Agenesis of pulmonary artery.

We enjoyed reading the report by Dr. Kochiadakis and coworkers (June 2002).1 We would like to point out, however, that we have reported on a similar case of a 51-year-old woman with pulmonary hypertension and agenesis of the right pulmonary artery.2 Her pulmonary artery pressure was 68/24 mm Hg, as measured by right heart catheterization. The diagnosis of agenesis was confirmed by conventional pulmonary angiography as well as by magnetic resonance angiography, which also showed a common origin for both the common carotid arteries and an aberrant right subclavian artery, originating in the aortic arch distal and proceeding to the left subclavian artery. Left heart catheterization revealed communicating vessels between the left circumflex coronary artery and the right pulmonary circulation (Fig 1). Similar to the report by Kochiadakis et al,1 our patient did not have any evidence of myocardial ischemia due to these abnormal vessels, and surgical intervention was not undertaken. Although this report is not cited in MEDLINE, it was submitted and published in the case report section of the Chest 2000 International Meeting.
