1. Meta-Analysis of Pulmonary Artery Denervation for Treatment of Pulmonary Hypertension
ABSTRACT Introduction: Pulmonary artery denervation (PADN) can reduce the sympathetic nervous system (SNS) activity, reduce pulmonary artery pressure (PAP), and improve the quality of life in patients with pulmonary hypertension (PH). We conducted a systematic meta-analysis of the effectiveness of PADN in the treatment of PH patients. Methods: This is a co

2. Early reduction of pulmonary arterial hypertension in patients using a long-term mechanical ventricular assistance device: a cross-sectional study
ABSTRACT BACKGROUND: Severe pulmonary arterial hypertension (PAH) is a contraindication for heart transplantation (HT). It has been correlated with increased early and late mortality, mainly associated with right ventricular failure. Ventricular assistance devices (VADs) can promote reduction of intracardiac pressures and consequent reduction of PAH over th

3. Pulmonary Thromboendarterectomy Without Circulatory Arrest
Abstract Introduction: Here we describe our technique and results of beating heart pulmonary thromboendarterectomy (PTE) with cardiopulmonary bypass (CPB) in four patients for treatment of chronic thromboembolic pulmonary hypertension (CTEPH). Methods: Retrospective analysis of data from patients who underwent PTE for CTEPH between January 2019 and Septemb

4. Possible association between a polymorphism of EPAS1 gene and persistent pulmonary hypertension of the newborn: a case-control study
Abstract Objective: To explore possible genes related to the development of persistent pulmonary hypertension of the newborn (PPHN). Methods: The authors identified 285 single nucleotide polymorphisms (SNPs) of 11 candidate genes (BMPR2, EPAS1, PDE3A, VEGFA, ENG, NOTCH3, SOD3, CPS1, ABCA3, ACVRL1, and SMAD9), using an Illumina Asian Screening Array-24 v1.0

5. Retrospective Evaluation of Platelet-Leukocyte Indices and Cardiac Surgical Outcomes in Acyanotic Heart Disease Patients with Pulmonary Hypertension (REPLICA-PH)
Abstract Introduction: Acyanotic congenital heart disease (ACHD) patients with pulmonary hypertension (PH) are prone to postoperative complications, and characterization of the risk profile continues to fail in identifying inflammatory predilection. Our objective is to investigate the role of platelet-leukocyte indices (neutrophil-lymphocyte ratio [NLR], pl

6. Indigo Carmine Hemodynamic Studies to Treat Vasoplegia Induced by Compound 48/80 in a Swine Model of Anaphylaxis
Abstract Introduction: There are many reasons to believe that the nitric oxide/guanosine 3’5’ - cyclic monophosphate (or NO/cGMP) pathway on vasoplegic states is underestimated. To study indigo carmine (IC) as an alternative to methylene blue was the investigation rationale. Methods: The IC (3mg/kg intravenous infusion) study protocol included five exp

7. In-hospital severe COVID-19 in a philanthropic tertiary hospital setting: is asthma a concern? A retrospective study
ABSTRACT BACKGROUND: The frequency of coronavirus disease 2019 (COVID-19) cases among asthmatics has been reported to be reduced. However, the findings regarding the association between asthma and the risk of severe COVID-19 have been divergent. OBJECTIVE: To investigate whether asthma is associated with a reduced risk of development of severe COVID-19. D

8. Cushing’s syndrome due to ectopic adrenocorticotropin secretion by a parotid carcinoma
SUMMARY We report a rare case of Cushing’s syndrome in a 37-year-old female who initially presented with localized acinic cell carcinoma of the parotid gland. In January 2014, she underwent a right parotidectomy with facial nerve preservation and adjuvant radiotherapy. In August 2018, she presented a histologically-proven local regional relapse. The patien

9. Lung function and stress echocardiography in pulmonary arterial hypertension: a cross-sectional study
ABSTRACT BACKGROUND: The mechanism of exercise limitation in idiopathic pulmonary arterial hypertension (IPAH) is not fully understood. The role of hemodynamic alterations is well recognized, but mechanical, ventilatory and gasometric factors may also contribute to reduction of exercise capacity in these individuals. OBJECTIVE: To investigate whether there

10. Coexistent Mitral Stenosis and left Circumflex Coronary Artery to left Atrial Fistula in a Patient with Severe Pulmonary Hypertension
Abstract Coronary artery to left atrial fistula is rare in patients with mitral stenosis. We report an interesting case of a patient with concomitant mitral valve stenosis and coronary fistulae, originating from the left circumflex artery and drained into the left atrium with two terminal orifices.

11. Transcatheter Interatrial Shunts for the Treatment of Heart Failure with Preserved Ejection Fraction
Abstract Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome, which accounts for about 50% of patients with heart failure (HF). The morbidity and mortality associated with HFpEF is similar to HFrEF. Clinical trials to date have failed to show a benefit of medical therapy for HFpEF, which may due to lack of uniform phenotypes and het

12. Prognosis of Heart Failure with Preserved Ejection Fraction in Primary Care by the H2FPEF Score
Abstract Background: Primary care physicians have difficulty dealing with patients who have HF with preserved LVEF(HFpEF). The prognosis of HFpEF is poor, and difficult to predict on primary care. Objective: The aim of the study is to apply the H2FPEF score to primary care patients and verify its power to assess the risk of death or hospitalization due to
