Impact of unintentional coronary angiography on outcomes of emergency surgery in acute type A aortic dissection: a retrospective study.

Background: This study investigated the impact of coronary angiography on outcomes of emergency operation in acute type A aortic dissection (ATAAD) patients who were initially misdiagnosed as an acute coronary syndrome.

Methods: From October 2016 to April 2019, 129 patients underwent emergency operation for ATAAD in our institution, including 21 patients (16.3%, coronary angiography group) who received preoperative coronary angiography without knowledge of the ATAAD, and the rest 108 did not (Non-coronary angiography group).

[Analysis of risk factors in elderly patients with renal dysfunction undergoing off-pump coronary artery bypass grafting].

Objective: To analyze the risk factors in the patients over 65 years old undergoing off-pump coronary artery bypass grafting (OPCAG) as grouped by postoperative creatinine clearance rate (Ccr).

Methods: A total of 462 consecutive patients over 65 years old undergoing OPCAG from January 2007 to December 2008 were recruited. They were divided into 3 groups by renal functions: normal, minor injury and moderate-severe injury.

[Effect of pericardial suction blood re-transfusion in off-pump coronary artery bypass grafting on inflammatory cytokines, myocardial injury and pulmonary function].

Objective: To investigate the effect of pericardial suction blood re-transfusion in off-pump coronary artery bypass grafting (CABG) on inflammatory cytokines, myocardial injury and lung function.

Methods: 31 patients of off-pump CABG were divided into two study groups (OPCABG1 group and OPCABG2 group) according to the amount of pericardial suction blood re-transfusion beyond or less than 600 ml. 13 patients of on-pump CABG were control group.
