Aortic Stenosis

AbstractPurpose of ReviewAortic stenosis is the most prevalent valvular heart disease. The purpose of this paper is to review the epidemiology, pathophysiology, and diagnosis of aortic valve stenosis.Recent FindingsThe diagnosis of aortic stenosis has evolved over time. Originally diagnosed with cardiac catheterization and echocardiography, more advance imaging techniques including computed tomography, magnetic resonance imaging, and 3D printing have improved our understanding of the physiology and hemodynamic effects of aortic stenosis.SummaryValvular heart disease affects a broad patient population, and the most common form of severe valve dysfunction is aortic valve stenosis. It is important to understand the prevalence of the disease and the pathophysiology of aortic stenosis. Both traditional and modern imaging modalities are used to accurately identify aortic stenosis, to define the severity, and to select patients best suited for valve replacement therapy.

Peripheral pulmonary artery stenosis (PPAS) is a relatively rare form of congenital heart disease typically associated with genetic syndromes, such as Williams or Alagille syndromes. However, some patients present with severe stenosis without associated syndromes. The purpose of the study was to review our surgical experience in such patients. This was a retrospective review of 30 patients who underwent surgical repair for peripheral pulmonary artery stenosis. Concomitant anatomical diagnoses in 20 patients (67%) included: supravalvar aortic stenosis (n=8), tetralogy of Fallot (n=4), d-transposition of the great arteries (...

AbstractHeart failure with reduced ejection fraction (HFrEF) is common in patients with adult congenital heart disease. Many of the most common congenital defects have a high prevalence of HFrEF, including left-sided obstructive lesions (aortic stenosis, coarctation of the aorta, Shone complex), tetralogy of Fallot, Ebstein anomaly, lesions in which there is a systemic right ventricle, and lesions palliated with a Fontan circulation. However, heart failure with preserved ejection fraction (HFpEF) is also prevalent in all these lesions. Comprehensive evaluation includes physical exam, biomarkers, echocardiography and advanc...

Cardiology MCQ – Least progression of valvular lesion – Answer Which of these three lesions is least likely to progressive and have a favourable clinical course among aortic stenosis, mitral regurgitation and aortic regurgitation? Correct Answer: 1. Aortic regurgitation Asymptomatic severe aortic stenosis and mitral regurgitation has poor long term outcome with overall mortality near to 10% per year, while that of asymptomatic severe aortic regurgitation is almost similar to that of age/sex matched population. 1998 AHA guidelines mentioned annual sudden death risk of only 0.2%, progression to asymptomatic left...

Brandenburg, Alexander Schuh, Rafael KramannAccelerated and premature cardiovascular calcification is a hallmark of patients with chronic kidney disease (CKD) or end-stage renal disease (ESRD). The presence and the amount of cardiovascular calcification are among the driving forces of increased morbidity and mortality in renal patients. Cardiovascular calcification occurs at different sites, including the cardiac valves—a location that is of particular importance for both the patient and the treating phy...

Authors: Mari A, Khoury T, Said Ahmad H, Abu Baker F, Kadah A, Sbeit W, Pellicano R, Mahamid M Abstract BACKGROUND: Non-alcoholic fatty liver (NAFLD) disease has become the commonest cause of end-stage liver disease. Patients with NAFLD have an increased risk of associated extrahepatic conditions, including structural and functional cardiovascular disease. Still, it is unknown if there is an association between NAFLD and valvular heart disease (VHD). OBJECTIVE: to determine the association between NAFLD and VHD. METHODS: We performed a single center retrospective study in EMMS Nazareth Hospital from April 2...

Aortic stenosis (AS) is the most common form of valvular heart disease in the elderly. As this patient population continues to increase, anesthesiologists more often will encounter these patients in the perioperative setting for noncardiac surgical procedures. Cardiac risk during noncardiac surgery in the patient with AS appears to have decreased significantly compared with previous reports that shaped current practice guidelines for perioperative management. In addition, these guidelines preceded the publication of current data supporting the continually expanding role for transcatheter aortic valve replacement in the treatment of AS.

Publication date: March 2020Source: Biomedical Signal Processing and Control, Volume 57Author(s): Ihsèn Ben Salah, Ramón De la Rosa, Kaïs Ouni, Ridha Ben SalahAbstractValvular heart diseases (VHDs) are an abnormal activity of the heart caused by a damage of one of the four heart valves. The impedance cardiography (ICG) is a non-invasive method employed to identify and classify the heart abnormalities. Despite its importance, there are not many works in scientific literature that use the ICG method in order to diagnose VHDs. Therefore, this paper deals with the ICG signal processing for the classification...

Calcific aortic stenosis (AS) is the most frequent valvular heart disease in high-income countries and the third most frequent cardiovascular disease after hypertension and coronary artery disease. The prevalence of aortic sclerosis (ie, the preclinical stage of AS) is estimated at 25% in the general population older than 65 years and close to 50% in those older than 80 years.1 The prevalence of AS is less than 1% in the population less than 60 years old,2 but increases exponentially to more than 10% in elderly people older than 75 years.
