Carcinoid cardiac disease is a common complication of metastatic carcinoid tumours. It is characterized by tricuspid regurgitation and pulmonary stenosis. A 68 years old woman with a metastatic carcinoid tumour was admitted to hospital for congestive cardiac failure secondary to severe tricuspid regurgitation. ⋯ Postoperative echocardiography showed a significant improvement in right ventricular function. Surgical management of carcinoid valvular heart disease of NYHA Stage III patients is associated with an improved 2 years survival (from 8 to 40%) despite a high operative mortality (about 27%). Cardiac surgery remains the only hope of long-term survival with a spectacular improvement in symptoms.

The epidemiology of paroxysmal atrial fibrillation (PAF) is poorly known because of the difficulties in setting up trials to study this condition. Its biannual incidence is about 2 per thousand. Its prevalence is 1 to 2% in a population of over 65 years of age. ⋯ Isolated paroxysmal atrial fibrillation progresses to permanent atrial fibrillation in about 20% of cases, usually if there is underlying cardiac disease. Rheumatic valve disease, cardiac failure, hypertension, previous myocardial infarction and cerebrovascular accidents are often associated with paroxysmal atrial fibrillation. Embolic complications are rare if paroxysmal atrial fibrillation is isolated.
