Single-centre experience with next-generation devices for transapical aortic valve implantation ADULT CARDIAC
CONCLUSIONS In a real-world clinical setting, next-generation transapical THV yielded positive haemodynamic results. The incidence of relevant paravalvular regurgitation was scarce in this group and clinical outcomes were encouraging during short-term follow-up. Long-term follow-up is required to investigate the durability of these new devices.

Mid-term results of 17-mm St. Jude Medical Regent prosthetic valves in elder patients with small aortic annuli: comparison with 19-mm bioprosthetic valves
This study was designed to compare the mid-term outcomes after aortic valve replacement (AVR) between 17-mm mechanical heart valves (MV) and 19-mm bioprosthetic valves (BV) in elderly patients with small aortic annuli. Between 2000 and 2011, 127 consecutive patients (mean age 79 years; 87 % female) underwent AVR for aortic valve stenosis with a small aortic annulus. 19-mm BV (n = 67) was implanted. When the 19-mm BV did not fit the annulus, 17-mm St. Jude Medical Regent prosthetic mechanical valve (n = 60) was used instead of an aortic root-enlargement procedure. The follow-up rate was 94.0 % in the BV group, and 98...

Dental implants in patients at high risk for infective endocarditis: a preliminary study
Abstract: The safety of dental implant placement in patients at high risk for infective endocarditis (IE) has never been shown. The outcome of osseointegrated implants in patients with artificial heart valves or with a history of an infected valve is not known. In this article we describe our experience of dental implant placement in patients at high risk for IE. A retrospective study was conducted on patients at high risk for IE who underwent dental implant placement. All the patients received prophylactic antibiotic treatment before the surgical procedure, in accordance with the relevant American Heart Association guidel...

High survival rates in trial of new heart valve
Loyola University Medical Center is the only Chicago hospital participating in a landmark clinical trial of an artificial aortic heart valve that does not require open heart surgery. First results from the trial were announced at the Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium in San Francisco. Results were positive, with high survival rates and low rates of stroke. "This is a major breakthrough," said Fred Leya, MD, co-principal investigator at the Loyola site. "Not only did patients live longer, but their quality of life improved substantially...
