BACKGROUND Although the MAZE procedure allows for the recovery of sinus rhythm and left atrial (LA) mechanical function in the great majority of patients with chronic atrial fibrillation (AF), the effects of MAZE on the precise LA geometry and wall motion remain to be elucidated. We hypothesized that LA size and mechanical function in patients with chronic(More)
based on an established rationale supported by experimental laboratory and observational field studies, and a number of epidemiological studies. Meta-analyses have been carried out to derive exposure–re-sponse relationships that can be used for quantitative health impact assessments. 91 Noise-induced sleep disturbance constitutes an important mechanism on(More)
OBJECTIVES We evaluated the durability of aortic valve preservation with root reconstruction for acute type A aortic dissection (AAAD). METHODS From January 2002 to March 2011, 140 patients [70 males, 68 ± 12 (SD) years] underwent emergency operation for AAAD. The aortic valve was preserved and one or more Valsalva sinuses were reconstructed. Techniques(More)
