Dr. Niv Ad in Baltimore: Interventional Cardiologist with Same-Day Diagnostic Capacity

Dr. Niv Ad is an interventional cardiologist who diagnoses and treats coronary artery disease, performs catheterization and angioplasty, and manages acute heart attacks and complex cardiac conditions. He practices in Baltimore's medical district and holds privileges at Johns Hopkins Hospital, where he performs the majority of his interventional cases. His focus on interventional procedures sets him apart from many Baltimore cardiologists who practice general cardiology or focus primarily on medication management and monitoring.

What Dr. Ad specializes in

Dr. Ad's practice centers on catheter-based interventions. He performs diagnostic cardiac catheterization, coronary angiography, percutaneous coronary intervention (PCI) with stent placement, and manages acute coronary syndromes. His interventional focus means he is equipped to move from diagnostic imaging directly to treatment in the same procedure when appropriate, rather than referring patients elsewhere. He also manages complex cases where multiple vessels require treatment or where standard approaches may be complicated by anatomy or comorbidity. This capability is valuable for Baltimore patients with unstable angina, recent heart attacks, or multi-vessel disease who benefit from having both diagnosis and intervention available in a single visit.

Services and typical procedure costs

Diagnostic cardiac catheterization, the foundational interventional procedure, typically costs $8,000 to $15,000 depending on hospital facility fees and whether additional imaging (intravascular ultrasound or fractional flow reserve measurement) is performed. Coronary stent placement ranges from $20,000 to $40,000 depending on the number of stents and complexity. These figures reflect facility, physician, and equipment costs; actual out-of-pocket expense depends heavily on insurance and deductible status. Medicare patients generally pay a percentage of the Medicare fee schedule after meeting their deductible. Uninsured patients should ask about cash-pay rates before scheduling; many interventional programs offer modest discounts for self-pay cases when arrangements are made in advance. Verify current pricing with his office, as facility fees adjust periodically.

Most patients do not pay these fees out of pocket at the time of service; bills are processed through insurance or financial assistance. However, knowing the baseline allows you to estimate your likely responsibility based on your deductible and out-of-pocket maximum.

How Dr. Ad compares to other Baltimore interventional cardiologists

Baltimore's interventional cardiology landscape is anchored by Johns Hopkins and University of Maryland Medical Center, both of which maintain large interventional programs with multiple attending cardiologists on staff. Dr. Ad is one of several attending interventionalists at Johns Hopkins and maintains an office-based consultation practice. This arrangement gives him the advantage of dedicated one-on-one attention during office visits while leveraging Johns Hopkins' catheterization lab and imaging resources for complex cases.

For comparison, general cardiologists in Baltimore practices often focus on medication management, stress testing, and outpatient monitoring; they refer catheterization cases to hospitalists or interventionalists. Choosing Dr. Ad makes sense if you need catheter-based intervention or if you have complex multi-vessel disease where you want continuity with someone trained to perform the full diagnostic and therapeutic spectrum. Choose a general cardiologist if you have stable coronary disease controlled on medications, or if you are seeking long-term outpatient management of heart failure or arrhythmia without the expectation of a procedure. Choose a hospitalist-based interventionalist if you are hospitalized acutely and your condition requires immediate catheterization without the ability to schedule an outpatient visit first.

Who this practice suits and who it does not

Dr. Ad's practice is suited to patients with suspected or known coronary artery disease, those recovering from a recent heart attack who may need angiography, those with unstable angina, and those with complex anatomy or comorbidities that benefit from expert-level procedural decision-making. It is also appropriate for patients wanting continuity with the same physician across office evaluation and catheterization. The practice does not include primary heart failure management clinics or specialized arrhythmia care; patients with primarily arrhythmic conditions (atrial fibrillation requiring ablation, for example) should see an electrophysiologist. Patients seeking preventive cardiology or routine screening without interventional capacity can work with general cardiologists and return to Dr. Ad if a procedure becomes necessary.

What your first visit involves

New patients typically begin with a consultation in the office, usually prompted by a referral from a primary care doctor or after a stress test or imaging study has raised concern for coronary disease. You will meet with Dr. Ad to review your cardiac history, medications, and symptoms. He will perform a physical exam and review any available test results (EKGs, echocardiograms, stress tests). Based on this assessment, he may recommend a diagnostic catheterization, arrange further imaging, or initiate medical management. If he recommends a catheterization, scheduling usually takes place within one to two weeks unless the condition is acute. Expect the office visit to last 45 to 60 minutes.

If a catheterization is planned, a pre-procedure workup including blood tests and baseline kidney function is required; the procedure itself takes place at Johns Hopkins in the cardiac catheterization laboratory, not in an office setting.

Hours, parking, and logistics

Dr. Ad's office is located in Baltimore's medical district near Johns Hopkins. Office hours are typically Monday through Friday, 9 a.m. to 5 p.m., with some morning slots available. Verify current hours by calling ahead, as interventional cardiologists' office schedules sometimes shift with procedural commitments. Street parking is available but limited; metered spaces fill quickly on weekday mornings. Validated parking is generally available through Johns Hopkins facilities; ask your scheduling coordinator which garage is most convenient to the office. If you are scheduled for a catheterization at Johns Hopkins, parking information and pre-procedure instructions will be provided separately.

Dr. Ad's interventional expertise and Johns Hopkins affiliation make him a substantial resource for Baltimore patients facing complex coronary disease who benefit from having diagnosis and treatment capability in one provider's hands.
