Long-Term Prognostic Value and Serial Changes of Plasma N-Terminal Prohormone B-Type Natriuretic Peptide in Patients Undergoing Transcatheter Aortic Valve Implantation
The objectives of this study were to evaluate the baseline values and serial changes of N-terminal prohormone B-type natriuretic peptide (NT-proBNP) after TAVI, its related factors, and prognostic value. A total of 333 consecutive patients were included, and baseline, procedural, and follow-up (median 20 months, interquartile range 9 to 36) data were prospectively collected. Systematic NT-proBNP measurements were performed at baseline, hospital discharge, 1, 6, and 12 months, and yearly thereafter. Baseline NT-proBNP values were elevated in 86% of the patients (median 1,692 pg/ml); lower left ventricular ejection fractio...

Frequency, Determinants and Prognostic Implications of Infectious Complications After Transcatheter Aortic Valve Implantation
This study included 298 consecutive patients from 2 centers who underwent TAVI from November 2005 to November 2011. IHI during the hospital stay was defined on the basis of symptoms and signs assessed by the attending physician in the cardiac care unit or medium care unit in combination with all technical examinations performed to confirm infection. IHI after TAVI was observed in 58 patients (19.5%): urinary tract infections in 25 patients (43.1%), pneumonia in 12 patients (20.7%), and access-site infections in 7 patients (12.1%). In 12 patients (20.7%), the site of infection could not be determined, and 2 patients (3.4%) ...
