The purpose of this case report is to describe the multimodal cardiac magnetic resonance (CMR) imaging features of an invasive thymoma extending into the superior vena cava and right atrium. This unusual case indicates that multimodal CMR can not only reveal the morphological features of thymoma but also enable the identification of histological types, which provides a reasonable surgical plan in the perioperative management. .We report a case of pulmonary embolism while performing pacemaker implantation in an obese patient and its management as well as certain precautions that one must consider in an obese patient especially under conscious sedation. Air embolism during pacemaker implantation although rare can be life-threatening in certain conditions such as massive pulmonary embolism. Air embolism during this procedure mainly occurs through open sheath just before inserting the lead. Certain risk factors associated with this condition include deep inspiration, frequent coughing, advanced age, sheath with larger diameter, and sedatives. Obesity along with associated factors including sleep apnea, restrictive lung disease, and challenges during airway management can create troubles during pacemaker implantation. Conscious sedation is usually required when a patient becomes restless during the procedure either due to pain or prolonged supine position. At times a patient can transiently go into the deep sedation and a deep inspiration during this phase can be detrimental in a procedure where it is undesirable and adds to the risk of air embolism. Here we discuss the management and alternative methods which can be used to avoid such complications. .We report a correlation between trends of hemodynamic parameters including pulmonary artery pressures (PAP) and heart rate recorded by CardioMEMS device (St. Jude Medical, St. Paul, MN, USA) and presentation of gastrointestinal (GI) bleeding in two patients with left ventricular assist devices. We observed a decline in PAP levels prior to symptom onset and reduction in hemoglobin level in both patients. https://www.selleckchem.com/products/sodium-palmitate.html Early recognition of hemodynamic changes by CardioMEMS device might help clinicians to detect the preclinical phase of GI bleeding and intervene before patients develop severe symptoms and associated morbidity. .The development of angina in the setting of new-onset left bundle branch block (LBBB) that resolves at the same time with the disappearance of LBBB, without coexistent myocardial ischemia, denotes the painful LBBB syndrome. In this illustrative case report we describe a young male patient with painful LBBB syndrome. The LBBB was rate-dependent occurring during exercise and the patient was successfully treated with bisoprolol. We also provide a concise review of the literature and we briefly discuss the diagnosis and management of this clinical entity. .Left main coronary artery (LMCA) injury is an uncommon complication of catheter ablation. Due to the large myocardial area at risk, its presentation is usually acute with a dramatic course and life-threatening sequelae. Increased susceptibility to spontaneous coronary artery dissection has recently been implied in patients with bicuspid aortic valve (BAV). We present the first case of iatrogenic coronary dissection in a BAV patient, with an atypically delayed manifestation. The patient sustained ablation catheter-induced mechanical damage of LMCA due to its inadvertent penetration during the attempts to cross the aortic valve. After three days of recurring chest pain, he was readmitted with anterior myocardial infarction and imminent cardiogenic shock, and underwent emergent coronary stenting. Literature review suggests that in BAV inherent susceptibility to both spontaneous and iatrogenic coronary dissection may exist. Therefore, we advocate that in BAV extreme caution should be exercised during electrophysiological procedures involving the coronary artery cannulation for tagging or pace mapping, or when the left ventricle is to be entered retrogradely, and likewise in percutaneous coronary interventions. Such patients may be doubly predisposed to iatrogenic injury; firstly, by more difficult catheter manipulation in the malformed aortic cusps, and secondly, by the underlying vulnerability of coronary ostia. .Fetuses with congenital long QT syndrome (LQTS) may experience life-threatening arrhythmias, such as torsade de pointes (TdP), and/or functional atrioventricular block. However, trans-maternal pharmacotherapy for these cases is rarely reported and management practices have yet to be established. The fetus of a mother with genetically-confirmed LQTS type 2 (LQT2) presented with complex arrhythmias, diagnosed via magnetocardiography as ventricular arrhythmias (including TdP), at 28 weeks of gestation. After initiation of trans-maternal nadolol administration at 15 mg/d initial dosage and 30 mg/d subsequent dosage, the frequency of fetal ventricular arrhythmias decreased and almost disappeared within several days. The mother gave birth to the baby at full term without significant complications in either the mother or fetus. This is the first report that demonstrates the efficacy and safety of trans-maternal administration of nadolol for treatment of symptomatic LQT2 fetuses with TdP. .Congenital long QT syndrome (LQTS) is associated with ventricular arrhythmia and an increased risk of sudden cardiac death in young people. However, it is extremely rare for an elderly man to experience ventricular fibrillation (VF) due to congenital LQTS as a first episode. We describe the case of an 84-year-old man who experienced syncope after urination. He had a medical history of hypertension and asthma, but no history of syncope. Electrocardiographic findings in 2017 showed QT prolongation (corrected QT = 505 ms). No medication that could induce QT prolongation was administered. Blood test results on admission showed no electrolyte abnormalities, and there were no abnormal findings on echocardiography. The second episode of loss of consciousness occurred during hospitalization, and electrocardiography revealed incessant torsade de pointes, caused by R-on-T with short-long-short (SLS) sequences due to bradyarrhythmia. Coronary angiography did not detect myocardial ischemia, and an implantable cardioverter-defibrillator was implanted for secondary prevention.
