Heart failure: when form fails to follow function

Cardiac performance is normally determined by architectural, cellular, and molecular structures that determine the heart’s form, and by physiological and biochemical mechanisms that regulate the function of these structures. Impaired adaptation of form to function in failing hearts contributes to tw ...

Cardiothoracic surgery
Cardiothoracic surgery is the field of medicine involved in surgical treatment of diseases affecting organs inside the thorax (the chest)—generally treatment of conditions of the heart (heart disease) and lungs (lung disease). Cardiac surgery (involving the heart and great vessels) and thoracic surgery (involving the lungs) are separate surgical specialties, except in the USA, Australia, New Zealand and in some EU countries, such as the UK and Portugal.
