Dr. Chow was assigned to me when I was admitted to Advocate Condell in Libertyville for heart failure. Dr. Chow was not satisfied that the reason for my heart failure was as simple as it may have seemed. He did test after test until a double-sided angiogram revealed severe mitral valve leakage that was not detected on an echocardiogram or a trans-esophageal echo. His refusal to stop until he nailed the answer saved my life as it resulted in a mitral valve repair. Dr. Chow has a great bedside manner, is genuinely interested in me as his patient, and takes all the time necessary during appointments. Highly recommended.
