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 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.

Background: Although various synthetic materials and pericardium have been used for atrial septal defect (ASD) closure, investigators are continuing to search for an ideal material for this procedure. We report and evaluate a case in which autologous right atrial wall tissue was used for ASD closure. Case: In this case, we closed a secundum ASD of a 22-year-old woman who also had right atrial enlargement due to the defect. After establishing standard bicaval cannulation and total cardiopulmonary bypass, we opened the right atrium with an oblique incision in a superior position to a standard incision. After examining the secundum ASD, we created a flap on the inferior rim of the atrial wall. A stay suture was stitched between the tip of the flap and the superior rim of the defect, and suturing was continued in a clockwise direction thereafter. Considering the size and shape of the defect, we incised the inferior attachment of the flap, and suturing was completed. Remnants of the flap on the inferior rim were resected, and the right atrium was closed in a similar fashion. Results: During an echocardiographic examination, neither a residual shunt nor perigraft thrombosis was seen on the interatrial septum. The patient was discharged with complete recovery. Conclusion: Autologous right atrial patch is an ideal material for ASD closure, especially in patients having a large right atrium. A complete coaptation was achieved because of the muscular nature of the right atrial tissue and its thickness, which is a closer match to the atrial septum than other materials.

Objective. To assess the effectiveness of a novel ultrasound wire for echo-guiding percutaneous atrial septal defect (ASD) closure in a sheep model. Methods. After right lateral thoracotomy, ASDs were created in 20 sheep by transseptal needle puncture followed by balloon dilatation. Animals were evenly randomized into 2 groups to undergo ASD closure using echography as the only imaging tool with either COOK wire (control group) or new ultrasound wire (study group). The total procedural time, passing time (time needed for the guide wire to enter the left atrium), frequency of delivery sheath dropping into the right atrium, frequency of arrhythmias, and 1-week rate of complications were compared between the two groups. Results. All animals survived defect creation procedures uneventfully. ASD devices were successfully implanted in all sheep. Compared with the control group, the study group had significantly (P<0.05) lower mean procedure time (15.36 ± 4.86 versus 25.82 ± 7.85 min), lower mean passing time (2.69 ± 0.82 versus 5.58 ± 3.34 min), lower frequency of the guide wire dropping into the right atrium (0% versus 40%), and lower frequency of atrial (4.41 ± 2.61 versus 9.60 ± 3.68) or ventricular premature contractions (0.75 ± 0.36 versus 1.34 ± 0.68), respectively, without serious complications up to one week. Conclusion. The novel ultrasound specialized guide wire was effective in echo-guiding percutaneous ASD closure.

Right Atrial Function

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 Background Closure of all haemodynamically significant atrial septal defects (ASDs) is recommended irrespective of symptoms. Percutaneous device closure offers a favourable alternative to surgery with lower morbidity, shorter duration of hospital stays, and avoidance of a surgical scar. Though device closure is generally a safe procedure with high success rates, certain complications can arise including device embolization which poses a significant challenge for the treating team. We report one such case in which the ASD closure device got spontaneously released and embolized from the delivery cable into the left atrium prior to its deployment. We describe our approach for its retrieval and subsequently its successful deployment across the septal defect using a gooseneck snare. Case presentation A 5-year-old asymptomatic child was found to have a murmur on a routine check-up. Evaluation revealed a haemodynamically significant, 18-mm ostium secundum ASD with normal pulmonary pressures and suitable margins for device closure. A 20-mm ASD closure device was traversed via an 8-Fr delivery system. While manipulating the left atrial (LA) disc from the right upper pulmonary vein (RUPV) approach, the device got spontaneously released. The right atrial (RA) disc was caught across the ASD, into the left atrium. This was confirmed by intraoperative transthoracic echocardiography and fluoroscopy. The haemodynamics and rhythm were stable. A 20-mm gooseneck snare was immediately passed through the delivery sheath and an attempt was made to catch the screw. With difficulty, the RA screw was caught with the snare and multiple attempts to retrieve the device into the sheath were unsuccessful. However, while negotiating, we were able to secure a favourable position of the device across the atrial septal defect, and after fluoroscopic and echocardiographic confirmation, the device was released. The child remained stable thereafter and was discharged 2 days later. Conclusions Gooseneck snare is a valuable tool in the management of embolized ASD closure device. Occasionally, like in the index case, one may be successful in retrieving the embolized device and repositioning it across the ASD using a gooseneck snare, thus obviating the need for emergency surgery.

To determine whether the echocardiographic presentation allows for diagnosis of acromegalic cardiomyopathy. 140 patients with acromegaly underwent echocardiography as part of routine diagnostics. The results were compared with the control group comprising of 52 age- and sex-matched healthy volunteers. Patients with acromegaly presented with higher BMI, prevalence of arterial hypertension, and glucose metabolism disorders (i.e., diabetes and/or prediabetes). In patients with acromegaly, the following findings were detected: increased left atrial volume index, increased interventricular septum thickness, increased posterior wall thickness, and increased left ventricular mass index, accompanied by reduced diastolic function measured by the following parameters: E’med., E/E’, and E/A. Additionally, they presented with abnormal right ventricular systolic pressure. All patients had normal systolic function measured by ejection fraction. However, the values of global longitudinal strain were slightly lower in patients than in the control group; the difference was statistically significant. There were no statistically significant differences in the size of the right and left ventricle, thickness of the right ventricular free wall, and indexed diameter of the ascending aorta between patients with acromegaly and healthy volunteers. None of 140 patients presented systolic dysfunction, which is the last phase of the so-called acromegalic cardiomyopathy. Some abnormal echocardiographic parameters found in acromegalic patients may be caused by concomitant diseases and not elevated levels of GH or IGF-1 alone. The potential role of demographic parameters like age, sex, and/or BMI requires further research.

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.

Hepatocellular carcinoma usually metastasizes to regional lymph nodes, lung, and bones but can rarely invade the inferior vena cava with intravascular extension to the right atrium. We present the case of a 75-year-old man who was admitted for generalized oedema and was found to have advanced HCC with invasion of the inferior vena cava and endovascular extension to the right atrium. In contrast to the great majority of hepatocellular carcinoma, which usually develops on the basis of liver cirrhosis due to identifiable risk factors, none of those factors were present in our patient.
