Abstract
Pulmonary chronic heart (CPC) is an enlargement associated or not with dilation of the right ventricle. Objective: To recall the echocardiographic-Doppler aspects essential for the screening of pulmonary chronic heart. Patients and method: Retrospective study carried out between January 2009 and April 2019 interesting the cases of pulmonary chronic heart. Results: out of 124 cases of pulmonary chronic heart, 11 cases were included. These were four men and 7 women with a mean age of 63 ± 19 years (range: 20-84 years). The radiological and electrical semiology of pulmonary chronic heart was found, lacking specificity and sensitivity. Dilation of the right heart chambers, dyskinesia of the interventricular septum and hypertrophy of the free wall of the right ventricle ˃ 5 mm were observed. The mean maximum velocity of tricuspid insufficiency on continuous Doppler was 4.6 ± 1.32 ms / s (Extremes: 3.59-7.58 m / s) and the mean dilation of the inferior vena cava was 23.2 ± 3.9mm (Extreme: 21.2-27mm). Conclusion: CPC is uncommon and predominant in women. The EKG and chest X-ray are first-line exams without sensitivity or specificity. Screening for CPC is based on echocardiographic-Doppler criteria. The right cardiac catheterization remains the key examination.
Highlights
Chronic cor pulmonale (CPC) is the set of structural modifications of the heart characterized by right cardiac hypertrophy, with or without dilation, relating to an increase in resistance in the small circulation of pulmonary origin, and unrelated to heart disease. left ventricular.The right ventricle (RV) and pulmonary vasculature are accessible on echocardiography
The most illustrative changes affecting this low-pressure vascular system are observed in adults with pulmonary arterial hypertension (PAH)
In subSaharan Africa, CPC is poorly observed in cardiology, unlike pneumology because of its attachment to chronic obstructive pulmonary disease (COPD) and other pulmonary diseases, in particular sleep apnea syndromes, and mixed syndromes [4,5]

In subSaharan Africa, CPC is poorly observed in cardiology, unlike pneumology because of its attachment to chronic obstructive pulmonary disease (COPD) and other pulmonary diseases, in particular sleep apnea syndromes, and mixed syndromes ( obstructive and restrictive) [4,5]
