CTEPH - Chronic Thromboembolic Pulmonary Hypertension Thoughts on Diagnosis and Treatment

Описание: Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is caused by blood clots in the lung arteries and may be a common cause of pulmonary hypertension that can in turn cause heart failure. However, due to its nonspecific symptoms and the fact that such symptoms often don’t appear until 3-6 months after an acute event – if ever – CTEPH often goes undiagnosed. In this discussion, we explore the challenges of diagnosis, the elements of a thorough workup, and potential treatments including surgical pulmonary thromboendarterectomy (PTE). In this discussion, we highlight:

● Why non-specific symptoms including fatigue and shortness of breath often lead practitioners to incorrectly suspect Chronic Obstructive Pulmonary Disease (COPD), when these symptoms in patients with a history of pulmonary emboli may actually indicate CTEPH.
● How to correctly evaluate patients for CTEPH through echocardiograms, V/Q scans, CT scans, pulmonary angiographs and right heart catheterization.
● Why it is important to refer likely patients to a pulmonologist or cardiologist with specific experience in CTEPH, and to surgical centers with the necessary expertise to treat it.
● Video of a successful Pulmonary Thromboendarterectomy (PTE), in which surgeons surgically remove scar tissue and any residual blood clots from the patient's pulmonary arteries – a procedure that can cure the patient of Pulmonary Hypertension.
