The Unusual Suspect: Anemia-induced Systolic Anterior Motion of the Mitral Valve and Intraventricular Dynamic Obstruction in a Hyperdynamic Heart as Unexpected Causes of Exertional Dyspnea after Cardiac Surgery
نویسندگان
چکیده
Dynamic left ventricular (LV) outflow tract obstruction is a characteristic feature of hypertrophic cardiomyopathy; however, it can also occur in association with hyperdynamic LV contraction and/or changes in the cardiac loading condition, even in a structurally normal or near-normal heart. Here, we report a case of anemia-induced systolic anterior motion of the mitral valve and the resultant intraventricular obstruction in a patient who underwent coronary artery bypass grafting and suffered from anemia associated with recurrent gastrointestinal bleeding.

Dynamic obstruction to left ventricular (LV) outflow as a result of mitral valve systolic anterior motion is a potentially deleterious facet of hypertrophic cardiomyopathy (HCM).1–4 In many patients, outflow obstruction is largely responsible for disabling symptoms of heart failure such as exertional dyspnea (often with chest pain), fatigue, and orthopnea.1,3 Consequently, treatment interventio...

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. We report three cases of ALCAPA who survived to adulthood. The first case was a 51-year-old woman who complained of typical chest pain that was diagnosed with ALCAPA using cardiac catheterization and coronary computed tomographic angiography (CTA). The second case was a 30-...

Occurrence of dynamic left ventricular outflow tract (LVOT) obstruction is not infrequent in critically ill patients, and it is associated with potential danger. Here, we report a case of transient heart failure with hemodynamic deterioration paradoxically induced by extreme dehydration. This article describes clinical features of the patient and echocardiographic findings of dynamic LVOT obstr...
متن کاملHigh-risk Coronary Artery Bypass Grafting and Mitral Valve Replacement in a HIV Positive Patient
Certain subsets of high-risk mitral valve patients are not suitable candidates for transcatheter therapies. The objective of this report is to present a young patient with combined mitral valve and coronary artery disease to illustrate these challenges.In this report, we present a 47-year-old man with longstanding HIV infection who was referred with severe mitral regurgitation (MR) and profound...
