BACKGROUND: The aim was to assess whether cardiovascular adaptation to pregnancy in women with repaired tetralogy of Fallot (TOF) adversely affects hemodynamic stability, in particular with respect to right ventricular (RV) dilatation, pulmonary regurgitation, or aortic root dilatation. METHODS AND RESULTS: This was a retrospective cohort study of women with repaired TOF with paired cardiovascular magnetic resonance scans before and after their first pregnancy (baseline RV end systolic volume index 49 mL/m(2) and RV end diastolic volume index 118 mL/m(2)) matched with a comparison group of nulliparous women with TOF...

OBJECTIVES: This study sought to determine if indexed effective orifice area (EOAi), using left ventricular outflow tract measured from computed tomography (EOAiCT), reclassified prosthesis-patient mismatch (PPM) compared with conventional echocardiogram-defined measurements (EOAiTTE). BACKGROUND: PPM does not predict mortality following transcatheter aortic valve replacement (TAVR). However, it is unknown if the EOAiCT of the left ventricular outflow tract improves risk stratification...

The goal of this study was to generate reference intervals for echocardiographic variables in a population of clinically normal geriatric rhesus macaques (Macaca mulatta). To do this, we studied 51 animals (age, 18-29 y; weight, 5.24-17.04 kg). The normal values for cardiac indices, including geometry and systolic and diastolic function, were determined by 2D, M-mode, spectral Doppler, and tissue Doppler echocardiography under ketamine hydrochloride sedation. Statistical correlations between the echocardiographic parameters and age, body weight, sex, and heart rate were investigated...

The article deals with the problems of acquired valvular disorders. It mainly focuses on the new findings regarding ethiopathogenesis, diagnostics, evaluation and treatment, especially catheterization. In advanced countries, post-rheumatic abnormalities have almost disappeared, their current etiology has substantially changed (mitral stenosis). The earlier relatively rare degenerative changes now predominate, mainly affecting older patients (aortic stenosis). Also the treatment methods for acquired abnormalities have substantially changed - currently catheterization approaches are used more frequently in their correction...

BACKGROUND: Stress echocardiography (SE) is widely used in Europe. No collective data have been available on the use of SE in Poland until now. AIM: To evaluate the number of SE investigations performed in Poland, their settings, complications and results. METHODS: In this retrospective survey, referral cardiology centers in Poland were asked to fill in a questionnaire regarding SE examinations performed from May 01, 2014 to May 01, 2015. RESULTS: The study included data from 17 university hospitals and large community hospitals which performed 4611 SE examinations, including 4408 tests in patients investigated for coronary artery disease (CAD) and 203 tests to evaluate valvular heart disease (VHD)...

Technical selection for surgical repair of complete atrioventricular septal defect (CAVSD) still remains controversial. This meta-analysis aimed to compare the modified single-patch (MP) technique with the two-patch (TP) technique for patients with CAVSD. Relevant studies comparing the MP technique with the TP technique were identified through a literature search using MEDLINE, EMBASE, Google Scholar, Cochrane Library, and the China National Knowledge Infrastructure databases. The variables were ventricular septal defect (VSD) size, cardiopulmonary bypass (CBP) time, aortic cross-clamp (ACC) time, intensive care unit stay, hospital stay, and other outcomes involving mortality, left ventricular outflow tract obstruction, atrioventricular valve regurgitation, residual septal shunt, atrioventricular block, and reoperation...

BACKGROUND: The traditional treatment of subarterial ventricular septal defect (VSD) is open heart surgery. This study aimed to evaluate the feasibility, safety and outcome of transcatheter closure with the Amplatzer duct occluder (ADO). METHODS: Between March 2012 and June 2015, a total of 16 patients (8 male and 8 female) with subarterial VSD who underwent transcatheter closure with the ADO were enrolled retrospectively. Their age ranged from 3.0 to 65.6 years, with the median of 35...

Infective endocarditis (IE) during pregnancy is a rare but serious condition. Cardiopulmonary bypass during pregnancy has a high rate of fetal morbidity and mortality. We here report the case of a 22-year-old pregnant woman with confirmed IE. Multiple large cardiac valve vegetations, severe aortic valve regurgitation, and hemodynamic compromise were observed. With full implementation of fetal monitoring and protection strategies, open heart surgery was performed at 31.4 weeks' gestation to aid survival, followed by an elective cesarean delivery at 34...

The tricuspid valve (TV), although occasionally considered "neglected" is the subject of renewed and increasing interest. Factors include an awareness that tricuspid value dysfunction is influential in patient outcomes, an improving understanding of valve anatomy and function and evolving techniques available to address tricuspid regurgitation. Tricuspid regurgitation (TR) can be classified as being due to primary diseases of the valve or functional in nature, with the majority being functional. Whilst it was previously believed that such functional TR, resulting from left sided disease, would resolve after correction of the underlying pathology this is now known not to be true...

REVIEW
Andrei D Mǎrgulescu
Aortic valve disease [aortic stenosis (AS) and aortic regurgitation (AR)] represents an important global health problem; when severe, aortic valve disease carries poor prognosis. For AS, aortic valve replacement, either surgical or interventional, may provide definite treatment in carefully selected patients. For AR, valve surgery (either replacement or - in selected cases - aortic valve repair) remains the gold standard of care. To properly identify those patients who are candidates for surgery, the clinician has to carefully assess the severity of valve disease with an understanding of the potential pitfalls involved in these assessments...

OBJECTIVE: To report a first case series of the Lotus valve (Boston Scientific) for the treatment of surgical aortic bioprosthesis failure. BACKGROUND: Valve-in-valve (VIV) transcatheter aortic valve implantation (TAVI) is an established management option for surgical aortic bioprosthesis failure. Although TAVI has proven efficacious, complications relating to suboptimal valve implantation have been reported in approximately 5% of patients. The Lotus valve is fully repositionable and retrievable, and therefore enables complete assessment of valve function prior to definitive deployment...

OBJECTIVE: Dravet syndrome (DS) is a rare, treatment-resistant epilepsy syndrome for which current treatment regimens are often ineffective. Fenfluramine is currently in development for treatment of DS based on reports in the 1980s and 1990s of its antiepileptic activity in pediatric patients with intractable epilepsy. However, fenfluramine was withdrawn from global markets in 1997 following reports of its association with pulmonary hypertension and heart valve disease in adult patients treated for obesity...

Background: Mitral valve regurgitation (MR), present in up to 74% of the patients with severe aortic stenosis (AS), can be a negative prognostic factor when moderate or severe. The outcome of MR after percutaneous transcatheter aortic valve implantation (TAVI) and predictors associated with that outcome have not been well established in the literature. Objective: To assess the outcome of primary MR in patients submitted to TAVI and to identify associated factors...

A 77-year-old man presented with exertional dyspnea. The patient had a history of ankylosing skeletal hyperostosis and sleep apnea syndrome. Echocardiographic examination revealed severe aortic valve regurgitation. The patient underwent a prophylactic tracheostomy 2 weeks before cardiac surgery to decrease his risk of perioperative respiratory failure. He successfully underwent aortic valve replacement through a lower partial sternotomy. His postoperative course was uneventful, and the tracheostoma was closed 6 months after the cardiac surgery...

BACKGROUND: Reversibility of left ventricular (LV) dysfunction in high-risk aortic stenosis patient and its impact on survival after transcatheter aortic valve replacement (TAVR) are unclear. We aimed to evaluate longitudinal changes of LV structure and function after TAVR and their impact on survival. METHODS AND RESULTS: We studied 209 patients with aortic stenosis who underwent TAVR from May 2006 to December 2012. Echocardiograms were used to calculate LV end-diastolic volume index (LVEDVi), LV ejection fraction, LV mass index (LVMi), and global longitudinal strain before, immediately (<10 days), late (1-3 months), and yearly after TAVR...
