Successful CTO PCI is associated with reduced long-term cardiac mortality and need for coronary artery bypass graft surgery. Treatment of CTO with DES rather than BMS is associated with a significant reduction in target vessel revascularization with similar rates of stent thrombosis. Paclitaxel-eluting stents and sirolimus-eluting stents had similar long-term safety and efficacy outcomes.

Patient: Male, 33Final Diagnosis: Perimyocarditis associated with drug reaction with eosinophilia and systemic symptoms syndromeSymptoms: Skin rashMedication: —Clinical Procedure: —Specialty: DermatologyObjective:Rare diseaseBackground:Drug reaction with eosinophilia and systemic symptoms (DRESS) is a clinical syndrome that can be life-threatening, depending on the organs involved. Although DRESS commonly presents with skin lesions, myocarditis and pericarditis associated with DRESS, although rare, can be fatal. A case of DRESS associated with myocarditis is presented with a review of the literature of 43 reported cases of DRESS associated with myocarditis that included the present case, to evaluate the effectiveness of treatment of DRESS with corticosteroids.Case Report:A 33-year-old man presented with fever, diarrhea, and a diffuse maculopapular rash, four weeks after being treated with antibiotics and a nonsteroidal anti-inflammatory drug (NSAID). He developed renal failure, liver dysfunction, and profound hypotension with severe left ventricular dysfunction that required mechanical cardiac support. A diagnosis was made of myocarditis associated with DRESS syndrome. After treatment began with prednisolone, the skin rash, multi-organ dysfunction, and cardiogenic dysfunction resolved.Conclusions:Myocarditis is a rare complication associated with DRESS, but when it is suspected, urgent echocardiography should be performed, particularly when hemodynamic instability occurs. Early diagnosis, removal of the causative agent, and treatment with corticosteroids are important to reduce mortality from cardiac involvement in patients with DRESS.

Background: Accurate, non-invasive diagnosis of, and screening for, coronary artery disease (CAD) and restenosis after coronary revascularization has been a challenge due to either low sensitivity/specificity or relevant morbidity associated with current diagnostic modalities.Methods: To assess sensitivity and specificity of a new computerized, multiphase, resting electrocardiogram analysis device (MultiFunction-CardioGramsm or MCG a.k.a. 3DMP) for the detection of relevant coronary stenosis (>70%), a meta-analysis of three published prospective trials performed in the US on patient data collected using the US manufactured device and analyzed using the US-based software and New York data analysis center from patients in the US, Germany, and Asia was completed. A total of 1076 patients from the three trials (US - 136; Germany - 751; Asia - 189) (average age 62 ± 11.5, 65 for women, 60 for men) scheduled for coronary angiography, were included in the analysis. Patients enrolled in the trials may or may not have had prior angiography and/or coronary intervention. Angiographic results in all studies were classified for hemodynamically relevant stenosis (> 70%) by two US based angiographers independently.Results: Hemodynamically relevant stenosis was diagnosed in 467 patients (43.4%). The device, after performing a frequency-domain, computational analysis of the resting ECG leads and computer-database comparison, calculated a coronary ischemia “severity” score from 0 to 20 for each patient. The severity score was significantly higher for patients with relevant coronary stenosis (5.4 ± 1.8 vs. 1.7 ± 2.1). The study device (using a cut-off score for relevant stenosis of 4.0) correctly classified 941 of the 1076 patients with or without relevant stenosis (sensitivity-91.2%; specificity-84.6%; NPV 0.942, PPV 0.777). Adjusted positive and negative predictive values (PPV and NPV) were 81.9% and 92.6%, respectively (ROC AUC = 0.881 [95% CI: 0.860-0.903]). Subgroup analysis showed no significant influence of sex, age, race/nationality, previous revascularization procedures, resting ECG morphology, or participating center on the device's diagnostic performance.Conclusions: The new computerized, multiphase, resting ECG analysis device (MultiFunction-CardioGramsm) has been shown in this meta-analysis to safely and accurately identify patients with relevant coronary stenosis (>70%) with high sensitivity and specificity and high negative predictive value. Its potential use in the evaluation of symptomatic patients suspected to suffer from coronary disease/ischemia is discussed.

For aortic annular measurements using 3D TEE in AS patients, semi-automated analysis using the novel automated software reduced analytical time while maintaining similar accuracy compared to the conventional cross-sectional analysis. This automated software may have acceptable feasibility in the clinical setting.
