RESUMO
Background: Aortic valve stenosis (AS) is the most common valvular disease. Its surgical indication is undisputed in symptomatic severe AS, however, 30% of patients are at high surgical risk or inoperable. Transcatheter Valve Implantation (TAVI) is an alternative for this group of patients. Aim: To describe the clinical outcomes of TAVI in a group of patients treated at the Instituto Nacional del Tórax, Santiago, Chile. Patients and Methods: Prospective study including all patients referred for TAVI due to their high surgical risk or being inoperable. All-cause mortality, secondary stroke, permanent pacemaker implantation, vascular complications, prosthetic and periprosthetic regurgitation, Karnosfky test and Functional Capacity (FC) were assessed as endpoints. Results: We evaluated 26 patients with a mean age of 82 years (74% women) in whom 27 procedures were done. The mean Society of Thoracic Surgeons score was 8.8%. Overall mortality at 30 days, one and two years was 11.1, 18.5 and 29.6% respectively. Karnofsky score increased significantly from 62.3% at baseline to 83.9; 88.6 and 88.8% at six months, one and two years, respectively. Prior to the procedure, FC was 3.1 ± 0.6, decreasing significantly to 1.2; 1.3 and 1 at six months, one and two years of follow up. Conclusions: TAVI is an effective alternative treatment for patients with severe symptomatic AS and high surgical risk.

Se presenta el caso clínico de una mujer de 20 años que presenta insuficiencia cardíaca de rápida instalación, asociada a síntomas de infección respiratoria viral, 9 semanas post parto. Previamente había presentado hipertensión en el puerperio precoz. Se demostró una severa disfunción sistólica (FE 12 por ciento). Se recuperó con medidas convencionales del tratamiento de Insuficiencia cardíaca y finalmente recibió bromocriptina basado en reportes favorables de la literatura respecto del uso de este fármaco. En el control al año de su alta, se mantenía asintomática pero persistía severa disminución de la FE (18 por ciento) y dilatación de cavidades izquierdas. Se revisa la información acerca de esta patología.
A 20 year old woman developed rapidly progressive heart failure 9 weeks after delivery. For a few weeks she was hypertensive. A severe systolic dysfunction with an EF of 12 percent was shown on echocardiography. She recovered on conventional treatment of congestive heart failure. Eventually she received bromocriptine con the basis of favorable literature reports. A follow up control at one year showed an asymptomatic patient, however severe systolic dysfunction with EF 18 percent was still present.
