Cardiology
The Thallium Test, also known as a Nuclear Stress Test, assesses heart blood flow under stress and rest conditions. -br A small amount of radioactive tracer (thallium or technetium) is injected into the bloodstream. -br A gamma camera captures images to identify areas of reduced perfusion, helping diagnose coronary artery disease early and accurately.
Cardiology
Enhanced External Counterpulsation (EECP) is a non-surgical treatment that helps improve blood circulation to the heart. -br It involves wearing cuffs on the legs that inflate and deflate in sync with the heartbeat. -br This process boosts oxygen supply to the heart, reduces chest pain, and enhances exercise tolerance, especially in patients with chronic angina or heart failure.
Cardiology
Holter Monitoring is a non-invasive ambulatory ECG test that records the heart’s electrical activity continuously for 24 hours (or longer) while the patient goes about normal activities. -br It detects episodic arrhythmias, pauses, or transient ischemic changes that a standard ECG might miss, helping clinicians tailor therapy accurately.
Cardiology
The HeartWare Ventricular Assist Device (HVAD) is a compact, implantable mechanical pump that helps the heart circulate blood in patients with severe heart failure. -br It supports the left ventricle, easing symptoms and improving organ function. -br HVAD may serve as a bridge to transplant or as long-term support for patients ineligible for heart transplantation.
Cardiology
Cardiac Resynchronization Therapy (CRT-D) combines a pacemaker and defibrillator to regulate the heartbeat. -br It coordinates the heart’s chambers, improving blood flow and preventing sudden cardiac arrest in patients with advanced heart failure.
Cardiology
Fetal Echo (fetal echocardiography) is a specialized ultrasound exam that provides a high-resolution assessment of a fetus’s heart anatomy and function. -br It identifies structural or rhythm abnormalities before birth so parents and clinicians can plan delivery, postnatal care, or in-utero interventions where appropriate. -br Early detection improves outcomes by coordinating neonatal cardiac teams and timely therapy.
Cardiology
Hypoplastic Left Heart Syndrome (HLHS) is a critical congenital heart defect in which the left ventricle, mitral valve, and aorta are underdeveloped. -br The condition prevents effective systemic blood flow, requiring urgent intervention after birth. -br Modern staged surgical approaches — Norwood, Glenn, and Fontan — have transformed outcomes, allowing survival into adulthood with lifelong care.
Cardiology
Percutaneous Transvenous Mitral Commissurotomy (PTMC) is a catheter-based procedure used to treat mitral valve stenosis. -br By inserting a balloon catheter through a vein and inflating it within the mitral valve, the narrowed valve is widened, improving blood flow from the left atrium to the left ventricle. -br It’s an effective option for patients who may not need open-heart surgery.
Cardiology
Radiofrequency Ablation is a widely used technique to treat irregular heartbeats. -br By delivering radio waves through a catheter, it gently removes the tissue causing rhythm disturbance. -br The goal is to help the heart beat normally without lifelong medication.
Cardiology
An Intracardiac Electrophysiology Study (EPS) is a specialized test that maps the heart’s electrical activity. -br It helps identify the source of abnormal heart rhythms (arrhythmias) and determine the best treatment — medication, ablation, or pacemaker implantation. -br The test involves inserting thin catheters through a vein into the heart for precise electrical measurement.
