Predictors of Left Ventricular Outflow Tract Obstruction After Transcatheter Mitral Valve Replacement.

Objectives: The aim of this study was to evaluate the predictors of left ventricular outflow tract (LVOT) obstruction after transcatheter mitral valve replacement (TMVR).

Background: LVOT obstruction is a major concern with TMVR, but limited data exist regarding its predictors and impact on outcomes.

Methods: Patients with pre-procedural multidetector row computed tomography (MDCT) undergoing TMVR for failed mitral bioprosthetic valves (valve-in-valve), annuloplasty rings (valve-in-ring), and mitral annular calcification (valve-in-MAC) were included in this study.

Intracardiac embolization of inferior vena cava filter associated with right atrium perforation and cardiac tamponade.

Insertion of inferior vena cava filters has been well established in literature, reducing occurrence of pulmonary embolism after an episode of deep venous thrombosis in patients with contraindication to anticoagulation. There are a small number of complications related to procedure and embolization is rare. In this context, we described a case of intracardiac embolization associated with cardiac tamponade.
