Key result
Partial upper sternotomy is linked to less chest pain and better pulmonary function vs median sternotomy.
Why the study?
Pain and pulmonary function differences after partial upper versus complete sternotomy for aortic valve surgery were evaluated to inform surgical approach benefits.
Cohort (n=31)

Should not yet change sternotomy choice for AVR; extends limited evidence but leaves open need for RCTs.
OBJECTIVE: The aim of this study was to evaluate pain and pulmonary function after partial upper versus complete sternotomy for aortic valve surgery. METHODS AND RESULTS: In a prospective study of 31 adult patients, 15 individuals underwent aortic valve replacement via partial upper sternotomy, and 16 patients were operated on by means of a full median sternotomy. Chest pain was assessed at rest, after spirometry and coughing, using the visual analogue scale and a structured questionnaire. Forced expiratory volume at I second and forced vital capacity were measured by a hand-held spirometer. Minimal-access patients had less postoperative pain and improved pulmonary function in comparison with conventional aortic valve replacement. After partial upper sternotomy, the postoperative chest pain was confined to the sternal area, while after standard sternotomy a more generalized chest pain occurred. Differences in pain scores could still be demonstrated one month after discharge. CONCLUSIONS: This study suggests that partial upper sternotomy improves pulmonary function and reduces pain in comparison with standard full sternotomy.

CANDAELE et al. (2003) conducted a cohort in Aortic Valve Disease (n=31). Partial upper sternotomy vs. Full median sternotomy was evaluated on Postoperative chest pain (at rest, after spirometry, and coughing) and pulmonary function. Partial upper sternotomy reduced generalized postoperative chest pain and improved pulmonary function compared to standard full median sternotomy, with differences persisting one month after discharge.
