Insight Into Kidney Protection by Vacuum-Assisted Venous Drainage in Adult Cardiac Operation - A Multicenter Study.

Background: The relationship between venous congestion and acute kidney injury (AKI) in cardiac surgery after cardiopulmonary bypass has not thoroughly investigated. Vacuum-assisted venous drainage (VAVD) reduces venous congestion, so we hypothesized that it would reduce the incidence of AKI in cardiovascular surgery.

Methods and results: We used a retrospective propensity score-matched analysis to evaluate the effect of VAVD on AKI in adult patients undergoing cardiac surgery.

Therapeutic Effect of Perioperative Mild Hypothermia on Postoperative Neurological Outcomes in Patients with Acute Stanford Type A Aortic Dissection.

Background: Postoperative patients of acute Stanford type A aortic dissection (AAAD) often experience complications consisting of nervous system injury. Mild hypothermia therapy has been proven to provide the therapeutic effect of cerebral protection. We aimed to investigate the therapeutic effects of perioperative mild hypothermia on postoperative neurological outcomes in patients with AAAD.

Use of del Nido cardioplegia in acute aortic dissection surgery.

Objective: Del Nido cardioplegia solution provides a depolarized hyperkalemic arrest lasting up to 60 minutes. Single-dose del Nido cardioplegia solution may offer an alternative myocardial protection strategy to conventional whole blood cardioplegia following acute aortic dissection surgery.

Methods: We retrospectively reviewed 122 consecutive patients with acute aortic dissection undergoing arch reconstruction surgery procedure with cardioplegia arrest from January 2017 to December 2019.

Aortic arch reconstruction: deep and moderate hypothermic circulatory arrest with selective antegrade cerebral perfusion.

Objective: To compare the effects of moderate and deep hypothermic circulatory arrest (DHCA) with selective antegrade cerebral perfusion (SACP) during aortic arch surgery in adult patients and to offer the evidence for the detection of the temperature which provides best brain protection in the subjects who accept aortic arch reconstruction surgery.

Methods: A total of 109 patients undergoing surgery of the aortic arch were divided into the moderate hypothermic circulatory arrest group (Group I) and the deep hypothermic circulatory arrest group (Group II). We recorded the data of the patients and their cardiopulmonary bypass (CPB) time, aortic clamping time, SACP time and postoperative anesthetized recovery time, tracheal intubation time, time in the intensive care unit (ICU) and postoperative neurologic dysfunction.

[Surgical treatment of post-infarction left ventricular aneurysm: clinical analysis].

Objective: To explore the clinical experiences, efficacies and postoperative left ventricular remodeling changes of surgical ventricular reconstruction in the treatment of post-infarction left ventricular aneurysm.

Methods: The investigators reviewed retrospectively the clinical data, operative approaches and follow-up outcomes of consecutive 194 patients with post-infarction left ventricular aneurysm, who underwent surgical ventricular reconstruction between January 1997 and December 2009. There were 54 cases in the linear group and 137 cases in the endoventricular patch plasty group.

[Clinical application of extracorporeal membrane oxygenation for severe heart failure during peri-operative period of end-stage cardiopathy].

Objective: To summarize the clinical effect and experience of extracorporeal membrane oxygenation (ECMO) support for severe heart failure during peri-operative period of end-stage cardiopathy.

Methods: From June 2007 to July 2010, 6 patients with severe heart failure during peri-operative period of end-stage cardiopathy received ECMO support. The changes in the hemodynamics and outcome of the patients during the use of ECMO were investigated.

[Aortic arch operation under deep hypothermic circulatory arrest].

Objective: To summarize the surgical experience of aortic arch operation under deep hypothermic circulatory arrest.

Methods: 22 patients suffering from aortic dissection or descending aorta aneurysm with the involvement of aortic arch received operation under deep hypothermic circulatory arrest. Eight patients underwent ascending aorta and partial aortic arch replacement, one patient received aortic root, ascending aorta, and partial aortic arch replacement, 2 patients received ascending aorta and total arch replacement, 2 patients received aortic valve replacement plus ascending aorta and partial aortic arch replacement, 8 patients underwent ascending aorta and total arch replacement plus elephant trunk technique (stunted elephant trunk used in 6 cases), and 1 patient received left partial aortic arch and descending aorta replacement.

Is the use of cardiopulmonary bypass for isolated coronary artery bypass an independent predictor of mortality and morbidity in patients with severe left ventricular dysfunction?

Background: Patients presenting with severe left ventricular dysfunction (SLVD) undergoing conventional coronary artery bypass grafting (CCABG) are at an increased risk of perioperative mortality and morbidity. The aim of this study was to assess the risk factors responsible for mortality and morbidity among patients with SLVD by comparing CCABG and off-pump coronary artery bypass surgery (OPCAB).

Methods: We retrospectively evaluated 186 consecutive patients with SLVD who underwent coronary artery bypass grafting (CABG), including 102 by CCABG and 84 by OPCAB.

[Surgical treatment of obstructive hypertrophic cardiomyopathy with ventricular septal myectomy concomitant mitral valve replacement].

Objective: To summarize the experiences and results of ventricular septal myectomy concomitant mitral valve replacement (MVR) for obstructive hypertrophic cardiomyopathy (OHCM).

Methods: From January 2000 to June 2007, 22 patients of OHCM with moderate or severe mitral regurgitation underwent concomitant ventricular septal myectomy concomitant MVR. There were 20 male and 2 female patients.
