However, ventricular assist devices have problems related to biocompatibility, hemocompatibility, and thromboembolic events, especially in younger patients. The present study examined the hemodynamic effects of a direct cardiac compression device using circumferential artificial rubber muscles in a young swine model of dilated cardiomyopathy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Dilated cardiomyopathy was established in 6 pigs (\n                      <jats:xref ref-type=\"bibr\">6<\/jats:xref>\n                      <jats:xref ref-type=\"bibr\"\/>\n                      \u2013\n                      <jats:xref ref-type=\"bibr\">8<\/jats:xref>\n                      weeks of rapid right ventricular pacing; average weight, 22.6 \u00b1 2.1 kg). The device was designed using pneumatic rubber muscles (Fluidic Muscle, Festo). Hemodynamic parameters were monitored under baseline conditions, after the assistance, and after inducing ventricular fibrillation. Hemodynamic data were acquired using a PiCCO, multilumened thermodilution catheter in the pulmonary artery, left ventricular pressure monitoring, and epicardial echocardiography.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Direct epicardial assistance resulted in a significant improvement in hemodynamic data.
