Echocardiography in sarcoidosis

Area of Science:

• Cardiology
• Pulmonology
• Medical Imaging

Background:

• Sarcoidosis is a multisystem inflammatory disease that can affect the heart.
• Cardiac involvement in sarcoidosis can lead to various cardiovascular complications.
• Echocardiography is a key non-invasive tool for assessing cardiac structure and function.

Purpose of the Study:

• To evaluate cardiac abnormalities in patients with biopsy-proven lung sarcoidosis using echocardiography.
• To investigate the prevalence of mitral valve prolapse, pericardial effusion, and septal abnormalities.
• To assess the impact of corticosteroid treatment on echocardiographic findings and patient symptoms.

Main Methods:

• A cohort of 39 patients with biopsy-proven lung sarcoidosis underwent comprehensive echocardiographic examinations.
• One-dimensional, two-dimensional, and pulsed Doppler echocardiography were utilized.
• Echocardiographic parameters including mitral valve morphology, pericardial effusion, and interventricular septum function were analyzed.

Main Results:

• Mitral valve prolapse was identified in 18 patients (46.2%), potentially explaining symptoms like palpitations and chest pain.
• A minor pericardial effusion was present in 8 patients (20.5%).
• Reduced systolic thickening and excursions of the interventricular septum were observed in 4 patients (10.2%), possibly due to granulomatous infiltration. Asymmetric septal hypertrophy was also noted in 4 patients (10.2%).
• Corticosteroid therapy did not significantly alter echocardiographic findings or pericardial effusion volume.
• However, corticosteroid treatment led to the disappearance of extrasystoles and subjective relief in patients experiencing palpitations and arrhythmias.

Conclusions:

• Echocardiography is valuable in detecting cardiac abnormalities in lung sarcoidosis patients, notably mitral valve prolapse.
• While corticosteroids may not modify structural cardiac changes, they can alleviate arrhythmic symptoms in sarcoidosis patients.
• Further research is warranted to understand the long-term cardiac implications of sarcoidosis and optimize management strategies.
