Multicenter Study
Residual and Progressive Aortic Regurgitation After Valve-Sparing Root Replacement: A Propensity-Matched Multi-Institutional Analysis in 764 Patients.
Residual/progressive aortic regurgitation (rAR, pAR) after valve-sparing aortic root replacement (V-SARR) can lead to reoperations. We sought to characterize risk factors of mild rAR and pAR after V-SARR in a multicenter cohort. The effect of additional cusp repair on valve function was analyzed using propensity matching. ⋯ The incidences of rAR and pAR are considerable after V-SARR. Patients should be operated on before large aneurysms are present. New onset AR after an initially good functional result is more likely after an additional cusp repair, while rAR and pAR are not influenced by cusp repair.

Comparative Study
Surgical Strategy and Outcome for Aortic Root in Patients Undergoing Repair of Acute Type A Aortic Dissection.
This study evaluated the relevance of our indication of aortic root operations for acute type A aortic dissection and compared early and long-term outcomes of emergency type A aortic dissection operations between patients who underwent aortic root operations and those who did not. ⋯ Simultaneous aortic root operations significantly reduced the incidence of late aortic root events. The dissection of 2 or more sinuses of Valsalva was associated with a late aortic root event in patients who did not undergo aortic root operations.

Association of Peak Changes in Plasma Cystatin C and Creatinine With Death After Cardiac Operations.
Acute kidney injury is a risk factor for death in cardiac surgical patients. Plasma cystatin C and creatinine have different temporal profiles in the postoperative setting, but the associations of simultaneous changes in both filtration markers compared with change in only one marker with prognosis after hospital discharge are not well described. ⋯ Elevations in creatinine postoperatively are more common than elevations in cystatin C. However, elevations in cystatin C appeared to be associated with a higher risk of death after hospital discharge.

Extensive literature has proved that the Nuss procedure leads to permanent remodeling of the chest wall in pediatric patients with pectus excavatum (PE). However, limited long-term follow-up data are available for adults. Herein, we report a single-institution experience in the management of adult PE with the Nuss procedure, evaluating long-term outcomes and overall patient satisfaction after bar removal. ⋯ Favorable long-term results can be achieved with the Nuss procedure in adults. However, postoperative pain may require a more aggressive analgesic regimen, and it may be the overriding factor in the patient's perception of the quality of the postoperative course.

This study evaluated whether risk factors for sternal wound infections vary with the type of surgical procedure in cardiac operations. ⋯ Risk factors for sternal wound infections after cardiac operations vary with the type of surgical procedure. In patients undergoing valve operations or combined operations, procedure-related risk factors (revision for bleeding, duration of operation) independently predict infection. In patients undergoing CABG, not only procedure-related risk factors but also bilateral internal thoracic artery harvest and patient characteristics (diabetes, chronic obstructive pulmonary disease, obesity, female sex) are predictive of sternal wound infection. Preventive interventions may be justified according to the type of operation.
