Pre- and Post-transcatheter Aortic Valve Replacement (TAVR) Serum Mean Platelet Volume Levels and All-Cause Mortality.

Background: Among the most frequent complications following transcatheter aortic valve replacement (TAVR) is hemostasis imbalance that presents either as thromboembolic or bleeding. Deviations in platelet count (PC) and mean platelet volume (MPV) are markers of hemostasis imbalance.

Objectives: To determine the predictive value of pre- and post-procedural PC and MPV fL 1-year all-cause mortality in patients who underwent TAVR.

Acute Kidney Injury Following Transcatheter Aortic Valve Implantation: Association with Contrast Media Dosage and Contrast Media Based Risk Predication Models.

The effect of contrast media (CM), delivered prior to- and during transcatheter aortic valve implantation (TAVI), on kidney function, following the procedure, is debatable. Consequently, the performance of CM-based, acute kidney injury (AKI) risk prediction models is also questionable. We retrospectively studied 210 patients that underwent TAVI.

Immediate Post-Procedural and Discharge Assessment of Mitral Valve Function Following Transcatheter Edge-to-Edge Mitral Valve Repair: Correlation and Association with Outcomes.

The correlation between residual mitral regurgitation (rMR) grade or mitral valve pressure gradient (MVPG), at transcatheter edge-to-edge mitral valve repair (TEEMr) completion and at discharge, is unknown. Furthermore, there is disagreement regarding rMR grade or MVPG from which prognosis diverts. We retrospectively studied 82 patients that underwent TEEMr.

The Relationship Between Body Mass Index and In-Hospital Mortality in Patients Following Coronary Artery Bypass Grafting Surgery.

The association between Body Mass Index (BMI) and clinical outcomes following coronary artery bypass grafting (CABG) remains controversial. Our objective was to investigate the real-world relationship between BMI and in-hospital clinical course and mortality, in patients who underwent CABG. A sampled cohort of patients who underwent CABG between October 2015 and December 2016 was identified in the National Inpatient Sample (NIS) database.

The Relationship Between Body Mass Index and In-Hospital Mortality in the Contemporary Era of an Acute Myocardial Infarction Management.

Background: The association between body mass index (BMI) and clinical outcomes following an acute myocardial infarction (AMI) remains controversial. Our objective was to investigate the relationship between BMI and AMI presentation, in-hospital clinical course and mortality in the contemporary era of AMI management.

Methods: Patients, hospitalized for an AMI between October 2015 and December 2016, were identified in the National Inpatient Sample (NIS) database.

Comparing Trajectory of Surgical Aortic Valve Replacement in the Early vs. Late Transcatheter Aortic Valve Replacement Era.

Traditionally, the only effective treatment for aortic stenosis was surgical aortic valve replacement (SAVR). Transcatheter aortic valve replacement (TAVR) was approved in the United States in late 2011 and provided a critical alternative therapy. Our aims were to investigate the trends in the utilization of SAVR in the early vs.

Predictors of Mitral Regurgitation Severity Improvement in Patients With Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation.

Background: Mitral regurgitation (MR) is frequently associated with severe aortic stenosis (AS). Significant MR is associated with less favorable prognosis after transcatheter aortic valve implantation (TAVI), including higher early and late mortality rate. The severity of MR is improved in about half of patients undergoing TAVI.

Pre- and Post-Transcatheter Aortic Valve Replacement Serum Brain Natriuretic Peptide Levels and All-Cause Mortality.

Background: Risk stratification in patients post-transcatheter aortic valve replacement (TAVR) is limited to and is based on clinical judgment and surgical scoring systems. Serum natriuretic peptides are used for general risk stratification in patients with aortic stenosis, reflecting the increase in their afterload and thereby stressing the need for valve intervention. The objective of this study was to determine the predictive value of pre- and post-procedural serum brain natriuretic peptide (BNP) on 1-year all-cause mortality in patients who underwent TAVR.

Trends in Utilization and Safety of In-Hospital Coronary Artery Bypass Grafting During a Non-ST-Segment Elevation Myocardial Infarction.

Up to 10% of non-ST-segment elevation myocardial infarction (NSTEMI) patients require coronary artery bypass graft (CABG) surgery during their hospitalization. Contemporary, real-world, data regarding CABG utilization and safety in NSTEMI patients are lacking. Our objectives were to investigate the contemporary trends in utilization and outcomes of CABG in patients admitted for NSTEMI.

The association between carotid calcium on dental panoramic radiographs and coronary calcium score on chest computerized tomography.

Objectives: Coronary artery calcium measured by CT predicts future coronary events. Similarly, carotid artery calcium on dental panoramic radiographs has been associated with increased cardiovascular events. Pre-procedural assessment of candidates for valve replacement in our institution includes panoramic radiographs and chest tomography.

Dental screening prior to valve interventions: Should we prepare transcatheter aortic valve replacement candidates for "surgery"?

Background: 40% of cases of infective endocarditis (IE) are likely caused by oral bacteria. IE prevalence after transcatheter aortic valve replacement (TAVR) is comparable to IE following surgical prosthetic valve replacement (SVR). Current guidelines recommend pre-operative dental screening for SVR, without specific recommendations regarding TAVR.

Serum BNP levels are associated with malignant pericardial effusion.

Introduction: The development of malignant pericardial effusion indicates a poor prognosis and is the leading cause of cardiac tamponade. The objectives of the study were to examine the levels of BNP in traumatic, malignant and non-malignant pericardial effusion etiologies, and to assess the value of serum and pericardial fluid BNP levels in the prognosis of malignant pericardial effusion.

Methods: A of 56 patients with clinical and echocardiographic diagnosis of pre-tamponade or tamponade who required pericardiocentesis were included in the study.

Ethnicity of Symptomatic Coronary Artery Disease Referred for Coronary Angiography in the Galilee: Prevalence, Risk Factors, and a Case for Screening and Modification.

Background: Coronary artery disease (CAD) has known risk factors. Individual risks related to specific ethnicities are complex and depend on genetic predisposition and lifestyle.

Objectives: To compare the nature and prevalence of risk factors in Arab and non-Arab ethnic patients with symptomatic obstructive CAD referred for coronary angiography.

Left Circumflex Coronary Artery as the Culprit Vessel in ST-Segment-Elevation Myocardial Infarction.

The prevalence of the left circumflex coronary artery (LCx) as the culprit vessel in ST-segment-elevation myocardial infarction (STEMI) is reportedly lowest among that of the 3 main epicardial arteries, and has not been described for non-STEMI (NSTEMI) and stable angina pectoris. We sought to define the distribution of culprit arteries in these clinical presentations and suggest mechanisms for the differences. We reviewed 189 coronary angiograms of patients with STEMI, 203 with NSTEMI, and 548 with stable angina (n=940), and compared distributions of stenotic and culprit coronary arteries (lesions prompting intervention).

Takotsubo cardiomyopathy caused by epinephrine-treated bee sting anaphylaxis: a case report.

Introduction: Stress-induced cardiomyopathy (Takotsubo) after bee stings in patients who have received catecholamines is rare. Endogenous as well as exogenous administration of catecholamines is thought to trigger stress-induced cardiomyopathy.

Case Presentation: A 37-year-old healthy white woman was stung by an unknown Hymenoptera that resulted in an anaphylactic reaction.

Accuracy and long-term prognostic value of pacing stress echocardiography compared with dipyridamole tl201 emission computed tomography in patients with a permanent pacemaker and known or suspected coronary artery disease.

Objectives: Myocardial ischemia is difficult to assess by noninvasive methods in patients with a permanent pacemaker. Pacing stress echocardiography (PASE) has been used successfully in the detection of coronary artery disease (CAD). However, there are no data comparing PASE and other methods.
