title: [Excision of the calcified mitral valve with ultrasound scalpel].
abstract: Mitral valve excision using ultrasound device has not been a routine procedure yet. We used an ultrasonic scalpel for the excision of the calcified mitral valves, which shorten operation time. Further, this technique permits an excision of the valve without applying traction or elevation of the valve from the level of the annulus. This method was first tested on twenty fresh porcine hearts. Subsequently, this technique was carried out with very good results in 15 consecutive patients with calcified or scarred, and distorted mitral valves. Histological samples were taken from the excised human and porcine valves. In porcine histological specimens the destructive effect of the ultrasonic scalpel was measured of an average of 0.7 mm (minimum 0.5 mms, maximum 0.8 mms). However, in the human heart, this effect was an average of 1.1 mms (minimum 0.6 mms, maximum 2.2 mms). There were no early or late complications observed in any case. The authors recommend this technique for excision of calcified mitral valves in cardiac surgery.
