BACKGROUND: Infective endocarditis (IE) poses significant risks following percutaneous pulmonary valve implantation (PPVI) or surgical replacement (PVR).
AIMS: This study evaluates the effectiveness of emergency percutaneous treatment in stabilizing patients with severe right ventricular dysfunction or obstructive cardiac shock, allowing for delayed surgical or percutaneous valve replacement.
METHODS: This retrospective study examines 16 patients (age 19.9 [15.1-43.3] years) with right-sided IE treated with primary percutaneous intervention. Data collected included cardiac diagnosis, valve types, pathogens identified, procedural details, and outcomes.
RESULTS: Underlying diagnoses included aortic valve stenosis post-Ross surgery (43%), repaired tetralogy of Fallot (25%), common arterial trunk (18%), and repaired double outlet right ventricle (14%). Valve types varied, with Contegra Ven-Pro (56%) and Melody-valve (25%) being the most common. Diagnosis of IE occurred 66.5 (28.3-87.4) months postlast intervention/surgery, with emergency percutaneous treatment performed 2 (1-17) days postdiagnosis. Clinical presentations included obstructive cardiac shock (50%) and septic shock (25%). Preintervention RVOT velocity was 4.4 (4.2-5) m/s, with severely reduced RV function in 68%. Interventions included balloon dilatation, uncovered or covered stent implantation, and Melody valve implantation. Immediate resolution of RVOT obstruction was achieved in all patients, with significant reductions in RV systolic pressures (mean reduction 42.0 (30.2-50.0) mmHg) and improved RV function. No periprocedural deaths occurred, but one complication was noted. Follow-up included surgical repair (68%) and PPVI (18%). Mortality included one IE relapse and one surgical death.
CONCLUSIONS: Emergency percutaneous interventions can stabilize patients with RVOT obstruction due to IE, enabling delayed surgical or percutaneous interventions.
