An 80-year-old female patient with a prior history of hypertension, chronic hepatitis C carrier, paroxysmal atrial fibrillation, cerebrovascular accident, and rheumatic heart disease with known severe MR. She was admitted to the cardiac intensive care unit due to pulmonary congestion.\nOn examination, she was in respiratory distress, her respiratory rate was 30 breaths/min, and her oxygen saturation was 86%. She had a clearly audible pansystolic murmur, and her lung examination was suggestive for pulmonary oedema.\nTransoesophageal echocardiography showed severe MR with practically non-coapting leaflets. An IABP was inserted 24 h prior to the procedure when the patient was euvolemic after diuretic therapy, with the aim of altering LV geometry to optimize the chances of success of MC by improving leaflet coaptation surface length and annular diameter. Baseline average annular diameter on TOE was 48 mm and the average coaptation surface length was 1.8 mm. After insertion of IABP, the average annular diameter decreased to 39 mm and the average coaptation surface length increased to 5.2 mm. Three mitral clips were implanted reducing MR severity from severe to mild-moderate and atrial V-wave from 60 to 25 mmHg (Figure; , Videos S5–S7).\nThe IABP was removed 24 h following the MC procedure after assuring stable haemodynamic and euvolemic status. The patient was discharged a few days later in good condition, with no additional episodes of pulmonary oedema. Three months after discharge, the patient was stable at NYHA functional Class I. Follow-up TTE showed mild-moderate MR and mild-moderate LV systolic function (EF 45%).
A 74-year-old female patient with a prior history of hypertension, hyperlipidaemia, diabetes, asthma, chronic renal failure, and ischaemic heart disease. Two months prior to her admission, she was treated in the cardiac intensive care unit for inferior-lateral ST-elevation myocardial infarction and underwent percutaneous coronary intervention (PCI) to the left circumflex (LCX) artery.\nOn examination, she was in respiratory distress (25 breaths/min) and her oxygen saturation was 86% on room air. Upon auscultation, she had a clear audible systolic murmur radiating to her left axilla, had diminished lung sounds in the bases and crackles suggestive for pulmonary oedema.\nThe patient did not improve despite maximal medical therapy and remained in NYHA Classes III–IV. Transoesophageal echocardiography showed severe MR with practically no leaflet coaptation (‘Free MR’), and other causes for severe MR (VSD/papillary muscle rupture, etc.) were excluded. Prior to the procedure an IABP was placed for 48 h to help maintain clinical stability and euvolemic status, and to achieve LV geometry alteration thus allowing better leaflet coaptation to optimize MC success. Mitral valve measurements using TOE showed an average annular diameter of 42 mm, and coaptation surface length of 1.9 mm. After insertion of IABP, the average annular diameter was 34 mm and the average coaptation surface length was 4.4 mm (Figure); see , Videos S3 and S4). The patient underwent implantation of three MCs, with a good overall results and improvement of the MR from severe to mild-moderate.\nFollowing the MC procedure for 48 h, the patient was weaned from the IABP after assuring stable haemodynamic status. The patient was discharged a few days later in good condition, with major improvement in NYHA symptoms and no additional episodes of pulmonary oedema. Three months after discharge, the patient was stable at NYHA Class II. Follow-up TTE showed moderate MR with moderately reduced LV function (EF 40%).
