Geometric mismatch between homograft (allograft) and native aortic root: a 14-year clinical experience.
We evaluated the effect of homograft/native aortic root geometric matching and mismatching on valve survival and myocardial remodeling. ⋯ The aortic homograft offers an excellent long-term clinical result. A mismatched homograft is a risk factor for postoperative aortic incompetence, reinfection with pseudoaneurysmal formation and reoperation for the freehand subcoronary implantation technique during the first 7 years of the postoperative period. It is prudent therefore to avoid mismatched homografts and use rather a properly sized stentless xenograft if a root replacement is not indicated.

Surgical intervention for pulmonary tuberculosis: analysis of indications and perioperative data relating to diagnostic and therapeutic resections.
To analyze the data on patients operated on for pulmonary tuberculosis (TB) with (Group I) or without (Group II) a correct TB diagnosis and preoperative anti-TB treatment. ⋯ Patients without a correct preoperative TB diagnosis underwent more extensive parenchyma resection. Postoperative complications increased when acid-fast bacilli were present. The lack of preoperative anti-TB treatment did not involve a higher risk of minor complications, but death occurred only in this group.
