Left heart catheterization using the transbronchial route to obtain pressures in the left atrium and left ventricle was used successfully in 29 cases with no mortality or morbidity. It was found to be useful in differentiating between mitral stenosis and mitral insufficiency, as well as determining the amount of aortic stenosis present when there was involvement of the aortic valve. The technique was also helpful in determining which is the predominant lesion when there is a disease of the aortic and mitral valves. In two patients in a series of 29, data obtained by left heart catheterization forestalled operation on the basis of a mistaken diagnosis of mitral stenosis when actually no mitral valvular disease was present. In another eight patients, the predominant lesion was found to be mitral stenosis rather than mitral insufficiency as it was thought to be before catheterization. In two patients, who had only systolic murmurs, catheterization revealed mitral stenosis rather than mitral insufficiency. In four patients who were thought to have mixed valvular disease, left heart catheterization showed only aortic valvular disease.
经支气管途径进行左心导管插入术以获取左心房和左心室压力，在29例患者中成功应用，无死亡或发病情况。发现该方法有助于区分二尖瓣狭窄和二尖瓣关闭不全，以及在主动脉瓣受累时确定主动脉狭窄的程度。当存在主动脉瓣和二尖瓣疾病时，该技术也有助于确定主要病变。在29例患者中的2例中，左心导管插入术获得的数据避免了因错误诊断二尖瓣狭窄而进行手术，而实际上并无二尖瓣瓣膜疾病。在另外8例患者中，发现主要病变是二尖瓣狭窄而非导管插入术前认为的二尖瓣关闭不全。在2例仅有收缩期杂音的患者中，导管插入术显示为二尖瓣狭窄而非二尖瓣关闭不全。在4例被认为患有混合瓣膜疾病的患者中，左心导管插入术显示仅存在主动脉瓣膜疾病。
