Respiratory ventricular area changes measured with real-time cardiac magnetic resonance: A new, accurate, and reproducible approach for the diagnosis of pericardial constriction

摘要

Demonstration of pericardial pathology and/or constrictive physiology remains the basis for the diagnosis of pericardial constriction (PC). Cardiovascular magnetic resonance (CMR) is increasingly used to depict pericardial abnormalities [1-6]. Moreover, the Society of CMR endorses visual determination of abnormal respiratory septal motion characteristic of constrictive physiology on real-time cine imaging [7], and preliminary CMR studies have attempted to quantify this sign of increased ventricular interdependence [8,9] (Fig. 1). Our goal was to develop a simple, accurate, and reproducible method for the quantification of ventricular interdependence with free-breathing CMR for PC diagnosis.
