RESUMEN

Iatrogenic coronary artery dissection is a rare complication seen in 0.07% of coronary procedures. Presentations of this condition vary, ranging from signs of myocardial ischemia to rarer presentations of ventricular arrhythmias. We present a rare case of a 55-year-old patient with native aortic valve endocarditis who developed right coronary artery dissection (RCAD) in the immediate post-op period presenting with refractory ventricular fibrillation (VF). Emergency coronary angiogram revealed an extensive RCAD extending from the ostium to the mid-vessel as the cause of VF. A consensus between the cardiologists and the cardiac surgeons led to an emergency right coronary artery bypass graft (CABG) that resolved the VF. This case illustrates a rare presentation of iatrogenic RCAD and the successful management of the same. We highlight the importance of prompt detection via angiography in patients suspected of having coronary artery dissection and showcase the successful implementation of emergency CABG in a patient with unstable haemodynamics.

RESUMEN

Aortitis is a pathological term that refers to the inflammation of one or more layers of the aortic wall. It is associated with a wide spectrum of inflammatory diseases of infectious and non-infectious origins, and often present with vague clinical findings and non-specific laboratory results that can model other entities. As a result, aortitis may not form part of the initial workup and appropriate treatment can be delayed or missed. Therefore, imaging modalities are required to assess for inflammation and structural changes in the aorta to support or exclude the diagnosis of aortitis. This review presents current literature on the imaging modalities utilized in the diagnosis and management of aortitis, which surgeons and physicians should be familiar with for providing optimal patient care.

RESUMEN

Ischaemic optic neuropathy is a rare but serious complication post cardiopulmonary bypass in cardiac surgery patients. It presents with visual loss either unilaterally or bilaterally, and it can be anterior or posterior in type depending on the segment of the optic nerve involved. In non-ocular surgery patients, the most common type is called non-arteritic ischaemic optic neuropathy. We report a case of bilateral non-arteritic ischaemic optic neuropathy following coronary artery bypass grafting and mitral valve surgeries and review the published literature for the aetiology, management and prognosis of this rare complication.

RESUMEN

OBJECTIVE: This retrospective study aimed to explore the role of Glasgow Aneurysm Score (GAS) and Hardman Index (HI) in predicting outcome after elective endovascular aneurysm repair (EVAR). METHODS: All 71 patients who underwent elective EVAR in a single centre over 9 years were reviewed. Clinical data were used to classify patients into the three standard GAS tertiles and to score patients according to the HI. RESULTS: Fifty-one patients scored > or = 77 according to GAS. Actual and predicted mortality in this group were 3.9% and 9.3%. Seventeen patients scored between 69 and 77 with actual and predicted mortality of 0% and 4.1%. Three patients scored less than 69 with actual and predicted mortality of 0% and 2.4%. Ten patients scored > or = 3 on the HI with actual and predicted mortality of 10% and 100%, respectively. Twenty-four patients scored 2 with actual and predicted mortality of 4.2% and 55%. Twenty-seven patients scored 1 with actual and predicted mortality of 0% and 28%, respectively. Ten patients scored 0 with actual and predicted mortality of 0% and 16%, respectively. The chi(2) test showed extremely significant p value of 0.0001 in case of HI, and p value of 0.0800 for GAS, slightly less significant, probably due to the small sample size. CONCLUSION: Contrary to their role in ruptured and open aortic aneurysm repair, GAS and HI overestimate both mortality and morbidity following EVAR and are poor predictors of outcome.
