Positive results of MitraClip in terms of improvement in clinical and left ventricular parameters have been described in detail. However, long-term effects on secondary pulmonary hypertension were not investigated in a larger patient cohort to date. 70 patients with severe mitral regurgitation, additional pulmonary hypertension, and right heart failure as a result of left heart disease were treated in the heart centers Hamburg and Göttingen. Immediately after successful MitraClip implantation, a reduction of the RVOT diameter from 3.52 cm to 3.44 cm was observed reaching a statistically significant value of 3.39 cm after 12 months. In contrast, there was a significant reduction in the velocity of the tricuspid regurgitation (TR) from 4.17 m/s to 3.11 m/s, the gradient of the TR from 48.5 mmHg to 39.3 mmHg, and the systolic pulmonary artery pressure (PAPsyst) from 58.6 mmHg to 50.0 mmHg. This decline continued in the following months (Vmax TR 3.09 m/s, peak TR 38.6 mmHg, and PAPsyst 47.4 mmHg). The tricuspid annular plane systolic excursion (TAPSE) increased from 16.5 mm to 18.9 mm after 12 months. MitraClip implantation improves pulmonary artery pressure, tricuspid regurgitation, and TAPSE after 12 months. At the same time, there is a decrease in the RVOT diameter without significant changes in other right ventricular and right atrial dimensions.

Abstract   The Pulmonary artery pulsatility index (PAPi) is a novel haemodynamic marker that has been shown to be a strong predictor of right heart failure and mortality in patients with pulmonary hypertension and advanced heart failure. Its utility in predicting post transplant outcomes is currently unknown. Aim To determine the prognostic significance of pre-transplant haemodynamic assessment of PAPi, right atrial pressure (RA), and pulmonary vascular resistance (PVR) in predicting mortality post cardiac transplant. Methods All patients who underwent cardiac transplantation between January 2010 and June 2016 were retrospectively analyzed. Pre-operative right heart catheter data was obtained. The PAPi was calculated as the systolic pulmonary artery pressure (sPAP)- diastolic pulmonary artery pressure (dPAP) divided by RA. Statistical analysis was carried out using SPSS v25. Results A total of 158 patients, with a mean age of 48.6±13.5 were studied (115 non- LVAD, 43 LVAD pre-transplant), and 3 patients were excluded due to missing data. There was no significant difference in the non-LVAD group in RA, PVR or PAPi for mortality post transplant. In the LVAD group there was no significant difference in RA, or PAPi with regards to mortality, however there was a significant difference in mean PVR between those that died post transplant (222±100) and those still alive (138±59) Conclusion Despite having a role in prognostication for right heart failure in pulmonary hypertension and post LVAD implantation, PAPi did not discriminate mortality outcomes for patients post cardiac transplantation. PVR remains a marker of mortality in an LVAD cohort bridged to transplant. Funding Acknowledgement Type of funding source: None

Abstract Background Systolic pulmonary artery pressure (SPAP) can be estimated non-invasively as the sum of indices for right atrial (RA) pressure and tricuspid regurgitation (TR) pressure gradient. Although echocardiographic evaluation of inferior vena cava diameter and collapsibility is currently being used to estimate RA pressure (IVC method), RA strain may be an alternative since atrial strain is related to atrial pressure. Objective We tested if RA strain by speckle tracking echocardiography can be used as a surrogate of mean RA pressure (RA strain method), and by adding the TR pressure gradient, be used to estimate SPAP. Methods We retrospectively analyzed 91 patients (mean age, 58 years) referred to right heart catheterization due to unexplained dyspnea or suspected pulmonary hypertension. Echocardiography was performed within 24 hours of the invasive procedure. RA reservoir strain was calculated from apical four-chamber view. SPAP was calculated as the sum of peak TR pressure gradient and estimated RA pressure by the IVC or RA strain methods. Results Right heart catheterization showed SPAP and mean RA pressures of 51±20 mmHg and 9±6 mmHg, respectively. RA reservoir strain was inversely correlated with mean RA pressure (r=−0.61, p<0.01). Thus, we set mean RA pressure as 5, 10 and 15 mmHg depending on high (≥25%), middle (10–25%) and low (≤10%) values of RA reservoir strain. As shown in the figure, both the RA strain and IVC methods when combined with peak TR velocity, provided good estimates of invasively measured SPAP. Conclusions RA strain provides a semiquantitative measure of RA pressure, which can be used in combination with peak TR velocity to estimate SPAP. This approach can be used as an alternative when the IVC method is not available in cases with poor subcostal window.

Abstract Background Doppler echocardiography is the most widespread and well-recognized technique for the screening of patients with pulmonary hypertension (PH). When tricuspid regurgitation peak velocity (TRPV) ≥3.4 m/s, right heart catheterization is requested to confirm mean pulmonary artery pressure &gt;25 mm Hg. In the proceedings from the 6th world symposium on pulmonary arterial hypertension recently released, the new definition of PH has been lowered to mean pulmonary artery pressure &gt; 20 mm Hg. Purpose The purpose of our work was twofold : i) to determine a new cut-off value for TRPV to accommodate the new hemodynamic definition of PH, ii) to investigate the impact on the demand of right heart catheterization (RHC) from our echo CORE lab. Methods We extracted and analyzed both the haemodynamic and echocardiographic records of 130 patients who underwent investigations the same day. Tricuspid regurgitation peak velocity was measured in apical-4 chamber view using continuous-wave doppler modality and compared to mean pulmonary artery pressure recorded from fluid-filled catheter. Results Tricuspid regurgitation peak velocity has a weak correlation with mean pulmonary pressure (y = 9.2x-2.2, r² = 0.22, p &lt; 0.01). Targeting a mean pulmonary pressure on right heart catheterization of 20 mm Hg for the definition of PH, receiver operating characteristic curve analysis demonstrated a good association between TRPV and PH diagnosis (area under the curve, 0.78 ; p &lt; 0.001). The cut-off value obtained for TRPV was 3.0 m/s (Se = 0.78, Sp = 0.37). From 01/01/18 to 31/12/18, 2539 out of 6215 had TRPV recorded from which 283 had TRPV ≥ 3.0 m/s (24,1%) and 615 had TRPV ≥ 3.4 m/s (11,1%). When applied to a community population the new TRPV cutoff &gt; 3m/s used as surrogate for mean pulmonary artery pressure &gt; 20 mm Hg may produce a 111% increase of right heart catheterization demand. Conclusions The new definition of pulmonary hypertension (invasive mean pulmonary artery pressure &gt; 20mm Hg) necessitates revisiting tricuspid regurgitation peak velocity &gt; 3 m/s as a screening test leading to more than twice RHC demand.

AbstractUnilateral interruption of pulmonary artery is a rare congenital anomaly which is usually associated with other congenital heart disease. Even more rarely it may occur in isolation. Most of the cases are incidentally detected in adulthood. Some cases develop pulmonary hypertension for yet unknown reasons; such cases usually present in infancy with right heart failure. Surgical correction in such cases is associated with adverse outcomes. Heart lung transplantation should be considered in such patients. We report a 3-year-old boy with interruption of right pulmonary artery with severe pulmonary hypertension and right heart failure who was considered for heart lung transplantation.

Aim. Develop new approaches to the diagnosis of right heart failure and pulmonary hypertension in recurrent thromboembolism of small branches of the pulmonary artery in patients with malignant tumors. Methods. 83 patients with malignant tumors of various localizations were examined and followed-up. The main group included 49 patients with malignant tumors of various localizations and related venous thrombosis. The control group included 34 patients who did not have venous thrombosis. Patients in both groups underwent ultrasonography of inferior vena cava system veins and echocardiography at intervals of 3-4 days during the diagnosis and treatment of malignant tumors. Right ventricle ejection fraction and systolic pressure in the pulmonary artery were calculated at echocardiography. Results. No signs of inferior vena cava system veins thromboses, right heart failure, pulmonary hypertension were identified in patients of the control group while setting up the diagnosis and treatment of malignancies. In 38 out of 49 patients of the main group, right ventricular failure and pulmonary hypertension of varying severity were detected. The condition of 46 patients of the main group gradually improved after treating with anticoagulants. Conclusion. Recanalization of venous thrombosis is accompanied by frequent rejection of micro thrombi and embolization of small branches of pulmonary artery, causing right heart failure and pulmonary hypertension, which can be promptly detected by repeated echocardiography.
