Q

ACE/ARB strategy in CHF

A

The ATLAS trial examined the effects of low-dose versus high-dose ACE inhibitor therapy (lisinopril) in patients with systolic heart failure and found no difference in overall mortality; however, high-dose lisinopril was associated with a significant reduction in the composite endpoint of mortality and hospitalizations from heart failure and for any cause.

On the basis of these results, the general consensus is to uptitrate ACE inhibitors to maximal doses or until the onset of symptomatic hypotension.

Many physicians do not recommend increasing the dosage once the creatinine level rises to 2.5 mg/dL (221 μmol/L) or the estimated glomerular filtration rate falls below 30 mL/min/1.73 m2. The estimated glomerular filtration rate should be monitored for decline during uptitration of ACE inhibitor or angiotensin receptor blocker (ARB) therapy and should be rechecked before discontinuation of these drugs, as other conditions or drugs may confound the assessment of kidney function

Giant cell myocarditis is also associated with an increased incidence of high-grade atrioventricular block and ventricular arrhythmias. Unlike in acute myocarditis, aggressive immunosuppressive therapy has some benefit and should be initiated in these patients

For this reason, patients with acute heart failure unresponsive to usual care or with accompanying arrhythmias should undergo endomyocardial biopsy for diagnosis. Initial biopsy findings may be negative because of the patchy nature of the inflammation.

Q

Aflutter does not terminate with adenosine ____ (T/F)

A

True

Tachycardias that terminate with adenosine are typically AV node dependent (AVNRT and AVRT), whereas continued atrial activity (P waves) during AV block is consistent with atrial flutter or atrial tachycardia

AVNRT (Most common cause of SVT) is the result of a reentrant circuit within the AV node that uses both the fast and slow pathways. - No p waves, short RP
- Re-entry pathway
-AVNRT may be terminated with vagal maneuvers or adenosine. AV nodal blocking therapy with β-blockers or calcium channel blockers is used to prevent recurrent AVNRT. In patients with recurrent AVNRT and patients who do not tolerate or prefer to avoid long-term medical therapy, catheter ablation should be considered. Catheter ablation of AVNRT has a high success rate, although it is associated with a 1% risk for injury to the AV node necessitating pacemaker implantation.

A

HOCM

62
Q

Common causes of aortic stenosis_______

A

Aging, rheumatic heart disease (with mitral valve disease, never alone), prior chest radiation

63
Q

When the valve data from ECHO/clinical symptoms are non-concordant with low EF in suspected aortic stenosis_____

A

Dobutamine ECHO : Is low flow due to LV dysfunction with pseudostenosis or actual AS

With pseudostenosis, dobutamine increases cardiac output and the opening forces on the aortic valve, causing the valve area to increase out of the severe range. With true aortic stenosis, the calculated valve area remains in the severe range with dobutamine administration, and the aortic valve gradient and velocity increase with increased stroke volume.

Further evaluation with cardiac catheterization, during which the cardiac output and the gradient across the aortic valve can be measured, is required when there are discrepancies between the findings on physical examination and the echocardiographic results in symptomatic patients being considered for surgery.

64
Q

In patients with ______ the characteristic physical findings include a late-peaking systolic murmur, a diminished or absent aortic component of the S2, and a delay in the carotid upstroke (pulsus tardus) that may be accompanied by a decreased pulse amplitude

A

A

TAVR is currently indicated for symptomatic patients with trileaflet aortic stenosis who are at intermediate or high surgical risk and who do not have concomitant severe aortic regurgitation.

In select cases, balloon valvuloplasty may be used to bridge patients to therapy, ideally cath before surgical correction

68
Q

Criteria for_____ include a jet width that occupies 65% of the LV outflow tract or more, vena contracta greater than 0.6 cm, holodiastolic flow in the descending aorta, regurgitation volume of 60 mL or more, and effective regurgitant orifice area of 0.3 cm2 or greater

72
Q

findings of ______when the valve is pliable include a tapping LV impulse in the precordium, a loud S1, an increased pulmonic component of S2, a diastolic opening snap, and a diastolic rumble or low-pitched murmur at the apex

A

mitral stenosis

Rarely ever needs preprocedural cath, in contrast to aortic valve disease

In patients with a discrepancy between the clinical findings and the echocardiographic findings, stress echocardiography with pharmacologic or physical stressors should be pursued to assess the response of the mitral gradient and pulmonary pressures.

73
Q

The procedure of choice for patients with significant rheumatic mitral stenosis and a pliable mitral valve is______

A

percutaneous balloon mitral commissurotomy (PBMC).

PBMC is indicated for symptomatic patients with severe mitral stenosis and favorable valve morphology. PBMC may be considered in asymptomatic patients with critical mitral stenosis when the valve area is less than 1.0 cm2

In patients with LA thrombus, moderate mitral regurgitation, or a severely calcified valve, PBMC should not be performed.

74
Q

______ should be performed in patients with severe symptoms (New York Heart Association functional class III or IV) and a nonpliable valve or concomitantly in patients undergoing other cardiac surgical procedures.

A

Surgery for mitral stenosis, also in situations with mod regurg/severe calcification (pliability), LA thrombus

75
Q

Q

HOCM patients require ICD in the following scenarios ____

A

1) Sudden death family history <50
2) Ventricular thickness >30mm
3) Syncope episode
4) EF<50%

Tx: Volume optimization (avoid low preload) , b blocker, avoid PDE3/5 and nitrates

Invasive treatment of obstruction with open surgical septal myectomy or catheter-based alcohol septal ablation should be considered in patients who have moderate to severe symptoms of obstruction despite maximal medical therapy with a residual resting or provocable LVOT gradient of 50 mm Hg or greater, or in patients with recurrent syncope not related to arrhythmia

Surveillance: TTE is recommended every 1 to 2 years to assess for mitral regurgitation and changes in LV hypertrophy, function, and degree of obstruction.

First-degree relatives of patients with HCM should undergo evaluation with ECG and echocardiography and be offered genetic testing if a sarcomeric mutation is identified in the proband

83
Q

The electrocardiogram paradoxically demonstrates low QRS voltage and a “pseudoinfarct” pattern: Q waves in the anteroseptal leads without regional wall motion abnormalities on echocardiogram is suggestive of _________

A

Cardiac amyloid

cardiac amyloidosis should be suspected in Black patients older than 50 years who have left ventricular wall thickening that is not explained by loading conditions (for example, hypertension or aortic stenosis) and present with heart failure or features of diastolic dysfunction

84
Q

Restrictive cardiomyopathy versus constrictive pericarditis can be differentiated by: _______

A

Restrictive cardiomyopathy is distinguished from constrictive pericarditis by an elevated B-type natriuretic peptide level and concordant rise and fall of left and right systolic pressures with respiration.

restrictive physiology: the elevated B-type natriuretic peptide level (often <100 pg/mL [100 ng/L] in constrictive pericarditis), the presence of severe pulmonary hypertension, the absence of pericardial thickening on cardiac magnetic resonance imaging, and the presence of delayed enhancement of myocardium consistent with myocardial fibrosis on cardiac magnetic resonance imaging

Restrictive cardiomyopathy must be differentiated from constrictive pericarditis because surgical pericardiectomy may relieve symptoms and prolong life in patients with constriction.

85
Q

cardiac myxoma most often found____, versus angiosarcoma found in

A

L atrium

R atrium

Angiosarcomas are highly vascular tumors, and CT or CMR imaging with contrast may help differentiate an angiosarcoma from a right atrial myxoma. - More dangerous, but myxoma can also have embolic phenomena

Papillary fibroelastomas are small, independently mobile cardiac tumors that are typically attached to the left-sided valvular endocardium by a stalk : 8th decade of life, higher embolic phenomena

86
Q

Electrocardiographic changes of ___________ Concave ST-segment elevation is present in most of the leads (arrowheads). The PR segment is depressed in all leads except aVR

A

Acute pericarditis

Tx: aspirin (750-1000 mg) or NSAIDs (ibuprofen 600 mg) every 8 hours for 1 to 2 weeks. Colchicine (0.5 mg once or twice daily for 3 months) is recommended as adjunctive therapy to shorten the duration of symptoms and reduce the chances of treatment failure or recurrence.

Anything after 3 months = chronic

Glucocorticoid therapy is reserved for patients with recurrent, incessant, or chronic pericarditis despite standard therapy (including patients with uremic pericarditis not responsive to intensive dialysis); patients with contraindications to NSAID therapy; and patients with autoimmune-mediated pericarditis. Prednisone should be initiated at a dosage of 0.25 mg/kg to 0.5 mg/kg and continue for 3 months.

89
Q

______ is characterized by mobile, redundant atrial septal tissue that is often associated with a PFO.

A

90
Q

Ostium secundum defects, the most common type of ASDs (75% of cases), are located in the mid portion of the atrial septum and are usually isolated anomalies. Located in the lowest portion of the atrial septum, ostium primum defects (15%–20% of ASDs) are a component of endocardial cushion defects.

A

ASDs may be suspected in patients with unexplained right heart enlargement or atrial arrhythmias. Atrial fibrillation is a common finding in adults with an ASD

Remember ostium primum has associated additional defects: first degree AV block (conduction system), mitral regurgitation, primum has to be surgically closed not percutaneous device

main indications for ASD closure include right-sided cardiac chamber enlargement or symptoms of dyspnea; closure is reasonable for orthodeoxia-platypnea syndrome and also before pacemaker placement because of the increased risk for systemic thromboembolism

91
Q

Percutaneous device closure vs surgical ASD repair
