While in labor, a 37-year-old woman developed acute dyspnea, hypoxemia, and tachycardia. Transthoracic echocardiography demonstrated severe right ventricular dilation and dysfunction, raising the suspicion of acute pulmonary embolism. The patient indeed had bilateral pulmonary embolism, necessitating percutaneous thrombectomy. Her course was complicated by another saddle pulmonary embolus, heparin-induced thrombocytopenia, and COVID-19 infection. This clinical case illustrates the importance of prompt diagnosis of acute pulmonary embolism in a peripartum female patient, the multidisciplinary approach of management, and how to approach clinical complications such as heparin-induced thrombocytopenia. Furthermore, long-term management in acute pulmonary embolism is presented.

UNASSIGNED: The diagnosis and treatment of pulmonary embolism have multi-modal approach based on specificity, sensitivity, availability of the machine, and associated risks of imaging modalities.
UNASSIGNED: This review aimed to provide shreds of evidence that improve perioperative diagnosis and management of suspected pulmonary embolism.
UNASSIGNED: The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline 2020. After a clear criteria has been established an electronic searching database was conducted using PubMed, Google Scholar, Cochrane library, and Cumulative Index of Nursing and Allied Health Literature (CINAHL), with Key search terms included:(\'pulmonary embolism\' AND\' anesthesia management \', \'anticoagulation\' AND \'pulmonary embolism\', \'thrombolysis \'AND \'pulmonary embolism\', \'surgery\' AND\' pulmonary embolism\'), were used to draw the evidence.The quality of literatures were categorized based on WHO 2011 level of evidence and degree of recommendation, in addition, the study is registered with research registry unique identifying number (UIN) of reviewregistry1318.\" and has high quality based on AMSTAR2 assessment criteria.
UNASSIGNED: A totally of 27 articles were included [guidelines (n = 3), Cochrane (=5), systemic reviews (n = 7), meta-analyses (=2), RCT (n = 4), cohort studies (n = 3), and cross-sectional study (n = 3) and illegible articles identified from searches of the electronic databases were imported into the ENDNOTE software version X7.1 and duplicates were removed.
UNASSIGNED: Currently divergent and contradictory approaches are implemented in diagnosis and management for patients suspected of pulmonary embolism.
UNASSIGNED: All perioperative patients, especially trauma victims, prostate or orthopedic surgery, malignancy, immobility, and obesity; smokers; and oral contraceptive users, antipsychotic medications are at increased risk of venous thromboembolism and need special caution during surgery and anesthesia.

UNASSIGNED: The aim of the study was to investigate the potential of electrocardiogram (ECG)-gated computed tomography pulmonary angiography (CTPA) as a predictor of disease severity in patients with chronic thromboembolic pulmonary hypertension (CTEPH).
UNASSIGNED: Forty-five CTEPH patients with a mean age of 63.8 years±12.7 y (±standard deviation) who had undergone ECG-gated CTPA and right heart catheterization (RHC) were included in the study. Right ventricular to left ventricular volume ratio (RVV/LVV), diameter ratio on 4-chamber view (RVD4CH/LVD4CH), pulmonary trunk (PT) diameter, PT to aortic diameter ratio (PT/A), and septal angle were correlated to mean pulmonary artery pressure (mPAP). Moreover, RVV/LVV and RVD4CH/LVD4CH were adjusted to pulmonary diameter index (PADi) and PT/A index. Areas under the curve (AUC) for predicting mPAP above 40 mmHg, 35 mmHg, and 30 mmHg were calculated.
UNASSIGNED: RVD4CH/LVD4CH revealed the strongest correlation to mPAP before (r = 0.6507) and after (r = 0.7650; p < 0.0001) PT/A adjustment. The AUCs for predicting pH with mPAP over 40 mmHg and 30 mmHg were 0.9229 and 0.864, respectively. A cutoff value of 1.298 enabled prediction of pH with mPAP over 40 mmHg with a sensitivity, specificity, positive predictive, and negative predictive value of 80.00 %, 95.83 %, 88.46 %, and 94.12 %, respectively. Intra- and interobserver variability were excellent for all parameters.
UNASSIGNED: Combining different and easily evaluable ECG-gated CTPA parameters enables excellent prediction of pulmonary hemodynamics in CTEPH patients. Ventricular diameter ratio on 4-chamber view adjusted by the PT/A ratio yielded the best correlation to mPAP.

Due to the scarcity of data, Impella RP is not approved for acute right ventricular failure caused by massive pulmonary embolism. We describe here the successful use of Impella RP in acute right ventricular failure caused by massive pulmonary embolism to highlight its promising outcome in such an indication. (Level of Difficulty: Advanced.).

UNASSIGNED: Accurate diagnosis of pulmonary embolism (PE) using contrast enhanced MRA (CE-MRA) requires awareness of both the direct and indirect findings of PE.
UNASSIGNED: To evaluate reader agreement of the direct and indirect findings of PE on CE-MRA.
UNASSIGNED: We evaluated pulmonary artery diameter, right ventricle/left ventricle ratio, and clot/vessel lumen signal intensity ratio. Also, eight direct and eight indirect findings of PE were interpreted twice by two radiologists with different experience levels. The prevalence, and intra- and inter-reader agreement for the direct and indirect findings of PE were recorded. Statistical analysis of the measurements was assessed using intraclass correlation while Cohen\'s kappa test determined inter- and intra-reader agreement.
UNASSIGNED: We reviewed 66 positive CE-MRA exams, 10 of which cases were used for training. The largest PE for each of the remaining 56 cases (40 woman) were included in this analysis (38.9 ± 19.7 (mean age (years) ± S.D.)). The highest interobserver agreement for the direct findings were vessel cutoff (κ = 0.52, 95 % CI = (0.30, 0.74), p < .0001) and bright clot (κ = 0.51, 95 % CI = (0.26, 0.78), p = .0001). The highest interobserver agreement for the indirect findings were for atelectasis (κ = 0.67, 95 % CI = (0.49, 0.87), p < .0001), pleural effusions (κ = 0.56, 95 % CI = (0.32, 0.79), p = 0001) and blank slate sing (κ = 0.56, 95 % CI = (0.18, 0.94), p < .0001).
UNASSIGNED: The indirect findings of atelectasis and pleural effusion had better interobserver reproducibility than the direct findings of vessel cutoff and bright clot. The intraobserver reproducibility of the direct and indirect findings is dependent on experience level.
UNASSIGNED: Using contrast enhanced magnetic resonance angiography for the diagnosis of pulmonary embolism, the indirect findings of atelectasis and pleural effusion had better interobserver reproducibility than the direct findings of vessel cutoff and bright clot.

We describe the first case of HTLV associated bronchiolitis to be associated with HTLV-1c subtype infection. An Aboriginal man with HTLV-1 infection was repeatedly admitted to Alice Springs Hospital, central Australia, with hypercapnic respiratory failure from the age of 28 years. High resolution CT chest findings were consistent with bronchiolitis and large numbers of lymphocytes were found in bronchoalveolar lavage fluid (BALF). After extensive investigations failed to find a cause, he was tested for HTLV-1 and found to have a high HTLV-1c proviral load (6.8 %) in peripheral blood leukocytes and in BALF (4.7 %). The administration of systemic corticosteroids resulted in a rapid clinical response; however, he did not continue treatment after discharge and died due to respiratory failure in the community.

Known commonly as \"broken heart syndrome,\" takotsubo cardiomyopathy is a poorly understood heart condition that results in acute decompensation of cardiac function. We report a case of a 68-year-old female who developed acute shortness of breath status after chemotherapy and radiation treatment for Stage IV squamous-cell carcinoma. Computed tomography pulmonary angiogram (CTPA) revealed a single subsegmental pulmonary embolism, pulmonary edema, and left ventricular dilatation. Further evaluation revealed evidence of reversible cardiomyopathy with left ventricular apical ballooning, consistent with takotsubo cardiomyopathy. In reviewing the case, we cover the Mayo clinic criteria for diagnosis of takotsubo cardiomyopathy, and we consider pulmonary embolism as a precipitating factor.
