Hemodynamic assessment of paravalvular aortic regurgitation after TAVI: estimated myocardial supply-demand ratio and cardiovascular mortality.
A relevant (at least moderate) paravalvular regurgitation (PAR) after transcatheter aortic valve implantation (TAVI) is found in up to 20% of cases and associated with increased mortality. The ratio of the diastolic over the systolic pressure time integral (DPTI:SPTI) has been proposed to reflect an estimate of myocardial oxygen supply versus demand and the propensity for myocardial ischemia. W...

هدف اصلی از این مطالعه بررسی نوع و میزان استراتژی هایی بود که دانشجویان فارسی زبان رشته ی زبان انگلیسی در حین خواندن یک متن انگلیسی به کار گرفتند. این مطالعه همچنین به بررسی تفاوت های استراتژی های مورد استفاده بین دارندگان سطح بالا و پایین درک مطلب پرداخت. نوع همبستگی بین استراتژی به کار گرفته و درک مطلب از یک سو و استراتژی به کار گرفته و انگیزه از سوی دیگر نیز در این تحقیق مورد آزمایش قرار گرف...
15 صفحه اولValue of CMR in quantification of paravalvular aortic regurgitation after TAVI.
AIMS To assess the value of cardiac magnetic resonance (CMR) using phase-contrast velocity mapping for paravalvular aortic regurgitation (PAR) quantification. METHODS AND RESULTS All patients undergoing transcatheter aortic valve implantation (TAVI) in our centre between November 2012 and August 2013, without CMR-contraindication were included. PAR severity was assessed 5 days after TAVI usin...
متن کاملTranscatheter aortic valve implantation (TAVI) in patients with aortic regurgitation.
Transcatheter aortic valve implantation (TAVI) has become the standard of care for elderly high-risk patients presenting severe and symptomatic aortic valve stenosis, while surgical aortic valve replacement (sAVR) is still considered as the treatment of choice for younger patients and patients with low and intermediate risk profiles (1,2). With more than 100,000 implants worldwide, TAVI has cha...
