Services
Heart Rhythm Disorders
Our electrophysiology specialists diagnose and treat complex heart rhythm conditions like AFib and ventricular tachycardia using advanced mapping systems and ablation techniques. Patients receive personalized treatment plans combining medication management, implantable devices, and minimally invasive procedures. With board-certified expertise in clinical cardiac electrophysiology, we improve quality of life for patients with irregular heartbeats.
Vascular Surgery
We address peripheral vascular disease, aortic aneurysms, and other circulation issues through surgical and endovascular approaches. Our vascular surgeons perform arterial bypasses, stent placements, and minimally invasive procedures using state-of-the-art imaging. Patients benefit from comprehensive management of leg pain, swelling, and circulation-related complications across seven Northern Virginia locations.
Interventional Cardiology
Our interventional cardiologists perform coronary angioplasty, stent placement, and structural heart procedures in-office using advanced catheterization labs. This eliminates hospital stays for treatments like TAVR valve replacement and MitraClip implantation. Patients receive faster recovery times and reduced costs compared to traditional surgical approaches for blocked arteries and heart defects.
Remote Patient Monitoring
This program enables continuous heart health tracking through wearable devices that transmit vital data to our care team. Patients with heart failure, pacemakers, or post-surgical needs receive proactive interventions based on real-time metrics. The service reduces hospital readmissions by allowing early detection of irregularities and timely treatment adjustments.
Preventive Cardiology
We offer risk assessments, cholesterol management, and lifestyle counseling to prevent cardiovascular disease progression. Our preventive programs include advanced lipid profiling, calcium scoring CT scans, and personalized exercise/nutrition plans. Patients receive education on managing hypertension, diabetes, and other risk factors to maintain long-term heart health.

My husband has been a patient of Dr. Hamid Taheri's since 2006. We truly feel that he saved my husbands life by doing the appropriate testing and necessary procedures from the offset of his problems. He has always been provided the highest level of medical care at this facility by Dr. Taheri & staff. We feel the entire staff at this office are absolutely the best. We recently had to go in for his annual appointment/checkup and once again had the pleasure of working with a great group of individuals. Starting with setting up the appointments with Natasha in customer service who went above and beyond to assist us, to arriving at the office and being greeted in a very professional and friendly manner by Shantel who could not have been more helpful, to the techs in the echo cardiologist department and then with Dr. Taheri and his assistant.

Their accounting department staff, Arlene and Shelly are also extremely helpful in answering all of your questions and assisting you however they can. So Kudos to the entire team of Carient Heart & Vascular, Manassas, Va. location.

I'm well pleased with the timely diagnosis, quick response, and quality personal care from all levels of administrative staff to surgeon. This was not my first 'rodeo' with my cardio surgery, but I rate it at the top of the stack. Thank you, Dr. Lee.

My first visit with Dr. Karimi was scary hearing I needed a Stent. He was extremely kind and considerate of my feelings. He reassured me of the procedure and outcome. After having the procedure, he was very caring and let me know everything that had been done. Also, I went in for a check before a long vacation, which he was reassuring that I was fine and even sent me an email telling me to enjoy my trip! I will continue using Carient Heart & Vascular with the utmost confidence.
