Types of Ablation & its work

Cardiac ablation is a procedure that can correct heart rhythm problems. Ablation is a procedure used to treat an irregular heart rhythm is called arrhythmia that starts in the heart's upper chambers.  Cardiac ablation can also treat atrial fibrillation, a type of irregular heartbeat. If this is the case, your doctor might call it atrial fibrillation ablation. During the procedure, small wires called electrodes are placed inside your heart to measure your heart's electrical activity. When the source of the problem is found, the tissue causing the problem is destroyed.


How Ablation is work

Each beat of your heart is triggered by an electrical impulse normally generated from special cells in the upper right chamber of your heart. The most common problems result from the use of the catheters long, thin tubes doctors insert into your arteries or veins.

Inserting the tubes can occasionally damage your blood vessel or cause bleeding or infection. These problems are rare. The result is scar tissue that stops the firing pathway of the faulty signals. This technique takes less time than heat ablation and may have similar risks and complications.

Types of Cardiac Ablation

There are have some different types of cardiac ablation. They are;

·        Atrial flutter ablation

·        Pulmonary vein isolation

·        SVT ablation

·        Ventricular tachycardia ablation

Atrial flutter ablation

Atrial flutter ablation is a procedure to create scar tissue within the right upper chamber of the heart in order to block the electrical signals that cause a fluttering heartbeat, which is works scarring or destroying tissue in your heart to disrupt faulty electrical signals causing the arrhythmia.

Atrial flutter ablation can be utilized as an initial rhythm control strategy instead of antiarrhythmic drugs since this procedure is low risk with a high success rate, unlike that of atrial fibrillation where success rates vary and there is a higher complication risk.

Pulmonary vein isolation

Pulmonary vein isolation is a type of cardiac ablation. Cardiac ablation works by scarring or destroying tissue in your heart that triggers an abnormal heart rhythm. Atrial fibrillation is an abnormal heart rhythm that originates in the top chambers of the heart.

In many patients with atrial fibrillation, the left atrium is stretched, which distorts the electrical connections between the heart and the pulmonary veins. Pulmonary vein isolation is used to reduce signs and symptoms and improve quality of life for people living with atrial fibrillation.

SVT ablation

Catheter ablation is a procedure that uses radiofrequency energy to destroy a small area of heart tissue that is causing rapid and irregular heartbeats. To uses a narrow plastic tube, or catheter, to kill cells responsible for the heart rhythm problems caused by supraventricular tachycardia. SVT ablation may restore a normal heart rhythm, which may reduce your symptoms and improve your quality of life.


Ventricular tachycardia ablation

Ventricular tachycardia is an abnormal rapid heart rhythm originating from the lower pumping chambers of the heart. It is a procedure to eliminate the areas of the heart where erratic electrical signals arise that can cause your heart to beat ineffectively. Implantable cardioverter-defibrillators provide mortality benefit and are therefore indicated for secondary prevention in patients with sustained VT, but they do not reduce arrhythmia burden.

Best Clinic to get Coronary Artery Disease Treatment in Waco, TX

What is coronary artery disease? Coronary artery disease (CAD) is a condition in which plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque can harden or rupture, leading to a heart attack or stroke. CAD is a common type of heart disease. It is the leading cause of death in the United States for both men and women. CAD can cause angina (chest pain) or a heart attack. A heart attack happens when plaque ruptures and a blood clot forms in the artery, blocking blood flow to the heart muscle. What are the symptoms of coronary artery disease? Coronary artery disease (CAD) is a condition in which the arteries that supply blood to the heart become narrowed and hardened. This can lead to chest pain (angina), shortness of breath, heart attacks, and even death. CAD is a major cause of death in both men and women in the United
