Congenital heart block (CHB) is rare disorder that has a higher mortality when associated with structural congenital heart defects. Very few cases have been reported in Sub-Saharan Africa (SSA). We present a case of complete CHB associated with a complex congenital heart defect in a neonate in Cameroon. A 1-month-old neonate in Cameroon was referred for the evaluation of bradycardia. The obstetrical ultrasound done during pregnancy revealed fetal bradycardia without further evaluation. Clinical examination showed well a developed neonate with bradycardia at 62 beats/minute, and mild cyanosis with oxygen saturation at 93% at room air...

BACKGROUND: The aim of the present study was to evaluate the echocardiographic follow-up of patent foramen ovale, which is considered a potential etiological factor in various diseases, and to determine the factors affecting spontaneous closure. METHODS: Between January 2000 and June 2012, records of 918 patients with patent foramen ovale were retrospectively reviewed. Patency of less than 3 mm around the fossa ovalis is called patent foramen ovale. Patients with cyanotic congenital heart diseases, severe heart valve disorders and severe hemodynamic left to right shunts were excluded from the study...

Lymphatic valves (LVs) are cusped luminal structures that permit the movement of lymph in only one direction and are therefore critical for proper lymphatic vessel function. Congenital valve aplasia or agenesis can, in some cases, be a direct cause of lymphatic disease. Knowledge about the molecular mechanisms operating during the development and maintenance of LVs may thus aid in the establishment of novel therapeutic approaches to treat lymphatic disorders. In this study, we examined the role of Connexin43 (Cx43), a gap junction protein expressed in lymphatic endothelial cells (LECs), during valve development...

PURPOSE: Generally, aspirin is used as a protective agent against thrombogenic phenomenon after pulmonary valve replacement (PVR) using a bioprosthetic valve. However, the appropriate duration of aspirin use is unclear. We analyzed the impact of postoperative duration of aspirin use on the longevity of bioprosthetic pulmonary valves in patients who underwent repair for congenital heart diseases. METHODS: We retrospectively reviewed the clinical data of 137 patients who underwent PVR using a bioprosthetic valve between January 2000 and December 2003...

Cardiovascular diseases continue to be a major cause of mortality and morbidity in the world population. First open heart procedure was performed by Gibbon in 1953, since then many advancements have been introduced to the field of cardiac surgery. Minimally invasive techniques were introduced, which include minimally invasive coronary artery bypass grafting (CABG), off-pump technique, minimally invasive valve surgery or transcatheter techniques to implant stentless or sutureless valves. The hybrid strategy to address coronary disease combines catheterisation procedures with standard surgical techniques...

BACKGROUND: Cardiac rehabilitation (CR) is an evidence-based intervention to increase survival and quality of life. Yet studies consistently show that elderly patients are less frequently referred to CR, show less uptake and more often drop out of CR programmes. DESIGN: The European study on effectiveness and sustainability of current cardiac rehabilitation programmes in the elderly (EU-CaRE) project consists of an observational study and an open prospective, investigator-initiated multicentre randomised controlled trial (RCT) involving mobile telemonitoring guided CR (mCR)...

The prevalence of aortic valve stenosis (AS) is increasing in the aging society. More recently, novel treatments and devices for AS, especially transcatheter aortic valve replacement (TAVR) have significantly changed the therapeutic approach to this disease. Research and development related to TAVR require testing these devices in the calcified heart valves that closely mimic a native calcific valve. However, no animal model of AS has yet been available. Alternatively, animals with normal aortic valve that are currently used for TAVR experiments do not closely replicate the aortic valve pathology required for proper testing of these devices...

Differentiation of constrictive pericarditis (CP) from restrictive cardiomyopathy (RCM) is a complex and often challenging process. Because CP is a potentially curable cause of heart failure and therapeutic options for RCM are limited, distinction of these 2 conditions is critical. Although different in regard to etiology, prognosis, and treatment, CP and RCM share a common clinical presentation of predominantly right-sided heart failure, in the absence of significant left ventricular systolic dysfunction or valve disease, due to impaired ventricular diastolic filling...

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...

Aortocoronary bypass or valve surgery usually require cardiac arrest using cardioplegic solutions. Although, in principle, in a number of cases beating heart surgery (so-called off-pump technique) is possible, aortic or valve surgery or correction of congenital heart diseases mostly require cardiopulmonary arrest. During this condition, the heart-lung machine also named cardiopulmonary bypass (CPB) has to take over the circulation. It is noteworthy that the invention of a machine bypassing the heart and lungs enabled complex cardiac operations, but possible negative effects of the CPB on other organs, especially the brain, cannot be neglected...

BACKGROUND: A small mitral valve aneurysm (MVA) presenting as severe mitral regurgitation (MR) is uncommon. CASE PRESENTATION: A 47-year-old man with a history of hypertension complained of exertional chest discomfort. A transthoracic echocardiogram (TTE) revealed the presence of MR and prolapse of the posterior leaflet. A 6-mm in diameter MVA, not clearly visualized by TTE, was detected on the posterior leaflet on a three-dimensional (3D) transesophageal echocardiography (TEE)...

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...

In the past few decades, analysis of heart sound signals (i.e. the phonocardiogram or PCG), especially for automated heart sound segmentation and classification, has been widely studied and has been reported to have the potential value to detect pathology accurately in clinical applications. However, comparative analyses of algorithms in the literature have been hindered by the lack of high-quality, rigorously validated, and standardized open databases of heart sound recordings. This paper describes a public heart sound database, assembled for an international competition, the PhysioNet/Computing in Cardiology (CinC) Challenge 2016...

With the population aging and declining incidence of rheumatic heart disease, calcific aortic valve disease (CAVD) has become the most frequent valve disease and the common cause of aortic valve replacement. Patients with CAVD need to cope with a deteriorating quality of life and valve replacement is the only effective clinical option for the patients. Therefore, early pharmacotherapy is of great significance in prevention or slow-down of the progression of CAVD. For years CAVD was considered to be a passive wear and tear process of valves, but now it is recognized as an active and multi-factorial process...

Aortic stenosis is the most frequent and mitral stenosis is the least frequent native single-sided valve disease in Europe. Patients with the combination of severe symptomatic degenerative aortic and mitral stenosis are very rare. Guidelines for the treatment of heart valve diseases are clear for single-valve situations. However, there is no common agreement or recommendation for the best treatment strategy in patients with multiple valve disease and severe concomitant comorbidities. A 76-year-old female patient with the combination of severe degenerative symptomatic aortic and mitral stenosis and several comorbidities including severe obesity, who was found unsuitable surgical candidate by the heart team and unsuitable for two-time general anesthesia in the case of two-step single-valve percutaneous approach by anesthesiologists, underwent successful percutaneous dual-valve single-intervention (transcatheter aortic valve implantation and percutaneous mitral balloon commissurotomy)...
