Abstract Introduction Tricuspid valve duplication is an extremely rare condition and in most of the cases it is associated with other congenital cardiac malformations. Because of its rarity, the clinical presentation and the management are not defined yet. Clinical Case We report the case of an 18 y/o caucasian male, who was admitted to our Hospital in February 2018 for rapid atrial flutter not responsive to medical therapy (propanolol and digossin). He had a pre-natal diagnose of ventricular septum defect (VSD) and tricuspid straddling. At 1 year of age he underwent pulmonary artery bandage and one year later VSD closure was performed. Blood test showed sub-clinic hypothyroidism, probably related to previous amiodaron therapy. A transthoracic echocardiogram was obtained. The right atrium (RA) was severely dilated and the atrial septum dislocated towards left ventricle (LV); two right atrioventricular valves (tricuspid valves) were detected: the ‘true’ tricuspid opening was inside the right ventricle, and an ‘accessory‘ opening was located inside the LV and severely regurgitant into the RA; the mitral valve was morphologically and functionally normal; both ventricles were dilated with preserved systolic function; systolic pulmonary artery pressure was not detectable. A Cardiac Magnetic Resonance clearly delineated the anomaly. Atrial flutter radio frequency transcatheter ablation was succesfully performed before corrective surgery. The regurgitant accessory tricuspid orifice was closed with an heterologous pericardial patch and a right reduction atrioplasty was also done. The post-operative course was uneventful and only a mild paraseptal tricuspid jet with LV to RA shunt was present at post op echocardiography. After one year follow-up the patient remained asymptomatic, without arrhythmia recurrence. Conclusion DOTV is an extremely rare condition that could be responsible of severe tricuspid regurgitation. At the moment, there are not sufficient data to establish the correct timing for surgical intervention. In our case, the presence of severe tricuspid regurgitation, right atrium dilatation, biventricular overload and atrial flutter guided the clinical management and suggested surgical correction.

Peak Gradient

The study was conducted to record the various clinical, electrocardiographic, radiographic and echocardiographic changes in dogs with Pulmonary Hypertension (PH) due to mitral valve disease (MVD). Among the MVD, dogs 15.5 per cent, 8.7 per cent and 4.8 per cent had mild PH, moderate PH and severe PH respectively. A highly significant increase in tricuspid regurgitation velocity (greater than 2.5 mm/Hg), tricuspid regurgitation peak gradient (greater than 25 mm Hg), was recorded in dogs with mild, moderate and severe PH due to MVD when compared to their disease control. A highly significant increase in of MPA/Ao (greater than 0.8) ratio was recorded in dogs with various degree of PH (mild, moderate and severe) when compared with dogs without PH. According to the severity tricuspid regurgitation flow pattern in the right atrium during systole was recorded in all these dogs. In dogs with MVD, moderate to severe PH worsens outcome.

Abstract Funding Acknowledgements Financial support: French society of cardiovascular imaging. Background The respective strength of the different mechanisms that could lead to significant secondary TR occurrence remains debated. Purpose The main objective of our study was to characterize the determinants of tricuspid regurgitation (TR) severity in stable patients with preserved left ventricle ejection fractionand without significant left valvular heart disease. Patients were classified into 5 groups according to echocardiographic TR severity assessment: mild / moderate / severe / massive / torrential. Secondary objectives were to describe the evolution of the dimensions of the right cavities and the right ventricle (RV) function parameters according to the severity of the TR. Methods This is a prospective observational and multicentric study. Criteria for inclusion were: age ≥ 18 years; at least moderate TR; euvolemic status. We excluded patients with organic TR. All patients underwent standard trans-thoracic echocardiographyat distance from initial diagnosis and after stable optimized medical treatment. All exams were analysed in a Core Laboratory. Results 100 patients (12 presented mild TR, 31 moderate, 18 severe, 17 massive and 22 torrential) were enrolled and we used effective regurgitant orifice area (EROA) to quantify the severity of TR. To explain TR severity in multivariate analysis, right atrium (RA) indexed volume and tethering area were statistically significant (p < 0.001). For an increase of 10 mL/m2of RA volume, EROA increases by 4.2 mm2and for an increase of 0.1 cm2of tethering area, EROA increases by 2.2 mm2. The right heart dilation and the degree of restriction of tricuspid apparatus change significantly according to the severity of the TR (p < 0.001). RV function parameters did not differ significantly according to the degree of TR. Conclusion Early TA enlargement is present in secondary isolated TR. Then, increase in tethering area and RA indexed volume are associated with increase in TR severity. All right heart cavities dilate progressively without clear impact on RV-function parameters when TR increase. Factor determining increase in EROA coefficient SD p value RA volume (mL/m2) 0.42 0.09 < 0.001 Tethering area (cm2) 22.1 3.9 < 0.001 Multivariate linear regression model.

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.

Anatomic variants in the right atrium are under-recognized and under-reported phenomena in cardiac imaging. In the fetus, right atrium serves as a conduit for oxygenated blood to be delivered to the left heart bypassing the right ventricle and the nonfunctional lungs. The anatomy in the fetal right atrium is designed for such purposeful circulation. The right and left venous valves are prominent structures in the fetal heart that direct inferior vena caval flow towards the foramen ovale. These anatomic structures typically regress and the foramen ovale closes after birth. However, the venous valves can persist leading to a range of anatomic, physiological, and pathological consequences in the adult. We describe various presentations of persistent venous valves, focusing on the right venous valve in this illustrated multimodality imaging article.
