A case report and a literature review of the patients who underwent
surgical repair of an aortic valve injury secondary to nonpenetrating
trauma are presented. Thirty-seven patients (32 male and 5 female patients)
with a median age of 43 years sustained either blunt chest trauma (34
patients) or muscular strain (3 patients) as a cause of injury. Primary
repair was undertaken on 4 patients before 1964 (when the first aortic
valve replacement was performed for this condition) and on 6 other patients
after 1964. In the former group, 2 patients died because of heart failure
and 1 subsequently required a prosthesis. The last patient had an excellent
result at 17 years. In the latter group, 1 patient with a complex lesion
had persistent moderate aortic regurgitation. The 5 remaining patients had
a simple lesion to the valve and showed excellent results on follow-up
evaluation (ranging from 6 months to 6 years). Aortic valve replacement
successfully corrected the valvular dysfunction in 26 patients. Except for
1 case of hemolytic anemia, specific complications of prosthesis were not
encountered, but median follow-up of this review was only 9 months. A
modulated approach to this condition is proposed where primary repair is
selected for cases with a simple tear or avulsion of one cusp.
Intraoperative control of the repair by transesophageal echocardiography
increases the safety of this approach. Valve replacement is indicated for
more complex lesions or for ineffective primary repair as assessed by
intraoperative echocardiography.(ABSTRACT TRUNCATED AT 250 WORDS)
