Whispers of the Cath lab: "Cases we would rather forget".

ABSTRACT

In the dynamic field of interventional cardiology, significant strides have been made in reducing periprocedural complications. Echocardiography, particularly transesophageal echocardiography, plays a key role in ensuring the safety and success of structural heart interventions. Its real-time imaging capabilities allow for precise monitoring of device positioning, deployment, and procedural outcomes. By adhering to established imaging protocols and acquiring standard imaging planes, periprocedural echocardiography has become an essential tool for the successful performance of many structural heart interventions. In this manuscript, we present a series of unusual yet significant complications that we encountered during structural interventional procedures in our catheter laboratory. These complications, detected through echocardiography, underscore the critical role of imaging guidance in recognizing, and addressing unforeseen challenges, such as device malposition, thrombus formation in cardiac chambers during structural heart interventions, and cardiac tamponade during transcatheter mitral valve procedures. Through these cases, we highlight the effectiveness of transesophageal echocardiography in promptly identifying complications, allowing for timely intervention and resolution.
