BACKGROUND: Few centers for open heart surgery (OHS) are in Sub-Saharan Africa. Lack of OHS results is also noted. By reporting our African experience on OHS, the aim of this study was to fill the gap. METHODS: It is a retrospective study on 2,612 patients who were subject to an OHS between 1978 and 2013. Data were collected from demographical, clinical, investigative studies, surgical and outcomes parameters. RESULTS: There were 1,475 cases of rheumatic heart diseases (RHD), 126 endomyocardial fibrosis (EMF), 741 congenital heart diseases (CHDs) and 270 various affections...

Leptotrichia species are normal constituents of the oral cavity and the genitourinary tract microbiota that are known to provoke disease in immunocompromised patients and rarely in immunocompetent individuals. Following the description of Leptotrichia goodfellowii sp. nov., two cases of endocarditis by this species have been reported. Here, we report a case of Leptotrichia goodfellowii endocarditis in an immunocompetent patient with a valvular allograft. The isolation and identification of Leptotrichia can be challenging, and it is likely that infection with this pathogen is significantly underdiagnosed...

BACKGROUND: Bicuspid aortic valve is the most common cardiovascular congenital malformation affecting 2% of the general population. The incidence of life-threatening complications, the high heritability, and familial clustering rates support the interest in identifying risk or protective genetic factors. The main objective of the present study was to identify population-based genetic variation associated with bicuspid aortic valve and concomitant ascending aortic dilation. MATERIALS AND METHODS: A cross-sectional exome-wide association study was conducted in 565 Spanish cases and 484 controls...

BACKGROUND: Higher red cell distribution width (RDW) predicts adverse events in patients with cardiovascular diseases. However, there are limited data regarding the relationship between RDW and thromboembolism risk in the patients with atrial fibrillation (AF). We aimed to investigate the association between RDW and CHADS2, CHA2DS2-VASc scores used for the evaluation of thromboembolic risk in patients with non-valvular atrial fibrillation (AF). METHODS: Our study included 99 patients with AF (68 paroxysmal AF; 31 persistent AF)...

Although preliminary data suggests that ibrutinib may increase risk of atrial fibrillation (AF), the incidence of AF in a general cohort of chronic lymphocytic leukemia (CLL) patients is unknown. We evaluated the prevalence of AF at CLL diagnosis and incidence of AF during follow-up in 2444 patients with newly diagnosed CLL. A prior history of AF was present at CLL diagnosis in 148 (6.1%). Among the 2292 patients without history of AF, 139 (6.1%) developed incident AF during follow-up (incidence approximately 1%/year)...

CONTEXT AND AIMS: The advent of systematic screening for rheumatic heart disease (RHD) by echocardiography in endemic regions has led to a new entity: borderline RHD. The pathogenicity and natural history of borderline RHD needs to be addressed. The aim of this study was to assess the outcomes of children detected by echocardiography as having borderline RHD. METHODS: Schoolchildren in 4th grade (i.e., aged 9-10years) who were prospectively echo-screened for RHD (2012-2014) in Nouméa, New Caledonia, were asked to participate...

BACKGROUND: There are limited data regarding the influence of liver dysfunction on outcomes of transcatheter aortic valve implantation (TAVI). Model for End-stage Liver Disease eXcluding International normalized ratio (MELD-XI) score, which was originally developed for patients with cirrhosis awaiting liver transplantation, has been reported as a predictor of heart disease. The aim of this study was to investigate the prognostic value of MELD-XI score for patients undergoing TAVI. METHODS: Data from the prospectively maintained Optimized transCathEter vAlvular iNtervention (OCEAN-TAVI) multicenter registry were collected in 749 patients who underwent TAVI between October 2013 and August 2015...

BACKGROUND: -Although HF disproportionately affects older adults, little data exist regarding the prevalence of American College of Cardiology/American Heart Association heart failure (HF) stages among older individuals in the community. Additionally, the role of contemporary measures of longitudinal strain (LS) and diastolic dysfunction in defining HF stages is unclear. METHODS: -HF stages were classified in 6,118 participants in the Atherosclerosis Risk in Communities study (age 67 - 91 years) at the fifth study visit as follows: stage A (asymptomatic with HF risk factors but no cardiac structural or functional abnormalities), B (asymptomatic with structural abnormalities, defined as left ventricular hypertrophy, dilation or dysfunction, or significant valvular disease), C1 (clinical HF without prior hospitalization), and C2 (clinical HF with prior hospitalization)...

RATIONALE: Calcific aortic stenosis (AS) is characterized by calcium deposition in valve leaflets. However, women present lower aortic valve calcification (AVC) loads than men for the same AS hemodynamic severity. OBJECTIVE: We thus aimed to assess sex-differences in aortic valve fibro-calcific remodelling. METHODS AND RESULTS: One hundred and twenty-five patients underwent Doppler-echocardiography and multidetector-computed-tomography within 3 months prior to aortic valve replacement...

AIMS: Impaired left ventricular (LV) deformation despite preserved LV ejection fraction (LVEF) is common and predicts outcomes in heart failure with preserved LVEF. We hypothesized that impaired LV deformation at rest is a marker of impaired cardiac systolic and diastolic reserve, and aimed to determine whether resting longitudinal (LS) and circumferential strain (CS) are associated with invasively measured haemodynamic response to exercise in patients with dyspnoea and a normal LVEF...

Intense enhancement of the mitral valve is documented in a MRI examination performed on a patient with rheumatic multi-valvular disease. Patient had the elevated inflammatory markers indicating active inflammatory process. Such hitherto undocumented phenomenon may have important clinical significance in disease evaluation, thus provide a feasible option to document and follow up, active valvular involvement in patients with active rheumatic fever.

Few studies discuss the risk factors for acute cardiac lesions (within 30 days) resulting from Kawasaki disease (KD). We aimed to clarify the characteristics of patients with cardiac lesions within 30 days and determine the risk factors for acute cardiac lesion subtypes. Using the 23rd nationwide survey of KD in Japan, we analyzed data from patients with or without acute cardiac lesions resulting from KD (n = 31,380). We subdivided patients with acute cardiac lesions into three types: acute valvular lesions, coronary aneurysms, and giant coronary aneurysms (GCA), and calculated the odds ratios of potential risk factors for acute cardiac lesion subtypes...

Aortic valve stenosis (AS) is a major cause of morbidity and mortality, with no effective medical therapies. Investigation into the underlying biology of AS in humans is limited by difficulties in obtaining healthy valvular tissue for use as a control group. However, micro-ribonucleic acids (miRNAs) are stable in post-mortem tissue. We compared valve specimens from patients undergoing aortic valve replacement for AS to non-diseased cadaveric valves. We found 106 differentially expressed miRNAs (p < 0...

BACKGROUND: Globally, heart failure (HF) has been recognized as one of the major cardiovascular disorder with high morbidity, mortality and considerable social impact. In Sub Saharan African countries, HF has turned out as a leading form of cardiovascular diseases, and has considerable socioeconomic impact. However, there are differences in clinical characteristics and survival status among patients with preserved (HFpEF) and reduced (HFrEF) ejection fraction. The aim of this study is to outline the clinical characteristics and medication profile, assess the survival status and prognostic factors of Ethiopian HF patients with HFrEF and HFpEF...

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...

The use of ultrasound waves in conjunction with local thrombolysis may accelerate clot resolution and serve as an important therapeutic adjunct in the treatment of venous occlusive disease. Our goal was to provide a larger sample population over a 5-year period to evaluate our experience with the EkoSonic endovascular system (EKOS, EKOS Corporation, Bothell, WA). We suspected that ultrasound-accelerated thrombolysis (UAT) using EKOS would provide excellent thrombolysis and midterm patency rates with minimal thrombolytic complications...
