Simultaneous transapical transcatheter aortic valve replacement and transcatheter mitral valve replacement for native valvular stenosis.

Transcatheter aortic valve replacement (TAVR) is well established for patients who cannot undergo surgery (Leon et al., N Engl J Med 2010;363:1597) or are high risk for surgery (Smith et al., N Engl J Med 2011;364:2187-2198). Experience with the TAVR procedure has led to recent reports of successful transcatheter mitral valve replacement (TMVR) procedures (Cheung et al., J Am Coll Cardiol 2014;64:1814; Seiffert et al., J Am Coll Cardiol Interv 2012;5:341-349) separately or simultaneously with the TAVR. However, these reports were of simultaneous valve-in-valve procedures (Cheung Anson, et al. J Am Coll Cardiol 2013;61:1759-1766). A recent report from Portugal also reported simultaneous transpical implantation of an inverted transcatheter aortic valve-in-ring in the mitral position and transcatheter aortic valve (Hasan et al., Circulation 2013;128:e74-e76). There has been an experience of TMVR only in native mitral valve for mitral valve stenosis, but none in both aortic and mitral valves. We report the first in human case of simultaneous transapical TAVR and TMVR in native valves secondary to valvular stenosis. Our patient was not a candidate for percutaneous balloon mitral valvuloplasty secondary to a high Wilkins Score. Sizing of the aortic valve was based on the transesophageal echocardiogram (TEE), whereas sizing of the mitral valve was based on TEE measurements and balloon inflation during left ventriculography. © 2015 Wiley Periodicals, Inc.

Impella RP Use in Refractory Cardiogenic Shock in a Patient Presenting With Acute Right Coronary Artery Occlusion: A Case Report.

It is common for patients with inferior myocardial infarction to experience right ventricular infarction, occurring in half of the patients with inferior myocardial infarction. Right ventricular failure due to acute right myocardial infarction is often associated with a worse prognosis. In this case, we report a patient with acute chest pain due to acute right coronary artery occlusion status post placement of multiple stents in the right coronary artery. Unfortunately, he developed refractory cardiogenic shock requiring biventricular assist device placement.

Prosthetic Aortic Valve Endocarditis Creeping Into the Paravalvular Space.

Prosthetic valve endocarditis is a devastating infection with a challenging diagnosis and management. Despite advances in its diagnostic modalities, medical, and surgical interventions, prosthetic valve endocarditis still carries high morbidity and mortality rates. Here, we report a case of prosthetic aortic valve endocarditis that progressed to involve the paravalvular space and the importance of multimodality cardiac imaging in the early detection of paravalvular complications.
