Takotsubo Cardiomyopathy in a Patient with Preexisting Hypertrophic Cardiomyopathy.

ABSTRACT: Takotsubo cardiomyopathy (TCM) is a condition characterized by transient left ventricular dysfunction and apical ballooning, best seen on an echocardiogram or left ventriculogram. It mimics acute myocardial infarction but without evidence of coronary artery disease on an angiogram. Hypertrophic cardiomyopathy (HCM) is an autosomal dominant heart muscle disease that is significant with hypertrophy of the left ventricle with various morphologies. We hereby report a case of TCM in a male patient with a known history of HCM. The patient's hemodynamic findings were challenging because the TCM produced an increased left ventricular outflow tract (LVOT) gradient that was previously not seen on his prior echocardiogram or cardiac catheterizations. Assessment and continuous monitoring are warranted in such a rare case. Supportive care afterward with beta blockers, along with echocardiogram surveillance, are the mainstay of management of such a patient.

Project description:BACKGROUND: Takotsubo cardiomyopathy is a novel, yet well-described, reversible cardiomyopathy triggered by profound psychological or physical stress with a female predominance. OBJECTIVE: This review is designed to increase general clinician awareness about the diagnosis, incidence, pathogenesis, and therapies of this entity. DATA SOURCES: A complete search of multiple electronic databases (Pubmed, EMBASE, Science Citation Index) was carried out to identify all full-text, English-language articles published from 1980 to the present date and relevant to this review. REVIEW METHODS: The following search terms were used: takotsubo cardiomyopathy, stress-induced cardiomyopathy, and left ventricular apical ballooning syndrome. Citation lists from identified articles were subsequently reviewed and pertinent articles were further identified. RESULTS: Takotsubo cardiomyopathy is typically characterized by the following: 1) acute onset of ischemic-like chest pain or dyspnea, 2) transient apical and mid-ventricular regional wall-motion abnormality, 3) minor elevation of cardiac biomarkers, 4) dynamic electrocardiographic changes, and 5) the absence of epicardial coronary artery disease. The pathogenesis of the syndrome is unknown but has mostly been associated with acute emotional or physiologic stressors. Dote, Sato, Tateishi, Uchida, Ishihara (J Cardiol. 21(2):203-214, 1991); Desmet, Adriaenssens, Dens (Heart. 89(9):1027-1031, Sep., 2003); Bybee, Kara, Prasad, et al. (Ann Intern Med. 141(11):858-865, Dec 7, 2004); Sharkey, Lesser, Zenovich, et al. (Circulation. 111(4):472-479, Feb 1, 2005) The short and long-term prognosis of these patients is overwhelmingly favorable and often only requires supportive therapy. CONCLUSION: Whether an emotional or physical event precedes one's symptoms, it is apparent that takotsubo cardiomyopathy case presentations mimic ST-segment elevation myocardial infarction, and thus is an important entity to be recognized by the medical community.
