Admin — Sat, 16 Jul 2011 13:42:18 +0000

Kawasaki disease is an Idiopathic multisystem disease characterized by vasculitis of small & medium blood vessels, including coronary arteries. This video includes everything from history of the disease to treatment plans and options.

Closed Heart Surgery

Closed heart surgery implies that the “heart lung machine” or “bypass” machine is not used and the heart is visualized but not cut open. Listed below are details of three types of closed heart surgery:

Open Heart Surgery

maitri — Wed, 19 Jan 2011 08:28:25 +0000

Open heart surgery is any surgery where the chest is opened and surgery is performed on the heart muscle, valves, arteries, or other heart structures (such as the aorta). The term “open” means that the chest is “cut” open .

Most heart surgery is performed under general anesthesia, requiring that the patient be intubated and put on a ventilator(artificial breathing machine). Some less invasive procedures, such as placing stents or a pacemaker, may be performed with monitored anesthesia care, known as twilight sleep.

Cardiac Surgery in Children- A Detailed Glossary

maitri — Wed, 19 Jan 2011 08:27:43 +0000

Type	Procedure	Defects Treated	Description
Shunts	Blalock-Taussig	Reduced pulmonary blood flow (TOF, TGA, pulmonary atresia, tricuspid atresia)	Classic: Anastomosis of subclavian artery to PA (with or without modification)
Atrial mixing	Surgical atrial septostomy	TGA (early palliation), mitral atresia, complex congenital heart disease	Also called Blalock-Hanlon procedure
	Balloon atrial septostomy	TGA, tricuspid atresia	Percutaneous atrial septostomy, also called Rashkind balloon procedure
Closures	Atrial septal defect (ASD) closure	ASD with significant shunt	Primary or patch closure
Closures	Atrial septal defect (ASD) closure	ASD with significant shunt	Percutaneous closure
	Ventricular septal defect (VSD) closure	Isolated VSD or with other anomalies (TOF)	Primary or patch closure
	Patent ductus arteriosus (PDA) ligation	Patent ductus arteriosus	Ligation ± division of PDA
	Patent ductus arteriosus (PDA) ligation	Patent ductus arteriosus	Transcatheter technique
	Endocardial cushion defect repair	Endocardial cushion defect (also called atrioventricular canal defect)	Closure of ASD and VSD, repair of atrioventricular valve abnormalities (e.g., cleft mitral leaflet)
PA banding	Surgical reduction in flow area of PA	Large left-to-right shunt lesions	PA band to decrease PA flow and pressure
Atrial baffles	Mustard	TGA (replaced by arterial switch procedures at many centers)	Dacron or pericardial baffle directs systemic venous return to PA via anatomic LV, pulmonary venous return to aorta via anatomic RV
	Senning	TGA (replaced by arterial switch procedures at many centers). May be used as part of “double switch” procedure for L-TGA	RA free wall and interatrial septal tissue used for interatrial baffle similar to a Mustard repair.
Relief of stenosis	Aortic coarctation repair	Aortic coarctation	Various procedures including end-to-end anastomosis, patch enlargement, Gore-Tex graft; balloon dilation for recoarctation
Relief of stenosis	Aortic coarctation repair	Aortic coarctation
	Pulmonic valvotomy	TOF, pulmonic stenosis	Brock trans-RV approach
			Direct surgical repair
			Balloon dilation
	Aortic valvotomy	Congenital aortic stenosis	Direct surgical valvotomy or percutaneous balloon dilation
	Mitral repair	Congenital mitral stenosis	Surgical commissurotomy—initially a “closed” procedure without cardiopulmonary
	Mitral repair	Congenital mitral stenosis

WHAT IS CARDIAC SURGERY?

maitri — Wed, 19 Jan 2011 08:26:44 +0000

Cardiac surgery is a surgery on the heart and/or great vessels performed by a cardiac surgeon. Heart surgery is done for a variety of reasons and ranges from minimally invasive procedures to actually removing the heart and replacing it with a donor heart. Frequently, it is done to treat complications of heart.

KNOW ABOUT YOUR HEART

maitri — Wed, 19 Jan 2011 08:26:09 +0000

The heart is an organ which pumps blood to various parts of the body. The human heart consists of four chambers: right and left atria and right and left ventricles. The two atria act as collecting reservoirs for blood returning to the heart while the two ventricles act as pumps to eject the blood to the body. As in any pumping system, the heart comes complete with valves to prevent the back flow of blood. Deoxygenated blood returns to the heart via the major veins (superior and inferior vena cava), enters the right atrium, passes into the right ventricle, and from there is ejected to the pulmonary artery on the way to the lungs. Oxygenated blood returning from the lungs enters the left atrium via the pulmonary veins, passes into the left ventricle, and is then ejected to the aorta.

Pediatric and Fetal Echo Z-Score Calculators

Admin — Fri, 07 Jan 2011 17:36:33 +0000

The free Pediatric and Foetal echo Z score calculators allow you to generate z-scores and reference values (normal values) for Pediatric and Foetal echo using data compiled from medical literature and publications

Click to select the Calculator you want to use

Aortic Root Z-Scores

Calculate BSA-adjusted z-scores of the aortic annulus and sinuses of Valsalva using data published by Boston Children’s Hospital. (Updated 11/2008: added percentiles)

Ascending Aorta Z-Scores

Z-Scores of the ascending aorta (AAO) and aortic root. Data from the Children’s Heart Center, Halifax, Nova Scotia, published in 2006 and from Hôpital Bichat, Paris, France published in 2010

Cardiac Valve Z-Scores

Calculate BSA-adjusted z-scores of the mitral valve, tricuspid valve, aortic valve, and pulmonary valve using data published by Cincinnati Children’s Hospital. This data is also used to create dynamic z-score tables.

Coronary Artery Z-Scores

Calculate BSA-adjusted z-scores of the proximal coronary arteries (for patients with Kawasaki disease) using data published by Boston Children’s Hospital and Children’s National Medical Center, Washington, DC and Montreal, Canada (also calculates aortic valve standardized coronary z-scores).

Fetal Echo Z-Scores

Calculate gestational age-adjusted z-scores for fetal echo (left ventricle, mitral valve, aortic valve, aortic arch, etc.) using data published by The Royal Brompton Hospital and Boston Children’s Hospital.

LV Mass Z-Scores

Calculate height-adjusted z-scores of left ventricular mass (m-mode derived calculation) using data published by Montreal Children’s Hospital.

M-Mode Z-Scores

Calculate BSA-adjusted z-scores for common M-Mode measurements (LVEDD, LVESD, IVS, LVPW, LA) using data published by Johannes Gutenberg University, Germany.

TAPSE

Reference values for right ventricular systolic function, using tricuspid annular plane systolic excursion (TAPSE).

Z-Scores of Cardiac Structures: Detroit Data

Calculate BSA-adjusted z-scores of 21 common pediatric echo measurements (m-mode, mitral valve, aortic valve, pulmonary arteries, etc.) using data published by Detroit Children’s Hospital. (Updated 11/2008: added percentiles)

Z-Scores of Cardiac Structures: Wessex Data

Calculate BSA-adjusted z-scores of 15 cardiac structures (mitral valve, aortic valve, pulmonary arteries, etc.) using data published by the Wessex Cardiothoracic Unit, Southampton UK.

TAPSE Z-Scores

Admin — Thu, 06 Jan 2011 20:46:55 +0000

Use this free TAPSE Z scores calculator to obtain reference values for right ventricular systolic function using the tricuspid annular plane systolic excursion (TAPSE) measurements. Data are from 640 patients, aged 1 day to 18 years, as described by investigators in Graz, Austria. TAPSE was measured by “2-dimensional echocardiography–guided M-mode recordings from the apical 4-chamber view, with the cursor placed at the free wall of the tricuspid annulus.”
