A 55-year-old man developed severe mitral regurgitation with persistent fungal infective endocarditis 8 months after coronary artery bypass grafting with a left internal mammary artery and 2 saphenous veins, as well as mitral valve repair with a prosthetic ring. Echocardiography demonstrated severe mitral regurgitation and a valvular vegetation. Computed tomography coronary arteriography indicated that all grafts were patent and located intimately close to the sternum. Median resternotomy was not attempted due to the risk of injury to the bypass grafts, and therefore, a right anterolateral thoracotomy approach was utilized. Mitral valve replacement was performed with the patient under deep hypothermia and ventricular fibrillation without aortic cross-clamping. The patient`s postoperative course was uneventful. Thus, right anterolateral thoracotomy may be a superior approach to mitral valve surgery in patients who have undergone prior coronary artery bypass grafting.

The aim of this study was to investigate if there was a link between the relaxant responses in saphenous vein (SV) and internal mammary artery (IMA) segments obtained from patients undergoing coronary artery bypass grafting and the patients' cardiovascular risk factors. Endothelium-(in)dependent relaxations were assessed by isometric tension studies. Endothelium-dependent relaxant responses were greater in IMA than SV and gender, smoking profile and history of hypertension but not diabetes appeared to have an influence on these responses. Endothelium-dependent relaxant responses in both IMA and SV were greater in males than females and relaxant responses in IMA segments were attenuated in smokers, whereas the opposite effect was noted in SV segments. Endothelium-dependent relaxant responses in SV were lower in patients with hypertension. Endothelium-independent relaxant responses were greater in IMA than SV. Endothelium-independent responses were greater in male patients' SV segments, but gender played no role in IMA segments. Diabetes had no effect on endothelium-independent responses in IMA, but SV segments from diabetic patients had greater responses. Neither conduit's endothelium-independent response was affected by hypertensive status. The relationship between risk factor status and endothelial responses is multifactorial, with gender, hypertension, diabetes and smoking status all contributing.
