BACKGROUND: Stress echocardiography (SE) has an established role in evidence-based guidelines, but recently its breadth and variety of applications have extended well beyond coronary artery disease (CAD). We lack a prospective research study of SE applications, in and beyond CAD, also considering a variety of signs in addition to regional wall motion abnormalities. METHODS: In a prospective, multicenter, international, observational study design, > 100 certified high-volume SE labs (initially from Italy, Brazil, Hungary, and Serbia) will be networked with an organized system of clinical, laboratory and imaging data collection at the time of physical or pharmacological SE, with structured follow-up information...

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...

The current trend to treat hypotension in critically ill patients is to place a greater emphasis on inotropic support and less on fluid resuscitation in order to limit the potential harm from fluid overload. This combination may trigger left ventricular outflow tract obstruction (LVOTO) in susceptible patients. Although LVOTO is classically described in patients with hypertrophic cardiomyopathy it has been reported in other conditions including septic shock, apical ballooning syndrome, myocardial infarction, respiratory failure, and post valvular surgery...

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: Structural valve deterioration is the major cause of bioprosthesis failure and is increasing over time. We present an overview of incidence, mechanisms, predictors, clinical impact, and management of bioprosthetic valve structural degeneration. RECENT FINDINGS: Early degeneration caused by calcification and destruction of connective tissue of the prosthesis is controlled by multiple mechanisms, from mechanical stress to infiltration of lipids and inflammatory cells, and activation of the immune system...

The recent technical advances allow the use in practice of three-dimensional echocardiography in children especially through the new high frequency matrix probe. It is difficult or even impossible to hold breathing during children' acquisition so to avoid motion full volume artifact, one beat and live 3D modes are suitable. 3D echocardiography is more accurate than 2D to assess the size, location, and relationship with surrounding structures of atrial and ventricular septal defects and thus helps in the therapeutic decision...

Antiphospholipid syndrome (APS) is an autoimmune hypercoagulable disorder characterized by thrombophilia, vascular thrombosis, and recurrent abortions associated with persistent antiphospholipid antibodies. APS may exist in its primary form, or more commonly is found to be associated with variety of rheumatic disorders, such as systemic lupus erythematosus. Cardiac involvement is not an uncommon complication in primary antiphospholipid patients. Libman-Sacks lesions are typically small, sessile, and wart-like, varying in size from 1-4 mm...

Cardiac tissue engineering using biomaterials with or without combination of stem cell therapy offers a new option for repairing infarcted heart. However, the bioactivity of biomaterials remains to be optimized because currently available biomaterials do not mimic the biochemical components as well as the structural properties of native myocardial extracellular matrix. Here we hypothesized that human heart valve-derived scaffold (hHVS), as a clinically relevant novel biomaterial, may provide the proper microenvironment of native myocardial extracellular matrix for cardiac repair...

This study presents the in vitro hydrodynamic assessment of the TRISKELE, a new system suitable for transcatheter aortic valve implantation (TAVI), aiming to mitigate the procedural challenges experienced with current technologies. The TRISKELE valve comprises three polymeric leaflet and an adaptive sealing cuff, supported by a novel fully retrievable self-expanding nitinol wire frame. Valve prototypes were manufactured in three sizes of 23, 26, and 29 mm by automated dip-coating of a biostable polymer, and tested in a hydrodynamic bench setup in mock aortic roots of 21, 23, 25, and 27 mm annulus, and compared to two reference valves suitable for equivalent implantation ranges: Edwards SAPIEN XT and Medtronic CoreValve...

Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk. The rapid technologic advances and the recent improvement of clinical outcomes with TAVI have made it possible to treat degenerated bioprosthesis using the valve-in-valve implantation concept (Walther T, Simon P, Dewey T, et al. Transapical minimally invasive aortic valve implantation: multicenter experience...

Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect. Aortic regurgitation is the predominant hemodynamically relevant abnormality in patients with QAV, and the main reason for patients requiring valve surgery. Calcific valve disease of the left heart valves is classified as 'low embolic risk' according to current guidelines. However, it remains an important risk factor of cardiovascular events, including ischemic stroke. A 71-year-old woman presented with new-onset aphasia and hemiparesis of the right side of her body...

Infants and children born with severe cardiac valve lesions have no effective long term treatment options since currently available tissue or mechanical prosthetic valves have sizing limitations and no avenue to accommodate the growth of the pediatric patient. Tissue engineered heart valves (TEHVs) which could provide for growth, self-repair, infection resistance, and long-term replacement could be an ideal solution. Porcine small intestinal submucosa (PSIS) has recently emerged as a potentially attractive bioscaffold for TEHVs...
