title: Anatomy of the proximal coronary arteries as a risk factor in primary repair of common arterial trunk.
abstract: The objective of this study was to investigate whether the proximal coronary arterial anatomy is a risk factor in surgical treatment of common arterial trunk, with special focus on the value of preoperative angiocardiography. A retrospective analysis was performed of all 22 patients who underwent primary surgical repair of the common arterial trunk, with a mean follow-up of 5.1 years. In 18 patients preoperative angiocardiography was performed. Anatomical features (angiocardiographical, surgical as well as post-mortem) of the proximal coronary arteries were investigated. With standard biplane angiocardiography single and dual coronary arterial systems could adequately be distinguished. However, the position of the coronary orifices in relation to the sinus of Valsalva could not adequately be identified. Three patients had coronary abnormalities without surgical consequences. In 2 cases the surgical approach had to be modified due to the coronary anatomy. Early mortality was 23% (5/22) and was correlated with worse functional class (p < 0.05) and earlier date of operation (p < 0.05). Late mortality was 5% (1/22). Five patients were reoperated, without mortality. Fourteen surviving patients are in functional class I, and 2 in class II. A further improvement of the surgical therapy of common arterial trunk might be provided by adequate appreciation of the proximal coronary arterial anatomy at surgery.
