Eight patients with severe symptomatic calcific aortic stenosis were considered to be unsuitable for valve replacement. Four were admitted with pulmonary oedema and three in cardiogenic shock and one had angina at rest. With the use of echocardiographic and radiographic guidance percutaneous transluminal aortic valvuloplasty was carried out. Aortic gradients were reduced by an average of 40%. All four patients who presented with cardiac failure improved immediately and remained well six months later. The patient with angina was symptom free at nine months. Two of the three patients who presented in cardiogenic shock improved immediately and were well nine and three months later. The other patient died four hours after the procedure. Doppler echocardiographic studies showed a slight initial increase in aortic incompetence, but this did not worsen and valvar gradients remained improved three and six months later. Percutaneous valvuloplasty of the aortic valve is an effective therapeutic option in patients with severe calcific aortic stenosis who are unfit for surgery. Its role as an alternative to surgery has not been considered and should be investigated in a controlled clinical trial.
8例有严重症状的钙化性主动脉瓣狭窄患者被认为不适合进行瓣膜置换。4例因肺水肿入院,3例处于心源性休克,1例有静息性心绞痛。在超声心动图和放射学引导下进行了经皮腔内主动脉瓣成形术。主动脉压差平均降低了40%。所有4例出现心力衰竭的患者立即好转,6个月后仍状况良好。有静息性心绞痛的患者9个月时无症状。3例心源性休克患者中有2例立即好转,分别在9个月和3个月后状况良好。另1例患者在术后4小时死亡。多普勒超声心动图研究显示最初主动脉瓣关闭不全略有增加,但未加重,3个月和6个月后瓣膜压差仍保持改善。对于不适合手术的严重钙化性主动脉瓣狭窄患者,经皮主动脉瓣成形术是一种有效的治疗选择。其作为手术替代方案的作用尚未得到考虑,应在对照临床试验中进行研究。
