Key result
Medical therapy completely resolved tachycardia-induced severe tricuspid regurgitation without the need for surgery in a single patient.
Case Report (n=1)
This case demonstrates that tachycardia-induced severe secondary tricuspid regurgitation and annular dilation can completely resolve with medical therapy alone, challenging the notion that surgical intervention is always required.

May support medical therapy for tachycardia-induced tricuspid regurgitation; leaves open generalizability from this single case.
Secondary tricuspid regurgitation (TR) primarily develops due to left heart failure or primary pulmonary diseases. Tricuspid annular dilation, which is commonly caused by right ventricular volume and pressure overload followed by right ventricle dilation, is believed to be the main mechanism underlying secondary TR. It is reported that once the tricuspid annulus is dilated, its size cannot spontaneously return to normal, and it may continue to dilate. These reports also suggest the use of an aggressive surgical approach for secondary TR. In the present report, we describe a case of tachycardia-induced severe TR that was completely resolved without the need for surgery.

Yang et al. (2015) conducted a case report in Tachycardia-induced right heart failure and severe tricuspid regurgitation (n=1). Medication was evaluated on Resolution of severe tricuspid regurgitation. Medical therapy completely resolved tachycardia-induced severe tricuspid regurgitation without the need for surgery in a single patient.
