Cardiac surgery in low birth weight infants: current outcomes.
Low birth weight (LBW) is a risk factor for mortality in neonatal and infant heart surgery. The purpose of this study was to determine the contemporary outcomes and risk factors of cardiac surgery in low weight babies. The records of 75 consecutive infants weighing <2.5 kg having heart surgery were reviewed. ⋯ Age, prematurity, preoperative mechanical ventilation, prostaglandins, non-cardiac organ dysfunction, extra-cardiac malformations, perioperative extracorporeal membrane oxygenation (ECMO), and type of procedure were not associated with significant differences in mortality. Cardiac surgery in LBW infants can be performed with low early and mid-term mortality. LBW infants with chromosomal/genetic anomalies have a higher risk.

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.
