Acute Respiratory Distress, Hypoxia, and a Large Right Ventricle on Bedside Ultrasound
A 50-something presented in acute hypoxic respiratory failure, alert and in respiratory distress. She required Bilevel positive pressure ventilation.Pulse was 139 and BP 99/75. She was diaphoretic.A bedside ultrasound was done immediately:Notice the very large RV and very small, but well functioning, left ventricle.What do you think?There were also B-lines (not shown).Here is here initial ECG:What do you think?There is sinus tach. There is a large S-wave in lead I. There is a Q-wave in III. Do these indicate acute right heart strain, typical of pulmonary embolism?No!First, there is no full S1Q...

Giant wide T inversion – Cardiology MCQ
Giant wide T inversion may be seen in all except:
a) After a cardiac arrest
b) Subarachnoid hemorrhage
c) Hyperkalemia
d) Takotsubo cardiomyopathy
Correct answer: c) Hyperkalemia
Giant T wave inversion can be broad and deep or just deep T inversions. A depth of T wave of 10 mm or above is generally considered as deep T inversion [1]. Giant T wave inversions with depth of 35 mm have also been described in literature [2]. Deep T inversions without gross increase in width can occur in ischemia and hypertrophic cardiomyopathy. In a study involving 864 patients with hypertrophic cardiomyopathy, 15% had giant T wave inversion ...

May-Thurner syndrome – Cardiology MCQ
May-Thurner syndrome is:
a) Chromosomal defect
b) Iliac vein compression by the crossing iliac artery
c) Coarctation of aorta with cerebral aneurysms
d) Pulmonary stenosis with webbing of the neck
Correct answer: b) Iliac vein compression by the crossing iliac artery
May-Thurner syndrome denotes iliac vein compression by the crossing iliac artery at the iliocaval junction. Usually it is the left iliac vein which is compressed by the right iliac artery. The compression increases the risk of deep vein thrombosis. Other names for the syndrome are iliac vein compression syndrome and Cockett syndrome. The obstruction may cause...

IVC filter – Cardiology MCQ
Inferior vena caval filter is deployed:
a) Above the renal veins
b) At the renal veins
c) Below the renal veins
d) Below the hepatic veins
Correct answer: c) Below the renal veins
Inferior vena caval (IVC) filter is usually deployed to prevent migration of venous thrombus from lower limb or pelvic veins to the right heart and the lung, with an aim to prevent pulmonary embolism. Both temporary retrievable and permanent IVC filters are available from different manufacturers. The filters have barbs or hooks to prevent migration within the IVC. The filters are usually deployed below the renal veins under fluoroscopic guidance...
