Aortic Aneurysms: Defusing the Ticking Time Bomb

Aortic Aneurysms: Defusing the Ticking Time Bomb

We discussed aortic aneurysms in last week’s blog and this week we’ll talk about what we do to prevent their rupture.  First, we have to know that the aneurysm is there. Widespread screening for aneurysms is not practical, so it is usually the case that they are discovered by chance. For instance, a person may have nausea and abdominal pain and get…

Valvular Heart Disease: All the Rest

In the last two weeks, I have discussed the two most common valvular problems that we cardiologists see—AS and MR. This week I’ll give a quick overview of the other valvular problems that we can encounter. First of all, the aortic valve can also develop regurgitation. Called “AR,” aortic regurgitation, when severe, can lead to heart enlargement, shortness of breath, chest pain,…

Cardiomyopathy: When the Heart Muscle is Sick

A few weeks ago, I devoted a couple blogs to the subject of CHF (congestive heart failure). At the time, I discussed the differences between heart failure from systolic dysfunction (problems with the heart contracting/pumping) and that caused by diastolic dysfunction (problems during the relaxation phase of the cardiac cycle). These are clinical syndromes and are brought on by a variety of…
