Unguarding of an atrioventricular valvar orifice is a rare form of congenital heart disease that requires staged functionally univentricular palliation. Unguarding of the mitral valvar orifice has previously been reported in the setting of mirror-imaged atrial arrangement. We report a neonate with unguarding of the mitral valvar orifice in the setting of usual atrial arrangement, but with discordant atrioventricular connections and pulmonary atresia.

Peripherally inserted central catheters are commonly used for intravascular access in low birth weight neonates. Here, we describe a case of transcatheter retrieval of an embolised peripherally inserted central catheter line in the right ventricle extending to the left pulmonary artery in a preterm very low birth weight baby. To the best of our knowledge, this is the first case where transcatheter retrieval of embolised peripherally inserted central catheter line has been done from the left pulmonary artery in such a very low birth weight preterm neonate. Although retrieval of foreign body is common in adults and older children, very few case reports have documented successful retrieval of embolised peripherally inserted central catheter line in very low birth weight neonates using interventional techniques. Most of the cases in literature reported retrieval of an indwelling umbilical venous catheter rather than a peripherally inserted central catheter line as in our case. Also, none of these cases had the embolised fragment retrieved from the left pulmonary artery. This approach was technically very challenging as we were taking care of a 5-day old preterm neonate born at 32 weeks of gestation having very low birth weight (1100 g) with features of clinical sepsis, coagulopathy, and embolised catheter fragment extending from right ventricle to left pulmonary artery. The procedure was uneventful without any complication and the catheter was retrieved successfully.

Ductal stenting in late presenters with transposition of great arteries with intact ventricular septum retrains the left ventricle before arterial switch operation. However, the experience is limited for its efficacy and safety. This study aims to highlight the efficacy and safety of ductal stenting for retraining the left ventricle. Eight children with transposition of great arteries-intact ventricular septum and regressed left ventricle underwent ductal stenting. Serial echocardiographic measurements of left ventricle shape, mass, volume, free wall thickness, and function were done, and arterial switch operation was performed once the left ventricle was adequately prepared. Post-operative outcome in terms of duration of mechanical ventilation, ICU stay, and improvement in left ventricle function were monitored. The procedure was successful in all patients. Babies were divided into two groups on basis of age at ductal stenting (group 1 age less than 90 days and group 2 age more than 90 days) and were evaluated for the degree of left ventricle retraining as evidenced by echocardiographic parameters and post-operative variables. The left ventricle posterior wall thickness and mass index after ductal stenting increased significantly in both the groups. Postoperatively, one baby of group two expired after seven days due to severe left ventricle dysfunction. Rest babies had an uneventful post-operative ICU stay with no statistical difference in the duration of invasive mechanical ventilation or ICU stay. On six-month follow-up, all surviving babies were doing well with normal left ventricle function. Ductal stenting is a good alternative measure as compared to surgical procedures for left ventricle retraining in transposition of great arteries with regressed left ventricle.

Early weight trends after cardiac surgery in infants from low- and middle-income countries where the majority are undernourished have not been defined. We studied the early post-operative weight trends to identify specific factors associated with early weight loss and poor weight gain after discharge following congenital heart surgery in consecutive infants undergoing cardiac surgery at a referral hospital in Southern India. This was a prospective observational study. Weights of the babies were recorded at different time points during the hospital stay and at 1-month post-discharge. A comprehensive database of pre-operative, operative, and post-operative variables was created and entered into a multivariate logistic regression analysis model to identify factors associated with excessive early weight loss after cardiac surgery, and poor weight gain following hospital discharge. The study enrolled 192 infants (mean age 110.7 ± 99.9 days; weight z scores - 2.5 ± 1.5). There was a small but significant (p < 0.001) decline in weight in the hospital following surgery (1.6% decline (interquartile range -5.3 to +1.7)); however, there was substantial growth following discharge (26.7% increase (interquartile range 15.3-41.8)). The variables associated with post-operative weight loss were cumulative nil-per-oral duration and cardiopulmonary bypass time, while weight gain following discharge was only associated with age. Weight loss is almost universal early after congenital heart surgery and is associated with complex surgery and cumulative nil-per-oral duration. After discharge, weight gain is almost universal and not associated with any of the perioperative variables.
