Randomized Controlled Trial Comparative StudyEffect of atrioventricular conduction prolongation on optimization of paced atrioventricular delay for biventricular pacing after cardiac surgery.
Atrioventricular conduction prolongation (AVCP) in cardiac pacing is measurable and results primarily from delayed atrial conduction. Noninvasive methods for measuring atrial conduction are lacking. Accordingly, AVCP was used to estimate atrial conduction and investigate its role on the paced atrioventricular delay (pAVD) during biventricular pacing (BiVP) optimization. ⋯ AVCP varies widely after cardiopulmonary bypass, affecting optimum pAVD. Failure to correct for this can result in the selection of inappropriately short and potentially deleterious pAVDs, especially when nominal pAVD is used, causing BiVP to appear ineffective.

Comparative StudyTechnical aspects of anesthesia and cardiopulmonary bypass in patients undergoing totally thoracoscopic cardiac surgery.
The use of fast-track general anesthesia in patients undergoing nonrobotically assisted and totally thoracoscopic cardiac surgeries has not been previously reported previously. ⋯ Cardiopulmonary bypass for totally thoracoscopic cardiac surgery can be established through the femoral artery and femoral vein. With fast-track anesthesia, early extubation in the operating room can be achieved in more than one third of patients.

Comparative StudyEchocardiographic evaluation of systolic and diastolic function: a preoperative study of correlation with serum NT-proBNP.
The authors hypothesized that preoperative N-terminal probrain natriuretic peptide (NT-proBNP) correlates well with longitudinal strain measurements and with Doppler measurements of diastolic function. ⋯ A correlation was found between plasma levels of NT-proBNP and speckle tracking ultrasound strain measurements by an easily employed method applicable in the anesthesia and preoperative settings. In addition, the well-established marker of diastolic function, E/E', correlated well with NT-proBNP, whereas the E/A ratio failed to show any association.

Comparative StudyTreatment with β-blockers and incidence of post-traumatic stress disorder after cardiac surgery: a prospective observational study.
The aim was to investigate perioperative factors associated with the development of post-traumatic stress disorder (PTSD) in patients who underwent cardiac surgery. ⋯ These findings suggest that the use of β-blockers might be protective against the development of PTSD in women after cardiac surgery.
