Key result
V/Q scan remains the best screening tool and conventional angiography the gold standard for CTEPH.
Why the study?
CTEPH is underdiagnosed despite being the only potentially curable form of pulmonary hypertension, necessitating a review of diagnostic modalities.
This review highlights the role of echocardiography, ventilation/perfusion scanning, and other modalities in the early diagnosis of CTEPH, which is crucial for potentially curative interventions.
Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by chronic obstruction of major pulmonary arteries by organized thromboembolic material. Untreated CTEPH can result in pulmonary hypertension and eventually right heart failure, yet it is the only form of pulmonary hypertension that is potentially curable with surgical or catheter-based intervention. While early diagnosis is key to increasing the likelihood of successful treatment, CTEPH remains largely underdiagnosed. This article reviews the role of echocardiogram, ventilation/perfusion scan, and other available modalities in the diagnosis of CTEPH.

Memon et al. (2016) conducted a review in Chronic Thromboembolic Pulmonary Hypertension (CTEPH). Diagnostic modalities (V/Q scan, CTPA, Pulmonary Angiography, RHC) was evaluated. Ventilation/perfusion (V/Q) scan remains the best screening tool and conventional pulmonary angiography the gold standard for diagnosing chronic thromboembolic pulmonary hypertension.
