Supports safety of upper hemisternotomy in LV dysfunction; leaves open randomized confirmation of equivalence or benefit.
Does aortic valve replacement via an upper hemisternotomy reduce operative mortality and morbidity compared to full sternotomy in patients with left ventricular dysfunction (EF ≤ 40%)?
Minimally invasive aortic valve replacement via upper hemisternotomy is safe and yields similar operative mortality and morbidity to full sternotomy in patients with left ventricular dysfunction.
