Heart Failure - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: In the normal heart, deoxygenated blood flows from the body through the superior and inferior vena cava into the right atrium. The blood, a volume known as preload, then moves into the right ventricle, which contracts and sends blood out of the heart and into the lungs to remove carbon dioxide and collect oxygen. Oxygenated blood moves from the lungs into the left atrium, then moves into the left ventricle which contracts and propels oxygenated blood out of the heart and into the systemic circulation against resistance known as after load. When the heart losses its ability to pump enough blood to meet its needs or those of the body, the diagnosis is heart failure. In left-sided heart failure, the left ventricle does not pump an adequate volume of oxygenated blood into the systemic circulation. Left-sided heart failure causes pulmonary congestion, a buildup of blood and fluid in the lung tissues that interferes with respiration. In response to the low levels of oxygen, the heart rate increases to compensate for the left ventricle's weakened state and to meet the body's oxygen demands, which in time leads to thickening, or hypertrophy, of the myocardium as it labors to push blood out of the heart against the increasing pressure in the pulmonary vessels and fluid in the lungs and continuing the cycle of cardiac muscle damage. In right-sided heart failure, the right ventricle is unable to contract with enough force to drive enough blood through the pulmonary arteries to the lungs for oxygenation. Right-sided heart failure results in a buildup of blood in the venous circulation, causing fluid retention called edema throughout the body. Deprived of sufficient blood flow, the kidneys fail to filter excessive sodium and water from the blood, leading to a fluid imbalance and increased vascular resistance against which the heart must pump. The result is perpetual damage to the heart's overworked tissues. Treatment for heart failure involves changes in lifestyle such as diet and exercise, medication, surgery, or a combination of approaches. Commonly, therapies for right-sided heart failure are geared toward improving left sided cardiac function. In heart failure, an increase in fluid volume places added stress on the overloaded heart. Diuretic medications reduce fluid volume and venous return by inhibiting sodium and water reabsorption along the kidney's renal tubular system, increasing the amounts of sodium and water excreted in the urine and the volume of urine produced. ACE inhibitors block hormones in the renin-angiotensin-aldosterone system, dilating vessels, lowering blood volume and venous return, decreasing the heart's workload, and halting ventricular hypertrophy. Digoxin is a medication that increases the force of myocardial contractility by raising intracellular sodium and calcium concentrations. To compensate for the decreased cardiac output in heart failure, the sympathetic nervous system initiates norepinephrine release, raising the overworked heart's rate and force of contractions. Beta-blockers are prescribed to compete with norepinephrine molecules for binding sites on cardiomyocytes, preventing norepinephrine's effects, resulting in reduced speed and strength of the contractions, which can support more efficient circulation through the body.

What attorneys say about MLA and The Doe Report:
"It is with great enthusiasm that I recommend Medical Legal Art. We have used their services for three years and always found their professionalism, quality of work, and timely attention to detail to exceed our expectations. We recently settled two complicated catastrophic injury cases. One medical malpractice case involving a spinal abscess settled for 3.75 million and the other involving injuries related to a motor vehicle accident settled for 6.9 million. We consider the artwork provided by MLA to have been invaluable in helping us to successfully conclude these cases.

I highly recommend MLA to anyone seeking high quality, detailed medical legal artwork."

E. Marcus Davis, Esq.

"Medical illustrations are essential during trial for any medical malpractice case. The people at MLA have the uncanny ability of creating medical illustrations that simplify the most complex of medical concepts and human anatomy to a lay audience. The exhibits of MLA allow experts to easily describe complex concepts and human anatomy in a manner that could not be done otherwise.

In addition, their custom illustrations show in great detail the extent of injuries suffered and the devastating effects they have had on the client's anatomy. These custom illustration can show, side by side, the body before and after a catastrophic injury. The effect of this juxtaposition is unmatched by any testimony that can be adduced at the time of trial.

Even jurors after trial have commented on the ease with which they grasp medical concepts and anatomy once the MLA exhibits were introduced and used by my experts. Even judges who have "seen it all" are thoroughly impressed by the detail and sophistication of the illustrations.

I would not want to try a case without them."

"This past year, your company prepared three medical illustrations for our cases; two in which we received six figure awards; one in which we received a substantial seven figure award. I believe in large part, the amounts obtained were due to the vivid illustrations of my clients' injuries and the impact on the finder of fact."

"[Your staff] was extremely efficient, cooperative and gracious and [their] efforts produced a demonstrative exhibit that we used effectively throughout our trial. The jury verdict of $3,165,000.00 was, in no small measure, due to the impact of the demonstrative evidence. You may be sure that we will call again."
