Management of Accidental and Iatrogenic Foreign Body Injuries to Heart- Case Series.

Accidental and iatrogenic foreign body injuries to heart require immediate attention and its timely management is cornerstone to the life of an individual. We describe in detail five cases of Accidental and iatrogenic foreign body injuries to heart encountered between January 2013 and July 2016. Our series included the following: needle stick injury to the right atrium (1 case) retained catheter fragments in the distal main pulmonary artery (1 case), right ventricle injury during catheterisation study (1 case), right ventricle injury during permanent pacemaker lead placement (1 case), device migration in atrial septal defect closure (1 case). Foreign bodies were removed from the cardiac cavities when the patient presented with features of infection (1 case), cardiac tamponade (2 case), anxiety (1 case), and haemodynamic instability (1 case). The management of accidental and iatrogenic foreign body injuries to heart requires immediate attention. Foreign bodies in the heart should be removed irrespective of their location and symptomatology. Asymptomatic foreign bodies diagnosed immediately after the injury with associated risk factors should be removed; asymptomatic foreign bodies without associated risks factors or diagnosed accidentally after the injury also need surgical intervention to allay fears of anxiety in patient and their relatives, to prevent any late complications and also for medico-legal purpose.

Ideal Hematocrit to Minimize Renal Injury on Cardiopulmonary Bypass.

OBJECTIVE: Renal dysfunction after cardiopulmonary bypass (CBP) ranges from subclinical injury to established renal failure requiring dialysis. The pathophysiology is multifactorial, and recently, hemodilution during CBP has been thought to be an important determinant of postoperative renal injury. In this study, we attempted to assess the independent effect of hemodilution on renal function. We also aimed to identify the optimal hematocrit where hemodilution-induced renal injury is minimal. METHODS: A prospective observational study was conducted on 200 patients between February 2012 and July 2013. One hundred fifty patients were included in the study group, who were further subdivided on the basis of lowest hemodilution as mild hemodilution (>25%), moderate hemodilution (21%-25%), and severe hemodilution (<21%) categories. The primary outcome of the study was renal outcome measure, which was assessed by comparing the creatinine clearance across the groups. RESULTS: The creatinine clearance decreased over a period in all three groups. When compared with mild or moderate hemodilution, the reduction in creatinine clearance was significantly higher in the group with severe hemodilution (P ≤ 0.0001). However, there was no significant difference in creatinine clearance reduction between the mild and moderate hemodilution groups (P = 0.813; 95% confidence interval, -8.41 to 10.68). CONCLUSIONS: Based on our observations, we would like to propose that a hematocrit of 21% should be considered the critical threshold. Hematocrit below this value of 21% during CBP is associated with the most significant deterioration in renal function.

An Unusual Cause of Cardiac Tamponade during Cardiac Catheterization Study.

Introduction. Catheter-based diagnostic and therapeutic procedures are rapidly advancing. However, catheter related complications sometimes become life threatening. Cardiac tamponade is a rare but serious complication of this procedure. We have summarized one cardiac tamponade pejoration due to secondary coronary vessels laceration by the implanted pericardial drainage. Case report. A 4-year-old baby having Tetralogy of Fallot was posted for diagnostic catheterization study. Patient was induced with sevoflurane and spontaneous respiration was maintained. After catheter insertion to RV, dye was injected through the catheter which rapidly spread into the pericardial cavity indicating right ventricle perforation. Immediately, blood was aspirated under transthoracic echocardiographic guidance and hemodynamics started improving. For the provision of quick access to aspirate further collection, an intrapericardial sheath was inserted after multiple attempts. Patient's condition started deteriorating again. TTE revealed again some collection and it was increasing gradually. On exploration, it was found that there was continuous bleeding from a lacerated epicardial vessel which contributed to the pericardial collection leading to further tamponade effect. This second iatrogenic injury complicated the management of the first iatrogenic cardiac perforation and, thereby, created a life-threatening situation which needed immediate surgical exploration. Discussion. Usual cause of tamponade after right ventricular perforation is bleeding from the RV, but in our case the second tamponade was not due to bleeding from the RV, but was rather from new laceration injury of epicardial vessels which was remained undiagnosed till exploration.

Holt-oram syndrome in adult presenting with heart failure: a rare presentation.

Holt-Oram syndrome is a rare inherited disorder involving the hands, arms, and the heart. The defects involve carpal bones of the wrist and the thumb and the associated cardiac anomalies like atrial or ventricular septal defects. Congenital cardiac and upper-limb malformations frequently occur together and are classified as heart-hand syndromes. The most common amongst the heart-hand disorders is the Holt-Oram syndrome, which is characterized by septal defects of the heart and preaxial radial ray abnormalities. Its incidence is one in 100,000 live births. Approximately three out of four patients have some cardiac abnormality with common associations being either an atrial septal defect or ventricular septal defect. Herein, we report a rare sporadic case of Holt-Oram syndrome with atrial septal defect with symptoms of heart failure in a forty-five-year-old lady who underwent emergency cardiac surgery for the symptoms.
