Intraoperative localization of ground-glass opacities is difficult because they are not easy to palpate and may be invisible at radioscopy. Therefore, various techniques have been developed to improve intraoperative localization of these lesions, allowing an adequate surgical resection. The aim of this study is to report two cases of preoperative localization of ground-glass opacities through computed tomography-guided placement of a metallic clip inside the lesion and to discuss this new technique in comparison with those previously described.

Ischemia-reperfusion injury occurs during coronary artery bypass graft operations. Strategies are needed to lower the extent of damage. ⋯ This review provides a look at potential mechanisms involved in remote ischemic preconditioning, experimental evidence supporting it, clinical studies that support and negate it, and potential reasons for differences between clinical studies. With remote ischemic preconditioning having the potential to better clinical outcomes in patients undergoing coronary artery bypass graft operations, a large clinical trial needs to be undertaken to better assess its practical clinical application.

Minimally invasive (MI) approaches to mitral valve surgery (MVS) and surgical ablation for atrial fibrillation (AF) are now performed routinely, and avoidance of aortic manipulation and cardioplegic arrest may further simplify the procedure. We present our experience with MI fibrillatory cardiac operations without aortic cross-clamping for MVS and AF ablation. ⋯ We demonstrated that low operative mortality and low stroke rate with MI fibrillating cardiac operations without cross-clamping allows for MVS and AF ablation. Our results suggest that the MI fibrillating heart approach is safe and effective.
