Isolated Ventricular Noncompaction Cardiomyopathy Presenting as Recurrent Syncope

Isolated ventricular noncompaction (IVNC) occurs because of interruption of trabecular morphogenesis in the myocardium leading to ventricular noncompaction. Patients present with heart failure or with systemic complications secondary to thromboembolism or arrhythmias. High index of suspicion is necessary for early diagnosis. We present a case of 48-year-old male with unexplained recurrent syncope who was eventually diagnosed with IVNC

Severe Mitral Stenosis With Atypical Presentation: Hemorrhagic Pleural Effusion--a Case Report and Literature Review.

Mitral stenosis is a well-described valvular heart disease. We report a 68-year-old patient with an unusual presentation of mitral stenosis. He presented with recurrent episodes of hemorrhagic pleural effusion. Afterwards, an extensive atrial thrombosis complicated his course of illness. We will discuss how the clinical presentation of mitral stenosis is mainly dictated by the underlying pathophysiology of the disease. Also, the need for anticoagulation in the setting of mitral stenosis is often linked to the presence of atrial fibrillation. We will discuss the independent risk factors for thromboembolism in the setting of mitral stenosis. Finally, a review of the current recommendation for anticoagulation is conferred

Mortality and Major Adverse Cardiovascular Events After Transcatheter Aortic Valve Replacement Using Edwards Valve Versus Corevalve: A Meta-Analysis

Objectives: In patients with severe aortic stenosis who are at high risk for surgery, transcatheter aortic valve replacement (TAVR) has emerged as an alternative procedure using EV or CV. The objective of this meta-analysis is to compare 1-year mortality and major adverse cardiovascular and cerebrovascular events (MACCE) between Edwards valve (EV) and Medtronic CoreValve (CV). Methods: PubMed and the Cochrane Center Register of Controlled Trials were searched through December 2014. Twenty seven studies (n = 12,249) comparing TAVR procedure that used EV (n = 5745) and CV (n = 6504) were included. End points were procedural success rates, post-procedural mortality, myocardial infarction (MI), stroke, major bleeding, major vascular complications, incidence of new permanent pacemaker (PPM) placement and new left bundle branch block (LBBB). The odds ratio (OR) with 95% confidence interval (CI) was computed and p \u3c 0.05 was considered for significance. Results: There were no significant differences between EV and CV for post-procedural in-hospital, 30-day and 1-year all-cause mortality rates (p = 0.53, 0.33 and 0.94 respectively), cardiovascular mortality (p = 0.61), stroke (p = 0.54), major bleeding (p = 0.25) and major vascular complications (p = 0.27). MI was significantly lower with EV compared to CV (OR: 0.56, CI: 0.35-0.89, p = 0.01). Placement of new PPM and new onset LBBB were significantly higher in CV compared to EV (OR: 3.35, CI: 2.96-3.79, p \u3c 0.00001 and OR: 6.55, CI: 4.76-9.03, p \u3c 0.00001 respectively). Conclusions: The results of our meta-analysis suggest that TAVR procedure using CV may be associated with a higher incidence of MI, new PPM placement, and new onset LBBB compared to EV. However, the type of valve placed does not affect mortality

Comparison of on-Treatment Platelet Reactivity Between Triple Antiplatelet Therapy With Cilostazol and Standard Dual Antiplatelet Therapy in Patients Undergoing Coronary Interventions: A Meta-Analysis

Background: The recent literature has shown that triple antiplatelet therapy with cilostazol in addition to the standard dual antiplatelet therapy with aspirin and clopidogrel may reduce platelet reactivity and improve clinical outcomes following percutaneous coronary intervention. The purpose of this meta-analysis is to compare the efficacy of triple antiplatelet therapy and dual antiplatelet therapy in regard to on-treatment platelet reactivity. Methods: Nine studies (n = 2179) comparing on-treatment platelet reactivity between dual antiplatelet therapy (n = 1193) and triple antiplatelet therapy (n = 986) in patients undergoing percutaneous coronary intervention were included. Primary end points were P2Y12 reaction unit (PRU) and platelet reactivity index (PRI). Secondary end points were platelet aggregation with adenosine diphosphate (ADP) 5 and 20 μmol/L and P2Y12% inhibition. Mean difference (MD) and 95% confidence intervals (CI) were computed and 2-sided α error \u3c.05 was considered as a level of significance. Results: Compared to dual antiplatelet therapy, triple antiplatelet therapy had significantly lower maximum platelet aggregation with ADP 5 μmol/L (MD: -14.4, CI: -21.6 to -7.2, P \u3c .001) and 20 mmol/L (MD: -14.9, CI: -22.9 to -6.8, P \u3c .001), significantly lower PRUs (MD: -45, CI: -59.4 to -30.6, P \u3c .001) and PRI (MD: -26, CI: -36.8 to -15.2, P \u3c .001), and significantly higher P2Y12% inhibition (MD: 18.5, CI: 2.3 to 34.6, P = .025). Conclusion: Addition of cilostazol to conventional dual antiplatelet therapy significantly lowers platelet reactivity and may explain a decrease in thromboembolic events following coronary intervention; however, additional studies evaluating clinical outcomes will be helpful to determine the benefit of triple antiplatelet therapy

Case of Acute ST Segment Elevation Myocardial Infarction in Infective Endocarditis-Management with Intra Coronary Stenting

Embolic events from infective endocarditis can cause acute coronary syndrome. Mortality rate is high and optimal management might be different from those chosen in setting of classic atherosclerotic coronary artery disease. We present a case of 56-year-old male who had received 5 weeks of antibiotics for aortic valve endocarditis and developed acute ST segment elevation myocardial infarction in hospital settings. Interestingly, patient had recent left heart catheterization that was normal. This was recognized as embolic event from sterile vegetation. Patient was managed with balloon angioplasty and placement of intracoronary stent. Following re-vascularization, patient chest pain and electrocardiogram normalized and he improved in short term. However due to multiple comorbidities he had to be intubated and placed on dialysis
