Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
at my last echo (in december, one month after my second PE) I had elevated pressure in the pulmonary arteries plus mitral and tricuspid valve insufficiency. My cardiologist and lung doctor said that this kind of deficit is quite normal if you have had a PE a few months before. I don't think you should be concerned about it if your doctors were not. Mild dysfunctions are present even in fully healthy people and cause no problem at all.
Best of luck!
