How do you treat a torn papillary muscle?
Papillary muscle rupture is generally treated with mitral valve replacement. Free-wall rupture is treated by resecting the infarcted area and closing the rupture zone with Teflon or Dacron patches or by using of biologic glues. Successful off-pump surgery (without the use of cardiopulmonary bypass) has been reported.
What happens if papillary muscles rupture?
Papillary muscle rupture is a rare and potentially fatal complication often following a myocardial infarction or secondary to infective endocarditis. Acute rupture frequently results in severe mitral valve regurgitation and subsequent acute life-threatening cardiogenic shock and pulmonary edema.
Which papillary muscle is most likely to rupture?
The posteromedial papillary muscle is twelve times more likely to rupture than the anterolateral papillary muscle because the blood supply of the two papillary muscles are different.
What is ruptured papillary muscle?
Papillary muscle rupture (PMR) is a dangerous complication that can evolve as a consequence of myocardial infarction or infective endocarditis leading to severe acute mitral or tricuspid regurgitation leading to left or right-sided heart failure.
What is MVP medical condition?
Mitral valve prolapse, also known as click-murmur syndrome, Barlow's syndrome, balloon mitral valve, or floppy valve syndrome, is the bulging of one or both of the mitral valve flaps (leaflets) into the left atrium during the contraction of the heart.
What causes papillary rupture?
The most common cause of papillary muscle rupture is secondary to myocardial infarction. This usually occurs 2 to 7 days post-ischemic event. Rupture occurs more commonly with ST-segment elevation myocardial infarctions but also occurs less frequently with non-ST segment elevation infarctions.

What type of muscle is papillary muscle?
The papillary muscles are thick bands and ridges of endocardial-lined myocardium that project into the lumen of the cardiac ventricles. They essentially represent dominant ventricular trabeculae which attach to the cusps of the atrioventricular valves via the chordae tendineae.
What is the moderator band?
The moderator band, also called the septomarginal trabecula, is a consistent structure in the morphologic right ventricle and can be helpful as a landmark in situations where the ventricles may be ambiguous (i.e. in some forms of congenital heart disease).
Where is papillary muscles located?
left ventricleIntroduction. The papillary muscles of the left ventricle (LV) are small muscular structures located within the left ventricular cavity. Although small, these muscles play an important role in the functioning of the mitral valve and the left ventricle.
What artery supplies papillary muscle?
The left circumflex or right coronary artery (depending on dominance) provides the blood supply to the postero-medial papillary muscle. Because of its single system of blood supply, this papillary muscle is particularly prone to injury from myocardial infarction.
What is the function of papillary muscles?
Background— The papillary muscles (PMs) play an important role in normal cardiac function, helping to prevent leakage through the AV valves during systole. The nature of their attachment to the heart wall can affect the understanding of their function.

What happens if the chordae tendineae rupture?
Primary chordae tendineae rupture (CTR) can lead to a total loss of tension of one of the mitral valve leaflets, which then becomes flail. This often leads to abrupt aggravation of the MR, with fainting and/or acute congestive heart failure (CHF).
What happens when chordae tendineae breaks?
Chordae tendineae rupture (CTR) is a potentially life-threatening cardiac event [1]. CTR is characterised by sudden onset, rapid progression of pulmonary edema, hypotension, and left-sided heart failure which may finally lead to severe cardiac shock or pulmonary hypertension and acute right-sided heart failure [2].
What is the role of the papillary muscles on the heart's interior?
function in heart The papillary muscles project like nipples into the cavities of the ventricles. They are attached by fine strands of tendon to the valves between the atria and ventricles and prevent the valves from opening when the ventricles contract.
What is a ruptured papillary muscle?
A papillary muscle rupture is a serious condition that occurs when the papillary muscle tears. This can also occur if there is a tear in any chordae tendineae, the tendon-like 'heart strings' that connect the papillary muscles to the atrioventricular valves.
How to treat a ruptured valve?
The most common treatment for a rupture is surgical interventions by way of valve repair or a valve replacement. Pharmaceutical interventions are used to help increase cardiac output.
How many papillary muscles are there in the heart?
There are a total of five papillary muscles within the heart. These cardiac components are within the ventricles of the heart and are connected to the two atrioventricular valves, the mitral valve, and the tricuspid valve. These valves separate the atrium from the ventricle, opening to allow blood flow into the ventricles of the heart and closing to prevent any backflow of blood into the atrium.
What muscles are responsible for preventing a collapse of the atrioventricular valves?
The papillary muscles are connected to these valves and help prevent a collapse or breakdown of the valves known as a prolapse. When these muscles work properly, they help to prevent blood flow from being forced back into the atrium through the atrioventricular valves known as valve regurgitation.
Can myocardial infarction cause prolapse?
This can affect the papillary muscles in the same manner as a myocardial infarction and cause the tissues to stop functioning well, resulting in prolapse .
How long does it take to get a thyroid scan for RAI?
Following either of the above approaches to treat a papillary thyroid cancer with RAI, a scan is obtained following the therapeutic dose in 48 to 72 hours to determine the location and percent uptake of the radioactive iodine. The strength of radioactive iodine is described in millicuries.
What is the blood test for papillary thyroid cancer?
The papillary thyroid cancer patient understands their thyroid cancer and accepts that the blood test for the blood marker for papillary thyroid cancer called thyroglobulin, will not be useful in the monitoring of their cancer since this protein is also produced by the remaining normal thyroid cells in the remaining thyroid tissue
How to tell if thyroid is cancerous?
Even prior to surgery, most central compartment lymph nodes can be well examined with high quality ultrasound to determine if they are cancerous. Here, the arrow points to an abnormal lymph node seen on ultrasound next to the thyroid gland before surgery. Abnormal lymph nodes undergo fine needle aspiration (FNA) examination to determine whether cancer is present. Some lymph nodes which lay immediately underneath the thyroid gland cannot be seen until the time of surgery and required a skilled surgeon to identify them and can then be confirmed during the surgery by a process called frozen section pathology. Warning: The linked video here is a video of an actual thyroid surgery up close, so if you are in any way squeamish about seeing an actual surgery in progress please do not follow this link!

What is the term for the removal of half of the thyroid gland?
One is removal of about half of the thyroid gland called a thyroid lobectomy . The other is removal of all of the thyroid gland and is called a total thyroidectomy. The third type of thyroidectomy is called a subtotal thyroidectomy where almost all of the thyroid gland is removed.
How long is a thyroidectomy incision?
A small incision in the lower neck is required which is about an inch in length unless the thyroid mass requires a longer length to allow it to be "delivered". The length of a total thyroidectomy incision is no longer than an incision for a thyroid lobectomy. All of the critical structures on both sides of the thyroid are maintained including all four parathyroid glands and all four nerves that provide movement (recurrent laryngeal nerves) and sensation to the voice box (superior laryngeal nerves). The lymph nodes along the side and beneath the thyroid gland are also examined during this surgery to make sure that they are not cancerous as well.
Why is thyroid hormone suppressive therapy given to papillary thyroid cancer patients?
Giving thyroid hormone to papillary thyroid cancer patients is called thyroid hormone suppressive therapy when the goal is to decrease the pituitary production of TSH.

What is the sensitivity of transthoracic echocardiography?
Transthoracic echocardiography is useful, and often the initial imaging modality utilized, in the diagnosis of PMR with a sensitivity of 65–85% [6]. The mitral apparatus is a posterior structure; therefore transesophageal echocardiography (which places the ultrasound probe closer to the valve) can offer superior visibility with a diagnostic yield between 95% and 100% [7]. The sensitivity of both echo modalities is improved with the use of color flow Doppler to measure eccentric regurgitant jets [5].
What is PMR in cardiology?
Papillary muscle rupture (PMR) frequently presents with symptoms ranging from acutely decompensated heart failure to cardiogenic shock. The most frequent scenario involves infarction upstream from the posterior descending artery (i.e. the right coronary artery in right dominant systems or the left circumflex artery in left dominant systems). Valvular competence during ventricular systole is maintained by the actions of two papillary muscles (anterolateral and posteromedial). The anterolateral muscle typically has a dual blood supply while the posteromedial muscle is supplied from only the PDA. Therefore the posteromedial muscle is more susceptible to infarction and rupture.
What is the treatment for papillary muscle rupture?
Treatment often necessitates emergent surgical intervention, with mitral valve repair (if muscle necrosis is limited) or valve replacement [2]. Both immediate and long-term outcomes are improved with concomitant coronary revascularization [3]. Herein we present two cases that demonstrate the typical presentation of acute papillary muscle rupture and remind clinicians that prompt recognition and management are critical in this uncommon but lethal complication.
How long did it take for a patient to recover from a prosthetic mitral valve?
The patient gradually recovered over the next 12 days and was successfully discharged home in good condition. Follow up echocardiogram two weeks after discharge revealed a normal functioning prosthetic mitral valve with normal Doppler flow pattern.
Which muscle is responsible for maintaining ventricular competence during ventricular systole?
Valvular competence during ventricular systole is maintained by the actions of two papillary muscles (anterolateral and posteromedial). The anterolateral muscle typically has a dual blood supply while the posteromedial muscle is supplied from only the PDA.
What are the complications of myocardial infarction?
These include left ventricular free wall rupture, rupture of the interventricular septum, and papillary muscle rupture. All involve loss of structural integrity of the infarcted tissue and are associated with extraordinarily high mortality rates if not promptly recognized and treated. Fortunately with an increasing emphasis on early revascularization coupled with improved techniques these catastrophic complications are relatively rare, representing 2.3% of acute myocardial infarctions [1].
How long does it take to die from PMR?
Once identified urgent or emergent surgery is warranted, without surgical repair approximately 90% of patients with PMR will die within one week [9]. The valve should be repaired if possible; however the tissue is often weak and friable making repair difficult or impossible. In such cases the valve should be replaced with prosthesis. Concomitant coronary revascularization (i.e. coronary artery bypass grafting) has been shown to improve both early and long-term survival and should thus be performed [10].
What is PM in myocardial infarction?
Papillary muscle (PM) rupture is a rare complication of acute myocardial infarction which carries an excessive mortality rate. Optimal outcomes require rapid diagnosis and prompt surgical referral, and in this regard, echocardiography plays a crucial role. Comprehensive echocardiographic examination …
