Randomized Controlled Trial Clinical Trial
Reduction of the inflammatory response in patients undergoing minimally invasive coronary artery bypass grafting.
The aim of this prospective study was to determine whether the inflammation-associated clinical morbidity as well as the subclinical markers of the inflammatory response are reduced in patients who undergo minimally invasive coronary artery bypass grafting without cardiopulmonary bypass. ⋯ These data suggest that patients who undergo minimally invasive coronary artery bypass grafting have a significant reduction in the systemic inflammatory response, postoperative morbidity, and hospital stay compared with patients who undergo conventional coronary artery bypass grafting with cardiopulmonary bypass.

Comparative Study
Influence of ascending versus descending balloon counterpulsation on bypass graft blood flow.
Mechanical circulatory assistance is frequently needed in postcardiotomy patients to support the failing heart. A balloon catheter called SupraCor (ABIOMED Cardiovascular, Inc, Danvers, MA) has been developed and is similar to the existing intraaortic balloon pump with the exception of placement in the ascending versus the descending thoracic aorta. This investigation compared the effects of SupraCor versus standard intraaortic balloon pump on internal mammary artery and venous conduit bypass graft blood flow. ⋯ The results demonstrate that counterpulsation with an ascending aortic balloon significantly increases coronary bypass graft flow in both internal mammary artery and venous conduits. In contrast, counterpulsation with a descending aortic balloon did not alter coronary bypass graft flow.

Case Reports
Echocardiography allows safer venous cannulation during excision of large right atrial masses.
Excision of large right atrial masses requires bicaval cannulation and cardiopulmonary bypass. Safe venous cannulation can be accomplished only by knowing the exact intracavitary location and extension of the mass to avoid fragmentation. Transthoracic echocardiography and intraoperative transesophageal echocardiography, although helpful, cannot always define the exact intracavitary relationships of the tumor. ⋯ We propose the routine use of both intraoperative transesophageal and epicardial echocardiography in guiding venous cannulation for safe excision of large right atrial masses.

Randomized Controlled Trial Comparative Study Clinical Trial
Inflammatory mediators in adults undergoing cardiopulmonary bypass: comparison of centrifugal and roller pumps.
The nonocclusive centrifugal pump is used for cardiopulmonary bypass (CPB) and mechanical cardiac assistance. This study examined its impact on proinflammatory cytokine release. ⋯ This study confirms the proinflammatory nature of CPB in adults and demonstrates that use of the centrifugal pump induces a greater systemic inflammatory response than use of the standard roller pump.

Randomized Controlled Trial Clinical Trial
Prophylactic tranexamic acid and epsilon-aminocaproic acid for primary myocardial revascularization.
The efficacy of prophylactic epsilon-aminocaproic acid and tranexamic acid to reduce transfusions after primary myocardial revascularization was evaluated in a teaching hospital context. ⋯ We conclude that either high-dose tranexamic acid or epsilon-aminocaproic acid effectively reduces transfusions in patients undergoing primary, elective myocardial revascularization.
