This report presents the first case of complete resolution of ascites after transcoronary ablation of septal hypertrophy (TASH) in a cirrhotic patient with concomitant hypertrophic cardiomyopathy (HOCM). A 52-years-old woman with decompensated alcoholic liver cirrhosis was referred to our department for placement of a transjugular intrahepatic portosystemic stent shunt (TIPS) to treat her refractory ascites. The initial treatment with furosemide and spironolactone had to be discontinued because of severe hyponatriemia and an increase of creatinine levels. During further evaluation, HOCM was diagnosed by echocardiography and cardiac catheterization. We performed TASH in order to relieve the dynamic obstruction of the ventricular outflow tract, and the ascites completely resolved without further interventions.
