OBJECTIVES We compared the annulus diameters measured by transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and dual-source computed tomography (DSCT) before transcatheter aortic valve implantation (TAVI). BACKGROUND In TAVI correct evaluation of the aortic annulus is mandatory to choose the correct prosthesis type and size and(More)
OBJECTIVE Sternal dehiscence after median sternotomy can be a challenging problem in case of multiple fractures or infection. The use of titanium plates is a promising approach for sternal reconstruction. METHODS Titanium plate fixation was used in 15 patients (67+/-5.9 years, 171+/-8.2 cm, 93.6+/-14.9 kg, body mass index 32+/-5 kg/m(2)) with unstable(More)
OBJECTIVES In this prospective evaluation we investigated the accuracy of 64-slice computed tomography angiography (CTA) in an unselected but symptomatic patient population for detection of stenoses in bypass grafts when compared with invasive angiography. BACKGROUND The assessment of significant stenosis in bypass grafts is important for patients with(More)
We successfully implanted a bioprosthetic aortic valve via the right subclavian artery within the framework of the CoreValve transapical aortic valve replacement (TAVR) ReValving (CoreValve, Irvine, CA, USA) clinical trial on November 20, 2007, at the Clinic for Cardiovascular Surgery at the German Heart Center Munich, Technical University Munich. The(More)
On June 26, 2007, the Clinic for Cardiovascular Surgery at the German Heart Center Technical University in Munich successfully implanted a bioprosthetic valve via the apex of the heart within the framework of the CoreValve TAVR ReValving (Corevalve Inc., Irvine, CA, USA) clinical trial. The self-expanding aortic valve prosthesis is primarily designed for(More)
OBJECTIVE We sought to assess the incremental prognostic value of quantitative plaque characterization beyond established CT risk scores. BACKGROUND Several plaque characteristics detectable by coronary computed tomographic angiography (coronary CTA) are thought to be indicative of vulnerable plaques and subsequent cardiac events, particularly low(More)
Prevalence of coronary artery disease (CAD) is high in diabetic patients while diagnosis of early stage of CAD remains demanding. This study evaluates prognostic value of coronary computed tomography angiography (CCTA) for long-term outcome to predict cardiac events in oligosymptomatic diabetic patients. A cohort of 108 consecutive diabetic patients without(More)
We present a case of a migrated ventricular pacing lead after 1 month of implantation. Enhanced computed tomography allowed for the exact diagnosis. Defibrillator lead perforations are widely described. Although most pacemaker lead perforations are usually recognized during or shortly after implantation, late perforations can occur.
