Profile

About Dr. Salim

Dr. Salim is a Senior Consultant in Paediatric Interventional Cardiology at Muscat Private Hospital, with more than 21 years in the diagnosis and treatment of heart conditions that children are born with or develop in childhood.

Dr. Salim helped build paediatric cardiology in Oman, establishing a comprehensive service and introducing catheter-based treatment of structural heart defects in children procedures that in many cases avoid or postpone open-heart surgery. His practice runs from fetal life through to adulthood, and he continues to look after adults born with heart defects, a group who need lifelong specialist follow-up and who often lose track of it after childhood.

He works across both diagnosis and treatment: echocardiography, including fetal and transoesophageal studies, electrocardiography and cardiac CT on the diagnostic side, and diagnostic and interventional cardiac catheterisation on the other. His experience covers straightforward defects and complex ones, and he works closely with cardiac surgeons in deciding which route is right for a particular child.

Dr. Salim is President of the Oman Heart Association and a board member of the Gulf Heart Association. He has been Director of the National Heart Center since 2015, previously led the Child Health Department at the Royal Hospital for five years, and sat on the Paediatric Scientific Committee of the Oman Medical Specialty Board from 2006 to 2021. He has lectured on congenital heart disease at national and international conferences and published in peer-reviewed journals.

With families, Dr. Salim sets out the diagnosis and the plan in plain terms, including what will happen at each stage and what the alternatives are a diagnosis of a heart defect in a child is frightening, and parents make better decisions when they understand it.

Common Questions

Frequently Asked Questions

Dr. Salim treats heart conditions in children — both those a child is born with, such as holes in the heart, narrowed valves and coarctation of the aorta, and those acquired in childhood, such as Kawasaki disease, rheumatic heart disease and inflammation of the heart muscle. He also sees adults who were born with a heart defect, and assesses babies whose heart looks abnormal on an antenatal scan.
Usually not. Most murmurs found in children are what doctors call innocent or functional — the normal sound of blood moving through a healthy heart, often more audible when a child has a fever or is growing fast. They need no treatment and disappear with time. An echocardiogram can usually settle the question in one visit, and being told there is nothing wrong is the commonest outcome of that appointment.
Not necessarily. A number of defects that once required surgery can now be closed or opened with a catheter passed through a vein or artery in the leg, leaving no chest scar and with a much shorter recovery. Others still need surgery, and some need nothing at all. Which applies depends on the exact defect, its size and position, and your child's age and size. Dr. Salim works with the cardiac surgical team on these decisions rather than making them alone, and will explain why a particular route is being recommended.
No. Many small ventricular septal defects close on their own during the first years of life, and small atrial septal defects may never need intervention. Treatment is recommended when the defect is large enough to strain the heart or lungs, or is causing symptoms. Where the advice is to watch and wait, that is a real plan and not a delay — it means regular review with scans to check nothing is changing.
It is a detailed ultrasound of the baby's heart carried out during pregnancy, usually from around 18 to 22 weeks. It is offered when a routine scan raises a question about the heart, when there is a family history of congenital heart disease, in some twin pregnancies, and where the mother has diabetes or certain other conditions. Finding a defect before birth allows the delivery and the first days of life to be planned properly, which matters a great deal for the more serious conditions.
Because adults born with a heart defect need a specialist who knows congenital anatomy and the surgery that was done in childhood — which is a different body of knowledge from adult coronary cardiology. Many people repaired as children stop attending follow-up in their teens or twenties and only re-present years later. If you were operated on as a child, or told you had a hole in the heart or a narrowed valve, it is worth being reviewed even if you feel entirely well.

They are generally low in experienced hands, but they are not nil. Possible problems include bleeding or damage to the blood vessel used for access, disturbance of heart rhythm, movement of a device after placement, and the risks of the anaesthetic. Serious complications are uncommon. Dr. Salim will go through the specific risks for your child's procedure, and what the alternative is if you decide against it, before you are asked to consent.
