A case of pulmonary edema: The critical role of lung-heart integrated ultrasound examination.

Cardiogenic pulmonary edema is a common presentation of acute heart failure normally treated with continuous positive airway pressure (CPAP), diuretics and nitrates. This therapy is contraindicated in case of cardiac tamponade. We describe a case of pulmonary edema due to cardiac tamponade in which integrated lung-heart ultrasound examination allowed prompt diagnosis and pericardiocentesis before administration of CPAP thus avoiding circulatory collapse

Diagnostic performance of multi-organ ultrasound with pocket-sized device in the management of acute dyspnea

The availability of ultra-miniaturized pocket ultrasound devices (PUD) adds diagnostic power to the clinical examination. Information on accuracy of ultrasound with handheld units in immediate differential diagnosis in emergency department (ED) is poor. The aim of this study is to test the usefulness and accuracy of lung ultrasound (LUS) alone or combined with ultrasound of the heart and inferior vena cava (IVC) using a PUD for the differential diagnosis of acute dyspnea (AD)

Diagnostic accuracy of inferior vena cava evaluation in the diagnosis of acute heart failure among dyspneic patients.

Acute dyspnea is one of the main reasons for admission to the Emergency Department (ED). A rapid and accurate diagnosis can be lifesaving for these patients. Particularly, it is important to differentiate between dyspnea due to acute heart failure (AHF) and dyspnea of pulmonary origin. The aim of this study is to evaluate the real accuracy of the evaluation of diameter and collapsibility of IVC for the diagnosis of AHF among dyspneic patients. We analyzed 155 patients admitted for acute dyspnea to the ED of "Maurizio Bufalini" hospital in Cesena (Italy) and "Antonio Cardarelli" hospital in Naples (Italy) from November 2014 to April 2017. All patients underwent ultrasound of inferior vena cava (IVC) examination with a hand-held device in addition to the traditional pathway. Patients were classified into AHF group or non-AHF group according to the current guidelines. The final diagnosis was AHF in 64 patients and dyspnea of non-cardiac origin in 91 patients. Sensibility and specificity of IVC hypo-collapsibility was 75.81% (95% CI 63.26% to 85.78%) and 67.74% (95% CI 57.25% to 77.07%) for the diagnosis of AHF. Sensibility and specificity of IVC dilatation was 69.35% (95% CI 56.35% to 80.44%) and 74.19% (95%CI 64.08% to 82.71%) for the diagnosis of AHF. AUC was 0.718 (0.635-0.801) for IVC hypo-collapsibility, 0.718 (0.634-0.802) for IVC dilatation. Our study demonstrated that the sonographic assessment of IVC diameter and collapsibility is suboptimal to differentiate acute dyspnea due to AHF or other causes in the emergency setting

Interstitial syndrome-lung ultrasound B lines: a potential marker for pulmonary metastases? A case series

Four patients presented to the Emergency Department with dyspnea and they underwent point-of-care ultrasound. Lung ultrasound showed a diffuse bilateral B-profile pattern-interstitial syndrome, they underwent contrast-enhanced computed tomography scan of thorax that showed multiple bilateral lung metastases. The detection, in a dyspneic patient, of a diffuse Bprofile pattern not attributable to traditional interstitial syndrome conditions (pulmonary fibrosis, acute respiratory distress syndrome, acute pulmonary edema, interstitial pneumonia) could be indicative of multiple pulmonary metastases

Continuous positive airway pressure therapy in the management of hypercapnic cardiogenic pulmonary edema.

Continuous positive airway pressure (CPAP) therapy or non-invasive ventilation (NIV) represent the first line therapy for acute cardiogenic pulmonary edema (CPE) together with medical therapy. CPAP benefits in acute CPE with normo-hypocapnia are known, but it is not clear whether the use of CPAP is safe in the hypercapnic patients. The aim of this study is to evaluate CPAP efficacy in the treatment of hypercapnic CPE. We enrolled 9 patients admitted to the emergency room with diagnosis of acute CPE based on history, clinical examination, arterial blood gas analysis (ABG) and lung-heart ultrasound examination. We selected patients with hypercapnia (pCO2 >50 mmHg) and bicarbonate levels <30 mEq/L. All patients received medical therapy with furosemide and nitrates and helmet CPAP therapy. All patients received a second and a third ABG, respectively at 30 and 60 min. Primary end-points of the study were respiratory distress resolution, pCO2 reduction, pH improvement, lactates normalization and the no need for non-invasive ventilation or endo-tracheal intubation. All patients showed resolution of respiratory distress with CPAP weaning and shift to Venturi mask with no need for NIV or endo-tracheal intubation. Serial ABG tests showed clear reduction in CO2 levels with improvement of pH and progressive lactate reduction. CPAP therapy can be effective in the treatment of hypercapnic CPE as long as the patients have no signs of chronic hypercapnia on ABG and as long as the diagnosis of heart failure is supported by bedside lung-heart ultrasound examination

Acute dyspnea in Emergency Department: point of care ultrasound in the diagnosis of atrial sarcoma

We describe a rare case of a 65-year-old patient presented to Emergency Department for acute dyspnea. Traditional diagnostic work-up was done and the emergency physician promptly performed a bedside point-of-care ultrasound. A giant mass in the left atrium was detected with impairing of mitral valve function. The patient was then sent to cardiac surgery department with a final diagnosis of high-grade cardiac sarcoma
