James S. Lee, MD in Baltimore: Interventional Cardiologist for Complex Heart Conditions

James S. Lee is an interventional cardiologist based in Baltimore who specializes in catheter-based diagnosis and treatment of coronary artery disease, structural heart defects, and acute cardiac conditions. His practice sits within the city's network of cardiology specialists, with a focus on invasive procedures rather than medication management alone.

What interventional cardiology involves

Interventional cardiologists perform procedures inside the heart and blood vessels using catheters, imaging guidance, and specialized equipment. Unlike general cardiologists who manage conditions through medications and lifestyle changes, interventional cardiologists diagnose problems via cardiac catheterization and treat them with angioplasty, stent placement, or other device-based interventions. Lee's scope covers coronary intervention for acute heart attacks and stable angina, as well as structural repairs and complex cases that standard cardiology cannot resolve.

Services and procedure costs

Lee provides diagnostic cardiac catheterization, percutaneous coronary intervention (PCI) with stent placement, management of acute coronary syndromes, and consultation on complex structural issues. Most procedures are hospital-based rather than office-based; catheterization and intervention happen in an equipped lab with surgical backup.

Out-of-pocket costs vary sharply by insurance and procedure type. For established patients with commercial insurance, copays at the hospital facility typically range from $150 to $500 for an office visit; procedures like catheterization or stent placement may carry no additional copay if the facility is in-network, though the hospital facility fee can be substantial. Medicare beneficiaries should expect copays of $20 for an office visit. Uninsured patients should contact the hospital directly for procedure pricing, as interventional procedures easily exceed $10,000 before facility charges. Verification of current fees and insurance participation is critical before scheduling.

How Lee compares to other Baltimore cardiologists

Baltimore's larger cardiology practices include physicians at University of Maryland Medical Center and Johns Hopkins Hospital, both of which house interventional labs. These centers employ multiple interventional cardiologists and handle high patient volumes, which can mean longer appointment waits but potentially faster ER-to-catheter lab times for acute cases. Lee's affiliation and scheduling should be confirmed, as appointment availability and call-coverage roles differ by hospital setting.

Choose a high-volume academic center lab if you are having an acute heart attack and need immediate intervention; choose Lee or another individual interventional cardiologist if you have a stable condition requiring ongoing specialist care and prefer continuity with one physician. Community hospitals with smaller cardiology staffs may have longer wait times for non-emergency procedures.

Who this suits and who it does not

Lee's interventional focus suits patients with coronary artery disease, acute chest pain requiring catheterization, stent restenosis, or structural complications requiring device placement. Patients with stable angina managed by medication alone, or those seeking preventive cardiology advice without current evidence of disease, are better served by a general cardiologist and may not need referral to interventional expertise.

Those with multiple comorbidities or kidney disease should discuss procedure risk upfront; interventional procedures use contrast dye that can stress the kidneys, and Lee's team will perform pre-procedure labs to assess safety.

The first visit

For a new patient, expect a 30- to 60-minute consultation. Lee will review cardiac history, prior imaging, medications, and risk factors, and perform an electrocardiogram. If catheterization is indicated, it is typically scheduled separately at the hospital facility and requires NPO status (no eating after midnight) the night before. Plan for 4 to 6 hours at the hospital for the procedure itself, plus recovery time. Most patients go home the same day or stay overnight depending on findings and complexity.

Bring all prior cardiac imaging (stress tests, echocardiograms, previous catheterization reports) and a current medication list.

Hours, parking, and location

Office hours and location depend on Lee's hospital affiliation; confirm the address, hours, and parking availability directly with the practice, as cardiology offices move and hours change seasonally. Hospital-based catheterization labs operate 24/7 for emergencies but keep standard daytime hours for elective procedures.

James S. Lee provides a narrower but critical expertise: if you have coronary disease confirmed or strongly suspected and need intervention, he performs the procedures that medications cannot resolve.
