Heart Surgery: The Failing Heart Webinar

Doctors Lounge - Ask Your Medical Question

Dr. Karanam

We are pleased, to have Ravindranath Karanam MD, a cardiothoracic surgeon, for this month’s webinar. Dr. Karanam will talk about the failing heart and what medical & surgical procedures are available to help these patients. Heart failure is no stranger to the African-American community, because many common medical problems are the culprits. For example, hypertension, diabetes, obesity, COPD, alcohol abuse etc. I feel this is something we all should know more about. Join us for an informative medical discussion. As always, the Black Doctors are here for you and ready to answer all of your medical questions.
