Catheter-based intervention for symptomatic patient with severe mitral regurgitation and very poor left ventricular systolic function - Safe but no room for complacency

Table 1 Echocardiographic characteristics of the patients

	LVEF(%)	LVEDD(mm)	Severity of MR	Cause of MR	Mid RV diameter (mm)	RV systolic dysfunction	PASP(mmHg)
Case 1	20	64	Moderate-to-severe	Secondary	51	Severe	50
Case 2	15	68	Severe	Secondary	42	Moderate	65
Case 3	20	70	Severe	Secondary	45	Mild	65

LVEDD: Left ventricular end-diastolic diameter; LVEF: Left ventricular ejection fraction; MR: Mitral regurgitation; PASP: Pulmonary arterial systolic pressure; RV: Right ventricle.
