Sir,

We read with pleasure the comments on our recent paper, entitled “Outcome of pulmonary embolism and clinico-radiological predictors of mortality: Experience from a university hospital in Saudi Arabia”.[1] We agree that signs of right ventricular dysfunction in computed tomography scan can be more predictive of outcome than the embolic burden based on obstruction score and localization, however in our study we assessd right side overload using echocardiographic criteria.[2] Biochemical markers of myocardial injury, e.g., troponin and pro-brain natriuretic peptide, although they are non specific, can be useful as prognostic markers in normotensive patients[3] and we acknowledge this to be a limitation of our study.
