A 77-year-old woman was referred to perform a first and elective transthoracic echocardiography for occasionally detection of centrum cordis systolic murmur. Two hours before the echocardiography, she had suffered a robbery, and sudden palpitations and dyspnea were emerged.
The echocardiography showed mild dilatation of the left ventricle (end-diastolic volume: 141 ml, end-systolic volume: 66 ml), mild reduction of the left ventricular ejection fraction (53%) with apical ballooning [Figure 1]a, yellow arrow], degenerative moderate-to-severe mitral regurgitation [Figure 1]b, and moderate aortic regurgitation [Figure 1]c. Sinus rhythm with weak negative T-waves in inferior and V3-V6 leads was observed an ECG, and a moderate troponin elevation was detected (HS-Troponin T 48 ng/l– n. v. <14 ng/L). Coronary angiography did not reveal coronary stenosis/occlusion [Figure 1]d and [Figure 1]e. In few days, the wall motion abnormality was resolved in the absence of edema and/or late gadolinium enhancement in the cardiac magnetic resonance imaging [Figure 1]f and [Figure 1]g with no change in mitral/aortic regurgitation [Figure 1]h and [Figure 1]i [Video 1].

Subsequently, after 2 months, because of recurrent episodes of pulmonary edema, despite the aggressive medical treatment with β-blockers, angiotensin-converting enzyme inhibitors, and diuretics, the patient was scheduled for aortic and mitral valve replacement with biological prostheses. In early postoperative period, despite the normally functioning valvular prosthesis [Figure 1]k, the patient developed severe global left ventricular systolic dysfunction [Figure 1]j too severe to be explained only by preload and afterload changes after valvular replacement. After 3 months of optimal medical therapy, there was no improvement in left ventricular function (ejection fraction: 20%, end-diastolic volume: 154 ml, end-systolic volume: 123 ml); therefore, an Implantable cardiac defibrillator was implanted for the primary prevention of sudden cardiac death [Figure 1]l.
Takotsubo cardiomyopathy, which derives its name from the Japanese word Takotsubo (“octopus pot”), is characterized by transient left ventricular dysfunction with a variety of wall-motion abnormalities. It predominantly affects elderly women and is often preceded by an emotional or physical trigger (as robbery). In the acute phase, the clinical presentation, electrocardiographic findings, and biomarker profiles are often similar to those of an acute coronary syndrome. In long-term follow-up, a recurrent Takotsubo syndrome is possible and could impair the patient's prognosis., Data on recurrence of Takotsubo syndrome are limited: 5-year recurrence rates of 5%–22% have been reported, with the second episode occurring 3 months to 10 years after the first episode and also were reported recurrence of Takotsubo syndrome with a different anatomical variant.,, In our case, the patient with Takotsubo cardiomyopathy and heart failure due to degenerative mitral and aortic regurgitation underwent the valve replacement surgery with early recurrence of left ventricular systolic dysfunction. Thus, Takotsubo cardiomyopathy may be considered as a risk factor of the postoperative left ventricular dysfunction triggered by surgical/anesthetic procedure.
Despite that to our best knowledge, this is the first case of heart failure due to Takotsubo cardiomyopathy in a patient with mitral and aortic regurgitation and an early recurrence of left ventricular systolic dysfunction after valve replacement surgery.
