Kelly Kohorst, Mias Pretorius
Mitral regurgitation is the most common valvular disease and significant (moderate/severe) mitral regurgitation is found in 2.3% of the population older than 65 years. New transcatheter minimally invasive technologies are being developed to address mitral valve disease in patients deemed too high a risk for conventional open-heart surgery. There are several features of the mitral valve (saddle-shaped noncalcified annulus with irregular leaflet geometry) that make a transcatheter approach to repair or replacing the valve more challenging compared with the aortic valve...

A 77 year old male underwent elective bioprosthetic aortic valve replacement (23mm Carpentier-Edwards Perimount MagnaEase) for severe aortic stenosis. His pre-discharge transthoracic echocardiogram (TTE) was normal. He presented 9 days after surgery with dyspnoea and fever. He was in sinus rhythm. Blood cultures were taken and he was commenced on empirical antibiotics for possible infective endocarditis (subsequently all negative). Repeat TTE showed a well-seated prosthesis without regurgitation but elevated gradients (peak / mean gradients 49 / 22 mmHg respectively)...

A combination of hypoplasia of the left side of the heart, a hypoplastic aortic arch, a large patent ductus arteriosus, and valvular pulmonary stenosis is very rare. The severity of the valvular pulmonary stenosis in this setting is difficult to judge preoperatively. Here, we describe a newborn with borderline hypoplasia of the left side of the heart, a hypoplastic aortic arch, a large patent ductus arteriosus, and valvular pulmonary stenosis, who underwent the Norwood procedure successfully. The purpose of this report is to share the perioperative course of the patient and our decision-making process that was not straightforward...

PURPOSE OF REVIEW: Left ventricular (LV) global longitudinal strain (GLS) is widely recognized as a more sensitive measure of LV systolic function compared with LV ejection fraction (LVEF). In addition, the measurement of LVGLS is more reproducible than two-dimensional LVEF. Current guidelines for diagnosis and treatment of valvular heart disease include LVEF as one of the parameters to take into consideration in the clinical decision-making. However, a large body of evidence is showing that LVGLS may be a better prognosticator than LVEF in various valvular heart diseases...

Cardiac embolism continues to be a leading etiology of ischemic strokes worldwide. Although pathologies that result in cardioembolism have not changed over the past decade, there have been significant advances in the treatment and stroke prevention methods for these conditions. Atrial fibrillation remains the prototypical cause of cardioembolic strokes. The availability of new long-term monitoring devices for atrial fibrillation detection such as insertable cardiac monitors has allowed accurate detection of this leading cause of cardioembolism...

Atrial fibrillation (AF) is a relevant cardiovascular condition that is more prevalent in the elderly patients aged over 65 years. AF, with abnormal rate and rhythm can cause symptoms directly or indirectly by exacerbating other frequently coexisting cardiac conditions such as valvular heart disease, hypertension, ischemic cardiomyopathy, dilated cardiomyopathy, and hypertrophic cardiomyopathy. Evidence suggests that aging-related cardiovascular changes predispose to the elderly to AF. Current therapeutic options such as antiarrhythmic drugs have not been extensively evaluated in the elderly population...

Induced pluripotent stem cells (iPSCs) offer an unprece-dented opportunity to study human physiology and disease at the cellular level. They also have the potential to be leveraged in the practice of precision medicine, for example, personalized drug testing. This statement comprehensively describes the provenance of iPSC lines, their use for cardiovascular disease modeling, their use for precision medicine, and strategies through which to promote their wider use for biomedical applications. Human iPSCs exhibit properties that render them uniquely qualified as model systems for studying human diseases: they are of human origin, which means they carry human genomes; they are pluripotent, which means that in principle, they can be differentiated into any of the human body's somatic cell types; and they are stem cells, which means they can be expanded from a single cell into millions or even billions of cell progeny...

Cardiovascular disease (CVD), which includes cardiomyopathy/heart failure, coronary artery disease, stroke, pericardial disease, arrhythmias, and valvular and vascular dysfunction, is a major concern for long-term survivors of childhood cancer. There is clear evidence of increased risk of CVD largely attributable to treatment exposures at a young age, most notably anthracycline chemotherapy and chest-directed radiation therapy, and compounded by traditional cardiovascular risk factors accrued during decades after treatment exposure...

Sinonasal organized hematoma, which has locally aggressive characteristics, is a non-neoplastic disease. We report a rare case of sphenoid sinus organized hematoma causing acute visual loss. A 35-year-old male presented with progressive headaches, retro-orbital pain, and frequent epistaxis. He had a medical history of aplastic anemia and of taking warfarin for a valvular heart disease. On image studies, an expansive soft tissue density lesion with bony destruction was found in his left sphenoid sinus. While waiting for elective surgery, acute visual loss occurred...

The false aneurysm of the left ventricle is a rare complication after a mitral valvular surgery. It results from the rupture of the ventricular wall inside an adhering pericardium, thus constituting a cavity whose wall is devoid of myocardial elements and communicates with the ventricle by a large collar. Its clinical presentation remains not very specific with an insidious spontaneous evolution which is generally done towards rupture with sudden death by tamponade. Various sophisticated modern diagnostic techniques allows a precise diagnosis...

Background: Rheumatic heart disease (RHD) among Ethiopian school children was recently found to be 1.4%. Immigration of the Jewish population from the Gondar region to Israel created an opportunity for further enquiry. Methods: A cross-sectional study of the cardiac status of 113,671 adolescent recruits aged 16-19 years from the northern district of Israel who completed the medical profiling process over a 22-year period. Results: 140 recruits had a history of rheumatic fever (0...

Coronary artery calcification(CAC) is reflective of atherosclerotic disease and incrementally predictive of future cardiovascular events, independent of traditional risk factors. Extra coronary calcium such as aortic valve calcification, which can be identified and quantified by Computed Tomography(CT) imaging, has shown to predict future cardiovascular events in both asymptomatic and symptomatic (ie - stable angina and acute coronary syndrome) settings. It has hence been a vital tool in studies involving new therapies for cardiovascular disease...
