Dr. Daniel Hermann, MD

Dr. Hermann is a native Texan who subspecializes in interventional and structural cardiology. A leader and innovator, he is passionate about caring for his patients and takes pride and joy in his day to day work. He has extensive training and experience in multiple catheter based cardiac procedures and was instrumental in bringing many of those approaches and technologies to the Memorial City and Cypress Memorial Hermann campuses. He has been named and is the current Director of Structural Cardiology at Memorial Hermann Memorial City.

Dr. Hermann treats patients with a vast array of cardiovascular conditions including valvular heart disease, coronary disease, congestive heart failure, and arrhythmia including atrial fibrillation. He preferentially performs heart catheterization procedures using the radial artery in the wrist (instead of the leg). This allows for faster recovery times, lower complication rates, and improved patient comfort. He has performed complex coronary stenting on many patients who were poor candidates for bypass surgery. He has extensive experience in treatment of complex coronary anatomy including chronic total occlusions (coronary CTO), heavily calcified coronaries requiring atherectomy, left main coronary disease, and use of percutaneous mechanical cardiac support devices (including Impella).

He is one of only a handful of physicians in the Houston area with extensive structural cardiology experience. This relatively new field is focused on finding the most effective, but also least invasive treatment option for patients. This includes percutaneous closure of the left atrial appendage (using the Watchman device), transcatheter aortic valve replacement (TAVR), transcatheter mitral valve edge-to-edge repair (with MitraClip), percutaneous PFO and ASD closure, and alcohol septal ablation for treatment of hypertrophic cardiomyopathy. With these breakthrough therapies, patients are typically able to avoid the need for open heart surgery, general anesthesia and may go home the same or next day. Recovery times are generally just the minimal time needed to allow the small catheter insertion site to heal!

Understanding that today’s patients have complicated medical histories, Dr. Hermann frequently collaborates across medical specialties with cardiac surgeons, primary care physicians, neurologists, noninvasive cardiologists, nurse practitioners and more. Furthermore, he firmly believes in the strength and importance of establishing meaningful patient-physician relationships. This partnership and trust is critical to successful long term outcomes. Cardiac disease can be daunting, but Dr. Hermann is committed to clinical excellence and patient care.

Dr. Hermann is the father of 3 young boys. His wife is a pediatric surgeon. He is an avid basketball player and believes that the most effective long term treatment strategy for heart disease is centered around a heart healthy diet and lifestyle.
