Iatrogenic aortic dissection is an infrequent complication of cardiac catheterization (0.03-0.06%) associated with up to 19% of mortality at 30 days. It was reported to mostly occur when using a 6-Fr guiding catheter to cannulate the right coronary artery. This life-threatening complication usually requires early surgical management and close imaging monitoring and control of systolic blood pressure. This case report describes a patient with iatrogenic aortic dissection during cardiac catheterization in symptomatic coronary artery disease...

Nikolaos Baritakis, Nikolaos Grapsas, Andreas Kotsalos, Periklis Davlouros
We present a rare case of a double-chambered right ventricle masquerading as a double-chambered left ventricle, which was found incidentally on cardiac imaging in an adult female patient with atypical chest pain. The most common form of double-chambered right ventricle is characterized by compartmentalization of the right ventricle by muscular bands into 2 distinct chambers. The main features of this malformation are a pressure gradient between the 2 compartments, and the frequent (up to 90%) association with a membranous ventricular septal defect...

RATIONALE: Although myocardial bridging (MB) is usually considered as benign, initial medical therapy and following surgical treatment in drug-refractory cases has been widely accepted for managing symptomatic MB. Before the patient proceeds to percutaneous or surgical intervention, however, the presence of objective ischemia in the corresponding myocardial territory should be documented. PATIENT CONCERN AND INTERVENTION: We herein report a 43-year-old male complaining of chest pain in whom cardiac CT with myocardial perfusion (cCTP) showed an MB of left anterior descending artery (LAD) with preoperative perfusion defect in corresponding myocardium and normalization of perfusion after supra-arterial myotomy...

Smartphones and tablets are widely used in medical fields, which can improve healthcare and reduce healthcare costs. Many medical applications for smartphones and tablets have already been developed and widely used by both health professionals and patients. Specifically, video recordings of fingertips made using a smartphone camera contain a pulsatile component caused by the cardiac pulse equivalent to that present in a photoplethysmographic signal. By performing peak detection on the pulsatile signal, it is possible to estimate a continuous heart rate and a respiratory rate...

Coronary artery ectasia (CAE), a variant of coronary artery anomalies, is a rare clinical entity. Although atherosclerotic coronary artery disease (CAD) is the most common cause of acute coronary syndrome (ACS), CAE also conveys a relatively high risk for potentially life-threatening cardiac events. We report a case of a 35-year-old male with two-vessel CAE, who presented with acute inferior wall ST election myocardial infarction (STEMI). After initiating medical therapy including bivalirudin, emergent percutaneous coronary intervention (PCI) with stenting of postero-lateral branch of right coronary artery (RCA) was performed...

Coronary artery fistulas (CAFs) are found in 0.3-0.8% of patients who undergo coronary angiography. CAFs are defined as single or multiple, small or large direct communications that arise from one or more coronary arteries and enter into one of the four cardiac chambers or major vessels. We present two cases of multiple coronary artery fistulas arising from diagonal and left anterior descending (LAD) branches of left coronary artery draining into the left ventricle. In both the cases, No intervention was performed...

Fabry disease (FD) is an X-linked lysosomal storage disorder caused by deficiency of α-galactosidase A enzyme. Cardiovascular (CV) disease is a common cause of mortality in FD, in particular as a result of heart failure and arrhythmia, with a significant proportion of events categorized as sudden. There are no clear models for risk prediction in FD. This systematic review aims to identify the risk factors for ventricular arrhythmia (VA) and sudden cardiac deaths (SCD) in FD. A systematic search was performed following PRISMA guidelines of EMBASE, Medline, PubMed, Web of Science, and Cochrane from inception to August 2016, focusing on identification of risk factors for the development of VA or SCD...

Two-dimensional (2D) speckle tracking echocardiography represents a novel, simple and reproducible technique for the estimation of left ventricular myocardial deformation (strain) and the evaluation of left ventricular twist mechanics. During the last few years, its clinical and prognostic implications in cardiomyopathies and hypertrophic cardiomyopathy (HCM) in particular have been rapidly increasing. Reduced global longitudinal strain is associated with more severe disease and confers an increased risk for major cardiac events, independently of other clinical and echocardiographic risk factors...

Diabetic cardiomyopathy is characterized by metabolic changes in the myocardium that promote a slow and silent dysfunction of muscle fibers, leading to myocardium remodelling and heart failure, independently of the presence of coronary artery diseases or hypertension. At present, no imaging methods allow an early diagnosis of this disease. Circulating miRNAs in plasma have been proposed as biomarkers in the prognosis of several cardiac diseases. This study aimed to determine whether circulating miRNAs could be potential biomarkers of diabetic cardiomyopathy...
