Does a left bundle branch block affect complication of a cosmetic surgery?

Your heart may beat irregularly under general anesthesia.  You should see a cardiologist prior to pursing aesthetic surgery.   I also recommend an in-office examination as well as a detailed discussion with a surgeon who you are comfortable with.   Finally, make sure your surgeon is a Double-Board Certified Plastic Surgeon certified by the American Board of Plastic Surgery (ABPS), a member of the American Society of Plastic Surgery (ASPS), a member of the American Society of Aesthetic Plastic Surgery (ASAPS), and a fellow of the American College of Surgeons (FACS).Best,Dr. DesaiBeverly Hills Institute for Aesthetic Plastic SurgeryHarvard Educated, Beverly Hills & Miami Beach TrainedDouble Board-Certified, Double Fellowship-Trained Beverly Hills Plastic Surgeon

Hi. Conduction abnormalities of the heart do not necessarily preclude a breast augmentation. However, I would require a medical clearance to include a 24 hour holter monitor if your cardiologist or my anesthesiologist deemed it necessary. " An ounze of prevention is worth a pound of cure". Patient safety first and foremost.Always seek out the opinion of a surgeon certified by the American Board of Plastic Surgery with years of experience in cosmetic breast surgery. Furthermore request to see before and after photos of previous patients by that doctor....not a clinic or surgery center. Do your homework......research and verify the doctor's credentials. Have they had problems with the Board of Medicine, disciplinary or otherwise. Any law suits? 
How about the center, clinic or facility? Are they accredited by a national organization or do they just have State approval. Understand that at the current time, there are three nationally recognized organizations responsible for the highest levels of patient safety, AAAASF, AAACH and JCHO. You owe it to yourself to position yourself for the best possible results but under the most stringent safety regulations, If you have kids, even more so.
How about anesthesia? Will you have a medical doctor certified by the American Board of Anesthesiology or a certified nurse anesthetist (CRNA)? Understand that there is no substitute for research. Cosmetic surgery, no matter how simple it may be to the patients, are invasive procedures and as such carry certain risks and complications.
In our office, as in others, we use TouchMD which is a web based program in which patients have the ability to load their picture unto the program. I then evaluate them and can actually draw on the picture to show a potential patient where the incisions would be located and how the procedure is to be realized. It's all done to comply with HIPPA which is the federal law that protects the patient's medical information. Look them up.
good luck, Dr PG

Thank you for your question. I would recommend speaking to your plastic surgeon and anesthesiologist about this. Regards, 

You do not mention your age or if you have had any heart problems. Assuming you are otherwise healthy, as you indicate, and the block is not affecting you , you probably can have safely have surgery. The concern is how your heart will function under anesthesia. You should get a clearance for anesthesia from your physician or heart doctor before proceeding.

As you may know, the LBBB is an electrical / conduction problem in the heart.  It makes it much more tricky to sort out what is going on with your pre-op EKG.  For this reason, clearance by a cardiologist is usually recommended, even in someone who has a good exercise tolerance.

Best to discuss this with your PS and your anaesthetist. You will probably need an ECG and advice but  this isn't an absolute contra-indication for surgery. 

 I would strongly recommend that you obtain a preoperative clearance with a cardiologist to see if you’re  a good candidate for surgery. You should have him or her thoroughly discuss with you possible risk of surgery. I hope you find this information useful. For more information please watch the enclosed video. 

Most surgeons would require a written cardiac clearance from your cardiologist prior to operating upon you, even for a breast augmentation. So return to see your cardiologist to discuss obtaining this clearance.. 

this would be up to the anesthesiologist who will be taking care of you. If you have clearance from your cardiologist, it will likely be fine but you will need to speak to the anesthesiologist your surgeon uses.
