Asymptomatic Giant Aneurysm of the Left Anterior Descending Coronary Artery: A Case Report and Review of the Literature.

The most common cause of coronary artery aneurysms is atherosclerosis, which is associated with over 50% of all aneurysms diagnosed in adults. Although patients can be asymptomatic throughout their lives, giant coronary artery aneurysms can manifest themselves as myocardial infarction, aneurysmal rupture, and sudden cardiac death as well. Herein, we describe an asymptomatic patient with numerous risk factors and a positive cardiopulmonary exercise test who was admitted to the cardiology clinic for coronary angiography. A giant coronary artery aneurysm (3.0×2.0 cm in diameter) in the left anterior descending coronary artery and significant stenosis in both left and right coronary arteries were found. After discussing possible treatment options, the hospital's heart team recommended the surgical resection of the aneurysm and double coronary artery bypass graft. Four years after the cardiac surgery, at the time of writing the current manuscript, the patient is still in good condition and with no symptoms.

Vojvodinascore--local system for cardiac operative risk evaluation.

INTRODUCTION: The aim of the study was to investigate the prognostic value, sensitivity and specificity of both the logistic and additive European System for Cardiac Operative Risk Evaluation (as well as the European System for Cardiac Operative Risk Evaluation II and to assess the necessity for developing a local outcome prediction model in cardiac surgery. MATERIAL AND METHODS: The research included 406 consecutive patients who had undergone cardiac surgical procedures at Institute of Cardiovascular Diseases of Vojvodina from January 2012 to July 2012. The authors compared the predicted mortality according to the additive and logistic European Systems for Cardiac Operative Risk Evaluation, the new European System for Cardiac Operative Risk Evaluation II and the observed mortality (30 days after surgery). RESULTS: The difference between the predicted and observed mortality regarding the whole group of 406 operated cardiac patients was not statistically significant for the additive European System for Cardiac Operative Risk Evaluation (p = 0.081) and the European System for Cardiac Operative Risk Evaluation II (p = 0.164), but it was statistically significant for the logistic European System for Cardiac Operative Risk Evaluation (p = 0.031). The areas under the receiver operating characteristic curves are statistically different from 0.5 for both models (additive and logistic European System for Cardiac Operative Risk Evaluation), as well as for the European System for Cardiac Operative Risk Evaluation II. However, the proper classification of the patients has not been observed since their sensitivity and specificity are not satisfactory. CONCLUSION: The additive and logistic European Systems for Cardiac Operative Risk Evaluation overestimate while the European System for Cardiac Operative Risk Evaluation II underestimates the risk in cardiac surgery. We believe that a locally derived model would be of great use in the everyday clinical practice since it would faithfully illustrate the actual state of patient population of the region where it was developed. At the same time it would provide the accurate prediction of surgical outcome.
