Dignity Health Arizona Heart Services

• Cardiac Imaging

  Cardiovascular imaging is used to evaluate and aid in diagnosing cardiac issues or concerns. Care providers frequently request diagnostic testing to gather more information about specific cardiac or vascular disease symptoms. Main types of cardiac imaging:

  • Echocardiogram (Echo)
  • Cardiac Computed Tomography (CT Scan)
  • Nuclear Cardiac Stress Test
  • Coronary Angiogram, Cardiac MRI
  • Cardiac Positron Emission Tomography (PET)
  • Single Photon Emission Computed Tomography (SPECT)

• Cardiac Electrophysiology: Expert Care for Heart Rhythm Disorders

  If you're experiencing symptoms like a fluttering sensation, a heart that beats too fast or slow, dizziness, or shortness of breath, these could be signs of an irregular heart rhythm (arrhythmia). Your doctor may refer you to a cardiac electrophysiologist – a highly specialized heart doctor focused on your heart's electrical system.

   

  At Dignity Health, our expert cardiac electrophysiology specialists are dedicated to diagnosing and treating a wide range of heart rhythm issues. By focusing on your heart's electrical activity, we aim to reduce your symptoms, improve your quality of life, and lower your risk of complications like blood clots. These advanced treatments even hold the potential to permanently resolve complex rhythm problems like atrial fibrillation (AFib). Our comprehensive Electrophysiology services include:

  • Electrophysiology (EP) Studies: Detailed mapping of your heart's electrical activity.
  • Catheter Ablations: Procedures to correct faulty electrical pathways.
  • Pacemakers & Defibrillators: Devices to regulate heart rate and prevent dangerous rhythms.
  • Loop Recorders: Small, implantable devices for long-term heart monitoring.
  • Cardiac Resynchronization Therapy (CRT/Biventricular) Implantations: Advanced pacing for heart failure.
  • Tilt Table Testing: To evaluate causes of fainting or lightheadedness.

• Cardiac Rehabilitation

  Cardiac rehabilitation is a proven, evidence-based practice that has been shown to improve outcomes for cardiac patients by teaching positive health choices. Cardiac Rehabilitation Program can help support recovery, reduce risk for further cardiovascular disease, and increase overall health and well-being.

  If you are at high-risk for or have been diagnosed with heart disease, it is important to take action to prevent future problems with your heart. Your cardiologist or primary care doctor can write and sign a referral to the Cardiac Rehabilitation Department.

• Comprehensive Vascular Services

  Your vascular system—comprising your veins, arteries, and other blood vessels—is crucial for circulating blood throughout your body. Vascular disease occurs when these vessels become blocked, weakened, or damaged, impacting vital blood flow. Conditions can range from common concerns like spider veins to life-threatening issues such as blood clots, or chronic conditions that require ongoing management.

  At Dignity Health, our interventional cardiovascular team specializes in diagnosing and treating a wide spectrum of venous and arterial diseases. Whether conditions appear acutely or develop chronically over many years, our experts are equipped to provide the comprehensive care needed to restore and maintain your vascular health.

• Interventional Cardiology

  Interventional procedures are minimally invasive, catheter-based treatment options for cardiology conditions throughout the body. That means, they do not require open surgery. Minimally invasive cardiology treatments have many benefits, including:
  

  • Shorter hospital stays
  • Faster recoveries
  • Less pain
  • Better patient outcomes

• Pulsed Field Ablation (PFA): Advanced Treatment for AFib

  Atrial Fibrillation (AFib) is a serious and increasingly common heart rhythm disorder, affecting millions of Americans. By the end of this decade, the American Heart Association projects over 12 million individuals will live with AFib. This condition significantly raises the risk of severe complications, including blood clots, stroke, heart failure, and other cardiac issues. Timely and effective treatment is therefore critical for managing AFib and preventing these life-altering consequences.

   

  Dignity Health is at the forefront of AFib treatment with Pulsed Field Ablation (PFA), an innovative alternative to traditional thermal ablation techniques.

   

  What is Pulsed Field Ablation (PFA)?

  PFA is an FDA-approved, minimally invasive procedure designed to treat AFib. Unlike conventional thermal ablation (which uses heat to alter heart tissue), PFA utilizes precise pulsed electrical fields. These fields are delivered through an ablation catheter to specifically interrupt the irregular electrical pathways in the heart that trigger AFib.

   

  One of PFA's significant advantages lies in its precision. The pulsed electric fields efficiently isolate the pulmonary veins and surrounding structures – key areas involved in AFib – potentially reducing the risk of unintended impact on adjacent healthy tissues during the treatment. This advancement offers a new level of safety and effectiveness for patients seeking treatment for AFib.
