AbstractThe right ventricle´s (RV) characteristics—thin walls and trabeculation—make it challenging to evaluate extracellular volume (ECV). We aimed to assess the feasibility of RV ECV measurements in congenital heart disease (CHD), and to introduce a novel ECV analysis tool. Patients (n = 39) and healthy controls (n = 17) underwent cardiovascular magnetic resonance T1 mapping in midventricular short axis (SAX) and transverse orientation (TRANS). Regions of interest (ROIs) were evaluated with regard to image quality and maximum RV wall thickness per ROI in pixels. ECV from plane ROIs was compared with values obtained with a custom-made tool that derives the mean T1 values from a “line of interest” (LOI) centered in the RV wall. In CHD, average image quality was good (no artifacts in the RV, good contrast between blood/myocardium), and RV wall thickness was 1–2 pixels. RV ECV was not quantifiable in 4/39 patients due to insufficient contrast or wall thickness < 1 pixel. RV myocardium tended to be more clearly delineated in SAX than TRANS. ECV from ROIs and corresponding LOIs correlated strongly in both directions (SAX/TRANS: r = 0.97/0.87, p < 0.001, respectively). In conclusion, RV ECV can be assessed if image quality allows sufficient distinction between myocardium and blood, and RV wall thickness per ROI is ≥ 1 pixel. T1 maps in SAX are recommended for RV ECV analysis. LOI application simplifies RV ECV measurements.

Timely Treatment

The birth of children with congenital heart disease is a serious problem due to the risk of infant mortality. Clinically, the atrial septal defect belongs to the low manifest defects. The severity of its symptoms depends on the size and location of the defect, as well as, to a greater extent, on the duration of the defect and the development of secondary complications. This situation dictates the need for early diagnosis of this congenital heart disease, dynamic observation, timely treatment, which determines the relevance of this study. In this article, we tried to analyze and evaluate in detail the results of ECG and EchoCG of newborns with interatrial communications. We carried out a retrospective analysis of 94 case histories of full-term newborns who are undergoing inpatient examination and treatment in the hospital of the city of Saransk for the period from December 2016 through March 2018. In the course of our study, it was found that the ECG study does not reveal specific signs suggesting the presence of MPS. Nevertheless, attention should be paid to the position of the electrical axis of the heart, the presence of signs of overloading of the right heart, especially the right ventricle. When EchoCG is studied in newborns with MPS, and more often with MPS sizes greater than 4 mm, an increase in the right ventricle and thickening of its anterior wall are diagnosed.

Abstract Introduction Ebstein’s anomaly is characterized by displacement of the proximal attachments of the tricuspid valve from the atrioventricular ring into the right ventricle. This structural abnormality divides the right ventricle into an ‘atrialized’ portion and a distal ‘ventricularized’ portion. The severity is variable and accounts for the broad clinical spectrum, from severe disease causing fetal or neonatal death to mild disease compatible with natural survival as late as the eighth decade of life. Ebstein’s anomaly is an uncommon defect occurring in less than 1% of patients with congenital heart disease, but it is disproportionately represented in the adult congenital heart disease population because of its favourable natural history Case report A 55 year old man with no previous cardiac history .He presented to our medical facility complaining of acute retrosternal squeezing retrosternal chest pain few hours before admission. On clinical examination, he had a pansystolic murmur over the tricuspid area .ECG showed right bundle branch block. Laboratory results were unremarkable except elevated cardiac enzymes. 2D Transthoracic Echocardiography revealed a small well-functioning right ventricle, 15 mm/m2 apical displacement of the tricuspid septal leaflet with severe tricuspid regurgitation . 2D and 3D transesophageal echocardiography with intravenous agitated saline injection revealed patent foramen ovale with right to left shunt with immediate crossing of bubbles.Coronary angiography revealed normal coronaries. The patient refused intervention and he was maintained on warfarin treatment . Conclusion The clinical presentation of Ebstein’s anomaly is highly variable—depending on anatomic severity, haemodynamics ,and degree of interatrial shunting. The majority of patients have shunting through a secundum ASD or patent-foramen ovale. Paradoxical embolism maybe an indication for PFO/ ASD closure Abstract P843 Figure.

Double outlet right atrium (DORA) is a rare congenital heart disease in which the right atrium opens into both ventricles. The reduced leftward motion of the interventricular septum causes a malalignment between the atrial and the ventricular septum at the cardiac crux, which is the pathognomonic feature of this heart defect. We describe a case of significant exertional desaturation in an adult patient who was diagnosed with DORA, restrictive right ventricle, and anomalous tricuspid valve. Subsequently, the patient underwent one-and-a-half ventricular palliation.

Introduction: PDA represents one of the most frequently diagnosed type of congenital heart disease. Ductus arteriosus is a normal structure in foetal life, which permits shunting of oxygenated blood from the pulmonary artery into the aorta. Failure of sealing after birth is an abnormal condition and is called patent ductus arteriosus. In normal PDA, due to fact that systemic pressure is fivefold higher than pulmonary circulation, blood is shunted from the aorta into the pulmonary artery. In reverse PDA, pulmonary artery pressure does not drop after birth, and blood will be shunted form right to left. Aims: We want to evaluate clinical, haematological, ECG and echocardiographic changes in case of reverse PDA. Materials and Methods: Two-year old female Bichon Frise was referred to our clinic with signs of effort intolerance and dyspnoea for more than a year. ECG was performed in the right lateral recumbency using a digital device and echocardiography was done with Esaote MyLab40 Vet with a phased array transducer matched with the size of the dog (7.5 MHz). Results: We identified a dog with a good body score, quite alert and without any sign of illness. Haematological investigation underlined polycythaemia and very high PCV. The ECG revealed a normal sinus rhythm with a deep S wave, changes consistent with right ventricle enlargement.  Right atrial dilation and right ventricle hypertrophy were found on cardiac ultrasonography. The right ventricle free wall was hypertrophied and interventricular septum was flattened, changes consistent with increased pressure on the right side of the heart. The left heart was small. Positive diagnosis was done, performing “bubble study” and identification of contrast bubble within the abdominal aorta.   Conclusion: Reverse PDA is a rarely diagnosed congenital heart disease. Polycythaemia in young dogs could raise the suspicion of reverse PDA.  For positive diagnosis, echocardiography and bubble study are required. ECG is not a sensitive tool for diagnosis.
