• W4311752803 abstract "Abstract Introduction The diagnosis of constrictive pericarditis can be challenging through conventional imaging. Novel imaging techniques have been proposed to improve it. Clinical Case A 74-year-old man with a previous diagnosis of heart failure with preserved ejection fraction and permanent atrial fibrillation (AF) was admitted because of worsening dyspnea, peripheral edema, and ascites refractory to diuretics therapy. ECG revealed low QRS voltages and AF with normal heart rate and laboratory exams detected increased values of BNP and hepatic stasis indices; blood count and CRP were normal. Echocardiography revealed mildly reduced bi-ventricular pump function (left ventricular ejection fraction = 52%, right ventricular fractional area change = 25%) and slightly increased wall thickness. Atria were moderately dilated (left and right atrium 46 and 44 ml/mq, respectively) and mitral and tricuspid annuli were dilated too. There was inferior vena cava plethora, moderate atriogenic tricuspid regurgitation and mild-to-moderate atriogenic mitral regurgitation. A paradoxical interventricular septal motion and significant respiratory changes on trans-mitral (&gt;25%) and trans-tricuspid (&gt;30%) pulsed Doppler were noted; however, there was no annulus reversus (lateral and septal e’ 13 and 11 cm/sec, respectively) at TDI analysis. In contrast, 2D-speckle-tracking global longitudinal strain showed impaired deformation ​​of the lateral segments with relative sparing of the septal segments. The latter pattern has been recently described as strain reversus or hot septum sign. The findings were suspected of constrictive pericarditis, but a chest Computed Tomography excluded pericardial calcifications. Cardiac magnetic resonance (CMR) was then performed revealing a septal shift at cine-real time sequences analysis. The pericardium was slightly thickened (4-5 mm) with widespread late gadolinium enhancement but without signs of acute inflammation at T2-weighted imaging. Tricuspid regurgitation was confirmed to be moderate after phase-contrast imaging. Cardiac catheterization finally revealed normal coronary arteries and confirmed the diagnosis of constrictive pericarditis (square root sign, equalization of bi-ventricular end-diastolic pressures). The patient underwent pericardiectomy and tricuspid and mitral valve repair and was asymptomatic at 6-months follow-up. Conclusions Constrictive pericarditis represents a potentially reversible cause of heart failure but can be easily missed through conventional imaging. In the present case, advanced echocardiography and CMR were essential to come up with an accurate diagnosis, guiding the patient's clinical management with excellent outcome." @default.
