Central Veno-Arterial Extracorporeal Membrane Oxygenation (C-VA-ECMO) After Cardiothoracic Surgery: A Single-Center Experience.
Central veno-arterial extracorporeal membrane oxygenation (C-VA-ECMO) provides temporary cardiorespiratory support for patients in heart failure who cannot be weaned from cardiopulmonary bypass successfully. Outcomes are influenced by the reversibility of the initial insult and complications of the technique. ⋯ Overall one-third of patients in the cohort who the authors believe would otherwise have died from postcardiotomy cardiogenic shock survived because C-VA-ECMO was commenced after cardiac surgery. Survival is greater in transplantation patients necessitating this form of support during or immediately after surgery.

Comparative Study Observational StudyA Comparison of the Strain and Tissue Doppler-Based Indices as Echocardiographic Correlates of the Left Ventricular Filling Pressures.
Diastolic strain and strain rate, combined with E (peak transmitral velocity), have been proposed as novel noninvasive predictors of left ventricle (LV) filling pressures, avoiding angulation errors inherent to tissue Doppler indices (TDI). The primary objective was to study the correlation of strain-based indices (SBI) and TDI with pulmonary artery catheter-derived LV end-diastolic pressures (LVEDP). The secondary aim was to determine appropriate cut-off of indices to predict LVEDP ≥15 mmHg. ⋯ SBI were better predictors of LVEDP, compared with TDI, in patients with preserved EF and indeterminate E/e' values.
