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 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.

Main funding source(s): Ministry of Science and Technology, Executive Yuan, Taiwan Background Tricuspid regurgitation (TR) were traditionally classified as primary and secondary TR. Recently a new category of TR was developed and named as idiopathic TR. However, diagnosis and characteristics of idiopathic TR were not consisted. We tried to identify idiopathic TR by a new systemic approach and studied its characteristics. Methods 207 consecutive patients (mean age 71.2 ± 14.7 years, 40.6% male) identified as significant TR (moderate and severe) by echocardiography were recruited. We classified TR by a new systemic approach. The classification process started from identified primary TR, then pacemaker related TR, left heart disease related TR, congenital heart related TR, right ventricular (RV) myopathy, pulmonary hypertension and, finally idiopathic TR step by step. Results There were 29 (14%) primary TR, 18 (8.7%) pacemaker related, 81 (39.1 %) left heart diseases, 6 (2.9%) congenital heart diseases, 3 (1.4%) RV myopathy, 27 (13%) pulmonary hypertension, and 43 (20.8%) idiopathic TR. Mean age of idiopathic TR was 72.9 ± 11.4 years and 39.5% was male which were not different from other groups. Atrial fibrillation was presented highest in patients with pacemaker related TR (77.8%) and left heart disease (55.6%), lowest in primary TR (24.1%) and pulmonary HT (25.9%), and modest in idiopathic TR (44.2%). Among the echocardiographic characteristics of right heart measurements, idiopathic TR had lowest TR maximal velocity (3.0 ± 0.3 m/s), pulmonary (41.2 ± 8.7 mmHg) and right atrium pressure (5.3 ± 0.3 mmHg; all p <0.001). Idiopathic TR had smallest RV wall thickness (4.5 ± 1.4 mm; p = 0.008), tricuspid annulus diameter (3.2 ± 0.7 cm; p = 0.001), and right atrial area (18.9 ± 8.4 cm2; p <0.001). RV function represented as tricuspid annulus velocity S’ (12.8 ± 3.3 cm/s; p = 0.011) and RV fractional area change FAC (42.6 ± 16.0 %; p <0.001) were best in idiopathic TR. RV dysfunction (FAC < 35%) was lowest (14%) in idiopathic TR. Conclusions Idiopathic TR had better RV function then other types of TR. Idiopathic TR can be regarded as a unique disease category in studying TR.

We herein present a case of infective endocarditis of the mitral valve and a paravalvular abscess around the tricuspid valve. Preoperative blood culture confirmed the presence of pathogenic diphtheroids. During the operation, an unexpected infection of the free wall of the right atrium (RA) near the tricuspid annulus was found. We harvested the left atrial appendage (LAA) en bloc. After resection of the infected and abnormal tissues, the resected LAA was used to reconstruct the RA. The infected mitral valve was replaced with a mechanical valve without any accident. Postoperative echocardiography showed that the RA had a supple shape, with no kinking.

Introduction. A comorbid patient with the chronic obstructive pulmonary disease (COPD) in combination with cardiovascular diseases (CHD) has a poor prognosis due to the early progression of the pulmonary hypertension (PH). The study surveyed an opportunity of the PH detection using an active PH verification strategy in outpatients with COPD and stable angina pectoris.Goal. To evaluate the frequency of РH in patients with mild and moderate COPD in combination with CHD and the possibility of using the echocardiographic criterion «right atrial area» to prove РH.Materials and methods. The study included 52 outpatient patients with an average age of 62.8 ± 8.14 years. A comprehensive assessment of the Borg dyspnea scale, echocardiography, pulse oximetry at rest and after the 6-minute walk test (6MWT) were carried out. Two groups of patients were compared depending on the development of РH after T6MX.Results and discussion. It was shown that in patients with COPD (GOLD I-II) and angina pectoris, PH was initially detected in 3.3% of cases, and after the 6MWT in 63.3% of patients. In this group, after T6MX, an increase in pulmonary artery pressure was determined from 18.5 ± 10.6 mmHg to 41.2 ± 12.5 mmHg (p < 0.05). After physical activity with increased pressure in the pulmonary artery, there was a significant increase in the area of the right atrium. Only 1/3 of patients with PH had hypoxemia after the 6MWT.Conclusions. The T6M test makes it possible to detect РH in more than half of patients with COPD (GOLD I-II) and CHD in an outpatient setting. An enlargement in the area of the right atrium according to echocardiography, along with the other indicators of morphological and functional changes in the right heart, can be an additional diagnostic criterion for PH in comorbid patients with COPD and cardiovascular diseases.
