In experienced centres, the surgical outcome can be excellent [18]. As is mentioned in the 2011 guideline [1], extended Morrow procedure is a challenging operation in cardiac surgery, so there must be a learning curve before a surgeon can perform it perfectly. During the past 30 years, the largest group of Chinese obstructive HCM patients were treated in our institution. We have experienced a tough learning process and have gradually seen remarkable improvement by borrowing ideas from international communications and clinical exploration. According to our clinical practice, we had a morbidity of ∼7.4%, complete heart block (CHB) of ∼7.4% and MVR of 16.7% between 1996 and 2007. Moreover, the postoperative LVOT gradient was at an average level of 24 mmHg [19]. In the past few years, we have gradually improved the operating skills to tailor resection precisely, by properly increasing the extent of myectomy with precise discrimination, correction/resection of aberrant papillary muscles and mitral subvalvular apparatus abnormalities and using headlamps, long scalpels and forceps. This retrospective study shows that a much better clinical outcome, with a mortality of 0% (0/93), CHB rate of 3.2% (3 of 93), MVR of 10.8% and a mean postoperative LVOT gradient of 14.34 ± 13.44 mmHg, has been obtained since October 2009. Especially for the recent 20 cases, we have obtained results better than the average level, with a postoperative LVOT gradient of 1–9 mmHg.","tracks":[{"project":"0_colil","denotations":[{"id":"22761504-20884022-6879","span":{"begin":225,"end":227},"obj":"20884022"},{"id":"22761504-22068435-6880","span":{"begin":269,"end":270},"obj":"22068435"},{"id":"22761504-20137602-6881","span":{"begin":926,"end":928},"obj":"20137602"}],"attributes":[{"subj":"22761504-20884022-6879","pred":"source","obj":"0_colil"},{"subj":"22761504-22068435-6880","pred":"source","obj":"0_colil"},{"subj":"22761504-20137602-6881","pred":"source","obj":"0_colil"}]},{"project":"TEST0","denotations":[{"id":"22761504-63-69-6879","span":{"begin":225,"end":227},"obj":"[\"20884022\"]"},{"id":"22761504-39-44-6880","span":{"begin":269,"end":270},"obj":"[\"22068435\"]"},{"id":"22761504-78-84-6881","span":{"begin":926,"end":928},"obj":"[\"20137602\"]"}],"attributes":[{"subj":"22761504-63-69-6879","pred":"source","obj":"TEST0"},{"subj":"22761504-39-44-6880","pred":"source","obj":"TEST0"},{"subj":"22761504-78-84-6881","pred":"source","obj":"TEST0"}]},{"project":"2_test","denotations":[{"id":"22761504-20884022-28905045","span":{"begin":225,"end":227},"obj":"20884022"},{"id":"22761504-22068435-28905046","span":{"begin":269,"end":270},"obj":"22068435"},{"id":"22761504-20137602-28905047","span":{"begin":926,"end":928},"obj":"20137602"}],"attributes":[{"subj":"22761504-20884022-28905045","pred":"source","obj":"2_test"},{"subj":"22761504-22068435-28905046","pred":"source","obj":"2_test"},{"subj":"22761504-20137602-28905047","pred":"source","obj":"2_test"}]},{"project":"MyTest","denotations":[{"id":"22761504-20884022-28905045","span":{"begin":225,"end":227},"obj":"20884022"},{"id":"22761504-22068435-28905046","span":{"begin":269,"end":270},"obj":"22068435"},{"id":"22761504-20137602-28905047","span":{"begin":926,"end":928},"obj":"20137602"}],"namespaces":[{"prefix":"_base","uri":"https://www.uniprot.org/uniprot/testbase"},{"prefix":"UniProtKB","uri":"https://www.uniprot.org/uniprot/"},{"prefix":"uniprot","uri":"https://www.uniprot.org/uniprotkb/"}],"attributes":[{"subj":"22761504-20884022-28905045","pred":"source","obj":"MyTest"},{"subj":"22761504-22068435-28905046","pred":"source","obj":"MyTest"},{"subj":"22761504-20137602-28905047","pred":"source","obj":"MyTest"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"0_colil","color":"#93e4ec","default":true},{"id":"TEST0","color":"#ecda93"},{"id":"2_test","color":"#c093ec"},{"id":"MyTest","color":"#93eca6"}]}]}}
