Rationale: The pathogenesis of bicuspid aortic valve (BAV)-associated aortopathy is poorly understood and no prognostic biomarker is currently available. Objective: We aimed to identify putative circulating biomarkers pathogenetically and prognostically linked to bicuspid aortopathy. Methods and Results: By RT-PCR, we evaluated gene expression variations (versus normal aorta) of transforming growth factor-beta1 (TGF-β1), connective tissue growth factor (CTGF), matrix metalloproteinase-2 (MMP-2), MMP-14, endoglin (ENG) and superoxide dismutase 3 (SOD3) in ascending aorta samples from 50 tricuspid and 70 BAV patients undergoing surgery for aortic stenosis (aorta diameter ≤45mm: BAVnon-dil or >45mm: BAVdil)...

OBJECTIVES: Patients with hypoplastic left heart syndrome or related malformations are predominantly treated with a 3-stage palliation. Anatomic or physiologic problems can lead to unplanned additional surgical or catheter interventions during single ventricle palliation. Changes in operative technique may have an impact on the reoperation rate. METHODS: Between 1997 and 2014, 317 Norwood procedures were performed at our centre. A retrospective single centre investigation was carried out concerning incidence, timing, indication and type of unplanned interstage cardiac reoperations and catheter interventions during follow-up of Norwood patients...

BACKGROUND AND OBJECTIVES: Although the regression of pulmonary hypertension (PH) in mitral stenosis (MS) has been studied over varying periods postintervention, corresponding studies on the cardiac chamber alterations after surgery are very limited. We sought to determine the degree of reversal of these and the clinical status in connection with that of pulmonary artery pressures (PAPs) in the early and late postoperative periods. METHODS: The preoperative, early, and 1-year postoperative data - functional class (FC), cardiothoracic ratio (CTR) in chest X-ray (CXR), and echocardiographically left atrium (LA), right atrium (RA), right ventricle (RV), left ventricle (LV), and pulmonary artery (PA) dimensions, PAP, tricuspid regurgitation (TR) - of 50 patients who had mitral valve replacement (MVR) for MS with PH were retrospectively analyzed for correlations with PAP (Pearson's), and their change (t-test), in relation to that in PAP...

OBJECTIVES: This study sought to investigate the impact of tricuspid regurgitation (TR) on right ventricular function after percutaneous pulmonary valve implantation (PPVI). BACKGROUND: PPVI provides a less invasive alternative to surgery in patients with right ventricular-to-pulmonary artery (RV-PA) conduit dysfunction. Recovery of the right ventricle has been described after PPVI for patients with pulmonary stenosis and for those with pulmonary regurgitation. Additional TR enforces RV dysfunction by supplemental volume overload...

INTRODUCTION: Rheumatic mitral stenosis is the most common Valvular Heart Disease encountered during pregnancy. Balloon Mitral Valvuloplasty (BMV) is one of the treatment option available if the symptoms are refractory to the medical management and the valve anatomy is suitable for balloon dilatation. BMV with Inoue balloon is the most common technique being followed worldwide. Over the wire BMV is a modified technique using Joseph Mitral Valvuloplasty (JOMIVA) balloon catheter which is being followed in certain centres...

Functional tricuspid regurgitation (FTR) is common, whether in association with mitral or aortic valve disease or presenting as an isolated valvular disease. Several studies have shown that TR is associated with poor patient outcomes, though a cause-and-effect relationship of TR to mortality has not been proven. Similarly the impact of surgical treatment of TR on outcomes needs well-controlled randomized trials that are under planning. The current professional society guidelines for treatment of TR are based on expert opinions with a level of evidence C for all indications...

Degenerative aortic stenosis is an acquired heart defect manifesting as progressive thickening and calcification of leaflets of originally normal tricuspid or congenital bicuspid aortic valve with development of orifice narrowing, left ventricular hypertrophy, and high risk of cardiovascular complications. In this review we present modern concepts of formation and progression of degenerative aortic stenosis and discuss optimal methods of management of this disease.

Tricuspid stenosis (TS) is an uncommon complication of ventricular pacemaker implantation. Mechanisms described by the literature are ventricular inflow obstruction by tricuspid vegetations (endocarditis) or multiple pacemaker leads and fibrosis secondary to mechanical trauma, accounting for perforation or laceration of the TV leaflets, or adherence between redundant loops and valve tissue. We present the case of iatrogenic tricuspid stenosis, observed in a 77-year-old man. Extrinsic tricuspid valve stenosis was detected by transthoracic echocardiography...

PURPOSE: An aortic valve stenosis is an abnormal narrowing of the aortic valve (AV). It impedes blood flow and is often quantified by the geometric orifice area of the AV (AVA) and the pressure drop (PD). Using the Bernoulli equation, a relation between the PD and the effective orifice area (EOA) represented by the area of the vena contracta (VC) downstream of the AV can be derived. We investigate the relation between the AVA and the EOA using patient anatomies derived from cardiac computed tomography (CT) angiography images and computational fluid dynamic (CFD) simulations...

Percutaneous transcatheter tricuspid balloon valvuloplasty (PTTBV) is an accepted treatment option for symptomatic severe native tricuspid valve stenosis, although surgical tricuspid valve replacement remains the treatment of choice. There have been few reports of successful PTTBV for bioprosthetic tricuspid valve stenosis. We present case reports of 3 patients from our hospital experience. Two of the 3 cases were successful, with lasting clinical improvement, whereas the 3rd patient failed to show a reduction in valve gradient...
