The objective of this study was to assess the immediate and mid-term results transcatheter closure postinfarct muscular ventricular septal defects (VSDs) using new Amplatzer VSD device (PIMVSD). Ventricular rupture occurs in 0.2% myocardial infarcts remains associated with very high morbidity mortality. Data were prospectively collected for 18 patients who underwent attempted postinfarction VSDs between 2000 2003. Five acute phase (within 6 days from infarct); remaining on day 14-95 after...

To describe case mix variation among institutions, and report adverse event rates in congenital cardiac catheterization by type.Reported for patients with heart disease undergoing vary considerably, due to non-comparable standards of data inclusion, highly variable mix.The Congenital Cardiac Catheterization Outcomes Project (C3PO) has been capturing characteristics events (AE) all catheterizations performed at six pediatric institutions. Validity completeness were independently...

The Congenital Cardiac Catheterization Project on Outcomes (C3PO) was established to develop outcome assessment methods for pediatric catheterization.Six sites have been recording demographic, procedural and immediate data all cases, using a web-based system since February 2007. A sample of independently audited validity completeness. In 2006, participants categorized 84 procedure types into 6 categories by anticipated risk an adverse event (AE). Consensus empirical were used determine final...

This study was performed to determine whether a preoperative hemodynamic evaluation with oxygen and inhaled nitric oxide identifies patients pulmonary hypertension who are appropriate candidates for corrective cardiac surgery or transplantation more accurately than an alone.At 10 institutions, 124 heart disease severe underwent catheterization operability. The ratio of systemic vascular resistance (Rp:Rs) determined at baseline while breathing approximately 21% 30% oxygen, in 100% 80 parts...

Background: Percutaneous transcatheter pulmonary valve replacement (TPVR) has good clinical and hemodynamic outcomes in treating dysfunctional bioprosthetic valves (BPV) the position. Valve-in-valve therapy can further decrease inner diameter (ID), potentially resulting patient-prosthesis mismatch patients with smaller BPVs. Methods Results: To evaluate feasibility of intentional BPV fracture to enlarge orifice TPVR, 37 from 13 centers who underwent TPVR intended were evaluated. A control...

Experience with the use of biventricular assist device (BiVAD) support to bridge small children heart transplantation is limited.We used BIVAD (Berlin EXCOR) in 9 pediatric transplant candidates from 4/05 7/07. The median patient age was 1.7 years (12 days 17 years). weight 9.4 kg (3 38 kg). All were supported multiple intravenous inotropes+/-mechanical ventilation (6) or ECMO (3) before BiVAD implantation. had significant right ventricular dysfunction. pulmonary vascular resistance index...

Background Advancements in the field, including novel procedures and multiple interventions, require an updated approach to accurately assess patient risk. This study aims modernize hemodynamic procedural risk classification through creation of assessment tools be used congenital cardiac catheterization. Methods Results Data were collected for all cases performed at sites participating C3PO (Congenital Cardiac Catheterization Project on Outcomes) multicenter registry. Between January 2014...
