Study acronym	MiniStern Trial
Study objectives	MiniStern is a pragmatic, prospective randomised controlled trial comparing upper mini-sternotomy to full median sternotomy as a surgical approach to first time isolated aortic valve replacement (AVR).
Ethics approval(s)	MREC approved (ref: 09/H0301/58)
Health condition(s) or problem(s) studied	Topic: Cardiovascular, Generic Health Relevance and Cross Cutting Themes; Subtopic: Cardiovascular (all Subtopics), Generic Health Relevance (all Subtopics); Disease: Cardiovascular, Surgery
Intervention	Comparing upper mini-sternotomy to full median sternotomy as a surgical approach to first time isolated aortic valve replacement (AVR).
Intervention type	Procedure/Surgery
Primary outcome measure(s)	Total length of stay in hospital for the index AVR operation measured in days
Key secondary outcome measure(s)	1. Fitness for discharge 2. Health related quality of life and patient satisfaction at baseline, 6 weeks, 6 months and 12 months using the 36-item short form health survey (SF-36) and Coronary Revascularization Outcome Questionnaire - Coronary Artery Bypass Graft (CROQ-CABG) 3. Heart function (LVEF) by echocardiography at baseline, day of discharge and 6 months post surgery 4. Procedure time: total theatre time, cross clamp time, cardiopulmonary bypass time, blood loss, blood transfusion 5. Respiratory function (forced expiratory volume in one second [FEV1]) by hand held spirometry at baseline, day 4, day of discharge, 6 weeks and 6 months
