|Abstract:||Saccular coronary aneurysms are defined as aneurysms with the transverse dimension at least 1.5 times the longitudinal dimension. Out of 3,200 coronary angiograms reviewed, there were 22 patients (20 males) with saccular coronary aneurysms (totalling 25 aneurysms). The morphology of the aneurysms, the extent and severity of associated coronary lesions, the clinical profile and follow-up data of these patients were analysed. Aneurysms were located in left main coronary artery 3 (12%), left anterior descending coronary artery 13 (52%), right coronary artery 5 (20%) and left circumflex 4 (16%). There were 5 large aneurysms (> 15 mm in diameter) (1 in left main coronary artery, 2 each in right coronary artery and left anterior descending coronary artery) averaging 32 mm in size. Fifteen aneurysms had significant coronary artery stenosis located proximal to it, supporting the theory of post-stenotic dilatation as the aetiology of aneurysm formation. Two patients had associated muscle bridges distal to the aneurysm; 20 had atherosclerotic coronary artery disease and one had coronary artery ectasia. Five patients were lost to follow-up, which ranged from 1 year to 19 years (mean 5.3 +/- 4.1 years). No patient had history suggestive of rupture of the aneurysm on follow-up. Two patients had myocardial infarction in the territory of the vessel with the aneurysm. Rest of the patients were in NYHA class I/II. One large right coronary artery aneurysm was subjected to aneurysmectomy due to symptoms of tricuspid valve obstruction. One left main coronary artery aneurysm measuring 12 mm, on follow-up of 19 years increased in size to 45 mm, in addition the patient developed a right coronary artery aneurysm. Coronary risk factor profiles in the 20 patients with atherosclerotic coronary artery disease and aneurysms were similar to age- and sex-matched control population with atherosclerotic coronary artery disease without aneurysms.|
