A 53 years old female with root aortic aneurysm, mitral and aortic valve regurgitation, and multiple bullae of lung. She had history of spontaneous pneumothorax 2 years ago. There was no history of smoking. ANA test and anti ds-dna test were negative. We haven't explore for skeletal and ophthalmic disorders yet, but the patient didn't have any complaint about these organs. What is the possible etiology of these disorders? Are they related to connective tissue disease?
