Structural Heart Program

Heart Valve Implantation Without Surgery

Patients with aortic stenosis (narrowing of aortic valve) develop significant cardiac symptoms when their aortic stenosis become severe. Such patients should be considered for aortic valve replacement. Whereas open-heart surgery in patients with aortic stenosis is currently still the elective procedure of choice, a high percentage of patients with aortic stenosis may be considered too high risk for this conventional surgery. For those patients, a new and innovative catheter-based procedure called Structural Heart Intervention may provide a healthy alternative to open-heart surgery.

Dr. Heidar Arjomand, the Medical Director of the "Structural Heart Disease Interventions" Program at Aventura Hospital and Medical Center, and his team are able to replace or repair certain heart valves with minimally invasive techniques using dedicated catheters. Such procedures are known as percutaneous or transcatheter valve replacement or repair. These artificial valves are purified and attached to a metallic frame, similar to that of a stent. The device is compressed over the surface of a balloon catheter. By creating a small incision at the level of the groin, Dr. Arjomand and his structural heart disease team can advance these catheters through the femoral artery or femoral vein to the heart. Once in place, the balloon is inflated at high pressure to expand and deliver the new artificial valve, which has now substituted the damaged valve. The balloon and catheter is then removed. In other words, the artificial valve, once delivered inside the native one, assumes its function and replaces it without having to remove it.

Dr. Arjomand explains that there has been significant progress over the past 10-15 years in the field of transcatheter valve therapy which is the fundamental reason to have a dedicated "Structural Heart Disease" team. Since its inception and following the very first human percutaneous valve replacement over 15 years ago, thousands of patients world-wide have benefited from this new technology.

Candidates for Transcatheter Aortic Valve replacement (TAVR) may include:

  • Patients with aortic stenosis that are inoperable (meaning that they are at extreme risk for conventional open heart surgery)
  • Patients with aortic stenosis that are simply at high-risk for conventional open heart surgery

Some other examples of heart conditions that can be treated through the Structural and Adult Congenital Heart Intervention Program include:

Meet Our Medical Director

  • Dr. Heidar Arjomand-Fard, MD

    Dr. Heidar (AJ) Arjomand is Medical Director of Structural Heart Disease Intervention at Aventura Hospital & Medical Center. He is an experienced interventional cardiologist with board certifications in Interventional Cardiology and Endovascular Medicine. He completed one year of advanced additional training in Structural Heart Disease Interventions at Henry Ford Hospital in Detroit, Michigan. Dr. Arjomand is one of few Interventional Cardiologist who has dedicated fellowship training in Structural Heart Disease Interventions such as Transcatheter Aortic Valve Replacement (TAVR), Transcatheter Mitral Valve Repair (TMVR), and Percutaneous Left Atrial Appendage Closure (LAAC). Given his advanced training, Dr. Arjomand and his Structural Heart Disease team use innovative, minimally catheter-based techniques to treat multiple heart conditions including aortic stenosis (narrowing of aortic valve). Through procedures similar to routine cardiac catheterization, Dr. Arjomand and his team are able to repair multiple other heart defects including leaky heart valves without requirement for traditional open heart surgery. Such treatment modalities are often associated with quicker recovery and better outcomes. Dr. Arjomand also has advanced training and board certifications in Vascular & Endovascular Medicine. He and his highly skilled cardiovascular team offer advanced, minimally invasive treatment for patients with Peripheral Arterial Disease (PAD), Abdominal Aortic Aneurysms (AAA), and Carotid Artery Disease. Dr. Arjomand is a board-certified interventional cardiologist who also treats patients with heart attack (myocardial infarction = MI). He and his dedicated cardiovascular team are involved in the treatment of patients with myocardial infarction by performing emergent cardiac catheterization and percutaneous coronaru intervention (PCI) to open blocked arteries in the heart.
