Pericardial Disease: Value of CT and MR Imaging | Radiology
2013年5月1日 · Pericardial enhancement reflects inflammation at histologic examination and is correlated with elevated inflammatory markers. Contrast-enhanced MR imaging, moreover, allows evaluation of the extent of inflammation into the surrounding fat and adjacent myocardial tissue.
Living Anatomy of the Pericardial Space: A Guide for Imaging and ...
2021年12月1日 · Living Anatomy of the Pericardial Space. Using injection of contrast into the pericardial space in a 38-year-old man with hypertrophic cardiomyopathy subsequent to an ablation, we performed image analyses using a commercially available workstation (Ziostation2 version 2.9.7.1, AMIN Co., Ziosoft).
Pericardial Anatomy, Interventions and Therapeutics: A …
2021年11月1日 · The pericardium is a dual-layered flask-shaped fibroserous sac enveloping the heart and proximal great vessels with a potential space created by the parietal and visceral layers (Figure 1). The outer fibrous layer is contiguous with the great vessels superiorly and the diaphragm inferiorly.
Evaluation of pericardial sinuses and recesses by radiographic contrast …
2018年10月1日 · Pericardial space could be opacified by injecting radiographic contrast agent though a 6-F pigtail catheter, which was placed in-situ to remove the rapidly accumulating blood in the pericardial space. Various pericardial sinuses and recesses could be delineated by injecting contrast in the space (Fig. 1, Video 1).
Cardiac tamponade after transmyocardial extravasation of contrast ...
Immediately after injection the operator noted that approximately 80 per cent of the contrast material had entered the pericardial sac rather than the left ventrk:le, and the patient complained of severe precordiaI pain. P, ecorded pressures showed a uormal left ven- …
Peripheral VA-ECMO and pericardial drainage connected to the …
2023年8月31日 · A carefully manoeuvred left ventriculogram showed contrast leakage from the inferior left ventricular wall into the pericardial cavity (Fig. 1D, Video S1). Clinical and contrast findings indicated a blowout rupture diagnosis; therefore, open chest surgery was scheduled with total cardiopulmonary bypass equipment.
Anatomy of Pericardial Recesses on Multidetector CT: - AJR
Axial contrast-enhanced multidetector CT scan delineates fluid in postcaval recess (long arrow) and posterior (arrowheads) to ascending aorta. Pericardial fluid also extends anterior (short arrows) to aorta (A) and pulmonary artery (PA) as well as in left pulmonic recess (asterisk) of transverse sinus. S = superior vena cava.
CT-Guided Pericardial Drainage: A Safe and Viable Alternative to ...
2022年8月31日 · Findings on echocardiography that suggest tamponade include the presence of a pericardial effusion, diastolic right ventricular collapse, systolic right atrial collapse, minimal respiratory variation of the inferior vena cava, and exaggerated changes in velocity across the mitral and tricuspid valve throughout the respiratory cycle ( Fig. 2 ). 9.
Computed tomography of the pericardium and pericardial disease
Computed tomography (CT) scanning provides a comprehensive anatomic and functional evaluation of the pericardium because of its high spatial and contrast resolution, fast acquisition (5–10 heart beats), multiplanar reconstruction capabilities, and large field of view.
Imaging-Guided Therapies for Pericardial Diseases
In the setting of acute and recurrent pericarditis, a noncalcified thickened smooth pericardium (>2.0 mm) with an associated pericardial effusion and iodinated contrast enhancement of the visceral and parietal surfaces are suggestive of ongoing inflammation . Should the contours have a more irregular shape, a certain degree of chronicity can be ...
