Tricuspid aortic valve will undergo calcification三尖瓣主动脉瓣钙化

An aortic valve need not be bicuspid to calcify. Sometimes in older adults, a normal tricuspid aortic valve will undergo calcification, a so-called “senile calcific aortic stenosis.” Nodules of calcification are seen on the cusps here.

A congenital bicuspid aortic valve 先天性的两瓣叶主动脉瓣

Here is a congenital bicuspid aortic valve. Most bicuspid valves are prone to calcification. Patients can remain relatively asymptomatic until the stenosis reaches a critical point when congestive heart failure rapidly ensues. The dense white nodules of calcification are present … 继续阅读

This is a quadricuspid valve 这是一个四尖瓣

This is an unusual anomaly (and not too significant for the patient).This demonstrates the power of simple observation and use of your knowledge of anatomy. Many conditions in medicine can be diagnosed by just describing what you see. How many … 继续阅读

Aortic stenosis 主动脉狭窄

The aorta is opened longitudinally here to reveal a coarctation. In the region of the narrowing, there was increased turbulence that led to increased atherosclerosis.

The aorta nattows 主动脉狭窄

This portion of aorta was resected from a patient with a coarctation. The aorta narrows postductally here to about a 3 mm opening.

A heart with both an atrial sepatl defect(ASD) and a muscular ventricular septal defect(VSD)一个心既是一种膈缺损(ASD)和一个肌肉发达的室间隔缺损(VSD)

Here is a heart with both an atrial septal defect (ASD) and a muscular ventricular septal defect (VSD). The heart is opened on the left side. Such small defects do not produce significant left-to-right shunting, but they do increase the … 继续阅读

VSD ventricular septal defect 室间隔缺损

This is the heart of a premature stillborn with Trisomy 13 in which a ventricular septal defect is visible in the membranous septum. About 90% of VSD’s are in the membranous septum and 10% in the muscular septum.

ASD(atrial septal defect)房间隔缺损

This large atrial septal defect with left-to-right shunt resulted in pulmonary hypertension with increased pulmonary arterial pressures that eventually led to reversal and right-to-left shunt, resulting in marked right ventricular hypertrophy. This result from a cardiac septal defect is known … 继续阅读

ASD (atrial septal defect)心房间隔缺损

In the region of the foramen ovale on the interatrial septum is a small atrial septal defect, as seen in this heart opened on the right side. Here the defect is not closed by the septum secundum, so a shunt … 继续阅读

A probe patent foramen ovale in an adult 一个探针卵圆孔未闭于成人

At the right is a probe patent foramen ovale in an adult. A metal probe lifts the septum secundum and reveals the opening. Normally, the left atrial pressure keeps the foramen closed, but if right atrial pressures rise with pulmonary … 继续阅读
