“…Although many patients are asymptomatic with preserved LV systolic function, others develop heart failure, thromboembolic events, and malignant arrhythmias. Heart failure symptoms varying from mild to severe have been observed in approximately half of patients (7). Systolic dysfunction and arrhythmias may be a consequence of dysfunction at the microcirculation level and subepicardial hypoperfusion (4).…”

Left Ventricular Noncompaction with Bicuspid Aortic Valve: A Case Report with a Comprehensive Cardiac MRI Approach

et al. 2019

Noncompaction of ventricular myocardium, once thought to represent a rare cardiomyopathy, is being diagnosed with increased frequency. It is often accompanied by various congenital heart diseases. Coexisting valvular anomalies are an emerging issue that requires further investigation in patients with noncompaction cardiomyopathy, because they can increase the potential for adverse clinical events. This article describes the case of a 45-year-old male diagnosed with left ventricular noncompaction (LVNC) with a bicuspid aortic valve. Progressive deterioration of cardiac function in this patient could be explained by myocardial fibrosis and accompanying valvular anomalies on cardiac magnetic resonance imaging (MRI). The clinical implications of cardiac MRI in noncompaction cardiomyopathy are discussed based on its ability to depict both morphological and functional features. Considering the potential for coexisting congenital heart disease to declines in cardiac function, patients with LVNC should be comprehensively evaluated for concurrent cardiac anomalies and myocardial fibrosis.

“…Furthermore, in patients with myocarditis, EMB provides not only diagnostic clues but also therapeutic and prognostic implications (16, 17). Despite all advantages of EMB-based diagnosis, EMB procedure itself is perceived to carry a high risk of major adverse events, such as cardiac tamponade and some raise a question about the role of EMB in the era of new cardiac imaging modalities such as cardiac magnetic resonance imaging (18, 19). However, histological confirmation is still needed in many patients in whom non-invasive evaluation is inconclusive.…”

Complication Rate of Transfemoral Endomyocardial Biopsy with Fluoroscopic and Two-dimensional Echocardiographic Guidance: A 10-Year Experience of 228 Consecutive Procedures

Endomyocardial biopsy (EMB) is one of the reliable methods for the diagnosis of various cardiac diseases. However, EMB can cause various complications. The purpose of this study is to evaluate the complication of transfemoral EMB with both fluoroscopic and two-dimensional (2-D) echocardiographic guidance. A total of 228 patients (148 men; 46.0±14.6 yr-old) who underwent EMB at Kyungpook National University Hospital from January 2002 to June 2012 were included. EMB was performed via the right femoral approach with the guidance of both echocardiography and fluoroscopy. Overall, EMB-related complications occurred in 21 patients (9.2%) including one case (0.4%) with cardiac tamponade requiring emergent pericardiocentesis, four cases (1.8%) with small pericardial effusion without pericardiocentesis, two cases (0.9%) with hemodynamically unstable ventricular tachycardia (VT), one case (0.4%) with nonsustained VT, one case (0.4%) with tricuspid regurgitation, twelve cases (5.3%) with right bundle branch block. There was no occurrence of either EMB-related death or cardiac surgery. Left ventricular ejection fraction was significantly lower (32.0±18.7% vs 42.0±19.1%, P=0.023) and left ventricular end-diastolic dimension was larger (60.0±10.0 mm vs 54.2±10.2 mm, P=0.013) in patients with EMB related complications than in those without. It is concluded that transfemoral EMB with fluoroscopic and 2-D echocardiographic guidance is a safe procedure with low complication rate.

“…In dilated cardiomyopathy, the LV is dilated and there is global systolic dysfunction. A nonischemic pattern of LGE may be seen, in a mid-myocardial or subepicardial distribution depending on the underlying aetiology [36]. A linear mid-myocardial pattern has been described in idiopathic dilated cardiomyopathy [36].…”

Left ventricular (LV) thickening can be due to hypertrophy (concentric, asymmetric, eccentric) or remodelling (concentric or asymmetric). Pathological thickening may be caused by pressure overload, volume overload, infiltrative disorders, hypertrophic cardiomyopathy, athlete’s heart or neoplastic infiltration. Magnetic resonance imaging (MRI) plays an important role in the comprehensive evaluation of LV thickening, including: establishing diagnosis, determining LV geometry, establishing aetiology, quantification, identifying prognostic factors, serial follow-up and treatment response. In this article, we review the aetiologies and pathophysiology of LV thickening, and demonstrate the comprehensive role of MRI in the evaluation of LV thickening.Teaching Points• MRI plays an important role in the evaluation of LV thickening.• LV thickening can be due to either hypertrophy or remodelling.• Pathological thickening can be due to pressure/volume overload or infiltrative disorders.Electronic supplementary materialThe online version of this article (doi:10.1007/s13244-017-0549-2) contains supplementary material, which is available to authorized users.
