Intact ventricular septum with pulmoner atresia or critical pulmonary stenosis is a rare anomaly of the Congenital Heart Diseases(CHD). It is seen aproximately in 3% of all CHDs. Management strateggies may vary. Patients clinical status, the development stage of right ventricle, tricuspit area, right ventricle end diastolic diameter and right ventricle dependent coronary arterial circulation are the most important criteria of choosing the treatment modality. Transient transcatheteric approaches and urgent surgical procedures play an important role as the life-saving procedures in patients that have a chance of biventricular operation and ductus dependent circulation in the newborn period . We described in here pulmonary atresia with intact ventriculary septum with newborn was perforeted with transient transcatheteric approaches. Firstly 4 F right coronary catheter was placed at the level of the pulmonary atrethic valve . Then atrethic valve was perforated by gentle end of 0.014 guidewire. When 0.014 guidewire placed on pulmonary arter, 0.021 wire was pushed forward to pulmonary arter, then advanced to the patent ductus arteriosus. Snare wire was pushed forward to descending aorta within 4 F multipurpose catheter. Guide wire was caught by snare catheher which was fixed at descending aorta. Therefore support was provided to balon angioplasty procedure. Finally baloon angioplasty was performed with 6x3 mm baloon. By the opaque injection passage from pulmonary valve was demonstrated but tricuspit failure was still keeping on. Spo2 obtained by pulse oximeter was 89%. Our modified mechanichal technique can be a good alternative for other approaches.
