Infected thoracic aortic graft in a woman with Darier disease: a case report.

Background: Patients with Darier disease often present with staphylococcal skin infections and are at risk for complications when they undergo cardiothoracic surgery, such as acute aortic dissection repair. Case summary: A 39-year-old woman with hypertension and Darier disease suffered an acute type A aortic dissection, requiring emergency operation with a Dacron graft. Twenty-five days post-operatively, she developed pneumonia and staph hominis was isolated in blood cultures and Bronchoalveolar Lavage. Following completion of antibiotics, multiple relapses occurred during a 6-month period, each time treated with appropriate antibiotic therapy. An 18F-fluorodeoxyglucose positron emission tomography computerized tomography showed persistent graft uptake and re-operation was performed. At 22 months of follow-up, the patient remains asymptomatic and the 18F-FDG PET/CT shows significant reduction in FDG uptake. Discussion: Graft infection is a rare but serious complication. Antibiotic therapy is often inadequate and re-operation is needed. As staphylococcal skin infections often occur in patients with Darier disease, adequate preprocedural skin preparation and sterilization are very important in these patients.

A case report of fulminant primary streptococcal pericarditis.

BACKGROUND: Bacterial pericarditis is a rare, rapidly progressive, and highly fatal infection, even with drainage and antibiotics. Gram-positive cocci, specifically Streptococcus pneumoniae, have been the most common cause of bacterial pericarditis from either haematogenous dissemination, or spread from another adjacent site of infection. Following the introduction of antibiotics in the 1940s and more recently the pneumococcal conjugate vaccine, the incidence has drastically decreased. CASE SUMMARY: A previously healthy young male was diagnosed with acute pericarditis with no signs of haemodynamic compromise on initial presentation. Several hours later, he became unstable suffering from cardiac tamponade and septic shock. Despite urgent pericardiocentesis and drainage of purulent fluid, culture positive for streptococcus pneumoniae, multi-organ failure was eventually fatal. DISCUSSION: We describe a rare case of primary S. pneumoniae purulent pericarditis leading to tamponade, septic shock, and death. Due to the high mortality rate of purulent pericarditis, a high index of suspicion is needed in order to initiate appropriate therapy with antibiotics and drainage.

Permanent Sinus Node Arrest Complicating Coronary Angioplasty.

Sinus node artery (SNA) occlusion is a rare complication of percutaneous coronary intervention and usually has a benign prognosis; sinus arrest may occur but frequently resolves. We report a case of unresolved SNA obstruction following percutaneous coronary intervention of the mid-right coronary artery, for which permanent pacemaker implantation was required. (Level of Difficulty: Beginner.).

Multiple myocardial bridges causing severe ischaemia in adolescent with pulmonary stenosis.

Myocardial bridges are often asymptomatic but may need therapy when causing ischaemia. They have rarely been reported in children or in association with CHD, where symptomatology may be mistakenly attributed to the CHD. We report a case of multiple myocardial bridges causing ischaemia in an adolescent with pulmonary stenosis and discuss management.

68-year-old woman with paroxysmal atrial fibrillation.

We present the case of a 68-year-old woman, currently asymptomatic but with a history of paroxysmal atrial fibrillation and tachycardia-bradycardia syndrome, for which she underwent a DDD pacemaker implantation and was started on oral anticoagulants. A recent chest X-ray (figure 1), for respiratory infection, was performed and the patient was referred to our institution for evaluation. Following diagnostic procedures, the patient was successfully operated on. heartjnl;105/8/656/F1F1F1Figure 1Preoperative chest X-ray (A) and chest CT with contrast (B).

Platelet to lymphocyte ratio in acute aortic dissection.

BACKGROUND: Inflammation plays an important role in the initiation and progression of acute aortic dissection (AAD). New inflammatory indices derived from full cell blood count and its differential may be associated with increased risk. We evaluated platelet-lymphocyte (PLR), red cell distribution width (RDW) and RDW/PLT's (platelets) (RPR) in AAD. METHODS: We studied 120 consecutive patients with AAD type I admitted for emergency surgery (group I), 121 consecutive patients with aortic aneurysms of the ascending aorta prior to elective repair (group II) and 121 controls (group III), age and sex matched. RESULTS: PLR was significantly higher in group I vs both groups II and III (P < .001). There was an excellent correlation of PLR with neutrophil/lymphocyte ratio (NLR) in all three groups (P < .001 for all). After adjustment for hemoglobin, RDW did not differ but RPR remained significantly higher in group I compared to groups II and III (P < .001). The best cutoff value of PLR to predict dissection was 159 with 53% sensitivity and 86% specificity. No association between PLR, RDW, and RPR and mortality in group I was found. CONCLUSIONS: Indices derived from full cell blood count may provide diagnostic information in patients with AAD; whether these indices may contribute to prognosis assessment should be further investigated.

Dyspnoea on exertion in a 53-year-old woman.

CLINICAL INTRODUCTION: A 53-year-old woman with no previous medical history complained of easy fatigue over the last 6 months. She had a positive family history for coronary artery disease but no other risk factors. On physical examination, a 3/6 pansystolic murmur was heard over the apex, and the lung auscultation was unremarkable. Her ECG showed a left anterior fascicular block, with poor R wave progression in the anterior leads (see online supplementary image A). A subsequent echocardiogram revealed a slightly dilated for the patient's body surface area (BSA) (1.73 m2) left ventricle (55/35 mm), with preserved systolic function and a moderate functional mitral regurgitation. The estimated pulmonary artery pressure was 45 mm Hg. During treadmill radionuclide scintigraphy, her exercise tolerance was normal, with good inotropic response, and 96% oxygen saturation at rest and at peak exercise. A 2 mm ST segment depression was noted at peak effort, which persisted well into recovery (see online supplementary image B). The scintigraphy scan showed extensive reversible anteroapical wall ischaemia (see online supplementary image C). At this point she was referred to us for right and left heart catheterisation. Intracardiac pressures and saturations were: right atrium (RA)RA=3 mm Hg, right ventricle (RV)=26/3 mm Hg, Pulmonary artery (PA)=26/10/mean 16 mm Hg, pulmonary capillary wedge pressure (PCWP)=11 mm Hg, left ventricle (LV)=110/10 mm Hg, Aorta (Ao)=110/60/mean 80 mm Hg, Superior vena cava saturation (SVCsat)=62%, RAsat=62%, PAsat=78%, Aosat=96% and estimated pulmonary to systematic flow ratio (Qp/Qs)=1.8. Her coronary angiography and CT angiography are shown in figure 1A,B.DC1SP110.1136/heartjnl-2017-311256.supp1Supplementary material 1 DC2SP210.1136/heartjnl-2017-311256.supp2Supplementary material 2 DC3SP310.1136/heartjnl-2017-311256.supp3Supplementary material 3 heartjnl;103/17/1390/F1F1F1Figure 1Coronary and CT angiograms.

Osteopontin in relation to Prognosis following Coronary Artery Bypass Graft Surgery.

Cardiovascular events may occur even after complete revascularization in patients with coronary artery disease. We measured preoperative osteopontin (OPN) levels in 131 consecutive patients (66.5 ± 10 years old, 117 men and 14 women) with left ventricular ejection fraction of 50.7 ± 9.2% and low logistic EuroScore (3.5 ± 3.2%) undergoing elective Coronary Artery Bypass Grafting (CABG) surgery. Patients were prospectively followed up for a median of 12 months (range 11-24). The primary study endpoint was the composite of cardiovascular death, nonfatal myocardial infarction, need for repeat revascularization, and hospitalization for cardiovascular events. Pre-op OPN plasma levels were 77.9 (49.5, 150.9). Patients with prior acute myocardial infarction (AMI) had significantly higher OPN levels compared to those without [131.5 (52.2, 219) versus 73.3 (45.1, 125), p = 0.007]. OPN levels were positively related to EuroScore (r = 0.2, p = 0.031). Pre-op OPN levels did not differ between patients who had a major adverse event during follow-up compared to those with no event (p = 0.209) and had no effect on the hazard of future adverse cardiac events [HR (95% CI): 1.48 (0.43-4.99), p = 0.527]. The history of AMI was associated with increased risk of subsequent cardiovascular events at follow-up (p = 0.02). OPN is associated with preoperative risk assessment prior to low-risk CABG but did not independently predict outcome.

Four-year clinical results of transcatheter self-expanding Medtronic CoreValve implantation in high-risk patients with severe aortic stenosis.

BACKGROUND: transcatheter aortic valve implantation (TAVI) has emerged as an alternative to surgical aortic valve replacement for patients with severe aortic stenosis considered inoperable or at high operative risk, but the long-term outcome remains unknown. HYPOTHESIS: we assessed the 4-year clinical and echocardiographic outcomes of patients undergoing TAVI with the self-expanding Medtronic CoreValve prosthesis. METHODS: sixty-three patients (mean age 80 ± 6 years) with severe aortic stenosis (AS) at high risk for surgical aortic valve replacement (Logistic EuroSCORE 28.8 ± 10.9%) were included in this study. RESULTS: all-cause cumulative mortality at 1, 2, 3 and 4 years was 14.3, 25.4, 28.6 and 36.5%, respectively. The cumulative incidence of documented major stroke at 4 years was 6.3%. In survivors, there was a significant improvement in functional status at 4 years. Paravalvular leak (trivial/mild to moderate) was observed in the majority of patients post-TAVI with no case of progression to severe regurgitation at 4-year follow-up. In multivariate analysis, independent predictor for increased all-cause mortality was left ventricular ejection fraction <40% (HR: 5.347, 95% CI: 1.126-25.381, P = 0.035). CONCLUSION: our study demonstrated favourable long-term (4 years) outcomes after successful TAVI using the third-generation Medtronic CoreValve device.

Prognostic performance of critical care scores in patients undergoing transcatheter aortic valve implantation.

BACKGROUND: Critical care management of patients undergoing transcatheter aortic valve implantation (TAVI) is a major determinant of their outcome. AIMS: The aim of this study was to compare the prognostic performance of four general scoring systems [Acute Physiology and Chronic Health Evaluation (APACHE), Simplified Acute Physiology Score (SAPS), Sequential Organ Failure Assessment (SOFA), and MultiOrgan Dysfunction (MOD) scores] in TAVI patients. METHODS: Between 1 June 2008 and 30 June 2014, 75 patients (81.2 ± 6.4 years old, 36 men and 39 women) who underwent TAVI were scored during the first 24 h of their stay at the intensive care unit (ICU). The outcome measures were in-hospital and 30-day mortality and in-hospital and 30-day morbidity defined as myocardial infarction, implantation of permanent pacemaker, stroke, tamponade, major bleeding, vascular access site complications and prolonged ventilation. RESULTS: Four patients (5.3%) died in ICU and one more during follow-up, indicating a 30-day mortality rate of 6.6%. Regarding in-hospital mortality, the area under the ROC curve (AUC) was 0.92 for SAPS II, 0.88 for APACHE II, 0.73 for MODS and 0.74 for SOFA. Regarding 30 day-mortality, SAPS II and APACHE II performed equally higher (AUC = 0.88) than the other two scores (0.79 for MODS and 0.80 for SOFA). SAPS II had the best calibration among all four scores for in-hospital and 30-day mortality (χ2 = 3.06 and χ2 = 3.29, respectively). AUCs for in-hospital and 30-day morbidity were above 0.7 for SAPS II and APACHE II. CONCLUSIONS: SAPS II and APACHE II are reliable mortality and morbidity risk stratification models for TAVI patients with high calibration and discrimination.

High neutrophil to lymphocyte ratio in type A acute aortic dissection facilitates diagnosis and predicts worse outcome.

OBJECTIVE: The authors investigated whether neutrophil to lymphocyte ratio (N/L) can contribute to the diagnosis and risk assessment in patients with type A acute aortic dissection (AAD). METHODS: The authors studied 120 consecutive patients with type A AAD (group I) and compared them with 121 consecutive patients with chronic aneurysms (group II) and 121 age- and sex-matched healthy subjects (group III). RESULT: It was found that white blood cell count, N/L, D-dimer and C-reactive protein were significantly higher in group I versus both groups II and III (p < 0.001 for all comparisons). White blood cell count and D-dimer were much higher in patients who died compared to survivors in group I (p = 0.023 and p = 0.033, respectively). A cutoff value of N/L >4.6 was associated with 0.89 sensitivity and 0.91 specificity for AAD. CONCLUSION: High N/L may contribute to the diagnostic evaluation and prompt immediate therapy in patients with type A AAD.

Heart rate and B-blockade in stable coronary artery disease in Greece.

INTRODUCTION: Heart rate (HR) is a strong prognostic indicator in patients with coronary artery disease (CAD). However, there is only limited evidence on HR and the use of b-blockers in patients with CAD in contemporary clinical practice. METHODS: CLARIFY is an international, prospective, observational, longitudinal registry of outpatients with stable CAD, defined as prior myocardial infarction or revascularization procedure, evidence of coronary stenosis >50%, or chest pain associated with proven myocardial ischemia. A total of 33,283 patients from 45 countries were enrolled between November 2009 and July 2010; of these, 559 patients were enrolled in Greece (age 62.3 ± 10.6 years, 84.44% men). RESULTS: HR measured by pulse was 68.3 ± 10.2 bpm and by electrocardiogram 67.6 ± 10.9, with an excellent correlation (r=0.91, p<0.001). Overall, 42.8% had HR70 bpm. B-blockers were prescribed in 74.2% of patients. Resting HR by pulse on b-blocker was 67.8 bpm and without b-blocker 69.6 bpm (p=0.069). HR70 bpm was independently associated with a lack of physical activity, higher systolic blood pressure, and a higher prevalence of asthma or chronic obstructive pulmonary disease and carotid artery disease. CONCLUSION: Despite the use of HR lowering agents, the percentage of patients with HR70 bpm was high. It is likely that we can further improve HR control in Greek patients with stable CAD by both increasing the prescription of b-blockers and up-titrating their dose, as well as by using and up-titrating other available HR lowering agents.

Clinical presentation and management of stable coronary artery disease: insights from the international prospective CLARIFY registry - results from the Greek national cohort.

INTRODUCTION: Coronary artery disease (CAD) is highly prevalent worldwide, yet there is a paucity of data regarding the clinical characteristics and management of outpatients with stable CAD. In this paper, we report the baseline data of the Greek cohort and we compare our national data with the global results of the entire registry, as well as the results from the western European countries. METHODS: CLARIFY is an international, prospective, observational, longitudinal registry of outpatients with stable CAD, defined as prior myocardial infarction or revascularization procedure, evidence of coronary stenosis >50%, or chest pain associated with proven myocardial ischemia. A total of 33,283 patients from 45 countries in 4 continents were enrolled between November 2009 and July 2010; of these, 14,726 were from western European countries (Austria, Belgium, Denmark, France, Germany, Greece, Ireland, Italy, Netherlands, Portugal, Spain, Switzerland and the United Kingdom) and 559 patients were enrolled in Greece. RESULTS: Compared to their counterparts in western Europe and the entire cohort, Greeks were younger (p<0.0001, p<0.0001, respectively), more predominantly male (p<0.0039, p<0.0001), with a higher body mass index (p<0.0002, p<0.0001) and a larger waist circumference (p<0.0001, p<0.0001), as well as a higher prevalence of family history of CAD (p<0.0008, 0.0005), hyperlipidemia (p<0.0001, p<0.0001) and smoking (p<0.0001, p<0.0001). Noninvasive testing (p<0.0001, p<0.0001, respectively) and coronary angiography (p<0.0001, 0.0013) along with surgical revascularization (CABG) (p<0.0001, 0.0088) were performed more often in Greece. Antiplatelets, b-blockers and lipid lowering medications were used to an equal extent in Greece as in the other two cohorts. CONCLUSION: There are substantial differences in demographics, clinical profiles and treatment in patients with stable CAD within the data set, which are also observed for Greek data. Interestingly, these differences are consistent in relation to the global as well as the western European data.

Transcatheter aortic valve implantation: restoring the qualities of life in old age.

Transcatheter aortic valve implantation (TAVI) is a tremendous therapeutic advance for patients with severe aortic stenosis and high-surgical risk. Since TAVI-treated patients are elderly with multiple co-existing conditions, limited life expectancy and disproportionate health-care expenditures, the aspect of the health-related quality of life (HRQoL) benefits becomes of fundamental importance. Based on recent evidence, TAVI appears to improve significantly HRQoL measures compared with optimal standard care, which are restored to age-adjusted population norms over time.
