After performing an autopsy, the Chicago medical examiner announced that this man's sudden death definitively was not due to the oppressive heat and humidity that caused significant problems among many runners that day and which eventually caused organizers to stop the race , but instead was due to " mitral valve prolapse " MVP.

This verdict no doubt brought very great relief to the local officials responsible for going ahead with the race despite horrific weather conditions, and who thanks to the autopsy conclusions were now officially off the hook regarding this man's death.

Obviously, we can have no way of knowing the actual cause of this unfortunate runner's death. However, the Chicago medical examiner's confident pronouncement created at least some degree of panic among up to 75 million Americans who by some estimates might also have MVP. And for a few weeks, American cardiologists were flooded with worried phone calls. So, the question bears asking: Does MVP really cause sudden death? In mitral valve prolapse, the leaflets of the mitral valve bulge prolapse into the left atrium like a parachute when the heart contracts.

Sometimes mitral valve prolapse causes blood to leak back into the atrium from the ventricle, which is called mitral valve regurgitation. Mitral valve prolapse occurs when the flaps leaflets of the heart's mitral valve bulge prolapse like a parachute into the heart's left upper chamber left atrium as the heart contracts. Mitral MY-trul valve prolapse sometimes leads to blood leaking backward into the left atrium, a condition called mitral valve regurgitation.

In most people, mitral valve prolapse isn't life-threatening and doesn't require treatment or changes in lifestyle. Some people with mitral valve prolapse, however, require treatment. Although mitral valve prolapse is usually a lifelong disorder, many people with this condition never have symptoms.

When diagnosed, people may be surprised to learn that they have a heart condition. When signs and symptoms do occur, it may be because blood is leaking backward through the valve. Mitral valve prolapse symptoms can vary widely from one person to another.

They tend to be mild and develop gradually. Symptoms may include:. If you think you have any of the above symptoms, make an appointment with your doctor. Many other conditions cause the same symptoms as mitral valve prolapse, so only a visit to your doctor can determine the cause of your symptoms. If you're having chest pain and you're unsure if it could be a heart attack, seek emergency medical care immediately. If you've already been diagnosed with mitral valve prolapse, see your doctor if your symptoms worsen.

The mitral valve controls the flow of blood between the upper and lower chambers of the left side of the heart. When your heart is working properly, the mitral valve closes completely when the heart pumps and prevents blood from flowing back into the upper left chamber left atrium. But in some people with mitral valve prolapse, one or both of the mitral valve leaflets have extra tissue or stretch more than normal, which causes them to bulge like a parachute into the left atrium each time the heart contracts.

The bulging may keep the valve from closing tightly. Coronary artery disease was ruled out invasively Fig. High-sensitivity troponin was repeatedly negative. Pulmonary embolism and subarachnoid hemorrhage were ruled out by means of CT. Thus, no obvious cause for the ventricular fibrillation could be determined initially. Ventricular fibrillation being terminated with an external defibrillation a.

Episodes of ventricular arrhythmia detected during monitoring c. Atrial fibrillation with tachycardia d. Physical examination on admission: Obese year-old woman BMI Heart, lungs, and abdomen unremarkable. Laboratory studies: Complete blood count: unremarkable.

Fast echocardiography: Normal systolic right and left ventricular systolic function, severe mitral regurgitation, no pericardial effusion. Controlled ventilation was stopped on the fourth day. Except for a hypoactive delirium, which was adequately controlled by administration of a neuroleptikum, no neurological deficits were manifested. However, we have registered recurrent ventricular salves during monitoring Fig.

In addition, we registered a short-lasting atrial fibrillation with spontaneous termination Fig. Therefore, oral anticoagulation was initiated. Follow-up echocardiography showed a significant mitral valve insufficiency with preserved left ventricular pump function.

The left ventricle demonstrated mild endsystolic and enddiastolic dilatation. The lateral mitral annular velocities was quantified with Doppler tissue imaging. TEE demonstrating bileaflet mitral valve prolapse a. Severe eccentric mitral regurgitation in TEE c. Dilated left atrium and myxomatous degeneration of the mitral valve d. Transesophageal echocardiography was performed to evaluate the mitral valve more precisely. Especially the PML showed thickening and myxomatous changes Fig.

The tendinous chordae appeared to be intact. For further clarification of the arrhythmogenic event, we ordered a CMR. The right ventricle showed no pathology by echocardiography and CMR. LGE identified in papillary muscle b. Regarding the severe mitral valvular insufficiency due to the MVP, the case was discussed in the heart team.

The patient showed regression of the delirium and an increasing mobility. After implantation of an ICD device Fig. A cardio-neurological rehabilitation was organized. X-Ray showing a single-chamber ICD a. Detection of a ventricular tachycardia and termination with an affectiv shock b. Two factors are considered fundamental for the occurrence of SCD in patients with MVP: LV myocardial fibrosis substrate and complex ventricular ectopy trigger.

Perhaps a consequence of mechanical traction exerted by the prolapsing leaflet, the fibrosis is most often localized to the posterior base of the left ventricle or the papillary muscles, which are most susceptible to the mechanical stretch forces exerted by the billowing leaflets [ 3 ].

The prolapsing mitral valve exercises traction on the papillary muscles, activating the local stretch receptors and causing membrane depolarization of the nerve endings with abnormal mechanoelectrical feedback to the central nervous system causing VT or VF [ 4 ]. Meanwhile some studies and case reports have indicated that mitral valve prolapse may be a trigger for ventricular fibrillation. Thus, there is evidence for a significantly increased risk of SCD as well as risk for ventricular tachycardia in patients with MVP [ 2 ].

This group has an approximately annual SCD risk of 0. The reason for this observation is unknown. Premature ventricular contractions PVC are observed in the general population of MVP patients, with insignificantly difference between patients with and without SCD [ 9 ].

This constellation could be explained by a mechanical overload of the left ventricle in this area due to the defective functioning mitral valve [ 10 ]. Further explorations are required to confirm these findings. The echocardiography allows a precise evaluation of the mitral valve.

In addition to estimating the severity of mitral regurgitation and its mechanism, the echocardiography permits screening of risk parameters for sudden cardiac death due to MVP. Researchers solidify link between mitral valve prolapse, sudden cardiac death. Around the web Radiology Business.
