1 Restrictive Mitral Annuloplasty Does Not Limit Exercise Capacity
Marek A. Deja, MD, PhD, Aleksandra Żak, MD, Marcin Malinowski, MD, Piotr Pysz, MD, Ewa Gaszewska-Żurek, MD, Maciej Turski, MD, Piotr Janusiewicz, MD, Krystian Wita, MD, PhD, Jerzy Chudek, MD, PhD  The Annals of Thoracic Surgery  Volume 100, Issue 4, Pages (October 2015) DOI: /j.athoracsur Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Peak and mean mitral valve gradients measured with continuous wave (CW) Doppler on echocardiography at rest and on maximal exertion. (B) Peak and mean mitral valve gradients measured with pulse wave Doppler at the annular and leaflet tips level on echocardiography at rest and after the exertion. The gradients are presented as median with first and third quartiles together with the range of the values. The gradients before and after exercise were compared with the Wilcoxon signed rank test.

3 Fig 2 Relationship between (A) mean and (B) peak mitral valve (MV) gradient on exertion and indexed mitral ring geometric orifice area. Relationship between (C) maximal oxygen consumption (VO2) and (D) respiratory rate exchange ratio and ventilator equivalent for CO2 (VE/VCO2) slope on ergospirometry and indexed mitral ring geometric orifice area. The p and r values are from Spearman rank order correlation analysis. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 Correlation between resting norepinephrine level and oxygen consumption (VO2). The correlation coefficient (r) and p value are from the Spearman rank order correlation analysis.

5 Fig 4 Correlation between the respiratory rate exchange ratio and ventilator equivalent for CO2 (VE/VCO2) slope on ergospirometry and (A) left ventricular end-systolic volume index (LVESVI) and (B) left ventricular ejection fraction (LVEF). The correlation coefficient (r) and p value are from the Spearman rank order correlation analysis.
