Impact of preoperative chronic lung disease on survival after surgical aortic valve replacement. The potential role of transcatheter tricuspid valve treatment in high-risk patients needs to be determined. Functional assessment of mitral regurgitation by transthoracic echocardiography using standardized imaging planes diagnostic accuracy and outcome implications. As an illustration, associated mitral regurgitation may lead to underestimation of the severity of aortic stenosis, as decreased stroke volume due to mitral regurgitation lowers the flow across the aortic valve and hence the aortic gradient. Recommended requirements of a heart valve centre modified from Chambers et al. Reported outcome after valve-sparing aortic root replacement for aortic root aneurysm:

LA volume, systolic pulmonary artery pressure, tricuspid regurgitation and annular size and RV function are important additional parameters. In inconclusive cases, BNP may be helpful, as its elevation during follow-up has been related to deterioration of LV function.
Decision making in VHD involves accurate diagnosis, timing of intervention, risk assessment and, based on these, selection of the most suitable type of intervention. Rather than setting arbitrary age limits, prosthesis choice should be discussed in detail with the informed patient, cardiologists and surgeons, taking into account the factors detailed below see tables of recommendations in section Tricuspid stenosis is often combined with tricuspid hv-0116, most frequently of rheumatic origin.

Usefulness of carvedilol in the treatment of chronic aortic valve regurgitation. Heart valve centres with highly specialized multidisciplinary teams, comprehensive equipment and sufficient volumes of procedures are required to deliver high-quality care and provide adequate training. Surveys and registries are needed to verify that real-life daily practice is in keeping with what is recommended in the guidelines, thus completing the loop between clinical research, writing of guidelines, disseminating them and implementing them into clinical practice.
When elevated pulmonary pressure is the only criterion to support the indication for surgery, confirmation of echo data by invasive measurement is recommended. Management of aortic regurgitation. Management of asymptomatic severe aortic stenosis remains controversial. Although valve replacement is the standard procedure in the majority of patients with aortic regurgitation, valve repair or valve-sparing surgery should be considered in patients with pliable non-calcified tricuspid or bicuspid valves who have a type I enlargement of the aortic root with normal cusp motion or type II cusp prolapse mechanism of aortic regurgitation.
The impact of earlier markers of LV dysfunction on postoperative outcome requires further research. Echocardiographic prediction of survival after surgical correction of organic mitral regurgitation.
Beta-blockers and spironolactone or eplerenone should also be considered as appropriate. Unfavourable characteristics for PMC can be defined by the presence of several of the following characteristics.

Randomized comparison of percutaneous repair and surgery for mitral regurgitation: In secondary mitral regurgitation, there is no conclusive evidence for a survival benefit after mitral valve intervention. Echocardiography is the key diagnostic tool. Its use is restricted to patients with inconclusive non-invasive investigations. Functional assessment of mitral regurgitation by transthoracic echocardiography using standardized imaging planes diagnostic accuracy and outcome implications.
Ischemic mitral regurgitation on the threshold of a solution: Patients with normal-flow, low-gradient aortic stenosis and preserved ejection fraction data should be re-evaluated. Measurement of the aortic root and ascending aorta in the 2-dimensional 2D mode at four levels: The decision for management should be taken after multidisciplinary discussion involving cardiologists, surgeons and anaesthesiologists.
Lavry Blue LE CMR is the reference method for the evaluation of RV volumes and function and is hv-10016 particularly useful to evaluate the consequences of tricuspid regurgitation. Although these patients respond well to diuretic therapy, delaying surgery everesg likely to result in irreversible RV damage, organ failure and poor results of late surgical intervention.

Impact of preoperative chronic lung disease on survival after surgical aortic valve replacement. In truly asymptomatic patients, regular assessment of LV function and physical condition are crucial to identify the optimal time for surgery.
Tricuspid stenosis is often overlooked and requires careful evaluation. A heart valve centre should have structured training programmes.

Definition of the anatomy of the everestt valve cusps and assessment of valve reparability should be provided by preoperative TOE if aortic valve repair or a valve-sparing surgery of the aortic root is considered. VKAs should be favoured when long-term anticoagulant therapy is needed in patients with a bioprosthesis. Measurement of LV function and dimensions.
