Hello. We will go through your questions one by one,
1. Two echocardiograms done the same day can be very different depending who perform and read the exam. Obviously in your case one is right and the other one wrong. If the one that didn't show an aneurysm was done by a better operator I'll stick to that report.
2. There is no specific limit in the amount of ablations that a patient can have. Although, if an arrhythmia recurs despite having more than 3 unsuccessful ablations, makes you think that would be reasonable to try a different approach.
3. If the palpitations recur after having an ablation, the first thing is to prove that the patient is having the same arrhythmia before the ablation and is not something else.
4. A PFO can produce a paradoxical embolism (a venous clot that gets in the arterial system through the PFO and produce a thrombosis). Aspirin is the usual initial approach and if the patient has an embolism is started on blood thinners (i.e. Coumadin). There is no evidence at this time that closing a PFO is superior to aspirin or Coumadin. The procedure is usually indicated if the patient has an embolism under Coumadin treatment. The percutaneous procedure (Amplatzer) is very expensive and has it owns risks, so let's stick to the aspirin.
5. Your blood pressure and heart rate while dancing will depend on what type of dancing you are doing (i.e. the amount of energy required to do the exercise). If you don't have shortness of breath while dancing I won’t worry.
