Carcinoid heart disease is a cardiac manifestation of carcinoid syndrome, primarily affecting the right side of the heart due to serotonin-induced fibrosis of heart valves. This condition often leads to tricuspid regurgitation and pulmonary stenosis, necessitating early diagnosis and management to prevent severe cardiac complications.

Carcinoid Heart Disease

Cardiac manifestation

Carcinoid syndrome is a group of symptoms caused by the release of serotonin and other chemicals into the bloodstream from a carcinoid tumor, typically originating in the gastrointestinal tract or lungs. It is characterized by flushing, diarrhea, and heart valve lesions, and requires both symptom management and treatment of the underlying tumor.

Serotonin-induced fibrosis

Heart valves are critical structures that regulate blood flow through the heart's chambers, ensuring unidirectional movement and preventing backflow. There are four main valves: the tricuspid, pulmonary, mitral, and aortic valves, each with unique anatomical features and functions that maintain efficient cardiac circulation.

Heart Valves

Tricuspid regurgitation is a condition where the tricuspid valve fails to close properly, causing blood to flow backward into the right atrium during systole, often leading to right-sided heart failure and systemic venous congestion. It can be caused by various factors, including rheumatic heart disease, infective endocarditis, or pulmonary hypertension, and its management depends on the underlying cause and severity.

Tricuspid Regurgitation

Pulmonary stenosis is a condition characterized by the narrowing of the pulmonary valve or artery, which obstructs blood flow from the right ventricle to the lungs. This can lead to increased right ventricular pressure and potentially result in right ventricular hypertrophy if left untreated.

Pulmonary Stenosis

Early diagnosis involves identifying a disease or condition at an initial stage, which can significantly improve treatment outcomes and survival rates. It relies on timely screening, awareness, and access to healthcare services to detect health issues before they progress to more severe stages.

Early Diagnosis

Management is the process of planning, organizing, leading, and controlling resources to achieve organizational goals efficiently and effectively. It involves coordinating human, financial, and physical resources to optimize productivity and foster a positive work environment.
