Ventricular Reduction
Ventriculectomy, or ventricular reduction, is a type of operation in cardiac surgery to reduce enlargement of the heart from cardiomyopathy Cardiomyopathy is a group of primary diseases of the heart muscle. Early on there may be few or no symptoms. As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. A ... or ischemic aneurysm formation. In these procedures, part of the ventricular wall is resected. A Batista procedure is a partial left ventriculectomy that is used to treat advanced heart failure. This procedure is not widely used because outcomes are often unsatisfactory.

Heart
The heart is a muscular Organ (biology), organ found in humans and other animals. This organ pumps blood through the blood vessels. The heart and blood vessels together make the circulatory system. The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the thorax, chest, called the mediastinum. In humans, the heart is divided into four chambers: upper left and right Atrium (heart), atria and lower left and right Ventricle (heart), ventricles. Commonly, the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. In a healthy heart, blood flows one way through the heart due to heart valves, which prevent cardiac regurgitation, backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiomyopathy
Cardiomyopathy is a group of primary diseases of the heart muscle. Early on there may be few or no symptoms. As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. An irregular heart beat and fainting may occur. Those affected are at an increased risk of sudden cardiac death. As of 2013, cardiomyopathies are defined as "disorders characterized by morphologically and functionally abnormal myocardium in the absence of any other disease that is sufficient, by itself, to cause the observed phenotype." Types of cardiomyopathy include hypertrophic cardiomyopathy, dilated cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic right ventricular dysplasia, and Takotsubo cardiomyopathy (broken heart syndrome). In hypertrophic cardiomyopathy the heart muscle enlarges and thickens. In dilated cardiomyopathy the ventricles enlarge and weaken. In restrictive cardiomyopathy the ventricle stiffens. In ...

Ventricle (heart)
A ventricle is one of two large chambers located toward the bottom of the heart that collect and expel blood towards the peripheral beds within the body and lungs. The blood pumped by a ventricle is supplied by an atrium, an adjacent chamber in the upper heart that is smaller than a ventricle. Interventricular means between the ventricles (for example the interventricular septum), while intraventricular means within one ventricle (for example an intraventricular block). In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta. Structure Ventricles have thicker walls than atria and generate higher blood pressures. The physiological load on the ventricles requiring pumping of blood throughout the body and lungs is much greater than the pressure generated by ...

Batista Procedure
The Batista procedure (also called a reduction left ventriculoplasty) was an experimental heart procedure that proposed the reversal of the effects of remodeling in cases of end-stage dilated cardiomyopathy refractory to conventional medical therapy. The hypothesis of the operation appears to be that reduction (resection) of marginally viable ventricular mass may result in superior geometric remodeling thus conferring better performance when faced with ventricular failure. In spite of promising initial results, the method was soon found to be of little if any benefit, and it is no longer considered a recommended treatment for the disease. The Batista procedure was invented by Brazilian physician and cardiac surgeon Randas Batista in 1994 for use in patients with non-ischemic dilated cardiomyopathy. Many of his patients were victims of Chagas disease. Chagas disease represents a parasitic nonischemic cardiomyopathy targeting parasympathetic inflow to the heart. Chagas cardiomyopathy ...

Dor Procedure
The Dor procedure is a medical technique used as part of heart surgery and originally introduced by the French cardiac surgeon Vincent Dor (b.1932). It is also known as endoventricular circular patch plasty (EVCPP). In 1985, Dor introduced EVCPP as a viable method for restoring a dilated left ventricle (LV) to its normal, elliptical geometry. The Dor procedure uses a circular suture and a Dacron patch to correct LV aneurysms and exclude scarred parts of the septum and ventricular wall and would prove to be the best option amongst the other methods of ventricular remodeling, i.e. Cooley’s linear suturing and Jatene’s circular external suturing. EVCPP is a relatively easy procedure that covers all aspects of successful heart restoration—restores ventricular shape, increases ejection fraction, decreases the left ventricular end systolic volume index (LVESVI), and allows for complete coronary revascularization. Cardiac geometry The myocardium consists of a single, vascular, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
