Comparative StudyLong-term impact of radial artery harvest on forearm function and symptoms: a comparison with leg vein.
The radial artery (RA) has gained popularity as a conduit for coronary artery bypass surgery despite a paucity of patient-centered analysis of long-term quality of life after its removal. We sought to characterize forearm function and symptoms after RA harvest and compare these with those associated with saphenous vein (SV) removal. ⋯ RA harvesting is associated with high patient satisfaction and less scar discomfort than SV removal. Overall, functionality declines with time, and a small proportion of patients seem to experience forearm pain and numbness. However, this is not different than in those without artery removal and may therefore be unrelated to the effects of surgery.

Multicenter Study Clinical TrialDynamic annuloplasty for mitral regurgitation.
The MiCardia DYANA annuloplasty system (MiCardia Corp, Irvine, Calif) is a nitinol-based dynamic complete ring that allows modification of the septal-lateral diameter under transesophageal echocardiography guidance in the loaded beating heart after mitral valve repair. Shape alteration is induced by radiofrequency via detachable activation wires. This multicenter study reports the first human experience with this device. ⋯ The implantation of the new dynamic annuloplasty ring allows for safe mitral valve repair. The option of postrepair modification of the septal-lateral diameter by radiofrequency may further optimize repair results.

Routine left atrial appendage ligation during cardiac surgery may prevent postoperative atrial fibrillation-related cerebrovascular accident.
The aim of the study was to determine whether routine left atrial appendage ligation in cardiac surgery would reduce the risk of postoperative atrial fibrillation-related cerebrovascular accident. ⋯ Although postoperative atrial fibrillation remains a common complication of cardiac surgery, there was a significant decrease in the incidence of postoperative cerebrovascular accidents since routine ligation of the left atrial appendage was undertaken. This has been found to be a safe adjunct to a wide variety of cardiac procedures and therefore deserves further study by a larger randomized controlled trial.

Comparative StudyImpact of T status and N status on perioperative outcomes after thoracoscopic lobectomy for lung cancer.
We sought to evaluate the effect of tumor size, location, and clinical nodal status on outcomes after thoracoscopic lobectomy for lung cancer. ⋯ Thoracoscopic lobectomy for lung cancers that are central, clinically node positive, or >3 cm does not confer increased morbidity compared with peripheral, clinical N0 cancers that are <3 cm.
