Abstract Objective Silent brain lesions are known to occur after coronary artery bypass grafting (CABG). The aim of this study was to seek the incidence rate, the influence of procedures, and their impact on the postoperative course. Methods From July, 2016 to April, 2018, 104 consecutive patients undergoing elective and isolated first-time CABG (65 off-pump and 39 on-pump) were enrolled. New brain lesions were evaluated by brain magnetic resonance imaging both before and after CABG.. Postoperat...
Objectives While reports which focus on the outcomes of conservative treatments for acute type A aortic dissection in patients over the age of 80 are worth considering, recently many studies have reported improved outcomes of surgical treatment. Accordingly, we analyzed the outcomes of surgical and conservative treatments for acute type A aortic dissection with patent false lumen in patients over the age of 80.
Several reports demonstrated positive effects of processing residual cardiopulmonary bypass volume using a cell salvage device in conventional open heart surgery via sternotomy on hemostasis. The present study aimed to investigate whether cell salvage processing has the same effects on postoperative blood loss and transfusion in minimally invasive cardiac surgery. Between July 2015 and April 2018, 80 consecutive patients undergoing minimally invasive aortic valve replacement via right anterolate...
Here, we demonstrate the details of annular decalcification using an ultrasonic aspirator in minimally invasive aortic valve replacement for aortic stenosis. In our debridement procedure, the aortic valve leaflets are excised with enough valve tissue left, not just at the annulus. The invisible annulus is exposed by traction of the remnant valve tissue, and the annular calcifications are scraped off using an ultrasonic aspirator. After an annular decalcification, the remnant valve tissue was com...
