Right minithoracotomy (RT) and lower hemisternotomy (HS) have each been associated with improved short-term outcomes; however, these approaches have not been directly compared to each other.

Outcomes of interest were postoperative complications, long-term survival, and freedom from mitral reoperation. A Cox proportional hazard model was used to compare RT and HS to a reference cohort of full-sternotomy cases. Total observation time was 9,901 patient-years and mean follow-up time was 12.2 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Mean age was 58\u00b112 years in the RT group and 56\u00b113 years in the HS group ( P = 0.2). The RT group had longer bypass (143 minutes vs. 112 minutes; P &lt; 0.001) and cross-clamp times (99 minutes vs. 78 minutes; P &lt; 0.001) compared with the HS group. There were no differences in operative mortality or 30-day outcomes. Survival at 5, 10, and 15 years was 99% (96-100), 92% (85-100), and 69% (30-100) in the RT group and 98% (97-99), 92% (90-94), and 89% (86-92) for HS ( P &lt; 0.9). There were no differences in risk-adjusted survival between RT, HS and full sternotomy.
