Percutaneous closure of symptomatic paravalvular leaks, facilitated by integrated imaging modalities has a high rate of acute and long-term success and appears to be effective in managing symptoms of heart failure and hemolytic anemia.
Noninvasive detection of RV myocardial fibro-fatty changes in ARVD/C is possible by MDE-MRI. Magnetic resonance imaging findings had an excellent correlation with histopathology and predicted inducible VT on programmed electrical stimulation, suggesting a possible role in evaluation and diagnosis of patients with suspected ARVD/C.
We implemented a randomized field experiment that tested ways to stimulate savings by international migrants in their origin country. We find that migrants value and take advantage of opportunities to exert greater control over financial activities in their home countries. In partnership with a Salvadoran bank, we offered U.S.-based migrants bank accounts in El Salvador. We randomly varied migrant control over El Salvador-based savings by offering different types of accounts across treatment groups. Migrants offered the greatest degree of control accumulated the most savings at the partner bank, compared to others offered less or no control over savings. Impacts are likely to represent increases in total savings: there is no evidence that savings increases were simply reallocated from other savings mechanisms. Enhanced control over home-country savings does not affect remittances sent home by migrants.
CE Mark approval in September 2011 and to date over 100 commercial implants have been performed. The device is composed of a porcine biologic valve attached to a self-expanding nitinol stent designed for simple 2-step implantation and characterized by controlled positioning, self-seating in the native annulus resulting in a negligible paravalvular leak rate. The device was tested in patients at high-risk for mortality with open surgical repair. Methods: Ninety (90) patients (femaleϭ69%) with severe aortic stenosis, a mean age of 83.4 Ϯ 4.1 years, all presenting with NYHA Functional Class III or IV and a mean STS Score of 7.9 Ϯ 4.6 were enrolled in two studies in Germany at 6 centers. Patients are clinically followed at 7 and 30 days, at 6 and 12 months, and annually thereafter out to 5 years post-implant. The device was successfully implanted in 94.4% of patients (nϭ85) with a pacemaker implantation rate of 11.1% (nϭ10). Results: At 12 months the survival rate is 81.1% (nϭ73), the stroke rate is 4.4% (nϭ4), with no further re-intervention required on the implanted device since procedure. Of the returning patients, 87% presented with NYHA Functional Class I/II. The mean gradient at 6 months is 10.3 Ϯ 5.2 mmHg, the mean EOA is 1.5 Ϯ 0.4 cm2 and 77.3% of returning patients suffered no paravalvular leak, 21.2% exhibit mild paravalvular leak (ϩ1) and only 1 patient possesses a moderate paravalvular leak (ϩ2). Conclusions: These data confirm the safety profile at one year of this 2nd Generation TAVI system. We will report the full 12 months results of this multi-center, nonrandomized study of this transapically-placed transcatheter aortic valve at TCT 2012.
The avoidance and early recognition of inadvertently placed endocardial leads in the LV is imperative in order to avoid potentially serious sequelae and invasive interventions. Treatment usually consists of surgical extraction, although anticoagulation and percutaneous simple traction techniques are an option in certain scenarios.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
