Fontan procedure
|

|
|
Hypoplastic L heart syndrome
|
a generic term used to describe a group of closely related cardiac anomalies characterized by underdevelopment of L cardiac chambers, in association w/tresia or stenosis of aortic and/or the mitral orifices, and hypoplasia of aorta. The term should be restricted to those w/ normally connected hearts w/ concordant AV and ventriculoarterial connections. Hypoplastic L heart syndrome is characterized by duct-dependent systemic blood flow and so tends to present w/ severe symptoms w/in the 1st week of life, as ductal constriction occurs. Untreated, the disease is almost uniformly fatal in infancy
|
|
Mustard or a Senning procedure
|
Systemic venous return is diverted thru the mitral valve into the subpulm. LV, and the pulm. venous return is rerouted thru the tricuspid valve into the subaortic RV. By virtue of this repair, the morphological RV is left to support the systemic circulation.
|
|
cc-TGA is
|
When there is the usual atrial arrangement, systemic venous blood passes from the R atrium thru a mitral valve to a LV and then to the posteriorly located pulm. artery. Pulm. venous blood passes from the L atrium thru a tricuspid valve to a L-sided RV and then to an anterior, L-sided aorta. The circulation is thus “physiologically” corrected, but the morphological RV supports the systemic circulation. Associated anomalies occur in up to 95 % of pts and consist of VSD (75 %), pulm. or subpulm. stenosis (75 %), and L-sided (tricuspid and often “Ebstein-like”) valve anomalies (>75 %
|
|
Total anomalous pulm. venous return:
|
supracardiac, = pulm. veins drain either via the vertical vein to anomal vein (A) or directly to SVC w/ orifice close to orifice of azygos vein (B). (C), Drainage into R atrium via coronary sinus. (D), Infracardiac drainage via vertical vein into portal vein or IVC.
|
|
Ebstein anomaly
|
apical displacement of septal tricuspid leaflet in conjunction with leaflet dysplasia. Many, but not all, have associated displacement of the posterior mural leaflet, with the anterior leaflet never being displaced. Although the anterior leaflet is never displaced apically, it may be adherent to the free wall of the RV, causing RVOT obstruction. The displacement of the tricuspid results in “atrialization” (functioning as an atrial chamber) of the inflow tract of the RV and consequently produces a variably small, functional RV. Associated anomalies include PFO or ASD in approximately 50% of pts; accessory conduction pathways in 25 percent (usually right sided); and, occasionally, varying degrees of RVOT obs, VSD, aortic coarct, PDA, or mitral valve disease. LV abnorm. resembling noncompaction syndrome have also been

|
|
When does parvus and tardus occur even with mild aortic stenosis?
|

|
|
In addition to aortic regurgitaiton, which other processes cause rapid upstroke
and widened pulse pressure?e |
The most common are the hyperkinetic heart syndromes (high output states). These include
anemia, fever, exercise, thyrotoxicosis, pregnancy, cirrhosis, beriberi, Paget�s disease, arteriovenous fistulas, patent ductus arteriosus, aortic regurgitation, and anxiety�all typically associated with rapid ventricular contraction and low peripheral vascular resistance. |
|
What is pulsus alternans? and what does it signify?
|
Pulsus alternans is the alternation of strong and weak arterial pulses despite regular rate and
rhythm. First described by Ludwig Traube in 1872, pulsus alternans is often associated with alternation of strong and feeble heart sounds (auscultatory alternans). Both indicate severe left ventricular dysfunction (from ischemia, hypertension, or valvular cardiomyopathy), with worse ejection fraction and higher pulmonary capillary pressure. Hence, they are often associated with an S3 gallop |
|
What is Duroziez’s double murmur
|
Duroziez�s is a to-and-fro double murmur over a large central artery�usually the femoral,
but also the brachial. It is elicited by applying gradual but firm compression with the stethoscope�s diaphragm. This produces not only a systolic murmur (which is normal) but also a diastolic one (which is pathologic and typical of AR). Duroziez�s has 58% to 100% sensitivity and specificity for AR. |
|
What is Corrigan's pulse?
|
Corrigan's is one of the various names for the bounding and quickly collapsing pulse of aortic
regurgitation, which is both visible and palpable. Other common terms for this condition include water hammer, cannonball, collapsing, or pistol-shot pulse. It is best felt for by elevating the patient�s arm while at the same time feeling the radial artery at the wrist. Raising the arm higher than the heart reduces the intraradial diastolic pressure, collapses the vessel, and thus facilitates the palpability of the subsequent systolic thrust.u��ޙ |
|
What is the Levine system for grading the intensity of murmurs?
|
1/6: a murmur so soft as to be heard only intermittently and always with concentration and
effort. Never immediately 2/6: a murmur that is soft but nonetheless audible immediately and on every beat 3/6: a murmur that is easily audible and relatively loud 4/6: a murmur that is relatively loud and associated with a palpable thrill (always pathologic) 5/6: a murmur loud enough that it can be heard even by placing the edge of the stethoscope's diaphragm over the patient's chest 6/6: a murmur so loud that it can be heard even when the stethoscope is not in contact with the chest, but held slightly above its surface |
|
What factors may suggest severe aortic stenosis? (In setting of a murmur?)
|
Murmur intensity and timing (the louder and later peaking the murmur, the worse the
disease) & A single S2 & Delayed upstroke/reduced amplitude of the carotid pulse (pulsus parvus and tardus)g |
|
What is isometric hand grip, and what does it do to AS and mitral regurgitation (MR) murmurs?
|
Isometric hand grip is carried out by asking the patient to lock the cupped fingers of both hands
into a grip and then trying to pull them apart. The resulting increase in peripheral vascular resistance intensifies MR (and ventricular septal defect) while softening instead AS (and aortic sclerosis). Hence, a positive hand grip argues strongly in favor of MR. |
|
What is the Gallavardin phenomenon?
|
One noticed in some patients with AS, who may exhibit a dissociation of their systolic murmur
into two components: & A typical AS-like murmur (medium to low pitched, harsh, right parasternal, typically radiated to the neck, and caused by high-velocity jets into the ascending aorta) & A murmur that instead mimics MR (high pitched, musical, and best heard at the apex) This phenomenon reflects the different transmission of AS: its medium frequencies to the base and its higher frequencies to the apex. The latter may become so prominent as to be misinterpreted as a separate apical ��cooing�� of MR |
|
What are the characteristics of the MR murmur?urmur?
|
It is loudest at the apex, radiated to the left axilla or interscapular area, high pitched, plateau,
and extending all the way into S2 (holosystolic). S2 is normal in intensity but often widely split. If the gradient is high (and the flow is low), the MR murmur is high pitched. Conversely, if the gradient is low (and the flow is high) the murmur is low pitched. In general, the louder (and longer) the MR murmur, the worse the regurgitation.� |
|
What are the characteristics of the acute MR murmur?
|
The acute MR murmur tends to be very short, and even absent, because the left atrium and
ventricle often behave like a common chamber, with no pressure gradient between them. Hence, in contrast to that of chronic MR (which is either holosystolic or late systolic), the acute MR murmur is often early systolic (exclusively so in 40% of cases) and is associated with an S4 in 80% of the patients.ng |

What is a mammary souffle�
|
Not a fancy French dish but a systolic-diastolic murmur heard over one or both breasts in
late pregnancy and typically disappearing at end of lactation. It is caused by increased flow along the mammary arteries, which explains why its systolic component starts just a little after S1. It can be obliterated by pressing (with finger or stethoscope) over the area of maximal intensity��S |
|

& R/S wave ratio in V1 > 1 3. |
|
What criteria are used to diagnose left atrial enlargement (LAE)?
|

|
|
What is the normal rate of a junctional rhythm?
|
The normal rate is 40 to 60 beats/min. Rates of 61 to 99 beats/min are referred to
as accelerated junctional rhythm, and rates of 100 beats/min or higher are referred to as junctional tachycardia.�� |
|
How can one distinguish a junctional escape rhythm from a ventricular escape
rhythm in a patient with complete heart block? |
Junctional escape rhythms usually occur at a rate of 40 to 60 beats/min and will usually be
narrow complex (unless the patient has a baseline bundle branch block), whereas ventricular escape rhythms will usually occur at a rate of 30 to 40 beats/min and will be wide complex.� |
|
What are the ECG findings in pericarditis?ythm?
|
The first findings are believed by some to be PR segment depression caused by repolarization
abnormalities of the atria. This may be fairly transient and is often not present by the time the patient is seen for evaluation. Either concurrent with PR segment depression or shortly following PR segment depression, diffuse ST segment elevation occurs (see ECG example in Chapter 53 on Pericarditis). At a later time, diffuse T-wave inversions may develop |
|
What ECG findings may be present in pulmonary embolus?
|
& Sinus tachycardia (the most common ECG finding)
& Right atrial enlargement (P pulmonale)�tall P waves in the inferior leads & Right axis deviation & T wave inversions in leads V1-V2 & Incomplete right bundle branch block (IRBBB) & S1Q3T3 pattern�an S wave in lead I, a Q wave in lead III, and an inverted T wave in lead III. Although this is only occasionally seen with pulmonary embolus, it is said to be quite suggestive that a pulmonary embolus has occurred.�N |
|
What are the common radiographic signs of congestive heart failure?ent?
|
Enlarged cardiac silhouette
& Left atrial enlargement & Hilar fullness & Vascular redistribution & Linear interstitial opacities (Kerley�s lines) & Bilateral alveolar infiltrates & Pleural effusions (right greater than left��� |
|
What is vascular redistribution? When does it occur in congestive heart failure
|
Vascular redistribution occurs when the upper-lobe pulmonary arteries and veins become larger
than the vessels in the lower lobes. The sign is most accurate if the upper lobe vessels are increased in diameter greater than 3 mm in the first intercostal interspace. It usually occurs at a pulmonary capillary occlusion pressure of 12–19 mm Hg. As the pulmonary capillary occlusion pressure rises above 19 mm Hg, interstitial edema develops with bronchial cuffing, Kerley’s B lines, and thickening of the lung fissures. Vascular redistribution to the upper lobes is probably most consistently seen in patients with chronic pulmonary venous hypertension (mitral valve disease, left ventricular dysfunction) because of the body’s attempt to maintain more normal blood flow and oxygenation in this area. Some authors believe that vascular redistribution is a cardinal feature of congestive heart failure, but it may be a particularly unhelpful sign in the ICU patient with acute congestive failure. In these patients, all the pulmonary arteries look enlarged, making it difficult to assess upper and lower vessel size. In addition, the film is often taken supine, which can enlarge the upper lobe pulmonary vessels because of stasis of blood flow and not true redistribution. |
|
How does LV dysfunction and RV dysfunction lead to pleural effusions?
|
LV dysfunction causes increased hydrostatic pressures, which lead to interstitial edema
and pleural effusions. Right pleural effusions are more common than left pleural effusions, but the majority are bilateral. & RV dysfunction leads to system venous hypertension, which inhibits normal reabsorption of pleural fluid into the parietal pleural lymphatics |
|
What is Westermark’s sign?
|
Westermark’s sign is seen in patients with pulmonary embolism and represents an area
of oligemia beyond the occluded pulmonary vessel. If pulmonary infarction results, a wedgeshaped infiltrate may be visible ( |

|
Which cardiac patients should never get
pregnant? |
1 Those with significant pulmonary hypertension (pulmonary
vascular resistance >2/3 of systemic), especially cyanotic patients and those with Eisenmenger reaction (maternal mortality ~50%) and those with residual pulmonary hypertension after e.g. VSD closure. NB: Even women with modest pulmonary vascular disease ~1/2 systemic are at risk of death. 2 Those with grade 4 systemic ventricular function (EF <20%).� |
|
Which cardiac patients should undergo
elective Caesarean section? |
1 Those with independent obstetric indications.
2 Caesarean section should be strongly considered for the following women: � Those with mechanical valves, especially tilting disc in the mitral position.

An elective section is performed at 38 weeks� gestation, replacing the warfarin with unfractionated heparin for the minimum time possible � Severe aortic or mitral stenosis |
|
Which women should not get pregnant until operated upon?
|
1 Marfan�s syndrome patients with aortic aneurysm/dilated
aortic root. 2 Those with severe left sided obstructive lesions (AS, MS, coarctation). |
|
A patient is on life-long warfarin and wishes to
become pregnant. How should she be managed?� |
The use of warfarin during pregnancy is associated with a low
risk of maternal complications1 but it readily crosses the placenta and embryopathy can follow exposure between 6�12 weeks� gestation, the true incidence of which is unknown. A single study has reported that a maternal warfarin dose 5mg is without this embryopathy risk.2 As pregnancy progresses, the immature vitamin K metabolism of the fetus can result in intracranial haemorrhage even when the maternal INR is well controlled. In addition, a direct CNS effect of warfarin has been described, resulting in structural abnormalities. Conversion to heparin in the final few weeks of pregnancy is recommended to prevent the delivery of, what is in effect, an anticoagulated fetus.3 |
|
What are the (6) indications for surgical
management of endocarditis? |
1. Congestive heart failure
2. Persistent sepsis (after 3-5 days ABX with blood sterility or lack of clinical improvement after one week) 3. Recognised virulence of the infecting organism (certain SA and most fungal..With prosthetic valve endocarditis, streptococcal tissue valve infections involving only the leaflets can be cleared in 80% with antibiotic therapy alone; however, mechanical or tissue valve infections involving the sewing ring generally require valve replacement. If echocardiography demonstrates a perivalvular leak, annular extension, or a large vegetation,early operation is necessary) 4. Extravalvular extension 5. Peripheral embolisation 6. Cerebral embolisation |
|
Which cardiac abnormalities greatly increase the risk of endocarditis?
|
patent ductus arteriosus, prosthetic valves, hypertrophic
cardiomyopathy, aortic valve disease or previous endocarditis |
|
ASD Indications for closure include:
|
symptoms (exercise intolerance,
arrhythmias), right heart volume overload on echocardiography, the presence of a significant shunt (>2:1) or cryptogenic cerebrovascular events, especially associated with aneurysm of the oval foramen and right to left shunting demonstrated on contrast echocardiography during a Valsalva manoeuvre |
|
How do I follow up a patient who has had
correction of aortic coarctation? What should I look for and how should they be managed? |

|
family history of sudden deaths, recurrent syncope, non-sustained ventricular tachycardia and an abnormal blood pressure drop during exericise, LV thickness > 3 cm,
|
|
What is the medical therapy for HCM?
|
In those without
obstruction, the choice is between either a beta blocker or a calcium antagonist, such as high dose verapamil (up to 480mg/day). In those with obstruction a beta blocker with or without disopyramide is usually the first choice for those patients with outflow obstruction (~25% of patients). refractory symptoms may be candidates for invasive treatment modalities such as dual chamber pacing with a short AV delay, alcohol septal ablation or surgical myectomy. |
