Abstract
We aimed to comprehensively analyze by three-dimensional speckle-tracking echocardiography (3DSTE) and Doppler echocardiography right ventricular (RV) performance, pulmonary arterial (PA) elastic properties and right ventricular-pulmonary artery coupling (RVPAC) in patients with repaired tetralogy of Fallot (rTOF) and assess the feasibility and clinical utility of related echocardiographic indices. Twenty-four adult patients with rTOF and twenty-four controls were studied. RV end-diastolic volume(3D-RVEDV), RV end-systolic volume(3D-RVESV), RV ejection fraction(3D-RVEF), RV longitudinal strain(3D-RVLS) and RV area strain(3D-RVAS) were calculated by 3DSTE. RV end-systolic area (RVESA) was obtained by planimetry. Pulmonary regurgitation (PR) was assessed as trivial/mild or significant by cardiac magnetic resonance (CMR) and color-Doppler. Pulmonary artery (PA) elastic properties were determined using two-dimensional/Doppler echocardiography. RV systolic pressure (RVSP) was measured using standard Doppler methods. RVPAC was assessed using various 3DSTE-derived parameters (3DRVAS/RVSP, 3DRVLS/RVESA, 3DRVAS/RVESV). Overall, 3DRVEF and 3DRVAS were impaired in rTOF patients compared with controls. PA pulsatility and capacitance were reduced (p = 0.003) and PA elastance was higher (p = 0.0007) compared to controls. PA elastance had a positive correlation with 3DRVEDV (r = 0.64, p = 0.002) and 3DRVAS (r = 0.51, p = 0.02). By ROC (receiver operating characteristics) analysis, 3DRVAS/RVESV, 3DRVAS/RVSP and 3DRVLS/RVESA cutoff values of 0.31%/mmHg, 0.57%/mmHg and 0.86%/mmHg, respectively, had 91%, 88% and 88% sensitivity and 81%, 81% and 79% specificity in identifying exercise capacity impairment. In rTOF patients increased 3DSTE-derived RV volumes and impaired RV ejection fraction and strain are associated with reduced PA pulsatility and capacitance and increased PA elastance. 3DSTE-derived RVPAC parameters using different afterload-markers are accurate indices of exercise capacity.

Transcatheter pulmonary valve implantation in 100 patients: a 10-year single-center experience. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2020; 16:235-243. [PMID: 33597988 PMCID: PMC7863798 DOI: 10.5114/aic.2020.99257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 08/30/2020] [Indexed: 11/25/2022] Open
Abstract
Introduction Transcatheter pulmonary valve implantation (TPVI) is a non-surgical method of treatment for patients with right ventricular outflow tract (RVOT) dysfunction after surgical repair of congenital heart defects (CHD). Aim To evaluate the long-term results of TPVI performed in a single center. Material and methods: Over 10 years, TPVI was performed in 100 patients (mean age: 26.4 ±8.1 years), using Melody Medtronic or Sapien Edwards valves. Results The initial success rate of TPVI was 93%. In 7 cases (5 urgent), a switch to surgical intervention was necessary due to periprocedural complications (all patients survived). Following TPVI, none of the 93 patients had severe pulmonary regurgitation. The pulmonary gradient decreased from 49.0 ±37.8 before to 27.6 ±14.9 mm Hg directly after TPVI (p < 0.0001). Right ventricular end-diastolic volume decreased, while NYHA class and pVO2 uptake significantly improved in 1 year after TPVI. Freedom from reintervention was 100% in 1 year. Freedom from serious adverse events was 86% in mean 5.5 years of observation. The main reason for reintervention was infective endocarditis (IE) (1.6% patients/year). Increased risk of IE was associated with severe PS before valve implantation and the suboptimal result of TPVI. The incidence of IE seems to be lower in patients treated permanently with antiplatelet therapy (1.8% vs. 0.9% patients/year, NS). Conclusions TPVI is a safe and effective method of treatment in patients with RVOT dysfunction after surgical correction of CHD. To achieve a good outcome, precise patient selection and rigorous IE prevention are necessary.
