Unprovoked PE occurs at a younger age, more frequently in males. It is characterized by the following significant variables: higher Wells score, lower PESI score, lower CRP, higher thrombotic burden and lower one-month mortality rate, compared to provoked PE.

Key Clinical MessageInferior vena cava (IVC) interruption is a rare condition that might pose difficulties during typical flutter ablation. When azygos vein continuation is present ablation via the femoral route could be performed. In the absence of azygos vein continuation, typical atrial flutter ablation via a superior approach from the SVC is feasible.
