Die Auskultation ergab ein systolisches Herzger\u00e4usch Grad IV\/VI mit einem rechtsseitigen Punctum maximum. Radiologisch fanden sich Hinweise auf eine Linksherzvergr\u00f6\u00dferung. Das EKG in rechter Seitenlage des Tieres zeigte eine Sinustachykardie mit einer Frequenz von 360 Schl\u00e4gen\/Minute. Echokardiographisch wurden unauff\u00e4llige Dimensionen der Kammern und Vorkammern festgestellt. Bei der zweidimensionalen Darstellung lie\u00df sich ein perimembran\u00f6ser Ventrikelseptumdefekt (ca. 0,8 mm im Durchmesser) nachweisen, der sowohl von rechts (L\u00e4ngs- und Kurzachse) als auch von links parasternal darstellbar war. Bei der Doppler- Echokardiographie pr\u00e4sentierte sich dieser als reiner Links-rechts- Shunt mit einer systolischen Maximalflussgeschwindigkeit von 5,2 m\/s. Zudem bestand eine relative Pulmonalstenose (Flussgeschwindigkeit Arteria pulmonalis: 1,02 m\/s im PW-Doppler). Aufgrund dieser Befunde wurde der Defekt als restriktiver Ventrikelseptumdefekt einstuft. Eine medikament\u00f6se Therapie war zu diesem Zeitpunkt nicht erforderlich. Eine Nachuntersuchung nach 7 Wochen zeigte eine unver\u00e4nderte morphologische und h\u00e4modynamische Situation. Das Tier verstarb ca. 6 Jahre sp\u00e4ter an einer nichtkardialen Ursache. Der Ventrikelseptumdefekt bei diesem Zwergkaninchen stellte sich damit sowohl klinisch als auch sonographisch vergleichbar zu entsprechenden Befunden bei Hund und Katze sowie bei einem Kaninchen der Rasse Wei\u00dfer Neuseel\u00e4nder dar.<\/jats:p>","DOI":"10.15654\/tpk-150208","type":"journal-article","created":{"date-parts":[[2016,1,14]],"date-time":"2016-01-14T17:32:11Z","timestamp":1452792731000},"page":"59-64","source":"Crossref","is-referenced-by-count":3,"title":["Restriktiver Ventrikelseptumdefekt bei einem Zwergkaninchen"],"prefix":"10.15654","volume":"44","author":[{"given":"C.","family":"Leuser","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Miltz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Henrich","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Schneider","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Hildebrandt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2017,12,18]]},"reference":[{"key":"10.15654\/TPK-150208-1","unstructured":"Bonagura JD, Lehmkuhl LB.
