Abstract

Objectives

To evaluate the impact of the angles quantified by multidetector computed tomography (MDCT) between the ascending aorta’s long axis and, the left ventricular inflow long axis (LVLA), or the left ventricule outflow tract long axis, and the occurrence of post-transcatheter aortic valve replacement (TAVR) aortic regurgitation (AR).

Methods

We prospectively included 136 consecutive patients who underwent a transfemoral TAVR with a preoperative MDCT. The groups were defined according to AR <2 or ≥2 assessed by echocardiography at 1 month.

Results

AR ≥2 identified in 21 patients (15.4%), was associated with increased rates of mortality (p value 0.02) and heart failure (p value 0.001) at 1-year follow-up. The aorta–LVLA angle was significantly higher in patients with AR ≥2 (130.5° ± 8.8° vs. 124.6° ± 9.5°; p = 0.009). On univariate analysis, aorta–LVLA angle was predictive of AR ≥2 [OR 1.07 per degree (1.02–1.13); p = 0.011]. After adjustment on annular calcification extent, the percentage of prosthesis-annular mismatch and the type of prosthesis, the relationship between aorta–LVLA angle and the risk of AR ≥2 remained unchanged.

Conclusions

We showed that increased angulation between the ascending aorta and the LVLA is associated with higher rates of AR post-TAVR independent of other potential correlates.

Dank Nasenspray seltener in die Notaufnahme

Durch die intranasale Applikation von Etripamil lassen sich paroxysmale supraventrikuläre Tachykardien (PSVT) oft in Eigenregie beenden. Das erspart den Betroffenen das Aufsuchen von Notfallambulanzen.

Vorhofflimmern: So häufig kommt es bei Katheterablation zu Embolien

Arterielle Embolien – insbesondere Hirnembolien - sind eine mögliche periprozedurale Komplikation bei Katheterablation von Vorhofflimmern. Wie hoch ist das Risiko? Eine Analyse von weltweit mehr als 300.000 Ablationsprozeduren gibt darüber Auskunft.

Extrakorporale Reanimation: Wechsel des EKG-Musters verschlechtert Prognose

Patientinnen und Patienten im Herzstillstand mit schockbarem Rhythmus, deren EKG-Muster sich später ändert, haben schlechtere Chancen. Eine Studiengruppe hat die Bedeutung eines solchen Rhythmuswechsels mit Blick auf die extrakorporale Reanimation genauer untersucht.

Leben retten dank Erste-Hilfe-App

Bei einem Herzstillstand zählt jede Minute bis eine Reanimation begonnen wird. Notfallmediziner Prof. Dr. med. Michael Müller erklärt im Interview, wie medizinisch geschulte Ersthelfende mittels App alarmiert werden können – und warum digitale Lösungen die Notfallversorgung revolutionieren könnten.
