The field of cardiology has grown rapidly over the last few decades. Though many cardiac procedures today could be addressed by catheter-based interventions, the quantum leap in technology and the development of newer echocardiography tools and machines have made a great impact and difference in precise diagnosis and treatment. Every cardiologist, physician, internist, and critical care specialist must be aware of the complete echocardiographic details. To facilitate that, we have compiled a series of case-based echocardiography write-ups and videos prepared by a group of experts in this area. All the case reports are unique with teaching points and show common problems with key messages for every reader.
