How Does Elevated Lipoprotein(a) Cause Aortic Valve Stenosis?
L ipoprotein(a) [Lp(a)] was discovered in 1963 by Kaare Berg in Norway, and elevated levels were already then considered a cardiovascular risk factor (1). For many years, Lp(a) received only moderate scientific and clinical attention; however, in recent years, important new evidence has emerged, and elevated Lp(a) is now considered a causal risk factor for cardiovascular disease. Genetic varian...
متن کاملSUPRAVALVAR AORTIC STENOSIS IN CHILDREN REPORT OF THIRTEEN CASES
During 15 years from 1975 to 1990, thirteen cases of supravalvar aortic stenosis were admitted at the pediatrics department of Shahid Rajai Heart Hospital, Tehran. All patients were subjected to cardiac catheterization and a angiocardiography. Patients ranged in age from 3.5 years to 14 years with a mean of 8.7 years. Seventy seven percent of childen were male. Eight cases (61.5%) had Wil...
متن کاملVentricular function in aortic stenosis: how low can you go?
In 1980, we reported that patients with aortic stenosis (AS) who had a low mean gradient ( 30 mm Hg) and low ejection fraction ( 0.30) fared poorly following aortic valve replacement (AVR) (1). We also demonstrated that while ejection fraction may be reduced in AS either because of afterload mismatch or contractile dysfunction, in patients with low transvalvular gradient, afterload mismatch is ...
متن کامل[Dyspnea in aortic stenosis: appearances can be deceptive].
Valvular aortic stenosis is the most common valvular disorder in Europe. Although recommended, stress exams are still underused in its evaluation. We report the case of a 60-year-old man who, following a routine electrocardiogram with abnormal ventricular repolarization, underwent stress testing, which was positive for myocardial ischemia, and an echocardiogram that revealed moderate aortic ste...
متن کاملAssociation of body mass index and visceral fat with aortic valve calcification and mortality after transcatheter aortic valve replacement: the obesity paradox in severe aortic stenosis
BACKGROUND Previous studies showed that metabolic syndrome is associated with aortic valve calcification (AVC) and poor outcomes in aortic stenosis (AS). However, if these associations change and how body fat impacts the prognosis of patients in late stage of the disease have been not yet explored. AIMS To determine the association of body mass index (BMI) and visceral fat with AVC and mortal...
