MicroRNAs are able to modulate gene expression in a range of diseases. We focused on microRNAs as potential contributors to the pathogenesis of ascending aorta (AA) dilatation in patients with stenotic tricuspid (TAV) or bicuspid aortic valve (BAV). Aortic specimens were collected from the 'concavity' and the 'convexity' of mildly dilated AAs and of normal AAs from heart transplant donors. Aortic RNA was analyzed through PCR arrays, profiling the expression of 84 microRNAs involved in cardiovascular disease...

Surgical intervention for severe tricuspid regurgitation secondary to remote infective endocarditis has been infrequent, especially in patients also infected with the human immunodeficiency virus (HIV). We describe the case of a 62-year-old HIV-positive man, with a 24-year history of endocarditis caused by intravenous heroin use, who presented with severe tricuspid regurgitation. The patient was initially asymptomatic, was taking antiretroviral medications, and had a satisfactory CD4 count and an undetectable viral load, so we decided to manage the regurgitation conservatively...

Lymphoma can involve any organ or tissue that contains lymphoid tissue and the heart is no exception. A few prior case reports have described lymphoma encasing a coronary artery or involving one or more cardiac valves. We present a rare case of diffuse large B-cell lymphoma (DLBCL) involving the tricuspid valve and right coronary artery diagnosed on coronary CT angiography. The clinical and imaging characteristics of cardiac lymphoma are discussed.

Pulmonary pulse wave transit time (pPTT), defined as the time for the systolic pressure pulse wave to travel from the pulmonary valve to the pulmonary veins, has been reported to be reduced in pulmonary arterial hypertension (PAH); however, the underlying mechanism of reduced pPTT is unknown. Here, we investigate the hypothesis that abbreviated pPTT in PAH results from impaired right ventricular-pulmonary artery (RV-PA) coupling. We quantified pPTT using pulsed-wave Doppler ultrasound from 10 healthy age- and sex-matched controls and 36 patients with PAH...

Pulmonary hypertension (PH) and right ventricular function are the focus of cardiovascular effects of bronchopulmonary dysplasia (BPD). We assessed cardiac indexes reflecting systemic afterload and pulmonary venous back pressure as pathophysiologic factors. Cardiac parameters were measured by conventional echocardiography in 20 preterm infants with severe BPD and compared with those of 10 preterm infants with no BPD and 20 healthy term infants. In infants with severe BPD, PH was noted in 5 (25%) by tricuspid regurgitation Doppler jet ≥2...

AIMS: The aim of this study was to investigate the procedural feasibility and short-term durability of the transcatheter tricuspid valve edge-to-edge repair technique in highly symptomatic patients with severe tricuspid regurgitation (TR). METHODS AND RESULTS: Eighteen consecutive patients suffering from severe right-sided heart failure (NYHA Class III-IV), primarily due to moderate to severe tricuspid regurgitation, were included in the study. Applying a modified steering technique for the clip delivery system, six patients were treated for isolated severe TR, while 12 patients were treated for moderate to severe TR and concomitant severe mitral regurgitation...

AIMS: We sought to assess the impact of TR severity on patient outcome in a collective with relevant mitral regurgitation undergoing MitraClip implantation. METHODS AND RESULTS: From 08/2010-07/2013, 766 patients (age 75.3±8.5 years, 61% male gender, median EuroSCORE 24.3%±18.4) were prospectively enrolled in the TRAMI registry and stratified by echocardiography in no/mild, moderate and severe TR. Overall, the mean of implanted MitraClips was higher in patients with severe TR but increasing TR severity was not associated with procedural success...

INTRO: The optimal management of patients with congenitally-corrected transposition of the great arteries (ccTGA) is unclear. The goal of this study was to compare the outcomes in patients with ccTGA undergoing different management strategies. METHODS: Patients with ccTGA believed suitable for biventricular circulation treated in 1995-2016 were included. The cohort was divided into four groups: systemic right ventricle (RV) (patients without surgical intervention or with a classic repair), anatomic repair, Fontan palliation, and patients only receiving a pulmonary artery band (PAB) or a shunt...

BACKGROUND: Two-dimensional (2D) echocardiography is one of the most feasible, noninvasive methods for assessing the aortic diameter and biomechanical changes. We studied possible interfaces between noninvasive biomechanical and speckle-tracking (ST) echocardiographic data from dilated aortas. METHODS: Altogether, 44 patients with dilative pathology of ascending aorta (DPAA) were compared with subjects without ascending aortic dilation (diameter <40 mm). DPAA patients formed two groups based on diameter size: group 1, ≤45 mm diameter; group 2, >45 mm...

Quadricuspid aortic valve (QAV) is a rare congenital heart disease. The functional status of QAV is predominantly a pure aortic regurgitation. Clinical manifestations of patients with a QAV depend on the functional status of the QAV and the associated disorders. Significant valvular regurgitation and (or) stenosis is often present with subsequent operation performed at the fifth to sixth decade of life. The functional status of QAV is predominantly regurgitant; whereas pure stenotic QAV can be as few as in only 0...

AIMS: Permanent pacemaker placement (PPM) is often required after valvular surgery and is especially common following tricuspid valve surgery [tricuspid valve repair or replacement (TVR)]. Literature suggests that surgical intervention for isolated tricuspid valve disease is becoming more prevalent. Predictors of PPM dependency following TVR are currently unknown and would be clinically useful from a prognostication standpoint. METHODS AND RESULTS: We conducted a multicentre, retrospective study to assess perioperative factors of TVR that predispose to PPM placement and long-term PPM dependency from 2008 to 2014...

BACKGROUND: Functional tricuspid regurgitation (TR) with a structurally normal tricuspid valve (TV) may occur secondary to chronic atrial fibrillation (AF). However, the clinical and echocardiographic differences according to functional TR subtypes are unclear. Therefore, characterization of functional TR because of chronic AF (AF-TR) remains undetermined. METHODS AND RESULTS: To investigate the prevalence of AF-TR, 437 patients with moderate to severe TR underwent 3-dimensional (3D) transesophageal echocardiography...

A 40-year-old woman was admitted due to dyspnea and fever. Transthoracic echocardiography revealed signs of right heart volume overload and vegetations on the tricuspid valve with insufficiency. Transesophageal echocardiography showed a sinus venosus defect (SVD) with significant left-to-right shunt. Computed tomography scanning was primarily performed to rule out pulmonary embolism; however, it showed interatrial communication. Due to the concomitant tricuspid insufficiency with additional volume overload, the diagnosis of SVD was more challenging...

A 32-year-old pregnant woman, diagnosed with Behçet's disease 6 months earlier, presented with recent mild hemoptysis and exertional dyspnea. Transthoracic echocardiography showed an enlarged dysfunctional right ventricle. A large hypoechoic triangular-shaped mass was seen attached to the inner right ventricular wall, filling the cavity. No change in the size of the mass was noted after anticoagulant administration, and right heart failure progressed. Surgery was performed to remove the mass and repair the tricuspid valve...

PURPOSE OF REVIEW: Tricuspid valve disease has received much less attention in terms of intervention. The main reason for this is the widely held belief that treatment of left-sided valve disease leads to resolution of functional tricuspid regurgitation. Recent data show that tricuspid regurgitation is not benign and that many patients will benefit from intervention at the time of left-sided valve surgery, or in isolated tricuspid disease. This review describes the latest surgical and interventional options and strategies...

BACKGROUND: Annuloplasty bands and rings are widely used for repairing functional tricuspid regurgitation (FTR). However, the question regarding which is the ideal annuloplasty device remains unclear. The aim of this study was to compare the efficacy and mid-term durability of tricuspid ring annuloplasty for FTR secondary to rheumatic mitral valve disease using flexible Cosgrove-Edwards band and the rigid Edwards MC3 ring (Edwards Lifesciences, LLC, Irvine, CA, USA). METHODS: We retrospectively collected the clinical data of those who underwent mitral valve replacement (MVR) in concomitant with tricuspid ring annuloplasty from 2009 to 2013...
