• RHD is a rare cause of severe valvular AS. • Rheumatic MS typically accompanies rheumatic AV disease. • 2D and 3D echocardiography are essential in the assessment of rheumatic AS. • CCT has become crucial in planning therapeutic procedures for AS.

PURPOSE OF REVIEW/OBJECTIVE:Although rare, the development of mechanical complications following an acute myocardial infarction is associated with a high morbidity and mortality. Here, we review the clinical features, diagnostic strategy, and treatment options for each of the mechanical complications, with a focus on the role of echocardiography. RECENT FINDINGS/RESULTS:The growth of percutaneous structural interventions worldwide has given rise to new non-surgical options for management of mechanical complications. As such, select patients may benefit from a novel use of these established treatment methods. A thorough understanding of the two-dimensional, three-dimensional, color Doppler, and spectral Doppler findings for each mechanical complication is essential in recognizing major causes of hemodynamic decompensation after an acute myocardial infarction. Thereafter, echocardiography can aid in the selection and maintenance of mechanical circulatory support and potentially facilitate the use of a percutaneous intervention.

Secondary mitral regurgitation is one of the most common valve diseases. The disease is a result of left atrial or left ventricular dysfunction. It is generally classified into stages based on its severity. While surgical intervention does not confer improved survival in this subset of mitral disease, recent advances in transcatheter interventions have resulted in improved survival and symptomatology in carefully selected patients. In this review, the multimodality imaging evaluation of the mitral valve and secondary mitral regurgitation is discussed. Commercially available and investigational transcatheter interventions for secondary mitral regurgitation management are also reviewed.

Coronary artery obstruction caused by sinus sequestration is well described after transcatheter aortic valve implantation in failed bioprosthetic valves, which usually occurs during or shortly after the transcatheter aortic valve implantation procedure. We report the presentation, management, and outcomes of 2 cases of very late sinus sequestration in native aortic annuli, which has not been described before to our knowledge. (Level of Difficulty: Advanced.).

• Precise LAA anatomy must be established for LAA occlusion device selection. • We have developed the TUPLE maneuver, an acronym for “tilt up and turn left”. • The TUPLE maneuver facilitates LAA device selection and intraprocedural guidance.

• Paracardiac cysts (located adjacent to or inside the heart) are rarely detected. • There is a broad differential diagnosis for cysts encountered with echocardiography. • Multimodality imaging is crucial for comprehensively evaluating paracardiac cysts.
