Cerebral monitoring in patients undergoing carotid endarterectomy using a triple assessment technique.
Selective shunting during carotid endarterectomy (CEA) is advocated to reduce shunt related stroke. Cerebral monitoring is essential for temporary carotid shunting. Many techniques are available for cerebral monitoring, however, none is superior to monitoring the patient's neurological status (awake testing) while performing the procedure under local anaesthesia (LA). Cerebral oximetry (CO) and trans-cranial Doppler (TCD) has previously been used to show the adequacy of cerebral circulation in patients undergoing CEA. The aim of this study is to assess the reliability of CO and TCD in predicting the need for shunting compared to the awake testing. ⋯ TCD is less accurate than CO in predicting the need for carotid shunting during CEA. A combination of both methods does not add to the accuracy of detecting the need for carotid shunting.

Comparative StudyBeating heart versus conventional mitral valve surgery.
The present study aimed to compare the results of beating heart technique and conventional mitral valve surgery (MVS). ⋯ This study concluded that beating heart MVS can be performed successfully, particularly for patients at higher risk which will lead to increased morbidity and mortality in postoperative period.

Levels of N-terminal-pro-brain natriuretic peptide in congenital heart disease surgery and its value as a predictive biomarker.
To explore the value of N-terminal-pro-brain natriuretic peptide (NT-ProBNP) as a predictive biomarker of postoperative cardiovascular surgery. ⋯ NT-ProBNP concentration is dependent on time during the perioperative period, it peaks at 24 hours and depends on the preoperative value and CPB length. A high peptide level before surgery is an independent predictor of prolonged stay in intensive pediatric care.
