Intracardiac aorto-right atrial tunnel

Aortic root enlargement does not increase the surgical risk and short-term pati...

Objective: To analyze the short-term outcome of aortic root enlargement (ARE) using death and adverse events as end points. Methods: From January 1999 through December 2009, 3339 patients were subjected to aortic valve replacement (AVR). A total of 678 were considered to have small aortic roots (SARs) in which an aortic prosthesis size 21mm or smaller was implanted. ARE using a bovine pericardial patch was perf...

Long-term follow-up of elderly patients subjected to aortic valve replacement w...

We propose to analyse the long-term follow-up in patients older than 65 years of age who received a mechanical valve in the aortic position, using death and prosthetic-related complications as endpoints. From April 1988 to December 1995, 144 consecutive patients 65-75 years of age (mean 67.7+/-2.5) were enrolled. Total duration of follow-up was 1663 patient-years (median 13.0 years) and was complete for 99% of ...

Diagnostic value of surgical lung biopsy: comparison with clinical and radiolog...

OBJECTIVE: To determine overall and disease-related accuracy of the clinical/imagiological evaluation for pulmonary infiltrates of unknown aetiology, compared with the pathological result of the surgical lung biopsy (SLB) and to evaluate the need for the latter in this setting. METHODS: We conducted a retrospective review of the experiences of SLB in 366 consecutive patients during the past 5 years. The presump...

Acute Mitral Regurgitation due to Ruptured ePTFE Neo-chordae

Chordal replacement with expanded polytetrafluoroethylene (ePTFE) sutures has proven to be a simple, versatile, and durable technique for the treatment of prolapsed cusps causing mitral valve regurgitation. ePTFE is known for its strong resistance to tension, and is judged to be unbreakable under physiological conditions. Herein are reported two cases of rupture of synthetic chordae tendineae; the possible caus...
