Three-dimensional speckle tracking echocardiography for evaluation of ventricular function in patients with systemic lupus erythematosus: relationship between duration of lupus erythematosus and left ventricular dysfunction by using global longitudinal strain.

BACKGROUND: Cardiovascular diseases are leading causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Cardiac involvement in SLE can often go undetected. Three-dimensional (3D) speckle tracking echocardiography (STE) is a noninvasive imaging technique that can assess the function of the heart's ventricles in an accurate and reproducible way. This makes it an attractive option for detecting early signs of heart disease in SLE patients. By identifying these subclinical cardiac abnormalities, 3D-STE may help reduce the negative impact of cardiovascular diseases in SLE population. Therefore, this study aimed to compare the left ventricular (LV) function between patients with SLE compared to age- and gender-matched controls using two-dimensional (2D) and 3D-STE. RESULTS: The current study found no significant differences in left ventricle ejection fraction, left ventricle end-diastolic volume, left ventricle end-systolic volume, left ventricle end-diastolic mass, and left ventricle end-systolic mass between the two groups. However, the SLE group exhibited a significantly lower LV global longitudinal strain (GLS) compared to the control group according to all types of echocardiographic assessments, including 3D and 2D long-axis strain, apical 2-chamber, and apical 4-chamber assessments (all P values < 0.05). Furthermore, a good inter-rater reliability and intra-rater reliability were observed regarding the LVGLS measurement with 3D-STE. Additionally, the study identified a significant correlation between LVGLS and SLE duration (r (50) = 0.46, P < 0.001). The use of prednisolone and nephrology disorders was also found to impact LVGLS measurements. CONCLUSIONS: Despite a normal LVEF in patients with SLE, LVGLS measurements indicated that LV systolic dysfunction was observed more frequently in SLE patients compared to their healthy counterparts. Therefore, advanced 3D-STE techniques may be useful in identifying subtle abnormalities in LV function in SLE patients.

Clinical presentation, diagnostic evaluation, and management of undifferentiated/unclassified cardiac sarcoma: A case report and literature review.

This case report details a challenging instance of undifferentiated/unclassified cardiac sarcoma in a 28-year-old female, presenting with diverse symptoms like muscle weakness, shortness of breath, and hemoptysis. Diagnostic hurdles led to an initial misdiagnosis of granulomatosis with polyangiitis before discovering a sizable left atrial mass, ultimately diagnosed as high-grade undifferentiated/unclassified sarcoma. Despite initial surgical intervention, the patient's condition worsened, underscoring the complexities in managing such cases involving cardiac sarcomas. This case emphasizes the diagnostic complexities associated with primary cardiac sarcomas, particularly the challenges in achieving accurate diagnoses and formulating effective treatment strategies.

Intravenous thrombolysis in a patient with acute ischemic stroke associated with a ruptured sinus Valsalva aneurysm: The first case report.

Sinus Valsalva aneurysms (SVA) are rare asymptomatic cardiac anomalies, which can rupture and cause heart failure, myocardial infarction and also, they can be a potential source for embolic strokes. We report the first case of a patient with acute ischemic stroke associated with a ruptured SVA, who was treated with intravenous thrombolysis (tPA) without further complications.

Evaluating the Role of lncRNAs in the Incidence of Cardiovascular Diseases in Androgenetic Alopecia Patients.

Hair loss occurs in patients with Androgenetic Alopecia (AGA). The pattern of hair loss is different between men and women. The main cause of hair loss is increased cell apoptosis and decreased regeneration, proliferation and differentiation processes in hair follicles. Long Non-Coding RNAs (lncRNAs) are one of the most important molecules that regulate the processes of apoptosis, regeneration, proliferation and differentiation in hair follicles. Since studies have shown that lncRNAs can be effective in the development of cardiotoxicity and induction of cardiovascular disease (CVD); so effective lncRNAs in the regulation of regeneration, proliferation, differentiation and apoptosis of hair follicles can be involved in the development of CVD in AGA patients with. Therefore, this study investigated the lncRNAs involved in increasing apoptosis and reducing the processes of regeneration, proliferation and differentiation of hair follicles. The aim of the current study was to evaluate the role of lncRNAs as a risk factor in the incidence of CVD in AGA patients; it will help to design treatment strategies by targeting signaling pathways without any cardiotoxicity complications.

Exosomes: Potential Player in Endothelial Dysfunction in Cardiovascular Disease.

Exosomes are spherical bilayer membrane vesicles with an average diameter of 40-100 nm. These particles perform a wide range of biological activities due to their contents, including proteins, nucleic acids, lipids, lncRNA, and miRNA. Exosomes are involved in inflammation induction, oxidative stress and apoptosis, which can be effective in endothelial dysfunction. Due to the induction of mentioned processes in the endothelial cells, the intercellular connections are destroyed, cell permeability increases and finally cell efficiency decreases and functional defects occur. Cardiovascular disease (CVDs) are of consequences of endothelial dysfunction. Thus by identifying the exosome signaling pathways, which induce inflammation, oxidative stress, and apoptosis, endothelial dysfunction and subsequently CVDs can be reduced; exosomes can be used for appropriate target therapy.

The relationship between global longitudinal strain and pulmonary function tests in patients with scleroderma and normal ejection fraction and pulmonary artery pressure: a case-control study.

This study examined the relationship between global longitudinal strain (GLS) and pulmonary function tests (PFT) in patients with systemic sclerosis (SS) and normal ejection fraction (EF) and pulmonary artery pressure (PAP) and healthy controls. Sixty patients in two groups underwent extensive screening, including echocardiography, physical examination, the modified Rodnan Skin Score, and pulmonary function tests. Pulmonary interstitial disease was diagnosed by the pulmonary function test and by CT scan in case of indication. GLS score was computed as the mean peak systolic strain for 17 segments. The mean GLS score was - 18.36 ± 2.1 in the case group and - 20.66 ± 1.6 in the control group (P value < 0.001). GLS scores had a significant inverse relationship with the forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ratio (P value = 0.049) and both FEV and FVC in patients younger than 35 years old (P = 0.046 and 0.049, respectively). GLS scores had no significant relationship with time elapsed since the onset of skin manifestations, and Raynaud phenomenon, Rodnan score, EF, systolic PAP, or the six-minute walk test results. The patients' six-minute walk test had a significant positive relationship with FVC and right ventricular end diastolic diameter (P value = 0.018 and 0.047, respectively). According to our findings, GLS is significantly lower in patients with SS (with normal EF & PAP) than in healthy individuals. It is also related with certain pulmonary function indices including FEV1/FVC. The reduction in GLS is associated with reduced pulmonary function strength.

Aortic valve cusp aneurysm as a result of blood culture-negative infective endocarditis, interesting echocardiographic and surgical images.

Compared to mitral valve aneurysms, aortic valve (AV) aneurysm is a more rare and serious complication of infective endocarditis (IE). Early surgical intervention and valve replacement are required in order to prevent further complications such as embolization and rupture of aneurysm. We described a case of severe aortic regurgitation (AR) as a result of an aortic valve aneurysm in a patient with history of end-stage renal disease (ESRD) in whom the hemodialysis catheter had not been changed for a year.

The Presence of Patent Foramen Ovale in the Superior Type of Sinus Venosus Atrial Septal Defect.

Background: The superior type of sinus venosus atrial septal defect (SVASD) is a rare form of the atrial septal defect (ASD) in which the upper part of the atrial septum does not exist. The presence of other cardiac anomalies such as anomalous pulmonary venous connections has been reported in this type of congenital heart disease. This study aimed to assess the presence of the patent foramen ovale (PFO) in patients with the superior type of SVASD. Methods: This retrospective case-control study on 387 patients, consisting of 187 patients with a definite SVASD and 200 patients with problems other than the ASD, was conducted in Rajaie Cardiovascular Medical and Research Center between February 2005 and July 2014. Seven patients with inadequate data were excluded from the analysis. The presence/absence of the PFO was also evaluated in the case and control groups. Results: The analyses were performed on 182 male and 198 female patients at a mean age of 39.07±14.41 and 51.01±15.80 years in the case and control groups, respectively. The PFO was significantly more frequent in the patients with the superior type of SVASD than in those without the condition (P<0.001). The persistence of the left superior vena cava was seen in 34 out of 180 patients with SVASD and in 1 out of 200 patients without the condition (18.9% vs 0.5%; P<0.001). Conclusion: This study was the first to highlight the coexistence of the PFO and the superior type of SVASD. Physiological, genetic, or fetal factors may play an important role in the association between the PFO and the SVASD.

Postinfarction intramyocardial dissection, an interesting case report and systematic review.

Intramyocardial dissection (IMD) with ventricular septal rupture (VSR) following myocardial infarction (MI) is a rare subacute form of cardiac rupture. The evidence available in this regard is scarce. We aimed to share our experience and conduct a systematic review of previous cases. We searched the literature and performed a systematic review of previous cases. A total of 37 cases of IMD with VSR were included (1 our original and 36 literature cases). Mean age was 68 ± 8 years and 20 (54.1%) patients were male. Anterior and inferior MI were observed in 14 (37.8%) and 23 (62.2%) cases, respectively. The dissected area was the septum, RV, both septum and RV, or LV apex in 21 (56.8%), 9 (24.3%), 5 (13.5%), and 2 (5.4%), respectively. Apicoseptal and inferoseptal VSR were observed in 15 (40.5%) and 22 (59.5%) cases, respectively. At least one occluded artery was observed in 29 (90.6%) of cases. Reperfusion therapy was done for 15 (40.5%) cases before the VSR occurred. Surgery, percutaneous, and medical therapy were done for 26 (70.3%), 3 (8.1%), and 7 (18.9%) cases, respectively. The mortality rate was significantly higher in the medical versus surgical-treated group (85.7% versus 42.3%, P = .027). There was a trend to higher mortality in the group with dissection of both septum and RV (P = .15). We concluded that echocardiography has a critical role in diagnosing this complication. Surgery is mandatory in IMD with VSR.

The correlation between cardiac magnetic resonance T2* and left ventricular global longitudinal strain in people with ß-thalassemia.

BACKGROUND: Heart failure is the biggest cause of mortality and morbidity in people with thalassemia, and iron deposition in cardiac tissue impairs cardiovascular function. Therefore, early detection of cardiac involvement is important to improve the prognosis in these individuals. METHOD: Two- and three-dimensional echocardiography was performed to evaluate left ventricular ejection fraction (LVEF), left ventricular volumes and diameters, and global longitudinal strain (GLS) in 130 individuals with ß-thalassemia using the speckle tracking method. Magnetic resonance imaging (MRI) was carried out on both the heart and liver. The participants were divided into 2 groups based on cardiac T2* values (normal and abnormal cardiac iron load), and the correlation between cardiac T2* MRI and GLS was evaluated. RESULTS: The statistical analysis showed a significant correlation between cardiac T2* MRI and left ventricular global longitudinal strain. There was a significant difference in global longitudinal strain (P < .0001), liver MRI T2*( P < .0001), and left ventricular ejection fraction (P < .001) between the 2 groups. The optimal cutoff value for GLS was -18.5% with sensitivity and specificity 73.0% and 63.0%, respectively (postitive predictive value = 50%, negative predictive value = 82.3%, AUC = 0.742, std. error = 0.046) which predicts T2* value of <20 ms, according to cardiac MRI. CONCLUSIONS: The participants with cardiac iron overload had a lower GLS than those without one. This suggests that GLS may be a useful method to predict myocardial iron overload particularly in ß-thalassemia patients with subclinical cardiac involvement.

Right ventricular myxoma originating from a papillary muscle: a case report.

Very few cases of ventricular myxoma originate from a papillary muscle. Patients with a cardiac myxoma and a history of colorectal carcinoma are also rare. Here, we present a case of an extremely large right ventricular myxoma that originated from the posteromedial papillary muscle in a patient with a history of colorectal carcinoma.

Giant congenital left ventricular diverticulum associated with infective endocarditis: A diagnosis made by tissue Doppler echocardiography.

Left ventricular (LV) diverticulum is a relatively rare condition, and it is important to differentiate it from pseudoaneurysm. The increasing use of noninvasive imaging modalities can help to demonstrate different types of ventricular outpouching structures. We report a case of congenital LV diverticulum that is much larger than the usual size and is diagnosed with tissue Doppler echocardiography and cardiac magnetic resonance imaging. Although a ventricular diverticulum is mostly asymptomatic, in the case of this particular patient, it has become complicated with infective endocarditis. .
