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 CONTEXT: Obstruction of the right ventricular outflow tract due to metastatic disease is rare. Clinical recognition of cardiac metastatic tumors is rare and continues to present a diagnostic and therapeutic challenge. CASE REPORT: We present the case of a patient who had severe respiratory insufficiency and whose clinical examinations revealed a giant tumor mass extending from the right ventricle to the pulmonary artery. We discuss the diagnostic and therapeutic options. CONCLUSION: In patients presenting with acute right heart failure, right ventricular masses should be kept in mind. Transthoracic echocardiography appears to be the most easily available, noninvasive, cost-effective and useful technique in making the differential diagnosis.

Abstract Background: Right ventricular (RV) failure induced by sustained pressure overload is a major contributor to morbidity and mortality in several cardiopulmonary disorders. Reliable and reproducible animal models of RV failure are important in order to investigate disease mechanisms and effects of potential therapeutic strategies. To establish a rat model of RV failure perfectly, we observed the right ventricle and carotid artery hemodynamics characteristics in different degrees of pulmonary artery banding of rats of different body weights. Methods: Rats were subjected to 6 groups:control(0%, n=5)(pulmonary arterial banding 0%), PAB(1-30%, n=4)(pulmonary arterial banding1-30%), PAB(31-60%, n=6)(pulmonary arterial banding31-60%),PAB(61-70%, n=5)(pulmonary arterial bandin61-70%), PAB(71-80%,n=4)(pulmonary arterial banding71-80%), PAB(100%, n=3)(pulmonary arterial banding 100%). We measured the right ventricular pressure(RVP) by right heart catheterization when the pulmonary arterial was ligated. Results: The RVP gradually increased with increasing degree of banding, but when occlusion level exceeding 70%, high pressure state can be only maintained for a few minutes or seconds, and then the RVP drops rapidly until it falls below the normal pressure, which in Group F particularly evident.Conclusions: RVP have different reactions when the occlusion level is not the same, and the extent of more than 70% ligation is a successful model of acute right heart failure. These results may have important consequences for therapeutic strategies to prevent acute right heart failure.
