Background Indian patients undergoing surgical aortic valve replacement (SAVR) differ from western populations with respect to aortic annulus size and valve disease morphology. n In all valve sizes, the Trifecta valve had the lowest mean pressure gradient. Detailed hemodynamic data on the Trifecta aortic valve bioprosthesis have been released by 8 – 10 Transcatheter aortic valve implantation (TAVI) is a less-invasive alternative to open heart surgery in selected patients with aortic valve disease. J Heart Valve Dis Vol. A potential problem in AVR remains prosthesis-patient mismatch (PPM) as defined by Rahimtoola [1]. Our data indicate that the Trifecta valve might have a slightly better performance than the matched CEP valve. The Trifecta TM valve with Glide Technology (GT) and Linx anticalcification (AC) technology offers exceptional hemodynamics 1-6,* and excellent performance 7 —whether implanted via a minimally invasive procedure or conventional surgical aortic valve replacement (SAVR). The postoperative period was uneventful. Low aortic valve gradient is a result of aortic stenosis, a narrowing of the opening of the aortic valve. Therefore, the appropriate prosthesis size must be selected to maximize the effective orifice area (EOA) in order to prevent PPM. Subclinical leaflet thrombosis was … Of note, 99.5% of patients had mild or no aortic insufficiency at discharge. The Trifecta valve offers a good alternative to other biological stented aortic valves. We were unable to perform 3D-TOE planimetry in 2 patients due to extensive valve calcification that prevented us from correctly identifying the valve opening area. The stent, excluding the true supra-annular sewing cuff, is covered with porcine pericardial tissue and the valve leaflets are manufactured using bovine pericardial tissue, which is wrapped around the intrinsically distensible titanium stent, rather than mounted inside. The advent of transcatheter aortic valve therapies has … Product Details 518 Performance of the SJM Trifecta bioprosthetic valve A. Yadlapati et al.

Methods. Number at risk for Valve Dysfunction at last follow-up not reported) The incidence of calcified aortic valve disease has been increasing in elderly patients and aortic valve replacement (AVR) with a bioprosthesis is the standard therapy for these patients. Measurements of mean systolic pressure gradients, EOAI and valvular resistance (VR) for both the Trifecta and Freestyle valves remained relatively constant when measured at rest, peak exercise and recovery. This is even less frequent when it is not associated with endocarditis, thrombus formation, or structural valve deterioration. transcatheter aortic valve replacement. Early and mid-term outcome in terms of functional and hemodynamic … Operative mortality for redo valve surgery may be higher than 20% in such high-risk patients, whereas in low-risk patients, it may be Ͻ4% (8,12).Transcatheter aortic valve replacement for native aortic stenosis has evolved as a viable alternative to open heart surgery in patients with high or prohibitive surgical risk … Between 2010 and 2021, Hima Patel wrote the following 17 eligible articles about Aortic Valve Stenosis: + Citations-Citations + Abstracts-Abstracts. Normal aortic velocity would be greater than 3.0m/sec (3.0 meters per second), while a normal mean pressure gradient would be from zero to 20mm Hg (20 millimeters of mercury, which is how blood pressure is measured). Trifecta vs. Magna for Aortic Valve Replacement ... Transthoracic echocardiographic assessment of the mean pressure gradient (MPG) for each valve: unadjusted A (actual) data and (B) interaction between time points (at discharge, 1 year postoperatively, at follow-up) and valve type (Trifecta Aortic stenosis is the most common valvular heart disease in Europe and North America [1, 2].Among randomly selected men and women aged 75 to 86 years, the prevalence of critical aortic valve stenosis is 2.9% [].Due to the aging population, approximately 150,000 patients of a total population of 64 million in England are projected to have severe aortic stenosis by 2020 []. 23. 162 , 238–245.e1 (2011). While aortic valve treatment has been traditionally reserved for open surgery, the development of TAVR has challenged this [9,10,11]. Mean effective orifice area (EOA) ranged from 1.61 cm(2) (size 19 valve) to 2.5 cm(2) (size 27 valve). A total of 791 patients underwent aortic valve replacement (469 Magna Ease, 322 Trifecta). Surgeons tend to strive to implant a prosthesis as big as possible, with the goal of delivering a low-gradient, high EOA valve, that would mimic, as close as possible, a healthy, normal, functioning aortic valve.
