Han SW, Puelz C, Rusin CG, Penny DJ, Coleman R, Peskin CS. Computer simulation of surgical interventions for the treatment of refractory pulmonary hypertension. MATHEMATICAL MEDICINE AND BIOLOGY : A JOURNAL OF THE IMA 2023; 40:1-23.

Abstract
This paper describes computer models of three interventions used for treating refractory pulmonary hypertension (RPH). These procedures create either an atrial septal defect, a ventricular septal defect or, in the case of a Potts shunt, a patent ductus arteriosus. The aim in all three cases is to generate a right-to-left shunt, allowing for either pressure or volume unloading of the right side of the heart in the setting of right ventricular failure, while maintaining cardiac output. These shunts are created, however, at the expense of introducing de-oxygenated blood into the systemic circulation, thereby lowering the systemic arterial oxygen saturation. The models developed in this paper are based on compartmental descriptions of human hemodynamics and oxygen transport. An important parameter included in our models is the cross-sectional area of the surgically created defect. Numerical simulations are performed to compare different interventions and various shunt sizes and to assess their impact on hemodynamic variables and oxygen saturations. We also create a model for exercise and use it to study exercise tolerance in simulated pre-intervention and post-intervention RPH patients.

Abstract
Pulmonary hypertension (PH) is a prevalent disease of the pulmonary vasculature that is characterised by considerable morbidity and mortality. Substantial efforts have been made in recent years to improve disease recognition, diagnosis and management, and this is reflected in current guidelines. The haemodynamic definition of PH has been revised and a definition for exercise PH has been provided. Risk stratification has been refined and the importance of comorbidities and phenotyping have been highlighted. These changes provide an opportunity to potentially identify pulmonary vascular disease at an earlier stage and to enhance patient-centred, goal-orientated treatment decisions. A promising fourth treatment pathway for pulmonary arterial hypertension and potential targeted therapies for group 3 PH are on the horizon, concepts which seemed inconceivable only a few years ago. Beyond medication, there is a greater appreciation for the importance of supervised training in stable PH and the possible role of interventional therapies in select cases. The landscape of PH is changing and it is characterised by progress, innovation and opportunities. In this article, we highlight some of the new trends in PH, with a specific focus on the revised European Society of Cardiology/European Respiratory Society 2022 guidelines for the diagnosis and management of PH.

Abstract
OBJECTIVE Pulmonary arterial hypertension (PAH) is a chronic progressive disease that may lead to right heart failure (RHF) and early death. Balloon atrial septostomy (BAS) may be used for the palliative treatment of RHF from PAH. We present our contemporary institutional experience of utilizing BAS in idiopathic PAH (IPAH) patients with refractory RHF to investigate the effect on the safety, efficacy and long-term survival. METHODS This retrospective analysis included 12 IPAH patients with severe RHF from March 2017 to May 2019 who were assessed as high risk. All patients received standard treatment including combination of PAH-specific drugs. Graded BAS was performed on these patients due to unsatisfactory clinical response. Clinical, functional and hemodynamic variables before and immediately after the procedure were collected. 1-year follow-up outcomes and 3-year survival rate were further analyzed. RESULTS Successful septostomy was achieved in cases with no procedure-related complications. All patients obtained hemodynamic improvement immediately after the procedure. The WHO functional class and exercise endurance improved at 1-year follow-up, 7 of 12 patients achieved intermediate-low risk status, while the rest remained at intermediate-high risk. 2 patients died at 18 and 20 months due to malignant arrhythmia and advanced heart failure, respectively. Survival at 1 year and 3 years was 100% and 83.3%. CONCLUSIONS In selected IPAH patients with refractory RHF, BAS is an additional therapeutic strategy, especially when PAH-specific drugs could not achieve the treatment target. BAS can improve hemodynamic variables, bring clinical and cardiac functional benefits and increase the 3-year survival.

Abstract
INTRODUCTION Personalized and stable interatrial communication is an important palliative therapy for patients with heart failure. However, this remains a technically challenging task. AREAS COVERED In the past decades, substantial advancements in atrial septostomy for the creation of controllable and durable interatrial communication have been made, and numerous novel devices and techniques are in various stages of development. In this review, we discuss the evolving indications for atrial septostomy, current approaches with or without device implantation, and indicators for optimal interatrial communication. The combined use of radiofrequency ablation and balloon dilation (CURB) is an individualized management approach based on underlying hemodynamics, which demonstrates unique advantages in creating a sufficient interatrial communication with satisfactory stability. The advantages and disadvantages of this implant-free procedure are analyzed and its clinical prospects are assessed. EXPERT OPINION With ready availability, high safety, and efficacy, CURB is a promising procedure for creating personalized and stable interatrial communication without device implantation. Further research is required to simplify the procedure, screen optimal reference parameters for personalized therapy, and evaluate the long-term outcome in a large population of patients.

Abstract
In recent years, percutaneous catheter interventions have continuously evolved, becoming an essential strategy for interventional diagnosis and treatment of many structural heart diseases and arrhythmias. Along with the increasing complexity of cardiac interventions comes ever more complex demands for intraoperative imaging. Intracardiac echocardiography (ICE) is well-suited for these requirements with real-time imaging, real-time monitoring for intraoperative complications, and a well-tolerated procedure. As a result, ICE is increasingly used many types of cardiac interventions. Given the lack of relevant guidelines at home and abroad and to promote and standardize the clinical applications of ICE, the members of this panel extensively evaluated relevant research findings, and they developed this consensus document after discussions and correlation with front-line clinical work experience, aiming to provide guidance for clinicians and to further improve interventional cardiovascular diagnosis and treatment procedures.

Abstract
ZusammenfassungDie pulmonale Hypertension (PH) ist eine progressive Gefäßerkrankung und führt über eine Widerstands- und/oder Druckerhöhung im kleinen Kreislauf zu einem fortschreitenden Rechtsherzversagen. Auch wenn mithilfe aktueller medikamentöser Therapien eine deutliche Verbesserung der Lebensqualität und des Überlebens der Betroffenen erreicht werden konnte, bleibt die PH eine zumeist nichtheilbare Erkrankung, die im fortgeschrittenen Stadium eine Lungentransplantation notwendig macht. Interventionelle Verfahren, wie die Anlage eines interatrialen Shunts (z. B. durch atriale Septostomie oder den Atrial Flow Regulator) oder eines Reversed Potts Shunt, verbessern die RV-Funktion und die ventrikuläre Interaktion durch Schaffung einer prä- oder posttrikuspidalen „Eisenmenger-Physiologie“ und stellen eine Überbrückung oder sogar Alternative zur Lungentransplantation dar. Bei Patienten mit segmentaler PH oder chronisch thrombembolischer pulmonaler Hypertension (CTEPH) stellt die Ballonangioplastie eine bereits etablierte Intervention zur Verbesserung der pulmonalen Perfusion und damit rechtsventrikulären (RV-)Funktion dar. Dagegen ist die pulmonalarterielle Denervation ein neuartiges Verfahren, mit dem Ziel, die neurohumorale Dysregulation bei PH positiv zu beeinflussen. Der individuelle Einsatz solcher Interventionen, additiv zu den bereits etablierten medikamentösen Therapien, erweitert die Behandlungsmöglichkeiten und kann die Prognose betroffener Patienten noch weiter verbessern.

Abstract
Despite significant advancements in pharmacological treatment, interventional and surgical options are still viable treatments for patients with pulmonary arterial hypertension (PAH), particularly idiopathic PAH. Herein, we review the interventional and surgical treatments for PAH. Atrial septostomy and the Potts shunt can be useful bridging tools for lung transplantation (Ltx), which remains the final surgical treatment among patients who are refractory to any other kind of therapy. Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) remains the ultimate bridging therapy for patients with severe PAH. More importantly, VA-ECMO plays a crucial role during Ltx and provides necessary left ventricular conditioning during the initial postoperative period. Pulmonary denervation may potentially be a new way to ensure better transplant-free survival among patients with the aforementioned disease. However, high-quality randomized controlled trials are needed. As established, obtaining the Eisenmenger physiology among patients with severe pulmonary hypertension by creating artificial defects is associated with improved survival. However, right-to-left shunting may be harmful after Ltx. Closure of the artificially created defects may carry some risk associated with cardiac surgery, especially among patients with Potts shunts. In conclusion, PAH requires an interdisciplinary approach using pharmacological, interventional, and surgical modalities.

Outcomes of Atrioseptostomy with Stenting in Patients with Pulmonary Arterial Hypertension from a Large Single-Institution Cohort. Diagnostics (Basel) 2020; 10:diagnostics10090725.

Abstract
The aim of this study was to analyze results of stenting atrioseptostomy in patients with pulmonary arterial hypertension and a different level of risk for one-year mortality that is not well described. Patients that underwent atrioseptostomy with stenting were retrospectively divided in two groups: "intermediate" (n = 55) or "high" risk (n = 13), according to the 2015 ESC/ESR guideline. Results of atrioseptostomy were assessed during hospital period and at follow-up. Patients from "intermediate" risk group demonstrated lower mortality rate (10/55, vs. 6/13) during the course of the study period, as well as higher freedom from lung transplantation or Potts shunt. At discharge, patients of both groups presented improvement in functional class and mobility. Patients from "intermediate" risk group showed longer 6-min walking distance, and lower levels of brain natriuretic peptide. At the latest follow-up, stable position and full patency of stents with right-to-left or bidirectional shunt at atrial level and absence of syncope was confirmed in patients of both groups. Patients from the "intermediate" risk group demonstrated higher functional class, better performance of walking test, and lower levels of brain natriuretic peptide. Stenting atrioseptostomy reliably secured interatrial communication and improved clinical condition in patients with idiopathic pulmonary arterial hypertension. Mid-term results were better in "intermediate" risk group.

Abstract
Despite advances in drug therapy, pulmonary hypertension-particularly arterial hypertension (PAH)-remains a fatal disease. Untreatable right heart failure (RHF) from PAH eventually ensues and remains a significant cause of death in these patients. Lowering pulmonary input impedance with different PAH-specific drugs is the obvious therapeutic target in RHF due to chronically increased afterload. However, potential clinical gain can also be expected from attempts to unload the right heart and increase systemic output. Atrial septostomy, Potts anastomosis, and pulmonary artery denervation are interventional procedures serving this purpose. Percutaneous balloon pulmonary angioplasty, another interventional therapy, has re-emerged in the last few years as a clear alternative for the management of patients with distal, inoperable, chronic thromboembolic pulmonary hypertension. The current review discusses the physiological background, experimental evidence, and potential clinical and hemodynamic benefits of all these interventional therapies regarding their use in the setting of RHF due to severe pulmonary hypertension.

Abstract
AIMS Elevated filling pressures of the left atrium (LA) are associated with poorer outcomes in patients with chronic heart failure. The V-Wave is a new percutaneously implanted device intended to decrease the LA pressure by the shunting of blood from the LA to the right atrium. This report describes the first-in-man experience with the V-Wave device. METHODS AND RESULTS A 70-year-old man with a history of heart failure of ischaemic origin, left ventricular dysfunction (LVEF: 35%, pulmonary wedge: 19 mmHg), no right heart dysfunction, NYHA Class III and orthopnoea despite optimal treatment, was accepted for V-Wave device implantation. The device consists of an ePTFE encapsulated nitinol frame that is implanted at the level of the interatrial septum and contains a trileaflet pericardium tissue valve sutured inside which allows a unidirectional LA to right atrium shunt. The procedure was performed through a transfemoral venous approach under fluoroscopic and TEE guidance. The device was successfully implanted and the patient was discharged 24 hours after the procedure with no complications. At three-month follow-up a left-to-right shunt through the device was confirmed by TEE. The patient was in NYHA Class II, without orthopnoea, the Kansas City Cardiomyopathy index was 77.6 (from 39.1 at baseline) and NT-proBNP was 322 ng/mL (from 502 ng/mL at baseline). The QP/QS was 1.17 and the pulmonary wedge was 8 mmHg, with no changes in pulmonary pressure or right ventricular function. CONCLUSIONS Left atrial decompression through a unidirectional left-to-right interatrial shunt represents a new concept for the treatment of patients with left ventricular failure. The present report shows the feasibility of applying this new therapy with the successful and uneventful implantation of the V-Wave device, which was associated with significant improvement in functional, quality of life and haemodynamic parameters at 90 days.

Abstract
Despite significant advances in pharmacological treatments, pulmonary arterial hypertension remains an incurable disease with an unreasonably high morbidity and mortality. Although specific pharmacotherapies have shifted the survival curves of patients and improved exercise endurance as well as quality of life, it is also true that these pharmacological interventions are not always accessible (particularly in developing countries) and, perhaps most importantly, not all patients respond similarly to these drugs. Furthermore, many patients will continue to deteriorate and will eventually require an additional, non-pharmacological, intervention. In this review we analyze the role of atrial septostomy and Potts anastomosis in the management of patients with pulmonary arterial hypertension, we summarize the current worldwide clinical experience (case reports and case series), and discuss why these interventional/surgical strategies might have a therapeutic role beyond that of a "bridge" to transplantation.

Abstract
Pulmonary arterial hypertension (PAH) is a rare disease, but it boasts significant morbidity and mortality. Although remarkable achievements have been made in the medical treatment of PAH, there is a role for invasive or surgical procedures in patients with progressive disease despite optimal medical therapy or with no access to such therapy. Atrial septostomy creates a right-to-left intracardiac shunt to decompress the overloaded right ventricle. Despite significant advances to validate and improve this palliative procedure, as well as recent reports of improved outcomes, it is only slowly being adopted. This article aims to detail the history, indications, contraindications, procedural techniques, and outcomes of atrial septostomy. We will also shed light on some of the newer interventions, inspired by the same physiological concept, that are being evaluated as potential palliative modalities in patients with PAH.

Abstract
The Third International Right Heart Failure Summit (Boston, MA) convened a group of international clinical and scientific experts in pulmonary vascular disease and right heart disease to explore cutting-edge developments in the mechanisms and clinical management of right-sided cardiovascular disease. The symposium was organized into three distinct sessions, the first of which was titled "Pulmonary Hypertension and the Right Ventricle-Thinking outside the Box" and will be the focus of this review. Three internationally renowned experts in pulmonary hypertension and right heart disease-Drs. Stuart Rich, Sean Gaine, and Harm Bogaard-each delivered provocative lectures. The first lecture, by Dr. Rich, was titled "Current Classification for Pulmonary Hypertension-Why Are We Ignoring the Structural Basis of the Disease?" Rich focused on the current classification system of pulmonary hypertension and provided a unique historical perspective. He also addressed the need to evolve the prevailing conceptual framework of our approach to pulmonary vascular diseases and right ventricular dysfunction, including the future design of pulmonary hypertension clinical trials. Dr. Gaine delivered the second lecture, titled "Treatment Algorithm for Pulmonary Hypertension: Tunnel Vision of our Current Approach." Gaine emphasized the tripartite model of pulmonary hypertension management, namely, supportive measures, pharmacologic therapy, and rescue therapy. Specifically, he detailed how each of these entities is changing as our understanding of the unmet needs in the field of pulmonary hypertension is becoming increasingly apparent. Finally, Dr. Bogaard provided a lecture titled "Treating Right Heart Failure: Why Does the Art of Medicine Lead the Science?" Bogaard provided a stimulating review of cutting-edge translational research of right ventricular function and dysfunction. In particular, he described a variety of molecular and cellular changes that occur in the hypertrophied right ventricle and contrasted those changes that may be adaptive from those that are maladaptive and may be potential therapeutic targets.
