Cardiovascular Conditions Addressed

Dr. Dennis Walker addresses a wide range of Cardiovascular health concerns, including:

• Ventricular Septal Defect: VSD is a birth defect where there's an opening between the heart's two lower pumping chambers.
• Typical Atrial Flutter: Typical atrial flutter is characterized by a very rapid and regular heart rhythm originating from the atria.
• Chronic Pulmonary Heart Diseases (incl. Pulmonary Hypertension): Chronic pulmonary heart diseases encompass a group of heart problems stemming from chronic lung illnesses, often manifesting as elevated pressure in the blood vessels leading to the lungs.
• Acute Deep Vein Thrombosis (DVT): Acute deep vein thrombosis (DVT) is a blood clot that forms in a deep vein, usually in the leg.
• Sinus Tachycardia: Sinus tachycardia means your heart rate is elevated above the normal range, but the rhythm is otherwise regular and originates from the sinoatrial node.
• Mitral Valve Regurgitation: Your heart's mitral valve may not be closing properly, causing blood to flow in the wrong direction; this is called mitral valve regurgitation.
• Ebstein: Ebstein's anomaly is a heart condition where the tricuspid valve, one of the heart's valves, is malformed.
• Thoracoabdominal Aortic Aneurysm: A thoracoabdominal aortic aneurysm is a serious condition where a part of your aorta, the main artery, becomes enlarged and weakened in your chest and belly.
• Peripheral Arterial Disease of Extremities: Peripheral artery disease affects blood flow to your extremities, potentially causing pain, numbness, or cramping, especially with activity.
• Heart Disease: Heart disease encompasses various problems that impact the heart's ability to pump blood efficiently.
• Heart Block: Heart block is a problem with the electrical signals that control your heart's rhythm.
• Atherosclerosis of Aorta: The aorta, your body's main artery, has a hardening and narrowing due to plaque buildup, a condition called atherosclerosis.

Cardiovascular Services Provided

Dr. Dennis Walker offers a range of services to support your Patient's health and well-being, such as:

• Cardiac Imaging: Doctors use cardiac imaging tests to check the health of your heart and see how well it's pumping blood.
• Coronary Angiogram: A coronary angiogram is a minimally invasive procedure to visualize the arteries supplying blood to your heart muscle.
• Cardioversion: A cardioversion procedure uses electricity to convert an abnormal heart rhythm back to a normal, steady beat.
• Peripheral Arterial Disease Screening (PAD): This screening assesses whether you have peripheral artery disease (PAD), a condition affecting blood circulation in your extremities.
• Cardiovascular Stress Test: A cardiovascular stress test helps doctors evaluate your heart health by observing how it works under stress.
• Dobutamine Thallium Stress Test: This non-invasive test uses a medication to simulate exercise and a radioactive tracer to image your heart, detecting areas that might not get enough blood.
• Cardiac Myocardial Perfusion Imaging: A cardiac myocardial perfusion imaging scan uses radioactive tracers to assess blood flow to your heart muscle, helping detect blockages.
• HeartAware Online Risk Screening: This online HeartAware screening helps you understand your heart health and potential needs for preventive care.
• Cholesterol Screening: This service helps check your cholesterol levels to assess your heart health.
• Nuclear Stress Testing: Nuclear stress testing uses a small amount of radioactive material and an exercise test or medication to show how well your heart is working during stress.
• Vascular Duplex Ultrasonography and Plethysmography: A painless procedure, Vascular Duplex Ultrasonography and Plethysmography employs ultrasound and plethysmography to evaluate blood vessel health and identify potential blockages.
• Chest CT (incl. Heart and Lungs): This chest CT scan, including your heart and lungs, helps your doctor evaluate your cardiovascular health.

Frequently Asked Questions

Here are answers to some common questions about care with Dr. Dennis Walker:

What is a Cardiologist?

A cardiologist is a doctor specializing in the heart and blood vessels. They diagnose, treat, and prevent heart conditions like coronary artery disease, heart failure, arrhythmias, and high blood pressure.

What should I expect during my first visit with Dr. Dennis Walker?

Your first visit with Dr. Walker will involve a detailed discussion of your symptoms, risk factors, and family history. A physical exam, including an electrocardiogram (EKG), will follow. Further testing, such as an echocardiogram or stress test, may be recommended depending on your individual needs.

Does Dr. Dennis Walker accept my insurance?

Dr. Walker's office accepts a variety of insurance plans. To confirm your specific coverage for consultations and procedures, please call our office directly with your insurance information.

What is a cardiac catheterization or angiogram?

Cardiac catheterization, or angiogram, is a minimally invasive procedure used to diagnose and treat heart conditions. A thin tube (catheter) is guided to the heart to measure pressures and visualize the coronary arteries with dye, which helps identify blockages.

I have a family history of heart disease. How can I be proactive?

We commend you for being proactive about your heart health. A preventive cardiology consultation with Dr. Walker will involve a thorough risk assessment, potentially advanced lipid testing, and the creation of a personalized plan for diet, exercise, and lifestyle changes to minimize your future risk.

How does Dr. Dennis Walker treat high blood pressure (hypertension)?

Dr. Walker employs a comprehensive approach to managing hypertension, including personalized lifestyle counseling (diet, exercise, stress reduction) and, when necessary, the prescription of appropriate medications. The goal is to achieve and maintain healthy blood pressure levels to prevent potential long-term complications.

What is a cardiac ablation?

A cardiac ablation is a procedure used to treat heart rhythm problems. It involves using catheters to deliver energy to specific areas of the heart causing irregular rhythms, correcting the electrical signals. This helps restore a normal heart rhythm.

Why do I need to wear a Holter or event monitor?

A Holter or event monitor is a portable EKG device worn for one or more days to record your heart's rhythm during normal daily activities. This helps us detect any arrhythmias that might not show up during a standard office EKG.
