question: Hello doctor, I am a 26 year male. I have done echo and tee test. The result is ACHD, SS, LC, 30x28 mm OS ASD~2:1 L-->R SHUNT, PV AND IVC rim not clear, good BV function, mild PAH, no HF, SR and FCI. Cardiology doctor suggested open heart surgery for correction of ASD and another doctor said that catheter procedure is not suitable for my ASD. Is it a dangerous situation? Is surgery needed? What if it is not cured? I have a chronic cough for the last six months. The respiratory doctor said that it is an allergic symptom. Is there any connection between cough and OS ASD? I am so worried. I request that you please reply and give me proper advise.
