ABSTRACT
OBJECTIVE: To better understand the outcome of the bicuspid aortic valve (BAV) after valve-sparing root replacement, we evaluated BAV function after its preservation at the time of the ascending aorta (AA) repair. PATIENTS AND METHODS: From January 1, 1994, through March 31, 2002, BAVs were preserved during repair of AA aneurysms in 21 patients (mean ± SD age, 45±12 years; 13 males). We reviewed the clinical and surgical records of these patients for baseline characteristics, operative procedures, and data at latest follow-up. RESULTS: The primary indication for operation was AA enlargement (median diameter, 55 mm; range, 43–65 ram) in 18 patients and severs aortic regurgitation (AR) in 3 patients. Preoperatively, the BAV exhibited mild or moderate stenosis in 5 patients (mean gredient, 25 mm Hg; range, 19–34 mm Hg), moderate AR in 2, and severe AR in 3. Aortic valve repair was performed in 11 patients. Seventeen patients had excision and graft replacement of the enlarged AA, and 4 patients had primary AA repair. There were no perioperative deaths. Moderate or severe AR was relieved in all patients early pestoperatively and during follow-up (median, 2.5 years; maximum, 7.6 years). One patient required aortic valve replacement at 4.8 years for AR. An additional patient had recurrent, severe AR but was asymptomatic and has not undergone reoperation. CONCLUSION: Repair of diseased BAVs or preservation of functionally normal BAVs during surgery for AA aneurysms has a low perioperative risk, and early results are encouraging. Additional observation is necessary to determine whether this strategy has real advantages over early aortic valve replacement.

    Mandibular second premolars with three canals (Type V, Vertucci) and separate foramina are very rare. The anatomy of the pulp chamber floor in these premolars usually reveals one lingual and two buccal orifices at the same level. This case report describes a second premolar with three canals and...

    Adequate penetration of sealers in dentinal tubules reduce microleakage. For resin based sealers root canal should be kept moist and for nonresin, dry. The aim of this study was to evaluate the clear-cut clinical steps on how to accomplish an ideal dentinal root canal surface. Methods: Thirty...
