Survey of ultrasound training in obstetrics and gynecology residency training programs in the United States.

A survey was mailed to all 292 nonmilitary obstetrics and gynecology residency programs in the United States. The extent and type of ultrasound training and degree of compliance with recommended guidelines was evaluated from the 230 (78.8%) responses. Criteria for evaluation were based on guidelines from the American Institute of Ultrasound in Medicine Joint Task Group on Training for Diagnosis in Obstetrical and Gynecological Ultrasound, and on recommendations from The American College of Obstetricians and Gynecologists. Although almost 98% of respondents claimed to have ultrasound "training" in their programs, more than 55% indicated no resident experience with either reading or writing ultrasound reports, and only 39% of program chiefs claimed greater experience than 200 ultrasound scans per resident over four years. Overall, it appears that current suggested guidelines are not being met.

Data Collection

Comparative study of Björk-Shiley and Starr-Edwards prostheses for aortic valve replacement.

Thirty-nine patients received aortic valve replacement prostheses. The 19 patients who received Starr-Edwards (SE) caged-ball valve prostheses and the 20 patients who received Björk-Shiley (BS) tilting-disc valve prostheses were followed up for a mean period of 20 and 19 mo, respectively. The cumulative mortality rate was 5.3% in the SE group and 15% in the BS group. The clinical improvement was more remarkable in the BS than in the SE series. Major thromboembolic complications developed in three patients in each group, and two patients in each group developed infectious endocarditis. Tests for intravascular hemolysis indicated a higher rate in the SE than in the BS group. The serum haptoglobin levels were 39 +/- 22 and 102 +/- 63 g/dl (mean +/- SD), respectively (P less than 0.001). The hemoglobin level was 12.4 +/- 1.8 g/dl in the SE group and 13.4 +/- 0.6 g/dl in the BS group (P less than 0.03). The BS tilting-disc valve caused less hemolysis and the smaller size led to greater clinical improvement.
