One of the benefits of mobile devices, such as the iPad and iPhone, is the ability to access important clinical information at the point of care. One of these apps is CathSource which has been developed as an authoritative mobile resource on cardiac catheterisation.

This important intervention is regularly used to diagnose and treat a wide range of cardiac conditions.

The CathSource app, developed by Drs. Bilhartz and Mahjoobi (cardiologists from Texas A&M) of ECGsource LLC and sponsored by Scott & White Healthcare, aims to assist healthcare professionals in the understanding and recognition of cardiac pathology via cardiac catheterization multimedia.

iMedicalApps has reviewed the iPhone version of CathSource previously.

When we reviewed CathSource for the iPhone, we concluded

  • “The CathSource app represents a worthwhile purchase for residents or medical students interested in cardiology, as it uses catheterization films and associated figures to help depict and discuss cardiac pathology as seen via cardiac catheterization.
  • The app could potentially be useful for patient education as well, due to the plethora of cardiac cath videos and pictures — helping patients get an in-depth understanding of their upcoming procedure.”

The first point to note is that the transition to iPad has not harmed the app in any way. There is still a huge range of information contained within the app and the quality and content has not changed.

The addition of the extra screen space from the iPad means that it is possible to fit more information on the page as shown to great use in the screenshot below.

The next major improvement is the fact that videos of angiograms and aortagrams etc. all play full screen. This means that it is easier to see and make out abnormalities and also increases the chances that this app could be used for patient education purposes. The impressive range of cardiac conditions contained in this app mean that many trainees and medical students will find this app useful in terms of their general education while Cardiology trainees will find that this app is an essential mobile resource containing large amounts of relevant clinical information.

One of the good points of this app is the inclusion of references at the end of each article which reassures users about the validity of the information. Similarly, another useful feature is the ability to view the complete range of images in full screen, although, one potential improvement would be to allow this to take place in the middle of an article.

Perhaps one of the few improvements of this app would be to include a way to export or share articles with colleagues.


  • $3.99


  • Large range of cardiac conditions included
  • Good user interface and use of extra screen size
  • Detailed range of information
  • References at the end of each article


  • Not all images can be enlarged to full screen when found in the topic

Healthcare providers that would benefit from the app

  • Interventional radiologists and trainees
  • Internal medicine trainees (Physician residents) and medical students


  • CathSource is a fantastic app not just limited to cardiology trainees (Cardiology Fellows and Resident Physicians). The range of information contained will be useful for trainees and medical students at all levels. The use of the iPad increases the utility as the extra screen space highlights the key content and makes images and videos easier to view.
