Understand your Cardiology And Cardiac Surgery treatment options
Common questions patients ask before booking with Dr. Krishna Subramony Iyer. If your situation is different, share the details in the form below and our advisors will tailor the next steps.
When should you see a cardiologist?
Chest discomfort, breathlessness with mild activity, palpitations, family history of early heart disease, or any abnormal ECG / lipid result warrants a cardiology review. Earlier evaluation lets you avoid invasive intervention through medication and lifestyle changes.
Angioplasty vs bypass surgery - what's the difference?
Angioplasty uses a balloon catheter and stent to reopen blocked arteries through a small wrist or groin puncture (no chest incision). Bypass surgery (CABG) reroutes blood around blocked arteries using grafts. Your cardiologist recommends the right option based on how many vessels are blocked and how complex the blockages are.
What is minimally invasive cardiac surgery?
Minimally invasive cardiac surgery is performed through a 3–5 cm incision between the ribs instead of the traditional sternotomy. It preserves the breastbone, reduces blood loss, shortens hospital stays to 3–5 days, and gets most patients back to light activity within 2–3 weeks.
Is paediatric cardiac surgery safe?
Modern paediatric cardiac surgery has a >95% success rate for the most common congenital defects, even in newborns. Specialist centres with dedicated paediatric cardiac teams, ICUs and anaesthesia consistently achieve outcomes comparable to or better than adult cardiac surgery.
