Project description:Abstract Background High-output heart failure (HF) is a form of HF where patients present with a high-output state with low systemic vascular resistance. This report presents the case of high-output HF in a patient with an arteriovenous shunt and no options for oral-administered drugs. Case summary A 70-year-old male with a terminal jejunostomy fully depending on parenteral feeding through a vena saphena magna shunt presented with symptoms of shortness of breath. Echocardiography revealed eccentric hypertrophy with reduced left ventricular ejection fraction (LVEF) and atrial fibrillation with a heart rate of 70–100 b.p.m. Cardiac magnetic resonance imaging, endomyocardial biopsy, and cardiomyopathy lab revealed no cause of HF. High-output HF based on right heart catheterization due to the arteriovenous shunt or related to irregularity due to atrial fibrillation were potential causes. As a result of his malfunctioning gastrointestinal system, the pharmacological options were limited. He was treated with captopril sublingual, initially 6.25 mg three times daily (TID) and later 12.5 mg TID, which reduced blood pressure. Electrical cardioversion to sinus rhythm was successful but did not improve LVEF. Therefore, the patient was opted for surgically reducing the blood flow through the shunt, resulting in normalization of LVEF. Discussion High-output HF is an uncommon form of HF with an uncertain prevalence. The most common aetiologies reported in the literature are obesity, cirrhosis, and arteriovenous shunts. Sublingual administration of captopril can be an effective treatment option for HF patients unable to absorb oral-administered drugs.

Project description:An autopsy case of Parkes-Weber syndrome presenting high-output heart failure in a patient who died at 52 years old, is reported. The patient had a tumor in the right buttock since childhood, that had grown up to a diameter of 40 cm diameter by the age of 43 years when he felt exertional dyspnea and was diagnosed as having high-output heart failure due to arteriovenous fistulas. Embolotherapy was attempted, which relieved the symptoms. After 4 years his heart failure deteriorated. We performed embolotherapy but his condition did not improve. He died 1.5 years later. The autopsy revealed the weight of the heart was 1040 g with abundant subendocardial and interstitial fibrosis. In this patient, the level of output had been over 16 L/min which lasted for nine years. The left ventricular ejection fraction (LVEF) decreased during the first five years. Each embolotherapy reduced the cardiac output (CO), which was achieved by a large decrease in heart rate (HR) and a small increase in stroke volume (SV) i.e. CO = HR × SV, and was reflected in the increase in LVEF.Learning objectives•Parkes-Weber syndrome has occasionally extensive arteriovenous fistulas in the pelvis that show high-output heart failure.•Treatment of such cases is difficult, but embolotherapy has partial effects on improving hemodynamics.•A long-term high-output state induces interstitial myocardial fibrosis and collagenous subendocardial thickening.

Project description:Iatrogenic complications may manifest in a variety of ways. We present the case of an 86-year-old woman who underwent a percutaneous coronary intervention with a drug-eluting stent for non-ST-segment elevation myocardial infarction followed by leadless pacemaker placement through a femoral approach. Her post-procedure course was complicated by new onset high-output heart failure secondary to iatrogenic arteriovenous fistula formation, requiring covered stent placement.

Project description:AimsPatients with high-flow arteriovenous (AV) access are at risk of developing high-output cardiac failure (HOCF) and subsequent hospitalization. However, diagnosing HOCF is challenging and often requires invasive procedures. The role of systemic vascular resistance (SVR) in diagnosing HOCF is underestimated, and its predictive value is limited. Our study aims to identify non-invasive risk factors for HOCF to facilitate early diagnosis and timely surgical interventions.Methods and resultsWe included 109 patients with high-flow AV access who underwent serial echocardiography. The retrospective cohort was divided into two groups based on their hospitalization due to HOCF. The two groups were matched for age and gender. After a mean follow-up of 25.1 months, 19 patients (17.4%) were hospitalized due to HOCF. The two groups had similar baseline characteristics. However, the HOCF group had a higher value of vascular access blood flow (Qa) (2168 ± 856 vs. 1828 ± 617 mL/min; P = 0.045). Echocardiographic analysis revealed that the HOCF group had more pronounced left ventricular diastolic dysfunction (E/e': 21.1 ± 7.3 vs. 16.2 ± 5.9; P = 0.002), more severe pulmonary hypertension (right ventricular systolic pressure: 41.4 ± 16.7 vs. 32.2 ± 12.8; P = 0.009), a higher Doppler-derived cardiac index (CI) (4.3 ± 0.8 vs. 3.7 ± 1.1; P = 0.031), and a lower Doppler-derived estimated SVR (eSVR) value (5.5 ± 0.3 vs. 6.9 ± 0.2; P = 0.002) than the non-HOCF group. Using multivariable Cox regression analysis, a low eSVR value (<6) emerged as an independent predictor of HOCF hospitalization with a hazard ratio of 9.084 (95% confidence interval, 2.33-35.39; P = 0.001). Receiver operating characteristic curve analysis indicated that CI/eSVR values more accurately predicted HOCF hospitalization [sensitivity: 94.7%, specificity: 51.0%, area under the curve (AUC): 0.75, P < 0.001] than the Qa/cardiac output ratio (AUC: 0.50, P = 0.955), Qa values ≥ 2000 mL/min (AUC: 0.60, P = 0.181), and Qa values indexed for height in metres (AUC: 0.65, P = 0.040).ConclusionsIn patients with high-flow AV access, low eSVR values obtained through non-invasive Doppler echocardiography were associated with a high rate of HOCF hospitalizations. Therefore, routine eSVR screening in these patients might expedite the diagnosis of HOCF.

Project description:We present the case of a 63-year-old woman presenting with a huge pelvic and retroperitoneal high flow arteriovenous malformation (AVM) causing high-output heart failure, who was treated with combined therapies, including transarterial embolization with n-butyl cyanoacrylate-iodized oil mixture (NBCA-lip) and coils for the right ovarian, both internal iliac, 3rd and 4th lumber arteries, venous sclerotherapy using coils and ethanolamine oleate (EO) for the right ovarian and both internal iliac veins with balloon-occluded retrograde transvenous obliteration technique, and direct percutaneous sclerotherapy using the NBCA-lip and EO for the large nidus of AVM under outflow control using occlusion balloon catheters. <Learning objective: Huge arteriovenous fistulae or malformation (AVF/M) are potentially life threatening due to the potential for spontaneous hemorrhaging and high-output heart failure and are notoriously difficult to diagnose and treat. To improve the high-output heart failure, intensive and invasive combined treatments for huge AVF/M are needed including transarterial and transvenous embolization and sclerotherapy and percutaneous nidus sclerotherapy.>.

Project description:BackgroundSevere right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation increases morbidity and mortality. We investigated the association between intraoperative right heart hemodynamic data, echocardiographic parameters, and severe versus nonsevere RVF.MethodsA review of LVAD patients between March 2013 and March 2016 was performed. Severe RVF was defined by the need for a right ventricular mechanical support device, inotropic, and/or inhaled pulmonary vasodilator requirements for >14 days. From a chart review, the right ventricular failure risk score was calculated and right heart hemodynamic data were collected. Pulmonary artery pulsatility index (PAPi) [(pulmonary artery systolic pressure - pulmonary artery diastolic pressure)/central venous pressure (CVP)] was calculated for 2 periods: (1) 30 minutes before cardiopulmonary bypass (CPB) and (2) after chest closure. Echocardiographic data were recorded pre-CPB and post-CPB by a blinded reviewer. Univariate logistic regression models were used to examine the performance of hemodynamic and echocardiographic metrics.ResultsA total of 110 LVAD patients were identified. Twenty-five did not meet criteria for RVF. Of the remaining 85 patients, 28 (33%) met criteria for severe RVF. Hemodynamic factors associated with severe RVF included: higher CVP values after chest closure (18 ± 9 vs 13 ± 5 mm Hg; P = .0008) in addition to lower PAPi pre-CPB (1.2 ± 0.6 vs 1.7 ± 1.0; P = .04) and after chest closure (0.9 ± 0.5 vs 1.5 ± 0.8; P = .0008). Post-CPB echocardiographic findings associated with severe RVF included: larger right atrial diameter major axis (5.4 ± 0.9 vs 4.9 ± 1.0 cm; P = .03), larger right ventricle end-systolic area (22.6 ± 8.4 vs 18.5 ± 7.9 cm; P = .03), lower fractional area of change (20.2 ± 10.8 vs 25.9 ± 12.6; P = .04), and lower tricuspid annular plane systolic excursion (0.9 ± 0.2 vs 1.1 ± 0.3 cm; P = .008). Right ventricular failure risk score was not a significant predictor of severe RVF. Post-chest closure CVP and post-chest closure PAPi discriminated severe from nonsevere RVF better than other variables measured, each with an area under the curve of 0.75 (95% CI, 0.64-0.86).ConclusionsPost-chest closure values of CVP and PAPi were significantly associated with severe RVF. Echocardiographic assessment of RV function post-CPB was weakly associated with severe RVF.

Project description:BackgroundPrimary plasma cell leukaemia is rarely associated with high-output heart failure, and the underlying mechanism is not well understood. We encountered a rare case of high-output heart failure caused by primary plasma cell leukaemia. Its underlying mechanism was clarified through imaging studies.Case summaryA 49-year-old man with no specific medical history was admitted to our hospital because of heart failure that did not improve with diuretic therapy. His condition was diagnosed as high-output heart failure and primary plasma cell leukaemia after admission. Extensive bone involvement in primary plasma cell leukaemia and arteriovenous shunts in the same lesion were suspected after various imaging studies. The first cycle of chemotherapy with bortezomib, adriamycin, and dexamethasone led to remission of primary plasma cell leukaemia and improved heart failure symptoms. The patient received further chemotherapy in addition to autologous peripheral blood stem cell transplantation and maintenance therapy and had no recurrence of pPCL or heart failure for 1 year to date.DiscussionPrimary plasma cell leukaemia can be associated with high-output heart failure, which is caused by arteriovenous shunting at the lesion site with diffuse bone involvement. Imaging studies may lead to the early diagnosis of aetiology and treatment of patients with high-output heart failure associated with primary plasma cell leukaemia.
