RESUMEN
With the development of progressive right ventricular dysfunction, pulmonary arterial hypertension (PAH) is one of the causes of type 2 cardiohepatic syndrome (CHS). Risk assessment, timely and effective management are crucial to improve survival in PAH. Thus, we aimed to evaluate the presence of CHS at diagnosis and its association with prognosis in patients with PAH. One hundred and eighteen consecutive incident patients with PAH between January 2013 and June 2021 were retrospectively included. The presence of CHS was assessed from blood tests taken during diagnostic evaluation and was defined as elevation of at least two of three cholestatic liver parameters; total bilirubin, alkaline phosphatase and gamma-glutamyl transferase. The primary endpoint was all-cause mortality. Patients were followed for a median period of 58 (32-96) months. 23.7% of the patients had CHS at diagnosis. Significantly more patients in CHS (+) group were in intermediate and high-risk categories according to 2015 ESC/ERS guideline, REVEAL 2.0 and REVEAL Lite 2 risk assessment methods (p = .02, .03 and <.001, respectively). The presence of CHS was identified as an independent predictor of mortality (HR: 2.17, 95% CI: 1.03-4.65, p = .03) along with older age (HR: 2.89, 95% CI: 1.50-5.56, p = .001) and higher WHO functional class (HR: 2.57, 95% CI: 1.07-6.22, p = .03). To conclude, presence of CHS at diagnosis in patients with PAH was associated with severe disease and poor prognosis independent of other well known risk factors. As a simple and easy parameter to assess from routinely taken blood tests, CHS should be evaluated in patients with PAH.

BACKGROUND: Although transradial approach has been increasingly preferred for percutaneous coronary interventions, radial artery spasm (RAS) is still one of the major disadvantages. Flow-mediated dilation (FMD) is a well-known method for assessing endothelial function through dilation. The aim of this study was to investigate the efficacy of prepuncture flow mediated dilation in preventing RAS during transradial approach. METHODS: The present study prospectively included 222 consecutive patients who underwent transradial coronary intervention. Patients were 1:1 randomized into two groups who underwent prepuncture FMD and who did not (FMD [+] and FMD [-], respectively). RESULTS: In FMD [+] group the incidence of RAS was lower (5.4% vs. 16.2%, P=0.009). Multivariate logistic regression analysis demonstrated that female sex, more than two catheter usage and transradial approach without prepuncture FMD independently predicted RAS (odds ratio [OR]=4.66, 95% confidence interval [CI]: 1.8-12.06, P=0.001, OR=5.73, 95% CI: 2.01-16.39, P=0.001, and OR=5.01, 95% CI: 1.74-14.48, P=0.003; respectively). However, access site crossover number was very low in both groups and not different between groups. CONCLUSIONS: Prepuncture FMD can significantly reduce RAS during transradial coronary interventions. Thus, prepuncture FMD can be used as a simple adjunctive method to prevent RAS.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is recommended in patients with severe aortic stenosis who have high surgical risk. However, in the pre-existing mechanical mitral valve prosthesis and natural pure aortic regurgitation, TAVR is relatively contraindicated. In this report, we described one case of TAVR with native aortic regurgitation in the presence of mechanical mitral valve prosthesis. CASE SUMMARY: A 64-year-old man with a medical history of mitral valve replacement had severe dyspnea and was symptomatic even at rest for 3 mo. His echocardiography showed severe native pure aortic regurgitation. His euroscore was 15. A TAVR procedure with an evolut R was planned. A 34 mm evolut R was placed by transesophageal echocardiography. The mitral prosthesis was functioning normally, and mild-moderate paravalvular leakage was evident by transesophageal echocardiography. The patient recovered without any complication. At 1 mo follow up, the patient was well, and no paravalvular leakage was noted. CONCLUSION: TAVR for pure aortic regurgitation in the presence of prosthetic mitral valve can be a safe procedure.
RESUMEN
This report sought to compare live/real-time three-dimensional transesophageal echocardiography (3D-TEE) with two-dimensional transesophageal echocardiography (2D-TEE) and to determine whether there are advantages to using 3D-TEE on patients with pulmonary stenosis (PS). Sixteen consecutive adult patients (50 % male and 50 % female; mean age 33 ± 13.4 years) with PS and indications of TEE were prospectively enrolled in this study. Following this, initial 2D-TEE and 3D-TEE examinations were performed, and 3D-TEE images were analyzed using an off-line Q-lab software system. Finally, the 2D-TEE and 3D-TEE findings were compared. In the present study, 3D-TEE allowed us to obtain the en face views of pulmonary valves (PVs) in all but one patient. While this patient was without a PV due to a previous tetralogy of Fallot operation, we could detect the type of PV in the other 15 (93.7 %) patients by using 3D-TEE. Due to poor image quality, the most stenotic area was not measurable in only one (6.2 %) of the patients. In eight (50 %) of the patients, severity and localization of stenosis were more precisely determined with 3DTEE than with 2D-TEE. The PVs' maximal annulus dimensions were found to be significantly larger when they were measured using 3D modalities. This study provides evidence of the incremental value of using 3D-TEE rather than 2D-TEE during assessments of PS, specifically in cases where special conditions (pregnancy, pulmonary regurgitation, and concomitant atrial septal defects) cause recordings of the transvalvular peak gradient to be inaccurate. Therefore, 3D-TEE should be used as a complementary imaging tool to 2D-TEE during routine echocardiographic examinations.
