Project description:This paper describes the case of a 68-year-old man who presented in cardiac tamponade due to a right ventricular free wall rupture after a recent ST-segment elevation myocardial infarction. After a pericardiocentesis, the ventricular defect resolved spontaneously. The patient was managed medically and avoided surgical intervention. (Level of Difficulty: Intermediate.).

A new hybrid sutureless patch repair utilizing chitosan for left ventricle rupture after myocardial infarction: A case report.

Project description:IntroductionThere are many publications reporting the use of TachoSil sheets for sutureless repair. Trauma doctors have recently reported that chitosan-based sheets can efficiently achieve hemostasis for active bleeding.Presentation of caseAn 85-year-old man was diagnosed with left ventricle free wall rupture that caused cardiac tamponade and cardiogenic shock. Extracorporeal membrane oxygenator (ECMO) was started immediately and surgical repair was planned. Bleeding occurred from a 1-cm tear in the center of the necrotic area in the territory of the left circumflex artery. The tear was treated with a chitosan-based HemCon Bandage. After hemostasis of the myocardium was achieved, the bandage was peeled off and a patch repair was performed using collagen fleece with fibrinogen-based impregnation. His condition subsequently improved. The tracheal tube was extubated and ECMO was removed 2days after the surgery. One month later, the patient had no complications at his postoperative follow-up visit.DiscussionTo our knowledge, this is the first report of a hybrid patch repair utilizing chitosan-based sheets for a left ventricle rupture after myocardial infarction. Further studies are necessary to evaluate the short- and long-term efficacy of this procedure, and these results must be compared with those of classical surgical repairs.ConclusionThe new hybrid sutureless patch utilizing chitosan was demonstrated as safe, easy and effective.

Survival after left ventricular free wall rupture in an elderly woman with acute myocardial infarction treated only medically.

Project description:Pseudoaneurysm of the left ventricle is rare and may occur as a result of transmural myocardial infarction. The course of rupture after acute myocardial infarction varies from a catastrophic event, with an acute tear leading to immediate death (acute rupture), or slow and incomplete tear leading to a late rupture (subacute rupture). Incomplete rupture may occur when the thrombus and haematoma together with the pericardium seal the rupture of the left ventricle and may develop into a pseudoaneurysm. Early diagnosis and treatment is essential in this condition. Two-dimensional color Doppler echocardiography is the first-choice method for most patients with suspected left ventricular pseudoaneurysm (LVP) and suggests left ventricular rupture in 85% to 90% of patients. We report the case of an 87-year-old woman presenting with symptoms and findings of myocardial infarction and left ventricular free wall rupture with a pseudoaneurysm formation diagnosed by echocardiography and confirmed on CT, MRI, and NM. She received only intense medical treatment, because she refused surgery with a favorable outcome. After 24-month followup, she is in NYHA functional class II. The survival of this patient is due to the contained pseudoaneurysm by dense pericardial adhesions, related to her previous coronary bypass surgery.

Left ventriculography for posterolateral free wall rupture complicated with ST-elevated myocardial infarction.

Project description:Left ventricular free wall rupture is not a rare complication of ST-elevated myocardial infarction, and causes fatal results. This complication is often diagnosed on the basis of hemodynamic collapse and transthoracic echocardiography. We describe a case of posterolateral free wall rupture that could not be diagnosed using transthoracic echocardiography but was diagnosed using left ventriculography, mainly in the left anterior oblique view. We were unsuccessful in preventing patient fatality because of late diagnosis. Therefore, we must keep in mind the limitation of each diagnostic modality. <Learning objective: A posterior wall rupture sometimes shows no pericardial effusion on transthoracic echocardiography. Left ventriculography may be a useful modality as a last resort to detect posterior wall rupture. In this situation, the right anterior oblique view may not demonstrate the contrast extravasation of a posterior wall rupture, and the left anterior oblique view may be useful in detecting it.>.
