Abstract
Abstract
Background
There is an association between aortic stenosis and anaemia known as Heyde's syndrome. It is caused by an acquired von Willebrand (VW) deficiency related to turbulent flow. Patients with significant paravalvular leak (SPL) remain with VW deficit. The aim of this work is to assess impact on prognosis and anaemia of SPL.
Methods
Observational analytic study developed at two university hospitals, including all consecutive patients who underwent TAVI during a 10-year period (2009 to 2018). A logistic regression model was created to determine independent predictors of anaemia at 3 months. Time to event outcomes were analysed with Cox regression. Median follow-up was 21.3±21.9 months.
Results
5.3% of 788 patients had SPL, with no differences on their basal characteristics compared to the rest of the cohort. SPL was an independent predictor of anaemia 3 months after TAVI (Odds Ratio: 8.31, Confidence Interval 95% [CI]: 2.06–33.50).
SPL had negative impact on mortality: Hazard Ratio (HR): 1.85, CI 1.2–2.9; but not on cardiovascular mortality (CV): HR 1.13, CI 0.4–3.1. Patients who had anaemia three months after TAVI had an increased mortality. (HR 2.17, CI 1.5–3.3)
Conclusion
SPL after TAVI increases mortality with no impact on CV mortality. SPL is independent predictor of anaemia 3 months after TAVI, a condition that doubles the mortality. The impact of SPL on mortality could be explained by the increase in anaemia that SPL causes. More aggressive approach to SPL could have a benefit on prognosis.

Abstract
Abstract
Background/Introduction
Previous studies using conventional echocardiographic measurements have reported subclinical left diastolic dysfunction in patients with Marfan syndrome (MFS). Certain speckle-tracking echocardiography (STE) derived parameters have shown good correlation with invasive measurements of LV relaxation.
Purpose
To evaluate diastolic function in Marfan patients using STE-derived parameters along with traditional diastolic measurements and compare them with healthy controls.
Methods
We consecutively included 127 MFS patients with normal LV ejection fraction and no previous cardiovascular surgery or significant valvular regurgitation. We also studied 38 healthy controls (age and sex-matched). We performed LV and LA strain analysis using 2D STE (QLAB 10, Philips). Echocardiographic parameters recommended to assess diastolic function (according to ASE/EACVI 2016 guidelines) were also considered.
Results
Reported use of BB/ARB was 28/39% in MFS patients. According to current guidelines, all participants had normal diastolic function. MFS patients showed lower TDI e' velocities (septal and lateral) and higher average E/e' ratio compared to controls, but still within normal range. Regarding STE-derived measurements, LVGLS, EDLSR and PALS were significantly reduced in MFS. E/EDLSR ratio was higher among MFS patients, reflecting impaired LV relaxation. Interestingly, E/LVGLS was not different between both groups.
Conclusion
STE-derived parameters showed impaired LV relaxation in MFS patients compared to controls. Our results suggest that STE derived parameters can be markers of early diastolic dysfunction and provide a better insight into Marfan-related cardiomyopathy.

Clinical outcomes of percutaneous coronary intervention in coronary allograft vasculopathy from single center experience. Eur Heart J 2020.

Abstract
Abstract
Background/Introduction
Cardiac allograft vasculopathy (CAV) is a leading cause of morbidity and mortality of heart transplant recipients. Percutaneous coronary intervention (PCI) is an alternative to medical treatment, however long-term data from large multicenter studies are scarce.
Purpose
To review clinical characteristics and outcomes of CAV undergoing PCI in our heart transplant series.
Methods
We analysed retrospectively 52 heart transplant recipients with CAV who underwent PCI from 2004 to 2020. Surveillance angiography was performed in 90% of stents. Stent restenosis (SR), stent thrombosis (ST), target lesion revascularization (TLR) and patient survival are reported.
Results
During study period, 124 lesions were treated. Primary success was obtained in 99% of lesions. Mean angiographic follow up was 37±47 months. A total of 31 (25%) stents presented events during follow-up: 24 SR, 7 ST. There were no differences between bare-metal stent (BMS) and drug-eluting stent (DES). We performed 16 (12.9%) TLR. There was no association between clinical and lesion-related features and TLR. Post-PCI survival was 75.3% at 5 and 55.7% at 10 years.. Cytomegalovirus (CMV) infection before development of CAV decreased survival in univariable analysis (p<0.016).
Conclusions
PCI with stent in CAV can be performed with high rates of primary success and low rate of complications, similar to non-transplant patients. Our series suggest that CMV infection can have negative impact in post-PCI survival, but further studies are needed.
