ADULT ECHOCARDIOGRAPHY
Adult Echocardiography (Echocardiogram) is a diagnostic test that uses ultrasound waves to make images of the heart chambers, valves, and surrounding structures. It can measure cardiac output and is a sensitive test for fluid around the heart (pericardial effusion).
Dr. Brackett and Dr. Mansour hold the distinction of adult echocardiography testamur. This requires the completion of a special competence examination to optimize skill in the performance and interpretation of cardiac ultrasound. Cardiology Associates echo lab is accredited with ICAEL.

NUCLEAR STRESS TEST – MYOCARDIAL PERFUSION STUDY

A Myocardial Perfusion Study, also known as a Nuclear Stress Test, is a non-invasive imaging test that assesses blood flow to the heart muscle (myocardium). This test may be done with or without exercise. It helps diagnose and assess conditions like coronary artery disease, heart damage from heart attacks, and blood flow patterns.
A small amount of a radioactive tracer is injected into a vein, and a special camera (gamma camera) is used to detect the tracer’s distribution in the heart. The tracer will be absorbed by healthy heart tissue, and areas with poor blood flow will show up as darker areas on the scan.
Dr. Steinberg and Dr. Patel are certified in nuclear cardiology tests.
NUCLEAR PET SCAN (Positron Emission Tomography)

A nuclear PET (Positron Emission Tomography) scan of the heart is a non-invasive imaging test that uses radioactive tracers to visualize the heart and its blood flow, helping doctors diagnose and assess heart conditions. It provides detailed 3D images of the heart’s activity, showing how well the heart muscle is working and where blood flow may be restricted. A nuclear PET scan is the fastest, most accurate way to detect heart disease and any abnormalities that could possibly have the potential for a heart attack. This test may also help your cardiologist to devise a more specific treatment plan for patients with known coronary artery disease or heart attack.
If you are scheduled for a nuclear PET scan, you will be given detailed instructions in preparation for your test, and during the testing process. If you have any further questions, please contact our offices at 805-278-4020.

HOSPITAL PROCEDURES
HEART CATHETERIZATION
![]() |
Cardiac Catheterization is a procedure used to diagnose and treat cardiovascular conditions. It is performed as an outpatient procedure in the hospital. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in the groin, neck or arm (transradial) and threaded through your blood vessels to the heart to determine if there is disease of the heart muscle, valves or coronary (heart) arteries. During the procedure, the pressure and blood flow in the heart can be measured. |
PERCUTANEOUS CORONARY INTERVENTION (PCI)
![]() |
During a cardiac catheterization if it is determined that there are blockages that would benefit from a coronary stent, then a small tube-shaped device (stent) will be placed via the already in-place catheter, to keep the blocked coronary arteries open and increasing blood flow to the heart.
Dr. Shaun Patel, Dr. Omid Fatemi and Dr. Sogomonian are Interventional Cardiologists at Cardiology Associates. |
CTO PERCUTANEOUS CORONARY INTERVENTION

ELECTROPHYSIOLOGY PROCEDURES
PACEMAKER IMPLANTATION
A pacemaker insertion is the implantation of a small electronic device that is usually placed in the chest (just below the collarbone) to help regulate slow electrical problems of the heart. A pacemaker may be recommended to ensure that the heartbeat does not slow to a dangerously low rate.
DEFIBILLATOR IMPLANTATION
The Watchman Procedure is among the newest procedures available to prevent A-fib related stroke.
PACEMAKER AND DEFIBRILLATOR BATTERY REPLACEMENT
A pacemaker battery usually lasts 7 to 8 years. When the battery runs down, a new pacemaker will be implanted. The surgery to replace the old pacemaker with a new one usually requires a local anesthetic. In most cases, your original pacemaker leads will not need to be replaced.
IMPLANTABLE MONITORING DEVICE
Reveal LINQ, Insertable Cardiac Monitor, is the world’s smallest implantable cardiac monitoring device. The procedure to implant one just takes a few minutes to perform as an outpatient. It records the heart rhythm continuously to capsure recurrent unexplained episodes of palpitations.
CATHETER ABLATION
Dr. Jonathan Dukes, and Dr. Matthew Hakimi specialize in complex ablations and are accepting new patients for first-time evaluations and new patients seeking to have a redo ablation.
Advanced Electrophysiology procedures include:

ENDOVASCULAR PERCUTANEOUS ANGIOPLASTY INTERVENTION
Endovascular Percutaneous Angioplasty Intervention – Endovenous percutaneous angioplasty, also known as percutaneous transluminal angioplasty (PTA) or endovascular angioplasty, is a minimally invasive procedure used to open blocked or narrowed veins. It involves inserting a thin tube (catheter) with a balloon on its tip into the vein, inflating the balloon to widen the vessel, and sometimes placing a stent (a small mesh tube) to keep it open. Endovascular percutaneous angioplasty intervention may include transfemoral carotid artery, subclavian, and lower extremity for claudication.
ENDOVASCULAR ABDOMINAL AORTIC ANEURYSM (AAA) REPAIR
Endovascular Abdominal Aortic Aneurysm (AAA) Repair, or EVAR, is a minimally invasive surgical procedure to repair weakened areas in the aorta, the large blood vessel that carries blood from the heart to the rest of the body. It involves inserting a stent through small incisions in the groin, guided by X-rays, to reinforce the aorta and prevent the aneurysm from bursting.
SUBCLAVIAN VEIN STENTING
Subclavian vein stenting is a minimally invasive procedure used to treat narrowing or blockage (stenosis) in the subclavian vein, a major vein in the upper body that carries blood back to the heart. Stents are small, expandable mesh tubes that are inserted into the vein to open it up and restore proper blood flow. This procedure is often performed to address conditions like venous thoracic outlet syndrome or to manage blockages caused by central lines or other medical devices.
Venous disease, deep and superficial veins including iliac vein stenting and venous thrombectomy for deep vein thrombosis
ILIAC VEIN STENTING
Iliac vein stenting is a procedure that uses a stent, a small mesh tube, to open and maintain the patency of the iliac veins, which are in the pelvis. This procedure is often performed to treat iliac vein compression, also known as May-Thurner syndrome and other conditions that lead to chronic venous insufficiency, such as pelvic congestion syndrome.
VENOUS THROMBECTOMY
Venous thrombectomy is a surgical procedure used to remove a blood clot (thrombus) from a vein, typically used to treat deep vein thrombosis (DVT) when other treatments aren’t effective. It can be performed percutaneously.
PULMONARY EMBOLISM TREATMENT
Pulmonary embolism treatment, including mechanical thrombectomy and catheter-directed thrombolysis

Varicose Veins Treatment
Endovenous Ablation is an image-guided, minimally invasive treatment for varicose veins. It uses radiofrequency or laser energy to cauterize (burn) and close the varicose veins. The results are remarkable. Patients who suffer with painful, disfiguring varicose veins now have the opportunity for a simple procedure with minimal pain.
Our vein lab founded in 2009, is located in Oxnard, CA. We treat patients who meet medically based requirements. Vein ablations are covered by most insurances.
Dr. Shaun Patel and Dr. Robert Sogomonian are board-certified in endovascular procedures.
