ABSTRACT
BACKGROUND:
Mitral- and tricuspid regurgitation are associated with significant morbidity and mortality and are increasingly treated interventionally. CardioMEMS is a transcutaneously implanted pressure sensor placed in the pulmonary artery that allows invasive measurement of pulmonary artery pressure and cardiac output.METHODS:
This proof-of-concept study aimed to observe hemodynamic changes as determined by CardioMEMS after transcatheter atrioventricular valve interventions, assess the additional value of CardioMEMS on top of echocardiography, and investigate a potential effect of CardioMEMS on outcome. Patients treated with transcatheter mitral- or tricuspid valve interventions (mitral TMVR, tricuspid TTVR) or bicaval valve implantation (bi-CAVI) were recruited. All patients were followed for 12 months.RESULTS:
Thirty-six patients were included (4 with CardioMEMS, 32 controls). Patients with CardioMEMS were monitored prior to intervention and 3-12 months thereafter (one received TMVR, one bi-CAVI, one both TMVR and TTVR, and one isolated TTVR). CardioMEMS group In both patients with TMVR and in the patient with bi-CAVI, mean pulmonary artery pressures decreased (all p < .001) and cardiac output increased significantly (both TMVR p < .001 and bi-CAVI p = .006) while functional parameters, echocardiography, and NT-proBNP were difficult to interpret, unreliable, or both. Changes after TTVR remained inconclusive.CONCLUSION:
Invasive monitoring using CardioMEMS provides important information after mitral- and tricuspid valve interventions. Such data pave the way for a deeper understanding of the prerequisites for optimal patient selection and management for catheter-based interventions.Palabras clave
