Introduction:

Two-dimensional transthoracic echocardiogram is a portable, non-invasive tool, with greater accessibility than the right heart catheterization and provides multiple reliable parameters regarding pulmonary hemodynamics; however, the available information supporting the use of two-dimensional transthoracic echocardiogram in subjects with suspected HP is very limited.

Material and methods:

This is a cross-sectional analysis of a cohort study that has prospectively and consecutively included all subjects with suspected pulmonary hypertension (different from group 2), which have been evaluated in the Respiratory and Thoracic Surgery Unit of the Hospital Regional de Alta Especialidad de la Península de Yucatán, México.

Results:

The report includes 52 patients with a median age of 52 years (IQR 31-65) and 78% were female. Among the possible cases attributable to group 1, the main subgroup was the one related to congenital heart diseases. Among the echocardiographic variables that may allow better screening of patients with suspected HP group 1 were: TAPSE (OR 0.82, 95% CI 0.69-0.96) and PsAP (OR 1.08, 95% CI 1.04-1.14).

Conclusion:

In our setting, the use of ECOTT is acceptable in the evaluation of cases with suspected HP, particularly when evaluating women with a history of congenital heart disease.
