Abstract
OBJECTIVES In animal models with constrictive pericarditis (CP), detecting the function of cardiac systole by conventional noninvasive ultrasound is a challenge. We aimed to detect cardiac dysfunction in rat models with CP in the early stage by layered speckle tracking. METHODS We compared a rat CP model (n = 23, injected with a solution of 1-mg/mL lipopolysaccharides [0.5 mL] and a 10% talc suspension [0.5 mL]) with a control group (n = 20, no injection). After 8 weeks, conventional echocardiography and layered speckle tracking were used to assess the left ventricular structures and functions in the groups. RESULTS The global circumferential strain (CS) and longitudinal strain (LS) were decreased in the CP group (P < .05). The CS of the epicardial and middle layers in the CP group was decreased (P < .05), but the endocardial layer was not statistically different. The LS of the epicardial layer was decreased (P < .05), but the middle and endocardial layers were not statistically different. The global free-wall and septal-wall CS of the CP group was decreased (P < .05), mainly due to the decrease of CS of the epicardial and middle layers. The global free-wall LS of the CP group was decreased (P < .05), mainly due to the decrease of LS of the epicardial and middle layers. There were no significant differences between the groups in global LS of the septal wall. CONCLUSIONS In the early stage of CP, subepicardial myocardial damage precedes that of the subendocardial myocardium, and free-wall damage precedes that of the septal wall.

Evaluation of Long-Term Impact of Pericardiectomy on Left Atrial Functions in Patients with Constrictive Pericarditis Using Speckle Tracking Echocardiography. ULTRASOUND IN MEDICINE & BIOLOGY 2020; 46:1158-1168. [PMID: 32107091 DOI: 10.1016/j.ultrasmedbio.2020.01.020] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 01/03/2020] [Accepted: 01/20/2020] [Indexed: 06/10/2023]
Abstract
The aims of this study were to explore the long-term impact of pericardiectomy on left atrial (LA) functions in patients with constrictive pericarditis (CP) using speckle tracking echocardiography (STE) and to correlate post-operative LA functions with clinical status. Echocardiographic examinations were undertaken in 29 patients with CP 1 wk before and 1, 6 and 12 mo after pericardiectomy. STE was performed to obtain LA global longitudinal strain, including strain during the conduit phase (LAScd), strain during the contraction phase (LASct) the sum of the latter and strain during the reservoir phase (LASr). Control patients consisted of 29 age- and sex-matched healthy volunteers. LASct, LAScd and LASr obtained 6 mo after pericardiectomy improved significantly compared with pre-operative values, but were still lower than the values for control patients. Further increases were observed gradually with normalization of LASct 12 mo after pericardiectomy. However, there were still significant differences between LAScd and LASr obtained in control patients and those obtained 12 mo after pericardiectomy. Moreover, the improvements in LAScd, LASct and LASr 12 mo after pericardiectomy correlated well with symptomatic clinical alleviation (p < 0.01). These results indicate that LA strains analyzed with STE might be useful in evaluating the long-term impact of pericardiectomy on LA functions.

Incremental Value of the Tissue Motion of Annular Displacement Derived From Speckle-Tracking Echocardiography for Differentiating Chronic Constrictive Pericarditis From Restrictive Cardiomyopathy. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2018; 37:2637-2645. [PMID: 29603321 DOI: 10.1002/jum.14625] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Revised: 01/14/2018] [Accepted: 02/08/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVES The tissue motion of annular displacement provides an accurate and rapid assessment of left ventricular (LV) systolic function. However, it has rarely been used in patients with chronic constrictive pericarditis and restrictive cardiomyopathy. This study aimed to assess the differences in LV systolic function in patients with constrictive pericarditis and restrictive cardiomyopathy using tissue motion of annular displacement derived from speckle-tracking echocardiography. METHODS Twenty-four patients with constrictive pericarditis, 24 with restrictive cardiomyopathy, and 25 healthy volunteers (controls) were enrolled. The septal and lateral mitral annular longitudinal displacements, displacement at the midpoint, and normalized midpoint displacement of the mitral ring were calculated. RESULTS Mitral annular tracking and quantification of the tissue motion of annular displacement were achieved within 10 seconds. In patients with constrictive pericarditis, the lateral mitral annular longitudinal displacement, displacement at the midpoint, and midpoint displacement of the mitral ring were decreased, whereas the septal mitral annular longitudinal displacement was preserved compared to controls, indicating that the reduction of systolic function in constrictive pericarditis was caused by pericardial adhesion and calcium. In patients with restrictive cardiomyopathy, tissue motion of annular displacement was more reduced compared to patients with constrictive pericarditis and controls. The correlation between the septal mitral annular longitudinal displacement and left ventricular ejection fraction was 0.67 (P < .001). A cutoff value of 8.45 mm for the septal mitral annular longitudinal displacement could effectively differentiate constrictive pericarditis from restrictive cardiomyopathy with 95.2% sensitivity and 91.7% specificity. CONCLUSIONS The tissue motion of annular displacement was decreased in patients with constrictive pericarditis, which indicated early impairment of longitudinal function in constrictive pericarditis; adhesion and calcium in the pericardium might account for the reduction. The septal mitral annular longitudinal displacement provides a fast and effective method for the assessment of LV systolic function in patients with constrictive pericarditis and restrictive cardiomyopathy.

Abstract
BACKGROUND Coronary slow-flow phenomenon (CSFP) is an angiographic diagnosis characterized by delayed coronary opacification in the absence of obstructive coronary artery disease. Currently, several investigators are focusing on ventricular function assessment in patients with CSFP; however, there is a paucity of data on their atrial function. This study was performed to evaluate left atrial (LA) and right atrial (RA) function in patients with CSFP. MATERIALS AND METHODS Eighty-two patients with CSFP and 55 controls without CSFP were enrolled in the study. Diagnosis of CSFP was made by thrombolysis in myocardial infarction frame count (TFC). The LA and RA global longitudinal strain and strain rate during systole (Ss, SRs), during early diastole (Se, SRe), and during late diastole (Sa, SRa) were measured using two-dimensional speckle tracking echocardiography. RESULTS In the CSFP group, LA Se and SRe decreased, while LA Sa and SRa increased, compared with the control group. RA Se and SRe were lower in patients with CSFP than in the controls. CONCLUSIONS LA conduit function decreased in patients with CSFP, while contractile function increased. RA conduit function also decreased in patients with CSFP.
