Background: Transcatheter Interatrial Septal Defect Closure using Amplatzer was done in di erent centers. Experience of operator for select of best size of Amplatzer in this pro- cedure could decreased complications.
Objectives: We studied immediate and midterm results of transcatheter closure of atrial septal defects (ASDs) using Amplatzer septal device closure.
Materials and Methods: The study included one hundred thirty seven patients (thirty one men, one hundred-six women; mean age 8 ± 7.3 years; range 1–65 years) who underwent transcatheter closure of secundum ASD between Oct 2014 and Oct 2016 in our center. All the patients were evaluated by transthoracic echocardiogra- phy before and during the procedure and in adult patients, transesophageal echocardiography was performed before and during the procedure. Closure of ASDs was performed under general anesthesia with transesthorasic echocardi- ography guidance. Follow-up controls were done at the day after procedure, one week, 1, 3, 6, and 12 months and annually thereafter. The median follow-up periods of ASD were 15 months.
Results: The mean ASD and device size were 14.5± 3.3 and 16.3 ± 4.2 mm respectively. The mean procedural and uoroscopy times were 21.3 ± 4.7 and 5.1 ± 1.9 minutes. Immediate complication such as mortality, bleeding, fatal arrhythmia and device embolization did not occurred in any patients during and after the procedure. Cardiac arrhyth- mia were occured in 4 patients during the rst month after the procedure. Late device embolization did not occurred during the follow-up. No residual shunts were seen after procedure. Transient ischemic attack was occured in one patient during the procedure and in one patient 2 days after the procedure without long term complication.
Conclusion: Transcatheter closure of ASDs using the Amplatzer devices is an ef cacious and safe therapeutic
option and had low complications and could done in suit- able patients.
16. PROCEDURAL AND SHORT OUTCOMES OF TRANSCATHETER RADIOFREQUENCY-ASSISTED PULMONARY VALVOTOMY AND BALLOON VALVULOPLASTY OF PATIENTS WITH PULMONARY ATRESIA WITH INTACT INTERVENTRICULAR SEPTUM Judah Gozar
Philippine General Hospital, Manila, Philippines
Background: Pulmonary atresia-intact interventricular sep- tum (PA-IVS) is a rare congenital heart disease. To improve cardiac circulation, the goal now is to carefully select patients to achieve a biventricular repair via transcatheter radiofrequency-assisted pulmonary valvotomy and bal- loon valvuloplasty (TRFAPV-BV) and to avoid early open heart surgery. Success rates of >80% have been reported. Due to its rarity, no single institution can provide a consis- tent interventional guideline. There is much to be learned from a multicentered approach to collecting longitudinal experience to a challenging clinical case.
Objective: We report our procedural and short-term out- comes in our patients who have undergone TRFAPV-BV with an emphasis on possibly identifying the predictors for survival and the need for additional transcatheter right ventricular out ow tract (RVOT) reintervention.
Methodology: This is a retrospective, descriptive, cohort study of all patients with PA-IVS who underwent TRFAPV-BV from Decemeber 2013 to April 2016. The hospital medi- cal records of each patient was reviewed. Transthoracic two dimensional echocardiogram reports and clips, and cardiac catheterization reports pre and post-TRFAPV-BV were reviewed. In addition, each patient’s clinical course through medical records were examined until their most recent clinical follow-up.
Results: There are 29 pediatric patients diagnosed with PA-IVS between December 2013 to April 2016. Out of these 29 patients with PA-IVS, 9 pediatric patients had a tripar- tite right ventricle underwent TRFAPV-BV, in whom 8 were described as successful, 89% (8/9). This study observed that the following paremeters had a favorable outcome: tricuspid valve (TV) annulus z-score > -2.5, tripartite right ventricle, absence of ventricular to coronary connections, tricuspid to mitral vale ratio >0.5 and right-to-left ven- tricular pressure ratio of >1. Moreover, parameters after TRFAPV-BV of higher residual gradient across pulmonary
