A Facility Built on Decades of Innovative Heart Care

In 2008, Memorial Hermann celebrated the grand opening of the Larry D. Johnson Heart & Vascular Institute, a state-of-the-art, 230,000 square-foot, eight-story facility situated at the gateway to the world-famous Texas Medical Center. Since then, it has grown to become one of the top heart and vascular programs in the country.

Before breaking ground on the Institute, Memorial Hermann-TMC administrators and affiliated physicians collaborated to create a shared vision for the program – to provide patients, including those with the most advanced, complex heart disease, with a complete, end-to-end continuum of care, in one place and with a strong focus on quality.

Fortunately, they had a solid foundation on which to build. The hospital’s aortic aneurysm mortality rate was one of the lowest in the country, and their door-to-balloon time, the time between when a patient enters the ER and the time a clogged vessel is opened, was also among the lowest.

Pioneers of Interventional Cardiology

Long before the Institute opened its doors, affiliated interventional cardiologist Richard Smalling, MD, the Institute’s Director of Interventional Cardiovascular Medicine, and his colleagues were making history, leading or participating in many new device and pharmaceutical trials evaluating optimal techniques for treating ST- Elevated Myocardial Infarction (STEMI) patients, supporting the circulation and performing coronary, peripheral and carotid stenting.

They were one of the first in the U.S. to perform percutaneous valve interventions, and the first in Houston to implant a commercial transcatheter heart valve (TAVR), allowing for replacement of a diseased aortic valve without open heart surgery. To date, the team has performed nearly 2,000 TAVR implants and is the leading TAVR program in the U.S.

Cardiac Rehab

Cardiac Rehab at Woodlands Medical CenterWhether you have had a heart attack, bypass surgery, angioplasty, heart transplant or valve replacement, or have angina, congestive heart failure (CHF), a left ventricular assist device (LVADs), pacemaker or defibrillator placement, stent placement or any other cardiac-related condition, you may benefit from the cardiac rehabilitation program at Memorial Hermann.

Our goal is to help people with heart disease participate actively and confidently in their own recovery so they can return, as much as possible, to the life they enjoyed before heart disease. The cardiac rehabilitation program at Memorial Hermann The Woodlands began in 2005 and more recently moved from within the hospital, over to a larger first floor, outpatient space in Medical Plaza 4.

The cardiac rehabilitation program is a three-phase, multidimensional, medically supervised program designed to help patients recover as quickly as possible from heart disease. With a comprehensive focus on guided exercise, education and lifestyle change, the program is designed to improve overall physical and mental functioning.

Patients who participate in a cardiac rehabilitation program following heart surgery or a diagnosis of heart disease tend to have better outcomes in managing their condition.

*Physician referral is required for outpatient cardiac rehabilitation.

Aortic Center of Excellence

The Institute’s cardiothoracic and vascular surgery team is internationally renowned for aortic aneurism (AA) repair and reconstruction. It was the first in the world to perform robotic reconstructive aortic surgery and is well known for its innovative in TAA repair.

Complex Arrhythmia Center

In 2012, the Institute’s electrophysiology capabilities expanded with the introduction of the Complex Arrhythmia Center offering a complete toolkit of heart rhythm treatments that includes medications, cardioversion, catheter radiofrequency ablation and implantable devices.

Center for Advanced Heart Failure

The Center of Advanced Heart Failure employs a comprehensive approach to cardiac disease management, treating patients with innovative structural heart procedures. We are one of the leading centers in the country at managing cardiogenic shock with complex circulatory support interventions.
