It is almost universal at present for textbooks of anatomy to illustrate the heart as if removed from the body and positioned on its apex, the so‐called Valentine situation. In the years prior to the emergence of interventional techniques to treat cardiac diseases, this approach was of limited...
What is a mirror-image dextrocardia? Mirror-image dextrocardia isthe most common form of cardiac malposition encounteredand is almost always associated with situs inversus of the abdominal organs. The anatomic right ventricle is anterior to the left ventricle and the aortic arch curves to the right...
The apex of the heart is lowest tip of the organ that points downward at the base, forming what almost looks like a rounded point. “Apex” is a Latin word meaning “summit” or “peak,” and this part of the heart can be thought of in those terms, too. It’s formed mostly by ...

The pericardium isa fibrous sac that encloses the heart and great vessels. It keeps the heart in a stable location in the mediastinum, facilitates its movements, and separates it from the lungs and other mediastinal structures. It also supports physiological cardiac function.[1][2][3] ...

Which parts of the aorta give off the visceral and parietal branches?
He had an exercise stress test and went very far on it, but his hr went above 200 and his bp was 240/60 when they stopped the test. He was lightheaded. That was the main reason we were there for the test. They did lots of cardiac tests and he has had a MRI and EEG - all ...
implant and sudden change despite apparent ApVs on the ECG, we did a simple manoeuvre of switching off one channel at a time, and recording the surface ECGs during device interrogation using patient care system (PCS) programmer (Merlin™, Abbott cardiac rhythm management, Plymouth, MN, USA)...
