A succinct update relevant to all arrhythmia and heart failure surgeons. The concept of atrial cardiomyopathy is particularly stimulating.

The authors report on an echocardiographic sub-study of the NOTION trial, a prospective randomized study which compared outcomes between 120 patients undergoing TAVI and 112 patients undergoing aortic valve replacement (AVR).

The authors report on their findings an ongoing Japanese multicentre prospective registry. They evaluate outcomes in 478 patients undergoing transfemoral  TAVI and treated with percutaneous puncture using an expandable sheath, Edwards Sapien XTprosthesis and a Perclose ProGlide system.

This analysis of PARTNER data evaluated the impact of chronic kidney disease (CKD) on outcomes after TAVR.  Patients were grouped according to GFR as none/mild, moderate, and severe renal disease.  Severe disease was most common among women with diabetes.

The authors describe their findings in a multicenter retrospective review of clinical outcomes in 64 patients with severe mitral annular calcification considered poor candidates for traditional surgical mitral valve replacement, undergoing transcatheter mitral valve implantation with a balloon expandable prosthesis.

This article explores the controversial topic of TAVR versus surgical AVR in low-risk patients.  The primary outcome was 3-year survival.  The authors report 3-year survival for TAVR and surgical AVR as 72% and 83.4%, respective (p=0.0015).  Although TAVR is an exciting technology, there should be caution in adopting it in lower risk patients.

This article investigates the effects of varying degrees of aortic regurgitation (AR) on survival after transcatheter aortic valve replacement (TAVR).  They retrospectively evaluated a cohort of 237 patients undergoing TAVR from 2006 to 2012 with echocardiogram performed within 30 days of the procedure.  Using a Cox proportional multivariable regress

In medicine we often use words not understandable to patients. For example, instead of saying, "does it hurt when you pee,” we say, “dysuria”… Roughly 80% of patients don’t understand their medical condition (Am J Emerg Med. 2000; PMID 11103725).  This cartoon animation provides a clear explanation to help patients understand aortic stenosis.
