Comparison of Mid-Term Graft Patency between On-Pump and Off-Pump Coronary Artery Bypass Grafting.

Background: Multiple studies have compared on-pump coronary artery bypass (ONCAB) grafting with off-pump coronary artery bypass (OPCAB) grafting, but the optimal surgical strategy has yet to be established. Furthermore, there is limited evidence regarding mid-term graft patency rates.

Methods: Between April 2001 and March 2014, 365 consecutive patients underwent isolated coronary artery bypass grafting (CABG; male: 75%; mean age: 69 ± 10 years).

Hemodynamic deterioration after aortic valve replacement in a patient with mixed systemic amyloidosis.

We report a case of hemodynamic deterioration after aortic valve replacement in a patient with mixed systemic amyloidosis. A 77-year-old male with severe aortic valve stenosis and 19 years hemodialysis underwent aortic valve replacement. Postoperatively, the patient died of hemodynamic deterioration.

Visualization of collateral channels with coronary computed tomography angiography for the retrograde approach in percutaneous coronary intervention for chronic total occlusion.

Background: There have been no reports about the diagnostic ability of coronary computed tomography angiography (CTA) in evaluating collateral channels used for retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Objective: We investigated the ability and diagnostic accuracy of coronary CTA compared with invasive coronary angiography to detect collaterals used in retrograde CTO PCI and to compared the success rates for wire crossing between collaterals that are detectable and not detectable in coronary CTA.

Methods: We retrospectively reviewed data from 43 patients (55 collaterals) who underwent coronary CTA and PCI for CTO with the retrograde approach.

[Efficacy of Multi-vessel Coronary Artery Bypass Grafting for Patient with Low Left Ventricular Ejection Fraction].

The efficacy of multi-vessel coronary artery bypass grafting (CABG) for low left ventricular ejection fraction (LVEF) is controversial. We assessed 31 consecutive low LVEF patients who underwent CABG in our hospital from April 2007 to September 2014. Seventeen patients underwent CABG with distal anastomosis 5 or less (group A), and 14 patients underwent CABG with distal anastomosis 6 or more (group B).

Temporary ventricular overdrive pacing for electrical storm after coronary artery bypass grafting.

A 57-year-old man who had been receiving chemotherapy for multiple myeloma complained of chest pain and was diagnosed with coronary artery disease. Coronary artery bypass grafting without cardiopulmonary bypass was performed smoothly, and extubation was done in the operating room. The next evening, cluster of ventricular tachycardia and fibrillation triggered by ventricular premature contractions occurred and required multiple electrical defibrillations.
