Rupture of papillary muscle during dobutamine stress echocardiography

Mitral valve repair for post-myocardial infarction papillary muscle rupture

“…All patients in this study experienced partial PMR. When PMR is partial or incomplete, established repair techniques, such as quadrangular or triangular resection of a prolapsing mitral valve leaflet segment combined with annuloplasty, have proven to be efficient [10,13,15,21]. (Ischaemic) PMR is one of the rare conditions in which several Carpentier functional types of regurgitation (Type I, annular dilatation; Type II, leaflet prolapse and Type IIIb, restricted leaflet motion) can more or less coexist [21], which is important to realize and address during repair.…”

“…The most popular repair techniques included: resection of a prolapsing leaflet segment combined with annuloplasty [10,13,15] and reimplantation of the PM into the corresponding healthy PM head [6,8,9,13,16] or into the LV [7,8], with or without annuloplasty.…”

Papillary Muscle Rupture Following Non‐ST‐Elevation Myocardial Infarction: A Case Report

“…Case 1 was successfully managed surgically, while surgery was deferred in case 2 due to refractory cardiogenic shock and multi‐organ failure. The first case further highlights the known variability in coronary blood supply of papillary muscles, with the LAD (usually a wrap‐around type 3 vessel) supplying an apically inserted posteromedial papillary muscle …”

“…The first case further highlights the known variability in coronary blood supply of papillary muscles, with the LAD (usually a wrap-around type 3 vessel) supplying an apically inserted posteromedial papillary muscle. [6][7][8] The incidence of PMR following STEMI has declined, while it has increased in the setting of NSTEMI. There are two plausible explanations to this observation.…”

Spinal Subdural Haematoma in A Patient After Dobutamine Stress Test: An Unusual Occurrence

“…Adverse effects are reported to occur in up to 75% of cases which include ST segment changes on ECG (in up to 50% cases), chest pain, palpitations and significant supraventricular and ventricular arrhythmias. Various case reports published in literature show occurrence of broken heart syndrome (Takotsubo syndrome) [1][2][3] prolonged left ventricular dysfunction [4], transient global amnesia [5], cardiac rupture [6] and papillary muscle rupture [7]. We describe a case of spinal subdural haematoma occurring as adverse effects of dobutamine stress test, which to our knowledge, has not been reported in the literature so far.…”
