BACKGROUND Over the past 10 to 15 years, calcific aortic valve disease, which includes aortic sclerosis and aortic stenosis, has come to be recognized as an active process, based on: (1) epidemiologic studies demonstrating associations of specific risk factors with increased prevalence or rate of progression of aortic valve disease; (2) identification, in valve lesions, of histopathologic featu...
A 67-year-old man with grade 3 aortic valve regurgitation was found to have a quadricuspid aortic valve. The aortic valve consisted of 1 large, 2 intermediate and 1 small sized cusp. An accessory cusp located between the right and noncoronary cusps, and shaped like a hammock which sling by the fibrous strings originating from the both commissures to the aortic wall. Aortic valve replacement was...
BACKGROUND Valve-sparing surgery including the replacement of the sinus of valsalvae were initially meant to be promising approaches in the treatment of acute type A aortic dissection. However, the long-term outcome after valve-sparing aortic root replacement in acute type A dissection is currently the subject of intense debate, and the evidence reported in the literature is sparse. Here we rep...
RATIONALE Calcific aortic stenosis (AS) is characterized by calcium deposition in valve leaflets. However, women present lower aortic valve calcification loads than men for the same AS hemodynamic severity. OBJECTIVE We, thus, aimed to assess sex differences in aortic valve fibrocalcific remodeling. METHODS AND RESULTS One hundred and twenty-five patients underwent Doppler echocardiography ...
Thirty-five consecutive patients with ventricular septal defect (VSD) associated with aortic insufficiency (AI) who underwent corrective surgery are presented. There were seven operative and three late deaths among the patients operated upon before 1968. No death, however, was encountered among the most recent 18 consecutive patients. The VSD was closed directly in 14 patients and with a Teflon...
OBJECTIVES Our goal was to determine the prevalence and characteristics of aortic valve disease in girls and women with monosomy for the X chromosome, or Turner syndrome (TS). BACKGROUND Complications from congenital aortic valve disease are a major source of premature mortality in TS, but accurate data on the prevalence of aortic valve abnormalities and their association with aortic root dil...

There were seven operative and three late deaths among the patients operated upon before 1968. No death, however, was encountered among the most recent 18 consecutive patients.

RATIONALE Percutaneous aortic valve procedures are a major breakthrough in the management of patients with aortic stenosis. Residual gradient and residual aortic regurgitation are major predictors of midterm and long-term outcome after percutaneous aortic valve procedures. We hypothesized that (1) induction/recovery of high molecular weight (HMW) multimers of von Willebrand factor defect could ...
Abstract Familial hypercholesterolemia (FH) is a hereditary dislipidemia. Patients present with extremely high level of low-density lipoprotein cholesterol (LDL-C), which is due to mutation in the gene of LDL receptor. Homozygous patients (HoFH) whose incidence is 1 in 1.000.000 are at high risk of premature aortic valve stenosis, and coronary artery atherosclerosis. In homozygous individual...
BACKGROUND Significant mitral regurgitation in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The aim of this study is to determine if surgical correction of both aortic and mitral valves in high risk patients with concomitant valvular disease would offer patients better outcomes than TAVR alone. METHODS A retrospective analysis of 43...
