We report a case of global heart failure revealing aortic regurgitation in a 50-year-old male with acromegalic dysmorphism. The echocardiography noted a hypertrophy and dilatation of left ventricular and severe aortic regurgitation. A large pituitary adenoma was visualized using magnetic resonance imaging. Growth hormone was high.

  Introduction Top

Acromegaly is a dysmorphic syndrome resulting from inappropriate secretion of growth hormone. Cardiovascular manifestations such as high blood pressure, heart failure, or rhythm disorder are possible.[1],[2] The particularity of this case is the association with aortic valve regurgitation – is that the outcome of acromegaly or a simple coincidence?

  Case Report Top

A 50-year-old male was admitted to the department of cardiology in the teaching hospital of Brazzaville, July 2016, for the management of global heart failure. The family history reported cancer in father and sister. He present acromegalic dysmorphism due to pituitary adenoma, diagnosed in 1994. High blood pressure occurred after ten years. Recurrent dyspnea started three years ago, and hospitalization was required in July 2016 for heart failure. The clinical examination noted a dysmorphic syndrome, obesity, and global heart failure [Figure 1]. The heart rate was 100 beats per minute, and the blood pressure was 180/100 mmHg. A diastolic blowing of aortic regurgitation was perceived with 3/6th of intensity. Chest radiography showed cardiomegaly (cardio-thoracic ratio (CTR) =64%). The electrocardiogram was in sinus rhythm with left atrial and ventricular hypertrophy. Doppler echocardiography showed an ejection fraction at 46%, dilatation of cardiac cavities (left ventricular [LV] =69 mm, right ventricular [RV] =31.8 mm, LA = 37 cm2, and RA = 40 cm2), and concentric LV hypertrophy (septal and parietal thickness at 17.5 mm). The diameter of the aorta was 41 mm, aortic valve seemed normal with anyway a severe regurgitation (Pressure half time [PHT]= 173 ms, regurgitant volume at 69 ml/beat), [Figure 2]. Pulmonary artery systolic pressure was 61 mmHg. Magnetic resonance imaging showed a large pituitary adenoma with suprasellar development, measuring 3 cm × 2.1 cm with a large symmetrical enlargement of the floor of sella turcica [Figure 3]. Biology showed a high level of growth hormone (hGH >150 mIU/l). Thyroid-stimulating hormone, prolactinemia, cortisolemia, and fasting glucose were normal.

Global heart failure and severe aortic regurgitation were retained in a 50-year-old male with a pituitary adenoma responsible of acromegalic dysmorphia.

Daily medical treatment included perindopril 10 mg, furosemide 40 mg, and amlodipine 10 mg. Because pituitary adenoma and dysmorphic syndrome remained stable, cardiac surgery for aortic valve replacement was indicated.

  Discussion Top

Acromegaly is a rare condition.[1],[3] Cardiovascular manifestations which are present in one-third of cases are related to the age at the diagnosis and the duration of the evolution of the disease.[2] It can cause high blood pressure, physical limitation, or heart failure. Rhythm disorders have also been reported.[1],[2] Their mechanisms are crossed: hypertension, hypertrophy, and dilation of the left ventricle.[2],[4] The presence of valvulopathy is poorly reported.[1],[3],[4] However, in Desailloud et al.'s study conducted in France,[2] the relative risk of occurrence of valvulopathy in an acromegalic disease was 19%. Hence, in their study of 40 cases of acromegaly, aortic regurgitation had appeared in 30% of patients.

  Conclusion Top

Cardiac manifestations are possible during acromegaly. The association of valvulopathy is rare, and its mechanism is unclear.
