Aortic Valve * Chordae Tendineae and Papillary Muscles work together to prevent valve leaflets from turning inside out. * Normally‚ the cavity between the pericardial layers contains 10-30mL of serous fluid * A pericardial effusion occurs if additional blood or fluid collects in this space. If the amount of fluid continues to increased and cardiac chamber filling is impeded‚ cardiac tamponade results * VAGUS – major PNS innervation of the heart * CALCIUM – is the main cation affecting

CARDIAC TUMORS INTRODUCTION Cardiac tumours occur quite rarely‚ with metastatic neoplasms three times more prevalent than primary tumours. A large variety of benign and malignant tumours of the heart have been described. These tumors are found mainly in the heart‚ but can occur in the pericardium or the great arteries. Secondary cardiac involvement from malignant tumors of adjacent organs (lung‚ thymus) or from kidney (Wilms tumor) or liver‚ or even remote organs‚ are also seen. ANATOMY AND PHYSIOLOGY

Cardiac Surgeon Cardiac surgeons treat valvular heart diseases such as valve stenosis or vessel insufficiency‚ ischemic heart disease‚ coronary artery disease‚ atherosclerosis and congenital defects. They treat these diseases by repairing or replacing heart valves‚ widen clogged arteries‚ repair aortic aneurysms‚ implant defibrillators and pacemakers‚ and perform double‚ triple‚ quadruple‚ and sometimes even quintuple heart bypasses. Cardiac surgeons must complete internships and residency requirements

Sudden cardiac death happens more these days. There are so many people alone in the United States who just stops breathing with no heart disease involved. So why did their heart stop? There are so many researchers out there trying to figure out the underlying cause of these people who this happen to. There can be other reason why a person’s heart can stop without having a cardiac disease. A person’s body may store minerals that control the arrhythmia of the heart to act a different way.

Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles

Cardiac catheterization is often referred to as coronary angiography or a coronary angiogram. It is a radiographic procedure that is used to look at and visualize the heart and the coronary arteries. During a cardiac catheterization it is possible for the cardiologist performing the procedure to see how effectively blood is flowing through the coronary arteries. In addition‚ this procedure allows the cardiologists to see how blood is moving through the chambers of the heart and how effective the
