OBJECTIVES: The authors used transthoracic 3-dimensional transthoracic echocardiography (3DE) to characterize tricuspid annulus (TA) geometry and dynamics in healthy volunteers. BACKGROUND: Accurate sizing of the TA is essential for planning tricuspid annuloplasty and for implantation of new percutaneous tricuspid devices. METHODS: 3DE of the TA from 209 healthy volunteers was analyzed using custom software to measure TA area, perimeter, circularity, and dimensions at end diastole (equals tricuspid valve closure), mid-systole, end systole, and late diastole...

We sought to describe the acute results and short- to medium-term durability of transcatheter tricuspid valve-in-valve (TVIV) implantation within surgical bioprostheses among patients with Ebstein anomaly (EA). Cases were identified from a voluntary, multicenter, international registry of 29 institutions that perform TVIV. Demographic, clinical, procedural, and follow-up data were analyzed. Eighty-one patients with EA underwent TVIV from 2008 to 2016. Thirty-four patients (42%) were New York Heart Association (NYHA) class 3/4 at time of TVIV...

Polyamines are cationic molecules synthesized via a highly regulated pathway, obtained from the diet or produced by the gut microbiota. They are involved in general molecular and cellular phenomena that play a role also in vascular disease. Bicuspid aortic valve (BAV) is a congenital malformation associated to a greater risk of thoracic ascending aorta (TAA) aneurysm, whose pathogenesis is not yet well understood. We focused on differential analysis of key members of polyamine pathway and on polyamine concentration in non-dilated TAA samples from patients with either stenotic tricuspid aortic valve (TAV) or BAV (diameter ≤ 45 mm), vs...

We present the case of a 69-year-old patient who was referred to the Department of Echocardiography for surgical treatment of severe tricuspid valve regurgitation (TVR) with advanced congestive heart failure. In 2013 the patient underwent unsuccessful percutaneous ablation for permanent atrial fibrillation. In 2015, following numerous episodes of atrial fibrillation and congestive heart failure with left pleural effusion, the patient was admitted to another center. A transthoracic echocardiogram showed severe TVR and moderate precapillary pulmonary hypertension, confirmed at right cardiac catheterization...

Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV procedures for failing mitral bioprosthetic valves, 1 transfemoral procedure for failing pulmonary valve and 2 transfemoral ViV implantation for failing tricuspid bioprosthetic valves...

Totally thoracosopic mitral valve replacement (MVR) has been applied to mitral stenosis for many years. Three working ports are usually necessary, among which the longest port ranges from 6 to 8 cm. This study aimed to determine the safety and feasibility of the two-incision totally thoracoscopic approach for MVR, with the longest incision of 3 cm.From January 2014 to February 2016, 90 patients with mitral valve stenosis were retrospectively analyzed. Thirty-six (40%) patients were included in the two-incision group and 54 patients were operated on using the sternotomy approach...

Aims: Pulmonary hypertension (PH) is common in severe symptomatic left-sided valvular disease, particularly in aging populations. Inconsistent results have been reported concerning the association between PH and adverse outcomes after aortic valve replacement for aortic stenosis (AS). We therefore retrospectively investigated the prognostic significance of PH using peak tricuspid regurgitation velocity (TRV), as defined by the current European Society of Cardiology (ESC)/European Respiratory Society (ERS) guidelines, in a large cohort of patients with severe AS...

A 83-year-old woman, suffering from rapidly worsening dyspnea and weight gain from a week ago, was referred for evaluation and treatment of cardiac tumor in the right atrium. Echocardiography and enhanced computed tomography revealed a large tumor, more than 6 cm, occupying the right atrium and blocking the tricuspid valve inflow. Electrocardiogram showed bradycardiac atrial fibrillation. We performed partial resection with cardiopulmonary bypass, in order to improve hemodynamics and to make a definite diagnosis...

There has not been much progress in the development of transcatheter tricuspid valves to treat tricuspid regurgitation because of the difficulty in anchoring a stented valve onto the complex tricuspid annulus. Hence, the concept of heterotopic implantation of the transcatheter tricuspid valve onto the cavo-atrial junction was proposed. However, to date there has been no detailed in vitro investigation of the hemodynamic performance of this new device. The study utilises both 2-D and 3-D particle image velocimetry (PIV) to interrogate the flow patterns in the vicinity of the extra-cardiac tricuspid valves in an in vitro physiological flow loop, specifically at four measurement locations in the cavo-atrial anatomy...

BACKGROUND: Pulmonary valve replacement is becoming the most frequent congenital heart surgery performed on adolescents and young adults. Numerous surgical options are available, including autologous pericardium, mechanical valves, allografts, and bioprosthetic valves. Each option has limitations with durability and freedom from reintervention for stenosis or insufficiency, particularly in the pediatric population. The purpose of this study was to analyze our uniquely designed, expanded polytetrafluoroethylene (ePTFE) valved conduit (VC) for right ventricular outflow tract reconstruction...

Atrial septal defects (ASDs) are common immediately after percutaneous mitral commissurotomy (PMC). They are usually small, hemodynamically insignificant, and tend to decrease or disappear within 6 to 12 months. Herein, a case is described of persistent ASD in a patient with mitral valve stenosis who had undergone successful PMC three years previously. The patient had signs and symptoms of right heart failure and severe tricuspid regurgitation (TR) with borderline right ventricular systolic function on echocardiography, in addition to the ASD...
