Evaluation of intraventricular flow by multimodality imaging: a review and meta-analysis.
Background: The aim of this systematic review was to evaluate current inter-modality agreement of noninvasive clinical intraventricular flow (IVF) assessment with 3 emerging imaging modalities: echocardiographic particle image velocimetry (EPIV), vector flow mapping (VFM), and 4-dimensional flow cardiovascular magnetic resonance imaging (4D flow CMR).
Methods: We performed a systematic literature review in the databases EMBASE, Medline OVID and Cochrane Central for identification of studies evaluating left ventricular (LV) flow patterns using one of these flow visualization modalities. Of the 2224 initially retrieved records, 10 EPIV, 23 VFM, and 25 4D flow CMR studies were included in the final analysis.
Results: Vortex parameters were more extensively studied with EPIV, while LV energetics and LV transport mechanics were mainly studied with 4D flow CMR, and LV energy loss and vortex circulation were implemented by VFM studies. Pooled normative values are provided for these parameters. The meta- analysis for the values of two vortex morphology parameters, vortex length and vortex depth, failed to reveal a significant change between heart failure patients and healthy controls.
Conclusion: Agreement between the different modalities studying intraventricular flow is low and different methods of measurement and reporting were used among studies. A multimodality framework with a standardized set of flow parameters is necessary for implementation of noninvasive flow visualization in daily clinical practice. The full potential of noninvasive flow visualization in addition to diagnostics could also include guiding medical or interventional treatment.
期刊介绍：
Cardiovascular Ultrasound is an online journal, publishing peer-reviewed: original research; authoritative reviews; case reports on challenging and/or unusual diagnostic aspects; and expert opinions on new techniques and technologies. We are particularly interested in articles that include relevant images or video files, which provide an additional dimension to published articles and enhance understanding.
As an open access journal, Cardiovascular Ultrasound ensures high visibility for authors in addition to providing an up-to-date and freely available resource for the community. The journal welcomes discussion, and provides a forum for publishing opinion and debate ranging from biology to engineering to clinical echocardiography, with both speed and versatility.
