Cardiac Catheterization And Percutaneous Coronary Intervention (PCI)
Cardiac catheterization is used to investigate the structure and function of the heart. Coronary Angiogram is used to investigate for any narrowing of the coronary arteries (arteries that supply blood to heart muscle). When indicated, percutaneous coronary intervention (PCI) can be performed at the same setting of cardiac catheterization and coronary angiogram. Cardiac catheterization can […]
Left Atrial Appendage Occlusion (LAAO)
Atrial fibrillation is the most common heart rhythm disturbance. There are seventy thousand people with AF in the HK. Atrial fibrillation makes your risk of a stroke five times higher. When your heart beats normally, its muscle walls squeeze (contract) to force blood out of the heart and around the body. If you have atrial […]
Atrial Fibrillation (AF) Pulsed Field Ablation (PFA)
Atrial fibrillation is a common heart rhythm disorder in which patients typically experience an irregular, extremely fast heart rhythm. Here there are the three types: Paroxysmal: last for not more than 7 days, usually within 24 hours Persistent: last for longer than 7 days Permanent: last for more than a year It is estimated that […]
Electro-Physiology Study (EPS) & Radio Frequency Ablation (RFA)
Heart rhythm is mainly controlled by the conduction system of the heart. Any abnormality in the conduction system may result in abnormal heart rhythm (arrhythmia). Electro-Physiology Study (EPS) is a test to find out the cause of arrhythmia. A patient suffering from arrhythmia may have palpitation, chest discomfort, dizziness or vertigo. In severe condition, […]
Mitraclip Surgery
The mitral valve is located between your heart’s two left chambers and allows blood to flow forward through your heart during a normal heart- beat. When the mitral valve fails to close completely, blood flows backward in the opposite direction. This backward flow is called mitral regurgitation. Cause: There are several causes of mitral regurgitation. […]
Implantable Loop Recorder (ILR)
Patients may have unexplained recurrent symptoms of dizziness, palpitation or loss of consciousness. There are many causes, such as arrhythmias (abnormal heart rhythm). Sometimes, a definitive diagnosis cannot be made after conventional investigations. Implantable loop recorder (ILR) is used to check whether the symptoms are due to arrhythmias. It is a small device implanted usually […]
Permanent Pacemaker (PPM)
Heart rhythm is mainly controlled by the conduction system of the heart. Any abnormality in the conduction system may result in abnormal heart rhythm (arrhythmia). Arrhythmias with slow heart rate cause dizziness, syncope, heart failure or occasionally cardiac death. Permanent cardiac pacemaker (PPM) is an implantable device used for long-term treatment of arrhythmias with slow […]
Cardiac Resynchronization Therapy (CRT)
Heart failure patients have symptoms of shortness of breath and body swelling caused by decreased pumping of blood from the heart. Initial management includes treating underlying cause, adopting a healthy lifestyle and taking medications. Patients with persistent symptoms despite the above treatments may consider echocardiography. It is essentially an implantable cardiac pacemaker that consists of […]
Implantable Cardioverter Defibrillator (ICD)
Heart rhythm is mainly controlled by the conduction system of the heart. Any abnormality in the conduction system may result in abnormal heart rhythm (arrhythmia). Life-threatening arrhythmias such as ventricular tachycardia (VT) and ventricular fibrillation (VF) cause not only palpitations, dizziness and syncope but also sudden death. Process: You may be discharged from hospital a […]
Atrial Septal Defect Occluded
Atrial septal defect is a common congenital heart disease. Due to the gap between the left and right atrial septum, blood will flow abnormally and increase the burden on the heart. In addition, the foramen ovale is located between the left and right atria. In most people, it will close naturally after birth. If the […]
