Vanishing of ruptured adrenal mass with takotsubo cardiomyopathy.

A 45-year-old male suddenly experienced left-flank abdominal pain. Echocardiography revealed akinesis of the 'takotsubo cardiomyopathy' type. He experienced a sudden haemodynamic collapse (blood pressure, 324/154 mmHg; pulse rate, 180 beats/min) during emergency cardiac catheterisation. An abdominal computed tomography (CT) revealed expansion of a soft tissue mass 64 × 33 mm in dimension in the left adrenal region, with accumulation of fluid surrounding the left pararenal space. Three days after the attack, his urinary catecholamine concentrations were slightly elevated. We suspected the patient as having a pheochromocytoma followed by acute haemorrhagic rupture, based on signatures of adrenal mass, 'takotsubo cardiomyopathy', and the hypertensive crisis. Over the next few weeks, he recovered well as an outpatient, and his blood pressure remained around 110/60 mmHg without medication. Three weeks after the attack, an abdominal CT showed shrinkage of the ruptured adrenal mass (to a diameter of 30 mm) and absorption of the retroperitoneal hematoma. On day 190 after the attack, abdominal CT did not detect any left adrenal mass. This is the first report of the case showing a complete vanishing of ruptured adrenal mass with takotsubo cardiomyopathy. Although surgical approaches for ruptured adrenal mass involve either emergency or elective surgery, the patients did not need even the elective surgery. Accumulation of the similar cases may unravel clinical factors predicting self-limiting of the ruptured adrenal mass to avoid unnecessary risky surgery.

A single pathophysiological pathway in Takotsubo cardiomyopathy: Catecholaminergic stress.

BACKGROUND: Takotsubo cardiomyopathy (TTC) continues to be under-diagnosed, due to its varying presentation, with potentially serious consequences if treatment is delayed. AIMS: To demonstrate the consistent involvement of catecholaminergic stress in TTC, regardless of the trigger. METHODS: Between 01 July 2009 and 31 August 2013, patients managed in our centre for thoracic pain syndrome, with or without troponin release, were followed up prospectively. TTC was diagnosed from the apical ballooning seen on left ventricular imaging (angiography or transthoracic echocardiography) in the absence of a significant coronary artery lesion. Triggers (emotional trauma, surgical stress and ß2-mimetic intoxication) were recorded; catecholamine-secreting tumours were screened for with a urinary methoxylate-derivative assay. RESULTS: TTC was diagnosed in 40 out of 2754 (1.5%) patients with thoracic pain syndrome, with or without troponin release. Triggers were emotional trauma (n=29, 72.5%), surgical stress (n=5, 12.5%), adrenergic intoxication (n=3, 7.5%) and catecholaminergic tumour (n=3, 7.5%). Mean left ventricular ejection fraction at admission was 38.0 ± 15.7%. Eight (20%) patients initially showed cardiogenic shock. In-hospital mortality was 7.5%, with no deaths from cardiogenic causes. Thirty-five (94.6%) of the survivors had recovered a normal left ventricular ejection fraction (> 55%) by discharge. CONCLUSION: Whatever the trigger, the common denominator in TTC is catecholaminergic stress. Classically suggested after emotional trauma, TTC may also be induced by surgical stress or endogenous or iatrogenic ß2-mimetic intoxication. The various contexts all have a similarly excellent cardiovascular prognosis if treated early.

Cardiogenic shock with basal transient left ventricular ballooning (Takotsubo-like cardiomyopathy) as first presentation of pheochromocytoma.

Pheochromocytoma is a rare tumor that produces a distant effect by secretion of catecholamines. This tumor usually presents with hypertension and palpitations but it may also cause cardiogenic shock because of catecholamine-induced myocardial dysfunction. We describe a rare case of Takotsubo-like cardiomyopathy as first manifestation of pheochromocytoma with an unusual onset characterized by severe hypotension and transient basal left ventricular ballooning ('inverted' Takotsubo-like cardiomyopathy).
