There are multiple challenges and unanswered questions encountered by clinicians that evaluate, diagnose and treat patients with suspected or confirmed pulmonary vascular disease (mainly pulmonary hypertension). This course will will provide a deep dive into the diagnosis and therapeutics of pulmonary hypertension supported by the literature and balanced with personal clinical experience. We havecreated this course specifically to address issues where uncertainty and/or controversy exists as well as highlight emerging areas that are just being incorporated into clinical practice. We seek to address the diagnostic and treatment dilemmas posed by these various clinical entities through literature review, sharing of expert opinion, and review of recent guidelines and their applicability to the multiple different nuanced presentations of pulmonary hypertension.
