  ventricular inlet
One important, but sometimes overlooked, consideration in valve function is the valve location relative to the tip of the ventricular inlet catheter.
      
The primary fold demarcates the border between the ventricular inlet segment of the heart, the Figure 1.
      
Because trabeculae are absent, the surface of the right ventricular inlet underneath the medial tricuspid leaflet is said to be smooth.

本文对结扎冠状动脉前降支的实验动物与冠心病患者用多普勒超声心动图(PDE)作左室舒张功能测定,同时对实验动物作心导管测压。发现结扎前降支后LAP及LVEDP增高,—dp/dt下降,两组PDE均显示左室流入道正峰降低,A峰增高。其EDC的下降与梗塞心肌重量(动物组)相关佳;0.5A/TA及0.33A/TA,EDC的改变随病变血管数增多而下降显著(临床组)。故上述指标对冠心病的诊断与预后评定有一定价值。

Four cases of isolated hypoplasia of the right ventricle diagnosed by cardioangiogrphy or pathology were reported.Major cardioangiographic findings were global hypoplasia of tripartite right ventricle,or dominant hypoplasia of trabecular and inlet portion of the right ventricle making a "sausage like" cavity,relatively small tricuspid valve and pulmonary valve.The proportion of tricuspid annulus to mitral annulus was less than 0.7.The important hemodynamic changes were caused by obstruction of the right ventricular...

Four cases of isolated hypoplasia of the right ventricle diagnosed by cardioangiogrphy or pathology were reported.Major cardioangiographic findings were global hypoplasia of tripartite right ventricle,or dominant hypoplasia of trabecular and inlet portion of the right ventricle making a "sausage like" cavity,relatively small tricuspid valve and pulmonary valve.The proportion of tricuspid annulus to mitral annulus was less than 0.7.The important hemodynamic changes were caused by obstruction of the right ventricular inlet flow and tricuspid regurgitation often associated with right-to-left shunt at the atria.Abnormal right ventricular pressure curve is of diagnostic significance in cases with no pulmonary stenosis.Differential diagnosis included restrictive cardiomyopathy and other cyanotic congenital heart diseases with pulmonary stenosis.

Objective To explore the clinical feasibility of right ventricular inlet septal pacing in order to get more physiological ventricular activation sequence. Method In 10 patients indicated for permanent VVI pacing tried to implant the pacing lead to the right ventricular inlet septal region under fluoroscopy and taking the tip of His bundle catheter as the reference.The pacing lead moved upward and distally to find the optimal implant location.If the local ventriculogram recorded during pacing appeared earlier than the V wave of His bundle electrogram and the shape of QRS wave during pacing is similar to that of spontaneous sinus beat,suggest the lead is located at the right ventricular inlet septal region. Results The lead and pulse generator were successfully implanted in all 10 patients.The average pacing threshold measured during implant procedure was (0 50±0 25) V.The QRS duration of paced beat was (124 77±11 35) ms.All patients were followed up 10 months,no significant change of pacing threshold was noted and no lead dislocation and other complications happened. Conclusion Right ventricular inlet septal pacing is clinically feasible.
