What Cardiology Specialists Medical Group does

Cardiology Specialists Medical Group (CSMG) is a physician-owned, private cardiology practice founded in 1992 and headquartered in Riverside, California, serving patients across the Inland Empire region through 10 office locations. The practice employs 60+ staff including 10 cardiologists with subspecialty training in interventional cardiology, electrophysiology, structural heart, echocardiography, nuclear cardiology, and women's cardiovascular care, supported by hospital partnerships with Loma Linda University Medical Center Murrieta, Inland Valley Hospital, Riverside Community Hospital, and Rancho Springs Medical Center.

The group offers a comprehensive cardiovascular service portfolio spanning general cardiology consultations, diagnostic imaging (echocardiogram, TEE, nuclear stress, MUGA, Holter, ECG), interventional procedures (cardiac catheterization, PTCA, pacemaker insertion, Watchman, PFO closure, EVAR), electrophysiology services (EP studies, cardiac ablation, cardioversion), and advanced structural heart procedures (MitraClip/TMVr, TAVR). Additional offerings include a Women's Heart Clinic directed by an ex-Duke specialist, CardioMEMS remote heart failure monitoring, cardiac calcium score screenings, and HIPAA-compliant telemedicine appointments. The practice has performed 100+ MitraClip procedures at LLUMC Murrieta, with cited clinical outcomes of 50% reduction in future heart failure hospitalizations and 30% mortality risk reduction for TMVr patients.

CSMG operates a direct-to-consumer go-to-market model, generating revenue from insurance reimbursements across a broad payer mix (Medicare, Medi-Cal, Aetna, Anthem Blue Cross, Blue Shield, Cigna, and other commercial plans), supplemented by patient self-pay Good Faith Estimates in accordance with federal law. Patient acquisition is driven by physician referrals, the practice's own website and online scheduling, a Facebook presence, Google Reviews, and a healthcare provider referral program. The practice is led by Medical Director Dr. Kaustubh V. Patankar (20+ years) and operates as an independent group with no disclosed private equity, venture, or parent company backing.

Products and services

• General Cardiology Services Comprehensive cardiovascular care including diagnosis and treatment of heart conditions such as arrhythmias, coronary artery disease, heart failure, and heart valve disease for adult patients in the Inland Empire.
• Transcatheter Mitral Valve Repair (MitraClip / TMVr) Minimally invasive procedure to repair the mitral valve using a small clip device, allowing the valve to close more completely and restore normal blood flow through the heart, for patients with mitral regurgitation who are not candidates for open-heart surgery.
• Transcatheter Aortic Valve Replacement (TAVR) Minimally invasive heart procedure to replace a narrowed aortic valve that fails to open properly (aortic valve stenosis), allowing faster recovery than open-heart surgery.
• Cardiac Ablation Non-invasive catheter-based procedure to correct irregular heart rhythms (arrhythmias) by scarring or destroying tissue in the heart that triggers abnormal rhythms.
• Pacemaker Insertion Battery-operated device implantation under the skin with wires connecting to the heart to regulate slow or irregular heartbeats.
• Cardiac Catheterization / Coronary Angiogram Diagnostic imaging procedure to visualize heart arteries and blood flow using a catheter inserted through blood vessels.
• Cardioversion Procedure to restore normal heart rhythm by delivering electric shocks to the heart through electrodes placed on the chest.
• Percutaneous Transluminal Coronary Angioplasty (PTCA) Balloon catheter procedure to widen narrowed or blocked coronary arteries.
• Watchman Procedure Implant procedure to reduce stroke risk in patients with atrial fibrillation who cannot use blood thinners.
• PFO Closure for TIA/Stroke Procedure to close a patent foramen ovale (hole in the heart) to prevent recurrent strokes.
• Endovascular Aortic Repair (EVAR) Minimally invasive procedure to repair abdominal aortic aneurysm using a stent graft inserted through blood vessels.
• Echocardiogram Ultrasound test using sound waves to create images of the heart's structure, size, and pumping function.
• Transesophageal Echocardiogram (TEE) Ultrasound imaging of the heart from inside the esophagus to obtain detailed images of heart structures and function.
• Electrocardiogram (ECG/EKG) Recording of the heart's electrical impulses to detect heart rhythm abnormalities and electrical activity issues.
• Electrophysiology (EP) Studies Tests that assess the heart's electrical system to diagnose abnormal heart rhythms and determine treatment needs.
• Exercise Stress Test Treadmill-based test measuring heart function during exertion to detect reduced blood flow in coronary arteries.
• Nuclear Stress Test Imaging test measuring blood flow to the heart at rest and during stress using a radioactive dye to detect coronary artery disease.
• MUGA Scan Nuclear medicine test using a radioactive tracer to evaluate how well the heart pumps blood and assess ventricle function.
• Holter Monitoring Continuous 24-hour ECG recording worn during daily activities to detect intermittent heart rhythm abnormalities.
• Tilt Table Study Diagnostic test to evaluate the cause of fainting (syncope) by measuring heart rate and blood pressure changes with position changes.
• Telemedicine Services Phone or video doctor appointments using HIPAA-compliant secured systems for new and established patients, particularly utilized during COVID-19.
• Cardiac Calcium Score Screenings Non-invasive CT screening to detect cholesterol buildup and calcified plaque in heart arteries and estimate heart attack risk.
• Remote Heart Failure Monitoring (CardioMEMS) Remote monitoring technology using a pulmonary artery pressure sensor to detect heart failure worsening before symptoms appear.
• Women's Heart Clinic Specialized cardiovascular care for women including prevention, cardiovascular imaging, and women's cardiovascular health awareness, directed by Dr. Mimi Sen Biswas.

Quantifiable outcome

• 50% of patients who undergo TMVr require less future hospitalizations for heart failure, and it reduces the risk of mortality by 30%
