Aim. Study of heart function in the patients with CVD. Materials and methods. 46 patients with varicosity (VD) and 34 patients with post-thrombotic disease (PTD) were examined; the control group was represented by 15 healthy volunteers. The diagnosis was established using the CEAP basic classification. The study did not include patients with a diagnosed arterial hypertension, diabetes mellitus, chronic lung disease, significant hemodynamic heart defects, coronary heart disease. Ultrasound examination of the heart and veins of the lower extremities was performed on a Saote My Lab Alpha, Acuson Sequoia 512 apparatus. In addition to the standard protocol of heart ultrasound examination, the parameters of the right heart were calculated: sizes of the right ventricle (RV), right atrium, thickness of the anterior wall of the pancreas; to assess the ejection fraction (EF) of the pancreas the mobility of the lateral edge of the tricuspid ring was calculated, and the pressure on the tricuspid valve (TV) was measured. Diastolic ventricular function was studied by spectrograms of tricuspid and mitral blood flow. Results. Most of the indicators of cardiac activity in patients with VD were within normal limits, but a tendency to increase increasing of the right heart size was noted. In addition, the thickness of the interventricular septum and the right ventricle (RV) anterior wall was found to increase from 0.8 to 1.1 cm and from 0.3 to 0.5 cm, respectively, according clinical classes from C2 to C6 (CEAP). Eject fraction (EF) of both the RV and the left ventricle (LV) were also within normal limits, but with a tendency to decrease (67.8 % – C2, to 62 % – C6). The growth of the clinical class is followed by the increasing of percentage of non-restrictive blood flow through the tricuspid valve (TV). The restrictive type of blood flow in patients with VD had not been identified. Patients with PTD also showed a tendency to increase the right heart. However, whereas the size of the RV, as a rule, did not exceed 3.0 cm, the size of the right atrium was slightly higher than normal one in the clinical class C4 and C5.6. All the patients had EF of LV within normal limits, but it slightly decreased by the growth of class. Only patient classes C3 and C4 had EF of RV within the normal range. The 18 % of patient class C5.6 had EF lower than normal with value 48%. Diastolic dysfunction (DD) of the RV was detected in 73.3% of patients with class C3 and 100% with classes C4 and C5.6. Moreover, a restrictive type of blood flow through TV appeared from class C4 and the percentage increased up to 27.2% (class C5,6). Conclusions. DD of the RV was the main hemodynamic disorder.

Anomalous Pulmonary Venous Connection

Abstract Background: Partial anomalous pulmonary venous connection draining into the right atrium with an intact atrial septum is a very rare clinical entity in the adult population. Partial anomalous pulmonary venous connection must be suspected as a differential diagnosis when the cause of right heart enlargement and pulmonary artery hypertension is unknown.Case presentation: This study describes the surgical case of an isolated right partial anomalous pulmonary venous connection to the right atrium in a 68-year-old woman, who underwent tricuspid ring annuloplasty and right-sided maze procedure simultaneously. She had complaints of gradually progressing dyspnea on exertion. However, a diagnosis could not be established despite consultations at multiple hospitals for over a year. Right heart catheterization revealed severe pulmonary artery hypertension with a mean pulmonary artery pressure of 46 mmHg, step-up phenomenon of oxygen saturation at the mid-level of the right atrium with a pulmonary-to-systemic blood flow ratio of 2.4, and a pulmonary vascular resistance of 3.1 Wood Units. In addition, it was mandatory to comprehensively utilize valuable imaging modalities, such as transthoracic echocardiography, transesophageal echocardiography, and multidetector computed tomography angiography for the accurate diagnosis and efficient surgical planning of this partial anomalous pulmonary venous connection. As medical treatment with pulmonary artery vasodilator therapy did not improve her symptoms, she underwent surgical repair. An atrial septal defect was created surgically with a curvilinear tongue-shaped cut. The right anomalous pulmonary veins were rerouted through the surgically created atrial septal defect into the left atrium with a baffle comprised of the interatrial septum flap, kept in continuity with the anterior margin and sutured while mobilizing the enlarged right atrium. The patient had an uneventful postoperative course and remains asymptomatic. Conclusions: The described surgical technique could be considered an effective alternative for patients undergoing surgical repair for a partial anomalous pulmonary venous connection isolated to the right atrium. The indication for surgery must be judged on a case-by-case basis in these patients with prevalent systemic-to-pulmonary shunting.

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.

Since the pioneering work of Fontan and Baudet, who suggested that a dysfunctional right ventricle could be bypassed by connecting the pulmonary arteries directly to the right atrium in the so-called atriopulmonary anastomosis, much experience has been gained in the field of the functionally univentricular circulation. In view of the continuing need to optimize the fluid dynamics of the connection, research on this topic remains very active. In particular, it is relevant to consider the power dissipated during flow across a connection of this type, due to the low level of the pressure head available for perfusion. The flow to the lungs in this setting is driven only by the low pressure in the caval veins, thus making it essential to minimize the losses of energy in the connection between the terminal part of the venous system and the pulmonary arteries.

A method of pulmonary artery (PA) catheterization in the closed-chest rat is described. This catheterization is best accomplished with teflon catheters having a (shepherd's crook) tip. Catheter preparation is detailed. The functional advantages of such a PA catheter are: 1) the tip can remain free within the right ventricle (RV) without becoming occluded by contact with the ventricular wall, and 2) entry into the PA is simple and reproducible. Dual catheterization of the RVand PA produced only a small systolic gradient (3 mmHg) across the pulmonic valve. We concluded that the PA catheter does not unduly obstruct blood flow through this valve.

Abstract Introduction Idiopathic aneurysmal dilatations of the right atrium are rare anomalies. It can be diagnosed at any time between foetal and adult life. This exceptional condition can be confused with other conditions that involve enlargement of right atrium. We report a clinical case of a symptomatic adult who was diagnosed with giant right atrium aneurysm. Case report An 83-year-old female presented with complaints of fatigue, paroxysmal nocturnal dyspnoea, exertional dyspnoea, orthopnoea and cough since last week. There were no history of syncope, convulsions or evidence of thromboembolism. There were a medical history of diverticulosis and atrial fibrillation (warfarin therapy). The principal findings on physical examination included holosystolic murmur at the left middle sternal border, pulmonary rales, jugular venous distension, enlarged liver and peripheral oedema. An electrocardiogram showed an atrial fibrillation with a controlled heart rate response, right axis deviation, right bundle-branch block. A chest radiography posteroanterior view showed a markedly enlarged cardiac silhouette, increased pulmonary vascular congestion, and bilateral pleural effusions. Computed tomography (CT) scan showed aneurysmal dilated right atrium communicating with right ventricle. Right ventricle (RV) and RV outflow tract were dilated with normal pulmonary arteries. Two-dimensional transthoracic echocardiography revealed aneurysmal dilated right atrium measuring 398mL/m2. The tricuspid valve was no displaced. There was severe tricuspid regurgitation and no stenosis. The right atrium was kinetic without any intracavitary thrombus. The intertrial and interventricular septa were intact. The right ventricle and outflow tract were mildly dilated with preserved systolic function. The left atrium and left ventricle were normal. The patient was admitted to the cardiology department with the diagnosis of right heart failure. Conclusion Aneurysm of right atrium is an uncommon condition. It is diagnosed as a disproportionately enlarged right atrium compared to the other cardiac chambers in the absence of other cardiac or hemodynamic abnormalities and must be distinguished from other anomalies causing structural pathology of the right atrium. Approximately, one-half of the patients have no symptoms. Others presented with arrhythmia, palpitations, chest pain, shortness of breath, and fatigue. The major rhythm abnormality is atrial fibrillation or atrial flutter. Our patient presented with symptoms of right heart failure and atrial fibrillation. The right enlargement is usually associated with tricuspid annular dilatation responsible for functional regurgitation, which can be severe in some cases. The diagnosis of right atrium malformation can be established by echocardiography, CT or magnetic resonance imaging. Literature reports various ways to manage these patients. Treatment ranges from conservative to surgical resection specially in the presence of arrhythmias. Abstract P1242 Figure. Aneurysm of right atrium

Abstract A 38y. old woman was admitted to a Cardiology Department due to increased exertional dyspnea and decreased exercise tolerance. Echocardiography performed in an outpatient setting has found a substantial enlargement of the right ventricle and severe tricuspid regurgitation. Physical examination significantly enlarged liver, pulsation of jugular veins and numerous scars in the pits elbow. ECG sinus rhythm 85 / min. Right axis deviation. LPH. Hypertrophy of the right atrium. QS in V1-V4. Transthoracic and Transesophageal Echocardiography (TTE,TEE) EF 64%, a significant increase in a right heart chambers (RVDD 4.1 cm, severe tricuspid regurgitation with completely disappearing of tricuspid valve ( only part of septal leaflet was present, which was a consequence of pressure equalization between the right atrium and the right ventricle). In addition, it revealed the structure connected with the pulmonary valve leaflet and moving between the right ventricular outflow tract and pulmonary trunk (most probably healed vegetation, 1.2 x 0.5 cm ). Computed tomography (CT) confirmed the significant enlargement of right heart chambers (EDV 335 ml, ESV 143 ml, SV 192 ml, EF ∼ 58%) with displacement of interatrial septum to the left and the flattening of the interventricular septum . Complete destruction of the tricuspid valve leaflets, with the remaining residual part of septal leaflet was observed. The pulmonary valve was connected mobile irregular structure 2,5 cm x 0,5 cm. Laboratory tests revealed a history of cytomegalovirus infection (p / body IgG> 500,000U / ml). Other tests (HIV, hepatitis B, reaction W-R) - were negative. There was no laboratory and clinical signs of active infection at present. Patient demanded to be discharged from the hospital and refused operation. DISCUSSION Echocardiography did not confirm diagnosis of pulmonary hypertension. D-dimer values of 396 ng / ml (normal <500 ng / ml) excluded suspicion of pulmonary embolism. Left ventricular ejection fraction was normal (EF ∼ 64%), BNP reached the value of 153 pg / ml (normal 0-100pg / ml). This case deserves attention because it documents severe right heart endocarditis by the person using drugs intravenously with an extremely rare takeover of both right heart valves and septic pulmonary embolism. Despite such a large morphological change in the heart of a patient remains in a relatively good clinical condition (NYHA class II/ III). The observed structure of the pulmonary trunk should be considered as healed vegetation. In the absence of consent to the surgery the patient is still treated pharmacologically. Abstract P855 Figure.

The aim of this study was to identify correlations between electrocardiographic and echocardiographic changes in patients with silicosis prior to the occurrence of chronic pulmonary heart disease. We conducted a prospective, descriptive, analytical study, in which we included a group of 67 patients consecutively admitted to the Health Promotion and Occupational Medicine Clinic between December 2016 and January 2018, aged 47 to 78 years.There was a biochemical and electrocardiographic evaluation for each patient as well as a right ventricle echocardiographic evaluation (diameters, volumes, function). A control group, including 25 patients with benign minor diseases that required a cardiologist consultation, was also used. From the electrocardiographic point of view, slight changes were observed regarding the waves of electrical activity of the right ventricle. Taking into account the degree of ventilatory dysfunction (depending on FEV1), changes in right heart echocardiographic parameters were identified. Thus, in what the most important right ventricular parameters, including the tricuspid annular plane systolic excursion (TAPSE) or the RV index of myocardial performance (RVMPI) were concerned, values at the upper limit of normality were recorded in most patients with moderate and severe ventilatory dysfunction. Values of echocardiographic parameters of the right heart at the upper limit of normality, correlated with the degree of ventilatory dysfunction, are early markers for cardiovascular damage in patients with pulmonary silicosis prior to the occurrence of chronic pulmonary heart disease also known ascor pulmonale.

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.
