MiRNA-1 may participate in regulating ischemia-reperfusion injury (IRI) by affecting the expression and distribution of connexin 43 (Cx43). The aim of this study is to investigate miR-1 expression and its potential role in regulating Cx43 during ischemic postconditioning (IPOST) in a rat model. Fifty-five Wistar male rats were randomly divided into five groups: N, IR, IPOST, agomir-1, and antagomir-1 group. The hearts were perfused with the Langendorff system. The reperfusion arrhythmia (RA) and myocardial infarct size were observed and recorded...

Most cases of atrial myxoma are sporadic, and the exact etiology is unknown. We examined if herpes simplex virus (HSV)-1 and HSV-2 antigens and/or DNA could be detected in a cohort of Iranian patients with cardiac myxomas. From July 2004 to June 2014, among a total of 36,703 patients undergoing open heart surgeries, consecutive patients with cardiac myxoma who were treated by surgical excision at our center included in this study. Of 73 patients studied, 56% were female with a mean age of 54 years (ranging from 23 to 77 years)...

We present results of the histopathological workup of a prosthetic aortic valve which was explanted from a 31-year-old woman due to valve thrombosis during early pregnancy. Our images demonstrate nicely thrombotic material directly adherent to the pyrolytic carbon surface in a human specimen.

BACKGROUND: Scavenger receptor class B type 1 (SR-BI) is the main high-density lipoprotein (HDL) receptor in mammalians. Loss of SR-BI has been proven to disturb HDL metabolism and accelerate atherosclerosis. However, little is known about the plaque features and arterial remodeling in the increased atherogenesis caused by SR-BI deficiency. Here, we explored this issue in atherosclerosis-prone low-density lipoprotein receptor (LDL-R) knockout (KO) mice deficient of SR-BI. METHODS AND RESULTS: SR-BI/LDL-R double KO (dKO) and control LDL-R KO mice were fed an atherogenic diet for 12 weeks...

BACKGROUND: Monocyte chemoattractant protein-1 (MCP-1)-mediated inflammatory mechanisms have been shown to play a crucial role in atrial fibrosis induced by pressure overload. In the present study, we investigated whether left atrial endothelial cells would quickly respond structurally and functionally to pressure overload to trigger atrial fibrosis and fibrillation. METHODS AND RESULTS: Six-week-old male Sprague-Dawley rats underwent suprarenal abdominal aortic constriction (AAC) or a sham operation...

Evidence suggests that store-operated Ca2+ entry (SOCE) is involved in the hypertrophy of cardiomyocytes. The signaling mechanisms of SOCE contributing to cardiac hypertrophy following phenylephrine (PE) stimulation are not fully understood. Ca(2+)/calmodulin-dependent protein kinase II δ (CaMKIIδ) plays an important role in regulating intracellular Ca(2+) hemostasis and function in the cardimyocytes. This study is aimed to determine the role of CaMKIIδ in regulating the PE-induced myocardial hypertrophy and the associated molecular signaling mechanisms...

Genome-wide association studies have shown that Krüppel-like factor 14 (KLF14) is associated with both Type 2 diabetes mellitus and lipid metabolism. However, its role in chronic inflammatory responses and the pathogenesis of atherosclerosis remains unknown. The present study was designed to investigate both in vivo and in vitro the impact of KLF14 on chronic inflammatory responses and atherosclerosis. ApoE KO mice, a well-established animal model of atherosclerosis, had higher expressions of KLF14 in aorta tissues than that in C57BL/6 J mice when fed the high-fat diet (HFD) or standard chow diet...

BACKGROUND: Spontaneously hypertensive rats (SHR) serve as a model of genetic hypertension. Adverse remodeling of a coronary artery has been reported in SHR. This model is used to study new therapies in regression vascular remodeling. However, no data are available that show remodeling of the intramyocardial branch of the obtuse marginal artery in 10-month-old SHR. This study was designed to assess remodeling (changes in vascular structure and fibrosis) of this coronary artery. METHODS AND RESULTS: The study was performed on 10-month-old male SHR (n=7) and normotensive control Wistar Kyoto rats (WKY) (n=7)...

Biomechanical characterization of the aortic wall may help risk stratify patients with aneurysms. We investigated the degree of anisotropy, the directional dependency of mechanical properties, in control and aneurysmal ascending aortic tissue. We hypothesized that medial degeneration and aortic wall remodeling as found in aneurysmal tissue alter energy loss in both the circumferential and longitudinal directions, thereby reducing anisotropy. Aneurysmal and control ascending aortic tissue excised during surgery was subjected to biaxial tensile testing...

The aim of this study was to estimate the incidence and to analyze the anatomy of double inlet-double outlet right ventricle complex and its associated cardiac anomalies in our autopsy series. Among the 1640 hearts with congenital heart disease of our Anatomical Collection, we reviewed the specimens with double inlet-double outlet right ventricle, according to the sequential-segmental analysis, identifying associated cardiac anomalies and examining lung histology to assess the presence of pulmonary vascular disease...

BACKGROUND: In-stent neoatherosclerosis is characterized by the delayed appearance of markers of atheroma in the subintima, but the pathophysiology underlying this new disease entity remains unclear. METHODS AND RESULTS: We collected 20 human coronary artery stents by removal from explanted hearts. The mean duration of stent implantation was 34 months. In all samples, neoatherosclerosis was detected, particularly in peristrut areas. It consisted of foam cells and cholesterol clefts, with or without calcification, associated with neovascularization...

BACKGROUND: Autonomic remodeling, characterized by sympathetic activation and vagal withdrawal, contributes to heart failure (HF) progression. However, the exact mechanism(s) responsible for vagal withdrawal in HF remain(s) unclear, and whether HF causes epicardial autonomic nerve remodeling is unknown. METHODS AND RESULTS: Myocardial infarction (MI) was produced in 14 Sprague-Dawley rats, and 10 sham surgery rats served as the control. MI-HF was confirmed 2 months after the surgery by echocardiography and hemodynamic measurement...

Dilated cardiomyopathy (DCM) is associated with extensive pathological cardiac remodeling and involves numerous changes in the protein expression profile of the extracellular matrix of the heart. We obtained seven human, end-stage, failing hearts with DCM (DCM-failing) and nine human, nonfailing donor hearts and compared their extracellular matrix protein profiles. We first showed that the DCM-failing hearts had indeed undergone extensive remodeling of the left ventricle myocardium relative to nonfailing hearts...

Woven coronary artery is a rare anomaly characterized by thin channels arising from the coronary artery and reanastomosing at the distal arterial segment. To our knowledge, no data are available currently on the histologic structure of the woven segment. A 39-year-old man presented with sudden atypical chest pain while he was practicing cycling. During the transfer of the patient to the hospital, he suffered cardiac arrest. After 50 min of cardiopulmonary resuscitation, the patient could not return to sinus rhythm and died...

Vascular changes observed in intralobar pulmonary sequestration (PS) have been reported to be similar to those observed in pulmonary hypertension (PH). However, atherosclerosis in the pulmonary artery, which is one of the characteristic arterial changes of PH, has scarcely been reported in PS. Here, we report this unique manifestation in a 66-year-old man, in whom an intralobar PS fed by an aberrant artery branching from the left gastric artery had been identified 10 years earlier, and who was diagnosed with pneumonia after having symptoms of fever and cough...

A 27-year-old male, admitted to hospital for a psoas muscle abscess secondary to Crohn's disease, suddenly died while in hospital. A medicolegal autopsy showed coronary sinus thrombosis. Coronary sinus thrombosis is rare and is usually associated with invasive cardiac procedures. Coronary sinus thrombosis associated with Crohn's disease has not been reported. Autopsy examination of the coronary sinus is advocated, especially in individuals with hypercoagulable states.

We describe the case of a 3-year-old girl who presented with a large, mobile, ball mass in the right atrium on routine transthoracic echocardiography at one year after an intraatrial repair. Considering the risk of pulmonary embolization, emergent surgery was successfully performed to remove the mass, and histopathological examination revealed that it was a ball thrombus with a fibrin clot.
