Abstract Introduction Some authors have confirmed changes in function of the right hearth in different conditions with endothelial dissfunction, such as systemic hypertension and metabolic syndrome. During gestational hypertension (GH), endothelial disfunction is one of the main pathogenic causes of vasoconstriction and placental insuficiety and following intrauterine growth restriction. Few authors evaluated function of the right ventricle during gestational hypertension, but to our knoledge, there are no studies about right atrial function during gestational hypertension. Purpose We hypothesized that there are changes in right atrial function durig gestational hypertension, and wondered if they are reversible. Methods Study included 45 pregnant women. 25 with GH (defined as blood pressure ≥140/90mmHg that appeared after 20th week of gestation and disappeared within six weeks postpartum) and 20 normotensivewomen,as control. Function of right atrium and right ventricle was evaluated according to the last guidelines for chamber quantification. Additionally, right atrial function was assessed with p-p cycle speckle tracking. Echo was performed in the third trimester of pregnancy and 6 weeks after delivery. Results Parameters showed impairment of RV diastolic function. Women with gestational hypertension had E/e" over the normal value and higher than healthy pregnants, althow difference was not significant. ( 6.46 +- 4.7 vs 5.16 +- 1.9, p =0.66). TDI derived E" from lateral tricuspid annulus was significantly lower in hypertensive group (0.11 +- 0.03 vs 0.14 +- 0.03 p= 0.023). Atv – right ventricle late filling velocity was significantly higher in patients with GH (0.61 +- 0.1 vs 0.51+-0.12, p= 0.08) . All pregnant women had normal values of RA dimensions, RA endsystolic area, RA endsystolic volume (RAVs). RAVs was significantly larger in GH group (34.64 +-12 vs 27.9+- 9.89, p= 0.041) comparing to the controls, but when we indexed it to the BSA, difference disappeared. Peak longitudinal strain was signfificantly higher in hypertensive group (33.49+- 2.48 vs 28.05+- 4.52, p= 0.001). After Pearson correlation of peak longitudinal strain with parameters of right ventricle diastolic function was done, there was possitive correlation between peak longitudinal strain and Etv (right ventricle early filling velocity) in hypertensive group (r 0.646, p 0.017). Also RAVs positively correlated with LAVsI (r= 0.577, p= 0.019), and RAVsI positively correlated with LAVsI (r= 0.690, p = 0.019). After delivery all changes disappeared. Conclusion Our study indicates that right atrium accommodates to the hemodynamic and functional changes during gestational hypertension. It changes because of modified right ventricle diastolic function and probably in the same mode as left atrium. RA peak longitudinal strain is high, so function of the right atrium is preserved, and we assume that short time of mentioned changes during pregnancy, is the reason why.

Abstract BackgroundRecently, the patient’s age of atrial septal defect (ASD) treatment has been gradually decreasing. However, the most appropriate age and treatment method remain controversial. We hypothesized that treatment of ASDs in patients under 5 years would be able to adequately normalize bi-atrial function over one year after treatment. The purpose of this study is to confirm the normalization of hypothesized atrial function.MethodsData of fifteen patients who underwent surgical ASD closure under 5 years of age (Operation group), 15 patients who underwent percutaneous ASD closure (Device group), and 15 age- and gender-matched normal control patients (Control group) were extracted from our echocardiographic data. Conventional 2D images and 2D speckle tracking method were used to evaluate bi-atrial function.ResultsLeft atrial function, εS, εE, and εA showed no significant differences in the three groups. Indicators representing the right atrial function varied with the three groups. However, there were no significant differences in the global longitudinal strain of the right atrium between the Operation and Device groups.ConclusionsAfter ASD treatment, right atrial function recovery is less than that of the left atrium. The function of the right atrium is not normalized after more than one year of treatment for ASD in patients under 5 years. After ASD treatment, further follow-up of the bi-atrial function is necessary.

Abstract A 68-year-old man was admitted to the hospital with complaints of pain in the lumbar spine. He had L5 disc herniation, Spinal stenosis of the L5 root canal - S1 on the right in the past medical history. Percutaneous vertebroplasty at the level of L3 and Th8 vertebral bodies was performed six months ago due to painful vertebral hemangioma. The man is suffering from arterial hypertension, receives antihypertensive therapy. During routine transthoracic echocardiography, a hyperechoic structure with a size of 9.5 x 0.9 cm was found in the right atrium and right ventricle. Chest computed tomography with contrast enhancement revealed signs of bone cement in the right atrium and right ventricle, in the right upper lobe artery, in the branches of the upper lobe artery, in the paravertebral venous plexuses. Considering the duration of the disease, the stable condition, the absence of clinical manifestations and disorders of intracardiac hemodynamics, it was decided to refrain from surgical treatment. Antiplatelet therapy and dynamic observation were recommended. Conclusion Percutaneous vertebroplasty is a modern minimally invasive surgical procedure for the treatment of degenerative-dystrophic diseases of the spine. However, the cement can penetrate into the paravertebral veins and migrate to the right chambers of the heart and the pulmonary artery. This clinical case demonstrates asymptomatic cement embolism of the right chambers of the heart and pulmonary artery after percutaneous vertebroplasty, detected incidentally during routine echocardiography.

We report the case of a patient with a giant right atrial myxoma that remained clinically silent until it almost completely obliterated the right atrium, prolapsed into the right ventricle and obstructed the tricuspid valve inflow. This case illustrates the importance of rapid surgical intervention in the setting of acute heart failure caused by tumor masses obliterating heart valves or cardiac chambers.

Abstract Löffler endocarditis with hypereosinophilic syndrome is rare but can cause critical ventricular obliteration by endomyocardial fibrosis. A 52-year-old woman experienced severe right heart failure with extreme shrinkage of her right ventricle, severe tricuspid regurgitation and marked right atrial enlargement. Preoperative tests showed identical pressures in the right atrium and pulmonary artery. Endocardial stripping was done, and to enlarge the right ventricle, we relocated the anterior and posterior tricuspid leaflets cephalad, up the right atrium wall, to ‘ventricularize’ a portion of the right atrium, with autologous pericardial augmentation of the tricuspid leaflets. An annuloplasty ring was added to reinforce the relocated tricuspid attachment. Right heart pressures normalized postoperatively. The patient recovered uneventfully. She has received corticosteroid therapy continuously and has shown no recurrence of heart failure in the 5 years since surgery.

Abstract Background Malformation of the right atrium is a rare cardiac abnormality and is usually reported as isolated malformation in the literature. Case presentation Prenatal giant atrial dilatation in an asymptomatic infant was treated surgically at 18 months of age, due to potential risk of thrombosis and arrhythmias. Post-surgical echocardiographic images illustrate residual atrial elevated pressure. Conclusions Sometimes, as seems in our case, right atrial dilatation hides an associated restrictive right ventricle.

The right atrium (RA) is located on the upper right-hand side of the heart and has relatively thin walls. From an anatomical point of view, the RA comprises three basic parts, the appendage, the vestibule of the tricuspid valve, and the venous component (superior and inferior vena cava, and the coronary sinus) receiving the deoxygenated blood. The RA is a dynamic structure dedicated to receive blood and to assist right ventricular (RV) filling. The three components of atrial function are the reservoir function during ventricular systole, the conduit function which consists in passive blood transfer from veins to the RV in diastole, and the booster pump function in relation to atrial contraction in late diastole to complete ventricular filling. Right atrial function depends on cardiac rhythm (sinus or atrial fibrillation), pericardial integrity, RV load and function, and tricuspid function. Right atrial dimension assessment is limited in two-dimensional (2D) echocardiography. Right atrial planimetry in the apical four-chamber view is commonly used with an upper normal value of 18-20 cm2. Minor and major diameters can also be measured. Three-dimensional (3D) echocardiography could overcome the limitation of conventional echocardiography in assessing RA size. Right atrial function has been poorly explored by echocardiography both in physiological and pathological contexts. Although tricuspid inflow and tissue Doppler imaging of tricuspid annulus can be used in the exploration of RA function, 2D speckle tracking and 3D echocardiography appear promising tools to dissect RA function and to overcome the limitations of standard echocardiography.

Abstract Purpose To investigate the relationship between right atrial deformation and the right ventricular size and function. Methods 94 patients with various cardiovascular pathologies have been included in the study group. All patients underwent transthoracic echocardiography with subsequent off-line analysis using speckle tracking technique and measurement of numerous right atrial deformation parameters, including peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS), as well as established indices of right ventricular size and function, including right ventricular basal diameter in apical four-chamber view (RVITd), tricuspid annular peak systolic excursion (TAPSE) and global longitudinal strain (GLS). Results There was a statistically significant weak correlation between RA strain (PACS and PALS) and RV parameters. RV-GLS showed significant correlation with PALS (r = -0,38; p = 0,0015) and PACS (r = - 0,30; p = 0,013). Similarly, TAPSE correlated with PALS and PACS (r = 0,34; p = 0,02) and (r = 0,23; p = 0,04) respectively. However, there was no correlation between right atrial function and RVIT. Conclusions Right atrial deformation parameters weakly correlate with right ventricular function indices and show no correlation with the size of the right ventricle.

Atrial and brain natriuretic peptides (ANP and BNP, respectively) are potent pulmonary vasodilators that are upregulated in hypoxia-adapted rats and may protect against hypoxic pulmonary hypertension. To test the hypothesis that C-type natriuretic peptide (CNP) also modulates pulmonary vascular responses to hypoxia, we compared the vasodilator effect of CNP with that of ANP on pulmonary arterial rings, thoracic aortic rings, and isolated perfused lungs obtained from normoxic and hypoxia-adapted rats. We also measured CNP and ANP levels in heart, lung, brain, and plasma in normoxic and hypoxia-adapted rats. Steady-state CNP mRNA levels were quantified in the same organs by relative RT-PCR. CNP was a less potent vasodilator than ANP in preconstricted thoracic aortic and pulmonary arterial rings and in isolated lungs from normoxic and hypoxia-adapted rats. Chronic hypoxia increased plasma CNP (15 ± 2 vs. 6 ± 1 pg/ml; P < 0.05) and decreased CNP in the right atrium (35 ± 14 vs. 65 ± 17 pg/mg protein; P < 0.05) and in the lung (3 ± 1 vs. 14 ± 3 pg/mg protein; P < 0.05) but had no effect on CNP in brain or right ventricle. Chronic hypoxia increased ANP levels fivefold in the right ventricle (49 ± 5 vs. 11 ± 2 pg/mg protein; P < 0.05) but had no effect on ANP in lung or brain. There was a trend toward decreased ANP levels in the right atrium (2,009 ± 323 vs. 2,934 ± 397 pg/mg protein; P = not significant). No differences in CNP transcript levels were observed between the two groups of rats except that the right atrial CNP mRNA levels were lower in hypoxia-adapted rats. We conclude that CNP is a less potent pulmonary vasodilator than ANP in normoxic and hypoxia-adapted rats and that hypoxia raises circulating CNP levels without increasing cardiopulmonary CNP expression. These findings suggest that CNP may be less important than ANP or BNP in protecting against hypoxic pulmonary hypertension in rats.
