Background: Right heart failure (RHF) is an unresolved issue during continuous-flow left ventricular assist device (LVAD) support. There are scarce data about post-transplant outcomes in patients complicated with late RHF during LVAD support.. Objective: To assess whether development of late RHF during LVAD support adversely affected post-transplant survival.. Methods: Between May 2004 and December 2013, 141 patients underwent cardiac transplantation after isolated LVAD support as a bridge to transplant at our center. Late RHF was defined as HF requiring medical interventions ,4 weeks after LVAD implantation. During the same study period, 3 patients were bridged to transplant with concurrent right ventricular assist device (RVAD) support.. Results: The mean age of the study cohort was 54 ± 13 years, 81% were male, and 35% had an ischemic etiology. The mean duration of LVAD support before transplantation was 270 days. Twenty-three patients (16%) developed late RHF during waiting period. Of ...

Introduction: Stenosis in the continuous-flow left ventricular assist device (CF-LVAD) outflow graft can be caused by various mechanical and anatomical factors. Increasingly, percutaneous management has been utilized to re-establish adequate CF-LVAD flow. We sought to evaluate indications for such interventions and their outcomes. Methods: An electronic search was performed to identify all studies in the English literature reporting CF-LVAD outflow graft stenting for various etiologies. Twenty-one studies consisting of 26 patients were included in the analysis. Results: Median patient age was 59 years [45.8-67.0] and 65.4% (17/26) were male. 58.3% (14/24) of patients had HeartWare HVAD, 37.5% (9/24) had HeartMate II LVAD, and 4.2% (1/24) had HeartMate III LVAS. Median time from device placement to outflow graft stenting was 24.0 months [7.8-30.4]. 76.9% of patients (20/26) presented with heart failure. 34.6% (9/26) had outflow graft thrombosis, 34.6% (9/26) stenosis, 11.5% (3/26) kinking, 11.5% (3/26)

BACKGROUND New generation continuous-flow left ventricular assist devices (LVADs) utilise centrifugal pumps. Data concerning their effect on patient haemodynamics, ventricular function and tissue perfusion is limited. We aimed to document these parameters following HeartWare centrifugal continuous-flow LVAD (HVAD) implantation and to assess the impact of post-operative right heart failure (RHF). METHODS We reviewed 53 consecutive patients (mean age 49.5 ± 14.1 yrs) with HVAD implanted in the left ventricle, at St. Vincents Hospital, Sydney, between January 2007 and August 2012. Available paired right heart catheterisation (n=35) and echocardiography (n=39) data was reviewed to assess response of invasive haemodynamics and ventricular function to LVAD support. RESULTS A total of 28 patients (53%) were implanted from interim mechanical circulatory support. Seventeen patients (32%) required short-term post-implant veno-pulmonary artery extracorporeal membrane oxygenation. At 100 ± 61 days ...

This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. The device was effective in unloading the failing left ventricle and in maintaining an adequate systemic circulation. The principles of perioperative monitoring, and pharmacological therapy are outlined. The pump was also used as an alternative to the heart-lung machine in conjunction with coronary artery bypass surgery. Together with a short-acting β-blocker, esmolol, the heart was decompressed and heart motion was reduced, facilitating bypass surgery on the beating heart. The anesthesiological considerations using this method are described.. An implantable left ventricular assist device was used as a bridge to heart transplantation in 10 patients. We were interested in assessing the possibility to establish such a treatment program at a ...

N2 - We report the anesthetic management of patients with dilated cardiomyopathy who underwent left ventricular assist device implantation (LVAD). Anesthesia was induced and maintained with midazolam and fentanyl. Transesophageal echocardiography (TEE) and a PA catheter were useful for hemodynamic monitoring and management of the patients. Furthermore, TEE is useful for the early detection of inflow of the air which is absorbed by negative pressure derived from high LVAD support pressure. On starting LVAD support, evaluation of right ventricular function and treatment for right ventricular failure were important and necessary for the patients. Added to conventional therapy using catecholamines, inhaled nitric oxide may provide a ...

Background: In this study, we aimed to investigate frequency, patterns, etiologies, and costs of unplanned readmissions after left ventricular assist device implantation.. Methods: Between April 2012 and September 2016, 99 unplanned readmissions of a total of 50 consecutive bridge-to-transplant patients (45 males, 5 females; mean age 46.9±10.3 years; range, 19 to 67 years) who were successfully discharged after left ventricular assist device implantation were retrospectively analyzed. Patient demographic data, hemodynamic measurements before implantation, and readmissions after discharge were recorded. Hospitalizations due to major problems which were unable to be managed in routine outpatient clinic were accepted as unplanned readmissions. Survival analysis was performed.. Results: The readmission rate was 1.7 per year after discharge. Survival of patients who were readmitted within the first 90 days was found to be significantly lower than those without early readmission. The most common ...

Methods and results: Our study sought to evaluate the effectiveness of axial- and centrifugal- continuous flow LVADs in reversing PH in heart transplant candidates. Hemodynamics were assessed pre- and post-operatively in nine patients undergoing HeartMate II and six patients undergoing HeartWare continuous flow LVADs. Mean PA pressures were reduced from 31.9 ± 10.6 mm Hg to 22.1 ± 6.6 mm Hg (p = 0.001), and pulmonary vascular resistance was reduced from 3.08 ± 1.6 mm Hg to 1.8 ± 1.0 mm Hg (p = 0.007). This improvement was seen within seven days of LVAD implantation. Three of 15 patients were successfully transplanted, with 100% survival at an average of 199 days post-transplant ...

TY - JOUR. T1 - Current Axial-Flow Devices-the HeartMate II and Jarvik 2000 Left Ventricular Assist Devices. AU - John, Ranjit. PY - 2008/9/1. Y1 - 2008/9/1. N2 - The increased applicability and excellent results with left ventricular assist devices (LVADs) have revolutionized the treatment options available for patients with end-stage heart failure. Until recently, most patients who have undergone LVAD implantation have been supported by pulsatile devices. Unfortunately, the use of the latter devices is associated with significant comorbidity, primarily as a result of their large size and limited durability. The HeartMate II and the Jarvik 2000 pumps, both of which incorporate axial-flow and rotary pump technology represent the next generation of devices. The clinical use of these newer axial-flow pumps have resulted in superior outcomes, including significantly reduced complication rates with improved durability. However, as with all new technology, axial-flow LVADs have also introduced a ...

Although heart transplantation is an effective interventional therapy for end-stage heart failure (HF), donor hearts are consistently in limited supply. Hence, patients who experience clinical deterioration before transplant availability are frequently given mechanical circulatory support in the form of a left ventricular assist device (LVAD), employed as a bridge to transplant. To date, the utility, efficacy, and safety of LVAD support as a bridge to transplant has been widely recognized (1,2). Importantly, LVAD support, similar to all drugs that exert beneficial effects on mortality in patients with HF, also favorably impacts the left ventricular (LV) remodeling process (3-6). Recent evidence has demonstrated that unloading the LV in patients with end-stage HF by LVAD support can lead toward reverse remodeling of myocardial structure and function (6-15). Studies of LVAD-mediated reverse remodeling have described changes such as decreased myocyte size (8,12,14), increased myocyte ...

Approximately two-thirds of patients implanted with ventricular assist devices recover sufficiently to requalify for heart transplantation, and the other one-third die of complications that are often secondary to delayed ventricular assist device implantation and subsequent end-organ failure. To determine whether any preoperative predictors of survival exist, univariate statistics and multivariate stepwise logistic regression analysis were performed on pre-ventricular assist device demographics, hemodynamics, and blood chemistry in 186 patients receiving Thoratec ventricular assist devices (Thoratec Laboratories Corp., Berkeley, Calif.) while awaiting transplantation. The duration of circulatory support averaged 19.6 days (maximum, 226 days). One hundred thirty-seven patients (74%) received biventricular support, 47 received isolated left ventricular assist devices, and two received right ventricular assist devices. The average blood flow was 5.0 +/- 0.9 L/min. One hundred eighteen patients (63%)

ABSTRACT: Objective. We sought to describe the use of the TandemHeart percutaneous left ventricular assist device (PVAD) in a group of high-risk patients undergoing complex cardiovascular procedures. Background. There is a substantial risk of acute decompensation and death in patients with cardiogenic shock or a reduced cardiac reserve undergoing high-risk cardiovascular interventions. The TandemHeart PVAD provides near-total hemodynamic support in this setting. Methods. Thirty-seven high-risk patients underwent placement of the TandemHeart PVAD during 38 separate proc

Background: A continuous flow left ventricular assist device (c-LVAD) provides a better clinical outcome for patients with severe heart failure than pulsatile flow LVAD (p-LAVD). However, the frequency of cerebrovascular events, crucial complications, is largely unknown, especially in patients with systemic infection. We examined the prevalence of stroke related to systemic infection in patients with these 2 LVAD types.. Methods: We reviewed 114 consecutive patients (c-LVAD group: n=47, 66.6 patient-years; p-LVAD group: n=67 patients, 63.5 patient-years) who received LVAD support at Osaka University Hospital from 2005-2012. Cerebrovascular complications were defined as a neurological deficit concomitant with a coinciding lesion shown by computed tomography. Anticoagulation was given according to the manufacturers recommendation. Stroke frequency was compared between the groups.. Results: During LVAD support, 8 patients (c-LVAD, 1; p-LVAD, 7) died from stroke. As for cerebral infarctions, 10 ...

The incorporation of complex medical device technologies into clinical practice is governed by critical oversight of the US Food and Drug Administration. This regulatory process requires a judicious balance between assuring safety and efficacy, while providing efficient review to facilitate access to innovative therapies. Recent contrasting views of the regulatory process have emphasized the difficulties in obtaining an optimal balance. Mechanical circulatory support has evolved to become an important therapy for patients with advanced heart failure with the advent of more durable, implantable ventricular assist devices. The regulatory oversight of these new technologies has been difficult owing to the complexities of these devices, associated adverse event profile, and severity of illness of the intended patient population. Maintaining a regulatory environment to foster efficient introduction of safe and effective technologies is critical to the success of ventricular assist device therapy and ...

Mechanical circulatory support systems, such as continuous-flow left ventricular assist devices (CF-LVADs), are being increasingly used as destination therapy or bridge to heart transplantation in patients with end-stage heart failure. The rate of implantation has nearly doubled since 2010, with ,5,000 devices placed in the last 2 years in the United States alone (2). Despite survival improvement with these devices, the clinical course of the patient is punctuated by a number of adverse events, including residual heart failure, which frequently warrants additional investigations.. Inadequate left ventricular (LV) unloading, often as a consequence of suboptimal left ventricular assist device (LVAD) parameters or comorbidities, is central to the worsening symptoms; some of these events can be treated with simple but effective options (e.g., optimize the device settings, use diuretics). However, other causes, such as right ventricular (RV) failure, can present with heart failure-like symptoms ...

Intramyocardial Injection of Mesenchymal Precursor Cells and Successful Temporary Weaning From Left Ventricular Assist Device Support in Patients With Advanced Heart Failure: A Randomized Clinical Trial.

End-stage heart failure is associated with significant morbidity and mortality. Heart transplantation has the potential to offer a return to daily activities for critically ill patients and is the gold standard therapy. However, heart transplantations are decreasing yearly with a historic low in Germany in 2017. By striking contrast, both waiting list numbers and waiting time have increased owing to a lack of acceptable donor organs. Ventricular assist devices (VAD) represent a reasonable therapeutic alternative for patients on heart transplantation waiting lists. Patients ineligible for transplantation may undergo VAD implantation as a destination therapy. However, the necessity for life-long anticoagulation must be weighed against bleeding complications in potential VAD candidates. VAD-dependent patients also face risks of driveline infections, in addition to restricted activities of daily living owing to limited battery capacities. Given Germanys low transplantation rate, VAD implantation ...

Left ventricular assist devices (LVADs), because of their device routing, can produce thromboembolic showers to the kidney resulting in renal cortical ischemia or infarctions. Although postmortem evaluation of renal pathology can confirm ischemic events and infarctions, there are no validated and highly sensitive real-time measures of renal ischemia in the preclinical models. In this article, we report the evaluation of urinary biomarkers of ischemic tubular damage in a lamb preclinical LVAD model. We found that urinary excretion of glutathione-S-transferase-π, heat shock protein 1B, and hepatitis A virus cellular receptor 1 ...

The heart is a beating muscle that pumps blood to the lungs and body through the circulatory system. Inside the heart are four chambers that are responsible for collecting blood and then redistributing it to the body. The top two chambers are called the right and left atria, and the larger chambers on the bottom are called the right and left ventricles. The left ventricle is responsible for pumping 3 to 6 liters of blood to the entire body every minute. However, disease can sometimes cause failure of the left ventricle to pump enough blood to keep the body functioning normally. In this case, a machine called a left ventricular assist device, or LVAD, can help the heart perform its work. A left ventricular assist device is a mechanical pump-type apparatus that is surgically implanted in the body. It helps maintain the pumping ability of a heart that cannot effectively work on its own. Many of the new LVADs are implanted directly into the left ventricle and propel blood through a tube that is ...

AbstractRight heart failure (RHF), e.g. due to pulmonary hypertension (PH), is a serious health issue with growing occurrence and high mortality rate. Limited efficacy of medication in advanced stages of the disease constitutes the need for mechanical circulatory support of the right ventricle (RV). An essential contribution to the process of developing right ventricular assist devices (RVADs) is the in vitro test bench, which simulates the hemodynamic behavior of the native circulatory system. To model healthy and diseased arterial-pulmonary hemodynamics in adults (mild and severe PH and RHF), a right heart mock circulation loop (MCL) was developed. Incorporating an anatomically shaped silicone RV and a silicone atrium, it not only enables investigations of hemodynamic values but also suction events or the handling of minimal invasive RVADs in an anatomical test environment. Ventricular pressure-volume loops of all simulated conditions as well as pressure and volume waveforms were recorded and compared

New life-saving treatments for Heart failure in clinical trial on Confirmation Trial of the Acorn CorCap Cardiac Support Device (CSD) at the Same Time as Mitral Valve Repair

Click on the title to purchase the article.. Summary:. Over the past decade, continuous-flow rotary pumps have dramatically improved survival for patients with advanced systolic heart failure. Bleeding and thrombosis, however, continue to be the Achilles heel of left ventricular assist device (LVAD) therapy. There is a dynamic and complex interaction between the patient and pump. The net effect of a variety of hematologic derangements, such as hemolysis, high-molecular-weight von Willebrand degradation, platelet activation and diminished pulsatility, is poorly understood. A combination of these factors mediates the common adverse events of gastrointestinal bleeding, device thrombosis and stroke. In this review we incorporate information from translational investigations in LVAD patients to understand how continuous-flow pumps activate the coagulation system and platelets predisposing to thrombosis, while, in parallel, degrade high-molecular-weight von Willebrand factor and trigger abnormal ...

This brief CME publication explores clinical evidence for the use of left ventricular assist devices (LVADs) in patients with advanced heart failure. It also reviews the evolution of LVADs from first-generation to third-generation devices and discusses therapeutic indications and contraindications for LVADs. Additionally, in a short introductory video, a faculty expert discusses approaches for identifying patients who may be candidates for LVADs and the evolving role of these devices in the treatment of advanced heart failure.

We describe the case of a 54-year-old woman with a postinfarction ventricular septal defect (VSD) and ventricular free wall rupture who was stabilized with a percutaneous ventricular assist device (pVAD) to allow for myocardial infarct stabilization.

Also known as: Heart Assist Pump, Heart Pump, and Mechanical Circulatory Support System). Over the last several decades, doctors and researchers have developed a new generation of devices to mechanically assist blood circulation. Some of these devices replace the function of the left ventricle, which is weakened in heart failure patients. Others supplement it rather than replace it. Assist devices are therefore markedly different from their total artificial heart predecessors.. The Jarvik 2000® Ventricular Assist Device is sometimes called a booster pump. Implanted inside the intact biological heart, it aids the left ventricle in ejecting blood. The flow produced by the Jarvik 2000 is synchronized with the heartbeat so that the blood moves in natural pulses. Most heart failure patients retain enough heart function to make this kind of support more reliable and effective - not to mention more comfortable - than that of a total artificial heart or device that produces the total output of a ...

Mechanical circulatory support devices, such as ventricular assist devices and temporary total artificial hearts, can be surgically implanted in people with advanced heart failure to help the hearts pumping function.. But people with advanced heart failure often also suffer from multi-organ dysfunction syndrome, which can lead to death after a device is implanted and is associated with atypical white blood cell activity. When patients and doctors are considering a mechanical assist device, current clinical methods used to predict treatment results have limitations: They do not perform well in very sick patients and they do not use molecular information. That lack of precision in predicting treatment outcomes can complicate the shared decision-making process between patients and their doctors.. Dr. Mario Deng, the studys principal investigator, was also a co-developer of an FDA-approved molecular blood test called AlloMap, which is used to diagnose organ rejection in heart transplant ...

The cardiac assist device includes a sealed tubular housing for externally applying positive and negative relative pressure to a limb in counterpulsation with heart function. The applicator is assembled, in situ, to provide customized fit. It includes a fabric or sponge-like inner layer cut to size and situated around the limb. Initially deformable material is sized, sealed around the inner fabric layer and then secured by straps or the like to form a relatively rigid, non-expandable tubular shell. The shell may include an interior wall composed of a sheet of hard plastic or articulated sections of hard plastic or metal. The interior wall has a plurality of openings to the sealed shell interior. The exterior shell wall is positioned around the interior wall. The shell walls are spaced apart by radially and/or longitudinally extending spacer elements defining a multi-section air flow chamber between the walls. The interior shell wall and spacer elements may be integral. The spacer elements include

The use of femorofemoral bypass grafting is, therefore, recommended in patients with severe ...

Transcutaneous energy transmission systems (TETS) wirelessly transmit power through the skin. TETS is particularly desirable for ventricular assist devices (VAD), which currently require cables through the skin to power the implanted pump. Current implantable TETS systems are not optimized for high power VAD applications. Optimizing the inductive link of the TET system is a multi-parameter problem. Most current techniques to optimize the design simplify the problem by combining parameters leading to sub-optimal solutions. In this paper we present an optimization method using a genetic algorithm to handle a larger set of parameters, which leads to a more optimal design.. ...

Abstract:. Ventricular tachycardia (VT) is one of the major causes of sudden cardiac death (SCD). In general, VT could be managed with antiarrhythmic drugs (AADs) therapy, catheter ablation and implantable cardioverter defibrillators (ICD). While the AADs therapy and catheter ablation have been shown to reduce the recurrence of VT, only the ICD therapy is effective in aborting SCD. The recently published VANISH trial reveals that VT catheter ablation significantly decreases the rate of death, VT storm and appropriate ICD shock comparing with an escalation of AADs therapy for ischemic cardiomyopathy (ICM). However, the mapping strategies and feasibility of VT catheter ablation are often limited by the hemodynamically intolerant VT. Substrate modification strategy and percutaneous left ventricular assist device (pLVAD) are often used to overcome the hemodynamic intolerance. So far there are no large-scale randomized clinical trials comparing different mapping strategies in the setting of ...

Patients who have some remaining heart function but who can no longer live normally may be candidates for ventricular assist devices (VAD), which do not replace the human heart but complement it by taking up much of the function. The first Left Ventricular Assist Device (LVAD) system was created by Domingo Liotta at Baylor College of Medicine in Houston in 1962.[76]. Another VAD, the Kantrowitz CardioVad, designed by Adrian Kantrowitz boosts the native heart by taking up over 50% of its function.[77] Additionally, the VAD can help patients on the wait list for a heart transplant. In a young person, this device could delay the need for a transplant by 10-15 years, or even allow the heart to recover, in which case the VAD can be removed.[77] The artificial heart is powered by a battery that needs to be changed several times while still working. The first heart assist device was approved by the FDA in 1994, and two more received approval in 1998.[78] While the original assist devices emulated the ...

BACKGROUND: The incidence of atrial fibrillation (AF) among patients undergoing left ventricular assist device (LVAD) implantation is high. However, the impact of AF on clinical outcomes has not been clarified. We reviewed our 9-year experience of continuous flow (CF) LVADs to determine the impact of preoperative AF on stroke, device thrombosis, and survival. METHODS: Between March 2006 and May 2015, 231 patients underwent implantation of 240 CF LVADs, 127 (52.9%) as bridge to transplantation and 113 (47.1%) as destination therapy. Effect of AF on postoperative outcomes was assessed by using Kaplan-Meier survival and Cox proportional hazard regression. RESULTS: There were 78 patients (32.5%) with preoperative AF with a mean age of 55.7 ± 11.4 years. A similar incidence of stroke was found in patients with and without AF, 12.8% versus 16.0%, respectively (p = 0.803). Survival was similar, with 1-, 6-, 12-, and 24-month survivals of 96.2%, 91.7%, 84.5%, and 69.2%, respectively, for AF patients, versus 93

The Medical Center is among the nations leaders in the use of LVADs for people with heart failure. Hughes suffered a heart attack in 2001, which was quite a surprise because his blood pressure and cholesterol levels, common indicators of poor heart health, were normal. I bounced back quickly and led a completely normal life. However, over the past few years, he endured a steady decline in heart health. His Olean cardiologist, Henry Storch, M.D., recommended he see specialists at URMCs Program in Heart Failure and Transplantation. Everything was tiring me out and I just didnt have the energy, said Hughes. ...

In the 1970s, technologies for mechanical circulatory support emerged as an alternative to prolong the life of patients who need to replace the native organ. Until now, there are not enough organs available to be transplanted, so the main purpose of these devices is to provide survival to patients. According to American researchers however, mechanical circulatory support was developed as a therapy for end-stage heart failure when heart transplantation was not yet a useful treatment modality (because the introduction of cyclosporine, which has enabled the increasing success of heart transplantation, has occurred only in the 1980s). That means that the mechanical circulatory support was preceding to heart transplantation. In fact, since the first heart-lung machine used in open-heart surgeries, the use of artificial devices changed the death concept (now considered as brain death), which made possible to replace human hearts. More than change the life and death concept, howev. er, the wider ...

Introduction. The use of veno-veno extracorporeal membrane oxygenation (ECMO)* for profound respiratory failure has been shown to improve survival when compared to conventional ventilator management strategies.1 Despite significant increases in utilization, survival for these complex, if not catastrophic, problems has only improved slightly over the years. Similarly, when used to provide both pulmonary and cardiac support, veno-arterial ECMO can be a useful and potentially life-saving therapeutic modality.2 Unfortunately, given the circumstances, randomized trials and standard practices are difficult to obtain. Nevertheless, there is an increasing amount of literature demonstrating the value of extracorporeal support in the setting of high-risk percutaneous coronary intervention (PCI), particularly when associated with acute cardiogenic shock.3. Background. Conceptually, ECMO is quite simple. Venous drainage is obtained either through the large peripheral veins (femoral, internal jugular, ...

Regeneron Pharmaceuticals (Tarrytown, NY), in collaboration with its international partner Bayer HealthCare, has begun two phase 2 trials of the coformulated combination of its anti-VEGF drug Eylea (aflibercept, Regeneron, Tarrytown, NY) with a company-developed angiopoietin 2 (ANG2) ...

Purpose: Screening for anti-HLA antibodies in heart transplantation candidates is complicated by transfusions as well as by the presence of ventricular assist devices (VADs), which have been shown to be an independent risk factor for developing anti-human leukocyte antigen (HLA) antibodies. As a result, these patients require frequent antibody screens to monitor for the development of anti-HLA antibodies following these sensitizing events. The goal of this study is to define the frequency of HLA alloimmunization in patients that have received VADs.. *Methods: We performed a retrospective analysis of heart transplantation candidates at our center who received a VAD from 1/2015-10/2018, had at least one negative antibody screen pre-VAD (median of 13 days pre-VAD), and were screened at least once post-VAD (first screen performed at a median of 26 days post-VAD). Patients were screened an average of four times post-VAD, and screens after transplantation were not included.. *Results: Of the 52 ...

Objectives: Mechanical circulatory support (MCS) is often required to stabilize therapy-refractory cardiogenic shock patients. Left ventricular (LV) unloading by mechanical ventricular support (MVS) via percutaneous devices, such as with Impella® axial pumps, alone or in combination with extracorporeal life support (ECLS, ECMELLA approach), has emerged as a potential clinical breakthrough in the field. While the weaning from MCS is essentially based on the evaluation of circulatory stability of patients, weaning from MVS holds a higher complexity, being dependent on bi-ventricular function and its adaption to load. As a result of this, weaning from MVS is mostly performed in the absence of established algorithms. MVS via Impella is applied in several cardiogenic shock etiologies, such as acute myocardial infarction (support over days) or acute fulminant myocarditis (prolonged support over weeks, PROPELLA). The time point of weaning from Impella in these cohorts of patients remains unclear. We here
