A Case of Pericardial Decompression Syndrome Following Surgical Pericardial Fluid Drainage.

Pericardial decompression syndrome (PDS) is a rare and serious complication that follows often-initially-uncomplicated pericardial drainage in patients with pericardial effusion and tamponade physiology. The pathophysiology of PDS is not yet completely understood, although several mechanisms have been postulated. In this report, we present a case of PDS in a 70-year-old male with end-stage renal disease (ESRD) after he underwent a surgical pericardial window for drainage of a moderate pericardial effusion with tamponade physiology. This case provides further evidence that rapid pericardial decompression, notably with pericardiotomy, can lead to acute life-threatening low cardiac output heart failure, particularly in patients with underlying cardiac risk factors. Early recognition, diagnosis, and supportive treatment in the ICU are crucial for improving survival rates in these patients.

Cytomegalovirus reactivation in left ventricular assist device patients: case series and literature review.

BACKGROUND: Cytomegalovirus (CMV) reactivation after placing left ventricular assist device (LVAD) is not a well-known entity with few cases reported in the literature. Here, we are presenting three cases of CMV reactivation after placing LVAD. A literature review of all reported cases in the literature was done. CASE SUMMARY: Three cases of advanced heart failure with reduced ejection fraction (Stage D9) had placed (LVAD) at the American University of Beirut Medical Center, a tertiary care centre in Lebanon. Within the first 2 weeks after LVAD implantation, the three patients spiked a high-grade fever for which sepsis workup was done, and antibiotics were initiated. Despite the escalating antibiotic regimens, the three patients had a persistent high-grade fever. The negative cultures and the continuous fever prompted an investigation for other causes of fever. Therefore, CMV polymerase chain reaction in blood was performed and revealed high titres. Patients received a full course of treatment with ganciclovir. The fever and the CMV titres declined after completing the antiviral therapy with better clinical outcomes. This raises the concern of CMV reactivation in LVAD patients. DISCUSSION: This case series and literature review highlight the epidemiology, incidence, and management of CMV reactivation among LVAD patients. Awareness about this clinical entity should be raised, especially with the increase of LVAD surgeries.

Arrhythmias in Neonates and Infants at a Tertiary Care Center.

Background Limited data about arrhythmias in neonates and infants are coming out from the Middle East. Objectives To evaluate different types of arrhythmias in neonates and infants at the American University of Beirut Medical Center (AUBMC), a tertiary care center in Lebanon, with the focus on the nature of arrhythmia, treatment modalities and relation to surgery. Methods Data were collected retrospectively from the hospital records. We included all neonates and infants presenting to AUBMC between 2013 and 2017. Collected data included: the type of arrhythmia, the treatment modality used and its success, the need for additional modes of treatment, the relationship to congenital heart diseases, and the cardiac surgeries performed. Results Of 16,346 subjects admitted to AUBMC between 2013 and 2017, 90 subjects developed arrhythmias that required medical intervention. The most frequent types of arrhythmias were supraventricular tachycardia (62.22%), junctional ectopic tachycardia (13.33%), complete heart block (7.78%), atrial flutter (5.56%), multifocal atrial tachycardia (3.33%), Wolf Parkinson White Syndrome (3.33%), non-sustained ventricular tachycardia (2.22%), sinus pause (1.11%), and premature ventricular contractions (1.11%). Bivariate analysis showed a significant difference between arrhythmias not related to cardiac surgery and arrhythmias related to cardiac surgery in terms of the type of arrhythmia developed, the presence of congenital heart defect, prematurity, and electrolyte disturbances (P-value <0.005). However, multivariate logistic regression showed no significant difference between the two groups after adjustment for the significant variables (P-value > 0.05). Conclusion There is a significant difference between arrhythmias not related to cardiac surgery and arrhythmias related to cardiac surgery in neonates and infants at AUBMC. However, the difference disappears after adjusting for different variables.
