This website aims to develop an international portal for
learning the complex and dynamic morphology of the congenitally malformed heart through discussion and interaction. The main focus is on the clinical appliaction of advanced cardiac imaging in the assessment of cardiac morphology and function.
Three dimensional echocardiography: (3DE, sometimes also referred to as 4DE fourth Dimension being time) is a unique method of visualizing the true and dynamic morphology of the heart. The technique is not just a way of displaying moving images of the heart in 3D. 3DE incorporates a core of biometric data set frozen in time. This enables the cardiologist to bring the frozen heart to life and to dissect it, time and time again.enabling comparison between pre and postoperative anatomy and learn from mistakes. It is also possible to share the data electronically between professionals. With the availability of netbased data sharing sites like Dropbox, Google Drive, Yousenditetc. it is now possible to receive and report large number of patients from different countries and institutions.
MPR: The most important aspect of 3dimensional echocardiography is the potential to slice the dynamic cardiac structures in infinite planes through the three dimensions similar to a cardiac pathologist dissecting the heart to reveal underlying pathology. This method of analysing the anatomy is termed Multiplanar Reformating or Multiplane Review (MPR). I improvised this technique by moving the planes of dissection, in anatomically appropriate planes throughout the cardiac cycle to define accurately the underlying pathology from which the 3D morphology is reconstructed. This technique is most useful in assessing complex congenital heart defects. It is also helpful to understand the anatomy when resolution of the images are poor and a visually useful 3D image cannot be reconstructed. It marks a transitional phase between 2D and 3D imging within the restrictions of current image resolution.
Take some time to explore
the website. Individual heart defects are discussed under heart defects. These chapters are being rewritten and please revisit the site if you have not visited recently. For further details of the techinques please also refer to the recent publication in Heart. Do feel free to contact if you have any comments, questions or would like to send any images for assessment/discussion.
The above Video is from a 35 year old lady who had an attempted closure of the PFO which lead to the device embolization. A 14mm Amplatzer ASD device was initially used for the attempted closure.
The device embolized in to the Aorta next day. This was sucessfully retrieved and the above 3D pictures were taken at the time of retrieval and implantation of a 35mm PFO device.
