Teleconsultation of coronary angiograms using smartphones and an audio/video conferencing application.
OBJECTIVE
To examine the feasibility and accuracy of teleconsultation of coronary angiograms using iPhone 4 and FaceTime.


METHODS
The study was conducted in two stages. Coronary angiograms of 100 patients with single-vessel disease were retrospectively selected by a core laboratory unit and then re-evaluated by a consultant cardiologist on both an iPhone 4 screen via the FaceTime application and on the workstation monitor of the angiography laboratory. The interpretations of the consultant cardiologist on localization and severity of angiographic lesions were recorded and compared with those of the core laboratory. Using the same teleconsultation system, the consultant cardiologist outside the hospital was presented live angiographic images of 10 patients undergoing primary percutaneous coronary intervention (PCI) for acute myocardial infarction.


RESULTS
Interpretations of the consultant cardiologist on the localization and severity of 100 lesions on both the smartphone screen and workstation monitor showed high levels of agreement with the results of the core laboratory (for all, κ > 0.80). Of 10 patients whose PCI was performed under live video teleconsultation, eight patients underwent successful PCI while two patients had normal coronary arteries. There was an excellent agreement between the consultant cardiologist and the operator regarding lesion localization.


CONCLUSIONS
Smartphones allow highly accurate interpretations on angiographic lesions and thus may serve as a supplementary teleconsultation tool in both elective and emergency situations.
