Current devices are focused primarily on bicaval implantation. The outcomes for patients with (inferior vena cava) IVC implantation only are less clear.

The average age of patients was 78.8\u2009\u00b1\u20096.7 years. Most patients had NYHA class III\/IV heart failure symptoms (78.8%). The average overall Kansas City Cardiomyopathy Questionnaire (KCCQ\u2010OS) score at baseline was 36.9\u2009\u00b1\u200922.8. Successful device delivery occurred in 9\/10 of patients. Post\u2010implant, there was an increase in right atrial (RA) pressure that returned to baseline at 6 months. Hepatic vein diameter decreased from (13.1\u2009+\u20093.1\u2009mm at baseline to 8.7\u2009+\u20093.0\u2009mm at 12 months). Six patients survived to 12 months. Of those patients, all had NYHA Class I\/II symptoms. Of patients completing follow\u2010up, KCCQ\u2010OS scores increased by 43.4 points at 1\u2010year. Computer tomography revealed asymptomatic stent fractures in 7 patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Caval valve implantation with the Edwards Caval Prestent system in the IVC only was feasible and safe in patients with severe TR. Patients exhibited a decrease in hepatic vein diameter. There were significant improvements in KCCQ\u2010OS scores beginning at 30 days that continued out to 1 year. Future design iterations are needed to address stent fractures.<\/jats:p>\n
