A 78-year-old male, ex-smoker, with a history of hypertension and hyperlipidemia presented with a one-month duration of worsening angina on exertion. Standard 12 L ECG showed sinus rhythm with early repolarization pattern in the anterolateral leads. Coronary angiography showed minor luminal irregularities in the left coronary vessels (Figure 1 A & B) while the RCA showed high grade non-thrombotic 90% lesion in its mid segment (Figure 2A arrow) followed by another high grade 90% stenosis in the RPDA branch (Figure 2B). A small calibre acute marginal branch (AMB) with an 80% ostial stenosis was noted to take off from the diseased mid RCA segment (Figure 2A arrowhead). Ad hoc percutaneous coronary intervention (PCI) of both the RPDA and mid RCA was carried out.

Iatrogenic dissection during PCI represents one of the most fearing complication of interventional cardiology, since abrupt hemodynamic instability and patient compromise may occur related to coronary occlusion. In this emergency situation, different hemodynamic support devices and interventional skills, are needed in order to promptly recover the patient from cardiogenic shock, especially when the left coronary three is involved by the dissection. We report herein two different iatrogenic retrograde, and antegrade dissections, one involving both left anterior descending artery, left circumflex and aortic bulb and the second characterized by abrupt closure of left main associated with severe hemodynamic compromise and ventricular fibrillation storm which required continuous DC shocks, Impella and ECMO devices support to stabilize the patient. Both cases were successfully managed percutaneously. Different techniques and tricks in order to re-open the vessels are described. We conclude that in case of iatrogenic coronary dissection, a “keep calm and carry on” strategy should be adopted by the interventional cardiologist team in order to solve such dramatic complication.

The electrical impedance tomography (EIT) is a bedside monitoring tool that noninvasively visualizes local ventilation and arguably lung perfusion distribution. Is a non-invasive radiation-free monitoring technique that provides images based on tissue electrical conductivity of the chest [1]. Some studies [2,3] including adult patients have applied EIT in the context of the preoperative, intraoperative period, extending to the postoperative follow-up of several clinical situations. However, so far there are no scientific publications in this context in the pediatric age group.

Background: Levosimendan, an inotrope and vasodilator, is a second-line treatment for cardiogenic shock. One of its main advantages is its prolonged effect compared to Dobutamine. Case presentation: Our reports show two cases of successful treatment with levosimendan involving patients presenting in a state of cardiogenic shock with electrical storm, which had never been described before. Levosimendan infusion, with no initial bolus dose, enabled us to correct the low cardiac output in both cases, with no secondary rhythm disturbances. Apart from the absence of any pro-arrhythmic effect, infusion of Levosimendan allowed a double angioplasty to be performed under optimal haemodynamic conditions in the first case; and provided us sufficient time to reflect on implantable cardioverter defibrillator implantation with resynchronization due to its conversion into active metabolites in the second case. Conclusion: Through the neutral effects of levosimendan on heart rhythm and the absence of Myocardial oxygen consumption (MvO2) increasing, these two cases show the feasibility and safety of levosimendan treatment in this indication; and emphasise levosimendan’s lack of pro-arrhythmic effect when used without a bolus dose. its its prolonged effect This discusses two clinical cases of patients to care with shock and treated by Levosimendan. these two cases, we will discuss the absence of a pro-arrhythmic effect.

Posterior reversible encephalopathy syndrome (PRES) is a disorder related to an acute impairment of cerebral flow autoregulation that causes brain hyperperfusion and blood-brain barrier breakdown, leading to vasogenic edema affecting typically the posterior part of the brain usually related to acute severe hypertension [1]. Usual clinical presentation includes headaches, vomiting, encephalopathy, visual blurring and seizures. Diagnosis is confirmed by brain MRI showing vasogenic edema with usually a bilateral parieto-occipital pattern although brain oedema could affect other parts of the brain. Ten years ago, a case of reversible edema of the spinal cord has been reported in a patient with PRES associated to malignant hypertension (PRES-SCI, PRES with spinal cord involvement).

Catheter-induced coronary artery dissection is a rare complication with potentially life-threatening consequences. It has been described in less than 0.1% of patients undergoing coronary angiography [1-3]. Technical reasons (type of catheter, catheter position, deep intubation) as well an anatomical/histological predisposition (ostial disease, vessel orientation, vessel size, type of collagen fibers) contribute to its development [4-7]. Contact between the tip of the catheter and the arterial wall promoting intimal disruption and subsequent penetration of contrast during the injection is the basic substrate for this phenomenon.

Introduction: The combination of non-vascularized iliac crest bone graft and distraction osteogenesis in a second surgical intervention has only been described to achieve alveolar ridge augmentation. This technique is not recommended to treat bone defects of the jaws caused by firearm projectile. Case presentation: 40-year-old woman with a segmental mandibular defect in the mandible body caused by the impact of a firearm projectile at the age of 1 year. The patient developed a severe Class II dentofacial anomaly that required a two-stage treatment; she underwent mandibular reconstruction with free iliac crest bone graft followed by a bilateral mandibular distraction at the level of the iliac crest bone graft. With these interventions, a remarkable improvement of the patient's malformation was achieved. Conclusion: Horizontal distraction of the free iliac crest bone graft is a safe and predictable procedure to treat dentolabial anomalies requiring mandibular reconstruction. This procedure was performed in the patient without complications. Further studies on the effectiveness of this technique are required.

A 13 month-old boy male infant admitted for fever, generalized polymorphous exanthema, hyperemic conjunctivae, and diarrhea. The onset of the disease was approximately 2 weeks before the admission with a generalized polymorphous exanthema for which he received antihistaminic treatment, but after 7 days he associated fever, hyperemic conjunctivae, and diarrhea being admitted in the regional hospital. The fever persisted despite the antibiotic and symptomatic treatment, and therefore he was transferred in our hospital. The clinical exam at the time of admission revealed influenced general status, generalized polymorphous exanthema, hyperemic pharynx, bilateral conjunctivitis, and approximately five diarrheic stools per day. The laboratory tests revealed leukocytosis (27,050/mL), with neutrophilia (19,900/mL), anemia (Hb 6.9 g/dL, Htc 19.7%, MEV 68.6 fL, MEH 24 pg), thrombocytosis (1,111,000/ mL), elevated inflammatory biomarkers (CRP An Abstract Giant coronary artery aneurysms that occur in 0.5 to 1% of patients with Kawasaki disease can be fatal if associated with thrombosis.

His inflammation was not controlled with multiple doses of IVIG, parenteral and oral steroids, or high-dose aspirin, and he finally needed infliximab, a monoclonal antibody against tumor necrosis factor alpha.
