Comparison of Immediate Outcomes of Pulmonary Valve-Sparing and Transannular Patch Techniques for Correction of Tetralogy of Fallot.

Objectives: This study primarily aimed to compare the mechanical ventilation durations between pulmonary valve-sparing and transannular patch repair techniques in the surgical correction of Tetralogy of Fallot. Secondary objectives included comparison of demographic characteristics, cardiopulmonary bypass parameters, postoperative vasoactive inotrope requirements, incidence of cardiac conduction abnormalities, echocardiographic findings, intensive care unit and hospitalisation durations, reoperations rates, morbidity and mortality between the 2 approaches.

Methods: This retrospective cohort study was conducted at the Royal Hospital, Muscat, Oman, between January 2016 and December 2019.

Comparing flow and pulmonary artery growth post-patent ductus arteriosus stenting in patients with ductal-dependent pulmonary flow using 4D magnetic resonance imaging.

Aims: The 4D magnetic resonance imaging (4D-flow MRI) provides a qualitative and quantitative assessment of cardiovascular structures and processes. 4D-flow MRI was used to study pulmonary flow in post-patent ductus arteriosus (PDA) stent insertion in duct-dependent pulmonary flow neonates at baseline (PDA stent insertion) and after 6 months, and also, to evaluate the effect of flow dynamics on the growth of pulmonary arteries (PAs).

Methods And Results: This prospective observational study included neonates with ductus arteriosus-dependent pulmonary circulation who underwent ductal stenting between June 2021 and November 2022.

Extubation Failure in Infants with Modified Blalock-Taussig Shunt: The Incidence, Predictors, and Outcomes.

Objectives: Infants with congenital heart diseases often require mechanical ventilation and a prolonged intensive care unit (ICU) stay due to complex cardiopulmonary complications. The primary objective of the study was to determine the incidence and predictors of tracheal extubation failure in infants undergoing modified Blalock-Taussig shunt (MBTS). The secondary objective was to evaluate if extubation failure was associated with increased mortality and longer ICU and hospital stays.

Knowledge and Awareness of Prostate Cancer Among Omani Men Attending a Teaching Hospital.

Prostate cancer is ranked as the fourth most prevalent cancer in the world and the second most common cancer affecting men. In Oman, prostate cancer is one of the most common cancers among men, with the majority of prostate cancer patients presenting in the more advanced stages of the disease. Public awareness of the risk factors, symptoms and emphasising the importance of seeking early medical attention could help to improve the outcomes and survival rates of prostate cancer patients.

Bilateral Diaphragmatic Paralysis Following Paediatric Cardiac Surgery: Experience of four cases at the Royal Hospital, Muscat, Oman.

Bilateral diaphragmatic paralysis (BDP) is a rare complication of paediatric cardiac surgery. We report four children who developed BDP following cardiac surgery who were managed at the Royal Hospital, Muscat, Oman, between 2009 and 2014. All four children suffered severe respiratory distress soon after extubation and required re-intubation within two hours.

Mechanical cause for acute left lung atelectasis after neonatal aortic arch repair with arterial switch operation: Conservative management.

Respiratory complications due to mechanical obstruction of the airways can occur following pediatric cardiac surgery. Clinically significant intrathoracic vascular compression of the airway can occur when extensive dissection and mobilization of arch and neck vessels is involved as in repair of interrupted aortic arch. This case report describes a neonate who underwent interrupted aortic arch repair along with an arterial switch operation and developed a left lung collapse immediately after tracheal extubation.

Two Cases of Pneumatoceles in Mechanically Ventilated Infants.

Pulmonary pneumatocele is a thin-walled, gas-filled space within the lung that usually occurs in association with bacterial pneumonia and is usually transient. The majority of pneumatoceles resolve spontaneously without active intervention, but in some cases they might lead to pneumothorax with subsequent hemodynamic instability. We report two cases presented to the pediatric intensive care unit at the Royal Hospital, Oman with pneumatoceles.

Late presentation of congenital diaphragmatic hernia: a case report.

Delayed herniation of the abdominal contents through a congenital diaphragmatic hernia may occur beyond the neonatal period. This report describes a 9-week-old female baby who presented with excessive crying, irritability and respiratory distress secondary to late presentation of left-sided congenital diaphragmatic hernia. The chest radiograph showed tension gastrothorax.

Severe Pertussis Pneumonia managed with Exchange Transfusion.

We describe in this case report one month old baby admitted to our Pediatric Intensive Care Unit (PICU) with severe pertussis pneumonia. The baby was deteriorating despite being on supportive management including High Frequency Oscillator ventilation (HFOV). However, she showed dramatic improvement after exchange blood transfusion (ET) and was discharged home.

Late Onset Central Hypoventilation Syndrome due to a Heterozygous Polyalanine Repeat Expansion Mutation in the PHOX2B Gene.

This report describes a 6 year old girl with late onset central hypoventilation syndrome due to a heterozygous polyalanine repeat expansion mutation in the PHOX2B gene. This report aims to increase the awareness of this condition among physicians to allow earlier clinical and genetic diagnosis and management of cases of unexplained hypoventilation.
