Coronary Slow Flow in a Patient with Myocarditis
2016
A young patient presented with dyspnea and high troponin. Coronary angiography excluded a diagnosis of CAD, but was diagnostic for the presence of coronary slow flow. Thermodilution showed increased resting resistances in the presence of hypernormal CFR.
Multispectral Photophletysmography for Evaluation of Cutaneous Flowmotions
2021
Human skin may reflect health conditions. Important and possibly diagnostically potent components of microcirculation are slow flow oscillations-flowmotions, however there is a lack of studies in this field. The present pilot study was devoted to evaluation of multispectral imaging photoplethysmography in determination of different components of flowmotions. Eight subjects were enrolled for the study. During resting conditions video was captured from dorsal aspect of hand at seven different wavelength and flowmotion analysis performed. Results indicate that at the resting conditions neurogenic component along with endothelial are dominant regardless of wavelength, while myogenic has the low…
Quantitative in vivo microdialysis in pharmacokinetic studies: some reminders.
2005
This paper reviews the empirical methods of quantitative microdialysis that have been used to interpret the results obtained from pharmacokinetic studies. The concept of extraction efficiency or recovery and the properties of recovery in vivo (variation with flow rate, time dependency and influence of the mode of administration) are considered. The most frequently used methods for determining recovery in vivo are described and evaluated in the light of recent theoretical studies. Specifically, we review the variation of flow rate method, the very slow flow method, the no net flux method and the delivery and retrodialysis methods. Special emphasis is placed on the description of each method,…
A Complex Combination of Microvascular and Macrovascular Diseases
2016
When FFR is larger than 0.80, a PCI is not justified. Transient microvascular dysfunction may, however, be associated with impaired hyperemia and falsely negative FFR. This case also emphasizes the dynamic nature of microvascular disease, and provides an example of both “typical” syndrome X and “less conventional” syndrome slow flow associated with increased peripheral resistances (see Chap. 35).
