Paradoxical Heart Failure Precipitated by Profound Dehydration: Intraventricular Dynamic Obstruction and Significant Mitral Regurgitation in a Volume-Depleted Heart
نویسندگان
چکیده
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 obstruction and significant mitral regurgitation caused by systolic anterior motion of the mitral valve in a volume-depleted heart.

Evaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...
متن کاملSevere volume depletion leading to mitral insufficiency.
We report a patient with profound hypovolemia who developed dynamic left ventricular outflow tract obstruction and severe mitral regurgitation. Both the outflow tract obstruction and mitral regurgitation resolved with volume replacement. Unlike previous reports of dynamic left ventricular outflow obstruction and mitral regurgitation, the degree of mitral regurgitation was severe. Possible mecha...
متن کاملCoexistence of dynamic mitral regurgitation and dynamic left ventricular dyssynchrony in a patient with repeated episodes of acute pulmonary edema: improvement with cardiac resynchronization therapy.
A 69-year-old woman with idiopathic dilated cardiomyopathy and chronic heart failure experienced repeated hospital admissions for acute pulmonary edema with no recognizable precipitating factor. Worsening mitral regurgitation was triggered by exercise echocardiography and significant intraventricular dyssynchrony was elicited by low-dose dobutamine stress echocardiography. After cardiac resynch...

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...
متن کاملThe mechanism of decrease in dynamic mitral regurgitation during heart failure treatment: importance of reduction in the regurgitant orifice size.
OBJECTIVES The purpose of this study was to quantify and characterize the regurgitant flow pattern and regurgitant orifice area in patients undergoing therapy for severe heart failure using contemporary echocardiographic techniques. BACKGROUND Mitral regurgitation may be dynamic in patients with heart failure and ultimately correlate with outcome in a group of patients. METHODS Fourteen pat...
