Right-sided infective endocarditis is due to intravenous drug abuse. Right-sided infective endocarditis is rare. It comprises 5–10% of infective endocarditis cases. Traditionally, it has been reported more commonly in patients with medical devices such as pacemakers and defibrillators and dialysis catheters. Recently, there has been increase in right-sided infective endocarditis related to intravenous drug abuse. Right-sided infective endocarditis related to drug abuse mostly affects the tricuspid valve and rarely the pulmonary valve. Although, most uncomplicated cases do well with medical treatment, it is associated with considerable morbidity and mortality due to recurrent infection. Surgery for right-sided infective endocarditis is uncommon especially in resource limited setting. Few current studies have explored surgical options in this group of patients. This chapter will review current literature related to right-sided infective endocarditis due to intravenous drug abuse.

Mitral regurgitation is one of the most commonly encountered valvular heart diseases in both the developing and the developed world. From various studies, it is known that chronic mitral regurgitation is associated with progressive left ventricular dysfunction, and eventually death if left untreated. This disease has a long silent period before symptoms manifest. During this latent period, left ventricular function progressively deteriorates and results in poor outcomes for patients even if surgery is performed. A few studies have evaluated the role of medical therapy in patients with chronic mitral regurgitation. This chapter will provide an overview of the use of medical therapy in chronic mitral regurgitation.
