Abstract:
The most common causes of dyspnea are not neuromuscular but rather are cardiac and pulmonary. However, dyspnea is an important and serious manifestation of many neuromuscular disorders, and it may compound an underlying pulmonary or cardiac problem. The diaphragm is a skeletal muscle under the control ofperipheral nerves(phrenic nerves) and may be targeted by inflammatory neuropathies such as Guillain-Barrésyndrome(GBS), chronic inflammatory demyelinating polyneuropathy(CIDP), and brachial plexitis, myopathies such as acid maltase deficiency and muscular dystrophies, and neuromuscular disorder

Abstract:
Transthoracic and transoesophageal echocardiography represent the first-line diagnostic tools for imaging space-occupying lesions of the heart. Cardiac masses can be classified as tumours, thrombi, vegetations, iatrogenic material, or normal variants. Occasionally, extracardiac masses may compress the heart and create a mass effect. Cardiac masses may be suspected from the clinical presentation. This is the case in patients with an embolic event presumed to be of cardiac origin or in patients with infective endocarditis. Otherwise, a cardiac mass can be identified during the routine investigat

Abstract:
Even if sudden cardiac death is considered to be the most frequent cause of death in adults in industrialized countries, its incidence varies widely, depending on the definition and the source and quality of underlying data. It is estimated that about 70-80% of cases are due to coronary heart disease. The remaining 20% are attributable to a wide variety of inborn, genetically determined or acquired diseases, including a small group with hitherto undefined background. Prevention primarily encompasses the treatment of cardiovascular risk factors to avoid manifestations of coronary heart disease.

Cardiac masses are abnormal structures within or immediately adjacent to the heart. They have to be distinguished from variants of normal cardiac structures, postoperative changes, and ultrasound artefacts. These abnormal masses may be localized in the left or right heart cavities, with different clinical manifestations according to their localization. Among the abnormal cardiac masses (thrombus, vegetations, tumours), tumours are not discussed in this chapter. Echocardiography is the main but not the only imaging technique for the evaluation of cardiac masses, and is largely available. Hence,

Hypomagnesemia is a relatively common electrolyte abnormality that may produce little to no significant clinical manifestations in patients. Commonly used medications such as proton-pump inhibitors and antidepressants can cause magnesium deficiency. The primary cardiac effect of hypomagnesemia is a prolongation of the Q-T interval. It is exposure to other drugs in the perioperative period and physiologic changes caused by anesthesia and surgery that can further alter cardiac electrophysiology and lead to serious ventricular dysrhythmias.

Williams-Beuren syndrome, also known as Williams syndrome (WS) is a genetic disorder involving the elastin gene on chromosome 7q11.23. Elastin is important for elasticity of vascular walls, and its deficiency can lead to widespread arteriopathy, most notably supravalvar aortic stenosis of the ascending aorta and coronary artery stenosis. Because of these cardiac defects, patients with WS are at high risk for cardiac arrest under anesthesia with a documented incidence around 5%.

Abstract:
Heart failure is a clinical syndrome characterized by the inability of the heart to maintain adequate cardiac output to meet the metabolic demands of the body while still maintaining normal or near-normal ventricular filling pressures. Heart failure may be present at rest, but often it is present only during exertion as a result of the dynamic nature of cardiac demands. For correct treatment of heart failure, the mechanism, underlying cause, and any reversible precipitating factors must be identified. Typical manifestations of heart failure are dyspnea and fatigue that limit activity tolerance
