Comparative StudyEuroSCORE directed intraaortic balloon pump placement in high-risk patients undergoing cardiac surgery--retrospective analysis of 267 patients.
Intraaortic balloon pump replacement (IABP) is the most widely used circulatory assist device today and is utilized in a wide range of serious cardiovascular conditions. We examined the effects on mortality of pre-, intra-, or postoperative IABP support in patients undergoing cardiac surgery compared to high-risk patients without IABP support. ⋯ Preoperative IABP support is indicated in high-risk non-emergency patients. The benefit of preoperative IABP insertion in emergency patients and intra- and postoperative IABP support still remains controversial and needs to be elucidated in further prospective, randomized studies.

Comparative StudyBiochemical markers of myocardial injury in the pericardial fluid of patients undergoing heart surgery.
The purpose of this study was to compare cardiac markers in the pericardial fluid and serum in order to evaluate preoperative myocardial injury. Thirty patients were divided into three groups. The first group (AVR; n=10) received an aortic valve replacement. ⋯ Preoperative pericardial and serum cTnI were significantly higher in the ACS than in AVR and SA groups (P<0.01). Postoperative pericardial concentration of all markers was significantly higher (P<0.01) than in serum in all groups. We conclude that preoperative pericardial accumulation of cTnI may reflect subclinical injury which may not be demonstrated by the usual laboratory tests.

Repair of aortic arch and the impact of cross-clamping time, New York Heart Association stage, circulatory arrest time, and age on operative outcome.
Aortic arch replacement is associated with high morbidity and mortality. ⋯ Elderly patients and patients with high NYHA class need close postoperative monitoring in the ICU. A short circulatory arrest and aortic clamp time do not extend the LOS in ICU or in the hospital.

Case ReportsSurgical repair of aortico-left ventricular tunnel arising from the left aortic sinus.
Aortico-left ventricular tunnel is a rare congenital cardiac defect, which bypasses the aortic valve via the paravalvar connection from the left ventricle to the aorta. In most of the cases, the tunnel arises from the right aortic sinus. We herein report a case of aortico-left ventricular tunnel, of which the aortic orifice was arising from the left aortic sinus, requiring special attention for avoiding left coronary artery injury at the time of surgical repair.
