Echocardiography and catheter examination at 10 months of age disclosed severe organic stenosis of left ventricular outflow tract (LVOT) with its diameter of 5.6 mm (50% of N) and the left to right ventricular (LV/RV) pressure ratio of 0.6. At 1.8 years of age, he underwent complete correction which comprised intraatrial switch (Senning procedure), direct closure of VSD, and removal of thickened endocardium at LVOT. Because of the residual LVOTO, evidenced by postoperative LV/RV pressure ratio of 1.4, placement of 14 mm PTFE graft extracardiac conduit was concomitantly performed. The conduit from the left ventricular apex to the main pulmonary artery effectively lowered the left ventricular pressure with LV/RV pressure ratio of 0.68. Repeat catheter examination at 2.10 years of age revealed further descent of LV/RV pressure ratio to 0.32. Based on the findings that balloon occlusion of the conduit elicited only a minimal elevation of the left ventricular pressure (from 30 to 34 mmHg), the conduit was removed at 3.6 years of age. The third catheter examination at the age of 3.9 years confirmed LV/RV pressure ratio of 0.43. The patient is leading a normal life. without medication 3 years after the operation. This experience draws us to conclude that placement of left ventricle-to-pulmonary artery conduit concomitantly with the intraatrial switch is a useful adjunctive procedure for the complete correction of TGA, small VSD, and LVOTO, and that, in a subset of the patients, this procedure may allow amelioration of LVOTO and secondary removal of the conduit.</p>","PeriodicalId":6434,"journal":{"name":"[Zasshi] [Journal].

Rat hearts were studied and divided into three groups; ST. UW and BR. In each group, six hearts were carried out perfusion, cardioplegic infusion, ischemia and reperfusion for four different conditions. Using an isolated working rat heart model, the hearts were subjected to 5 minutes Langendorff perfusion followed by 20 minutes working perfusion. During this working period, cardiac functions such as aortic and coronary flow, aortic pressure, and heart rates were measured every 5 minutes. After working perfusion, 3 minutes of cardioplegic infusion was carried out either with UW, ST, and BR at 37, 20, 4, 1 degree C. The hearts were subjected to either 35 min at 37 degrees C, 120 min at 20 degrees C, 300 min at 4 degrees C, or 450 min at 1 degree C. The hearts were immersed in the same solution during ischemia. The hearts were reperfused at 37 degrees C, initially in the Langendorff mode for 15 min. Coronary effluent was collected for the measurement of CK leakage during reperfusion. The heart were then converted to the working mode for 20 minutes. During working reperfusion period, the variables of cardiac function were again measured and expressed as a percentage of their individual preischemic control values. Under conditions of 37 degrees C ischemia, % recovery of cardiac output (%CO) in ST group is 62.8 +/- 2.8%, although the hearts preserved with UW and BR were not recovered. Under conditions of 20 degrees C ischemia, %CO in UW, ST and BR were 46.8 +/- 2.7, 82.0 +/- 3.1 and 41.4 +/- 2.6%, respectively. Under conditions of 4 degrees C ischemia, %CO in UW, ST and BR were 66.2 +/- 8.0, 68.6 +/- 2.3 and 47.2 +/- 2.9%, respectively. Under conditions of 1 degrees C ischemia, %CO in UW, ST and BR were 70.6 +/- 3.3, 56.5 +/- 1.6 and 43.0 +/- 2.5%, respectively. In conclusions, ST revealed the best protective properties for the heart preservation between 37 degrees C and 20 degrees C ischemia. The properties of ST was similar to that of UW under conditions of 4 degrees C, although UW showed most excellent protective properties under conditions of 1 degrees C ischemia. These results suggested that, protective ability of preservation solution might be changed by the temperature during preservation period.</p>","PeriodicalId":6434,"journal":{"name":"[Zasshi] [Journal].

Emax, which is an index of left ventricular contractility on PV loop, improved and pressure-volume area (PVA) which is correlated with 02 consumption of left ventricule was reduced. Mechanical efficiency of left ventricular energetic state did not significantly change. Left ventricular volume and ejection fraction in TOF slightly increased after the operation. Increased ejection fraction reflected a compensation to volume overload after surgery. Emax slightly decreased and PVA increased. Meanwhile mechanical efficiency increased after the operation indicating well preserved ventricular contractility. In particular, the shape of PV loop of both VSD and TOF eventually became usual square after operation due to recover of the isovolumic contraction and relaxation phase.
