“…In one study of MDCT analysis of the LCx relation to the mitral annulus, the proximal LCx can be remarkably close to mitral annulus in mid systole. Another study suggests that LCx place can be used as a marker to locate the mitral annulus plane during the procedure, with distance of <5 mm between the two planes (83)(84)(85)(86)(87). In TMVR studies, there was no LCx injury or occlusion reported, and rather it seems a complication of transcatheter annuloplasty.…”

Mitral regurgitation is the most common valvular lesion in the developed world, with increasing prevalence, morbidity, and mortality. The experience with surgical mitral valve repair or replacement is very well-validated. However, more than 45% of these patients get denied surgery due to an elevated risk profile and advanced disease of the left ventricle at the time of presentation, promoting the need for less invasive transcatheter options such as transcatheter repair and transcatheter mitral valve replacement (TMVR). Early available TMVR studies have shown promising results, and several dedicated devices are under clinical evaluation. However, TMVR is still in the early developmental stages and is associated with a non-negligible risk of periprocedural and post-procedural complications. In this review, we discuss the current challenges facing TMVR and the potential TMVR-related complications, offering an overview on the measures implemented to mitigate these complications, and future implications.

“…Lifelike, 4DCT cinematic rendering may be more useful compared to traditional 3D volumetric reconstructions. CT is indispensable for mitral annulus sizing and for the prediction and evaluation of LVOT obstruction risk in TMVR ( Figure 3, Video 2) (10,(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22). Additionally, CT allows precise measurement of the geometric mitral valve area, predicts optimal fluoroscopic angles and identifies the location of the coronary sinus in relation with the annulus (Figure 4).…”

As minimally invasive cardiovascular procedures gain popularity, novel transcatheter mitral valve repair devices continue to emerge. The success of these technologies is critically dependent on high quality imaging performed at all stages: patient selection, intervention planning, intraprocedural guidance, monitoring complications and follow-up. We present an overview of specific imaging requirements and challenges applicable to mitral valve interventional techniques. Modern valve imaging is multimodal and primarily combines echocardiography and computed tomography (CT). Echocardiography remains the gold standard for detailed anatomic imaging, complete hemodynamic characterization and real-time guidance and evaluation of procedural success. CT is indispensable for mitral annulus (MA) imaging and in predicting left ventricular outflow tract (LVOT) obstruction post transcutaneous mitral valve replacement (TMVR). 3D modeling, fusion imaging and automated image analysis may further contribute to the evolutionary transformation of valvular heart imaging.

Transcatheter interventions to treat mitral and tricuspid valve disease are becoming increasingly available because of the growing number of elderly patients with significant comorbidities or high operative risk. Thorough clinical and imaging evaluation in these patients is essential. The latter involves both characterization of the mechanism and severity of valvular disease as well as determining the hemodynamic consequences and extent of ventricular remodeling, which is an important predictor of future outcomes. Moreover, an assessment of the suitability and risk of complications associated with device-specific therapies is also an important component of the preprocedural evaluation in this cohort. Although echocardiography including 2-dimensional and 3-dimensional methods has an important role in the initial assessment and procedural guidance, cross-sectional imaging, including both computed tomographic imagning and cardiac magnetic resonance imaging, is increasingly being integrated into the evaluation of mitral and tricuspid valve disease. In this review, we discuss the role of cross-sectional imaging in mitral and tricuspid valve disease, primarily valvular regurgitation assessment, with an emphasis on the preprocedural evaluation and implications for transcatheter interventions.
