MTIMA means “heart” in Chichewa, and we are an organization of professionals working to advance cardiovascular program to improve lives in Malawi through medical education, social advocacy, and diagnostic testings.

Our Story

Action with Vision

Malawi, known as "the warm heart of Africa", is a developing Sub-Saharan African country of 18 million people, suffering from lack of healthcare professionals, structured educational programs, and proper testing equipments to diagnose and treat various heart diseases.

Since 2013, MTIMA is helping to develop a structured cardiology program within medical institutions. We've brought over 50 medical volunteers to train more than 200 Malawian physicians, medical students and radiographers in educating cardiology didactics and training echocardiographic skills.

MTIMA is currently working with local partners in clinical and academic institutions in Malawi to develop and design an effective medical education programs. We bring comprehensive cardiology education and innovative diagnostic technology to the most vulnerable communities.

How We Serve


We provide various ways to support our partners with medical education, equipment donation, telemedicine and charities for the programs to flourish, so we can grow together.


We take time with our local partners to optimally strategize the institution's goal to achieve success in medical education and training in diagnostic imaging program.


We help to archive and manage diagnostic images securely with innovative technology, so that practitioners can learn and provide best practice with confidence.


We help to host engaging and meaningful medical education events, so that our partners can have the most enhanced learning experience.


We provide healthcare practitioners with didactic and hands-on echocardiographic training to obtain  optimal diagnostic images for  important clinical decisions.


We are there to provide on-site and virtual cardiology consultation, on clinical results and diagnostic images, and we develop into educational materials for future use.
