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.

AbstractObjectivesTo define the utility of transesophageal echocardiography in predicting the likelihood of a successful procedure and residual shunting in patients undergoing transcatheter closure of defects within the oval fossa using the CardioSEAL® device.BackgroundTransesophageal echocardiography is used to monitor transcatheter closure of interatrial defects within the the oval fossa, but predictors of successful closure and residual shunting have yet to be determined.MethodsWe reviewed transesophageal echocardiograms obtained from 26 consecutive patients undergoing attempted transcatheter closure of interatrial defects within the oval fossa between January, 1997 and May, 1998. Assessment of the atrial septum, the septal defect, and the rims of the oval fossa bordering the defect was performed in 3 planes: longitudinal, 4- chamber, and basal short-axis.ResultsClosure proved successful in 24 patients (92%). The defect was significantly larger, and the anterosuperior rim of the defect smaller, in the 2 patients in whom occlusion was not successful. Residual shunting 24 hrs after closure was detected in 14 patients. Significant predictors of leakage included smaller posterior and superior rims, a larger shunt prior to closure, and herniation of a one left atrial arm of the device into the right atrium. In all cases, the sites of leakage were the superior rim of the defect at the superior cavo-atrial junction, and the anterosuperior rim behind the aortic root. Herniation of a left atrial arm into the right atrium was seen in 7 patients (29%). In all, it was the anterosuperior arm which herniated Doppler color flow was suboptimal in detecting residual leaks, and was enhanced substantially with the use of contrast echocardiography.ConclusionsTransesophageal echocardiography allows excellent assessment of the oval fossa and deficiencies of its floor in all of their dimensions. It is an important tool for guiding the deployment of the occlusion device in patients undergoing attempted transcatheter closure of defects within the fossa. Contrast echocardiography should be used for optimal detection of residual shunting.

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.
