Ablation Treatment For Atrial Fibrillation

Atrial Fibrillation is a peculiar condition affecting the heart, characterized by rapid and irregular heartbeats. These are commonly referred to as arrhythmias and Atrial Fibrillation is the most common type of arrhythmia. The discovery of a safe and effective treatment for eliminating Atrial Fibrillation remained much of a challenge for doctors worldwide. There are many treatment options available for the treatment of atrial fibrillation, but in many patients who do not tolerate AF after trying the various options available, a new method of treatment is required. It is in such a scenario that Ablation treatment for Atrial Fibrillation came as...

What Is Atrioventricular Canal Defect?

Atrioventricular canal (AV canal) defect is a problem that exists from birth in which there appears some abnormalities in the heart. There develops a hole between the chambers of the heart and an impairment of the valves that regulate the blood flow in the heart, even during the first weeks of pregnancy. Triscupid and mitral valves, the two valves that separate the upper and lower chambers of the heart form as one big valve that crosses the hole (the defect). The defect is also known as endocardial cushion defect and antrioventricular septal defect. In the normal scenario, the right chamber...

What Are Drug-Eluting Stents?

A drug-eluting stent is a type of stent applied in the case of  diseased or narrowed coronary arteries, gradually releasing a drug to block any cell proliferation that occurs due to the healing tissues around the stent. Usually restenosis occurs even after the artery is repaired, which is the renarrowing of the artery caused due to tissue overgrowth around the stent. The renarrowing again leads to constricted blood flow proving fatal unless countered. In this visual illustration, a bare-metal stent is inserted at first but the artery re-narrowing occurs. During the second trial, a drug-eluting stent is used which successfully...

What Is Minimal Invasive Mitral Valve Surgery?

Let us have a brief discussion on the procedure of minimal invasive mitral valve surgery. Firstly the patient’s cardiac monitoring is taken note of and then general anesthesia is given. The surgeon uses a sternotomy to access the heart. Then the bypass is instituted. A cross clamp is then applied to the aorta to stop the flow of blood. Then an opening is made in the heart by the surgeon in order to look into the mitral valve.  There are two ways to visualize the mitral valve. That is either through the left atrium or by opening the right atrium.With...

What Is Endoscopic Vein Harvesting?

Endoscopic Vein Harvesting (EVH) is a procedure wherein the vein is removed safely and in a less invasive fashion. This procedure uses a small video camera and endoscopes in order to keep a track of the removal of the vein harvest. The main surgical procedure for carrying on a bypass surgery involves the usage of the healthy blood vessel to bypass a damaged artery. Now let us now know a little more about the vein harvesting. There are two main types of the vein harvesting, that is the traditional vein harvesting and the endoscopic vein harvesting. Let us have a...

What Is Percutaneous Coronary Intervention?

Percutaneous coronary intervention is an interventional procedure, used to open up narrowed segments of coronary arteries in cases of Coronary artery disease (CAD). These segments are stenosed due to the accumulation of cholesterol laden plaques, resulting in atherosclerosis. Percutaneous coronary intervention can be performed to reduce or eliminate the symptoms of coronary artery disease (CAD), including chest pain, shortness of breath on exertion, and heart failure. PCI is also used to abort an acute myocardial infarction (Heart attack). PCI is less invasive than coronary artery bypass surgery (CABG). PCI is used for different procedures such as balloon angioplasty, implantation of...

Genetic Disorders Can Be The Culprits Of Unexpected Cardiac Deaths

Scientists have come to the conclusion that sudden deaths due to cardiac issues can be caused by genetic defects. This fact can be of immense help in trying to reduce sudden deaths in patients who have been suffering from Long QT syndrome which is an unusual and hereditary heart rhythm disorder.  Further these studies state that particular genetic mutations cause defects that can be the reason for sudden death and other cardiac ailments in the patient. These findings are particularly true of have this condition but do not exhibit any clinical symptoms and this constitutes for about 70% of the...

Blood Oxygen Test Can Help Detect Congenital Heart Defects In Newborns

When we talk of congenital anomalies and birth defects, heart malformation are the most common amongst them and account to almost one of every 100 births globally. Of these, almost 25% of them are fatal. Many a times paediatricians fail to recognize and miss out on diagnosing these defects, as the new born heart and lungs function normally and continue to mature for a few initial days.    Dr Alan R. Fleischman, MD, who is the medical director of the March of Dimes in N.Y, says that it is difficult to diagnose a heart defect in many cases. Many a...

What Is Scimitar Syndrome And What Are Its Complications?

Scimitar syndrome is also called as pulmonary venolobar syndrome. It is a rare condition with congenital etiology. This congenital cardiac disorder has an anomalous venous return from the right pulmonary, which is more often partial.   In a normal pulmonary venous circulation the oxygenated blood is exchanged from the capillaries to the left side of the heart.In the Scimitar syndrome, the anomalous vein shunts the blood to the inferior vena cava, which in an x-ray resembles a scimitar shape.Scimitar syndrome is associated with hypoplasia of the right lung, hypoplasia of the pulmonary artery and pulmonary sequestration (or a cystic lung...

Open Heart Surgery Successfully Completed in The Smallest Baby

Elena, a premature baby who came out six weeks earlier had to undergo an open heart surgery in Birmingham Children’s Hospital that saved her life. She was diagnosed with an extremely uncommon heart condition much before she was born during her twentieth week scan. The scan revealed a missing pulmonary valve, a big hole between her two ventricles and enlarged pulmonary arteries.  She was born normally but six weeks early on January 13th at University Hospital Coventry and Warwickshire and found to have breathing difficulties. The baby was transferred to Birmingham Children’s Hospital where the reputed cardiac surgeon, Mr., William...
