Ms. Mariam Tabba Khan assumed the role of Chief Executive Officer at the not-for-profit Tabba Heart Institute (THI) on June 2nd, 2005, following the untimely passing of her philanthropic father, Mr. Abdul Razzak Tabba (S.I). Despite holding an MBA, she initially wasn't involved in her father's business pursuits during his lifetime. However, post his demise, she courageously embraced the challenge of establishing and managing the cutting-edge Tabba Heart Institute.

Under her leadership, the hospital has been unwavering in its commitment to serve both affluent and underprivileged patients. She has steered THI with dedication, fostering a culture of professionalism, humanistic-care and transparency. The Institution, an ISO 9001:2015 (Quality) and ISO 14001:2015 (Environment) certified facility, and the institution is all geared up to get ISO 45001:2015 (Safety) in the first quarter of 2024. THI is acknowledged by the College of Physicians & Surgeons Pakistan (CPSP) for delivering post-graduate training in Cardiology, Cardiothoracic Surgery, Interventional Cardiology, and Cardiothoracic Anesthesia. Additionally, THI provides a Diploma in Cardiac Nursing, recognized by the Pakistan Nursing Council (PNC).

The Institute's Research Department, generously supported by the Aziz Tabba Foundation, spearheads numerous ongoing programs, including the National Cardiovascular Data Registry (NCDR), Cardiac Registry of Pakistan (CROP). Also, THI is the only hospital in Pakistan to receive the Platinum Award from American College of Cardiology (ACC).

On the Education front, the Rehabilitation Department of Tabba Heart holds accreditation from the International Council of Preventive Cardiology and Prevention (ICCPR), offering comprehensive, high-quality rehabilitation services. Tabba Heart is the first institute outside Europe to be awarded this certification. Additionally, a Registry site has been established for the Department, sharing outcomes of rehab patients with ICCPR, ensuring adherence to international benchmarks. Moreover, the institute offers BS Medical Technology programs in Cardiovascular, Operation Theater and in Perfusion Sciences, all affiliated with the University of Karachi.

In its pursuit to expand its impact, Tabba Heart Institute has established satellite centers, serving as symbols of THI’s commitment to reach ailing hearts across various cities. These centers feature state-of-the-art consultation clinics, laboratories, pharmacies, and non-invasive diagnostic services, all conveniently housed under one roof. Notably, under her leadership, THI inaugurated a groundbreaking Emergency First Aid & Laboratory Collection Unit in June 2018 within the premises of South Asia’s largest Lucky One Mall.

Ms. Mariam Tabba Khan's fulltime commitment as CEO infuses THI's entire team with energy and drive. She epitomizes Robert Frost’s quote;

“Two roads diverged in a wood and I,
I took the one less traveled by,
..And that has made all the difference!”
