Echocardiographic and lung ultrasound characteristics in ambulatory patients with dyspnea or prior heart failure.
2013
Purpose Lung ultrasound (LUS) represents a novel, noninvasive method in the assessment of extravascular lung water. We investigated the utility of LUS in ambulatory subjects with dyspnea or prior heart failure (HF). Methods We studied 81 ambulatory subjects with HF history or dyspnea who underwent transthoracic echocardiography (TTE) with LUS of 8 zones. Subjects with heart transplantation or pulmonary conditions known to interfere with LUS were excluded. A reviewer blinded to the clinical data performed echocardiographic measurements and quantified B-lines (reverberation artifacts arising from the pleural line). Results Of 81 subjects, 74 (91%) (median age 66 years, 39% men, median left ve…
Beurteilung des Flüssigkeitsgehaltes der Lunge anhand des Thorax-Röntgenbildes: Vergleich der Messung des extravaskulären Lungenwassers und der Ergeb…

Extravascular lung water (EVLW) was determined with the thermal-dye double-indicator method (119 individual measurements) in 23 patients in an intensive-care unit, and the results were compared with estimates made from largely standardized portable chest X-ray films, using the staging method of Sibbald as well as that of Halperin. There was a significant correlation with the measured EVLW for both methods. Radiologically "normal" films corresponded to a mean EVLW value of 8.4 ml/kg body-weight. Radiologically judged adjacent stages did not in all cases compare with corresponding measured EVLW values. But when EVLW values were clearly abnormal, the X-ray films always demonstrated massive int…
B-Lines for the assessment of extravascular lung water: Just focused or semi-quantitative?
2020
BACKGROUND B-lines as typical artefacts of lung ultrasound are considered as surrogate measurement for extravascular lung water. However, B-lines develop in the sub-pleural space and do not allow assessment of the whole lung. Here, we present data from the first observational multi-centre study focusing on the correlation between a B-lines score and extravascular lung water in critically ill patients suffering from a variety of diseases. PATIENTS AND METHODS In 184 adult patients, 443 measurements were obtained. B-lines were counted and expressed in a score which was compared to extravascular lung water, measured by single-indicator transpulmonary thermodilution. Appropriate correlation coe…
The new clinical standard of integrated quadruple stress echocardiography with ABCD protocol
2018
Abstract Background The detection of regional wall motion abnormalities is the cornerstone of stress echocardiography. Today, stress echo shows increasing trends of utilization due to growing concerns for radiation risk, higher cost and stronger environmental impact of competing techniques. However, it has also limitations: underused ability to identify factors of clinical vulnerability outside coronary artery stenosis; operator-dependence; low positivity rate in contemporary populations; intermediate risk associated with a negative test; limited value of wall motion beyond coronary artery disease. Nevertheless, stress echo has potential to adapt to a changing environment and overcome its c…
