An unruptured sinus of Valsalva aneurysm is rare and is usually asymptomatic until a symptom associated with its complication develops. Hence, an unruptured sinus of Valsalva aneurysm is not infrequently missed unless echocardiogram is performed with other indications. An unruptured sinus of Valsalva aneurysm rarely protrudes into the right ventricular outflow tract, causing the right ventricular outflow tract obstruction. In this report, I describe a rare case of unruptured sinus of Valsalva aneurysm producing the right ventricular outflow tract obstruction, which was incidentally detected by echocardiography.

Many cases have been reported hemolytic anemia and left ventricular outflow obstruction with systolic anterior motion developing after bioprosthetic valve replacement. We report a case of hemolytic anemia and left ventricular outflow tract obstruction occured after mitral valve repair using Duran ring and were resolved by preservative therapy.

In small children with left ventricular outflow tract obstruction, a few methods of surgical treatment could be considrred. The pulmonary autogrart provides a promising options for aortic valve replacement as part of the aortoventriculoplasty procedure in children. We report a successfully treated congenital aortic stcnoinsufricicncy with severe left ventricular dysfunction in an early infant with the aortoventriculoplasty using thc pulmonary autograft (the Ross-Konno procedure).

A 66-year-old man presented with exertional dyspnea. He was found to have an unruptured aneurysm of the right sinus of Valsalva causing significant right ventricular outflow obstruction. This aneurysm was diagnosed by transthoracic two-dimensional echocardiography, transthoracic three-dimensional echocardiography, transesophageal echocardiography, contrast echocardiography and 64-slice multidetector cardiac computed tomography. Because unruptured aneurysms of the sinus of Valsalva are rarely symptomatic, they can be difficult to detect. However, the unruptured aneurysm of the right sinus of Valsalva in this case caused significant right ventricular outflow tract obstruction, resulting in exertional dyspnea.

Cardiac myxoma is the most common primary cardiac tumor, but ventricular myxoma accounts for only 5% of the cases. We report a case of a 62-year-old woman with a left ventricular myxoma emerging from the ventricular side of the mitral valve that led to left ventricular outflow tract obstruction. The patient complained of chest discomfort and dyspnea. A mobile intracardiac mass was seen on echocardiography. The mass was excised and confirmed to be a myxoma by histopathological examination. She was discharged from the hospital without complications and remains asymptomatic.

The pathophysiology, clinical presentation and prognosis of left ventricular obstruction present an important cardiological problem. Various anatomical and functional abnormality can cause this phenomenon. Rarely, left ventricular outflow obstruction can result after mitral valve surgery. We experienced a case of left ventricular outflow obdtruction 13 years after mitral valve replavement. The diagnosis was made using two-dimensinal Doppler echocardiography and confirmed by cardiac catheterization. The pressure gradient across the left ventricular outflow obstruction was 96mmHg. A second mitral valve replacement was performed. Because severe fibrosis, pannis around the prosthetic mitral valve and a subaortic web were detected during the operation, the subaortic web was removes.

Supravalvular aortic stenosis is a rare cause of left ventricular outflow obstruction in adults. It occurs as an isolated defect sporadically or as a hereditary basis with an autosomal dominant trait without further phenotypical anomalies, or as a part of the Williams syndrome with mental retardation and multiple anomalies. In this report, we present a case of williams syndome associated with megacoronary artery.

Most cases of cardiac metastasis from renal cell carcinoma (RCC) involve the vena cava or right atrium. Left ventricular metastases from RCC without involving the vena cava or right atrium are extremely rare. Herein we report a case of RCC with left ventricular metastasis causing left ventricular outflow obstruction (LVOT).

Sinus of Valsalva aneurysm (SVA) is an uncommon anomaly of the aorta. Rupture of SVA often precipitates dramatic clinical complications, including heart failures. Right SVAs are the most common type, and when they rupture, they usually rupture into the right ventricle or right atrium. Rupture into left ventricle or interventricular septum is rare. Herein, we report a case of right SVA rupture with dissection into interventricular septum, which produced significant left ventricular outflow tract obstruction and aortic regurgitation. The case was successfully treated by surgical operation.
