Context: Lipoprotein(a) is a genetic risk factor for myocardial infarction and aortic valve stenosis. APOE ε2/3/4 genotypes affect plasma lipoprotein(a); however, the effects of APOE genotypes on the prediction of myocardial infarction and aortic valve stenosis by lipoprotein(a) are unknown. Objective: We tested the hypothesis that APOE ε2/3/4 genotype affects plasma lipoprotein(a), the contribution of plasma apoE levels this effect, and the associated risk of myocardial infarction and aortic valve stenosis...

Calcific aortic stenosis (AS) plays a critical role in the risk of cardiovascular disease. This preliminary study examined the relationship between the ex vivo valve thickness/calcification and in vivo clinical outcomes of Chinese patients with calcific AS. Six Chinese patients (3 patients with tricuspid aortic valves (TAV)) and 3 patients with. bicuspid aortic valves (BAV) with calcific AS undergoing heart valve replacement were initially chosen for this study. In vivo medical imaging of these calcific AS patients was evaluated using computed tomography and echocardiography...

BACKGROUND: Contemporary transcatheter aortic valve implantation (TAVI) devices and approach present opportunities to review historical practices initially informed by early treatment development and cardiac surgery. The avoidance of urinary catheterization in the older TAVI population is a strategy to minimize in-hospital complications. The purpose of the study was to explore elimination-related complications following the phased implementation of a default strategy of avoiding urinary catheterization in patients undergoing transfemoral (TF) TAVI...

Paravalvular leaks are common following valve replacement surgery. Majority are benign and do not require any active intervention. However, occasionally severe paravalvular regurgitation can produce heart failure and/or hemolysis, needing closure of the defect. It is more commonly associated with aortic and mitral prosthesis, symptomatic tricuspid paravalvular regurgitation being a rare entity. In this report we present the successful percutaneous transcatheter closure of a large paravalvular tricuspid regurgitation in a 59-year old lady with history of multiple previous operations...

In the present study, we assessed the role of Global Longitudinal Strain (GLS) as a predictor of all-cause mortality in patients with severe aortic valve stenosis (AS), irrespective of their type of treatment. Data of 807 patients with AS receiving complete echocardiographic and clinical examination were retrospectively analyzed. Valve area <1 cm(2) and sufficient image quality were inclusion criteria; patients with severe concomitant valvulopathy were excluded. Patients were grouped into treatment (aortic valve replacement [AVR]) and conservative (non-AVR) groups...

Late transcatheter heart valve embolization is a rare but life-threatening complication of transcatheter aortic valve implantation. Surgical intervention is performed for most cases, but some cases were treated by valve-in-valve transcatheter aortic valve implantation. We describe a patient in whom a 29-mm Edwards SAPIEN XT valve migrated into the left ventricular outflow tract 41 days after the initial implantation. We tried to perform valve-in-valve transcatheter aortic valve implantation using a transfemoral approach...

A variety of syndromic diseases such as Marfan syndrome, Loeys-Dietz syndrome, and bicuspid aortic valve with aneurysm along with risk factors of smoking and hypertension result in ascending aortic aneurysms and dissections. Historically, a complicated variety of terms have been used to describe a range of histopathologies that are present in resected specimens. As a result, no consistent patterns of histopathology have been reported. We used the recent Society for Cardiovascular Pathology/Association for European Cardiovascular Pathology consensus statement on nomenclature and diagnostic criteria for noninflammatory aortic disease to blindly evaluate 148 surgically resected specimens...

OBJECTIVE: Although aortic valve-sparing operations are performed throughout Japan, the indications, specific repair techniques, and outcomes have not been reported in full. Thus, we conducted the first nationwide survey of aortic valve-sparing surgery. METHODS: We mailed a questionnaire to 508 institutions across Japan to obtain information on elective aortic valve and aortic root surgeries performed in 2014. Included in the mailing was a secondary questionnaire that sought further information from institutions reporting aortic valve-sparing surgeries...

Patients undergoing TAVR undergo routine CT angiography (CTA) to assess aorto-iliac pathology and annular dimensions. While coronary CTA may exclude severe CAD in younger patients, its efficacy in defining CAD severity prior to TAVR may be limited. We retrospectively studied 50 consecutive patients undergoing both invasive coronary angiography (ICA) and routine pre-TAVR CTA. Severe CAD was defined as ≥50% stenosis by quantitative coronary angiography and compared to a blinded CTA visual estimation of ≥50% stenosis...
