A. Hypotension
B. Pulsus paradoxus
C. Muffled heart tones
D. Distended neck veins

A

Pulsus paradoxus

Beck triad is a collection of three clinical signs associated with pericardial tamponade which is due to an excessive accumulation of fluid within the pericardial sac. The three signs are: low blood pressure (weak pulse or narrow pulse pressure), muffled heart sounds, and raised jugular venous pressure.

81
Q

Indication for elective repair of an abdominal aortic aneurysm, EXCEPT:

A. Asymptomatic patient with a 6cm infrarenal aortic aneurysm
B. Asymptomatic patient with a 4.4 cm AAA
C. 5.5cm asymptomatic AAA
D. Leaking AAA

A

Asymptomatic patient with a 4.4 cm AAA

According to the 2018 SVS guidelines, if the AAA is between 4.0 and 4.9 cm, surveillance imaging at 12-month intervals is suggested. If the AAA is between 5.0 and 5.4 cm, surveillance imaging at 6-month intervals is suggested. If there is any evidence of rapid growth (>1 cm in 1 year), the AAA should be repaired. Patients with AAAs 5-6 cm in diameter may benefit from repair, especially if they have other contributing factors for rupture.

A. Blue toe syndrome
B. Stroke
C. Acute mesenteric ischemia
D. Popliteal entrapment syndrome

A

Popliteal entrapment syndrome

86
Q

The following are TRUE regarding Patent Ductus Arteriosus, EXCEPT:

A. Presentation depends on the degree of left-to-right shunt (pulmonary overcirculation and steal from systemic perfusion)
B. Indomethacin is given to induce medical closure
C. PDA is more common in Term than in Preterm infants
D. Communication between upper descending aorta and left main pulmonary

A

C. PDA is more common in Term than in Preterm infants

PDA increases dramatically with INCREASING PREMATURITY*

▪ Choice A: The ductus arteriosus is derived from the sixth aortic arch and normally extends from the main or left pulmonary artery to the upper descending thoracic aorta, distal to the left subclavian artery.

▪ Choice B: PDA results in a left-to-right shunt that depends on both the size of the ductal lumen and its total length. In isolated patent ductus arteriosus (PDA), signs and symptoms are consistent with left-to-right shunting. The shunt volume is determined by the size of the open communication and the pulmonary vascular resistance (PVR). (Source: Medscape)

▪ Choice D: In premature infants, aggressive intervention with indomethacin or ibuprofen to achieve early closure of the PDA.

87
Q

The following are Ductal- dependent lesions, EXCEPT:

A. Tricuspid atresia
B. Truncus Arteriosus
C. TOF
D. Ebstein’s anomaly

A

B. Truncus Arteriosus

TOF, Ebstein’s anomaly, and tricuspid atresia are ductal-dependent lesions.

Truncus arteriosus is a ductal-independent mixing lesion.

88
Q

This is commonly performed in carotid stenosis, right coronary artery stenosis.

A

Endarterectomy

89
Q

Relatively the same as embolectomy but wala mo ya gina kuha ang embolus. You insert a catheter into the blood vessel. Part of the area of the balloon where your area of stenosis is, and then inflate that balloon to stretch the plaque or buk-on mo sya. Usually it requires mga 15-60 mmHg of pressure to crack open that very hard stenotic area without damaging the intima. Once the plaque has cracked, mahumok na na sya and can increase the caliber of the lumen already. But if the plaque is too hard, the balloon may not be enough to open up the blood vessel so in order for that blood vessel to remain patent, you insert an expandable stent that is usually made of metal. It’s like a mesh, cylindrical section. It will push to keep that vessel patent, so that is stenting.

A

Balloon angioplasty with or without wall stent

90
Q

if you remove the plaque during this procedure, slice first the intima to get the clot and when you excise it there would be incomplete layer of your intima (not intact) ky ginkuha mo na imo plaque. That exposes already your endothelium and that can lead to clot formation also like in the virchows triad.

A

Endarterectomy

91
Q

surgical procedure wherein a catheter is inserted into the artery that contains a blood clot and at the tip of the catheter is a balloon that you can inflate and you remove the blood clot.

A. AV Bundle of His
B. Atrioventricular node
C. Right Bundle Branch
D. Left Bundle Branch

A

B. Atrioventricular node

▪ Base – Coronary Sinus, Thebesian Veins (located mostly at Right atrium)
▪ Lateral – Tendon of Todaro (tendinous structure connecting the valve of the inferior vena cava ostium to
the central fibrous body) and anteroseptal leaflet commissure/ septal annulus of the tricuspid valve.
▪ Apex- the AV node

108
Q

In the fetal circulation, blood from the inferior vena cava that enters the right atrium preferentially flows into:

A. The right ventricle through the tricuspid valve
B. The descending aorta via the ductus Arteriosus
C. The left atrium through the Foramen ovale
D. Lungs through the pulmonary artery

A

C. The left atrium through the Foramen ovale

Oxygen-rich blood from the placenta passes through the umbilical vein directly to the fetal liver, where
the circulation splits and flows into both the ductus venosus (20%–30% of flow) and portal sinus circulation. It then
passes into the inferior vena cava and enters the right atrium. The majority of this blood flows through the foramen
ovale, into the left atrium, then the left ventricle, and empties into the aorta (a small portion travels through the
pulmonary arteries to perfuse lung tissue)

109
Q

A. Atrial Septal Defect
B. Patent Ductus Arteriosus
C. Coarctation of the Aorta
