INTRODUCTION: Liposarcoma of the heart and stomach is rare. PRESENTAION OF CASE: We report a case of liposarcoma in both organs with dedifferentiated histology. A patient was referred to our hospital with anorexia and weight loss. Upper gastrointestinal tract endoscopy revealed 5-10-mm elevated lesions, and echocardiography and computed tomography showed tumorous lesions in the left atrium. Tumor resection and mitral valve replacement were performed, and biopsy was performed for the gastric tumor...

Mitral regurgitation (MR) is frequent and associated with increased mortality and morbidity when severe. It may be caused by intrinsic valvular disease (primary MR) or ventricular deformation (secondary MR). Imaging has a critical role to document the severity, mechanism, and impact of MR on heart function as selected patients with MR may benefit from surgery whereas other will not. In patients planned for a surgical intervention, imaging is also important to select candidates for mitral valve (MV) repair over replacement and to predict surgical success...

Right ventricular (RV) dysfunction is generally evaluated using analyses of tricuspid annular motion. However, it represents only one aspect of RV performance. Whether measuring pulmonary annular motion velocity could serve as a novel way to evaluate global RV and/or RV outflow tract (RVOT) performance in pediatric congenital heart disease (CHD) patients with surgically repaired RVOT was evaluated. In this prospective study, tissue Doppler-derived pulmonary annular motion velocity was measured in children (aged 2-5 years) with RVOT reconstruction (RVOTR group, n = 48) and age-matched healthy children (Control, n = 60)...

OBJECTIVES: The objective of this study was to determine the safety and efficacy of intracardiac echocardiography (ICE) to guide percutaneous paravalvular leak (PVL) closure. BACKGROUND: PVL following surgical valve replacement occurs in 2%-15% of patients. Percutaneous treatment is an accepted management strategy in patients deemed to be too high risk for redo surgery. This is most commonly performed with transesophageal (TOE) guidance requiring general anesthesia that both potentially further increase the risk of intervention...

Pulmonary valve replacement via surgical implantation of a bioprosthetic valve (BPV) is a well-established treatment for patients with dysfunctional RV outflow tracts. BPVs are prone to structural deterioration, and will eventually require replacement. Recently, percutaneous valve-in-valve (VIV) placement of transcatheter valves has established itself as a safe and effective alternative to surgical revision. Unfortunately, VIV therapy is inherently limited by the inner diameter of the BPV, which restricts the number of eligible patients...

In patients with mechanical aortic and mitral valve prosthesis, left ventricular (LV) endocardial ablation via retrograde transaortic or antegrade transmitral approach carry high risk of catheter entrapment and death. In such cases, ablation can be performed via ventricular transseptal or transapical approach. Transapical approach, with the ease of catheter maneuverability and better endocardial contact, may be performed surgically or percutaneously. In this case report, we describe a patient with both aortic and mitral mechanical prosthesis who underwent ventricular tachycardia (VT) ablation via percutaneous transapical endocardial approach with the use of closure device...

BACKGROUND: The projected aortic valve area (AVAproj) at a normal transvalvular flow rate using dobutamine is helpful to determine the actual severity of aortic stenosis (AS) and to predict risk of adverse events in low-gradient AS cases with unclear surgical indication. Our study aimed to identify the independent and incremental value of preload stress echocardiography-derived AVAproj to predict outcomes in patients with preserved ejection fraction and low-gradient AS. METHODS AND RESULTS: We prospectively performed echocardiographic studies in 79 patients with low-gradient AS (age, 77±7 years; 30% men) with preload stress echocardiography using leg positive pressure...

In the last decade, transcatheter aortic valve implantation (TAVI), a disruptive technology, has revolutionized the therapy of symptomatic severe aortic stenosis, and current guidelines state that the recommendations for TAVI and surgical aortic valve replacement (SAVR) are equivalent in patients at high-risk. Increased operator experience, technical advances in the new generation of transcatheter heart valves (THV) and excellent TAVI results in recently published randomized controlled trials have led to the expansion of TAVI indication as an alternative to SAVR in intermediate-risk subjects, given appropriate patient selection...

BACKGROUND: Right ventricular dysfunction in patients with tetralogy of Fallot and significant pulmonary regurgitation may lead to systolic dysfunction of the left ventricle due to altered ventricular interaction. We were interested in determining whether chronic pulmonary regurgitation affects the preload of the left ventricle. In addition, we wanted to study whether severe chronic pulmonary regurgitation would alter the preload of the left ventricle when compared with patients having preserved pulmonary valve annulus...

The remodeling and the reimplantation procedures were described more than 25 years ago with the aim of sparing, otherwise normal aortic valve in the presence of a root aneurysm. Because of its ability to reconstruct the sinuses of Valsalva, the remodeling procedure was considered to be more physiological than the reimplantation. However, because the remodeling lacked annular stabilization, the long-term stability of the procedure was questioned. However, through the years, both procedures have been significantly improved, so that is now possible to perform a reimplantation procedure with neo-sinuses reconstruction or a remodeling procedure with annular stabilization...
