This original clinical research study id focused on description of baseline anatomy and outcomes after transcatheter aortic valve implantation (TAVI) in patients presenting with severe aortic stenosis (AS) and bicuspid aortic valve (BAV). We compared this BAV population with a population of patients with AS and tricuspid aortic valves after a propensity score matching developed by a multivariate logistic regression according to a non-parsimonious approach. Baseline anatomical characteristics were obtained by transthoracic echocardiography (TTE) and multi-sliced computed tomography (MSCT) and compared by chi-square and t-student tests...

Evaluation of antiphospholipid antibodies (aPL) and correlation with heart valve abnormalities among patients with systemic lupus erythematosus (SLE). Nested case-control study was conducted with 70 patients with SLE selected from a longitudinal database based on levels of aPL and presence or absence of valve disease by echocardiogram. Valvular abnormalities observed were regurgitation (52), other (14), artificial valves (4), stenosis (2), thickening (2) and no Libman-Sacks endocarditis (0). The mitral valve was the most commonly affected (30 abnormalities), followed by the tricuspid (20 abnormalities)...

INTRODUCTION: the incidence of invasive infections caused by pneumococcus (Streptococcus pneumoniae) has declined since generalized vaccination with pneumococcal conjugated vaccine, but it is still a prevalent pathogen in children. Amongst pneumococcal invasive infections, IE (infectious endocarditis) is rare, with an incidence between 1 and 7%. CASE REPORT: We describe the case of a previously healthy 4 year old boy, who had received one dose of 10-valent pneumococcal conjugate vaccine who presents with fever, a new heart murmur and heart failure...

High lethality of aortic dissection necessitates accurate predictive metrics for dissection risk assessment. The not infrequent incidence of dissection at aortic diameters <5.5 cm, the current threshold guideline for surgical intervention (Nishimura et al., 2014), indicates an unmet need for improved evidence-based risk stratification metrics. Meeting this need requires a fundamental understanding of the structural mechanisms responsible for dissection evolution within the vessel wall. We present a structural model of the repeating lamellar structure of the aortic media comprised of elastic lamellae and collagen fiber networks, the primary load-bearing components of the vessel wall...

A 47-year-old woman with a medical history of Raynaud's phenomenon presented with fever, cough and shortness of breath. She was found to have left lower lobe consolidation and pleural effusion and was treated as a case of pneumonia. During the hospital course, her respiratory status worsened, and she was intubated on the third hospital day. To investigate the high A-a gradient, a Computerized Tomographic Pulmonary Embolism (CTPE) study was done which identified a large left lower pulmonary artery embolism. She was also found to have a new murmur, and an echocardiogram demonstrated a large lesion on tricuspid valve...

Although vancomycin administration is recommended for the treatment of infective endocarditis (IE) caused by methicillin-resistant Staphylococcus aureus (MRSA), it is unclear whether an alternative agent, daptomycin, can be used to treat IE with pulmonary complications. A 26-year-old female who had undergone surgical repair of a ventricular septal defect as an early teenager presented with fever, headache, and vomiting. She was admitted to our hospital and diagnosed with right-sided IE with septic pulmonary embolism caused by MRSA...

OBJECTIVES: Endomyocardial biopsy sampling is used to check acute rejection after cardiac transplant. However, it may lead to tricuspid valve injury and cardiac perforation; therefore, less invasive tools may be useful. Right heart catheterization provides valuable information about cardiac hemodynamics. Herein, we aimed to determine the correlation of right heart catheterization parameters with acute rejection and death during cardiac transplant follow-up. MATERIALS AND METHODS: We retrospectively evaluated follow-up right heart catheterization and endomyocardial biopsy results from 47 adult patients who underwent cardiac transplant at Başkent University Faculty of Medicine between 2004 and 2016...

BACKGROUND Carcinoid tumor, benign, low-grade malignant, and high-grade malignant, can be associated with the release of vasoactive substances that cause symptoms including cutaneous flushing, diarrhea, and bronchospasm. In 50-60% of patients with carcinoid syndrome, the vasoactive substances cause fibrosis of the pulmonary and tricuspid heart valves which lead to regurgitation and right-sided heart failure. The right side of the heart is usually affected because monoamine oxidases in the lungs usually inactivate the vasoactive substances...

INTRODUCTION: Papillary muscle plays an important role in stabilizing the position of the tricuspid valve. Several pathologies can result in anatomical and functional abnormalities of the papillary muscles. The aim of the study is to deliberate the morphometry of papillary muscles in tricuspid valve and to analyze with the eminent research works previously done. MATERIALS AND METHODS: The study was carried out in 52 formalin-fixed adult apparently normal cadaveric hearts belonging to either sex obtained from the Department of Anatomy...

The purpose of this study was to evaluate a semi-automatic right ventricle segmentation method on short-axis cardiac cine MR images which segment all right ventricle contours in a cardiac phase using one seed contour. Twenty-eight consecutive short-axis, four-chamber, and tricuspid valve view cardiac cine MRI examinations of healthy volunteers were used. Two independent observers performed the manual and automatic segmentations of the right ventricles. Analyses were based on the ventricular volume and ejection fraction of the right heart chamber...

OBJECTIVES: The growing experience in aortic valve (AV) repair showed that annular stabilization is a crucial component to achieve stable long-term results after AV repair. Dynamic changes in the AV annulus during the cardiac cycle may have an impact on annuloplasty design. METHODS: We retrospectively analysed full cardiac cycle multislice computed tomography data from 58 consecutive patients (mean age 75.9 ± 6.5 years, 36% men) with normally functioning tricuspid AVs (normal AV subgroup)...

Surgical treatment of severe functional tricuspid regurgitation associated with dilated right ventricle and increased chordal tethering (>8 mm) is challenging. We designed a technique where the anterior and posterior leaflets are detached from 50% of the annulus and a patch as large as the tricuspid orifice is sewn to augment the leaflets' tissue to force the coaptation with the septal leaflet. Annuloplasty is not performed, as it can only increase the chordal tethering, reducing the benefit of tissue augmentation...

Carcinoid tumors are rare, mainly located in the gastrointestinal tract particularly in the small intestine. Cardiac involvement, fairly frequent and usually affecting right sided heart valves, had a poor prognosis that is improved by an earlier detection and valve surgery. We report the case of a 50-years old woman with neuroendocrine tumor and liver metastases, in whom carcinoid involvement of the right heart was diagnosed following exertional dyspnea. She had dilated right cavities, severe tricuspid regurgitation, mild tricuspid stenosis and a moderate pulmonary stenosis...

We present the case of a 72-year-old woman diagnosed with rheumatic fever at the age of 6. In 1972, she was diagnosed with mitral valve insufficiency and mitral valve stenosis, then in 1974, a decision was made to perform mitral valve replacement surgery with a 32-mm Braunwald-Cutter ball cage prosthesis. An echocardiogram performed in 2014 revealed normal biventricular systolic function, mechanical prosthesis in mitral position with maximum speed of 1.9 m/s, maximum gradient of 15 mmHg, mean gradient of 6 mmHg, severe tricuspid valve insufficiency, inferior vena cava measuring 15 mm with more than 50% collapse and pulmonary artery systolic pressure of 40 mmHg...
