Hello and welcome, I completely understand and share the issue. The case needs to be managed in consortium by a gynecologist and cardiologist both. If it is possible get her hysterectomy done first. I am not sure about why she is having vaginal bleeding at 73 years. Is it a cancer or some non cancerous cause. This is because cancer surgery would be extensive and require prolonged anesthesia. Once the hysterectomy is done, then cardiac surgery can be undertaken as soon as the wound heals. Then she can be put on blood thinners. Another way is to ask your gynecologists for any other procedure to control bleeding like uterine artery embolisation etc depending upon the reason for bleed. Get an open surgery rather than a laproscopy as it is quicker. The timing of surgery will be decided only by a cardiologist after assessing her risk. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have. Dr Madhuri Bagde Consultant Obstetrician and Gynecologist
