Anamnese und klinischer Befund: Eine 73-jährige Frau stellte sich im Rahmen einer Routine-Evaluation bei vorbeschriebener hypertropher obstruktiver Kardiomyopathie (HOCM) vor. Als internistische Vorerkrankung bestand eine arterielle Hypertonie. Die Patientin klagte über eine progrediente Belastungsdyspnoe.
Untersuchungen: Echokardiographisch konnte ein im Verlauf der letzten 6 Monate rasch progredientes apikal gelegenes Vorderwandaneurysma dargestellt werden. In der kardialen Magnet-Resonanz-Tomographie (MRT) wurde in den aneurysmatischen Arealen eine Wanddicke von lediglich 2 mm gemessen.
Therapie und Verlauf: Aufgrund der raschen Größenzunahme des Aneurysmas in Verbindung mit der geringen Wanddicke und dem damit einhergehenden hohen Risiko einer Spontanruptur wurde die Patientin einer chirurgischen Therapie zugeführt. Intraoperativ bestätigten sich die zuvor nicht-invasiv erhobenen Befunde. Das Aneurysma wurde reseziert, der postoperative Verlauf war komplikationslos.
Folgerung: Aneurysmata der Herzspitze können in Folge einer HOCM entstehen. Bei rascher Größenprogredienz sollte eine Aneurysmektomie erfolgen.
History and admission findings: A 73-year-old patient presented for routine follow-up examination for pre-diagnosed hypertrophic obstructive cardiomyopathy (HOCM). The patientŽs history included arterial hypertension and dyspnea on exertion.
Interventions: Echocardiography revealed a large apical aneurysm, which had vastly increased in size over the past six months. Further evaluation by cardiac magnetic resonance (NMR) imaging confirmed the aneurysm and demonstrated a wall thickness of no more than 2 mm.
Treatment and course: Due to the rapid increase in size in addition to the extremely thin wall diameter the risk of spontaneous rupture was considered high and the patient was referred to surgical therapy. Echocardiographic and NMR-findings were confirmed intraoperatively. The aneurysm was resected and the postoperative progress was uneventful.
Conclusion: Aneurysms of the apical left ventricle can result from an underlying HOCM. In case of rapid increase of the aneurysm, aneurysmectomy should be performed.
