.Guidewire recrossing into the branch through the stent strut is difficult when that branch was injured or occluded after stenting in the true bifurcation lesion. A 72-year-old man with chronic total occlusion in both mid-left anterior descending coronary artery (LAD) and 2nd diagonal branch (D) was admitted to our hospital. We put a 2.25 × 38 mm drug-eluting stent from the LAD to the D with culotte stenting. However, the LAD occluded after stenting. Although we tried to recross, it was impossible because the guidewire migrated subintimal space which was caused by guidewire manipulation. So, we advanced a 2.25 mm balloon catheter on the 1st guidewire which had already been placed outside of the stent in the LAD, and inflated it at bifurcation to compress the subintimal space. Subsequently, we advanced another guidewire through the strut along the surface of the balloon catheter. Immediately after the deflation of the balloon, the guidewire slipped into the distal LAD without resistance. Large branch occlusion after stenting is a serious complication in true bifurcation treatment. Our new bailout technique is effective for recrossing a guidewire into the dissected branch to preserve it. .Percutaneous extraction of a freshly implanted stent is rarely reported, as it requires high technical expertise and accurate selection of instruments to ensure a safe retrieval process. Herein, we report a case of successful snaring of an erroneously deployed stent in the aorto-ostial position using the coaxial snare technique after successful recanalization of a complex right coronary artery chronic total occlusion. .Mural endocarditis is a rare subclass of infective endocarditis (IE) associated with intra-cardiac tumors, prosthesis, valvular vegetation's, or structural abnormalities such as ventricular septal defects. Bacteria classified as HACEK (Haemophilus species, Aggregatibacter actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae) are rare causes of IE found in only 1.3% to 10% of cases. We describe the second reported case of mural endocarditis involving the left ventricle (LV) caused by a Haemophilus species. A young male with no prior intravenous drug use, valvular heart disease, or recent dental work presented with splenic infarcts. H. para-influenza was identified on blood cultures. Cardiac imaging revealed a 1.5 cm LV mass underneath the posterior leaflet of the mitral valve and a large Atrial Septal Defect (ASD). Awaiting surgery, the patient sustained embolic and hemorrhagic cerebral events. The patient underwent debulking of LV mass, ASD closure, and mitral valve repair complicated by post-pericardiotomy syndrome, and he completed six weeks of ceftriaxone therapy. The patient met modified Duke Criteria, but the diagnosis was challenging due to absence of risk factors, sub-acute symptom onset, delayed blood culture growth, and ambiguous characterization of the mass on imaging. .A 70-year-old man with severe interstitial pneumonia attributed to limited cutaneous systemic sclerosis was referred to our institution because of worsening dyspnea. High-resolution computed tomography did not show considerable progression compared with previous images, whereas transthoracic echocardiography showed severe right ventricular dysfunction. Oxygen saturation was decreased to 84% at room air. A blood test showed an increase in the plasma brain natriuretic peptide level (289.4 pg/mL). Right heart catheterization (RHC) showed a remarkably high mean pulmonary arterial pressure (mPAP) of 48 mmHg at room air. A vaso reactivity test using inhaled nitric oxide showed improvement of mPAP, pulmonary vascular resistance (PVR), and partial pressure of arterial oxygen. These findings suggested that the patient responded to pulmonary hypertension (PH)-targeted drugs. We then prescribed tadalafil 10 mg and inhaled iloprost 5 µg six times daily. Three weeks after initiating PH-targeted drugs, RHC indicated hemodynamic improvement similar to hemodynamic changes in the vaso reactivity test (mPAP 28 mmHg; PVR 4.2 W.U.). He was discharged with improved symptoms. Inhaled nitric oxide during RHC might be helpful to consider the treatment strategy when patients have PH comorbid systemic sclerosis and severe interstitial lung disease. .Primary aldosteronism is often associated with heart failure (HF), and is reportedly difficult to treat in some cases. We report a case of severe HF associated with primary aldosteronism. A patient with HF, who was suspected of having primary aldosteronism, was referred to and examined at our hospital. After detailed examination, the patient was diagnosed with exacerbation of HF, and was treated at our department. Catheterization after admission revealed Forrester class IV HF. The patient was treated with catecholamine infusion in combination with medical treatment including mineralocorticoid receptor antagonists. The patient was diagnosed with hypertension due to primary aldosteronism and intractable secondary HF with increased peripheral vascular resistance. An open adrenalectomy was successfully performed under intra-aortic balloon pumping. Right heart catheterization, performed soon thereafter, demonstrated improvement in the patient's blood pressure and hemodynamics. We speculate that the improved cardiac function resulted from a reduction in the vascular resistance, as a consequence of the adrenalectomy. .Multiple congenital heart disease in the small preterm newborn such as severe narrowing of aortic valve and patent ductus arteriosus (PDA) is a therapeutic challenge. We report successful transcatheter antegrade balloon dilatation of the aortic valve and device closure of the PDA in a 1700-gram preterm newborn. click here Meticulous planning and team work aids in such transcatheter intervention. .Sepsis-related myocardial calcification (SRMC) is a life-threatening complication. However, it is a rare entity and its clinical course is not well-understood. A 54-year-old man after bone graft surgery presented with septic shock due to surgical site infection. The initial computed tomography (CT) showed no deposit of calcium in the left ventricle (LV), and echocardiography demonstrated preserved left ventricular ejection fraction (LVEF) of 61%. On the 10th day of admission, CT detected new-onset LV myocardial calcification with preserved LVEF of 60% in echocardiography. On the 63rd day, follow-up CT revealed an increased density of the calcified lesion in the LV, and echocardiography showed a significantly reduced LVEF of 30%. This case report clarified a clinical course of SRMC that the calcium deposit began early after the onset of sepsis and LV systolic function declined subsequently along with the progression of the LV calcification. A serial assessment of CT and echocardiography from the initial stage in sepsis could be helpful for early detection and appropriate management of SRMC patients. Learning objectiveSepsis-related myocardial calcification (SRMC) is under-diagnosed in daily clinical practice because most cases progress silently. By serially assessing computed tomography and echocardiography in patients with sepsis from the initial stage, we can detect SRMC early and follow a change in the calcium in the left ventricle (LV) and LV function.>.Given the rarity of significant first-degree atrioventricular block (AVB) after Occlutech Figulla Flex II atrial septal defect occluder (OFF II, Occlutech International AB, Helsingborg, Sweden) placement, its management and predictors of recovery have not been established. We report a 9-year-old boy who developed significant first-degree AVB a day after OFF II deployment. Thereafter, oral prednisolone was initiated at 1.5 mg/kg/day. On day 2 of steroid treatment, normal sinus rhythm without conduction delays was occasionally observed, while the prolonged PR interval on the exercise stress test was ameliorated. After 5 days of steroid administration, normal sinus rhythm without conduction delays was completely achieved. An increase in the frequency of normal sinus rhythm and the absence of conduction delays on electrocardiogram monitoring and exercise stress test play an important role in predicting recovery from prolonged PR interval. Thus, steroid treatment can be effective and should be considered for patients who develop first-degree AVB after undergoing OFF II placement for transcatheter device closure of atrial septal defect. .Cysticercosis is a parasitic infection that is caused by the tapeworm Taenia solium and is prevalent in Latin America, southern Africa, and parts of Asia. Cysticercosis normally affects the central nervous system, but rare cases of cardiac cysticercosis have been reported in the literature. We report a case of asymptomatic cardiac cysticercosis in a 54-year-old Afro-Brazilian man with a history of hemicolectomy and chemotherapy, who demonstrated characteristic intramyocardial lesions on transthoracic echocardiogram and cardiac magnetic resonance imaging, and responded well to subsequent treatment with albendazole and prednisone. .Nonbacterial thrombotic endocarditis (NBTE) is relatively rare, with an identification rate of 1.6% at autopsy, and is associated with malignancy and systemic lupus erythematosus. Further, bioprosthetic valve NBTE is extremely rare, with only a few reports in the literature. To ensure appropriate treatment, it is essential to differentiate between NBTE from infective endocarditis (IE) as soon as possible, but this is difficult without information regarding underlying disease and sufficient time for careful investigation. Here, we report a case of recurrent NBTE of a bioprosthetic valve the day following surgery based on an initial diagnosis of IE. .Food insecurity is a critical global problem with social and public health consequences. In Brazil, access to adequate food is a fundamental human right guaranteed under the country's Constitution since 2010. As such, the State assumes the distinct and complementary obligations to respect, protect, promote and provide the Right to Adequate Food. The aim of this study is to present actions related to the "provision" dimension that have been developed as part of a network of public infrastructure strategies for food and nutrition security in Brazil. Through an exploratory, analytical literature review, the paper focuses on the operational designs and logistics of three main strategies Food Banks, Community Kitchens, and Popular Restaurants. The Brazilian experience indicates that public actions are necessary, especially considering the urgency for those groups living with hunger and poverty. While similar programs can be found in other countries in South and North America, they are mostly offered by civil society organizations, and have not advanced toward public institutionalization. In fact, private programs are criticized for negating governments' obligation and responsibility in this area. Brazil's experience sheds light on public initiatives in meeting the State's obligations towards the Right to Adequate Food.
