Patients under Psychiatric Medication Undergoing Cardiac Surgery Have a Higher Risk for Adverse Events.

 The percentage of patients undergoing cardiac surgery under some sort of psychiatric medication (PM) is not negligible. Thus, this study aimed to evaluate a possible impact of preoperative PM on the outcome after cardiac surgery.  A matched case-control study was conducted by including all patients who underwent myocardial revascularization and/or surgical valve operation in our institution from December 2008 till February 2011 by chart review and institutional quality assurance database (QS) analysis.

Minimized extracorporeal circulation is improving outcome of coronary artery bypass surgery in the elderly.

Advanced age is a known risk factor for morbidity and mortality after coronary artery bypass grafting (CABG). Minimized extracorporeal circulation (MECC) has been shown to reduce the negative effects associated with conventional extracorporeal circulation (CECC). This trial assesses the impact of MECC on the outcome of elderly patients undergoing CABG.

Existence of circulating anti-endothelial cell antibodies after heart transplantation is associated with post-transplant acute allograft rejection.

Anti-endothelial cell antibodies (AECA) may be involved in the development of heart allograft rejection. Its detection might be a cheap and noninvasive method to identify high-risk patients. An indirect immunofluorescence method on human umbilical vein endothelial cells was used to investigate the presence of AECAs in 260 pre- and post-transplant serum samples sequentially collected from 34 patients within the first year after heart transplantation (HTX).

Re-exploration for bleeding or tamponade after cardiac surgery: impact of timing and indication on outcome.

Objectives: Re-exploration after cardiac surgery remains a frequent complication with adverse outcomes. The aim of this study was to evaluate the impact of timing and indication of re-exploration on outcome.

Methods: A retrospective, observational study on a cohort of 209 patients, who underwent re-exploration after cardiac surgery between January 2005 and December 2011, was performed.

Impact of age on early outcome after coronary bypass graft surgery using minimized versus conventional extracorporeal circulation.

Background: Objective of this study was to evaluate the impact of age on comparative early outcomes after coronary artery bypass graft surgery (CABG) with minimized (MECC) and conventional extracorporeal circulation (CECC).

Methods: A retrospective age-, gender- and operation-matched cohort analysis between January 2005 and December 2010 with a total of 2274 patients undergoing CABG with MECC (n = 1137; 50%) or CECC was performed. Patients were stratified into 4 groups according to age: <59 years, 60-69 years, 70-79 years, and 80 years of age or older.

Delayed cardiac tamponade after open heart surgery - is supplemental CT imaging reasonable?

Background: Cardiac tamponade is a severe complication after open heart surgery. Diagnostic imaging is challenging in postoperative patients, especially if tamponade develops with subacute symptoms. Hypothesizing that delayed tamponade after open heart surgery is not sufficiently detected by transthoracic echocardiography, in this study CT scans were used as standard reference and were compared with transthoracic echocardiography imaging in patients with suspected cardiac tamponade.

Impact of minimized extracorporeal circulation on outcome in patients with preoperative anemia undergoing coronary artery bypass surgery.

Preoperative anemia and low hematocrit during cardiopulmonary bypass have been associated with worse outcome in patients undergoing cardiac surgery. The minimized extracorporeal circulation (MECC) allows a reduction of the negative effects associated with conventional extracorporeal circulation (CECC). In this study, the impact of the MECC on outcome of anemic patients after coronary artery bypass grafting (CABG) was assessed.

Emergency coronary artery bypass grafting using minimized versus standard extracorporeal circulation--a propensity score analysis.

Background: The impact of minimized extracorporeal circulation (MECC) for emergency revascularization remains controversial.

Methods: A total of 348 patients underwent emergency CABG with MECC (n=146) or conventional extracorporeal circulation (CECC; n=175) between January 2005 and December 2010. Using propensity score matching after binary logistic regression, 100 patients, who underwent CABG with MECC could be matched with 100 patients, who underwent CABG with CECC.

CABG surgery with long coronary endarterectomy of the LAD.

Diffuse atherosclerosis of the anterior descending artery may require unconventional surgical treatment to increase graft flow. A 74-year-old man with severe, diffuse 3-vessel-coronary artery disease was presented to our institution with progredient angina pectoris symptoms. Intraoperatively, the revascularization of the left anterior descending coronary artery (LAD) was technically challenging because of the extremely calcified coronary artery disease; therefore we performed the longest endarterectomy of the LAD that has thus far been described.

Early results of coronary artery bypass grafting with coronary endarterectomy for severe coronary artery disease.

Background: Despite the existence of controversial debates on the efficiency of coronary endarterectomy (CE), it is still used as an adjunct to coronary artery bypass grafting (CABG). This is particularly true in patients with endstage coronary artery disease. Given the improvements in cardiac surgery and postoperative care, as well as the rising number of elderly patient with numerous co-morbidities, re-evaluating the pros and cons of this technique is needed.

Acute aortic dissection type A discloses Corpus alienum.

We report an unusual case of an aortic type A dissection with a corpus alienum which compresses the right ventricle. The patient successfully underwent an aortic root replacement in deep hypothermia with re-implantation of the coronary arteries using a modified Bentall procedure and the resection of the corpus alienum. Intraoperative finding reveals 3 greatly adhered gauze compresses, which were most likely forgotten in the operation 34 years ago.
