Aortic stenosis is a congenital or acquired reduction in the area of the aortic valve, resulting in obstruction of the blood flow from the left ventricle to the aorta. Aortic stenosis accounts for 2-5% of all congenital heart defects and is a potentially life-threatening disorder. In adults aortic stenosis represents 34% of all valvular heart diseases. Degenerative etiology is present in 80% of cases. Patients with mild aortic stenosis are usually asymptomatic. Symptoms of the disease occur along with the disappearance of effective compensatory mechanisms. These are symptoms of low cardiac output syndrome manifested as fainting, dizziness, ischemic pains, exercise intolerance, arrhythmias with the risk of sudden cardiac death, and heart failure. As soon as the symptoms occur the prognosis significantly worsens, which is associated with a high risk of death. Percutaneous aortic valvuloplasty is a palliative method of treatment of aortic stenosis. The aim of the procedure is to relieve left ventricular outflow tract obstruction, thereby improving cardiac output. The etiology, course of the aortic stenosis and treatment methods, including invasive procedures, vary depending on the patients' age. The purpose of this paper is to present the characteristics of the aortic valve disease and the strategy of aortic balloon valvuloplasty in different age groups.
主动脉瓣狭窄是一种先天性或后天性的主动脉瓣面积减小,导致从左心室到主动脉的血流受阻。主动脉瓣狭窄占所有先天性心脏病的2% - 5%,是一种潜在的危及生命的疾病。在成人中,主动脉瓣狭窄占所有心脏瓣膜疾病的34%。80%的病例存在退行性病因。轻度主动脉瓣狭窄患者通常无症状。随着有效代偿机制的消失,疾病症状开始出现。这些是低心输出量综合征的症状,表现为晕厥、头晕、缺血性疼痛、运动不耐受、有心脏性猝死风险的心律失常以及心力衰竭。一旦症状出现,预后会显著恶化,这与高死亡风险相关。经皮主动脉瓣球囊成形术是治疗主动脉瓣狭窄的一种姑息性方法。该手术的目的是缓解左心室流出道梗阻,从而改善心输出量。主动脉瓣狭窄的病因、病程以及治疗方法,包括侵入性手术,因患者年龄而异。本文的目的是介绍不同年龄组主动脉瓣疾病的特点以及主动脉球囊瓣膜成形术的策略。
