What is Transcranial Doppler (TCD) Bubble Study? A Transcranial Doppler (TCD) bubble study is a medical diagnostic procedure that uses ultrasound to examine the blood flow in the arteries and veins within the brain. After injecting a small amount of bubbles into a vein in the arm, an ultrasound probe (positioned on the head) utilizes sound waves to detect the presence of these bubbles traversing the brain arteries. Normally, these injected bubbles are trapped within the lung and do not … Continued

Untuk membaca dalam Bahasa Đọc thêm bằng tiếng Việt  The triclip is a percutaneous treatment ( non surgical) for severe tricuspid valve regurgitation (leaking) . The tricuspid valve leaks when the leaflets of the valve are unable to contact or close tightly. This clip works by grasping the leaflets together and tightening the valve thus enabling better closure and reducing the leakage The procedure is done under general anesthesia with transesophageal echocardiographic guidance ( ultrasound) A tube is first placed … Continued

Mitraclip (Device Used To Treat Mitral Valves Regurgitation)

MitraClip is a medical device used to treat a heart condition called mitral regurgitation. It’s a minimally invasive procedure where a small clip is attached to the mitral valve in the heart to help it close properly. This can improve the heart’s function and reduce symptoms like shortness of breath. It’s often used for patients who are not good candidates for traditional open-heart surgery.   How Mitraclip Is Done * Preparation: The patient is usually given anesthesia to make them … Continued

Valve in valve procedure and paravalvular leaks

Valve in valve procedure and paravalvular leaks Bioprosthetic heart valves, despite best attempts at tissue treatment will suffer from degeneration. This can occur due to structural deterioration of the valve leaflets (e.g. calcium accumulation and scar formation leading to immobile and obstructive to the blood flow or perforation and tears leading to severe leakage). Occasionally, deterioration can occur when holes, gaps or slits occur outside the surgical valve due to disruption of previously placed sutures The traditional option was to … Continued

Tricuspid valve regurgitation

The tricuspid valve is a valve located between the right upper and right lower chambers of the heart. This valve controls the flow of blood in a single direction. Tricuspid regurgitation occurs when the valve does not close well. In essence the valve cannot seal tightly enough resulting in a backflow of blood in the opposite direction. This results in a significant amount of blood volume re-entering the right atrium and raises the pressures in the chamber. When this happens … Continued

Right heart catheterization

This is a procedure that is used to assess pressure and oxygen levels in the heart. A very small flexible catheter with a balloon tipped flotation catheter is introduced via the vein the right thigh. This balloon floats and travels with blood flow and together with some control externally would arrive at the various chambers on the heart. This is monitored using X -ray (fluoroscopy). This procedure is indicated for a variety of situations: Studying the function of the heart … Continued

Left atrial appendage closure

The left atrial appendage (LAA) is a structure in the left upper chamber of the heart. When some patients develop atrial fibrillation(AF) (an irregular heart beat), blood flow within the left heart chamber and especially that in the LAA becomes sluggish. This can lead to an increased risk of clot formation within the LAA. Occasionally, these clots can migrate and travel via the bloodstream and lodge themselves into blood vessels causing disastrous consequences. If the blood vessel obstructed is in … Continued

Device closure of Patent Foramen ovale

About a quarter of people have this. The foramen ovale is an important structure during fetal life but mostly closed after birth. When this tissue flap fails to close we call it Patent Foramen Ovale (PFO). This small opening in the heart can, in some cases, allow blood clots to pass from the right to the left side of the heart and then travel via one of the blood vessels to the brain, obstructing this vessel and causing a stroke. … Continued
