We describe a case of a 45-year-old man presenting with acute myocardial infarction investigated by computed tomography coronary angiography. Interestingly all three coronary arteries arose from the right coronary cusp. The left anterior descending artery (LAD) subtended an acute angle from the aortic root, associated with significant kinking and stenosis at the ostium, before passing anteriorly, taking a sub-pulmonic course and descending in the anterior interventricular groove.

Isolated pulmonic valve endocarditis is an uncommon clinical entity and is usually associated with intravenous drug abuse. We describe a case of isolated pulmonary valve endocarditis in a young woman with no apparent precipitating factors other than a history of recent normal delivery. During the clinical course she suffered a pulmonary embolism which could be managed conservatively and she was discharged after a 4-week course of antibiotic therapy. Read More

A 46-year-old female diagnosed several years ago with arterial hypertension and an ischemic stroke with significant recovery was admitted for dyspnea on usual physical activity and fatigue. Physical examination revealed signs of heart failure with crackles on both lung bases, distented jugular veins, accentuated pulmonic valve closure (P2) and tricuspid regurgitation murmur. Echocardiography identified a large tumor in the left atrium, suggestive of atrial myxoma, which caused a severe functional mitral stenosis and produced severe pulmonary hypertension. Read More

Objectives: Postoperative dyspnea is common after cardiac surgery, even in low-risk patients. Cardiac surgeons and anesthesiologists are familiar with patients suffering from dyspnea in the early postoperative period, but in some cases, conventional treatment strategies may be ineffective, and a consultation with a pulmonologist may be required. The aim of this study is to investigate the causes of dyspnea after cardiac surgery in this particular patient group. Read More

Identification of coronary anomalies has been reported using multidetector-row computed tomographic (MDCT) angiography with electrocardiographic gating. However, the utility of non-electrocardiographic-gated 16-row computed tomographic for MDCT for the identification of coronary artery anatomy or anomalies to the authors' knowledge has not been fully investigated.

Pulmonary and/or tricuspid valve dysfunction is common among individuals with congenital heart disease, and surgical intervention often carries prohibitive risks. Transcatheter valve replacement (TVR) of the right-sided cardiac valves has become a viable treatment option over the past two decades, while continued technological development aims to broaden its applicability to an even larger portion of those with repaired congenital heart disease. To date, two transcatheter valves have been approved for use in patients with dysfunctional right ventricular to pulmonary artery conduits as well as those with failing pulmonic bioprosthetic valves, and are also used off-label in the "native" RVOT and within surgically repaired/replaced but failing tricuspid valves.

Aims: The assumption of equivalence between right ventricular and pulmonary arterial systolic pressure is fundamental to several assessments of right ventricular or pulmonary vascular hemodynamic function. Our aims were to 1) determine whether systolic pressure gradients develop across the right ventricular outflow tract in healthy adults during exercise, 2) examine the potential correlates of such gradients, and 3) consider the effect of such gradients on calculated indices of right ventricular function.
Methods And Results: Healthy untrained and endurance-trained adult volunteers were studied using right-heart catheterization at rest and during submaximal cycle ergometry. Read More

Background: Patients with congenital cardiovascular disease involving the right ventricular outflow tract and with prosthetic valves in the heart are at high risk for developing infective endocarditis (IE). Recently, there has been concern about relatively high rates of IE after percutaneous pulmonary valve implantation (PPVI). Although there are factors specific to percutaneous valves that could plausibly contribute to the risk of IE, including procedural steps prior to implantation such as crimping the valved stent or mechanical forces during dilation, little is known about actual risk factors for this complication.

Introduction: In cardiac magnetic resonance imaging (CMR), accurate flow measurements rely on perpendicular plane-alignment with flow direction. For 2D phase contrast (PC) cardiac magnetic resonance measurements, planes have to be defined during the examination of the heart, which is time consuming and error-prone. Collection of flow information of the entire volume of the heart by a 4D flow CMR postpones plane alignment to post-processing. Read More

Increased blood pressure in the pulmonary artery is referred to as pulmonary hypertension and often is linked to loud pulmonic valve closures. For the purpose of this paper, it was hypothesized that pulmonary circulation vibrations will create sounds similar to sounds created by vocal cords during speech and that subjects with pulmonary artery hypertension (PAH) could have unique sound signatures across four auscultatory sites. Using a digital stethoscope, heart sounds were recorded at the cardiac apex, 2 left intercostal space (2LICS), 2 right intercostal space (2RICS), and 4 left intercostal space (4LICS) undergoing simultaneous cardiac catheterization.

Background And Purpose: The diverse causes of right-sided heart failure (RHF) include, among others, primary cardiomyopathies with right ventricular (RV) involvement, RV ischemia and infarction, volume loading caused by cardiac lesions associated with congenital heart disease and valvular pathologies, and pressure loading resulting from pulmonic stenosis or pulmonary hypertension from a variety of causes, including left-sided heart disease. Progressive RV dysfunction in these disease states is associated with increased morbidity and mortality. The purpose of this scientific statement is to provide guidance on the assessment and management of RHF. Read More
