chest pain with aortic insufficiency is what?

28 y/o female with lupus presents with pleuritic knife like chest pain, low grade fever, sitting up and leaning fwd in stretcher - what is most likely dx?

pericarditis

college kid presents with severe chest pain - hx significant for heavy drinking night prior

boerhaave's syndrome

smoker with chest pain and widened complex tachycardia - what should you do next?

cardiovert

what is the most common reason as to why pts get Dressler's syndrome?

Heparin treatment

What is the worry that you have as PA when a pt gets Dressler's syndrome?

that they will get pericardial effusion and cardiac tamponade

What are the signs of pericarditis on the EKG?

depressed PR; diffuse ST elevations

all diastolic murmurs are pathologic - T or F

TRUE!!!!

pt comes into the ER with MI, receives tx. later, the same pt has a drop in BP and increase in pulse. extremities are cool; pansystolic murmur present - III/VI @ apex, radiating to left shoulder with S3 gallop. Dx? and why?

mitral regurgitation due to papillary muscle rupture

pt comes into the ER with MI, receives tx. later, the same pt has a drop in BP and increase in pulse. extremities are cool; pansystolic murmur present - V/VI (thrill present) at left lower sternal border; moist rales bilaterally. Dx?

ventricular septal defect

what are your 3 pansystolic murmurs?

mitral regurg, tricuspid regurg, and ventricular septal defect

what is this: An increase in central venous pressure with inspiration ?

Kussmaul's sign. Normally, there is a decrease in jugular venous pressure with inspiration. Kussmaul's sign can be seen with restrictive cardiomyopathy. The heart is normal sized with restrictive cardiomyopathy.

Physical findings of _____ include: Murmur heard best at apex and left sternal border Systolic ejection murmur Pulsus bisferiens Signs increased by Valsalva maneuver

hypertrophic subaortic stenosis

congenital heart defect in which the septal leaflet of the tricuspid valve is displaced towards the apex of the right ventricle of the heart.

ebstein anomaly

the most common cause of death in a young athlete

Hypertrophic Obstructive Cardiomyopathy (HOCM)

seen with tricuspid regurgitation. The sign is positive if there is an increase in the intensity of the murmur with inspiration

Carvallo's sign

is usually congenital and frequently asymptomatic. The intensity of the click decreases with inspiration.

pulmonary stenosis

It produces a 'continuous machinery murmur' with late systolic accentuation, maximally heard at the second rib near the sternum.

pda

s more common in males and associated with other abnormalities, most common of which is bicuspid aortic valve. It may be asymptomatic for years and is often detected in routine x-ray. The signs will include wide splitting of the second heart sound and a systolic flow murmur over the pulmonary valve.

Coarctation of the aorta

what do you expect to find on the chest xray of a pt with coarctation of the aorta? (2)

Left ventricular hypertrophy (LVH) and a notch in the aorta

A prominent aorta, pulmonary artery, and left atrium on xray represents what?

patent ductus arteriosus

Right ventricular hypertrophy (RVH) and large pulmonary arteries on xray represents what?

atrial septal defect

what is the immediate diagnostic imaging modality of choice for patients with suspected aortic dissection?

CT scan

dilated IVC, RA collapse, and then RV collapse all point to what?

cardiac tamponade

a decrease in systolic contraction of an ischemic area (segment) of the myocardium is called what?

regional wall motion abnormality

i say pulsus tardus, you say ?

if your cardiac apical impulse is lateral and downwardly displaced, what is wrong with the LV?

dilated

if you have a double systolic apical impulse, what is going on with your heart?

hypertrophic cardiomyopathy

what is going on with your heart if you have a sustained "lift" at the lower left sternal border?

RVH

why does the left ventricle hypertrophy with MR?

f a lot of blood leaks into the left atrium when the left ventricle contracts, less blood is pumped into the body via the aorta. The heart compensates for this. The wall of the left ventricle may become thicker, the ventricle may enlarge, and the heart rate may increase.

what is the worry with young patients who have MR? CHRONIC MR

they will develop AFIB which leads to an MI

which sound is more indicative of heart failure? s3 or s4?

s3!!!
