diameter (PAD). The aim of our study was to evaluate the association between PAD and echocardiographic parameters of RVD in patients with acute PE. Methods: Retrospective analysis of patients diagnosed with acute PE was conducted at large academic center with an established pulmonary embolism response team (PERT). Patients with available clinical, imaging, and echocardiographic data were included. PAD was compared to echocardiographic markers of RVD. Statistical analysis was performed using the Student's t test, Chi-square test, or one-way analysis of variance (ANOVA); P < 0.05 was considered statistically significant. Results: 270 patients with acute PE were identified. Patients with a PAD >30 mm measured on CTPA had higher rates of RV dilation (73.1% vs 48.7%, P < 0.005), RV systolic dysfunction (65.4% vs 43.7%, P < 0.005), and RVSP >30 mmHg (90.2% vs 68%, P = 0.004), but not TAPSE ≤1.6 cm (39.1% vs 26.1%, P = 0.086). A weak increasing linear relationship between PAD and RVSP was noted (r = 0.379, P = 0.001). Conclusions: Increased PAD in patients with acute PE was significantly associated with echocardiographic markers of RVD. Increased PAD on CTPA in acute PE can serve as a rapid prognostic tool and assist with PE risk stratification at the time of diagnosis, allowing rapid mobilization of a PERT team and appropriate resource utilization.

Abstract Rosai–Dorfman disease (RDD) is a rare form of non‐Langerhans histiocytosis. It is often idiopathic in etiology, but has been associated with viral, autoimmune, and malignant disease. Adequate diagnosis of RDD requires a combination of clinical symptoms, radiography, and histology. Most commonly, patients with RDD present with cervical lymphadenopathy. We describe a case of a young female who was initially thought to have a pulmonary embolism at the time of a COVID‐19 infection but was noted to have a rare occurrence of RDD presenting as a pulmonary artery mass upon further evaluation of radiology and histology. Though RDD is frequently benign, extranodal involvement can progress to end organ damage and must be recognized appropriately.

BackgroundInterhospital transfer (IHT) of patients with acute life-threatening pulmonary embolism (PE) is necessary to facilitate specialized care and access to advanced therapies. Our goal was to understand what barriers and facilitators may exist during this transfer process from the perspective of both receiving and referring physicians.MethodsThis qualitative descriptive study explored physician experience taking care of patients with life threatening PE. Subject matter expert physicians across several different specialties from academic and community United States hospitals participated in qualitative semi-structured interviews. Interview transcripts were subsequently analyzed using inductive qualitative description approach.ResultsFour major themes were identified as barriers that impede IHT among patients with life threatening PE. Inefficient communication which mainly pertained to difficulty when multiple points of contact were required to complete a transfer. Subjectivity in the indication for transfer which highlighted the importance of physicians understanding how to use standardized risk stratification tools and to properly triage these patients. Delays in data acquisition were identified in regards to both obtaining clinical information and imaging in a timely fashion. Operation barriers which included difficulty finding available beds for transfer and poor weather conditions inhibiting transportation. In contrast, two main facilitators to transfer were identified: good communication and reliance on colleagues and dedicated team for transferring and treating PE patients.ConclusionThe most prominent themes identified as barriers to IHT for patients with acute life-threatening PE were: (1) inefficient communication, (2) subjectivity in the indication for transfer, (3) delays in data acquisition (imaging or clinical), and (4) operational barriers. Themes identified as facilitators that enable the transfer of patients were: (1) good communication and (2) a dedicated transfer team. The themes presented in our study are useful in identifying opportunities to optimize the IHT of patients with acute PE and improve patient care. These opportunities include instituting educational programs, streamlining the transfer process, and formulating a consensus statement to serve as a guideline regarding IHT of patients with acute PE.

Atrial myxomas, though the most common primary cardiac neoplasm, remain a rare disease occurring in about 0.03% of the population. While clinically benign, they are considered functionally malignant as they can cause life-threatening embolic events. Here we present a patient with a high-risk intermediate pulmonary embolism where bedside ultrasound revealed significant right ventricular dysfunction with an associated large left atrial mass. These findings combined with the patient's instability allowed her to be rushed to surgery for definitive treatment.

Objective Pulmonary infarction is a common clinical and radiographic finding in acute pulmonary embolism (PE), yet the clinical relevance and prognostic significance of pulmonary infarction remain unclear. The study aims to investigate the clinical features, radiographic characteristics, impact of reperfusion therapy and outcomes of patients with pulmonary infarction.Design, setting and participants A retrospective cohort study of 496 adult patients (≥18 years of age) diagnosed with PE who were evaluated by the PE response team at a tertiary academic referral centre in the USA. We collected baseline characteristics, laboratory, radiographic and outcome data. Statistical analysis was performed by Student’s t-test, Mann-Whitney U test, Fischer’s exact or χ2 test where appropriate. Multivariate logistic regression was used to evaluate potential risk factors for pulmonary infarction.Results We identified 143 (29%) cases of pulmonary infarction in 496 patients with PE. Patients with infarction were significantly younger (52±15.9 vs 61±16.6 years, p

Background The impact of pulmonary embolism response teams (PERTs) on treatment choice and outcomes of patients with acute pulmonary embolism (PE) is still uncertain. Objective To determine the effect of PERTs in the management and outcomes of patients with PE. Methods PubMed, Embase, Web of Science, CINAHL, WorldWideScience and MedRxiv were searched for original articles reporting PERT patient outcomes from 2009. Data were analysed using a random effects model. Results 16 studies comprising 3827 PERT patients and 3967 controls met inclusion criteria. The PERT group had more patients with intermediate and high-risk PE (66.2%) compared to the control group (48.5%). Meta-analysis demonstrated an increased risk of catheter-directed interventions, systemic thrombolysis and surgical embolectomy (odds ratio (OR) 2.10, 95% confidence interval (CI) 1.74–2.53; p

Hemostatic derangement is a hallmark in severe COVID-19. Markedly elevation of D-dimer and fibrinogen degradation product levels were observed in patients with severe COVID-19 higher and 71.4% of nonsurvivors met the International Society of Thrombosis and Haemostasis criteria of disseminated intravascular coagulation (DIC). Although the clinical and epidemiological features of COVID-19 have been well-described, the underlying mechanism influencing disease severity remains to be elucidated. Herein, the aim of this review article is to evaluate hemostasis in the pathogenesis of COVID-19 and its role in the management of this unprecedented pandemic.

COVID-19 pneumonia is a serious health issue in the current pandemic caused by SARS-CoV-2. PCR testing is limited due to a number of factors and imaging has role in decision-making for many of these patients. We present computed tomography chest images of patients hospitalized with suspicion of COVID-19 pneumonia and point out the common and uncommon features on imaging to assist management of these patients.

We present the characteristics and outcomes of the first 2 cases of catheter-directed thrombolysis performed in patients presenting with coronavirus disease-2019 (COVID-19)-related iliocaval thrombosis. (Level of Difficulty: Beginner.)

Abstract Pulmonary embolism (PE) response teams are the standard of care for the management of acute PE. The complications of PE extend far beyond the initial hospitalization period. In this study, we examined the role and potential benefits of dedicated pulmonary follow‐up after hospital discharge for patients with PE.

BackgroundThe use of high-flow nasal therapy (HFNT) to treat COVID-19 pneumonia has been greatly debated around the world due to concerns about increased health care worker transmission and delays in invasive mechanical ventilation (IMV). Herein, we analyzed the utility of the noninvasive ROX (ratio of oxygen saturation) index to predict the need for and timing of IMV. ObjectiveThis study aimed to assess whether the ROX index can be a useful score to predict intubation and IMV in patients receiving HFNT as treatment for COVID-19–related hypoxemic respiratory failure. MethodsThis is a retrospective cohort analysis of 129 consecutive patients with COVID-19 admitted to Temple University Hospital in Philadelphia, PA, from March 10, 2020, to May 17, 2020. This is a single-center study conducted in designated COVID-19 units (intensive care unit and other wards) at Temple University Hospital. Patients with moderate and severe hypoxemic respiratory failure treated with HFNT were included in the study. HFNT patients were divided into two groups: HFNT only and intubation (ie, patients who progressed from HFNT to IMV). The primary outcome was the value of the ROX index in predicting the need for IMV. Secondary outcomes were mortality, rate of intubation, length of stay, and rate of nosocomial infections in a cohort treated initially with HFNT. ResultsOf the 837 patients with COVID-19, 129 met the inclusion criteria. The mean age was 60.8 (SD 13.6) years, mean BMI was 32.6 (SD 8) kg/m², 58 (45%) were female, 72 (55.8%) were African American, 40 (31%) were Hispanic, and 48 (37.2%) were nonsmokers. The mean time to intubation was 2.5 (SD 3.3) days. An ROX index value of less than 5 at HFNT initiation was suggestive of progression to IMV (odds ratio [OR] 2.137, P=.052). Any further decrease in ROX index value after HFNT initiation was predictive of intubation (OR 14.67, P

Introduction Acute pulmonary embolism (PE) remains a common cause for morbidity and mortality in patients over 65 years. Given the increased risk of bleeding in the elderly population with the use of systemic thrombolysis, catheter-directed therapy (CDT) is being increasingly used for the treatment of submassive PE. Nevertheless, the safety of CDT in the elderly population is not well studied. We, therefore, aimed to evaluate the safety of CDT in our elderly patients.Methods We conducted a retrospective observational study of consecutive patients aged >65 years with a diagnosis of PE from our Pulmonary Embolism Response Team database. We compared the treatment outcomes of CDT versus anticoagulation (AC) in elderly. Propensity score matching was used to construct two matched cohorts for final outcomes analysis.Results Of 346 patients with acute PE, 138 were >65 years, and of these, 18 were treated with CDT. Unmatched comparison between CDT and AC cohorts demonstrated similar in-hospital mortality (11.1% vs 5.6%, p=0.37) and length of stay (LOS) (3.81 vs 5.02 days, p=0.5395), respectively. The results from the propensity-matched cohort mirrored results of the unmatched cohort with no significant difference between CDT and AC in-hospital mortality (11.8% vs 5.9%, p=0.545) or median LOS (3.76 vs 4.21 days, p=0.77), respectively.Conclusion In this observational study using propensity score-matched analysis, we found that patients >65 years who were treated with CDT for management of acute PE had similar mortality and LOS compared with those treated with AC. Further studies are required to confirm these findings.

Conclusion HFNT use is associated with a reduction in the rate of invasive mechanical ventilation and overall mortality in patients with COVID-19 infection.

Background: The aging of the US population has been associated with an increase in intensive care unit (ICU) utilization and correspondingly, invasive mechanical ventilation (IMV) among the oldest-old (age ≥80 years). While previous studies have examined ICU and IMV outcomes in the elderly, very few have focused on patient-centered outcomes, specifically home return, in the oldest-old. We investigated the rate of immediate home return following IMV in the medical ICU in previously home-dwelling oldest-old patients relative to that of a comparison group of 50–70-year olds. Methods: Data were extracted retrospectively from patient records at Elmhurst Hospital Center in Elmhurst, NY, USA, encompassing the period from January 2009 to May 2014 and Jacobi Medical Center in the Bronx, NY, USA, from January 2010 to March 2014. Medical ICU admissions within those date ranges were screened for possible inclusion into one of two study groups based on age: ≥80 years old and 50–70 years old. The primary end point was hospital discharge: home return versus no home return (death or nonhome discharge). Cox proportional hazards' regression models were used to estimate crude and multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for failure to return home. Results: A total of 375 patients were included in the analysis: 279 (74%) patients aged 50–70 years and 96 (26%) patients aged ≥80 years. Compared to 50–70-year olds, being ≥80 years old was associated with a nearly two-fold greater risk of no home return: adjusted HR: 1.96; 95% CI 1.43–2.67. The oldest-old was at significantly increased risk of both being discharged to a skilled nursing facility or subacute rehabilitation (adjusted HR: 2.19; 95% CI 1.33–3.59) as well as of dying in the hospital (adjusted HR: 1.81; 95% CI 1.21–2.71). Conclusion: Previously home-dwelling oldest-old are at significantly increased risk of failing to return home immediately following medical ICU admission with IMV as compared to patients aged 50–70 years. These results can help medical ICU staff establish appropriate expectations when addressing the families of their oldest patients. Further studies are needed to evaluate the potential for delayed home return among the oldest old and to assess the ability of frailty indices to predict home return within this ICU population.

Invasive aspergillosis generally occurs during the first 1–6 months after heart transplantation. It has been rarely seen in the first 2 weeks postcardiac transplant. We herein describe a unique case of invasive pulmonary aspergillosis (IPA) diagnosed on day 9 postorthotopic heart transplantation. The known risk factors for IPA in cardiac transplant recipients were not identified in our case. The organ recipients from the same donor did not report Aspergillus infection. Hospital environmental samplings failed to demonstrate Aspergillus spores in the patient's room and his adjacent rooms. A diagnosis of early-onset de novo IPA was made. The patient initially received combined antifungal therapy (voriconazole plus micafungin), followed by voriconazole maintenance monotherapy with favorable clinical outcome.

We present a case of a glomus tumor of trachea in an elderly female who presented with a mass originating from the posterior trachea. She underwent rigid bronchoscopy with tumor debulking combined with laser therapy. Frozen section initially suggested carcinoid tumor but later turned out to be a glomus tumor. She improved with additional laser therapy. We present her clinical course and a literature review on glomus tumor.

Pulmonary embolism (PE) is a life-threatening condition and a leading cause of morbidity and mortality. There have been many advances in the field of PE in the last few years, requiring a careful assessment of their impact on patient care. However, variations in recommendations by different clinical guidelines, as well as lack of robust clinical trials, make clinical decisions challenging. The Pulmonary Embolism Response Team Consortium is an international association created to advance the diagnosis, treatment, and outcomes of patients with PE. In this consensus practice document, we provide a comprehensive review of the diagnosis, treatment, and follow-up of acute PE, including both clinical data and consensus opinion to provide guidance for clinicians caring for these patients.

We represent a fatal case of atrio esophageal fistula that presented as upper GI bleed. The case was complicated by rapidly progressing multi organ dysfunction syndrome and eventual death. This was an iatrogenic complication of an elective procedure.

Carcinoid tumors rarely originate in the urogenital system. We represent a unique case of primary renal carcinoid tumor which was initially diagnosed as renal cell cancer and 10 years later correctly diagnosed as metastatic renal carcinoid.

Choriocarcinoma is part of the spectrum of gestational trophoblastic disease that occurs in women of reproductive age. Although the most common metastatic site of choriocarcinoma is the lung, primary pulmonary choriocarcinoma is rare. To diagnose primary pulmonary choriocarcinoma, the patient should have no previous gynecologic malignancy, have elevated human chorionic gonadotropin, and have pathological confirmation of the disease excluding gonadal primary site of the tumor. Due to the paucity of data, there are no guidelines for treatment. Prognosis of this malignancy is extremely poor. We report a rare case of metastatic primary lung choriocarcinoma in a 69-year-old postmenopausal woman who was treated with combination of surgery, chemotherapy, and radiation. The patient had a good outcome and is doing well after 1-year follow-up.

We represent an unfortunate case of postinfluenza streptococcal endocarditis in a 34-year-old healthy male. He presented with hypoxic respiratory failure and was found to have mitral and aortic valve vegetation. Hospital course was complicated by the presence of an aortoatrial fistula from an aortic root abscess, persistent septic shock, and multiorgan failure.

We present a case of tuberculous (TB) meningitis in nonimmunocompromised immigrant worker who initially presented with headache and later with generalized tonic clonic seizures and disseminated tuberculosis.

Background To evaluate the occurrence of malnutrition in pulmonary embolism (PE)-related hospitalisations and assess the impact of malnutrition on the outcomes of patients with PE.Methods A retrospective observational study using data extracted from the Nationwide Inpatient Sample from 2016 to 2018. Hospitalisations with a principal diagnosis of PE were obtained using International Classification of Diseases, Tenth Revision codes and divided into groups based on a secondary diagnosis of malnutrition.Results Of 563 135 PE hospitalisations, 30 495 (5.4%) had malnutrition. PE patients with malnutrition were older (mean age±SD, 69.1±14.5 vs 62.3±16.6, p
