Coarctation of the aorta is frequently associated with left ventricular inflow tract abnormalities that may be difficult to detect even at cardiac catheterization. This study involved patients with coarctation who underwent comprehensive two-dimensional echocardiographic investigations emphasizing visualization of the mitral valve and its apparatus. Of the 56 patients studied, 23 had completely normal study results, while in 33 (59%) results showed abnormalities of the mitral complex. The latter were divided into two groups: those having major mitral abnormalities (n = 12) and those with minor anomalies of the valve and apparatus (n = 21). The first group included patients with a supravalve stenosing ring, congenital mitral stenosis, mitral valve prolapse, and parachute mitral valve. Minor anomalies were classified as abnormalities of the papillary muscles, chordae tendineae, or combinations of both. No mitral malformations were found in a control group of patients. We conclude that two-dimensional echocardiography is a sensitive and accurate noninvasive method for assessing either significant or subtle forms of left ventricular inflow disease in patients with aortic coarctation. Its use is recommended for the acute medical and surgical management of these patients as well as for their long-term follow-up evaluation.
主动脉缩窄常伴有左心室流入道异常，即便在心脏导管检查时也可能难以发现。本研究纳入了接受全面二维超声心动图检查的主动脉缩窄患者，重点观察二尖瓣及其附属结构。在研究的56例患者中，23例检查结果完全正常，而33例（59%）结果显示二尖瓣复合体异常。后者分为两组：二尖瓣严重异常组（n = 12）和瓣膜及附属结构轻度异常组（n = 21）。第一组包括患有瓣上狭窄环、先天性二尖瓣狭窄、二尖瓣脱垂和降落伞样二尖瓣的患者。轻度异常被归类为乳头肌、腱索异常或两者皆有。在对照组患者中未发现二尖瓣畸形。我们得出结论，二维超声心动图是评估主动脉缩窄患者左心室流入道疾病的显著或细微形式的一种敏感且准确的非侵入性方法。建议将其用于这些患者的急性药物和手术治疗以及长期随访评估。
