Spontaneous coronary artery dissection (SCAD) is a variant of acute coronary syndrome (ACS) that is poorly understood. SCAD has been linked to fibromuscular dysplasia (FMD), connective tissue disease (CTD), pregnancy and hormonal imbalance, systemic inflammatory conditions (e.g. IBD, vasculitis), and coronary artery vasospasm rather than traditional cardiac risk factors. Symptomology generally accompanying SCAD is indistinguishable from ACS making the timely recognition and diagnosis vital for prompt treatment...

Coronary artery disease is a major cause of morbidity and mortality, and while most commonly is atherosclerotic, it can present with variable manifestations, both congenital and acquired. One such manifestation is coronary aneurysm, which is a localized dilatation of a coronary artery wall segment to greater than 1.5 times the adjacent normal segments. While a dilated outpouching of a coronary artery has been commonly classified as a coronary aneurysm, a non-dilated outpouching is rare and is referred to as a diverticulum, with only one previous case report in the literature...

Renal cell carcinoma (RCC) is an aggressive and lethal tumor that has a high frequency of metastatic spread to unpredictable sites. One quarter of patients have either distant metastases or significant local-regional disease with atypical symptoms on presentation. We present a 41-year-old patient with symptoms of right heart failure and was found to have metastatic renal cell carcinoma with enhancing tumor from left renal vein up to right atrium.

A case of a 77-year-old woman with a history of hypertrophic cardiomyopathy (HCM) presented with intermittent episodes of exertional dyspnea and chest discomfort. Her coronary angiogram revealed normal coronary arteries but with hypertrophic obstructive cardiomyopathy with an increasing left ventricular-aortic gradient on isoproterenol provocation. Likewise, an intensified gradient was observed after a premature ventricular contraction (PVC) that is distinguished as the Brockenbrough-Braunwald-Morrow sign substantiating confirmation of left ventricular outflow tract (LVOT) obstruction...

A case of a 73-year-old woman with a history of von Recklinghausen disease (neurofibromatosis type 1) who presented initially with a gradual onset of shortness of breath and lightheadedness with no associated fever, chills, angina, palpitations, cough, weight loss, night sweats, nausea, vomiting, or constipation. She was found to be severely bradycardic and in third degree atrioventricular block by her primary care physician. She was admitted in the hospital because of intermittent bouts of lightheadedness and progression of the shortness of breath...

We report a case of a 56-year-old man who presented initially with a sudden onset of right-sided facial droop and weakness, aphasia, and confusion with no associated fever, chills, syncope, fatigue, weight loss, night sweats, nausea, vomiting, diarrhea, odontalgia, palpitations, cough, or dyspnea. Code stroke was called and the patient received tissue plasminogen activator (tPA) with subsequent resolution of his symptoms. Cranial magnetic resonance imaging showed left frontal punctate cortical restricted diffusion consistent with subacute to acute infarction...

Background: We conducted a retrospective analysis to revisit the efficacy of four different commonly used antiarrhythmic drugs (AADs) in a single community hospital setting in the U.S. We used cardiac implantable electronic devices (CIEDs) to continuously monitor the patients for maintenance of sinus rhythm. The CIEDs in our study included insertable cardiac monitor (ICM), permanent pacemaker (PPM) and cardiac resynchronization therapy-defibrillator (CRT-D). The aim was to compare efficacy of commonly used AADs for maintenance of sinus rhythm in atrial fibrillation (AF) patients...

Background: Thrombosis is a complication of prosthetic valves on oral anticoagulants which is associated with significant morbidity and mortality. A re-operation carries a substantial risk, with mortality rate from 10% to 15% in selected series, which may be 2- or 3-folds higher in critically ill patients. This study conducted in a tertiary care cardiology unit aimed to evaluate the effectiveness and safety of thrombolytic therapy in stuck mitral bileaflet heart valves. Methods: As a prospective observational study, clinical symptoms and fluoroscopy were the mainstay in diagnosis of stuck mitral valve...

Background: The reactive oxygen metabolites (d-ROMs) test has recently been explored as a novel marker of oxidative stress in vivo and used in clinical settings. Conversely, data regarding the utility of the d-ROMs test as a predictor of patients with chronic heart failure (CHF) are limited. This prospective study aims to elucidate the efficacy of the d-ROMs test as a predictor of initial heart failure (HF) hospitalization in elderly patients with CHF. Methods: A total of 428 elderly outpatients with CHF with no history of HF hospitalization (108 males, 320 females; mean age, 75 ± 7 years) were enrolled...

Background: Red cell distribution width (RDW), a routine component of the complete blood count (CBC), measures variation in the size of circulating erythrocytes. It has been associated with several clinical outcomes in cardiovascular disease. We sought to strengthen the association between RDW and mortality in patients admitted for acute coronary syndrome (ACS) by pooling together data from available studies. Methods: Studies that fulfilled the following were identified for analysis: 1) observational; 2) included patients admitted for ACS; 3) reported data on all-cause or cardiovascular (CV) mortality in association with a low or high RDW; and 4) used logistic regression analysis to control for confounders...

Hua Ling, Ebony Andrews, David Ombengi, Fang Li
Background: Patients with peripheral arterial disease (PAD) undergoing percutaneous coronary intervention (PCI) are at elevated risk of ischemic and bleeding events. However, the optimal duration of dual antiplatelet therapy (DAPT) after PCI in patients with PAD remains unclear. Methods: A systematic literature search was performed through June 2017 using PubMed, EMBASE and Cochrane databases with the following key terms: "dual antiplatelet therapy", "P2Y12 inhibitor", "myocardial infarction", "percutaneous coronary intervention", "stent", "peripheral arterial disease", and "ankle-brachial index"...

Mitroflow aortic prosthesis dysfunction in case of complex vascular disease is considered a challenging scenario. Because of the high risk for surgical reoperation and the presence of chronic aortic dissection originated from a calcified Kommerel diverticulum, we considered to perform a transapical valve-in-valve transcatheter aortic valve implantation (TAVI) procedure. Myocardial ischemia is a dreadful complication reported in valve-in-valve TAVI procedures, mainly in patients with degenerated Mitroflow aortic bioprostheses...

The antiphospholipid antibody syndrome (APS) is defined by a state of hypercoagulability secondary to an autoimmune disorder. There are evidences that approximately 2.8-5.5% of cases of acute myocardial infarction (AMI) in young individuals are secondary to APS. In this case report, three coronary artery thromboses occurring within a short period are described. Initially, there was an ST-segment elevation (STEMI) in the presence of coronary artery disease (CAD), with the vessel being treated with stent implantation...

There has been an increase in number of cardiac implantable electronic devices (CIEDs) implantation and with this we have witnessed increased rates of CIED infection mainly in elderly population. It is important to assess conditions that may not reliably improve with cardiac pacing or those who lack adequate beneficial effect from permanent pacing before contemplating implantation or reimplantation of these devices. Sometimes, the initial cardiac pathology may revert obviating the need for reimplantation as in the two cases that we have discussed below...

Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Ectopic origin of right coronary artery (RCA) from opposite sinus is one of the most common and they are mainly benign, but at times may be malignant. We report a case of a 69-year-old male who underwent early invasive percutaneous coronary intervention for non-ST-segment elevation myocardial infarction (NSTEMI) where RCA arising from left sinus at the root of left main artery was culprit and various technical challenges were encountered while intervening in form of cannulation to tracking of hardwares...

Bartonella spp. are emerging pathogens that are reported as the cause of blood culture-negative endocarditis ( BCNE). However, echocardiographic features and assessment of this endocarditis remains unclear. Four patients with B. henselae endocarditis were identified. All patients had underlying cardiac conditions: rheumatic heart disease in three, congenital heart disease in one. Evidence of vegetations was found on the aortic valve in all patients with large, highly mobile vegetations and severely destroyed valves demonstrated by the transthoracic echocardiogram leading to severe aortic regurgitation and heart failure...

The communication from right to left through the interventricular septum of the heart became identified by the anatomical study for 4 years. One thousand nine hundred years ago, Galen stated that blood seeps through the perforations in the interventricular septum of the heart. However, William Harvey, working 400 years ago, failed to find any. The interventricular vessel is a slit between the fibers of the muscle feasible to be patent by relaxing and widening of the helical heart at the right atrial filling phase at the end of the diastole...

Background: Eptifibatide is a platelet glycoprotein IIb/IIIa receptor antagonist used for the prevention of cardiac ischemic complications of percutaneous coronary intervention (PCI). Eptifibatide has been used with bolus dose only or bolus plus infusion in patients undergoing PCI which have shown less complications, but the risk of bleeding has been increased. We aimed to compare the outcome and bleeding rate of bolus dose alone or plus infusion in elective PCI. Methods: In this quasi-experimental study, we compared the outcome of elective PCI following single bolus dose intracoronary (41 patients) or bolus plus intravenous infusion (19 patients) of eptifibatide...
