Ali Zaidi, MD

The pediatric cardiologist that many Upper East Side families rely on is tucked inside 1468 Madison Avenue on the third floor of the Annenberg Building. This practice doesn’t just screen for murmurs; it tracks rhythms, digs into family history, supervises sports clearances, guides post-surgical care, and manages outpatient infusions—all in one northern Manhattan footprint. When scans and consults overlap, the same team coordinates further testing without redirection. Algorithms shift, growth milestones change, and new murmurs appear; that’s why the clinic houses echo, ECG, Holter monitoring and stress testing under one roof. Concerns that flare at 4 p.m. on a weekday don’t wait for tomorrow, so same-day appointments open when the schedule allows. Parents Skype grandparents mid-visit with printouts already in hand. Reach the practice at (212) 241-1382 or swing by the map for directions to the third-floor suite. From Fifth to Park, it’s a straight walk; the elevators are just past the corner coffee cart.
