With the advent of transcatheter aortic valve implantation (TAVI), many AS patients, formerly considered inoperable, can receive effective treatment. The relief of the left ventricular pressure overload could lead, in some cases, to the occurrence of dynamic intracavity pressure gradients (DIG) with deleterious clinical impact. This phenomenon resembles the physiology seen in hypertrophic obstructive cardiomyopathy. We report a case in which alcohol septal ablation was used as a bail-out therapy for the acutely developed intracavity obstruction after TAVI. Potential dynamic intracavity gradients should always be excluded in the acutely deteriorated patient postoperatively. Alcohol septal ablation can be considered as a salvage therapeutic tool when other therapies are ineffective to treat subvalvular obstruction.
随着经导管主动脉瓣植入术(TAVI)的出现,许多以前被认为无法手术的主动脉瓣狭窄(AS)患者能够接受有效治疗。左心室压力超负荷的缓解在某些情况下可能导致动态心腔内压力梯度(DIG)的出现,产生有害的临床影响。这种现象类似于肥厚性梗阻性心肌病的生理表现。我们报告了一例病例,其中酒精室间隔消融术被用作TAVI后急性发生的心腔内梗阻的补救治疗。对于术后急性病情恶化的患者,应始终排除潜在的动态心腔内梯度。当其他治疗方法对治疗瓣下梗阻无效时,酒精室间隔消融术可被视为一种挽救性治疗手段。
