Regarding "Bifurcating Aneurysm of the Left Main Coronary Artery Involving Left Anterior Descending and Left Circumflex Arteries"

In this paper by Rahmatulla and colleagues (Angiology 50:417-420, 1999) the authors repeatedly claim that their paper is the first to report such an aneurysm. Actually, several articles dealing with left main coronary artery aneurysm 1,2 involving the left anterior descending and circumflex arteries, have been published already. In one paper2 a series of 22 patients with an aneurysm of the left main coronary artery was presented. Detailed angiographic characteristics of these aneurysms were described including the finding of 12 aneurysms extending into another major coronary artery with the following distribution : seven patients into both left anterior descending and circumflex arteries and five patients into the left anterior descending artery. As Rahmatulla et al failed to adequately review the pertaining literature, they also failed to describe specific morphologic-angiographic characteristics of left main aneurysms including the saccular and fusiform shapes, the frequent presence of calcification within these aneurysms (32%), the prevalence of associated three vessel coronary artery disease (73%), the unique aneurysm-related phenomenon of a pseudo-filling defect during contrast injections, as well as the interesting association with abdominal aortic
