Pulmonary embolus and right atrial thrombus trapped in a patent foramen ovale is an unusual, rare condition. We report a case of impending paradoxical embolism with pulmonary embolism, in which a thrombus entrapped in a patent foramen ovale was detected. To our knowledge, this is the first case in the literature in which 'thrombus-in-transit' was detected in the right atrium both before and after entrapment in a patent foramen ovale.

Our study revealed that in active elderly patients with complete heart block, DDD pacing and VVIR pacing yielded similar improvements in QoL and exercise performance. However, after a short follow-up period, we noted that VVIR pacing caused significant left atrial enlargement and impaired left ventricular diastolic functions.
