A Case Of Mislabeled Textbooks: Misnomer Of The Traditional "Bicaval" View., Laura Vaskelyte, Stefan Bertog, Ilona Hofmann, Bojan Jovanović, Markus Reinartz, Predrag Matić, Sameer Gafoor, Kolja Sievert, Horst Sievert

Articles, Abstracts, and Reports

Since the early beginning of the transesophageal echocardiography (TEE) era, standardized tomographic views describing cardiac key structures have been provided. They have become the basis of TEE and have not been modified for decades. During our recent structural interventional cases, it has come to our attention that the structure frequently labeled "inferior vena cava" in textbooks and journal articles illustrating the bicaval TEE view is, in fact, the coronary sinus. Our manuscript illustrates our observation.

Effect Of Comorbidity On Unplanned Readmissions After Percutaneous Coronary Intervention (From The Nationwide Readmission Database)., Chun Shing Kwok, Sara C Martinez, Samir Pancholy, Waqar Ahmed, Khaled Al-Shaibi, Jessica Potts, Mohamed Mohamed, Evangelos Kontopantelis, Nick Curzen, Mamas A Mamas

Articles, Abstracts, and Reports

It is unclear how comorbidity influences rates and causes of unplanned readmissions following percutaneous coronary intervention (PCI). We analyzed patients in the Nationwide Readmission Database who were admitted to hospital between 2010 and 2014. The comorbidity burden as defined by the Charlson Comorbidity Index (CCI). Primary outcomes were 30-day readmission rates and causes of readmission according to comorbidity burden. A total of 2,294,346 PCI procedures were included the analysis. The patients in CCI = 0, 1, 2 and ≥3 were 842,272(36.7%), 701,476(30.6%), 347,537(15.1%) and 403,061(17.6%), respectively. 219,227(9.6%) had an unplanned readmission within 30 days and rates by CCI group were …

Applying Genomics In Heart Transplantation., Brendan J Keating, Alexandre C Pereira, Michael Snyder, Brian D. Piening

Articles, Abstracts, and Reports

While advances in patient care and immunosuppressive pharmacotherapies have increased the lifespan of heart allograft recipients, there are still significant comorbidities post-transplantation and 5-year survival rates are still significant, at approximately 70%. The last decade has seen massive strides in genomics and other omics fields, including transcriptomics, with many of these advances now starting to impact heart transplant clinical care. This review summarizes a number of the key advances in genomics which are relevant for heart transplant outcomes, and we highlight the translational potential that such knowledge may bring to patient care within the next decade.

Tissue Specific Origin, Development, And Pathological Perspectives Of Pericytes., Tomoko Yamazaki, Yoh-Suke Mukouyama

Articles, Abstracts, and Reports

Pericytes are mural cells surrounding blood vessels, adjacent to endothelial cells. Pericytes play critical roles in maturation and maintenance of vascular branching morphogenesis. In the central nervous system (CNS), pericytes are necessary for the formation and regulation of the blood-brain barrier (BBB) and pericyte deficiency accompanies CNS diseases including multiple sclerosis, diabetic retinopathy, neonatal intraventricular hemorrhage, and neurodegenerative disorders. Despite the importance of pericytes, their developmental origins and phenotypic diversity remain incompletely understood. Pericytes express multiple markers and the origin of pericytes differs by tissue, which may cause difficulty for the identification and understanding of the ontogeny of pericytes. Also, …

Persistent Sex Disparities In Clinical Outcomes With Percutaneous Coronary Intervention: Insights From 6.6 Million Pci Procedures In The United States., Jessica Potts, Alex Sirker, Sara C Martinez, Martha Gulati, Mirvat Alasnag, Muhammad Rashid, Chun Shing Kwok, Joie Ensor, Danielle L Burke, Richard D Riley, Lene Holmvang, Mamas A Mamas

Articles, Abstracts, and Reports

BACKGROUND: Prior studies have reported inconsistencies in the baseline risk profile, comorbidity burden and their association with clinical outcomes in women compared to men. More importantly, there is limited data around the sex differences and how these have changed over time in contemporary percutaneous coronary intervention (PCI) practice.

METHODS AND RESULTS: We used the Nationwide Inpatient Sample to identify all PCI procedures based on ICD-9 procedure codes in the United States between 2004-2014 in adult patients. Descriptive statistics were used to describe sex-based differences in baseline characteristics and comorbidity burden of patients. Multivariable logistic regressions were used to investigate the …

Congenital Ventricular Diverticulum Or Aneurysm: A Difficult Diagnosis To Make., Lloyd Halpern, Carl Garabedian, Neil K Worrall

Articles, Abstracts, and Reports

A pouch protruding from the free wall of the left ventricle may be either a congenital ventricular diverticulum (CVD) or aneurysm (CVA). Being aware of these rare congenital anomalies is critical in making the diagnosis. Differentiating the two is important for treatment decisions. We describe a patient with dextrocardia, Tetralogy of Fallot, and a congenital left ventricular apical diverticulum diagnosed following the induction of anesthesia. CVD and CVA may present in the antenatal period through late adulthood with differing morphology, location, and symptoms. Echocardiography is paramount in the diagnosis and characterization of these lesions. If this anomaly is encountered after …
