Myxoma comprises 30 -40 % of all benign cardiac tumors in adults. And it occur about 0.5 – 1 for each million in a year . Myxoma occur in any chamber of the heart . but have a special predilection for the left atrium. Surgical resection is the only effective therapeutic option for patients with cardiac myxoma . It may be done with any other cardiac surgery ( valve replacement or CABG ) . surgery should not be delayed because death from obstruction to flow within the heart orembolization may occur in as many as 8% of patients awaiting operation . New studies show a good result for the patients who undergo the surgical resection for the myxoma . and low percentage of mortality .

A-60 years old woman, did cardiac consulting for hypertension Interrogation: The patient is asymptomatic she has the following cardiac risk factors Smoking (1) Packet / day for 40 years and arterial hypertension for 20 years ago , uncontrolled she ha s not surgical or medicals antecedents Cardiovascular examination: BP: 14,5\90, pulse : 80\ M, No murmurs no additional voices ,peripheral pulse are palpable, no edema , not congestion jugular . Twelve-lead electrocardiography showed sinus rhythm,there are not troubles of repolarization, no of conduction Chest radiography showed normal cardiac silhouette, blood tests are normals Echocardiography throw chest : showed the presence a mass in the left atrium, measuring 4 x 3.5 cm lobed ,smooth heterogeneous, attached to the atrial septum , it has broad base extends from the fossa ovalis to the roof of the left atrium beside superior vena cava to the right side Echodppler throw esophagi does not appear more data, but it showed absence of anthor tumors in other cardiac cavities Cardiac catheterization: showed the presence of multiple aneurysms on the coronary arteries with stenosis of 50% on the first segment of the anterior descending coronary artery(LAD) The patient has been transferred to the Department of Cardiac Surgery, where the tumor was removed successfully and Histopathology showed that it is an aterial myxoma ( benign tumor)
The efficiency of anti-arrhythmic drugs could be weak if they were administrated in insufficient therapeutic concentrations in target tissues of the cardiac muscle. Anti-arrhythmic drugs concentrations should be high enough to reach the steady- sta te for the chronic arrhythmia patients, this could be fatal due to drug accumulation in the cardiac and body tissues. The most important side effect of all kind of anti-arrhythmic drugs is the capability to initiate different types of cardiac arrhythmia formations in the treated individuals. The aim of this study is to prove the effectiveness of delivering an anti-arrhythmic drug, directly to target tissues of the cardiac muscle by using the Iontophoresis concept, in order to minimize the side effects in cardiac and body tissues and optimize the benefits of anti-arrhythmic drugs in target tissues. The results from series of experimental procedures proved that very-low iontophoretic current's values ranges allow feasible and effective passage of anti-arrhythmic drug's ionized particles into cardiac tissues, and in the same time they were safe on the innervation of autonomic nervous system fibers in the cardiac muscle. This study focused on relationships among the different parameters which control the Iontophoresis procedures.
• Although cardiac injuries are rare but cause high mortality. • Up to 20% of the injured to the hospital alive. • The key to success is early diagnosis and ambulatory surgery. • Echocardiography help early diagnosis of damage • Midline transster nal incision is the choice in patients with a degree of heamodynamic stability. • Anterieur left Thoracic incision is the choice in unstable patients and is often done in the Emergency Department and as part of recovery .
Primary cardiac tumors are considered rarely common tumors. They are classified into two kinds of tumors: (1) Benign cardiac tumors frequently located in the left cardiac chambers, mostly common is the Myxoma , which is treated by complete good ex cising surgery including excision of the tumor base. (2) Malignant primary tumors, which prefer the right cardiac chambers, mostly common are Angiosarcoma and Mesothelioma, whose primary treatment is nearly complete excision surgery with the help of artificial heart and lung, followed by chemotherapy and radiotherapy, which seldom prolong the life of the patient for about three years.
To evaluate the role of Endoscopic Sinus Surgery ( ESS ) in excision of inverted papillomas , and to compare the recurrence rate in this approache with that of external one . Background: Assessment of new surgical technique in the management of the most important benign para-nasal sinuses tumor.
