Non-ischemic rupture of the posteromedial papillary muscle due to Streptococcus agalactiae endocarditis.

ABSTRACT: Papillary muscle rupture is usually caused by myocardial infarction although rare cases of non-ischemic etiology have also been described. Among these, infective endocarditis represents an important cause. Herein, we report a case due to Streptococcus agalactiae involving the posteromedial papillary muscle.

Learning objective

Non-ischemic papillary muscle rupture should be suspected when there is no evidence of atherosclerotic coronary artery disease. In the febrile patient, infective endocarditis should be considered in the differential diagnosis.

Acute posteromedial papillary muscle rupture secondary to aortic valve endocarditis: a case report.

Project description:BackgroundAcute papillary muscle (PM) rupture due to infective involvement has been recognized as a complication of infective endocarditis. However, there is very limited literature describing the rupture of the posteromedial PM in primary aortic valve endocarditis without aortic root abscess. This report highlights the aetiology of the PM rupture in the setting of primary aortic valve endocarditis and the importance of a multidisciplinary approach.Case summaryAn 81-year-old man without any heart failure symptoms presented with fever and loss of vision in his left eye. Initial echocardiography revealed moderate aortic valve regurgitation due to a perforated right coronary cusp without aortic root abscess, and his blood cultures were positive for Group G Streptococci. During adequate antibiotic therapy, he developed acute severe mitral regurgitation secondary to posteromedial PM rupture. Following emergent aortic and mitral valve replacement using bioprosthetic valves, he made excellent progress on a 6-week course of intravenous antibiotics.DiscussionThe echocardiography and the histological findings suggested that the main cause of PM rupture was most likely a metastatic focus of infection from the aortic valve via a regurgitant jet. Successful treatment of this fatal complication includes early diagnosis and prompt surgical intervention by a multidisciplinary approach.

Acute mitral valve regurgitation secondary to papillary muscle rupture due to infective endocarditis.

Project description:BackgroundPapillary muscle rupture due to infective endocarditis is a rare event and proper management of this condition has not been described in the literature. Our case aims to shed light on treatment strategies for these patients using the current guidelines.Case presentationThis case presents a 58-year-old male with acute heart failure secondary to papillary muscle rupture. He underwent an en bloc resection of his mitral valve with a bioprosthetic valve replacement. Specimen pathology later showed necrotic papillary muscle due to infective endocarditis. The patient was further treated with antibiotic therapy. He recovered well post-operatively and continued to do well after discharge.ConclusionIn patients who present with papillary muscle rupture secondary to infective endocarditis, clinical symptoms should drive the treatment strategy. Despite the etiology, early mitral valve surgery remains treatment of choice for patients who have papillary muscle rupture leading to acute heart failure. Culture-guided prolonged antibiotic treatment is vital in this category of patients, especially those who have a prosthetic valve implanted.

Anterior Papillary Muscle Rupture due to Acute Myocardial Microinfarction of the Small High Lateral Branch

Project description:Papillary muscle rupture is a catastrophic condition, of which most cases manifest posterior papillary muscle rupture. Anterior papillary muscle rupture is a rare condition. Particularly, anterior papillary muscle rupture due to acute myocardial microinfarction of the small high lateral branch is extremely rare. Since papillary muscle rupture can occur even in such a small branch or small area due to myocardial infarction, echocardiographic and/or ventriculographic confirmation is essential in cases of sudden worsening of heart failure. Herein, we report the case of anterior papillary muscle rupture with a good outcome. A 61-year-old man was admitted to our hospital with cardiogenic shock. Echocardiography revealed severe mitral regurgitation due to papillary muscle rupture. Coronary angiography demonstrated high-grade stenosis in the high lateral branch. However, no other significant stenoses were found. Emergency mitral valve replacement was performed. The patient was discharged 19 days after surgery without any complications.

Mitral valve surgery for ischemic papillary muscle rupture: outcomes from the Japan cardiovascular surgery database.

Project description:BackgroundIschemic papillary muscle rupture (PMR) is a catastrophic complication following acute myocardial infarction (AMI). We evaluated early outcomes of PMR by using data from the Japan Cardiovascular Surgery Database, a nationwide Japanese registry.MethodsWe retrospectively analyzed data from 196 patients diagnosed with PMR following AMI in Japan between January 2014 and December 2017. Risk factors for operative mortality and severe complications following mitral valve surgery were analyzed.ResultsThe 30-day and hospital mortality rates were 20% and 26%, respectively. Chronic hemodialysis, abrupt rupture after AMI, resuscitation before surgery, and preoperative venoarterial extracorporeal membrane oxygenation were associated with mortality. Mitral valve replacement was chosen mainly (90%) for surgical correction of mitral regurgitation in these patients. There was no significant difference in short-term outcomes between mitral valve replacement versus mitral valve repair, despite non-matched characteristics in background between the treatment groups. Concomitant coronary artery bypass grafting had no impact on short-term outcomes.ConclusionsInformation derived from the nationwide database of patients with AMI-associated PMR show that PMR is a rare condition in the modern era. However, PMR is a severe disease with a mortality rate as high as 26%. The severity of the condition is associated with the risk for poor outcomes.

Percutaneous mitral valve repair with MitraClip XTR for acute mitral regurgitation due to papillary muscle rupture.

Project description:Papillary muscle rupture is an infrequent and highly morbid mechanical complication of acute myocardial infarction. Surgical repair or replacement is traditionally considered first-line therapy. However, many of these patients present in extremis with prohibitively high surgical risk. Repair of mitral regurgitation with the MitraClip device (Abbot Vascular, Menlo Park, CA, USA) is an established therapy to treat degenerative and functional mitral regurgitation. We present a case of successful repair of severe mitral regurgitation due to papillary muscle rupture in the setting of acute myocardial infarction. A two-clip strategy resulted in mild residual mitral regurgitation with resolution of cardiogenic shock and refractory hypoxemia requiring veno-venous extracorporeal membrane oxygenation. Six-month follow-up echocardiogram identified durable results with mild mitral regurgitation and left ventricular ejection fraction of 63 %. Our case demonstrates that percutaneous mitral valve repair with MitraClip is a well-tolerated procedure that can provide acute and long-term benefit for patients with acute mitral regurgitation due to papillary muscle rupture who are at prohibitively high surgical risk. <Learning Objective: Our case illustrates the role of MitraClip in acute mitral regurgitation due to papillary muscle rupture in cardiogenic shock as an alternative to surgical intervention in extremely high-risk patients.>.

Streptococcus agalactiae endocarditis presenting as acalculous cholecystitis in a previously well woman.

Project description:This case report describes the unusual presentation of a previously very well woman with Streptococcus agalactiae endocarditis in the emergency department. History, examination and preliminary laboratory and radiological investigations supported a diagnosis of acalculous cholecystitis, for which she was given intravenous broad spectrum antimicrobial therapy. One day following admission, the patient deteriorated and became unresponsive. Subsequent MRI of the brain revealed multiple bihemispheric cerebral emboli and a large, mobile mitral valve thrombus was visualised on her transoesophageal echocardiogram. S agalactiae was cultured from venous blood samples and her antimicrobial cover was adjusted accordingly. Despite her presumed guarded prognosis, this patient made a remarkable recovery. To our knowledge, the association of S agalactiae endocarditis with acalculous cholecystitis has not been previously described.
