Risk of delayed diagnosis in young patients with left ventricular non-compaction - a potential benefit of magnetic resonance imaging.

Background: Left ventricular non-compaction (LVNC) is a rare form of cardiomyopathy resulting from a disorder of endomyocardial morphogenesis associated with significantly increased risk of cardiovascular morbidity and premature mortality. Despite the widespread use of echocardiography, LVNC is commonly overlooked, often due to lack of knowledge about this disorder.

Methods And Results: A complex diagnostic process and follow-up was analysed in 24 patients diagnosed with LVNC between March 2002 and February 2016 (16 boys, 8 girls; age at presentation 9 days - 18 years; follow-up 2-7 years).

Myocardial scarring after repair of anomalous origin of the left coronary artery from pulmonary artery.

Objectives: Prognosis of patients with anomalous origin of the left coronary artery from pulmonary artery has dramatically improved as a result of both, early diagnosis and improvements in surgical techniques. Post surgical complications are rare and most patients show quick improvement of the left ventricular performance after repair with complete functional recovery within one year after surgery. Exercise-induced electrocardiographic changes have been found in patients postoperatively and scars and perfusion deficits of the left ventricle may not be detected by standard echocardiographic evaluation.
