Reverse left ventricular remodelling after aortic valve replacement for severe aortic insufficiency.

Objectives: The goal of this study was to investigate the long-term outcome of aortic valve replacement (AVR) for severe aortic insufficiency with a focus on pre- and postoperative left ventricular (LV) function to explore predictive factors that influence the recovery of LV function and clinical outcome.

Methods: A total of 478 patients who underwent AVR for pure severe aortic insufficiency were grouped according to the preoperative echocardiographical LV ejection fraction (EF): low (LO) EF <35% (n = 43), moderate EF 35-50% (n = 150) or normal EF >50% (n = 285).

Results: Actuarial survival at 10 years post-AVR was 64% with a LO EF, 92% with a moderate EF and 93% with a normal EF (P = 0.

Surgical Treatment of Jejunal Artery Aneurysm.

Introduction: A jejunal artery aneurysm (JAA) is rare and has few specific symptoms. Endovascular repair is widely used in the treatment of jejunal artery aneurysms; however, some patients still require open repair.

Report: A 59 year old man underwent open surgery with resection of the aneurysm and reconstruction using a saphenous vein graft.

Efficacy of regional saturation of oxygen monitor using near-infrared spectroscopy for lower limb ischemia during minimally invasive cardiac surgery.

Lower limb ischemia with an occlusive cannula is a potential complication of minimally invasive cardiac surgery (MICS). We evaluated intraoperative local oxygen supply-demand balance by monitoring regional saturation of oxygen (rSO) using near-infrared spectroscopy (NIRS), and analyzed the correlation between cannula size and fluctuation range of rSO. Fifty-four patients undergoing MICS surgery using femoral artery cannulation from April 2015 to August 2016 were enrolled.
