Delayed papillary muscle rupture after radiofrequency catheter ablation: A case report.

Background: With an increased number of surgical procedures involving the mitral annular region, the risk of mitral valve prolapse (MVP) has also increased. Previous studies have reported that worsening of MVP occurred early after radiofrequency catheter ablation (RFCA) at papillary muscles in ventricular tachycardia (VT) patients with preoperative MVP.

Case Summary: We report a case where MVP and papillary muscle rupture occurred 2 wk after RFCA in a papillary muscle originated VT patient without mitral valve regurgitation or prolapse before.

Takotsubo cardiomyopathy associated with bronchoscopic operation: A case report.

Background: Takotsubo cardiomyopathy (TTC), a syndrome of acute left ventricular (LV) dysfunction, is characterized by transitory hypokinesis of LV apices with compensatory hyperkinesis of the LV basal region. The symptoms of TTC mimic acute myocardial infarction, without significant coronary stenoses on coronary angiography. Echocardiogram plays a key role in the diagnosis and prognosis of TTC.

[Clinical study of idiopathic dilated cardiomyopathy complicated by left ventricular aneurysm].

Objective: To examine the hemodynamic and electrophysiological influence of left ventricular aneurysm (LVA) formation in patients with idiopathic dilated cardiomyopathy (IDCM).

Methods: All hospital records were retrospectively reviewed from IDCM patients admitted to our hospital between 2003 and 2008. Patients with coronary angiography evidenced ischemic cardiomyopathy were excluded.
