Restrictive cardiomyopathy versus constrictive pericarditis: making the distinction using tissue Doppler imaging

Echocardiography is the cornerstone for the diagnosis of pericardial disease. It is a portable technique allowing morphological and functional multimodality (M-mode, two-dimensional, Doppler, and tissue Doppler) imaging of pericardial disease. In addition, echocardiography is essential for differential diagnosis (pericardial effusion vs pleural effusion, constrictive pericarditis vs restrictive cardiomyopathy) and allows bedside guiding of pericardiocentesis. This chapter describes normal pericardial anatomy and reviews echocardiographic features of different pericardial diseases and their pathophysiology, including pericarditis, pericardial effusion, constrictive pericarditis, pericardial cyst, and congenital absence of pericardium.

Practical Geometry

In 1842, an Austrian professor of mathematics and practical geometry, Christian Doppler, presented results of his investigations in the field of astronomy, without any clue that they would become important principles of modern ultrasound diagnostics. Almost a century later, at the University of Osaka, Japan, S. Satomura first applied these principles to measure the blood flow velocities in peripheral and extracranial brain-supplying vessels. The father of tissue Doppler imaging is Karl Isaaz, a French scientist, who was the first to realize the importance of clinical and diagnostic potentials of tissue Doppler imaging. Today, this noninvasive echocardiographic method is widely used in evaluation of myocardial function, especially in diagnosing of diastolic heart failure and early diagnosis of coronary artery disease, but also in differential diagnosis of restrictive cardiomyopathy and constrictive pericarditis and aberrant myocardial conduction. It is also an antecedent of "stain rate", a new sensitive method for diagnosing myocardial diseses. .

Background: This study was designed to prospectively evaluate the changes in tissue Doppler imaging (TDI) at mitral and tricuspid annuli and two dimensional speckle tracking echocardiography in patients undergoing pericardiectomy for chronic constrictive pericarditis and identify the relationship if any of the tissue Doppler imaging and speckle echocardiographic derived variables with patient’s symptomatic status following surgery. Patients and Methods: Twelve patients undergoing pericardiectomy for constrictive pericarditis aged 7 years to 70 years (median 21; IQR: 19.75-26.5 years) were studied for 2-36 months (median 19 months). They underwent Doppler flow velocity, TDI, and 2D-speckle echocardiographic studies. Friedman’ test was used to test the changes in TDI-derived mitral and tricuspid annular velocities and speckle derived parameters in postoperative period from baseline. Results: Despite congestive heart failure, all patients had normal left ventricular ejection fraction and increased medial mitral and tricuspid early diastolic septal velocity (e¢) with “annulus reversus”. This pattern of annular velocity improved maximally in the immediate postoperative period. At closing interval, 2 (16.7%) patients continued to be in New York Heart Association class II and both of them continued to remain in atrial fibrillation. There was statistical significant improvement in the Global cirumferential strain than in global longitudinal and global radial strain after pericardiectomy. Conclusions: We conclude that tissue Doppler imaging and speckle tracking echocardiography are useful investigative modalities for serial evaluation of patients undergoing pericardiectomy. It can be performed serially with a high degree of reproducibility.
