Who We Are
What is Connected Cardiovascular Care?
Connected Cardiovascular Care Associates (C3) is a leading cardiovascular practice with offices in Dallas and Rockwall, Texas. Our team of expert cardiologists, led by Dr. Tony S. Das, a nationally recognized vascular surgeon and interventional cardiologist, provides comprehensive heart and vascular care with a focus on prevention, early detection, and advanced treatment. Alongside Dr. Das, our physicians—Dr. Nicholas C. Macpherson, Dr. Imran Baig, Dr. Azizul Rehman, Dr. Ken Johnson, and Dr. Syed Saad—bring specialized expertise in non-invasive cardiology, interventional and structural cardiology, vascular interventions, cardiovascular prevention, and cardiac electrophysiology. Together, we deliver personalized care for conditions ranging from coronary artery disease and valvular disease to heart rhythm disorders and vascular disease.
C3 is transforming cardiac care with state-of-the-art imaging and diagnostic technology. We proudly utilize Arineta’s SpotLight, the world’s first dedicated cardiovascular CT scanner, to provide unparalleled accuracy in cardiac imaging. Our advanced services include calcium scoring to measure coronary plaque buildup and for highly detailed evaluation of heart disease. To further enhance diagnostic precision, we integrate AI-powered tools such as HeartFlow, Cleerly, and Elucid, which analyze coronary imaging to provide deeper insights into plaque, blood flow, and vessel health. These technologies allow our physicians to detect disease earlier, guide more precise treatment strategies, and improve long-term outcomes—all with a patient-centered approach.
At Connected Cardiovascular Care Associates, our mission is to combine innovative technology, world-class expertise, and compassionate care to deliver the highest quality cardiovascular treatment for patients across the Dallas–Fort Worth area.
Nationally Recognized For
Superior Cardiovascular Care
Comprehensive Management
Connected Cardiovascular Care Associates provides comprehensive management for heart and vascular disease, including coronary artery disease, peripheral arterial disease, and venous disorders. Our cardiologists deliver individualized treatment plans that address both acute and long-term cardiovascular needs. With advanced diagnostic tools and minimally invasive therapies, we help patients in Dallas and Rockwall achieve better heart health and improved outcomes.
Interventional Certification
C3 is proud to offer the highest level of interventional expertise for cardiac and vascular procedures. Dr. Tony Das was the first cardiologist in Dallas to obtain specialty board certification in Peripheral Vascular Procedures, earning distinction through the Society of Vascular Medicine and Biology Endovascular Interventional Boards. Our interventional team continues to set the standard for excellence in minimally invasive heart and vascular care.
Diagnostic Services
Our practice provides a full range of advanced cardiovascular diagnostic services, including treadmill and chemical stress testing, echocardiography, nuclear imaging, and vascular studies such as abdominal aneurysm screening and venous insufficiency evaluations. C3 is the only cardiovascular practice in Dallas to offer nuclear stress testing while sitting up, a unique option that reduces artifacts and is more comfortable for patients with claustrophobia in traditional CT or nuclear scanners. These tools allow our cardiologists to detect disease earlier and guide more effective treatment.
Second Opinion
For patients seeking alternatives to open-heart or vascular surgery, C3 offers a trusted second opinion clinic. Dr. Tony Das has evaluated thousands of patients over his 20+ year career, often guiding them toward less invasive options that improve outcomes and reduce recovery time. Our second opinion services provide clarity, innovative treatment choices, and peace of mind for individuals navigating complex cardiovascular decisions.
Digital Health
Connected Cardiovascular Care Associates leads the way in digital health, using wearable sensors and remote monitoring to track patients’ cardiovascular health between visits. Our team leverages advanced technology to detect irregular heart rhythms such as atrial fibrillation and monitor conditions like congestive heart failure through programs such as Halo, which tracks blood pressure, weight, and rhythm trends. This proactive approach helps reduce emergency room visits and hospitalizations while keeping patients closely connected to their cardiology team from anywhere in the world.
Preventive Cardiology
At C3, our preventive cardiology program focuses on identifying cardiovascular risk early and creating personalized strategies to improve long-term heart health. We work closely with key partners, including blood testing services, registered dietitians, and nutritionists, to design custom plans for weight management, strength building, and recovery after a heart attack or surgery. Our Dallas cardiologists help patients set achievable goals to protect their heart health and improve overall quality of life.
