“…With an average logistic Euroscore (aleS) of 4.1 the overall 30-day mortality for CABG is 1.8%, for patients presenting with acute MI during the first 6 days average operative mortality is 5.7% (aleS 8.9). In isolated aortic valve surgery operative mortalities during the late 1980s and early 1990s were around 5% [13]. Today, in our department the chance to die during the first 30 days after aortic valve replacement is 1.7% (aleS 7.0), if an additional CABG is performed, 30-day mortality is 2.4% (aleS 8.7).…”

“…In CABG, the average age of a patient at the time of operation during the early 1990s was 61 years [12] valve patient in the early 1980s was between 55 [13] and 65 [14], the average biological aortic valve patient was 72 [14]. Today's average age of aortic valve patients in our department is 72, if they receive an additional CABG they are 76 years old.…”

“…Today's average age of aortic valve patients in our department is 72, if they receive an additional CABG they are 76 years old. In mitral surgery, patients were between 53 [13] and 61 years [15]. Today the average patient in our department who needs isolated mitral valve repair or replacement is 65, if they need additional CABG they are 71 years old.…”

“…In patients with regular left ventricular function aortic valve replacement is a safe operation with an operative risk of about 2-8% [4,5] and strongly recommended in these patients [6]. Risk factors for an increased operative risk and for late death include high NYHA class, impaired left ventricular function, age and presence of associated aortic regurgitation, coronary artery disease or preoperative ventricular arrhythmias [7].…”

Zusammenfassung. Grundlagen: Fü r Patienten mit Aortenklappenstenose (AKS) ist der Grad der präoperativen Auswurffraktion entscheidend fü r das postoperative Langzeitergebnis. Zweck dieser Untersuchung war es die genetischen Veränderungen während der Progression der Herzinsuffizienz zu beschreiben.Methodik: Die totale RNA von Myokardbiopsien von Patienten mit normaler (>60 %) oder reduzierter (<30 %) Pumpfunktion sowie signifikanter linksventrikulärer Hypertrophie im Rahmen ihrer AKS wurden mit dem Affymetrix HG-U133A und U133B GeneChip untersucht.Ergebnisse: Obwohl es zu einer massiven Verände-rung des Transkriptoms durch die linksventrikuläre Hypertrophie kommt, sind die Veränderungen im Rahmen der Progression der Herzinsuffizienz gering.Schlussfolgerungen: Selektive myokardiale Gentranskripte wie beispielsweise Fibrillin 1 oder Versican stellen interessante Kandidaten fü r mögliche Marker dar, welche die Progression der Herzinsuffizienz beschreiben könnten.

Pivoting system fracture in a bileaflet mechanical valve: A case report

et al. 2009

View full text Add to dashboard Cite

A leaflet escape occurred in a low profile bileaflet mechanical prosthesis manufactured by TRI-Technologies that had been implanted for 3 years in the mitral position of a 32 year old patient. The escaped leaflet had embolized and was subsequently located by an abdominal computerized axial tomography scan and ultrasound in the terminal portion of the aortic bifurcation. The embolized leaflet was removed 3 months after valve replacement surgery. In an attempt to determine the cause of the escape the retrieved embolized leaflet was investigated. Techniques employed included visual examination aided by stereo-microscopy, x-ray imaging and scanning electron microscopy. One of the ears had fractured and was missing from the leaflet. Chipping was observed at the leaflet ear position on both the inflow and outflow surfaces. Visual and SEM observations found fractographic river-lines that indicated an apparent origin at the inflow surface of the ear nearest to the straight 'B-datum' line or coaptation edge. The origin seemed to be in the radius between the leaflet ear and the leaflet body. SEM observation of the remaining intact ear showed wear marks on both the inflow and outflow sides of the leaflet ear that corresponded to the suspected origin of fracture. It is believed that the use of boron alloyed pyrolytic carbon material and the leaflet's homogeneous monolithic structural design were factors that contributed to this adverse event.

Long-term results of heart valve replacement with the Edwards Duromedics bileaflet prosthesis: A prospective ten-year clinical follow-up

Abstract: These results confirm that the Edwards Duromedics valve shows excellent performance concerning thromboembolism, hemolysis, and functional improvement and will serve as a reference for the last version, the Edwards Tekna valve, where comparable long-term data are currently not available.
