Abstract

Einleitung: Die Ursachen aneurysmatischer Erweiterungen der Aorta sind vielseitig und bis heute nicht bis ins letzte Detail bekannt. Ein seltener, aber klinisch gut belegter Zusammenhang findet sich zwischen der Infektion mit Treponema pallidum und dem luetischen Aortenaneurysma.

Abstract

OBJECTIVES An ascending aortic aneurysm with aortic valve regurgitation (AR) may be treated by sinutubular junction remodelling (STJR) with aortic cusp repair if the root diameter is preserved. We analysed the outcome of STJR with cusp repair. METHODS Between 1995 and 2010, 1094 patients underwent valve-preserving surgery. Of these, 560 individuals with root replacement, 128 patients with acute aortic dissection and 262 patients with preoperative AR ≤ II were excluded. The remaining 144 patients (mean age 56.0 ± 17.0 years, 103 males) underwent STJR ± cusp repair for ascending aortic aneurysm and AR ≥ III. In all, sinus dimensions were preserved according to the following criteria: maximum diameter ≤42 mm in bicuspid aortic valve (BAV, n = 59) and unicuspid aortic valve (UAV, n = 27), and ≤45 mm in tricuspid aortic valves (TAV, n = 58). In BAV, right–left (n = 52) and right-non-coronary (n = 7) cusp fusions were seen. To evaluate the influence of valve morphology, patients were divided into two groups: TAV and non-TAV. The patients with non-TAV were younger (P < 0.01) and had less concomitant cardiac surgery (P < 0.01). The mean follow-up was 25.9 ± 22.0 months. RESULTS Early mortality was 2.1% (n = 3). The causes of death were cardiac (n = 1), respiratory (n = 1) and mesenteric ischaemia (n = 1). Higher age was the predictor of early mortality by multivariate analysis (P = 0.04, hazard ratio 13.2). Overall 5-year survival was 93.9 ± 2.9% (TAV, 82.8 ± 10.2%; non-TAV, 98.5 ± 1.5%; P = 0.02). Causes of late death were cardiac (n = 1), respiratory (n = 1) and carcinoma (n = 1). Freedom from recurrent AR ≥ III at 5 years was 80.1 ± 7.7% (TAV, 97.0 ± 3.0%; non-TAV, 73.4 ± 8.7%; P = 0.02). By multivariate analysis, only aortoventricular junction (AVJ) > 28 mm (P < 0.01, hazard ratio 9.7) was a predictor of recurrent AR. Freedom from reoperation at 5 years was 81.9 ± 7.8% (TAV, 97.0 ± 3.0%; non-TAV, 76.6 ± 8.8%; P < 0.05). The causes of reoperation (five re-aortic valve repairs and four valve replacements) were dehiscence of pericardial patch (n = 7) and recurrent cusp prolapse (n = 2). By multivariate analysis, only AVJ > 28 mm was a significant predictor for reoperation (P < 0.01, hazard ratio 11.6). CONCLUSIONS STJR with cusp repair is a useful technique in patients with an ascending aortic aneurysm and relevant AR. Although the dilated AVJ is a risk of recurrent AR and reoperation, concomitant cusp repair is associated with an acceptable mid-term outcome. [ABSTRACT FROM AUTHOR]
